We recently completed a pilot study of a modified form of CI therapy for stroke survivors with plegic hands, and obtained surprisingly positive findings. Six individuals were enrolled who had a flicker of active movement at the elbow and at the wrist or a finger and 30° of active range of motion at the shoulder. Participants received three weeks of CI therapy, combined with other modes of therapy, for six hours per day. The treatment package included tone management/movement facilitation, training of more-impaired arm use using shaping, functional task practice, restraint of the less-impaired arm in the laboratory and at home as indicated, and a package of behavioral methods for transferring gains from the laboratory to the home situation. As a group, the patients showed a large improvement in more-impaired arm use in daily life after treatment (Motor Activity Log or MAL; p's < 05, Effect Size > 1.5). Improvements in more-impaired arm motor ability, as measured by scores on a laboratory motor performance test (graded Wolf Motor Function Test; gWMFT) and standardized clinical examination (Fugl-Meyer), were also substantial (p's < .05).
