Following severe cerebrovascular accidents, patients are often unable to dress themselves. Little is known about the persistence and treatment of this impairment. Study 1 followed 23 patients who were (1) completely dependent on others for help with dressing (2) for two weeks continually until their discharge from the rehabilitation unit. Study 2, a randomized controlled trial of 24 patients, examined the effects of errorless learning and RehaGoal App-based dressing practice on recovery in dressing ability-impaired patients who also experienced visuospatial neglect and/or apraxia. The control and intervention groups both underwent a standard therapy in the rehab unit; the intervention group additionally received dressing training (seven sessions of 45 min). The primary outcome measure was the score on an adapted version of the Nottingham Stroke Dressing Assessment; secondary outcome measures were the Barthel Index and Functional Independence Measure. Less than one-third of the patients in Study1 , showed improvement. In Study 2 , the intervention produced no specific effect on patients' dressing ability. However, apraxia and neglect predicted improvement for both groups. If patients depend completely on assistance for dressing for two weeks, prospects for recovery are limited. Future studies should include additional intervention sessions and incorporate treatments for neglect or apraxia.

Apraxia is widely used to describe one of the more disabling deficits following left strokes. The role of rehabilitation in treating apraxic stroke patients remains unclear. This systematic review was conducted to study the impacts of various rehabilitation interventions on the limb apraxia post-stroke. PubMed, SCOPUS, PEDro, CINAHL, MEDLINE, REHABDATA, and Web of Science were searched for the experimental studies that investigated the effects of the rehabilitation interventions on apraxia in patients with stroke. The methodological quality was rated using the Physiotherapy Evidence Database scale (PEDro). Six studies met our inclusion criteria in this systematic review. Four were randomized controlled trials, pilot ( n  = 1), and case study ( n  = 1). The scores on the PEDro scale ranged from two to eight, with a median of seven. The results showed some evidence for the effects of strategy training and gesture training interventions on the cognitive functions, motor activities, and activities of daily livings outcomes poststroke. The preliminary findings showed that the effects of the strategy training and the gesture training on apraxia in patients with stroke are promising. Further randomized controlled trials with long-term follow-ups are strongly needed.

Objective: To analyze the effectiveness of a home-based restorative and compensatory upper limb apraxia (ULA) rehabilitation program., Design: Randomized controlled trial., Setting: Neurology Unit of San Cecilio Hospital and 2 private and specialized health care centers., Participants: Community dwelling participants (N=38) between the ages of 25 and 95 years old (sex ratio, 1:1) with unilateral mild-to-moderate poststroke lesions (time of evolution since stroke, 12.03±8.98mo) and secondary ULA., Interventions: Participants were randomly assigned to an 8-week combined ULA functional rehabilitation group (n=19) 3 days per week for 30 minutes or to a traditional health care education protocol group (n=19) once a month for 8 weeks. Both interventions were conducted at home., Main Outcome Measures: Sociodemographic and clinical data, Barthel Index (primary outcome), Lawton and Brody Scale, observation and scoring activities of daily living, the De Renzi tests for ideational and ideomotor apraxia and imitating gestures test, recognition of gestures, test for upper limb apraxia , and stroke-specific quality of life scale were assessed at 3 time points: baseline, posttreatment (8wk), and follow-up (8wk)., Results: There were statistically significant differences among the groups regarding ideomotor apraxia, imitating gestures, global recognition of gestures, intransitive gestures, and comprehension of gesture production (P<.05) in favor of the experimental group. However, no statistically significant differences were found between the groups regarding functionality or quality of life (P>.05). Regarding the within-group effect, statistically significant differences were found in all neuropsychological outcomes at posttreatment and follow-up (P<.05)., Conclusion: A functional rehabilitation program was found to be superior to a traditional health care education program and resulted in improvements in neuropsychological functioning in ULA poststroke. Conventional education showed an insufficient effect on apraxia recovery. Further studies with larger sample sizes are needed to determine the effect of rehabilitation strategies on functionality and quality of life of poststroke ULA patients., (Copyright © 2021 American Congress of Rehabilitation Medicine.

Left hemisphere stroke frequently leads to limb apraxia, a disorder that has been reported to impact independence in daily life and rehabilitation success. Nonetheless, there is a shortcoming in research and availability of applicable trainings. Further, to date, anosognosia for limb apraxia has largely been neglected. Therefore, we developed a Naturalistic Action Therapy that trains object selection and application with an errorless learning approach and which includes supported self-evaluation. The current study presents the results of two stroke patients participating in the training. The procedure entailed two baseline and one post-training sessions including standardized limb apraxia and anosognosia assessments as well as 18 naturalistic action tasks. The training consisted of 15 sessions during which 4-6 of the 18 naturalistic action tasks (e.g., pour water into a glass, make a phone call) were trained. Both patients showed improvement in trained and untrained tasks as well as in standardized apraxia and anosognosia assessments. Training effects appeared strongest for the trained items. The procedure is documented in detail and easy to administer and thus may have the potential to be applied by relatives. The results of this pilot-study are promising and suggest that the approach is suitable for further evaluation.

We report the case of M.B. who demonstrated severe optic ataxia with the right hand following stroke in the left hemisphere. The clinical picture may shed light on both the pathological characteristics of reaching and grasping actions, and potential rehabilitation strategies for optic ataxia. First, M.B. demonstrated a dissociation between severely impaired reaching and relatively spared grasping and tool use skills and knowledge, which confirms that grasping may be more intermingled with non-motoric cognitive mechanisms than reaching. Besides, M.B.'s reaching performance was sensitive to movement repetition. We observed a substitution effect: Reaching time decreased if M.B. repeatedly reached toward the same object but increased when object identity changed. This may imply that not only object localization but also object identity, is integrated into movement programming in reach-to-grasp tasks. Second, studying M.B.'s spontaneous compensation strategies ascertained that the mere repetition of reaching movements had a positive effect, to the point M.B. almost recovered to normal level after an intensive one-day repetitive training session. This case study seems to provide one of the first examples of optic ataxia rehabilitation. Reaching skills can be trained by repetitive training even two years post-stroke and despite the presence of visuo-imitative apraxia.

