Number of participants in this group is anticipated to be 20. Conventional physiotherapy and rehabilitation methods will be applied to this group. The conventional program includes the application of Transcutaneous Electrical Nerve Stimulation (TENS), cold pack, therapeutic ultrasound, Codman Exercises, Wand exercises, shoulder wheel exercises, finger ladder exercises, strengthening exercises with elastic band and capsule stretching.

Number of participants in this group is anticipated to be 20. Participants in this group will be receiving conventional physiotherapy and rehabilitation methods and 10 minutes of exercise with the game-based virtual reality system (USE-IT). In the USE-IT system two games will be played for 5 minutes each.

A game-based virtual reality device named USE-IT will be added to the rehabilitation program. USE-IT is a technological rehabilitation system designed by the Department of Physiotherapy and Rehabilitation at Hacettepe University. It is a smart gaming device which has been used in patients who suffer from movement loss in their upper extremities due to various neurological and orthopedic reasons.

The range of motion of the joints in the upper extremities will be measured using the universal goniometer before and after the treatment.

Level of Pain will be assessed with Visual Analogue Scale (VAS). It is widely used among the methods of measuring the severity of pain. Scale is a 10 cm ruler, participants will mark the level of pain between 0-10 cm, 0 would means ''no pain'' and 10 would means ''worst possible pain''.

Disability of the upper extremities will be assessed with 'The Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire'. It is a self-administered region-specific outcome instrument developed as a measure of self-rated upper-extremity disability and symptoms. The questionnaire was designed to help describe the disability experienced by people with upper-limb disorders and also to monitor changes in symptoms and function over time.

Quality of function of the shoulder will be assessed with Constant-Murley Score. It is a 100-points scale composed of a number of individual parameters. These parameters define the level of pain and the ability to carry out the normal daily activities of the patient. Pain (15 points), daily living activities (20 points), active range of motion (40 points) and force (25 points) parameters, including a total of 100 points system. The total Constant score is classified as excellent (30 <), good (21 - 30), medium (11 - 20) and weak (<11).

The muscle strength of shoulder flexion, abduction, adduction, external and internal rotation movements will be evaluated by using the Baseline Push-Pull (New York) dynamometer. Results will be calculated in kg (1 lb = 0.454 kg). The patient's arm will be stabilized and the patient will be asked to show maximum resistance within 2 sec against the dynamometer placed and then hold it for 5 seconds at this position and power. The measurement will be repeated twice and recorded with the average of these two values.
