Individuals who will participate in the study will be treated 2 days a week for 5 weeks with Leap Motion sensor-supported games aimed at increasing patient-specific wrist flexion, wrist extension, ulnar and radial deviation of the wrist, flexion, extension and abduction of the fingers. Each training period will last 30 minutes.

They will be included in traditional rehabilitation training consisting of stretching exercises, strengthening exercises and functional exercises including activities of daily living for 2 days a week for 5 weeks.

Hand Therapy via leap motion sensor

Hand Mobility in Scleroderma is a hand function test developed for adults who have systemic sclerosis. HAMIS consists of 9 items designed to measure all movements assessed in an ordinary range of motion-measured hand test. Each item is graded on a 0-3 scale, where 0 corresponds to normal function and 3 denotes that the individual is unable to perform the item. Each hand is assessed separately. The total score of HAMIS for each hand is 370 Sandqvist and Eklund Vol. 13, No. 6, December 2000 27, which represents a high degree of dysfunction.

The patients will be asked to close their fingers tightly and the distance between the pulp of the 2nd, 3rd, 4th, and 5th finger - distal palmar line (PP-DPD) will be measured in cm with the help of a ruler. Dominant and nondominant hand total scores will be calculated by summing the values found for the fingers of each hand separately.
