Objectives: This study was designed to determine the effects of Volar-Dorsal Wrist/Hand Immobilization Splint on upper extremity motor components and function of stroke patients.

Methods: fourteen patients were participated in this study. The patients were selected based on the inclusion and exclusion criteria, and were given the splint after a primary evaluation. They were re-evaluated after one, two and three months. In order to assess spasticity, the range of motion, and upper extremity function, the Modified Ashworth Scale (MAS), the goniometry, and fugl-meyer assessment were used respectively. The splints were used 2 hours during the day and the whole night in three months.

Results: The amount of the upper extremity function changes (P(v)=0.07) was not significant: and the amount of the ranges of the motion changes (P(v)=0.02) were statistically significant. The changes in range of  motion of other joints and spasticity were not significant (P(v)>.05).

Discussion: The results of the present study indicated that, volar-dorsal wrist/hand immobilization splints can improve the AROM of metha-carpophalengeal joints. Although spasticity, the range of motion of other joints, and the upper extremity function went through some changes due to  splinting (3month), these changes were not significant, which requires further research.
