Whole-Body Vibration in Parkinson Disease

The aim of this study is to evaluate the effects of different frequencies of Whole Body Vibration (WBV) application on balance, gait, cognitive functions, and dual-task performance in patients with Parkinson's disease. Study Hypotheses: H0.1 - There is no effect of different frequencies of WBV application on balance performance in patients with Parkinson's disease. H1.1 - There is an effect of different frequencies of WBV application on balance performance in patients with Parkinson's disease. H0.2 - There is no effect of different frequencies of WBV application on gait performance in patients with Parkinson's disease. H1.2 - There is an effect of different frequencies of WBV application on gait performance in patients with Parkinson's disease. H0.3 - There is no effect of different frequencies of WBV application on cognitive functions in patients with Parkinson's disease. H1.3 - There is an effect of different frequencies of WBV application on cognitive functions in patients with Parkinson's disease. H0.4 - There is no effect of different frequencies of WBV application on dual-task performance in patients with Parkinson's disease. H1.4 - There is an effect of different frequencies of WBV application on dual-task performance in patients with Parkinson's disease. H0.5 - There is no effect of different frequencies of WBV application on reaction time in patients with Parkinson's disease. H1.5 - There is an effect of different frequencies of WBV application on reaction time in patients with Parkinson's disease. H0.6 - There is no significant difference between medium-frequency and low-frequency WBV in terms of balance performance in patients with Parkinson's disease. H1.6 - There is a significant difference between medium-frequency and low-frequency WBV in terms of balance performance in patients with Parkinson's disease. H0.7 - There is no significant difference between medium-frequency and low-frequency WBV in terms of gait performance in patients with Parkinson's disease. H1.7 - There is a significant difference between medium-frequency and low-frequency WBV in terms of gait performance in patients with Parkinson's disease. H0.8 - There is no significant difference between medium-frequency and low-frequency WBV in terms of cognitive functions in patients with Parkinson's disease. H1.8 - There is a significant difference between medium-frequency and low-frequency WBV in terms of cognitive functions in patients with Parkinson's disease. H0.9 - There is no significant difference between medium-frequency and low-frequency WBV in terms of dual-task performance in patients with Parkinson's disease. H1.9 - There is a significant difference between medium-frequency and low-frequency WBV in terms of dual-task performance in patients with Parkinson's disease. H0.10 - There is no significant difference between medium-frequency and low-frequency WBV in terms of reaction time in patients with Parkinson's disease. H1.10 - There is a significant difference between medium-frequency and low-frequency WBV in terms of reaction time in patients with Parkinson's disease.
