| Popis: | 94 The aim of this paper is to examine the splints effect on hand performances. Five experiments are designed to evaluate hand blood flow, grip/pinch strength and corresponding EMG, typing performance, dexterity, the range of wrist motion (ulnar/radial deviation, flexion/extension), respectively. All adopted a nested-factorial design, and the factors included gender, subject (nested within the gender), and splint-condition (bared and 3 types of splints). One of the three types of splints does not have a volar part (named ‘wrist’), but the other two have (named ‘Volar-1’ and ‘Volar-2’, respectively). The Results indicate that wearing splints is able to block the blood flow and results in a greater blood volume pulse (BVP) on the hand. Furthermore, wearing Volar-1 and Volar-2 splints diminish the grip strength, but wearing ‘Wrist’ splint does not. Even wearing splints influences the pinch strength, but the range is not greater than 0.3 kg. Meanwhile, wearing splints changes the EMG significantly. In addition, wearing splints reduces typing velocity, the hand dexterity as well as the range of wrist motion. For gender effect, males have greater grip/pinch strength, less dexterity and range of motion. Finally, females have greater subjective perception of discomfort than males do. |
