Abstract

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.
