Abstract

Background

Improving proprioception can reduce the risk of injuries, while its disruption may lead to injuries and recurrent or persistent symptoms.

Purpose

This study aimed to evaluate the immediate effects of elbow orthoses on elbow proprioception in asymptomatic individuals.

Study Design

This was a randomized, controlled, single-blinded study with a sham application.

Methods

Sixty participants were equally distributed into three orthosis groups (counterforce, sleeve, and sham). Proprioception was assessed using active joint position sense error (JPSE) at 70° and 110° of elbow flexion at three time points: baseline (BS), immediately after (IA) wearing the orthosis, and 30 minutes after (30MA) wearing the orthosis.

Results

Between groups: No significant difference in JPSE was observed at 70° (p = 0.095); however, there was a significant difference at 110° (p = 0.005).

Between time points: At 70°, JPSE did not exhibit a significant difference (p = 0.055), whereas a significant difference was observed at 110° (p = 0.020).

Interaction of time points×groups: No significant interaction was observed either at 70° (p = 0.476) or at 110° (p = 0.346).

At 70°, within the sleeve group, significant differences were identified between BS-30MA (p = 0.001) and IA-30MA (p = 0.009).

At 110°, in the sleeve group, significant differences were observed between BS-30MA (p = 0.007) and IA-30MA (p = 0.007).

In the counterforce group, significant differences were identified between BS-30MA time points (p = 0.001).

At 70°, no difference was observed within the overall evaluation in the counterforce group (p > 0.05), whereas at 110°, a significant difference was noted (p = 0.026).

At both 70° and 110°, no differences were identified within the overall evaluation in the sleeve and sham groups (p > 0.05).

Conclusions

In asymptomatic individuals, sleeve orthosis improved elbow proprioception at 70°, whereas both counterforce and sleeve orthoses were effective at 110°.

肘部矫形器对无症状者肘部本体感觉的直接影响：随机假对照单盲研究。

背景：目的：本研究旨在评估肘部矫形器对无症状人群肘部本体感觉的直接影响：研究设计：这是一项随机、对照、单盲研究，采用假应用：60 名参与者被平均分配到三个矫形器组（反作用力组、套筒组和假体组）。在三个时间点：基线（BS）、佩戴矫形器后立即（IA）和佩戴矫形器 30 分钟后（30MA），使用主动关节位置感误差（JPSE）评估肘关节屈曲 70°和 110°时的运动感觉：组间差异70° 时，JPSE 无明显差异（p = 0.095）；但 110° 时，JPSE 有明显差异（p = 0.005）。不同时间点之间：在 70°时，JPSE 没有表现出显著差异（p = 0.055），而在 110°时则有显著差异（p = 0.020）。时间点×组别的交互作用：在 70°（p = 0.476）或 110°（p = 0.346）时均未观察到明显的交互作用。70° 时，在套筒组中，BS-30MA（p = 0.001）和 IA-30MA （p = 0.009）之间存在显著差异。110° 时，在套筒组中，BS-30MA（p = 0.007）和 IA-30MA（p = 0.007）之间存在显著差异。在反作用力组，BS-30MA 时间点之间存在显著差异（p = 0.001）。在 70° 时，反作用力组的总体评估结果没有发现差异（p > 0.05），而在 110° 时，则发现了显著差异（p = 0.026）。在70°和110°时，套筒组和假体组的整体评估结果均无差异（p > 0.05）：结论：对于无症状者，套筒矫形器可改善 70° 时的肘关节本体感觉，而在 110° 时，反作用力矫形器和套筒矫形器均有效。
