Indirect evaluation tests of somatosensory integrity, such as the left/right judgment task and two-point discrimination thresholds, are used to complement a clinical evaluation facilitating tailored rehabilitation programs for patients with chronic pain. This study aimed to compare performance on the left/right judgment task and two-point shoulder discrimination thresholds between people with chronic shoulder pain and asymptomatic controls. The study's secondary objective was to investigate whether there is a relationship between pain intensity and the painful area with TPDT and LRJT.
It is a cross-sectional study with a control group. Volunteers participated in the left/right judgment task using the Recognise Shoulder app, and two-point discrimination thresholds were performed using a Mitutoyo® digital caliper. The extent of the painful area, affectivity, and functionality were also determined to characterize the sample.
We assessed 52 symptomatic and 50 asymptomatic individuals. A between-group difference was observed in time response for the left/right judgment task (p = 0.025) and the two-point discrimination thresholds when tested over the shoulder's lateral region (p = 0.012). There was a significant positive weak correlation between pain intensity and TPDT test performance over the anterior shoulder (rs = 0.35; p = 0.01) and a positive weak correlation between pain area and LRJT response time (rs = 0.26; p = 0.04).
This study demonstrates a difference of small magnitude in the response time of the LRJT for the shoulder segment and TPDT in the lateral shoulder region between individuals with chronic shoulder pain and asymptomatic controls.
躯体感觉完整性的间接评估测试，如左右判断任务和两点辨别阈值，用于补充临床评估，为慢性疼痛患者制定个性化的康复计划。本研究旨在比较慢性肩痛患者和无症状对照者在左右判断任务和肩部两点辨别阈值上的表现。本研究的次要目的是探讨疼痛强度和疼痛区域与 TPDT 和 LRJT 之间是否存在关系。
这是一项横断面研究，设有对照组。志愿者使用 Recognise Shoulder 应用程序参与左右判断任务，使用 Mitutoyo®数字卡尺进行两点辨别阈值测试。还确定了疼痛区域的范围、情感和功能，以对样本进行特征描述。
我们评估了 52 名有症状者和 50 名无症状者。在左右判断任务的时间反应（p=0.025）和肩部外侧区域的两点辨别阈值测试中观察到组间差异（p=0.012）。疼痛强度与前肩部 TPDT 测试表现之间存在显著的正弱相关（rs=0.35；p=0.01），疼痛区域与 LRJT 反应时间之间存在正弱相关（rs=0.26；p=0.04）。
本研究表明，慢性肩痛患者和无症状对照者在肩部左右判断任务的反应时间和肩部外侧两点辨别阈值测试方面存在小幅度差异。
