The recovery of shoulder muscle strength after open acromioplasty was evaluated in 48 patients (27 male, 21 female, mean age 44.3 years) who had undergone open acromioplasty because of stage II impingement syndrome. The isometric strengths of flexion, abduction and external rotation were measured before the operation and at 3, 6 and 12 months postoperatively. The mean preoperative flexion strength of the involved shoulder was 72.6% of that of the uninvolved shoulder, and this increased to 77.1% by 3 months post operation, to 88.3% at 6 and to 88.3% at 12 months. Corresponding abduction strengths were 68.4%, 80.4%, 88.7% and 91.0% and the external rotation strengths were 75.1%, 77.4%, 95.1% and 93.5%, respectively. These recoveries were markedly improved when the cases with poor subjective results at 1 year were not considered. The low preoperative strengths were more pronounced in women than in men, but recovery was better in women. It is concluded that shoulder muscle strengths recover to near normal in 1 year after open acromioplasty.
对48例因Ⅱ期撞击综合征接受开放性肩峰成形术的患者（27例男性，21例女性，平均年龄44.3岁）进行了开放性肩峰成形术后肩部肌肉力量恢复情况的评估。在手术前以及术后3个月、6个月和12个月测量了屈曲、外展和外旋的等长肌力。患侧肩部术前屈曲力量的平均值为健侧的72.6%，术后3个月增至77.1%，6个月时为88.3%，12个月时为88.3%。相应的外展力量分别为68.4%、80.4%、88.7%和91.0%，外旋力量分别为75.1%、77.4%、95.1%和93.5%。若不考虑1年时主观效果较差的病例，这些恢复情况有显著改善。术前力量较低在女性中比在男性中更明显，但女性的恢复情况更好。得出的结论是，开放性肩峰成形术后1年内肩部肌肉力量恢复至接近正常水平。