A previously independent 66-yr-old right-handed man presented with right-sided weakness, preferring the lower limbs with additional impaired gait and dysarthria for 1-day duration. Imaging found a large left hemispheric anterior cerebral artery ischemic infarction with multiple lacunar infarcts. He exhibited frontal, callosal, and posterior variants of alien hand syndrome, which impeded activities of daily living. Though limited in evidence, a trial of clonazepam was initiated based on previous case reports describing suspected efficacy. Botulinum toxin A was not used given the patient's immediate need and limited hospital length of stay. Right upper limb constricting therapies improved intermanual conflict and spontaneous grasping and levitation (arm elevation in retroflexion) activity; however, concomitant left upper limb motor apraxia complicated task-oriented activities. The combination of pharmaceutical and therapeutic interventions improved the patient's quality of life as assessed by clinical observation, functional independence measures from 41 to 57, and patient reporting. This case report aims to increase awareness of a potential barrier to rehabilitation of a debilitating and rare condition and to discuss current assessment tools and treatment options supported by available evidence.

Purpose To incorporate evidence-based practice into clinical settings, there is a need for efficient, effective ways to share information from research to speech-language pathologists (SLPs) and to students preparing to become SLPs. The purpose of this study was to implement and evaluate a method for teaching undergraduate student clinicians to use empirically supported practices in vocabulary instruction during shared storybook reading with preschoolers. Method Undergraduate students enrolled in a semester-long preschool practicum participated in the study. In Study 1, 11 students participated in a multiple-baseline, single-case design. In Study 2, an additional 10 students were included in a quasi-experimental group design. All students completed prerecorded, online teaching modules that taught empirically supported practices for teaching vocabulary during shared storybook reading. Half of the students received weekly e-mails with performance feedback. Targeted practices included selection of appropriate vocabulary targets, explicit teaching, and use of interactive teaching strategies. Results In Study 1, treatment effects were observed for targeted practices for many of the student clinicians. In Study 2, group comparisons indicated an effect of e-mail performance feedback for 1 of 3 outcomes with a large effect size. Conclusion Prerecorded teaching modules may be an efficient, effective way to teach specific empirically supported practices to undergraduate student clinicians. E-mail feedback might improve use of taught practices for some students or for some practices. Future studies can examine the potential of these types of teaching modules for other outcomes or with groups of practicing SLPs.

Social interaction is impaired in schizophrenia, including the use of hand gestures, which is linked to poor social perception and outcome. Brain imaging suggests reduced neural activity in a left-lateralized frontoparietal network during gesture preparation; therefore, gesturing might be improved through facilitation of left hemispheric brain areas or via disruption of interhemispheric inhibition from the right homolog. This study tested whether repetitive transcranial magnetic stimulation (rTMS) protocols would improve gesture performance in schizophrenia. This randomized, placebo-controlled, double-blind, crossover trial applied 3 different protocols of rTMS separated by 48 h. Twenty right-handed schizophrenia patients and 20 matched healthy controls received facilitatory intermittent theta burst stimulation (iTBS) over the left inferior frontal gyrus (IFG), inhibitory continuous theta burst stimulation (cTBS) over right inferior parietal lobe (IPL), and placebo over left IPL in randomized order. Primary outcome was change in the test of upper limb apraxia (TULIA), rated from video recordings of hand gesture performance. Secondary outcome was change in manual dexterity using the coin rotation task. Participants improved on both tasks following rTMS compared with baseline. Only patients improved gesture performance following right IPL cTBS compared with placebo (P = .013). The results of the coin rotation parallel those of the TULIA, with improvements following right IPL cTBS in patients (P = .001). Single sessions of cTBS on the right IPL substantially improved both gesture performance accuracy and manual dexterity. The findings point toward an inhibition of interhemispheric rivalry as a potential mechanism of action., (© The Author(s) 2019.

The present study investigated the effects of different types of recasts and prompts on the rate of repair and spontaneous use of novel vocabulary by eight children with severe motor speech disabilities who used speech-generating technologies to communicate. Data came from 60 transcripts of clinical sessions that were part of a conversation-based intervention designed to teach them pronouns, verbs, and verb inflections. The results showed that, when presented alone, interrogative choice and declarative recasts led to the highest rates of child repair. The results also showed that when children were presented with recasts and prompts to repair, the rate of repair increased. Spontaneous use of linguistic targets was significantly and positively related to conversational sequences where the adult recast was followed by child repair. These findings suggest that using different recast types and prompts to repair may be beneficial for spontaneous use of linguistic targets in this population.

This study aimed to detect patterns in clause construction structural changes produced by four participants aged 9;5-13;7 (years;months) with motor speech disorders who used speech-generating devices. Sequences of adult-child interactions, drawn from the data of a larger study focused on enhancing vocabulary and grammar skills, were examined. This current study comprises a secondary analysis of a corpus of 29 conversations totalling 808.36 min, analysing clause structures by type, linguistic complexity, and intensity of adult prompts (number of turns). Results show that, over time, the participants' clause structure complexity increased through addition of phrase-internal elements such as inflections, articles, and prepositions. Use of specific grammatical elements followed the developmental stages observed in children with typical development. For all participants, the personal pronoun I (first-person singular) emerged before she , he (third-person singular), and we or they (plural). Participants with the highest number of adult-child co-constructed clauses also had the highest number of well-formed clauses. The intensity of adult prompts increased as clause structures became more complex and as participants needed more support. Implications for practice and theory are discussed.

The purpose of this study was to explore the errors and revisions (i.e., repairs) that 3- and 4-year-old children who require augmentative and alternative communication (AAC) make as they construct 2-3-word utterances using graphic symbols. The current study involves supplemental analyses from a previously published manuscript. Various types of errors and revisions for four different semantic-syntactic structures-agent-action-object, entity-attribute, entity-locative, and possessor-entity-were analysed to explore patterns and differences across utterance types. Results indicated that the majority of errors were made during the baseline phase, and that error types varied depending on the utterance type. For example, inversions were common for agent-action-object utterances, but omissions were common for entity-attribute utterances. When the participants revised their utterances, the resulting messages were more accurate the majority of the time, regardless of utterance type. Past research has highlighted frequent word order errors within graphic symbol messages, but the current results indicate that error types are dependent upon utterance type. A more refined approach, then, is required to better our understanding of how children approach the task of learning to produce graphic symbol utterances.

