In individuals diagnosed with Parkinson's disease, not being able to stand up especially after falling problems and staying in supine position cause loss of motivation and decrease in quality of life for patients. In order to prevent this problem in neurological diseases, it must be evaluated and treated by working functionally as a result of this evaluation. Parkinson's patients who will participate in the study will be referred from SANKO University Sani Konukoğlu Application and Research Hospital Neurology Polyclinic. The evaluations of the patients referred from the neurology polyclinic will be carried out in SANKO University Physiotherapy and Rehabilitation Department Research Laboratory. Socio-demographic information of the included patients will be obtained. Then, the supin to stand test will be used to measure the transition time from the supine position to the standing position and mobility status, the Activity-specific balance safety scale (ABC) for fear of falling, the Berg Balance Scale for balance assessment and the timed get up and walk test, 9-hole peg test for upper extremity functionality, manual muscle testing device for muscle strength of Dorsi flexor and Plantar flexor muscle groups in the ankle, Parkinson's Disease Quality of Life Questionnaire (PHA-39) for quality of life. The evaluations to be applied will be carried out by Dr. Lecturer. Member Hakan Polat will be carried out by Hakan Polat. Apart from the supine to stand test, the other tests to be performed are tests that evaluate the parameters that an individual should have for the transition from supine to standing position. These parameters are balance, muscle strength, ability to stand up without sitting, fine motor skill ability. Supin to stand test will be re-evaluated by a different physiotherapist in SANKO University Physiotherapy and Rehabilitation Department Research Laboratory after 1 week.
