The intervention group consisted of 42 patients who received standard physical therapy and occupational therapy for 90 minutes per day, five days per week. Additionally, these patients underwent training with the ArmeoPower robotic system for 45 minutes per day, five days per week.

The control group comprised 42 patients who participated in standard physical therapy and occupational therapy for 90 minutes per day, five days per week. In addition, these patients were instructed to engage in home-based practice for 45 minutes per day, five days per week, guided by direct instructions and exercise leaflets provided by the therapists.

ArmeoPower is a robotic rehabilitation device developed by Hocoma, designed to assist patients with impaired upper limb motor functions following conditions such as stroke or neurological injuries. The device features an exoskeleton that supports and tracks movements of the arm and hand, utilizing motor-assisted motion based on the principle of "adaptive support," which adjusts assistance levels according to the patient's capabilities. ArmeoPower integrates interactive exercises, often in the form of engaging games, to enhance patient motivation and maintain focus during therapy sessions. It also collects and tracks performance data, enabling clinicians to evaluate progress over time. This device is widely used in rehabilitation centers and hospitals to improve muscle control, strength, and range of motion in patients recovering from severe motor impairments.

The Fugl-Meyer Assessment for Upper Extremity (FMA-UE) is a standardized clinical test used to evaluate the recovery of upper limb motor function in patients after a stroke. This scale is widely recognized for its reliability and sensitivity in assessing motor recovery during rehabilitation. The test comprises 8 assessment domains with a total of 33 items, and the maximum score achievable is 66 points. Based on the total score, recovery is categorized into four levels: good (56-66 points), indicating near-complete recovery of motor function; fair (42-54 points), reflecting moderate recovery; average (22-40 points), representing limited recovery with partial functionality; and poor (0-20 points), signifying severe motor impairment

The Action Research Arm Test (ARAT) is a clinical scale designed to assess upper limb function, encompassing both gross motor skills and fine motor skills of the hand and fingers. The test evaluates four primary categories of movement: grasping large objects, grasping medium-sized objects, pinching small objects, and gross arm movements. The maximum score for the ARAT is 57 points, with recovery outcomes classified into three levels: good recovery (57 points), indicating full restoration of function; moderate recovery (10-56 points), reflecting partial functional ability; and poor recovery (<10 points), signifying severe impairment.