Objective: Speech sound errors are common in people with a variety of communication disorders and can result in impaired message transmission to listeners. Valid and reliable metrics exist to quantify this problem, but they are rarely used in clinical settings due to the time-intensive nature of speech transcription by humans. Automated speech recognition (ASR) technologies have advanced substantially in recent years, enabling them to serve as realistic proxies for human listeners. This study aimed to determine how closely transcription scores from human listeners correspond to scores from an ASR system., Patients and Methods: Sentence recordings from 10 stroke survivors with aphasia and apraxia of speech were transcribed orthographically by 3 listeners and a web-based ASR service. Adjusted transcription scores were calculated for all samples based on accuracy of transcribed content words., Results: As expected, transcription scores were significantly higher for the humans than for ASR. However, intraclass correlations revealed excellent agreement among the humans and ASR systems, and the systematically lower scores for computer speech recognition were effectively equalized simply by adding the regression intercept., Conclusions: The results suggest the clinical feasibility of supplementing or substituting human transcriptions with computer-generated scores, though extension to other speech disorders requires further research., (© 2019 S.

The purpose of this study was to evaluate the effect of explicit vocabulary instruction during shared reading experiences on the acquisition of receptive academic vocabulary for children with complex communication needs. A single-subject, multiple-probe design was used. Three preschool-aged children (i.e., one with autism spectrum disorder, one with developmental delay, and one with a rare genetic disorder) were each taught two sets of vocabulary words. Intervention consisted of explicit vocabulary instruction associated with shared reading of academic texts. All three children acquired 10 targeted academic vocabulary items receptively and maintained vocabulary knowledge for at least 4 weeks. Data also suggest probable generalization to new representations. Additionally, participants became more adept at learning via this method, acquiring the second vocabulary set in significantly less time. Results indicate that explicit vocabulary instruction during shared reading experiences can be effective for teaching receptive vocabulary to children with complex communication needs.

The use of early verbal categories, their event types, and the emergence of verbal inflections (-ing, -s, and -ed) were analyzed in data from four participants with motor speech disorders aged 9;5-13;9 (years;months) who used speech-generating devices to converse with a familiar adult. The study was conducted through a secondary analysis of a corpus of data collected as part of another study. It documents the production of verbs and the emergence of verb inflections in natural conversations between each of the participants and a member of their educational team over a period of up to 10 months. All participants used both action and state verbs, although action verbs were dominant. The emergence of the inflections -ing, -s, and -ed varied and were distributed selectively with different verb categories and event types. The results are discussed in terms of language development and are considered in terms of the findings from research with children without disabilities, which suggest that action verbs precede state verbs, and inflections are primarily acquired based on their correspondence to the verbal category (action-state). Implications for theory, practice, and further research are discussed.

Purpose: A Phase I pilot study was designed to collect preliminary evidence on the use of the Kaufman Speech to Language Protocol (K-SLP; Kaufman, 2014) to treat children with childhood apraxia of speech. We hypothesized that the K-SLP approach would result in more accurate speech production in targeted words, whereas untrained (control) words and speech sounds would remain unchanged., Method: A single-case multiple-baseline across behaviors experimental design was used to see if experimental feasibility could be demonstrated. Two children each received a total of 12 1-hr treatment sessions over 3 weeks. The children's response to treatment and experimental control was measured by administering baseline, treatment, and posttreatment probes., Results: Both children showed some response to treatment, as measured by percent phonemes correct; however, the response to treatment varied. In general, for the treated words that improved with therapy, accuracy was maintained above baseline level during the maintenance phase. Minimal generalization was observed for this study, with only 1 participant generalizing treatment gains to 2 sets of untrained (similar) words., Conclusion: This Phase I pilot study provides limited preliminary evidence for the effectiveness of the K-SLP approach in treating childhood apraxia of speech in some children under the conditions specified in this study. Replication of these results in well-controlled studies is needed before this structured and operationalized version of the K-SLP approach can be recommended for clinical use.

The past decade has seen the emergence of rehabilitation treatments using virtual reality (VR) environments although translation into clinical practice has been limited so far. In this paper, an immersive VR rehabilitation training system endowed with wearable haptics is proposed for children with neuromotor impairments: it aims to enhance involvement and engagement of patients, to provide congruent multi-sensory afferent feedback during motor exercises and to benefit from the flexibility of VR in adapting exercises to the patient's need. An experimental rehabilitation session conducted with children with cerebral palsy (CP) and developmental dyspraxia (DD) has been performed to evaluate the usability of the system and proof of concept trial of the proposed approach. We compared CP/DD performance with both typically developing children and adult control group. Results show the system was compliant with different levels of motor skills and allowed patients to complete the experimental rehabilitation session, with performance varying according to the expected motor abilities of different groups. Moreover, a kinematic assessmentbased on the presented system has been designed. Obtained results reflected different motor abilities of patients and participants, suggesting suitability of the proposed kinematic assessment as a motor function outcome.

Corticobasal degeneration (CBD) is a neurodegenerative disorder characterized by a combination of cortical and basal ganglia signs. We reported two cases treated with a bilateral upper limb rehabilitation tool with videogame based feedback for 3 time per week for 8 weeks. Both patients showed an improvement of pinch and grasp forces and motor function. However, both of them reported an increased upper limb pain. Bilateral upper limb mechanical device with exergame feedback was effective also in the two patients suffering of CBD for limiting the effects of apraxia by performing intensive purposeful task training.

