Orthoses that are used to stabilize, protect, and support the wrist during functional activities often interfere with normal movement and, therefore, with hand function. This study compared the manual dexterity and grip strength of 20 female subjects while using a free hand and while wearing each of four wrist extensor orthoses: a Futuro prefabricated wrist brace (No. 33), a volar thumbhole orthosis, a volar orthosis with a radial connector bar, and a dorsal orthosis with distal transverse arch support. Of these orthoses, the Futuro prefabricated wrist brace afforded the best overall dexterity, although it was significantly slower (p less than .05) than the other orthoses in a writing subtest. Of the custom-made orthoses, the volar style with radial connector bar afforded the best overall dexterity. All of the orthoses significantly (p less than .01) reduced grip strength. The Futuro prefabricated wrist brace afforded the strongest grip strength of the four orthoses studied, and the volar thumbhole orthosis permitted the strongest grip among the custom-made orthotic styles.
在功能活动期间用于稳定、保护和支撑手腕的矫形器常常会干扰正常运动，进而影响手部功能。本研究比较了20名女性受试者在徒手以及佩戴四种腕伸肌矫形器（一种Futuro预制腕部支具（33号）、一种掌侧拇指孔矫形器、一种带有桡侧连接杆的掌侧矫形器以及一种带有远端横向弓支撑的背侧矫形器）中的手部灵巧性和握力。在这些矫形器中，Futuro预制腕部支具总体灵巧性最佳，不过在一项书写子测试中，其速度明显慢于其他矫形器（p小于0.05）。在定制矫形器中，带有桡侧连接杆的掌侧款式总体灵巧性最佳。所有矫形器均显著降低了握力（p小于0.01）。在研究的四种矫形器中，Futuro预制腕部支具握力最强，在定制矫形器款式中，掌侧拇指孔矫形器握力最强。
