Enhancing Modulation Effects of Baduanjin Through Neuromodulation for Knee OA
Study Details
Study Description
Brief Summary
This study will combine brain imaging and neuromodulation tools to investigate the underlying neurobiological mechanisms of exercises. The findings will enhance our understanding of the mechanisms underlying mind-body exercise and facilitate the development of new pain management approaches.

Outcome Measures
Primary Outcome Measures
- Change on functional connectivity of the bilateral M1. [Baseline, post-treatment (12 weeks)]
Resting state connections between the primary motor area (M1) and other brain regions
Secondary Outcome Measures
- Change on cerebral blood flow [Baseline, post-treatment (12 weeks)]
Cerebral blood flow will be measured using arterial spin labeling (ASL)
- Change on M1 corticospinal excitability and cortico-cortical excitability [Baseline, post-treatment (12 weeks)]
M1 corticospinal excitability will be measured using motor threshold, motor evoked potential, short-interval intracortical inhibition (SICI) and intracortical facilitation (ICF).
- Change on brain gray matter volume [Baseline, post-treatment (12 weeks)]
Voxel-based morphometry (VBM) analysis will be performed to investigate gray matter volume changes.
- Change on Knee Injury and Osteoarthritis Outcome Score (KOOS) [Baseline, post-treatment (12 weeks), follow-up (24 weeks)]
The KOOS is a 35-item self-administered survey of pain and function in knee OA patients.
- Change on Patient-Reported Outcomes Measurement Information System (PROMIS)-29 [Baseline, post-treatment (12 weeks), follow-up (24 weeks)]
We will use PROMIS-29 to assess pain, function, depression, anxiety, and sleep in the past 7 days.
- change on Beck's Depression Inventory (BDI-II) [Baseline, post-treatment (12 weeks), follow-up (24 weeks)]
BDI-II is designed for individuals aged 13 and over and is composed of items relating to symptoms of depression.
- Change on Pain Catastrophizing Scale (PCS) [Baseline, post-treatment (12 weeks), follow-up (24 weeks)]
PCS is a 15-item questionnaire used to characterize an individual's tendency to magnify the threat value of a pain experience and to feel helpless in the presence of pain.
- Change on Quantitative Sensory Testing (QST) [Baseline, post-treatment (12 weeks), follow-up (24 weeks)]
Pressure pain thresholds will be assessed 3 times using a Somedic digital pressure algometer. Contact heat stimuli will be delivered using a PATHWAY CHEPS (Contact Heat-Evoked Potential Stimulator, Medoc Advanced Medical Systems).
- Change on 6-Minute Walk Test [Baseline, post-treatment (12 weeks), follow-up (24 weeks)]
The 6-Minute Walk Test is a self-paced endurance test that assesses walking ability and endurance and includes standardized encouragement that increase tolerability in elders and those with physical impairment.
