The purpose of this case-control study was to examine potential agonist-antagonist fatigue imbalance during wheelchair rugby activity. A 16-channel NORAXON electromyography (EMG) system 1400A with telemetry was used to assess EMG activity in a 39-year-old male with a C6 complete spinal cord injury (American Spinal Injury Association Impairment Scale (AIS) A), 17.5 years post injury. Mean amplitude and median frequency were determined for push-phase agonists (anterior deltoid and pectoralis major) and antagonist (posterior deltoid) across four training sessions at a community fitness and Paralympic training facility. Unlike continuous wheelchair pushing, acute muscle imbalances between agonists and antagonists (that is, push and recovery muscles) were not demonstrated. Wheelchair sports such as rugby may reduce risk of shoulder pain and overuse injury due to intermittent activity rather than continuous pushing. The current study is one of the first to document sport fatigue through electromyography during intermittent, live play rather than clinical conditions (that is, continuous pushing).
这项病例对照研究的目的是检查轮椅橄榄球活动期间潜在的激动剂 - 拮抗剂疲劳失衡情况。使用带有遥测功能的16通道NORAXON肌电图（EMG）系统1400A来评估一名39岁男性的肌电图活动，该男性患有C6完全性脊髓损伤（美国脊髓损伤协会损伤量表（AIS）A级），受伤后17.5年。在社区健身和残奥会训练设施进行的四次训练课程中，测定了推阶段激动剂（三角肌前束和胸大肌）和拮抗剂（三角肌后束）的平均幅度和中位频率。与持续推动轮椅不同，未显示激动剂和拮抗剂（即推动和恢复肌肉）之间存在急性肌肉失衡。像橄榄球这样的轮椅运动可能会降低因间歇性活动而非持续推动导致的肩部疼痛和过度使用损伤的风险。本研究是首批通过肌电图记录间歇性现场比赛而非临床条件（即持续推动）下运动疲劳的研究之一。
