The participants will test the application for up to 4 weeks and then report on the user experience. A standardized questionnaire (NRS 2002) will be used for this purpose. URI-Soca will recruit at least 7 patients, inpatients or outpatients for motor rehabilitation of upper extremities. The tasks will be carried out at the occupational therapy and physiotherapy units of URI-Soca for up to 4 weeks, 3 times a week. At the same time, expert analysis (neurologist, physiotherapist, occupational therapist, engineer) of the measured data (kinematics, the results achieved) will be performed and clinical tests (Unified Parkinson's Disease Rating Scale - UPDRS, Jebsen Tailor Functional Test and PD Questionnaire 39) will be carried out before and after the exercise program. At the same time, the system will be adapted for home use (by at least 1 patient), and then a study will be conducted with other patients. These participants will receive the system for home use for up to 60 days. The data will be accessed remotely over the Internet, so the objective evaluation can be carried out promptly. The clinical test will be conducted before exercise and after exercise, i.e., at the beginning and at the end of the observation period.
