Summary

The aim of this methodological study was to investigate the Turkish validity and reliability of the Parkinson's Disease Dyskinesia Scale (PDYS-26).The scale evaluates choreic dyskinesia.Measures the impact of dyskinesia on activities of daily living in patients with Parkinson's disease. Hypotheses of the Study: * Parkinson's Disease Dyskinesia Scale (PDYS-26) is reliable in Turkish. * Parkinson's Disease Dyskinesia Scale (PDYS-26) is valid in Turkish. To determine the validity of dyskinesia; * Tampa Kinesiophobia Scale, * Mini BesTest, * Activity Specific Balance Safety Scale (ABC) and * Parkinson's Disease Questionnaire-39 will be evaluated.

Detailed description

In Parkinson's disease, a neurodegenerative disorder affecting the peripheral and central nervous system, dyskinesia is a common symptom that occurs as disease processes progress and leads to disability. The term dyskinesia is a general term that covers many movement disorders. In general, it can be defined as mild to severe abnormal and involuntary muscle movements. In individuals with Parkinson's disease, it is a natural consequence of the neurodegenerative process and a motor complication of the gold standard L-dopa. Assessment of dyskinesia in Parkinson's patients is important for the implementation of appropriate medical, surgical and rehabilitation protocols. There are few scales and patient diaries that clinically assess the effect of interventions for dyskinesia. At the same time, there are deficiencies related to the reliability and validity studies of these existing scales in different languages. Therefore, limitations may arise in the assessment of dyskinesia. For this purpose, our study aims to investigate the reliability and validity of the Parkinson's Disease Dyskinesia Scale (PDYS-26) in Turkish in patients diagnosed with 130 idiopathic Parkinson's patients.In the study, the Parkinson's Disease Dyskinesia Scale (PDYS-26) will be translated into Turkish with the "back translation" method and will be finalized after the approval of the commission consisting of relevant health professionals. The final version of the scale will be applied to Parkinson's patients. To determine the validity of dyskinesia; Tampa Kinesiophobia Scale, Mini BesTest Activity Specific Balance Safety Scale (ABC) and Parkinson's Disease Questionnaire-39 will be evaluated.

Interventions

Type	Name	Description
OTHER	Turkish version of the Parkinson's Disease Dyskinesia Scale (PDYS-26)	The Turkish adaptation of the Parkinson's Disease Dyskinesia Scale (PDYS-26) is administered to individuals diagnosed with Parkinson's disease who have a dyskinesia score of ≥1 based on the Unified Parkinson's Disease Rating Scale (UPDRS) dyskinesia item. The scale is used to evaluate dyskinesia severity and assess its clinical applicability in Turkish-speaking populations.
