Study compared the outcome of robot assisted therapy with dose-matched active control therapy by using accelerometers to study functional recovery in chronic stroke patients. Participants were 20 patients with chronic stroke and a mean age of 55 years, 7 of whom were women. Participants were divided into two 10-member groups to receive either robot assisted or dose-matched active control therapy for 90 to 105 minutes a day, 5 days a week, for 4 weeks. The robot assisted group practiced with the Bi-Manu-Track robotic arm trainer, which enabled bilateral mirror-like movement cycles consisting of forearm pronation-supination and wrist flexion-extension in robot-controlled, passive-active, and resistance modes. The functional tasks practiced in the control group were activities of daily living such as picking up a telephone receiver, pulling out a drawer, and opening a jar. Outcome measures included arm activity ratio, that is the ratio of mean activity between the impaired and unimpaired arm; and scores on the Fugl-Meyer Assessment Scale, Functional Independence Measure, Motor Activity Log, and ABILHAND questionnaire. The robot assisted therapy group significantly increased motor function, hemiplegic arm activity, and bilateral arm coordination compared with the dose-matched active control group. Study limitations and implications for future research are discussed.
