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.)

This case report describes an intensive approach to treating autism and provides an intersection between a first-person narrative paired with intervention and outcomes. In-depth conversations between a person with autism and an occupational therapist provide insight into understanding differences and difficulties in sensory processing and regulation, praxis, and communication. Individuals with autism may be intellectually and emotionally intact but hampered by deficits that interfere with the ability to move the body efficiently. These sensorimotor deficits underlie the ability to communicate with others and to develop relationships. This article illustrates the benefits of an intensive therapeutic program designed to address sensory and motor differences underlying communication, as well as the vital role the occupational therapist plays in addressing these underlying differences to improve functional communication and social participation.

Objectives: The purpose of this study was to determine whether persons with developmental dyspraxia and apraxia make similar errors during the performance of four types of tasks., Method: Three groups of subjects with dyspraxia or apraxia (i.e., children with learning disabilities and dyspraxia, young adults with learning disabilities and dyspraxia, older adults with left-hemisphere brain damage with apraxia) and three groups of age-matched control subjects (i.e., children, young adults, older adults) were observed performing transitive, intransitive, verbal command, and imitation tasks. Performance was scored on the basis of the types of errors made. Errors were classified as conceptual (nonrelated, unrecognizable, sequencing) or production (omission, perseveration, related, internal configuration, external configuration, incorrect movement, body part as object)., Results: No significant difference was found between conceptual and production error patterns for any group. In addition, there was no significant difference between the dyspraxia and apraxia groups or among the control groups on the specific types of production errors made. However, the dyspraxia and apraxia groups differed in the type of conceptual error made on the intransitive task. The body-part-as-object error was the most frequently made error on the transitive, verbal command, and imitation tasks, whereas the movement error was the most frequently made error on the intransitive task., Conclusion: Subjects with dyspraxia or apraxia make similar errors, suggesting that the praxis behaviors are similar.

Objectives: The purpose of this study was to examine the performance of persons with right cerebrovascular accident (RCVA) and persons with left cerebrovascular accident (LCVA) on a variety of measures of praxis and visual perception in order to examine the relative contributions of the left and right cerebral hemispheres to praxis and perception., Methods: Forty-five subjects, 15 with RCVA, 15 with LCVA, and 15 without CVA (control subjects), were tested on three tests of praxis-praxic production, gesture comprehension, and gesture discrimination-and selected tests of visual perception, including the Judgement of Line Orientation Test, the Motor Free Visual Perception Test, the Hooper Visual Organization Test, and the Line Bisection Test., Results: Subjects in both groups with CVA performed more poorly on all of the tests than did control subjects. The group with LCVA performed most poorly on tests of gesture comprehension and praxis production, whereas the group with RCVA performed most poorly on tests of gesture discrimination and visual perception., Conclusion: These findings suggest that both the right and left cerebral hemispheres contribute to different aspects of praxis. Elements of visual perception may be related to gesture comprehension, gesture discrimination, and praxis production in adults who have had stroke. These findings have clinical implications regarding instructional style and perceptual and praxic training.

Objectives: Treatment protocols derived from research literature can help therapists provide more rigorous treatment and more systematic assessment of client progress., Method: This study applied research findings about the influence of task, subject, and feedback parameters on adult performance with block designs to an occupational therapy treatment protocol for parquetry block assembly--an activity occupational therapists use to remediate constructional deficits. Task parameter research suggests that parquetry tasks can be graded according to the features of the design cards, with cards having all block boundaries drawn in being easier than those with some block boundaries omitted., Results: Subject parameter findings suggest that clients' lesions and initial constructional competence can influence their approaches to parquetry tasks., Conclusion: Feedback parameter research suggests that a combination of perceptual and planning cues is most effective for parquetry tasks. Methods to help clients transfer constructional skills from parquetry to functional tasks are also discussed.

Object manipulation skills are a vital area for client assessment in occupational therapy, but in-hand manipulation skills are not specifically included in any standardized tests of hand function for children. The In-Hand Manipulation Test (IMT) was developed for use by occupational therapists with preschool and young school-age children. Assessment of the IMT's content validity was an important precursor to further development of the test. Twenty-four certified occupational therapists rated young children's performance during administration of the IMT before completing a content validity survey about the test. Overall, the IMT's content validity was supported by the feedback from the raters. A final test length of 50 items with two trials per item was considered acceptable, provided that the test takes no longer than 20 to 30 min to administer. The therapists were positive about the content and structure of the rating scale and the approach used in presenting activities to the children. Some issues related to functional validity of some skills or the proportions of in-hand manipulation skills were raised. Further development of the IMT for clinical and research use seems warranted. Revisions to the test will be made, and another pilot study will be conducted before normative data collection. Training for administering and scoring the test will incorporate the recommendations on the basis of this study's results.

This paper introduces a practice model based on the occupational adaptation frame of reference (Schkade & Schultz, 1992). The occupational adaptation practice model emphasizes the creation of a therapeutic climate, the use of occupational activity, and the importance of relative mastery. Practice based on occupational adaptation differs from treatment that focuses on acquisition of functional skills because the practice model directs occupational therapy interventions toward the patient's internal processes and how such processes are facilitated to improve occupational functioning. The occupational adaptation practice model is holistic. The patient's occupational environments (as influenced by physical, social, and cultural properties) are as important as the patient's sensorimotor, cognitive, and psychosocial functioning and the patient's experience of personal limitations and potential is validated. The integration of these concepts drives the treatment process. Through a description of treatment with a variety of patients, this paper presents the model's diversity and illustrates the relationship between the concepts. The occupational adaptation practice model reflects the uniqueness of occupational therapy and integrates the profession's historical practice with contemporary interventions and methods.

This study was designed to obtain a detailed picture of the fine motor requirements in regular elementary school classrooms. This knowledge is critical for occupational therapists in working with children with fine motor and handwriting problems who are main-streamed into regular classes. The allocation of time to fine motor activities and the types of fine motor tasks children are expected to perform in elementary school were investigated through the observation of six elementary school classrooms. A written minute-by-minute record of one whole day's activities in each classroom showed that 30% to 60% of the day was allocated to fine motor activities, with writing tasks predominating over other manipulative tasks. Implications for children with fine motor difficulties include the need for modifications to volume of work, types of tasks, and materials.
