Flexor and extensor muscle-tendon unit activity at the elbow during the golf swing was recorded from subjects with and without medial epicondylitis. There was no significant difference in total swing time between symptomatic (1.23 +/- 0.15 sec) and asymptomatic (1.15 +/- 0.13 sec) subjects nor between golfers with low (1 to 6 handicap, N = 8) and high (11 to 19 handicap, N = 8) scoring abilities. Symptomatic and asymptomatic subjects displayed similar electromyographic profiles for flexor and extensor muscles of the forearm. Electromyographic activity of the common extensor muscles was persistent throughout the four swing phases, ranging from 33.59% of maximum voluntary contraction at address to 58.77% at contact. Common flexor muscles produced a consistent burst of electromyographic activity during contact phase (flexor burst, 90.77% of maximum voluntary contraction). Symptomatic subjects' mean flexor muscle electromyographic activity was significantly greater than that of asymptomatic subjects in both address and swing phases. When forearm brace and oversized grips were imposed on symptomatic subjects, there was no significant difference in mean electromyographic magnitude or muscle activation pattern during the golf swing. Thus, the method of symptomatic relief of the intervention strategies tested is still in question.
记录了患有和未患有内侧上髁炎的受试者在高尔夫挥杆过程中肘部屈肌和伸肌肌腱单位的活动情况。有症状的受试者（1.23±0.15秒）和无症状的受试者（1.15±0.13秒）之间，以及低得分能力的高尔夫球手（差点为1至6，N = 8）和高得分能力的高尔夫球手（差点为11至19，N = 8）之间，总挥杆时间均无显著差异。有症状和无症状的受试者在前臂屈肌和伸肌的肌电图表现相似。在整个四个挥杆阶段，伸肌总肌电图活动持续存在，从站位时最大自主收缩的33.59%到击球时的58.77%不等。屈肌总肌在击球阶段产生持续的肌电图活动爆发（屈肌爆发，最大自主收缩的90.77%）。有症状受试者在站位和挥杆阶段的屈肌平均肌电图活动显著高于无症状受试者。当给有症状的受试者使用前臂支撑带和加大号握把时，在高尔夫挥杆过程中，平均肌电图幅度或肌肉激活模式没有显著差异。因此，所测试的干预策略的症状缓解方法仍存在疑问。
