NCT06709963

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:

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

Outcome Measures

Primary Outcomes (3)

  • The recruitment rate, retention rate (completion rate), non-completion reasons, drop-out rate

    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.

    Immediately after the intervention

  • ITBS acceptability questionnaire

    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.

    Immediately after the intervention

  • Pain intensity assessment

    The 11-point numerical rating scale, ranged from 0 to 10, higher scores indicate higher pain intensity.

    Baseline, immediately after the intervention, five-month follow-up at one-month,three-month,six-month follow-up timepoints.

Secondary Outcomes (15)

  • Depression, anxiety, and stress test

    Baseline

  • Disability evaluation

    Baseline, immediately after the intervention, five-month follow-up at one-month,three-month,six-month follow-up timepoints.

  • Pain catastrophizing assessment

    Baseline, immediately after the intervention, five-month follow-up at one-month,three-month,six-month follow-up timepoints.

  • Pain drawing test

    Baseline

  • Frailty status assessment

    Baseline, immediately after the intervention, one-month follow-up timepoint.

  • +10 more secondary outcomes

Interventions

ITBSDEVICE

We will use a coil called Cool-6000 A/P to conduct real and sham control. This coil will be placed on the scalp of older adults. The iTBS protocol will begin with a 2-s burst train (totally 30 pulses), repeating every 10 s. Each burst train will consist of 10 triplet pulses with an inter-burst interval of 0.16 s, thus the triplets fire at a rate of 5 Hz. ITBS parameters will include three continuous pulses at 50 Hz repeated at 5 Hz (2s on, 8s off) for a total of 600 pulses. We will administer two rounds of iTBS per treatment day, with a 15-minute interval between the two sessions. In total, each participant will receive 1,200 stimuli during a single-session iTBS, totaling for 14 days. Each treatment session will last for about 30 minutes. Intermittent θ-burst stimulation intensity will be set at 70% of the resting motor threshold.
