Objective: Determine the prevalence of lateral epicondylosis (LE) of the dominant elbow in manual wheelchair users based on ultrasound assessment and physical exam.

Design: Prospective, cross-sectional.

Setting: National Veteran Wheelchair Games 2018 and 2019 (event medical services).

Participants: Manual wheelchair users who attended the National Veteran Wheelchair Games (n = 87).

Interventions: Participants completed a questionnaire then underwent an ultrasound assessment and a physical exam of their dominant arm evaluating for common extensor tendinopathy (CET) or clinically LE.

Main Outcome Measure: Prevalence of CET diagnosed by ultrasound criteria was compared with other diagnostic criteria with MaNemar test for paired binary data.

Results: Forty-six percent (N = 40) of participants met diagnostic criteria for CET by ultrasound assessment and 17% (N = 15) of participants met criteria for LE based on physical exam. These values are dramatically higher than what has been reported in the able-bodied population where the prevalence is estimated to be <2%. Age and number of years of wheelchair use were significant predictors of ultrasound diagnosis of LE (P = 0.02, 95% confidence interval [CI] 1.01–1.11) and (P = 0.05, 95% CI 1.00–1.09), respectively. Association analysis based on odds ratio and CI found no association between ultrasound findings suggestive of LE with regular adaptive sport participation greater than 1.5 h per week.

Conclusion: Compared to able-bodied population, there is an increased prevalence of both CET and LE in manual wheelchair users based on either ultrasound assessment or physical exam. CET is associated with increased age and increased years using a manual wheelchair. There is no association between the diagnosis of LE and participation in adaptive sport.

目的：根据超声评估和体格检查，确定手动轮椅使用者主要肘部外上髁病 (LE) 的患病率。

设计：前瞻性，横截面。

设置： 2018 年和 2019 年全国退伍军人轮椅运动会（赛事医疗服务）。

参与者：参加过全国老兵轮椅运动会的手动轮椅使用者（n  = 87）。

干预措施：参与者完成了一份问卷，然后接受了超声评估和主要手臂的体格检查，以评估常见的伸肌腱病 (CET) 或临床上的 LE。

主要结果测量：通过配对二元数据的 MaNemar 检验将超声标准诊断的 CET 的患病率与其他诊断标准进行比较。

结果： 46% ( N  = 40) 的参与者通过超声评估符合 CET 的诊断标准，17% ( N  = 15) 的参与者符合基于体检的 LE 标准。这些值显着高于在健全人群中报告的患病率估计<2%。年龄和使用轮椅的年数分别是 LE 超声诊断的重要预测因子（P = 0.02, 95% CI 1.01-1.11）和（P = 0.05, 95% CI 1.00-1.09）。基于优势比和 CI 的关联分析发现，提示 LE 的超声结果与每周超过 1.5 小时的定期适应性运动参与之间没有关联。

结论：与身体健全的人群相比，根据超声评估或体格检查，手动轮椅使用者中 CET 和 LE 的患病率增加。CET 与使用手动轮椅的年龄增加和年数增加有关。LE 的诊断与参与适应性运动之间没有关联。
