The modified DMI program consists of 4 stages: lateralization, open motor imagery including action observation training, mirror therapy and upper extremity functional exercise. The program will be implemented for 8 weeks, 3 days a week, under the supervision of a physiotherapist. Lateralization training will be applied in the first 2 weeks. Motor imagery training will be implemented in the 3rd and 4th weeks. For the second stage, the application will be combined with action observation training. As the 3rd stage, mirror therapy will be performed in the 5th and 6th weeks. The participant will be asked to perform some exercises while watching the reflection of the intact extremity in the mirror. In the final stage, they will be asked to physically perform upper extremity functional exercises. The total treatment time will be 40-50 minutes, with patients receiving 20-30 minutes of modified grade motor imagery and 20 minutes of conventional treatment.

The DMI program consists of 3 stages: lateralization, open motor imagery and mirror therapy. The program will be implemented for 8 weeks, 3 days a week, under the supervision of a physiotherapist. First, lateralization training will be applied. In the second stage, motor imagery training will be applied. This phase will be carried out in a quiet environment by asking the participants to fully focus on the visualization of the movements. Two methods will be used for the imagined movements. In particular, visuals of the shoulder and hand used in the lateralization phase will be used to visualize movements related to the normal movement of the upper extremity. Participants will also be asked to imagine different activities in daily life. In the final stage, mirror therapy will be applied. The participant will be asked to perform some exercises while watching the reflection of the intact extremity in the mirror.

A modified form of graded motor imagery training and conventional rehabilitation will be applied.

The scale is a widely used, reliable and valid test to evaluate paretic upper extremity motor impairment in stroke patients. From this scale, where each parameter is scored between 0-2 points, a maximum score of 66 can be obtained, and high scores indicate good motor functions.

WMFT is used to evaluate motor skill in patients with upper extremity motor dysfunction. The 15 functional activities evaluated are scored between 0-5 points and the functional skill score is calculated by taking the average of the total score. Higher scores indicate better functional ability. In the performance time section, how long each activity took is recorded. A maximum of 120 seconds is allowed to complete an activity. If the activity cannot be completed within this time, the performance time is recorded as 120 seconds.

MBI, which is used to measure the independence of individuals in daily living activities, emerged by modifying the Barthel Index. MBI includes 10 items related to activities of daily living. Total score is between 0-100. As the score increases, individuals' independence in daily living activities increases.

It consists of a total of 49 items for 12 subcategories (mobility, fitness, upper extremity functionality, work/productivity, mood, self-care, social roles, family roles, language, vision, thinking and personality) that evaluate the quality of life of individuals with stroke. The higher the total score, the better the stroke individual's quality of life.

Right/left lateralization performance of the upper extremity will be evaluated with the "Recognise™" application developed by the Neuro Orthapedic Institute. The "Recognise™ Hand" and "Recognise™ Shoulder" sections of this application and the "Vanilla" part of these sections will be used. Accuracy rates and reaction time in the application will be recorded. An increase in the accuracy rate indicates that lateralization performance has improved.
