The study was a retrospective cohort analysis for a 19-month period from May 2013 to December 2014.
Although the use of orthoses has long been a staple of conservative treatment measures for individuals with osteoarthritis of the thumb carpometacarpal (CMC) joint, there remains little evidence exploring its effectiveness in improving functional outcomes for this client population.
The purpose of this study was to assess the effectiveness of 3 frequently used orthoses in improving the functional pinch strength of adults with a diagnosis of thumb CMC joint osteoarthritis.
A retrospective cohort analysis was conducted to determine whether pinch strength improved after orthotic fabrication, and fitting in patients referred to a hand therapy clinic.
Patients who received a Colditz design orthosis had a mean increase of 2.64 lb with regard to functional pinch strength after orthotic fabrication and fitting. Patients who received a Comfort Cool orthosis (North Coast Medical, Morgan Hill, CA) had a mean increase of 2.47 lb, whereas patients who received a Thumb Spica orthosis had a mean increase of 3.25 lb. There was no evidence of any statistically significant difference in the average improvements in pinch strength between the Colditz design orthosis and the Comfort Cool orthosis.
Results from this study demonstrate that orthosis wear consistently increases the functional pinch strength of individuals with thumb CMC joint osteoarthritis. Large-scale multisite research studies comparing various orthotic designs are necessary to help therapists determine best practice interventions for the conservative management of thumb CMC joint osteoarthritis.

本研究是一项回顾性队列分析，研究时间为2013年5月至2014年12月的19个月期间。
尽管长期以来，矫形器一直是拇指腕掌（CMC）关节骨关节炎患者保守治疗措施的主要手段，但几乎没有证据探讨其对改善该患者群体功能结局的有效性。
本研究的目的是评估3种常用矫形器对改善诊断为拇指CMC关节骨关节炎的成年人功能性捏力的有效性。
进行回顾性队列分析，以确定在手部治疗诊所接受矫形器制作和装配后，捏力是否有所改善。
接受Colditz设计矫形器的患者在矫形器制作和装配后，功能性捏力平均增加2.64磅。接受Comfort Cool矫形器（加利福尼亚州摩根希尔市北海岸医疗公司）的患者平均增加2.47磅，而接受拇指支具矫形器的患者平均增加3.25磅。没有证据表明Colditz设计矫形器和Comfort Cool矫形器在捏力平均改善方面存在任何统计学上的显著差异。
本研究结果表明，佩戴矫形器可持续提高拇指CMC关节骨关节炎患者的功能性捏力。有必要开展大规模多中心研究，比较各种矫形器设计，以帮助治疗师确定拇指CMC关节骨关节炎保守治疗的最佳实践干预措施。
