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

Direct education of the patient in the field of self-care, counseling and instruction on independent exercise, use of medical equipment or devices, also at home.

Assessment of the patient's functional status: 10 Meter Walk (10 MW) Test, Tinetti Test, New Freezing of Gait Questionnaire (NFOG-Q), History of Falling Questionaire, Timed up and go (TUG), TUG - countdown from 100 to 80, TUG - cup half-filled with water carried in the right and left hand, TST - 10 s standing in a tandem position, 180 Tandem Pivot Test, TWT - Tandem Walking Test, Functional Reach test, Functional strength test, TEST Six Minute Walk (6MWT), Berg Balance Scale, Treadmill Gait Analysis, Platform Stabilometry Test.

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).

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).

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).

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).

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).
