Clinical Trial Summary

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.

Eligibility

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

Related Conditions & MeSH terms

• Dyskinesias
• Shoulder Impingement

Intervention

Other:
• Conscious control
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
• Conscious control+biofeedback
In electromyography (EMG) biofeedback training, electronic equipment is used to reveal instantaneously certain physiological events.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Shoulder complex kinematics	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.	The scapular kinematics will be measured before scapular control and immediately after scapular control
Primary	Shoulder associated muscular activities	Full bandwidth sEMG data, captured by data acquisition software (AcqKnowledge, Biopac systems Inc., CA, USA)	The muscle activation will be measured before scapular control and immediately after scapular control
Secondary	Forward shoulder posture	The measurement of the distance between the posterior border of the acromion and the table	After subjects are included in the study, the forward shoulder posture will be measured before scapular control, and be done within 2 hours.
Secondary	Pectoralis minor muscle length	The distance from the fourth rib to the coracoids process will be measured with FASTRAK system with accuracy of 0.08 cm. This distance (in centimeter) is divided by the subjects height and multiplied by 100. This results in a pectoralis muscle length index	After subjects are included in the study, the muscle length will be measured before scapular control, and be done within 2 hours.
