Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Conscious control+biofeedback

Intervention Type OTHER

In electromyography (EMG) biofeedback training, electronic equipment is used to reveal instantaneously certain physiological events.

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

Group Type ACTIVE_COMPARATOR

Conscious control

Intervention Type OTHER

Conscious control of the scapula is important and can correct neuromuscular coordination as well as strength deficits. The strategy in learning control of scapula into normal orientation can be facilitated by manual guides and/or external cues
