The purpose of this study was to evaluate the efficacy of custom thermoplastic splinting designed to limit metacarpalphalangeal (MCP) joint flexion for trigger finger as a first treatment option. This study was a single group, prepost design with 28 participants fit with a low-profile custom thermoplastic MCP blocking (ring) splint. The pre- and post outcome measures included: stages of stenosing tenosynovitis (SST), grip strength, Numeric Pain Rating Scale (NPRS), the number of triggering events in ten active fists, and participant perceived improvement in symptoms. These measures were taken at the time of initial assessment before splint fabrication and after six weeks of continuous splint wear. Participants were given an educational handout on trigger finger and exercises to complete independently. After the use of a splint, there were statistically significant improvements in the SST, NPRS, the number of triggering events in ten active fists, and in the participant perceived improvement in symptoms. Grip strength did not significantly change. This study demonstrated a benefit from the use of a custom thermoplastic splint for an isolated incidence of trigger finger based on chosen outcome measures.
本研究的目的是评估定制热塑性夹板作为扳机指的首选治疗方案，限制掌指（MCP）关节屈曲的疗效。本研究为单组前后对照设计，28名参与者佩戴了低轮廓定制热塑性MCP阻挡（环形）夹板。前后评估指标包括：狭窄性腱鞘炎（SST）分期、握力、数字疼痛评分量表（NPRS）、十个主动握拳时的扳机事件数量，以及参与者自我感觉的症状改善情况。这些指标在夹板制作前的初始评估时以及连续佩戴夹板六周后进行测量。参与者收到了一份关于扳机指的教育手册，并需独立完成相关练习。使用夹板后，SST、NPRS、十个主动握拳时的扳机事件数量以及参与者自我感觉的症状改善情况均有统计学意义上的显著改善。握力没有显著变化。基于所选评估指标，本研究证明了使用定制热塑性夹板治疗单发扳机指的益处。
