To define a correct rehabilitation program for neurological patients who have impairment in these skills, there is a need for simple and cost-effective tools to determine which of the visual-motor system levels of organization are compromised by neurological lesions. In their 1995 book, The Visual Brain in Action (Oxford: Oxford University Press), AD Milner and MA Goodale proposed the existence of two pathways for the processing of visual information, the “ventral stream” and “dorsal stream,” that interact in movement planning and programming. Beginning with this model, our study aimed to validate a method to quantify the role of the ventral and dorsal streams in perceptual and visual-motor skills.Subjects and methods: Nineteen right-handed healthy subjects (mean age 22.8 years ± 3.18) with normal or corrected-to-normal vision were recruited. We proposed that a delayed pointing task, a distance reproduction task, and a delayed anti-pointing task could be used to assess the ventral stream, while the dorsal stream could be evaluated with a grasping task and an immediate pointing task. Performance was recorded and processed with the video-analysis software Dartfish ProSuite.Results: Results showed the expected pattern of predominance of attention for the superior left visual field, predominance of the flexor tone in proximal peri-personal space arm movements, tendency toward overestimation of short distances, and underestimation of long distances.Conclusion: We believe that our method is advantageous as it is simple and easily transported, but needs further testing in neurologically compromised patients.Keywords: dorsal stream, ventral stream, visual-motor skills, rehabilitation, neurological disorders

Background: After peripheral facial palsy, the onset of facial synkinesis results in aesthetic disfigurement and local muscle tension or pain, with possible deterioration of patient's well-being and social participation. The availability of valid instruments to evaluate patient-reported severity of facial synkinesis is important to capture the subjective perception of facial impairment., Aim: To generate and validate an Italian version of the Synkinesis Assessment Questionnaire, a patient-reported outcome measure to assess patient-perceived severity of facial synkinesis after peripheral facial palsy., Design: Observational study., Setting: Outpatient clinic of a Rehabilitation Unit., Population: Seventy-five patients with peripheral facial palsy., Methods: Through a process of translation and cross-cultural adaptation, we generated the Italian version of the questionnaire (SAQ-IT) and administered it twice to patients with peripheral facial palsy. We evaluated the clinical severity with the Sunnybrook Facial Grading System (SFGS) and the physical and social/well-being function with the two subscales of the Facial Disability Index (FDI-PHY and FDI-SWB, respectively)., Results: Cronbach's alpha was 0.87. Item-total correlations ranged from 0.30 to 0.70, while inter-item correlations ranged from 0.15 to 0.82, with an average value of 0.48. Test-retest reliability showed an Intraclass Correlation Coefficient of 0.946 (95% confidence interval: 0.916-0.966). The minimum detectable change (with a 95% confidence level, MDC95) was 13.14 points. The correlation between SAQ-IT and the SFGS synkinesis subscore was rho=0.74, while that with the SFGS composite score was rho=0.25, with the FDI-PHY rho=-0.11 and with the FDI-SWB rho=-0.13., Conclusions: Our study validates the SAQ-IT in Italian-speaking individuals with peripheral facial palsy, confirming its acceptable psychometric properties, and providing the MDC95., Clinical Rehabilitation Impact: The availability of a valid instrument for the evaluation of patient-perceived severity of facial synkinesis plays an important role in the definition of tailored rehabilitative interventions after peripheral facial palsy.

This case presentation describes a 47-year-old woman who developed complex regional pain syndrome type II with severe neuropathic pain following iatrogenic transection of the tibial nerve at the ankle. The pain and disability progressively worsened over time, markedly impaired ambulation, and were not relieved despite various analgesic treatments. After injection of botulinum toxin (abobotulinumtoxinA, BoNT-A) in the leg muscles the tendons of which pass through the tarsal tunnel (together with the tibial nerve), her pain decreased and her walking capacity improved. This case suggests a new therapeutic role for botulin toxin in treating peripheral neuropathic pain caused by movement-evoked ectopic potentials., Level of Evidence: V., (Copyright © 2017 American Academy of Physical Medicine and Rehabilitation.

