Development and feasibility of first- and third-person motor imagery for people with stroke living in the community.

BACKGROUND: Impairment of arm movement occurs in up to 85% of people post-stroke, affecting daily living activities, and quality of life. Mental imagery effectively enhances hand and daily function in people with stroke. Imagery can be performed when people imagine themselves completing the movement or imagine another person doing it. However, there is no report on the specific use of first-person and third-person imagery in stroke rehabilitation. AIMS: To develop and assess the feasibility of the First-Person Mental Imagery (FPMI) and the Third-Person Mental Imagery (TPMI) programs to address the hand function of people with stroke living in the community. METHODS: This study comprises phase 1-development of the FPMI and TPMI programs, and phase 2-pilot-testing of the intervention programs. The two programs were developed from existing literature and reviewed by an expert panel. Six participants with stroke, living in the community, participated in the pilot-testing of the FPMI and TPMI programs for 2 weeks. Feedback collected included the suitability of the eligibility criteria, therapist's and participant's adherence to intervention and instructions, appropriateness of the outcome measures, and completion of the intervention sessions within the specified time. RESULTS: The FPMI and TPMI programs were developed based on previously established programs and included 12 hand tasks. The participants completed four 45-min sessions in 2 weeks. The treating therapist adhered to the program protocol and completed all the steps within the specified time frame. All hand tasks were suitable for adults with stroke. Participants followed the instructions given and engaged in imagery. The outcome measures selected were appropriate for the participants. Both programs showed a positive trend towards improvement in participants' upper extremity and hand function and self-perceived performance in activities of daily living. CONCLUSIONS: The study provides preliminary evidence that these programs and outcome measures are feasible for implementation with adults with stroke living in the community. This study outlines a realistic plan for future trials in relation to participant recruitment, training of therapists on the intervention delivery, and the use of outcome measures.

The Activation of the Mirror Neuron System during Action Observation and Action Execution with Mirror Visual Feedback in Stroke: A Systematic Review.

Objective: To evaluate the concurrent and training effects of action observation (AO) and action execution with mirror visual feedback (MVF) on the activation of the mirror neuron system (MNS) and its relationship with the activation of the motor cortex in stroke individuals. Methods: A literature search using CINAHL, PubMed, PsycINFO, Medline, Web of Science, and SCOPUS to find relevant studies was performed. Results: A total of 19 articles were included. Two functional magnetic resonance imaging (fMRI) studies reported that MVF could activate the ipsilesional primary motor cortex as well as the MNS in stroke individuals, whereas two other fMRI studies found that the MNS was not activated by MVF in stroke individuals. Two clinical trials reported that long-term action execution with MVF induced a shift of activation toward the ipsilesional hemisphere. Five fMRI studies showed that AO activated the MNS, of which, three found the activation of movement-related areas. Five electroencephalography (EEG) studies demonstrated that AO or MVF enhanced mu suppression over the sensorimotor cortex. Conclusions: MVF may contribute to stroke recovery by revising the interhemispheric imbalance caused by stroke due to the activation of the MNS. AO may also promote motor relearning in stroke individuals by activating the MNS and motor cortex.

Development and initial validity of the in-hand manipulation assessment.

BACKGROUND/AIM: A review of the literature related to in-hand manipulation (IHM) revealed that there is no assessment which specifically measures this construct in the adult population. This study reports the face and content validity of an IHM assessment for adults with impaired hand function based on expert opinion. METHODS: The definition of IHM skills, assessment tasks and scoring methods identified from literature was discussed in a focus group (n = 4) to establish face validity. An expert panel (n = 16) reviewed the content validity of the proposed assessment; evaluating the representativeness and relevance of encompassing the IHM skills in the proposed assessment tasks, the clarity and importance to daily life of the task and the clarity and applicability to clinical environment of the scoring method. The content validity was calculated using the content validity index for both the individual task and all tasks together (I-CVI and S-CVI). Feedback was incorporated to create the assessment. RESULTS: The focus group members agreed to include 10 assessment tasks that covered all IHM skills. In the expert panel review, all tasks received an I-CVI above 0.78 and S-CVI above 0.80 in representativeness and relevance ratings, representing good content validity. With the comments from the expert panel, tasks were modified to improve the clarity and importance to daily life. A four-point Likert scale was identified for assessing both the completion of the assessment tasks and the quality of IHM skills within the task performance. CONCLUSION: Face and content validity were established in this new IHM assessment. Further studies to examine psychometric properties and use within clinical practice are recommended.

Wheelchair accessibility of public buildings: a review of the literature.

PURPOSE: The purpose of this review was to examine the wheelchair accessibility in public buildings and discuss the role of professional in this practice area. METHOD: Of the 85 originally identified publications from a search of major electronic bibliographic databases, 12 studies relating to wheelchair accessibility in public buildings were selected. The compliance rates with wheelchair accessibility in different areas were summarised. RESULTS: No study reported 100% wheelchair accessibility despite the enforcement of existing laws and regulations. Parking had the lowest compliance rate among all facilities in terms of accessibility, while entrances had the highest. CONCLUSIONS: A global review is needed of both new and old buildings regarding wheelchair accessibility. Professional in this practice area has an important role to play in advocating wheelchair accessibility and assisting wheelchair users to participate fully in all areas of the community.
