Overview
Brief Summary
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:
- Is left dorsolateral prefrontal cortex stimulation using accelerated iTBS effective for older adults with chronic musculoskeletal pain?
- What are the neurophysiological mechanisms underlying the role of iTBS in improving various outcome indicators in older adults with chronic musculoskeletal pain?
Participants will:
- Receive 1,200 stimuli during a single-session iTBS, totaling 14 days.
- Undergo MRI scanning before, immediately after treatment, cognitive and pain-related tests before, immediately after treatment, and during follow-up.

- •an average pain intensity of ≥ 5 out of 10 on an 11-point numerical rating scale in the last 7 days, where 0 means "no pain" and 10 means "worst pain imaginable"

Outcomes
Primary Outcomes
ITBS acceptability questionnaire
Time Frame: Immediately after the intervention
ITBS acceptability questionnaire has ten items of positive acceptability, ranged from 10 to 50, and it also has five items of negative acceptability, ranged from 5 to 25. The iTBS acceptability questionnaire has a total score ranging from 15 to 75.
The recruitment rate, retention rate (completion rate), non-completion reasons, drop-out rate
Time Frame: Immediately after the intervention
The recruitment rate, retention rate (completion rate), non-completion reasons, drop-out rate will be evaluated as our primary outcomes, because of the feasibility of the study.
Pain intensity assessment
Time Frame: Baseline, immediately after the intervention, five-month follow-up at one-month,three-month,six-month follow-up timepoints.
The 11-point numerical rating scale, ranged from 0 to 10, higher scores indicate higher pain intensity.
Secondary Outcomes
- Disability evaluation(Baseline, immediately after the intervention, five-month follow-up at one-month,three-month,six-month follow-up timepoints.)

- Cognitive inhibition test inside magnetic resonance imaging scanning(Baseline, immediately after the intervention.)
- Cognitive flexibility test outside magnetic resonance imaging scanning(Baseline, immediately after the intervention, one-month follow-up timepoint.)
- Depression, anxiety, and stress test(Baseline)
- Physical activity assessment(Baseline, immediately after the intervention, one-month follow-up timepoint.)
- Sleep quality assessment(Baseline, immediately after the intervention, one-month follow-up timepoint.)
- Cognitive flexibility test inside magnetic resonance imaging scanning(Baseline, immediately after the intervention.)
- Perseveration and abstract reasoning test outside magnetic resonance imaging scanning(Baseline, immediately after the intervention, one-month follow-up timepoint.)