Background: Only few studies have considered the effects of the combined treatment with onabotulinumtoxinA (BoNT-A) injections and biofeedback (BFB) rehabilitation in the recovery of postparetic facial synkinesis (PPFS)., Aim: To explore the presence of a persistent improvement in facial function out of the pharmacological effect of BoNT-A in subjects with established PPFS, after repeated sessions of BoNT-A injections combined with an educational facial training program using mirror biofeedback (BFB) exercises. Secondary objective was to investigate the trend of the presumed persistent improvement., Study Design: Case-series study., Setting: Outpatient Clinic of Physical Medicine and Rehabilitation Unit., Population: Twenty-seven patients (22 females; mean age 45±16 years) affected by an established peripheral facial palsy, treated with a minimum of three BoNT-A injections in association with mirror BFB rehabilitation. The interval between consecutive BoNT-A injections was at least five months., Methods: At baseline and before every BoNT-A injection+mirror BFB session (when the effect of the previous BoNT-A injection had vanished), patients were assessed with the Italian version of Sunnybrook Facial Grading System (SB). The statistical analysis considered SB composite and partial scores before each treatment session compared to the baseline scores., Results: A significant improvement of the SB composite and partial scores was observed until the fourth session. Considering the "Symmetry of Voluntary Movement" partial score, the main improvement was observed in the muscles of the lower part of the face., Conclusions: In a chronic stage of postparetic facial synkinesis, patients may benefit from a combined therapy with repeated BoNT-A injections and an educational facial training program with mirror BFB exercises, gaining an improvement of the facial function up to the fourth session. This improvement reflects the acquired ability to use facial muscle correctly. It doesn't involve the injected muscles but those trained with mirror biofeedback exercises and it persists also when BoNT-A action has vanished., Clinical Rehabilitation Impact: The combined therapy with repeated BoNT-A injections and an educational facial training program using mirror BFB exercises may be useful in the motor recovery of the muscles of the lower part of the face not injected but trained.

Pain may affect all aspects of social life and reduce the quality of life. Neuropathic pain (NP) is common in patients affected by plexopathy, radiculopathy, mononeuropathy, peripheral neuropathy. Phantom limb pain (PLP) is a painful sensation that is common after amputation, and its pathophysiological mechanisms involve changes in the peripheral and central nervous system. Given the lack of conclusive evidence and specific guidelines on these topics, the aim of the Italian Consensus Conference on Pain on Neurorehabilitation (ICCPN) was to collect evidence and offer recommendations to answer currently open questions on the assessment and treatment of NP associated with the above conditions and PLP. When no evidence was available, recommendations were based on consensus between expert opinions. Current guidelines on the assessment and pharmacological treatment of NP can be applied to plexopathy, radiculopathy, mononeuropathy, peripheral neuropathy, while evidence for invasive treatments and physical therapy is generally poor because of the low quality of studies. Treatment of PLP is still unsatisfactory. Data on the functional outcome and impact of pain on neurorehabilitation outcome in these conditions are lacking. In most cases, a multidisciplinary approach is recommended to offer a better outcome and reduce side effects. High quality studies are requested to address the unmet needs in this field.

Background: Aging has a recognized degenerative effect on the functionality of the hand in terms of strength and dexterity. Despite this, there are few studies in literature that quantify the upper limb skills in the elderly., Aim: The aim was to present quantitative data regarding upper limb functionality in the elderly and to quantify the effect of aging on them, considering the influence of the comorbidities, of the global level of autonomy, of the cognitive status and of the mood, which are typically compromised in the elderly., Design: It was a controlled study., Setting: It was settled in the Rehabilitation Unit of the "Santa Maria alle Fonti" Medical Center, part of the Don Carlo Gnocchi ONLUS Foundation., Population: Thirty-five elderly inpatients (aged 78.6±7.5 years) compared to 30 healthy young adults (aged 30±3.9 years)., Methods: A task consisting in 12 trials of grasping of rulers was administered to each subject and studied with a video analysis software. To assess the comorbidities, the global level of autonomy, the cognitive status and the mood, we respectively used the Cumulative Illness Rating Scale (CIRS), the Functional Independence Measure (FIM™), the Mini Mental State Examination (MMSE) and the Geriatric Depression Scale in the 15-items version (GDS-15). The scores obtained in these scales were correlated to the mean times of trials execution., Results: The motor performance was significantly worse in the inpatients group compared to the control group in terms of time to complete single tasks (which was on average three times higher in the inpatients group) and of respect of the starting sound stimulus, with more subjects from the inpatients group anticipating the starting signal. This worsening of the motor performance was significantly correlated to the severity of comorbidities and to the global level of autonomy. No significant differences emerged for the correctness of the performance and significant differences were not correlated with depression or cognitive impairment., Conclusion: This study provides quantifiable data regarding upper limb skills in the elderly inpatient, allowing comparisons with other future studies of the rehabilitative environment., Clinical Rehabilitation Impact: It suggests the relevance of considering the severity of comorbidities and the global level of autonomy in the assessment of upper limb skills in the elderly.

