Effect of acceptance and commitment therapy on fear of falling and physical activity in Parkinson's disease: a...

This study aimed to evaluate the efficacy of acceptance and commitment therapy (ACT) in reducing the fear of falling (FOF) and promoting physical activity in individuals diagnosed with Parkinson's disease (PD).

This is a prospective, multicentre, rater-blinded and randomised controlled trial. Patients with PD and a history of falls will be randomly assigned to either an 8-week ACT intervention group or a control group receiving standard care. The primary outcomes measured will include FOF assessment using the Falls Efficacy Scale-International and physical activity levels measured via wearable sensor devices. Secondary outcomes will encompass the assessment of motor function, balance and fall frequency using the Movement Disorder Society Unified Parkinson's Disease Rating Scale, Berg Balance Scale and Timed Up and Go test. Objective measures of balance and physical activity will be obtained through static posturography and wearable sensors over a 3-day period, both before and after the intervention. Data will be analysed using mixed-effects models to evaluate the impact of ACT on FOF and physical activity.

We hypothesised that ACT would lead to a significant reduction in FOF and an increase in physical activity levels compared with standard care. Additionally, this study will also examine the relationship between reduced FOF and improvements in balance and motor function. Our results will provide valuable evidence to support the effectiveness of ACT in reducing FOF and promoting physical activity among patients with PD, and if validated, ACT could be recommended as a beneficial intervention to enhance the quality of life and reduce fall-related morbidity in patients with PD.
