What the trial is, and whether it could suit you
The goal of this clinical trial is to explore the effects of accelerated intermittent Theta Burst Stimulation (iTBS) on pain relief and cognitive function in older adults with chronic musculoskeletal pain. It will also utilize magnetic resonance imaging to illustrate the neurophysiological mechanisms underlying the role of iTBS in improving various outcome indicators in this population.
The main questions it aims to answer are:
1. Is left dorsolateral prefrontal cortex stimulation using accelerated iTBS effective for older adults with chronic musculoskeletal pain?
2. What are the neurophysiological mechanisms underlying the role of iTBS in improving various outcome indicators in older adults with chronic musculoskeletal pain?
Participants will:
1. Receive 1,200 stimuli during a single-session iTBS, totaling 14 days.
2. Undergo MRI scanning before, immediately after treatment, cogniti
