The physiotherapy group will take a physiotherapy program for 3 sessions per week, 60 minutes per day, for a total of 8 weeks. The program will consist of functional exercises for trunk, upper and lower extremities.

In addition to the functional exercises individuals will receive visual-motor training targeting the upper extremity. This training will be conducted using the Light Trainer, a branded light-based training system. The light training system consists of 6 laser sensor-equipped blue, red, and green light emitters.The system is operated through a smartphone application.The training will utilize four different games, progressing from easy to difficult: Sequential, random standard, multiple light, and different color. Participants will receive training via a 12-minute session utilizing the Light Trainer device.

The physiotherapy group will take a physiotherapy program for 3 sessions per week, 60 minutes per day, for a total of 8 weeks.

The program will consist of functional exercises for trunk, upper and lower extremities (same as experimental group).

Functional reaching activities at the table in a sitting position, ball sliding on the wall in a standing position, touching different targets on the wall in a standing position and drawing shapes on the wall in a standing position will also added to the program.

Individuals in both groups will receive a physiotherapy program for 3 sessions per week, 60 minutes per day, for a total of 8 weeks.The study consists of two groups: the experimental group and the control group. Both groups will receive a physiotherapy program of 3 sessions per week, each lasting 60 minutes, for a total of 8 weeks. Within the 60-minute physiotherapy session, patients from both groups will undergo 30 minutes of exercises based on the Neurodevelopmental Treatment (NDT) method. In addition, a 12-minute training session will be conducted using a light-based trainer system (Light Trainer® Exercise System).

Modified Ashworth Scale (MAS) will be used to evaluate the muscle tone of the **shoulder, elbow, wrist, and finger flexors** in post-stroke patients. This scale will be applied both as part of the **initial assessment** for determining eligibility and to evaluate the **effectiveness of the intervention** by comparing pre- and post-treatment scores. MAS grades muscle tone on a 6-point ordinal scale.Each measurement will be performed twice. Data will be entered into the statistical database both as ordinal values (0 to 4) and using a coding system for further analysis. Patients will be evaluated pre- and post-treatment using the MAS.

The Fugl-Meyer Motor Assessment Scale is a performance-based motor impairment scale developed to evaluate recovery in individuals with stroke. This scale includes subtests that assess upper and lower extremity functions, balance, sensation, and posture. In our study, the upper extremity gross and fine motor functions of patients will be assessed using the Fugl-Meyer Upper Extremity (FM-UE) Assessment Scale. The maximum score that can be obtained in the assessment is 66, with higher scores indicating better motor function. Patients will be evaluated pre- and post-treatment using the Fugl-Meyer Assessment Scale.

The Wolf Motor Function Test (WMFT) is a test developed to evaluate motor skills in patients with moderate to severe upper extremity motor deficits The original version was developed by Wolf and colleagues. In our study, the modified version developed by Morris and colleagues will be used.Data will be collected for 15 activities in two areas: "functional ability" and "performance time". The duration of the test is 30-45 minutes.Each activity will be rated by the physiotherapist using a scale of 0 to 5 based on the functional ability section, where:0 = "The affected hand is not used at all during the activity",5 = "Normal movement".The average score for functional ability will be calculated, and based on this, the patient will receive a score between 0 and 5, with higher scores indicating good functional ability.The performance time will be recorded in seconds.The maximum time given to complete an activity is 120seconds.Patients will be evaluated pre- and post-treatment using the WMFT

The Stroop test is a cognitive assessment that evaluates executive functions and measures attention, the inhibition of inappropriate automatic responses, and perception under disruptive influence. The Stroop effect not only measures executive functions but also assesses processing speed, automatic, and parallel processing. The Stroop effect occurs when there is a conflict between the color name written and the color used to write it. When the colors are different, reading the word becomes slower compared to reading words that are written in the same color, and the difference between these two speeds is referred to as the Stroop effect. The Stroop effect not only measures executive functions but also assesses processing speed, automatic, and parallel processing. A longer completion time and a higher error count indicate weak cognitive flexibility. Patients will be evaluated pre- and post-treatment using the Stroop test.
