Individuals in this group will be given hand exercises (wrist flexion, extension and deviations) for 45 minutes, 2 days a week for 8 weeks, using a leap motion control device and games selected in accordance with this device.

Hand exercises (wrist flexion, extension and deviations)) will be applied to individuals in this group under the supervision of a specialist physiotherapist for 45 minutes, 2 days a week for 8 weeks.

This group is waiting list. After the study, patients will do hand exercises with the leap motion controller device.

Conventional hand therapy

Hand grip strength will be measured with a Jamar hydraulic hand dynamometer. Grip tests will be performed in the standard position recommended by the American Association of Hand Therapists. This is the standard position; The patient will be seated in a position that provides 90-20 degree flexion of the hip and knee, shoulder adduction, forearm neutral position, 90 degree flexion of the elbow, 0-30 degree extension of the wrist and 0-15 degree ulnar deviation. The measurement will be repeated three times. There will be a 15-second rest break at the end of each measurement. As a result, the average of three measurements will be recorded.

This test consists of tasks involving grasping types commonly used in daily living activities and evaluates people's speed in these tasks. Each stage of the Jebsen Taylor Hand Function Test, which consists of seven sub-steps, will be explained to the individuals in detail before the task and the individuals will be asked to try the task. Estimated time to complete 7 subtasks is 20 minutes. Individuals will complete tasks with both their dominant and non-dominant hands. The task will start with the practitioner's "start" command, and when the task is completed, the test performance will be recorded separately for the tested hand as the time to complete the task. Below is the tasks.

Task 1: Stack 4 checkers, Task 2: Card flipping, Task 3: Collecting objects, Task 4: Writing,Task 5: Eating, Task 6: Moving Light Objects, Task 7: Moving Heavy Objects

This device is a device consisting of a square platform and a storage box. There are 9 holes in the square-shaped area (12.7x2cm) and 9 cylinders suitable for these holes. The diameter of the holes is 0.71 cm, the diameter of the cylinders is 0.64 cm, the length is 3.2 cm, the distance between the holes is 3.2 cm, the hole depth is 1.3 cm and the size of the storage box is 13x13 cm. During the test, the patient sits at the table with the 9-hole board, and the patient is asked to quickly take the 9 cylinders from the storage box, place them in the holes in random order, and quickly remove them from the holes without taking a break and place them in the storage box. Meanwhile, time is measured in seconds with a stopwatch. The test is performed 2 times consecutively for both hands and the average of the result is taken. The total test score is calculated by taking the average of the scores for both hands.

It includes swelling and tenderness in 28 joints including the proximal interphalangeal joint, metacarpophalangeal joint, wrist, elbow, shoulder and knee joints, erythrocyte sedimentation rate (ESR) value, and global evaluation of the patient (VAS 0-100 mm). The DAS 28 value is calculated using a special formula:

DAS28 = (0.56 x √ Number of Tender Joints) + (0.28 x √ Number of Swollen Joints) + (0.70 x Ln (ESR value)) + (0.014 x Patient global assessment) High score; indicates high disease activity. Values higher than 5.1 indicate high disease activity, values between 3.2\
