Abstract

Abstract : Background. Stroke causes severe disability, including motor and sensory impairments. We hypothesized that upper limb functional recovery after stroke may be augmented by combining treatments for motor and sensory functions. In order to examine this hypothesis, we conducted a controlled trial on rehabilitation for sensory function to the plegic hand. Methods. The sensory training program consisted of several types of discrimination tasks performed under blind conditions. The sensory training program was performed for 20 min per day, 5 days a week. An experimental group of 31 patients followed this sensory program, while a control group of 25 patients underwent standard rehabilitation. The efficacy of the intervention was evaluated by the tactile-pressure threshold, handgrip strength, and the completion time of manipulating objects. A two-way repeated measures analysis of variance was used to assess interactions between group and time. Moreover, to provide a meaningful analysis for comparisons, effect sizes were calculated using Cohen's d . Results. The mean change in the tactile pressure threshold was significantly larger in the experimental group than in the control group (p < 0.05, d = 0.59 ). Moreover, the completion times to manipulate a middle-sized ball (d = 0.53 ) and small ball (d = 0.80 ) and a small metal disc (d = 0.81 ) in the experimental group were significantly different from those in the control group (p < 0.05 ). Conclusion. The present results suggest that the sensory training program to enhance finger discrimination ability contributes to improvements in not only sensory function but also manual function in stroke patients. The trial is registered with the UMIN Clinical Trials Registry (UMIN000032025 ).
