Lateral epicondylitis (LE), also called tennis elbow, is a common musculoskeletal disorder that causes pain in the elbow area and is highly prevalent in assembly workers who repeatedly move their wrists.
The purpose of this study was to compare the wrist ROM and muscle strength of assembly workers with and without LE.
Forty-five male assembly line workers (23 with LE) participated in the study. Participants had their wrist range of motion (flexion, extension, ulnar deviation, and radial deviation) and strength (wrist flexors, extensors, and hand grip) measured using Smart KEMA sensors.
Workers with LE showed significantly reduced wrist extension and radial deviation ROM compared to workers without LE, with no significant differences in wrist flexion and ulnar deviation ROM between groups. Workers with LE had significantly lower wrist extensor strength compared to workers without LE, and there was no significant difference in wrist flexor and grip strength between the two groups.
For workers with LE, the difference in wrist ROM and muscle strength will be useful for planning intervention and evaluating treatment outcomes for assembly workers with LE.
外侧上髁炎（LE），又称网球肘，是一种常见的肌肉骨骼疾病，会导致肘部区域疼痛，在反复活动手腕的装配工人中极为普遍。
本研究旨在比较患有和未患有外侧上髁炎的装配工人的腕关节活动度和肌肉力量。
45名男性装配线工人（23名患有外侧上髁炎）参与了本研究。使用Smart KEMA传感器测量参与者的腕关节活动范围（屈曲、伸展、尺侧偏斜和桡侧偏斜）和力量（腕屈肌、伸肌和握力）。
与未患外侧上髁炎的工人相比，患外侧上髁炎的工人腕关节伸展和桡侧偏斜活动度显著降低，两组之间腕关节屈曲和尺侧偏斜活动度无显著差异。与未患外侧上髁炎的工人相比，患外侧上髁炎的工人腕伸肌力量显著降低，两组之间腕屈肌和握力无显著差异。
对于患有外侧上髁炎的工人，腕关节活动度和肌肉力量的差异将有助于为患有外侧上髁炎的装配工人制定干预计划和评估治疗效果。
