    Abstract:
    BACKGROUND: Sensory amplitude electrical stimulation (SES) and repetitive task practice reduce impairments and arm dysfunction when delivered separately following stroke. OBJECTIVE: To determine if home-based, task-specific arm exercise was more effective when administered concurrent with SES. METHODS: Thirty-eight subjects with chronic stroke and mean Fugl-Meyer Assessment (FMA) score 28/66 (15-45) participated. Subjects were randomly assigned to an SES (n = 20) or sham stimulation (n = 18) group. Subjects engaged in task-based home exercise for 30 minutes, twice daily, for four weeks while wearing a glove electrode on the impaired hand. Experimental subjects received SES while control subjects received sham stimulation during exercise. PRIMARY OUTCOME MEASURES: FMA and Arm Motor Ability Test (AMAT). RESULTS: There were no significant between-group differences for outcome measures. There was a significant difference between the pre- and post-test scores in the SES group AMAT median time (P = 0.003 95% confidence interval (CI): -14.304, -6.365; effect size: 0.84). Practice time was not associated with changes in outcomes. Subjects with more sensorimotor dysfunction had significantly greater improvements on AMAT median time (P = 0.037). There was a significant relationship between baseline FMA score and FMA change score (r = 0.402; P = 0.006). CONCLUSIONS: This study describes a unique SES delivery system via glove electrode that enabled delivery of SES during home-based arm task practice in stroke survivors. Task practice with concurrent SES did not demonstrate significantly better effects than task practice with sham stimulation, however there was a trend for greater improvement in one activity measure.
