ClinConnect Summary

This clinical trial is studying a tool called the Parkinson's Disease Dyskinesia Scale (PDYS-26) to see if it works well in Turkish-speaking patients with Parkinson's disease. The PDYS-26 helps doctors understand how dyskinesia, which are involuntary movements or twitches, affects daily activities and the overall quality of life for people living with Parkinson's. This study will check if the scale is reliable (meaning it gives consistent results) and valid (meaning it accurately measures what it is supposed to measure) when used in Turkish.

To be eligible for the trial, participants must be diagnosed with idiopathic Parkinson's disease (the most common form), be in stages 1 to 3 of the disease, and show some signs of dyskinesia. Participants will complete various assessments, including the PDYS-26, and may also answer questions related to balance and daily living activities. The trial is currently recruiting participants of all genders, and those interested should be willing to join the study and meet the inclusion criteria. If you're considering participating, this could be a valuable opportunity to help improve how dyskinesia is assessed in Turkish-speaking patients.
