Efficacy of dynamic humeral centering according to Neer test results
本研究分析了动态肱骨中心化技术对肩峰撞击综合征患者的疗效，发现该技术对Neer试验阳性患者效果更好。
The aim of this study was to assess the efficacy of dynamic humeral centering (DHC) according to Neer test results. The study was a stratified analysis of a previously reported randomized trial. The patients included had shoulder pain with impingement syndrome. Interventions were DHC or nonspecific mobilization for control. The primary outcome was the Constant score including subscores for pain, activity, mobility, and strength at 3 months. All patients improved at follow-up, with better results after DHC. There was no interaction between Neer test results, treatments, and time. However, a trend toward higher effect sizes was observed after DHC in patients with a positive Neer test in comparison with negative patients. Patients with a positive Neer test showed improvement after DHC for rotator cuff disease compared with nonspecific mobilization.
