Effectiveness of Focal Vibration in Shoulder Pathology

Change from Baseline Shoulder Pain at 4 weeks

Evaluation of shoulder pain was performed using the Visual Analog Scale. The score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" on the far left and "the most intense pain imaginable" on the far right.The patient places a mark at a point on the line corresponding to the patient's rating of pain intensity. A higher score indicates greater pain intensity.

Change from 4 weeks Shoulder Pain at 6 weeks

Change from Baseline Range of Motion of Shoulder Joint at 4 weeks

The joint movements of the affected shoulder was measured using a digital electrogoniometer. A higher score indicates greater improvement.

Change from 4 weeks Range of Motion of Shoulder Joint at 6 weeks

The joint movements of the affected shoulder was measured using a digital electrogoniometer. A higher score indicates greater improvement.

Change from Baseline Shoulder Function at 4 weeks

Function was assessed using the self-administered Shoulder Pain and Disability Index.The Shoulder Pain and Disability Index contains 13 items that assess two domains; a 5-item subscale that measures pain and an 8-item subscale that measures disability. Each subscale is summed and transformed to a score out of 100. A mean is taken of the two subscales to give a total score out of 100, higher score indicating greater impairment or disability.

Change from baseline Shoulder Muscle Tone at 6 weeks

The muscle tone which is a biomechanical property of the shoulder muscles will be evaluated with a portable hand-held myotonometer. This myotonometer (MyotonPRO - Tallinn, Estonia) is non-invasive and provides a quantitative assessment of a muscle's biomechanical properties. The MyotonPRO applies a short-intensity mechanical impulse on the skin overlying the muscle. The tissue's response then generates a signal that is recorded, and an internal software program produces an acceleration graph.