Background: An increased weight of the breasts causes several spinal postural alterations that reduce the ability to perform dynamic tasks requiring a stable balance. The effects of the increased weight of the breasts on static posture after implant breast augmentation have not been investigated yet., Methods: Forty volunteer healthy women were asked to wear different sized breast implants (800, 400, and 300 g) inside a dedicated sports bra for 6½ consecutive hours during their everyday life activities, 1 day for every implant size. Posture changes were assessed with the association of a physiatric clinical examination with a static force platform analysis., Results: A significant increase in cervical lordosis after the use of 400-g breast implants and upward was demonstrated. This alteration was stable between the 400-g and 800-g breast implants. The 400-g (per breast) implant might therefore be the load threshold that breaks the cervical postural physiologic balance. A significant increase in lumbar lordosis was demonstrated only after the use of the 800-g breast implants. The static force platform assessment demonstrated a worsening of the balance independent from the visual control with the use of 400-g and 800-g implants., Conclusions: Heavy breast implants proved to induce reversible alterations in the spinal curve, and 400 g is the cutoff for functional physiologic compensation in the short term. Such a weight might be considered the safety limit for the use of breast implants for cosmetic purposes.

Although the diagnosis of and therapy for acute disseminated encephalomyelitis (ADEM) have been extensively investigated, the role of rehabilitation in modifying its functional outcome has received little attention in the literature so far. We report a case of pediatric ADEM who showed complete functional recovery following early rehabilitative treatment, started in the Intensive Care Unit.

Objective: To investigate the analgesic effect of high-frequency transcutaneous peripheral nerve stimulation (HF-TPNS) in the ipsilateral and contralateral skin territory of the stimulated nerve., Design: Prospective, cross-over study., Setting: Clinical neurophysiology unit, institutional care, rehabilitation center., Participants: Ten healthy volunteers (5 male, 5 female)., Methods: Participants underwent 3 different sessions. In the first, heat pain thresholds (HPTs) were measured on the left dorsal hand skin without stimulation; in the second and third sessions, HPTs were measured, respectively, in the territory of the left and right radial nerve before, during, and after an electrical stimulation (10 minutes, 100 Hz, 0.1 ms) of the left superficial radial nerve., Main Outcome Measurement: Heat pain threshold., Results: An increase of HPTs was observed in the skin territory of both right and left radial nerve during and after the left radial nerve stimulation., Conclusion: The present study demonstrates an analgesic effect of HF-TPNS not only in the ipsilateral but also in the contralateral side of stimulation, suggesting a possible role of contralateral HF-TPNS in the treatment by physical therapy of patients with unilateral pain syndromes., (Copyright © 2015 American Academy of Physical Medicine and Rehabilitation.

Objectives/hypothesis: Facial synkinesis is a well-known disabling occurrence following severe facial palsy. Platysma muscle, innervated by the facial nerve, can be involved in synkinesis as well, but thus far has been little investigated. The aim of our study is to evaluate the presence of platysma synkinesis and its clinical evolution after onabotulinumtoxinA (BoNT-A) (Botox(®) ; Allergan Pharmaceuticals, Irvine, CA) injections., Study Design: Retrospective study., Methods: Sixty-nine patients were treated for synkinesis following facial palsy. Of those, 45 were affected by platysma synkinesis and thus were injected in the platysma muscle. The total number of sessions was 124. The Sunnybrook Facial Grading System (SFGS) and a specific platysmal evaluation for the presence and severity of synkinesis and local symptoms were performed before and after BoNT-A treatments., Results: Platysma synkinesis was present in 65.2% of the sample and was associated with subjective complaints in 85.5% of the cases. The facial expressions more related to platysma synkinesis were snarl, followed by open-mouth smile and lip pucker. After each BoNT-A treatment, there was an improvement in facial symmetry at rest and during voluntary movements, a global reduction of synkinesis, and a specific reduction of synkinesis and symptoms related to the platysma. No adverse reaction to BoNT-A occurred., Conclusion: Platysma involvement represents a recurring and symptomatic problem in patients affected by synkinetic recovery following facial palsy. After BoNT-A injections, there is a reduction in platysma synkinesis and related symptoms., Level of Evidence: 4., (© 2014 The American Laryngological, Rhinological and Otological Society, Inc.)