Apraxia of speech is a motor speech disorder in which messages from the brain to the mouth are disrupted, resulting in an inability for moving lips or tongue to the right place to pronounce sounds correctly. Current therapies for this condition involve a therapist that in one-on-one sessions conducts the exercises. Our aim is to work in the line of robotic therapies in which a robot is able to perform partially or autonomously a therapy session, endowing a social robot with the ability of assisting therapists in apraxia of speech rehabilitation exercises. Therefore, we integrate computer vision and machine learning techniques to detect the mouth pose of the user and, on top of that, our social robot performs autonomously the different steps of the therapy using multimodal interaction.

Purpose: Despite the widespread use of hand movements as visual and kinesthetic cues to facilitate accurate speech produced by individuals with speech sound disorders (SSDs), no experimental investigation of gestural cues that mimic that spatiotemporal parameters of speech sounds (e.g., holding fingers and thumb together and "popping" them to cue /p/) currently exists. The purpose of this study was to examine the effectiveness of manual mimicry cues within a multisensory intervention of persisting childhood apraxia of speech (CAS)., Method: A single-subject ABAB withdrawal design was implemented to assess the accuracy of vowel + /r/ combinations produced by a 21-year-old woman with persisting CAS. The effect of manual mimicry gestures paired with multisensory therapy consisting of verbal instructions and visual modeling was assessed via clinician and naïve listener ratings of target sound accuracy., Results: According to the perceptual ratings of the treating clinician and 28 naïve listeners, the participant demonstrated improved speech sound accuracy as a function of the manual mimicry/multisensory therapy., Conclusions: These data offer preliminary support for the incorporation of gestural cues in therapy for CAS and other SSDs. The need for continued research on the interaction of speech and manual movements for individuals with SSDs is discussed.

When working with individuals with little or no functional speech, clinicians often recommend that communication partners use the client's augmentative and alternative communication (AAC) device when speaking to the client. This is broadly known as "augmented input" and is thought to enhance the client's learning of language form and content. The purpose of this systematic review was to determine the effects of augmented input on communication outcomes in persons with developmental disabilities and persons with childhood apraxia of speech who use aided AAC. Nineteen studies met the inclusion criteria. Each included study was reviewed in terms of participant characteristics, terminology used, symbol format, augmented input characteristics, outcomes measured, effectiveness, and study quality. Results indicate that augmented input can improve single-word vocabulary skills and expression of multi-symbol utterances; however, comprehension beyond the single word level has not been explored. Additionally, it is difficult to form conclusions about the effect of augmented input on specific diagnostic populations. Directions for future research are posited.

In this paper we report the effect of a combined transcranial direct current stimulation (tDCS) and speech language therapy on linguistic deficits following left brain damage in a stroke case. We show that simultaneous electrical excitatory stimulation to the left and inhibitory stimulation to the right parietal regions (dual-tDCS) affected writing and reading rehabilitation, enhancing speech therapy outcomes. The results of a comparison with healthy controls showed that application of dual-tDCS could improve, in particular, sub-lexical transcoding and, specifically, the reading of non-words with increasing length and complexity. Positive repercussions on patient's quality of functional communication were also ascertained. Significant changes were also found in other language and cognitive tasks not directly treated (comprehension and constructive apraxia).

Purpose: The purpose of this study was to evaluate the role of practice variability, through prosodic variation during speech sound training, in biofeedback treatment for children with childhood apraxia of speech. It was hypothesized that variable practice would facilitate speech sound learning., Method: Six children ages 8-16 years with persisting speech sound errors due to childhood apraxia of speech participated in a single-subject experimental design. For each participant, 2 speech sound targets were treated with ultrasound visual feedback training: one with prosodic variation (i.e., practicing sound targets in words and phrases spoken fast, slow, loud, as a question, command, and declarative), and one without prosodic variation. Each target was treated for half of the 1-hr session for 14 treatment sessions., Results: As measured by standardized effect sizes, all participants showed greater change on generalization probes for sound targets treated under the prosodic variation condition with mean effect sizes (d2) of 14.5 for targets treated with prosodic variation and 8.3 for targets treated without prosodic variation. The average increase in generalization scores was 38% in the prosodic variation condition compared to 31% without., Conclusions: Ultrasound visual feedback may facilitate speech sound learning and learning may be enhanced by treating speech sounds with explicit prosodic variation., Supplemental Materials: https://doi.org/10.23641/asha.5150119.

Purpose: The purpose of this investigation was to compare the effects of schedule of practice (i.e., blocked vs. random) on outcomes of Sound Production Treatment (SPT; Wambaugh, Kalinyak-Fliszar, West, & Doyle, 1998) for speakers with chronic acquired apraxia of speech and aphasia., Method: A combination of group and single-case experimental designs was used. Twenty participants each received SPT administered with randomized stimuli presentation (SPT-R) and SPT applied with blocked stimuli presentation (SPT-B). Treatment effects were examined with respect to accuracy of articulation as measured in treated and untreated experimental words produced during probes., Results: All participants demonstrated improved articulation of treated items with both practice schedules. Effect sizes were calculated to estimate magnitude of change for treated and untreated items by treatment condition. No significant differences were found for SPT-R and SPT-B relative to effect size. Percent change over the highest baseline performance was also calculated to provide a clinically relevant indication of improvement. Change scores associated with SPT-R were significantly higher than those for SPT-B for treated items but not untreated items., Conclusion: SPT can result in improved articulation regardless of schedule of practice. However, SPT-R may result in greater gains for treated items., Supplemental Materials: https://doi.org/10.23641/asha.5116831.

Purpose: This study aimed to test whether an approach to distinguishing errors arising in phonological processing from those arising in motor planning also predicts the extent to which repetition-based training can lead to improved production of difficult sound sequences., Method: Four individuals with acquired speech production impairment who produced consonant cluster errors involving deletion were examined using a repetition task. We compared the acoustic details of productions with deletion errors in target consonant clusters to singleton consonants. Changes in accuracy over the course of the study were also compared., Results: Two individuals produced deletion errors consistent with a phonological locus of the errors, and 2 individuals produced errors consistent with a motoric locus of the errors. The 2 individuals who made phonologically driven errors showed no change in performance on a repetition training task, whereas the 2 individuals with motoric errors improved in their production of both trained and untrained items., Conclusions: The results extend previous findings about a metric for identifying the source of sound production errors in individuals with both apraxia of speech and aphasia. In particular, this work may provide a tool for identifying predominant error types in individuals with complex deficits.

