The effects of free dance versus hatha yoga on quality of life and motor and non-motor symptoms in people with Parkinson's disease: protocol study for a randomized clinical trial

Objective: To describe a protocol comparing the effects of free dance, hatha yoga, and a control group on quality of life, motor and non-motor symptoms in people with Parkinson's disease (PwP). Methods: This is a randomized three-arm study. Inclusion criteria will be people with clinically diagnosed Parkinson's disease (PD), ≥ 45 years old, and in stages I to IV of the Hoehn and Yahr Disability Scale (HY). Who do not reach the cut-off point of the Montreal Cognitive Assessment (MoCA) and classified in stage V of the HY will be excluded. The interventions will last 60 minutes, twice a week, progressing from light to vigorous intensity. The primary outcome will be quality of life assessed by the Parkinson's Disease Questionnaire (PDQ39). Secondary outcomes will include the Unified Parkinson's Disease Rating Scale (UPDRS), the evaluation of motor and physical function such as shoulder and hip range of motion (goniometer), cardiorespiratory fitness (six-minute walk test), balance (MiniBESTest), as well as non-motor aspects such as anxiety (Beck Anxiety Inventory), self-esteem (Rosenberg Self-Esteem Scale), cognition (MoCA), hope (Herth Hope Scale), fecal incontinence (Fecal Incontinence Quality of life), urinary incontinence (International Consultation on Incontinence Questionnaire - Short Form), and depressive symptoms (Beck Depression Inventory). Data will be collected at baseline and post-intervention. Discussion: If study interventions are deemed effective compared to standard of care (i.e. control group), the present study will advance current knowledge on non-pharmacological therapeutic strategies for People with Parkinson.
