Balance disorders are very common in patients with Parkinson's, and these disorders significantly affect the patient's body alignment and participation. Especially during walking, balance disorders occur, resulting in falls, disability and injury in the advanced stage of the disease. As a result of these losses in patients, falls can be seen, and the severity of disability that increases with age affects the quality of life of individuals by affecting their living in their own homes.~Dubousset Functional Test (DFT); A conceptually practical four-component assessment test has been proposed by Dr. Jean Dubousset to assess the functional capacity of adult individuals. The validity of the test was made in individuals with spinal deformity. DFT; It consists of four components: getting up from a chair without arms and walking 5 meters forward and backward, descending and climbing steps, transition from standing to sitting on the ground, and the dual task test in which the individual walks while counting down from 50 at the same time~In the literature, there are many scales that evaluate balance and functional performance in Parkinson Disease. However there is no validity and reliability study of Dubousset Function Test developed to evaluate balance and functional performance of Parkinson Disease. For this reason, the aim of study is to examine the validity and reliability of Dubousset Function Test in Parkinson Disease.
In order to achieve collaborative patient-centered rehabilitation in Parkinson's disease, detailed evaluation of walking and balance in evaluating the perceived difficulty in daily life is important to evaluate the progression of the disease and its response to treatments.~In the literature, there are many scales that evaluate balance and functional performance in Parkinson Disease. However there is no validity and reliability study of Dubousset Function Test developed to evaluate balance and functional performance of Parkinson Disease. For this reason, the aim of study is to examine the validity and reliability of Dubousset Function Test in Parkinson Disease.
