Description
Summary:We describe the development and three case reports of a home-based intervention for children with hand hemiplegia that integrates custom video games with contralaterally controlled functional electrical stimulation (CCFES). With CCFES, stimulated opening of the more-affected hand is modulated by volitional opening of the less-affected hand. Video games that solicit goal-oriented, skill-requiring movement have shown promise for treating hemiplegia, but they have not previously been combined with electrical stimulation in children. Three children ages 8, 9, and 11 with moderate-to-severe hand hemiplegia were assigned six weeks of therapy in lab and at home. The goal was to determine if children could tolerate 9 lab treatment sessions and administer up to 7.5 hrs/wk of CCFES video game therapy at home. The feasibility of this intervention for home use was assessed by device logs, end-of-treatment interviews, and motor function/impairment assessments. With caregiver help, the children were all able to attend 9 lab sessions and built up to 7.5 hrs/wk of therapy by week 3. They averaged 5-7 hrs/wk of home intervention overall. Motor outcomes improved for all three participants at treatment end, but mostly regressed at 4-weeks follow-up. Individual improvements at treatment end exceeded minimum detectable or clinically important thresholds for Assisting Hands Assessment, Fugl-Meyer Assessment, and Melbourne Motor Assessment 2. We found preliminary indications that CCFES-integrated video game therapy can provide a high dose of hand motor control therapy at home and in the lab. Improvements in motor outcomes were also observed, but more development and study is needed.
