Electrotherapy program in our study 20 minutes, Hot-pack (HP) 20 minutes, 60-120 Hz frequency range 50-100 millisecond pulse time conventional TENS (Transcutaneous Electrical Nerve Stimulation) and 5 minutes 1.5 watt / cm2 treatment dosage 1 MHz ' ultrasound (US) treatment was applied. Exercise program; Eccentric and concentric strengthening and stretching of ECBR and ECBL muscles, terminal elbow flexion and extension, forearm pronation and supination exercises were given. Electrotherapy was given as 15 sessions for 6 weeks, 2 or 3 days a week, 1 session per day, and 30 sessions for 6 weeks, 5 days per week. Fifteen of these exercise sessions were supervised by the physiotherapist in the hospital and the remaining 15 patients did not come to the clinic on their own. The experimantel group was given strengthening exercises of the upper trapezoidal, middle trapezoidal and serratus anterior muscles with extra scapula muscles.

Control Group

In order to evaluate the general pain severity of the patients, Visual Analog Scale (VAS), which is the Visual Pain Scale of Turkish, was used. Patients were asked to mark their general pain separately on a 10 cm scale. According to this, "0" indicates that there is no pain, and "10" indicates the most severe pain. The distance between the marked point and the beginning of the line was recorded in centimeters

In order to record the EMG signals of the ECRB muscle, the bipolar Ag / AgCl was adhered to the designated area at a distance of 1 cm between the centers of the superficial electrodes according to SENİAM criteria and the reference electrode was placed in the farthest region. Before the electrodes were bonded, the skin surface was shaved with a razor blade and cleaned with isopropyl alcohol to get a better signal. The measurements were made simultaneously in grip position with the automatically tuned EMG biofeedback.

In order to determine the level of functional, "Arm, Shoulder and Hand Problems Questionnaire (DASH-T)" was used. The scale consists of three parts. The first 21 questions assess the patient's difficulty during daily life activities, 5 questions assess symptoms (pain, pain due to activity, tingling, stiffness, weakness), and the remaining 4 questions assess social function, work, sleep and self-confidence. Each question is scored from 1 to 5 and subtracted from 1, multiplied by 25. A high score indicates a bad apology.

In order to measure yhe functionality Upper Extremity Functionality Indeks (UEFI) was used. It consists of 8 questions. These include questions such as opening jars, driving more than 30 minutes, sleeping, writing, grasping small objects with their fingers, taking jugs from the refrigerator, opening doors and washing dishes. A visual scale is asked for each question. 1 shows that there is no pain and 10 indicates that the pain is the most severe. The total score is between 8-80.

Grip force was made by JAMAR brand dynamometer. The first measurement was performed with the elbow 90o flexed in the sitting position, the forearm in the neutral position, the shoulder adduction, the wrist between 0-30o and arm supported in the chair, the second measurement was repeated averaged five times while the arm was in adduction in the elbow extension, and the mean was recorded in terms of (lbs) -force.
