Not Applicable
Recruiting
Conditions
Parkinson Disease
Interventions
Behavioral: High intensity endurance exercise
Behavioral: Stretching exercise
Behavioral: Virtual reality (VR)-based gaming
Registration Number
NCT06133283
Lead Sponsor
The University of Texas Health Science Center at San Antonio
Brief Summary

This study aims to determine the effects of aerobic exercise as a primer to add-on virtual reality (VR)-based rehabilitation on balance, postural control and neuroplasticity (ability of brain to adapt in structure and function) in individuals with Parkinson's disease (PD). This study will utilize two groups - one group will receive the exercise and VR, while the other group will receive stretching exercise and VR over eight weeks. The study team will administer outcomes at baseline, post-intervention (8 weeks) and follow-up (6 weeks after post-assessment).

Detailed Description

This study will enroll individuals diagnosed with Parkinson's disease who will be randomly assigned to 2 groups: 1) high intensity endurance exercise and virtual reality (experimental) or 2) stretching and virtual reality (control) for eight weeks (three sessions, thrice weekly). Outcomes will include balance and gait measures, blood-based biomarkers, neuroplasticity measures (assessed by transcranial magnetic stimulation), spinal reflex excitability (measured by H reflex) and quality of life.

Primary Outcome Measures
NameTimeMethod
BalanceBaseline, post (8 week), follow-up (14 weeks)

Balance will be tested with the Mini Balance Evaluation Systems Test(miniBESTest), involving 14 different tasks including the timed up and go test to assess static and dynamic balance. Scores range from 0 to 28 with higher scores suggesting better balance.

Secondary Outcome Measures
NameTimeMethod
Brain derived neurotrophic growth factor (BDNF)Baseline, post (8 week), follow-up (14 weeks)

Blood sample will be obtained for measuring circulating levels of brain derived neurotrophic growth factor (BDNF).

Corticomotor excitabilityBaseline, post (8 week), follow-up (14 weeks)

Corticomotor excitability for the tibialis anterior motor representations will be measured with single and paired pulse transcranial magnetic stimulation (TMS).

Spatiotemporal gait parametersBaseline, post (8 week), follow-up (14 weeks)

Spatiotemporal measures of gait will be acquired with the GAITRite™ gait mat.

Spinal reflex excitabilityBaseline, post (8 week), follow-up (14 weeks)

H reflexes will be recorded for quantifying spinal reflex excitability. The H wave amplitude will be expressed as a % of the M wave amplitude (H/M ratio).

EnduranceBaseline, post (8 week), follow-up (14 weeks)

The 6-minute walk test will be used as a measure of cardiovascular endurance

Postural stabilityBaseline, post (8 week), follow-up (14 weeks)

Postural stability will be assessed by the Biodex Balance System.

Parkinson's Disease Questionnaire (PDQ-39)Baseline, post (8 week), follow-up (14 weeks)

The Parkinson's disease questionnaire (PDQ-39) is a self report questionnaire that will be used to evaluate quality of life. The questionnaire consists of 39 items with each item being rated on a 5-point scale. Lower scores suggest higher quality of life.

Parkinson's Disease Cognitive Rating Scale (PD-CRS)Baseline, post (8 week), follow-up (14 weeks)

The Parkinson's disease cognitive rating scale will be used to test frontal subcortical tasks such as attention, working memory, verbal fluency and posterior cortical tasks such as confrontation naming and copying a clock. Scores range from 0 - 134 and higher scores suggest better cognitive function.
