Capener splinting is a common treatment for extension deficit of the proximal interphalangeal (PIP) joint. This study compared the effect of daily splint total end range time (TERT) of 6-12 hr versus 12-16 hr.
Twenty-two participants with extension deficits of the PIP joint were randomly allocated to a daily TERT of 6-12 hr or 12-16 hr. Progress after 8 wk of splinting was evaluated.
No significant difference was found in change in extension range of motion (ROM) between groups (active ROM, F[4, 17] = 2.19, p = .13; passive ROM, F[4, 17] = 0.95, p = .46; torque ROM, F[4, 17] = 1.49, p = .26). Considerable crossover between groups resulted in a similar average daily TERT (9.5 hr for the 6-12 hr group vs. 11.5 hr for the 12-16 hr group).
Further research with a larger sample is needed to determine whether longer daily TERT is beneficial. Our results suggest, however, that most patients find it difficult to wear splints >12 hr/day.
卡彭尔固定夹板是治疗近节指间关节（PIP）伸展不足的常用方法。本研究比较了每天夹板总末端活动时间（TERT）为 6-12 小时与 12-16 小时的效果。
22 名 PIP 关节伸展不足的参与者被随机分配到每天 TERT 为 6-12 小时或 12-16 小时的组中。在夹板治疗 8 周后评估进展情况。
两组间关节活动度（ROM）的变化无显著差异（主动 ROM，F[4, 17] = 2.19，p =.13；被动 ROM，F[4, 17] = 0.95，p =.46；扭矩 ROM，F[4, 17] = 1.49，p =.26）。由于组间大量交叉，导致平均每日 TERT 相似（6-12 小时组为 9.5 小时，12-16 小时组为 11.5 小时）。
需要进一步进行更大样本的研究，以确定更长的每日 TERT 是否有益。然而，我们的结果表明，大多数患者发现很难每天佩戴夹板>12 小时。
