Muscular strength imbalance (MSI) on shoulder and neck is often a detonate for shoulder and neck postural diseases, for this reason, improving the neck/shoulder muscle imbalance could be a good method to prevent neck and shoulder problems. PURPOSE: This study tested the efficacy of Baduanjin exercise (BDJ), a traditional Chinese mind-body exercise, on shoulder and neck muscle strength imbalance, and see if it is possible through this method provide a new idea of sports rehabilitation for shoulder and neck diseases problems. METHODS:40 sedentary university students, with either forward head posture and/or round shoulder posture were randomized to the BDJ intervention group (n=20) and control group (n=20), the same evaluation protocol was used before and after the intervention. During six weeks of training, The BDJ group was given Baduanjin training combined with a basic health education program, and the control group was treated only with a basic health education program. Baduanjin training was conducted three times a week, every time 50 minutes. The contents of health education program include healthy lifestyle tips, postural education and muscle stretching method. RESULTS: Significant changes were found within the BDJ group, specially on Forward Head Angle test, Maximal Internal/External Rotation test and upper quarter Y-balance test. CONCLUSIONS: this randomized control trial provides some evidence to support the positive effect of BDJ exercise as a new method of sport therapy for rehabilitation among people with shoulder/neck MSI.
