About this trial
This is an interventional treatment trial for Shoulder Impingement focused on measuring Shoulder dyskinesis, EMG biofeedback training, Intensive Scapula-focused intervention
Eligibility Criteria
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

Conscious control group
Arm 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.
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
Outcomes
Primary Outcome Measures
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.
Shoulder associated muscular activities
Full bandwidth sEMG data, captured by data acquisition software (AcqKnowledge, Biopac systems Inc., CA, USA)
Secondary Outcome Measures
Forward shoulder posture
The measurement of the distance between the posterior border of the acromion and the table
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

5. Study Description
Brief 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.

Intervention Type
Other
Intervention Name(s)
Conscious control
Intervention Description
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
Intervention Type
Other
Intervention Name(s)
Conscious control+biofeedback
Intervention Description
In electromyography (EMG) biofeedback training, electronic equipment is used to reveal instantaneously certain physiological events.
Primary Outcome Measure Information:

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.
Time Frame
The scapular kinematics will be measured before scapular control and immediately after scapular control
