Participants in this group are going to be in physiotherapy program, which is created specific to diabetic patients, contains;

• Exercises for stability, flexibility and strength,
• Exercises which improves wrist proprioception,
• Exercises for sensation recovery,
• Mirror therapy and motor imagination
• Physiotherapy program will be changed in every 3 weeks. Participant will be informed about their disease, about process of healing and will check by phone calls 2 times a week. They will be given recommendations about disease management. Home exercises will be given to this group and will be added new exercises every 3 weeks while physiotherapy program continues.

Control group will take conventional physiotherapy as in the literature. Diabetic individuals in routine takes aerobic exercise recommendation and resistive exercises. In our study control group will continue 12 sessions of resistive exercise program focused on upper extremity, also aerobic exercise recommendation.

• Joints targeted by exercise; bilateral wrist, metacarpophalangeal, proximal and distal interphalangeal joints, elbow and shoulder joints.
• The muscles targeted by the exercises; lumbricals, iinterosseals, thenar and hypothenar muscles, forearm flexors, forearm extensors, forearm supinators and pronators, elbow flexors and extensors, and shoulder girdle muscles.
• Content of the exercises; There will be warm-up exercises, pinch grip, full grip, nerve and tendon gliding exercises, exercises that improve proprioception, functional exercises, strengthening exercises and stretching exercises.

35 degrees wrist flexion and 45 degrees wrist extension will be taught to the patient, and the patient will be asked to bring the wrist to the same position with eyes closed, and the angle of deviation will be measured with a goniometer and recorded.

The 9-Hole Peg Test, which is a valid and reliable assessment method, will be used to evaluate the hand and finger dexterity of the patients. Randomly placing 9 wooden pins on the 9-hole wooden block as quickly as possible and then removing the pins one by one from the wooden block and placing them in the storage section will be recorded by measuring with a stopwatch. By calculating the total time, 20 seconds or more will be considered as a loss of skill.

The Quick Diasbilities of Arm, Shoulder and Hand (DASH) questionnaire will be used to determine the level and symptoms of physical disability in the upper extremity. Higher scores indicate higher disability in the upper extremity. The Michigan Hand Outcome Questionnaire is used to evaluate complaints in the hands of patients. It can evaluate each hand separately and was developed to evaluate the symptoms of all hand disorders. The parameters it evaluates respectively; function, daily activities, work performance, pain, aesthetics, satisfaction. A high score in the pain domain indicates worsening, and a high score in all other domains indicates a better condition. The total score is obtained by summing the results of the affected extremity or, if bilateral extremities are affected, by adding the mean scores of the areas and dividing by six. This questionnaire is valid and reliable for Turkish society.

Grip strength will be evaluated using the Jamar Dynamometer. The average of three attempts for each hand will be recorded in kilograms. This test is a reliable and valid test to evaluate manual grip strength.