Apraxia of speech (AOS) is a motor speech disorder, most typically caused by stroke, which in its "pure" form (without other speech-language deficits) is very rare in clinical practice. Because some observable characteristics of AOS overlap with more common verbal communication neurologic syndromes (i.e. aphasia, dysarthria) distinguishing them may be difficult. The present study describes AOS in a 49-year-old right-handed male after left-hemispheric stroke. Analysis of his articulatory and prosodic abnormalities in the context of intact communicative abilities as well as description of symptoms dynamics over time provides valuable information for clinical diagnosis of this specific disorder and prognosis for its recovery. This in turn is the basis for the selection of appropriate rehabilitative interventions., (Copyright © 2016 Polish Neurological Society. Published by Elsevier Urban & Partner Sp. z o.o.

Background: Apraxia and Action Disorganisation Syndrome are characterised by an inability to use tools and carry out ordered sequences of movements in the absence of motor or sensory impairment. To date treatment for these complex but debilitating conditions has received little attention., Objectives: To provide an overview of apraxia and action disorganisation syndrome and its treatment, providing a state of the art summary for practitioners including likely future therapeutic directions., Method: Review of apraxia literature and treatment studies collated from internet searches involving MEDLINE, PubMed, PyscINFO and Google Scholar as well as the author's own catalogue., Results: Evidence for current restitution and compensatory approaches is critically reviewed, with limited evidence to date in support of either method. Strategy training is the most promising intervention type with no support for sensory and exploratory interventions, practice effects only for direct task-specific training, and modest support for gestural training., Conclusions: Larger controlled studies are needed but evidence is sufficient to indicate certain approaches over others. Advances in assistive technology have not translated into mainstream therapy but future interventions are likely to require a model-based approach which embraces current technologies in order to provide a more accessible, effective and cost-efficient approach to rehabilitation.

Purpose: The purpose of the study was to evaluate the effectiveness of speech-generating devices (SGDs) on the communication and language development of a 2-year-old boy with severe childhood apraxia of speech (CAS)., Methods: An A-B design was used over a treatment period of 1 year, followed by three additional follow-up measurements, in order to evaluate the implementation of SGDs in the speech therapy of a 2;7-year-old boy with severe CAS. In total, 53 therapy sessions were videotaped and analyzed to better understand his communicative (operationalized as means of communication) and linguistic (operationalized as intelligibility and consistency of speech-productions, lexical and grammatical development) development. The trend-lines of baseline phase A and intervention phase B were compared and percentage of non-overlapping data points were calculated to verify the value of the intervention., Results: The use of SGDs led to an immediate increase in the communicative development of the child. An increase in all linguistic variables was observed, with a latency effect of eight to nine treatment sessions., Conclusions: The implementation of SGDs in speech therapy has the potential to be highly effective in regards to both communicative and linguistic competencies in young children with severe CAS. Implications for Rehabilitation Childhood apraxia of speech (CAS) is a neurological speech sound disorder which results in significant deficits in speech production and lead to a higher risk for language, reading and spelling difficulties. Speech-generating devices (SGD), as one method of augmentative and alternative communication (AAC), can effectively enhance the communicative and linguistic development of children with severe CAS.

Background: Upper limb apraxia is a common disorder associated with stroke that can reduce patients' independence levels in activities of daily living and increase levels of disability. Traditional rehabilitation programs designed to promote the recovery of upper limb function have mainly focused on restorative or compensatory approaches. However, no previous studies have been completed that evaluate a combined intervention method approach, where patients concurrently receive cognitive training and learn compensatory strategies for enhancing daily living activities., Methods/design: This study will use a two-arm, assessor-blinded, parallel, randomized controlled trial design, involving 40 patients who present a left- or right-sided unilateral vascular lesion poststroke and a clinical diagnosis of upper limb apraxia. Participants will be randomized to either a combined functional rehabilitation or a traditional health education group. The experimental group will receive an 8-week combined functional program at home, including physical and occupational therapy focused on restorative and compensatory techniques for upper limb apraxia, 3 days per week in 30-min intervention periods. The control group will receive a conventional health education program once a month over 8 weeks, based on improving awareness of physical and functional limitations and facilitating the adaptation of patients to the home. Study outcomes will be assessed immediately postintervention and at the 2-month follow-up. The primary outcome measure will be basic activities of daily living skills as assessed with the Barthel Index. Secondary outcome measures will include the following: 1) the Lawton and Brody Instrumental Activities of Daily Living Scale, 2) the Observation and Scoring of ADL-Activities, 3) the De Renzi Test for Ideational Apraxia, 4) the De Renzi Test for Ideomotor Apraxia, 5) Recognition of Gestures, 6) the Test of Upper Limb Apraxia (TULIA), and 7) the Quality of Life Scale For Stroke (ECVI-38)., Discussion: This trial is expected to clarify the effectiveness of a combined functional rehabilitation approach compared to a conservative intervention for improving upper limb movement and function in poststroke patients., Trial Registration: Clinical Trial Gov number NCT02199093 . The protocol registration was received 23 July 2014. Participant enrollment began on 1 May 2014. The trial is expected to be completed in March 2016.

