The Effect of Motor Learning Exercises on Lateral Epicondylitis

In addition to the conventional physiotherapy program .... per week for 4 weeks Sessions of motor learning exercise will be performed. For the exercise, the participant will sit in a chair with back support, in front of a table, with arms on the table. The participant will wear a glove with an IMU sensor on the upper surface and a pressure sensor on the palm, and a cylinder will be placed in the palm. The participant will be asked to bring the wrist into extension and then back into flexion while grasping the cylinder with maximum force. The participant will be asked to maintain maximum strength during the entire movement. The participant will be given visual feedback on muscle strength and range of motion of the wrist on the monitor in front of them throughout the movement. The same protocol will be applied by keeping the size of the cylinder in the participant's palm the same and changing the weight.

The control group will receive a conventional physiotherapy program for 4 weeks, 5 days a week. Eccentric training for the extensor carpi radialis brevis (ECRB) muscle, the most affected wrist extensor tendon, and static stretching exercises for the ECRB muscle will be given. For eccentric training, the weight that the patients can lift in 10 maximal repetitions will be calculated and they will be asked to work with this weight. The best stretching position for the ECRB tendon is extension of the elbow joint, pronation of the forearm and flexion of the wrist with ulnar deviation. Each participant will be taught to perform each exercise for 10 repetitions and 10 seconds. Patients will perform these exercises in a sitting position. In the control group, daily exercises will be performed under the supervision of a physiotherapist
