The Effect of Different Types of Resting Hand Splints on Spasticity and Hand Function among Patients with Stroke

After stroke, these changes consequently result in the limitation of upper limb joint range of motion or muscle shortening, and spasticity, causing the reduction of hand functions. This study aimed to investigate the effect according to the types of resting hand splints, particularly the effect of the application of resting hand splint. This study was performed in two groups, which were determined by random assignment according to the order of visits of 52 subjects who were diagnosed of stroke. The patients were divided into a dorsal resting hand splint group (n=26) and volar resting hand splint group (n=26). The data collected in this study was analyzed using SPSS version 18.0.For the difference in Modified Ashworth Scales (MAS), surface ElectroMyoGraphy (sEMG), and Wrist Active Range of Motion(AROM) before and after the intervention in two groups, paired t-test was performed, and independent sample t-test was performed to compare the change(s) before and after the intervention in two groups. Statistical significance level was α=.05. First, there was a significant difference in wrist MAS, AROM, and sEMG in the group of dorsal resting hand splint. Second, there was no significant difference in wrist MAS and AROM in the group of volar resting hand splint, but there was a significant difference in wrist sEMG. Third, there was a significant difference in wrist MAS and AROM in the group of resting dorsal hand splint as a result of comparing change(s) between two groups, but there was no significant difference in wrist sEMG. Through this study, it was found that dorsal resting hand splint was more effective in the reduction of wrist spasticity and improving AROM than volar resting hand splint in stroke patients. Applying resting hand splint to stroke patients would not only have preventive effects but also have great influence on the improvement of hand function.
