Study Aim

This observational study aims to measure spinal mobility in individuals with Parkinson's disease, both with and without Temporomandibular Disorders (TMD), using tests such as the Modified-Modified Schober Test, Tragus-to-Wall Distance, Occiput-to-Wall Distance, and Intermalleolar Distance.

Actual date on which the first participant was enrolled.

This study focuses on individuals with Parkinson's disease (PD) and explores the connection between their spinal mobility, axial rigidity (stiffness in the midsection of the body), and a condition called Temporomandibular Disorders (TMD), which affects the jaw joint. The goal is to understand if there are differences in spinal mobility, axial rigidity, and fear of movement (kinesiophobia) between PD patients with and without TMD. The study also aims to investigate if there's a biomechanical link between TMD and these aspects in PD patients. The study takes place at the Neurology Outpatient Clinic of Hatay Mustafa Kemal University Research and Training Hospital. Participants, aged 40-75, diagnosed with PD, and meeting specific criteria will undergo a single session of evaluations. These include assessing the presence of TMD, measuring jaw range of motion, spinal mobility, axial rigidity, posture, and kinesiophobia. Various tests and measurements will be used, such as the Fonseca Anamnestic Index, the Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), and the Tampa Scale for Kinesiophobia. The results are expected to provide insights into how spinal mobility, axial rigidity, and kinesiophobia might impact the temporomandibular system in PD, potentially guiding assessment and rehabilitation strategies.
