Evaluation of the Effects of Aquatic Therapy on Activities of Daily Living, Walking, Balance, Posture, Pain, and Depression in Parkinson's Patients

Parkinson's Disease (PD) is a progressive neurodegenerative disorder characterized by motor symptoms such as bradykinesia, tremors, and postural instability, as well as various non-motor symptoms. Conventional land-based rehabilitation is standard; however, aquatherapy-utilizing water's buoyancy, hydrostatic pressure, and viscosity-offers a promising alternative to improve balance and mobility while reducing fall risks. This study aims to evaluate the effects of aquatherapy on gait, balance, posture, freezing of gait, activities of daily living (ADL), pain, and depression in Turkish PD patients. This is a prospective, single-blind, randomized controlled trial involving 42 patients at Ankara City Hospital. Participants will be divided into two groups: * Group 1 (Control): Home-based exercise program (5 days/week for 6 weeks). * Group 2 (Intervention): Home-based exercises plus supervised aquatherapy (3 sessions/week, 45 minutes each, in a 30-32°C pool). The study utilizes high-tech objective measurements and validated scales: * Gait \& Posture: Zebris Gait Analysis (spatiotemporal parameters) and Diers Formetric 4D (topographical posture analysis). * Balance: HUR-Smart Balance device and the Berg Balance Scale. * Clinical Scales: PDQ-39 (quality of life), Freezing of Gait Questionnaire, Falls Efficacy Scale, MMSE (cognitive), Beck Depression Inventory, and VAS (pain). This research is noteworthy as the first aquatherapy study among Turkish PD patients to utilize a large sample size and standardized aquatic exercise protocols. It seeks to provide a comprehensive analysis of both motor and non-motor improvements, potentially establishing aquatherapy as a superior adjunctive treatment for enhancing functional independence in Parkinson's patients.
