Abstract：
BACKGROUND: Shoulder girdle pain is a common disabling complaint with a high lifetime prevalence. Interventions aimed at decreasing shoulder pain without stressing shoulder girdle structures have the potential to improve participation in multimodal shoulder rehabilitation programs.
OBJECTIVE: The aim of this study was to determine the acute effects of moderate intensity lower extremity exercise on mechanically induced shoulder pain in individuals without shoulder injury. It was hypothesized that participants would exhibit less shoulder pain, as indicated by increased pain thresholds, following lower extremity exercise.
METHODS: Repeated measures study.
METHODS: Thirty (30) healthy participants were recruited to participate in this study. Pain pressure algometry was used to mechanically induce shoulder pain over the infraspinatus muscle belly. This was performed on the dominant shoulder before and immediately after performing 10 minutes of moderate intensity lower extremity exercise using a recumbent exercise machine. Heart rate and rate of perceived exertion were measured following exercise. Repeated measures ANOVA was used to compare pain pressure threshold scores between the baseline and post-exercise time points. Significance was set at p ≤ 0.05 a priori. Effect size (ES) was calculated using Glass\'s Δ.
RESULTS: Moderate intensity lower extremity aerobic exercise led to significantly (F = 8.471, p = 0.003) decreased evoked shoulder pain in healthy adults with moderate effect sizes (0.30-0.43).
CONCLUSIONS: Lower extremity aerobic exercise significantly decreased pain of the infraspinatus in this sample of young healthy participants. Utilization of lower extremity exercise may be of benefit for younger patients to decreased acute shoulder pain.
METHODS: 2b: individual cohort study.

摘要：
背景：肩带疼痛是一种常见的致残主诉，终生患病率高。旨在减轻肩痛而不对肩带结构造成压力的干预措施有可能改善对多模式肩关节康复计划的参与。
目的：本研究的目的是确定中等强度下肢运动对无肩关节损伤者机械性肩痛的急性影响。假设参与者会表现出更少的肩部疼痛，如疼痛阈值增加所示，下肢运动后。
方法：重复测量研究。
方法：招募30名健康参与者参与本研究。疼痛压力测量用于机械地诱发冈下肌腹部的肩部疼痛。这是在使用横卧锻炼机进行10分钟中等强度下肢锻炼之前和之后立即在优势肩部上进行的。运动后测量心率和感知的劳累率。重复测量ANOVA用于比较基线和运动后时间点之间的疼痛压力阈值评分。显著性先验地设定为p≤0.05。使用GlassΔ计算效应大小(ES)。
结果：中等强度的下肢有氧运动可显著(F=8.471,p=0.003)减少中等效应大小的健康成人诱发的肩痛(0.30-0.43)。
结论：在这个年轻的健康参与者样本中，下肢有氧运动显著降低了冈下肌的疼痛。下肢运动的利用可能有利于年轻患者减少急性肩痛。
方法：2b：个体队列研究。
