【摘要】：目的:探討分析運(yùn)動(dòng)性肩袖損傷后肩袖肌群表面肌電和等速肌力測試特征的變化。方法:選取肩袖損傷的運(yùn)動(dòng)員30例,其中男18例,女12例,平均年齡為21.2±2.2歲。同時(shí)選取同一院系年齡、性別構(gòu)成比相近的健康運(yùn)動(dòng)員30例作為對(duì)照組,其中男16例,女14例,平均年齡為21.5±2.0歲。兩組患者均同時(shí)進(jìn)行表面肌電和等速肌力測試。結(jié)果:肩袖損傷組運(yùn)動(dòng)員肩關(guān)節(jié)在角速度為60°/s,90°/s外展時(shí)岡上肌、岡下肌積分肌電值(i EMG)值比對(duì)照組低,差異有統(tǒng)計(jì)學(xué)意義(P0.05),尤其是岡下肌差異更顯著(P0.01)。肩袖損傷組運(yùn)動(dòng)員肩關(guān)節(jié)在角速度為120°/s外展時(shí)岡上肌、岡下肌i EMG值比對(duì)照組低,差異有統(tǒng)計(jì)學(xué)意義(P0.01)。肩袖損傷組運(yùn)動(dòng)員肩關(guān)節(jié)在角速度為60°/s外旋時(shí)所有肌肉i EMG值與對(duì)照組比較,差異無統(tǒng)計(jì)學(xué)意義(P0.05);肩袖損傷組運(yùn)動(dòng)員肩關(guān)節(jié)在角速度為90°/s、120°/s外旋時(shí)岡下肌i EMG值比對(duì)照組低,差異有統(tǒng)計(jì)學(xué)意義(P0.05)。與對(duì)照組比較,肩袖損傷組運(yùn)動(dòng)員肩關(guān)節(jié)在角速度為60°/s,90°/s,120°/s外旋時(shí)所有肌肉i EMG值均無明顯改變(P0.05)。肩袖損傷組運(yùn)動(dòng)員肩關(guān)節(jié)在角速度為60°/s,90°/s,120°/s時(shí)的外旋/內(nèi)旋,外展/內(nèi)收峰力矩值比對(duì)照組低,差異有統(tǒng)計(jì)學(xué)意義(P0.05或P0.01)。結(jié)論:肩袖損傷運(yùn)動(dòng)員在外展時(shí)岡上肌、岡下肌肌肉募集較差,而三角肌、小圓肌無異常;同時(shí),肩袖損傷后三角肌中束和岡上肌合力作用下降而致肩關(guān)節(jié)外展能力減弱。
[Abstract]:Objective: to investigate the changes of surface electromyography and isokinetic muscle strength of rotator cuff group after rotator cuff injury. Methods: 30 athletes with rotator cuff injury were selected, including 18 males and 12 females. The average age was 21.2 鹵2.2 years. 30 healthy athletes with the same school age and similar sex ratio were selected as the control group, including 16 males and 14 females. The mean age was 21. 5 鹵2. 0 years. The mean age was 21. 5 鹵2. 0 years. Surface electromyography and isokinetic muscle strength tests were performed in both groups. Results: the shoulder joint of the rotator cuff injury group was 60 擄/ s at angular velocity. At 90 擄/ s abduction, the integral EMG (I EMG) of supraspinatus and infraspinatus was lower than that of the control group (P 0.05). In the rotator cuff injury group, I EMG of the supraspinatus muscle and the infraspinar muscle were lower than that of the control group at the angle velocity of 120 擄/ s. The difference was statistically significant (P 0.01). The I EMG values of all muscles in the rotator cuff injury group were compared with those in the control group when the angular velocity was 60 擄/ s. The difference was not statistically significant (P 0.05). In the rotator cuff injury group, I EMG was lower in the shoulder joint at the angle velocity of 90 擄/ s or 120 擄/ s than that in the control group, and the difference was statistically significant (P 0.05). The shoulder joint of the rotator cuff injury group was 90 擄/ s at the angular velocity of 60 擄/ s. There was no significant change in the I EMG value of all muscles during 120 擄/ s external rotation. The shoulder joint of the rotator cuff injury group was at an angular velocity of 60 擄/ s ~ 90 擄/ s. The external rotation / internal rotation and abduction / adductive peak torque of 120 擄/ s were lower than that of the control group (P 0.05 or P 0.01). Conclusion: the rotator cuff injury athletes' supraspinatus muscle. The muscle recruitment of the infraspinar muscle was poor, but the deltoid muscle and the lesser round muscle were not abnormal. At the same time, the joint action of deltoid muscle and supraspinatus muscle decreased after rotator cuff injury.

【正文快照】： 運(yùn)動(dòng)性肩袖損傷是常見的肩部運(yùn)動(dòng)損傷之一。主要表現(xiàn)為肩關(guān)節(jié)疼痛及活動(dòng)受限[1]。多見于上肢過頂類(overhead)運(yùn)動(dòng)項(xiàng)目如網(wǎng)球、棒球、排球、游泳等,多因過度使用導(dǎo)致疲勞性損傷。出現(xiàn)運(yùn)動(dòng)性肩袖損傷后肩袖肌群的功能包括肌肉力量及耐力等均出現(xiàn)不同程度的下降,導(dǎo)致肩關(guān)節(jié)的疼
