Focal Vibration Group Training with Focal Vibration on the deltoid, trapezius, and biceps muscles with an amplitude of 1.2 mm. Time of training 20-25 min. The configuration of the vibration program will be in an automatic mode of 10 seconds of vibration and 3 seconds of rest to avoid the coupling of the mechanoreceptors. Patients will be treated with FV for three consecutive days: each session consisted of three sessions of 10 minutes each, interspersed with one minute of rest. A vibration frequency of 40 Hz to 100 Hz has been applied, according to the literature. The group also received the Traditional Training.

Traditional Training Warm up, grade 1 and 2 mobilization and stretching exercises, strength training, range of motion exercises, and coordination training.

The home exercises program is programmed.

Myovolt delivers oscillatory mechanical vibration of focussed frequency and low amplitude to stimulate physiological benefits in soft tissues. Myovolt is non-aggressive and gentle to the body so can be safely targeted. Digitally tuned to transmit a discrete vibration frequency range between 30 - 100Hz for effective neuromuscular stimulation.

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.

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

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.
