Therapeutic Approaches for Subjects With Scapula Dyskinesis

National Taiwan University

Status: Completed

Conditions: Shoulder Impingement

Treatments: Other: Conscious control+biofeedback; Other: Conscious control

Study type: Interventional

Funder types: Other

Identifiers

NCT03252444

Details and patient eligibility

About

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.

Enrollment: 139 patients

Sex: All

Ages: 18 to 50 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• At least three positive of five tests, including Neer's test, Hawkin's test, Empty can test, tenderness in tendon of rotator cuff and resisted external test.
• Each patient will need a prescription of the physician or orthopedic surgeon for diagnosing impingement symptoms

Exclusion criteria

• Shoulder pain onset due to trauma, a history of shoulder fractures or dislocation, cervical radiculopathy, degenerative joint disease of the shoulder, surgical interventions on the shoulder, or inflammatory arthropathy

139 participants in 2 patient groups

Biofeedback group

Experimental group

Description:

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.

Treatment:

Other: Conscious control+biofeedback

Conscious control group

Active Comparator group

Description:

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

Treatment:

Other: Conscious control