Objective: To compare the differences in the clinical efficacy on post-stroke speech disorder between scalp electric acupuncture (EA) under anatomic orientation combined with rehabilitation training and simple rehabilitation training., Methods: Sixty patients of post-stroke speech apraxia were randomized into an observation group and a control group, 30 cases in each one. In the observation group, under anatomic orientation, the scalp EA was adopted to the dominant hemisphere Broca area on the left cerebrum. Additionally, the speech rehabilitation training was combined. In the control group, the speech rehabilitation training was simply,used. The treatment lasted for 4 weeks totally. The speech movement program module in the psychological language assessment and treatment system of Chinese aphasia was used for the evident of efficacy assessment. The scores of counting, singing scale, repeating phonetic alphabet, repeating monosyllable and repeating disyllable were observed in the patients of the two groups. The assessment was done separately on the day of grouping and 4 weeks after treatment., Results: In 4 weeks of treatment, the scores of counting, singing scale, repeating phonetic alphabet, repeating monosyllable and repeating disyllable were all improved as compared with those before treatment in the two groups (all P<0. 001). The results in the observation group were better than those in the control group (all P< 0. 05). The total effective rate was 100. 0% (30/30) in the observation group, superior apparently to 53. 3% (16/30) in the control group (P<0. 001)., Conclusion: The scalp EA under anatomic orientation combined with' speech rehabilitation training obviously improves speech apraxia in stroke patients so that the speech disorder cani be relieved. The efficacy is better than that in simple rehabilitation training.

Purpose: This is a systematic review of assessment and treatment of cognitive and communicative abilities of individuals with acquired brain injury via telepractice versus in person. The a priori clinical questions were informed by previous research that highlights the importance of considering any functional implications of outcomes, determining disorder- and setting-specific concerns, and measuring the potential impact of diagnostic accuracy and treatment efficacy data on interpretation of findings., Method: A literature search of multiple databases (e.g., PubMed) was conducted using key words and study inclusion criteria associated with the clinical questions., Results: Ten group studies were accepted that addressed assessment of motor speech, language, and cognitive impairments; assessment of motor speech and language activity limitations/participation restrictions; and treatment of cognitive impairments and activity limitations/participation restrictions. In most cases, equivalence of outcomes was noted across service delivery methods., Conclusions: Limited findings, lack of diagnostic accuracy and treatment efficacy data, and heterogeneity of assessments and interventions precluded robust evaluation of clinical implications for telepractice equivalence and the broader area of telepractice efficacy. Future research is needed that will build upon current knowledge through replication. In addition, further evaluation at the impairment and activity limitation/participation restriction levels is needed.

In childhood apraxia of speech (CAS), children exhibit varying levels of speech intelligibility depending on the nature of errors in articulation and prosody. Augmentative and alternative communication (AAC) strategies are beneficial, and commonly adopted with children with CAS. This study focused on the decision-making process and strategies adopted by speech-language pathologists (SLPs) when simultaneously implementing interventions that focused on natural speech and AAC. Eight SLPs, with significant clinical experience in CAS and AAC interventions, participated in an online focus group. Thematic analysis revealed eight themes: key decision-making factors; treatment history and rationale; benefits; challenges; therapy strategies and activities; collaboration with team members; recommendations; and other comments. Results are discussed along with clinical implications and directions for future research.

Can the meaning of two-digit Arabic numbers be accessed independently of their verbal-phonological representations? To answer this question we explored the number processing of ZN, an aphasic patient with a syntactic deficit in digit-to-verbal transcoding, who could hardly read aloud two-digit numbers, but could read them as single digits ("four, two"). Neuropsychological examination showed that ZN's deficit was neither in the digit input nor in the phonological output processes, as he could copy and repeat two-digit numbers. His deficit thus lied in a central process that converts digits to abstract number words and sends this information to phonological retrieval processes. Crucially, in spite of this deficit in number transcoding, ZN's two-digit comprehension was spared in several ways: (1) he could calculate two-digit additions; (2) he showed good performance in a two-digit comparison task, and a continuous distance effect; and (3) his performance in a task of mapping numbers to positions on an unmarked number line showed a logarithmic (nonlinear) factor, indicating that he represented two-digit Arabic numbers as holistic two-digit quantities. Thus, at least these aspects of number comprehension can be performed without converting the two-digit number from digits to verbal representation.

The objective was to assess effectiveness of apraxia treatments using a systematic review. In contrast to previous reviews, each study was rated as to its applicability to occupational therapy practice and its focus on occupational performance using the FAME rating system (defined by four categories: Feasibility, Appropriateness, Meaningfulness, Effectiveness). This systematic review included eight studies: four randomized controlled trials (level 1 evidence) and four pre-post designs (level 3 evidence). Three treatment approaches were reported: errorless learning with training of details; gesture training; and strategy training. FAME scores ranged from A to C. All studies reported significant treatment effects, but only one demonstrated an impact on observed occupational performance that transferred from clinic to home., (Copyright 2014, SLACK Incorporated.)

This study aims to evaluate and predict outcome as part of routine quality assessment of an inpatient stroke rehabilitation programme. By relating functional outcome to patient characteristics, including variables from the quality of life domain, we aim to find a set of variables that can be useful for prognosis, stratification and programme improvement. Data were collected, before and after rehabilitation, from a prospective quality registration database. Included were 250 patients in inpatient stroke rehabilitation after sustaining a first or recurrent ischemic or haemorrhagic stroke. Functional status was measured with the Barthel Index and the Academic Medical Centre Linear Disability Score. Health-related quality of life (HrQoL) was measured with the COOP/WONCA and the Nottingham Health Profile. Significant improvements were found on all outcome measures. A lower functional admission score, older age, more severe stroke, more pain and more negative emotional reactions on admission were found to be independent predictors of a lower outcome score, explaining 39.5% of its variance. Subjective (HrQoL) factors such as negative emotion and pain have an adverse effect on outcome of stroke rehabilitation, in addition to stroke severity, age and functional status at admission. These factors need to be taken into account in screening, clinical decision making and treatment design.

Objective: Rett syndrome is a rare neurodevelopmental disorder that is usually associated with a mutation on the X-linked MECP2 gene. Hand function is particularly affected and we discuss theoretical and practical perspectives for optimising hand function in Rett syndrome., Methods: We reviewed the literature pertaining to hand function and stereotypies in Rett syndrome and developed a toolkit for their assessment and treatment., Results: There is little published information on management of hand function in Rett syndrome. We suggest assessment and treatment strategies based on available literature, clinical experience and grounded in theories of motor control and motor learning., Conclusion: Additional studies are needed to determine the best treatments for hand function in Rett syndrome. Meanwhile, clinical needs can be addressed by supplementing the evidence base with an understanding of the complexities of Rett syndrome, clinical experience, environmental enrichment animal studies and theories of motor control and motor learning.

