Whole-body vibration (WBV) has emerged as a potential rehabilitative approach, but its effects on muscle tone and thoracic kyphosis in PD patients remain underexplored. Objective: This study aimed to evaluate the immediate and short-term effects of an 8-week WBV training program combined with usual care on thoracic kyphosis, trunk muscle tone, stiffness, elasticity, and gait functionality in individuals with PD. Methods: A parallel randomized controlled trial was conducted with 46 PD patients, randomly assigned to either a real WBV group or a sham WBV group. Participants underwent two treatment sessions weekly, including usual therapy followed by real or sham WBV. Primary outcomes included thoracic kyphosis measured using the Goniometer-Pro app and viscoelastic muscle properties assessed with the MyotonPRO device. Secondary outcomes included the Timed Up and Go (TUG) test. Measurements were taken at baseline, immediately post-intervention, and after a 12-week follow-up. Results: The real WBV group showed a significant reduction in thoracic kyphosis and improvements in muscle tone, stiffness, and elasticity, particularly in the lumbo-thoracic spine. No significant changes were observed in the TUG test. The sham WBV group exhibited some improvements, likely due to placebo effects. Conclusions: WBV combined with usual therapy can enhance postural control and muscle properties in PD patients, particularly in the lower spine. These findings suggest WBV as a beneficial complementary therapy for PD, though high dropout rates should be considered in future studies.application/x-vnd.spss-statistics-spdengAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Enfermedad de ParkinsonVibración de cuerpo enteroCifosis torácicaPropiedades muscularesParkinson’s DiseaseWhole Body VibrationThoracic kyphosisMuscle propertiesinfo:eu-repo/semantics/datasetinfo:eu-repo/semantics/openAccesshttps://doi.org/10.12795/11441/172592
