简要总结
The investigators will test whether conscious control with manual guides and video or EMG biofeedback will enhance 3-D kinematics of scapula in shoulder dysfunction subjects with different type of scapula dyskinesis. The investigators will also examine how correction of scapular orientation may affect the activation of associated muscles during various dynamic movements in these subjects.

研究组 & 干预措施
Biofeedback group
After 1 minute of rest, participants will perform 6 trials of bilateral, active, weighted arm elevation in the scapular plane and a therapist classifies the scapular motion into specific patterns of scapular dyskinesis. After the evaluation of scapular dyskinesis, the kinematics and surface EMG (sEMG) data will be collected during 5 trials of the same arm movements and 3 selected exercises.
干预措施: Conscious control+biofeedback (Other)
Conscious control group
Conscious correction of scapular orientation will be taught to the subjects in the manner described in previous studies. The starting position is determined in each individual by actively positioning the scapula between maximal upward and downward rotation, external and internal rotation, and posterior and anterior tilt. Scapular assistance test (SAT) is also conducted by passively assisting patients' scapula into appropriate position to correct scapula dyskinesis
干预措施: Conscious control (Other)
结局指标
主要结局
Shoulder complex kinematics
时间窗: The scapular kinematics will be measured before scapular control and immediately after scapular control
Scapular orientation relative to the thorax is described using a Euler angle sequence of rotation about Zs (protraction/retraction), rotation about Y's (downward /upward rotation), and rotation about X"s (posterior/anterior tipping). Scapular elevation is defined as the vertical displacement of the scapular sensor during arm elevation. Humeral orientation relative to the scapula is described using a Euler angle sequence in which the first rotation represents the plane of elevation, the second rotation defines the amount of elevation, and the third rotation describes the amount of axial rotation.
Shoulder associated muscular activities
时间窗: The muscle activation will be measured before scapular control and immediately after scapular control
Full bandwidth sEMG data, captured by data acquisition software (AcqKnowledge, Biopac systems Inc., CA, USA)
次要结局
- Pectoralis minor muscle length(After subjects are included in the study, the muscle length will be measured before scapular control, and be done within 2 hours.)
- Forward shoulder posture(After subjects are included in the study, the forward shoulder posture will be measured before scapular control, and be done within 2 hours.)