Background: Stroke-induced paresis commands much attention during rehabilitation; other stroke-related consequences receive less consideration. Apraxia is a stroke disorder that may have important implications for rehabilitation and recovery., Objective: To investigate association of apraxia with stroke rehabilitation outcomes during inpatient rehabilitation., Methods: This cohort study compared patients with and without apraxia after a first left hemispheric stroke. All study patients received standard of care. Clinical measures were the Functional Independence Measure (FIM) and the upper extremity section of the Fugl-Meyer Assessment (FMA) administered upon admission and at discharge. Length of stay was also documented. Florida Apraxia Battery subtests were used to classify patients with apraxia., Results: Fifteen patients were included in this study, 10 of whom had apraxia. Data analysis revealed that patients with apraxia exhibited improvement from admission to discharge in clinical measures; however, admission FIM score was significantly lower compared to patients without apraxia. There was no statistically significant difference between groups on FMA score, length of stay, or amount of change on clinical measures., Conclusions: This study of acute patients found those with apraxia to be significantly less independent upon admission to inpatient rehabilitation compared to patients without apraxia. Although both groups improved a similar amount during rehabilitation, patients with apraxia discharged at a level of independence comparable to patients without apraxia upon admission. Such disparity in independence is of concern, and apraxia as a factor in stroke rehabilitation and recovery deserves further attention.

CogWatch is an assistive system to re-train stroke survivors suffering from Apraxia or Action Disorganization Syndrome (AADS) to complete activities of daily living (ADLs). This paper describes the approach to real-time planning based on a Markov Decision Process (MDP), and demonstrates its ability to improve task's performance via user simulation. The paper concludes with a discussion of the remaining challenges and future enhancements.

Purpose: Two objectives are being pursued: (1) to describe and compare the level of social participation of children aged 5-13 with developmental coordination disorder (DCD) to children of the same age with typical development (TD) and (2) to describe and compare the level of social participation of two subgroups of youths with DCD, e.g. children with dyspraxia affecting both the motor sphere and the verbal sphere (mixed dyspraxia) and children with developmental dyspraxia., Method: This cross-sectional study was conducted among 27 youngsters with DCD: 9 having developmental dyspraxia and 18 having mixed dyspraxia, compared to 27 same-age peers with TD. Life habits (LIFE-H) for children was used to measure social participation., Results: Levels of lifestyle achievements among youngsters with DCD are significantly lower than those of TD youngsters in all categories. Noteworthy differences were found between subgroups of youngsters with DCD in the categories of life habits related to communication and education. The group with mixed dyspraxia obtained the lowest scores., Conclusions: The achievement of a normal lifestyle by youngsters with DCD is upset in all spheres of life. The impact of DCD on the level of participation of these youngsters is quite significant and affects all lifestyles measured in this study. Children with mixed dyspraxia are particularly affected. These facts must be taken into consideration by anyone involved in the lives of these youngsters., Implications for Rehabilitation: It is necessary to encourage social participation of DCD sufferers aged 5-13 in all spheres of life. Special attention should be paid to those who have a speech disorder. Life habits concerning communication and education may be related; greater efforts should be made to limit the negative impact on other lifestyles. Social participation of DCD sufferers should be measured periodically and appropriate resources must be made available to promote training and support for clinicians. It is important to provide tools to measure social participation for both stakeholders and parents.

This study assessed technology-aided intervention programs for two post-coma men who had re-acquired consciousness, but were unable to engage in personally or socially relevant occupations, given their lack of functional speech and their extensive motor disabilities. The microswitches used for accessing the program contents consisted of (a) a pressure sensor fixed in the palm of the first man's hand that could be activated with a small hand closure movement, and (b) an optic sensor fixed under the chin of the second man that could be activated by mouth opening movements. The programs' content consisted of recreation and communication options, which involved activating music, videos, and basic requests, sending and receiving (listening to) text messages, and placing phone calls. The results showed that the men (a) used the technology-aided programs successfully to manage the recreation and communication options available and (b) showed consistent preference for the sessions with the technology-aided program over other daily events. Family and staff members interviewed about the participants' programs (seven members for each participant) thought that the participants enjoyed the intervention sessions with the programs and that the programs had beneficial effects for them. Implications of the findings are discussed., (Copyright © 2013 Elsevier Ltd. All rights reserved.)

Purpose: The authors designed this investigation to extend the development of a treatment for acquired apraxia of speech (AOS)--sound production treatment (SPT)--by examining the effects of 2 treatment intensities and 2 schedules of practice., Method: The authors used a multiple baseline design across participants and behaviors with 4 speakers with chronic AOS and aphasia. Accuracy of production of trained and untrained words in phrases served as the dependent measure. Participants received 4 permutations of SPT (i.e., intensive-blocked, intensive-random, traditional-blocked, and traditional-random) applied sequentially to different lists of words., Results: Positive changes in accuracy of articulation were observed for all participants for all phases of treatment. Two participants had a slightly poorer response to the traditional-random application of treatment. However, no clinically meaningful differences were noted among treatment applications when follow-up data were considered., Conclusions: Findings from this preliminary Phase II investigation suggest that similar outcomes may be achieved with SPT applied with different treatment intensities and different practice schedules. Extending treatment to achieve higher levels of accuracy may have improved maintenance effects, which may have revealed possible differences among conditions. In addition, overlap in methods used for random and blocked practice may have minimized distinctions between these conditions.

Primary Objective: Research has shown that traumatic brain injury (TBI) can affect a person's ability to perform previously learned skills. Dysexecutive syndrome and inattention, for example, alongside a number of other cognitive and behavioural impairments such as memory loss and lack of motivation, significantly affect day-to-day functioning following TBI. This study examined the efficacy of video modelling in emerging speech in an adult male with TBI caused by an assault., Research Design: In an effort to identify functional relations between this novice intervention and the target behaviour, experimental control was achieved by using within-system research methodology, overcoming difficulties of forming groups for such an highly non-homogeneous population., Methods and Procedures: Across a number of conditions, the participant watched a videotape in which another adult modelled a selection of 19 spoken words. When this modelled behaviour was performed in vivo, then generalization across 76 other words in the absence of a videotape took place., Main Outcomes and Results: It was revealed that video modelling can promote the performance of previously learned behaviours related to speech, but more significantly it can facilitate the generalization of this verbal behaviour across untrained words., Conclusions: Video modelling could well be added within the rehabilitation programmes for this population.

