Effects of Whole Body Vibration Versus Proprioceptive Neuromuscular Facilitation Pattern With Rhythmic Based Training on Clinical Outcomes in Patients With Parkinson's Disease.

This study has important clinical, academic, and practical relevance in neuromuscular rehabilitation. Clinically, it aims to identify effective and tolerable rehabilitation strategies for individuals with Parkinson's disease by comparing whole-body vibration therapy with proprioceptive neuromuscular facilitation (PNF) patterns combined with rhythmic-based training, thereby supporting evidence-based physiotherapy practice and improving patient adherence. Academically, it contributes to the limited literature on comparative effectiveness of these interventions and incorporates patient-centered outcomes such as exercise perception, which are often underreported. From a practical and societal perspective, identifying a more acceptable and effective approach may enhance long-term participation in rehabilitation, potentially slow disease progression, improve quality of life, and reduce the overall healthcare burden associated with Parkinson's disease.

Inclusion Criteria: * Age between 40 and 60 years. * Patients of both genders (male and female). * Parkinson's disease severity at Hoehn and Yahr (H\&Y) stage 2 and 3. * Ability to walk independently for 6 minutes without an assistive device. * Score greater than 40 on the Berg Balance Scale. Exclusion Criteria: * Presence of impaired Cognition. * Significant Orthopedic and Musculoskeletal conditions that limit the adherence to exercise and WBV requirements. * Other medical conditions like thrombosis, cardiovascular conditions and medical implants that are contradicted for WBV.
