A pilot study of a 12-week community-based boxing program for Parkinson?s disease

Introduction: Community-based exercise programs for Parkinson's disease (PD) have gained popularity. Our understanding of such programs on non-motor features is limited. We characterized the effect of a 12-week community-based boxing exercise program on motor and non-motor symptoms in people with Parkinson's dis-ease (PwPD). Methods: In this prospective observational study, PwPD underwent a 12-week community-based boxing program (2 sessions per week, for a total of 24 sessions). The following assessments were performed by a movement disorders neurologist at baseline and after completion of the program: MDS-Unified Parkinson's Disease Rating Scale part III (MDS-UPDRS III) in a modified version since assessments were performed virtually due to COVID-19 pandemic, MDS Non-Motor Rating Scale (MDS-NMS), Hamilton Depression Rating Scale (HDRS), Lilli Apathy Rating Scale (LARS), Parkinson's Disease Questionaire-39 (PDQ-39), and Schwab and England Activities of Daily Living scale (SE-ADL). Pre-and post-assessments were compared using Wilcoxon signed rank test; only partic-ipants who completed the program and both assessments were analyzed. Results: A total of 14 PwPD agreed to be a part of the study and completed assessments. All participants were ambulatory and functionally independent at baseline. Total non-motor feature severity (MDS-NMS, p = 0.0031), depression (HDRS, p = 0.015), and motor features (MDS-UPDRS PART 3 modified, p = 0.023) all improved significantly after the intervention. Scales on apathy (LARS, p = 0.29), Parkinson's disease-specific health related quality (PDQ-39, p = 0.093), and activities of daily living (SE-ADL, p = 0.32) did not demonstrate significant change. Conclusion: PwPD who participated in a community-based, pilot boxing program showed improvements in motor exam and non-motor symptoms.