Primary Objective: Children with severe TBI frequently demonstrate language and cognition challenges and require accommodations to succeed academically. However, minimal research exists about accommodation efficacy for this population. This study examined the effect of environmental accommodations (reduced visual and auditory distractions) on the redirections, task variability and accuracy of a child with severe TBI when performing cognitive-linguistic activities., Hypothesis: The researchers hypothesized no differences in variability between accommodation conditions; poorest task performance and most frequent task redirections given no environmental accommodations; comparable task performance and redirections with visual accommodation and auditory accommodation; and highest task performance and fewest redirections with combined visual and auditory accommodations., Research Design: The researchers used an alternating treatment, single case design to compare task performance, variability and redirection averages across conditions. They used visual inspection, linear growth curve analyses and repeated measure analyses for data interpretation., Methods and Procedures: Data collection occurred during label-object association, oral directions and divided attention tasks over 22 sessions varying in accommodation provision., Main Outcomes and Results: Findings showed visual plus auditory accommodations resulted in fewer redirections and superior average performance on all tasks although substantial variability persisted. Significant differences emerged across conditions only for the oral directions task.

Apraxia is a cognitive-motor disorder that impacts the performance of learned, skilled movements. Limb apraxia, which is the topic of this chapter, is specific to disordered movements of the upper limb that cannot be explained by weakness, sensory loss, abnormalities of posture/tone/movement, or a lack of understanding/cooperation. Patients with limb apraxia have deficits in the control or programming of the spatial-temporal organization and sequencing of goal-directed movements. People with limb apraxia can have difficulty manipulating and using tools including cutting with scissors or making a cup of coffee. Two praxis systems have been identified including a production system (action plan and production) and a conceptual system (action knowledge). Dysfunction of the former produces ideomotor apraxia (e.g., difficulty using scissors), and dysfunction of the latter induces ideational apraxia (e.g., difficulty making a cup of coffee). Neural mechanisms, including how to evaluate apraxia, will be presented in the context of these two praxis systems. Information about these praxis systems, including the nature of the disordered limb movement, is important for rehabilitation clinicians to understand for several reasons. First, limb apraxia is a common disorder. It is common in patients who have had a stroke, in neurodegenerative disorders like Alzheimer disease, in traumatic brain injury, and in developmental disorders. Second, limb apraxia has real world consequences. Patients with limb apraxia have difficulty managing activities of daily living. This factor impacts healthcare costs and contributes to increased caregiver burden. Unfortunately, very few treatments have been systematically studied in large numbers of patients with limb apraxia. This overview of limb apraxia should help rehabilitation clinicians to educate patients and caregivers about this debilitating problem, and should facilitate the development of better treatments that could benefit many people in the future., (Copyright © 2013 Elsevier B.V.

Inserm French collective expert's report describes sensory disorders screening. However, the causality link with learning disorders remains questionable. In auditory disorders, there are high-level proof recommendations: early and intensive treatment improves language development, at least partially. For visual disorders, consensus conferences recognize their high frequency in learning disorders but there is no proof of a direct causality link. Currently, in learning disorders, orthoptic treatment is not recommended as a specific therapy. In France, despite medical ignorance about orthoptic assessment, absence of reference values and lack of therapy benefits evaluation, orthoptic treatment is usually prescribed, without any objective criteria. This article makes a literature review concerning the link between learning and sensory disorders. It also describes a typical orthoptic assessment with vision and optic musculature evaluation, and reports its results in a prospective comparative study in three populations (controls, dyslexic and Developmental Coordination Disorders [DCD] children). Strabismus or binocular vision disorders are frequent in DCD. Combined ocular motor function is almost constantly disturbed in DCD (90 %), whereas 34 % of dyslexic children and only 13 % of controls are concerned. Visual disorders are therefore present in learning disorders but also in normal population. Orthoptic assessment results must be interpreted in a multidisciplinary evaluation context., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

This article presents research focused on tracking manual tasks that are applied in cognitive rehabilitation so as to analyze the movements of patients who suffer from Apraxia and Action Disorganization Syndrome (AADS). This kind of patients find executing Activities of Daily Living (ADL) too difficult due to the loss of memory and capacity to carry out sequential tasks or the impossibility of associating different objects with their functions. This contribution is developed from the work of Universidad Politécnica de Madrid and Technical University of Munich in collaboration with The University of Birmingham. The KinectTM for Windows© device is used for this purpose. The data collected is compared to an ultrasonic motion capture system. The results indicate a moderate to strong correlation between signals. They also verify that KinectTM is very suitable and inexpensive. Moreover, it turns out to be a motion-capture system quite easy to implement for kinematics analysis in ADL.

Students with autism display sensory sensitivities to environmental stimuli that affect their attending and engagement in classroom learning activities. The purpose of the study was to determine whether attending of 4 male students, ages 13-20, increased after the installation of sound-absorbing walls and halogen lighting. The multiple single-subject, mixed-method design, AB(B+C), included a 2-wk baseline and two intervention phases: 2 wk after sound-absorbing wall installation using the Owens Corning Basement Finishing System™ (Owens Corning, Toledo, OH) and 2 wk after halogen light installation. We calculated nonattending frequencies from videotaped class sessions and used visual analysis to measure within-phase and between-phase characteristics. Results included increased frequency and stability of attending and engagement and improved classroom performance, comfort, and mood. Journaling provided students' perspective on the modifications and reflected overall increased sensory comfort and themes of improved classroom environment, positive emotional response (mood), and improved classroom performance., (Copyright © 2012 by the American Occupational Therapy Association, Inc.)
