Effect of Physical Activity on the Course of Parkinson's Disease in Patients With Bilateral DBS-STN Stimulation. (EPA-DBS)

October 1, 2026 updated by: Medical University of Warsaw

Effect of Physical Activity on the Course of Parkinson's Disease in Patients With Bilateral DBS-STN Stimulation - a Randomized Controlled Trial.

Parkinson's disease is a common, progressive neurodegenerative disorder. The degeneration of dopaminergic neurons is associated with characteristic clinical symptoms such as tremor, rigidity, slowness of movement (bradykinesia) and postural instability. Subthalamic nucleus deep brain stimulation (DBS-STN) is a recognized and widely used method of treating advanced stages of Parkinson's disease. It improves clinical symptoms such as tremor, rigidity and slowness of movement (bradykinesia). This method has limited application for late motor and non-motor symptoms such as: akinesia, postural instability, gait, including the phenomenon of "freezing", recurrent falls, balance and dysarthria. These symptoms reduce the quality of life of patients and make them dependent on their caregivers. There is a clear need to develop additional forms of therapy that complement deep brain stimulation in controlling late motor and non-motor symptoms.

Physical activity is a commonly used and recommended form of therapy for patients with Parkinson's disease and a complement to pharmacological therapy, improving gait, balance and quality of life. However, there are no clear recommendations including patients after implantation of DBS-STN stimulators to the group undergoing physiotherapy. To this day, only one clinical trial has been registered assessing the effect of physiotherapy on balance and gait in patients with DBS-STN.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Part III: Motor Examination
Time Frame: 2 years

Change in the full Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Part III: Motor Examination, score in the full ON medication/DBS state from baseline to study completion, comparing the control and study groups, with subsequent study time points also reported. Part III assesses the severity of motor signs of Parkinson's disease. The total score ranges from 0 to 132, with 0 indicating no motor impairment and higher scores indicating greater motor impairment (i.e., a worse outcome).

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Tinetti Performance-Oriented Mobility Assessment (POMA)
Time Frame: 2 years

Change in the full Tinetti Performance-Oriented Mobility Assessment (POMA), also known as the Tinetti Mobility Test, total score in the ON medication/DBS state before and after study completion, comparing the control and research groups, with subsequent study time points also reported. The POMA assesses balance and gait/mobility. The total score ranges from 0 to 28 points (balance: 0-16; gait: 0-12), with higher scores indicating better mobility, gait, and balance function (i.e., a better outcome).

2 years
New Freezing of Gait Questionnaire (NFOG-Q)
Time Frame: 2 years

Change in the full New Freezing of Gait Questionnaire (NFOG-Q) total score in the ON medication/DBS state before and after study completion, comparing the control and research groups, with subsequent study time points also reported. The NFOG-Q is a patient-reported measure assessing the severity of freezing of gait and its impact on daily life in people with Parkinson's disease. The total score ranges from 0 to 28 points, with 0 indicating no freezing of gait and higher scores indicating greater severity and impact of freezing of gait (i.e., a worse outcome).

2 years
Berg Balance Scale (BBS)
Time Frame: 2 years

Change in the full Berg Balance Scale (BBS) total score in the ON medication/DBS state before and after study completion, comparing the control and research groups, with subsequent study time points also reported. The BBS is a 14-item performance-based measure of functional balance. Each item is scored from 0 to 4, giving a total score ranging from 0 to 56 points, with higher scores indicating better balance and functional performance (i.e., a better outcome).

2 years
Montreal Cognitive Assessment (MoCA)
Time Frame: 2 years

Change in the full Montreal Cognitive Assessment (MoCA) total score in the ON medication/DBS state before and after study completion, comparing the control and research groups, with subsequent study time points also reported. The MoCA is a cognitive screening assessment of multiple cognitive domains, including executive function, visuospatial abilities, attention, memory, language, and orientation. The total score ranges from 0 to 30 points, with higher scores indicating better cognitive performance (i.e., a better outcome).
