Trial Outcomes & Findings for Repetitive Transcranial Magnetic Stimulation for Musculoskeletal Pain in Patients With Parkinson's Disease (NCT NCT05537597)

NCT ID: NCT05537597

Last Updated: 2026-02-17

Results Overview

Modified King's PD Pain Scale (MKPPS),the modified version which is more suitable for Chinese people, combined with Ford's pain subtypes basing on the original. It covers five main domains, including 16 items, each item scored by severity (0-3) multiplied by frequency (0-4), resulting in a total possible score range from 0 to 192. Higher scores indicate greater symptom severities and more serious influence.

Measure
M1-rTMS Group
active M1-rTMS: Magnetic stimulation will be carried out using a MagPro X100 machine with a MCF-B70 figure-of-eight coil (Magventure, Farum). All rTMS sessions will be assisted by a neuronavigation system (TMS Navigator,Localite GmbH), maintaining the M1 target and the orientation of coil stable during stimulation sessions. The M1 target was defined as the "hand knob" region, which corresponds to the motor cortical representation of the hand, regardless of the location of pain. Stimulation paradigm consists of 20 trains of pulses with an intra-train frequency of 20 Hz, resulting in 2000 pulses for a total duration of 20 minutes. The stimulation intensity will be 80% of RMT, defined as the lowest stimulation intensity necessary to induce a visible muscle twitch of the hand contralateral to the stimulated hemisphere. Participants will receive 7 sessions of treatment once a day in the same time continuously for 7 days, and keep antiparkinsonism drugs unchanged throughout the whole study.
Sham-rTMS Group
sham rTMS: The sham protocol was similar to the rTMS protocol. Sham stimulations will be performed with a MCF-P-B65 figure-of-eight coil (Magventure) to M1, assisted by a neuronavigation system. The following stimulation parameters will be used: stimulus frequency 20 Hz; stimulus intensity 80 % of RMT; total stimulation pulses 2,000; total stimulation time 20 min. Participants will receive 7 sessions of treatment once a day in the same time continuously for 7 days, and keep antiparkinsonism drugs unchanged throughout the whole study.

PRIMARY outcome

Timeframe: before the first rTMS session (day 1), after rTMS therapy (day8、1month、2months)

KING'S PD Pain Scale (KPPS) Domain 1 focused on musculoskeletal pain, covering one item, which was scored by multiplying severity (from 0 \[no pain\] to 3 \[very severe pain\]) by frequency (from 0 \[never\] to 4 \[all the time\]), yielding sub-scores between 0 and 12. Higher scores indicate greater symptom severity.

SECONDARY outcome

Timeframe: before the first rTMS session (day 1), after rTMS therapy (day8)

Population: 55 patients participated in the EEG assessment before and after treatment. However, only 30 in M1-rTMS and 17 in sham-rTMS were retained for the final analysis, as 8 patients' EEG signals were faulty.

For each EEG epoch, we computed the fast Fourier transform (FFT) algorithm to convert to frequency domain. The power values in following five frequency bands were obtained: delta (1-4Hz), theta (4-8Hz), alpha(8-13Hz), beta(13-30Hz), gamma(30-80Hz).

M1-rTMS Group
n=40 Participants
active M1-rTMS: Magnetic stimulation will be carried out using a MagPro X100 machine with a MCF-B70 figure-of-eight coil (Magventure, Farum). All rTMS sessions will be assisted by a neuronavigation system (TMS Navigator,Localite GmbH), maintaining the M1 target and the orientation of coil stable during stimulation sessions. The M1 target was defined as the "hand knob" region, which corresponds to the motor cortical representation of the hand, regardless of the location of pain. Stimulation paradigm consists of 20 trains of pulses with an intra-train frequency of 20 Hz, resulting in 2000 pulses for a total duration of 20 minutes. The stimulation intensity will be 80% of RMT, defined as the lowest stimulation intensity necessary to induce a visible muscle twitch of the hand contralateral to the stimulated hemisphere. Participants will receive 7 sessions of treatment once a day in the same time continuously for 7 days, and keep antiparkinsonism drugs unchanged throughout the whole study.
Sham-rTMS Group
n=22 Participants
sham rTMS: The sham protocol was similar to the rTMS protocol. Sham stimulations will be performed with a MCF-P-B65 figure-of-eight coil (Magventure) to M1, assisted by a neuronavigation system. The following stimulation parameters will be used: stimulus frequency 20 Hz; stimulus intensity 80 % of RMT; total stimulation pulses 2,000; total stimulation time 20 min. Participants will receive 7 sessions of treatment once a day in the same time continuously for 7 days, and keep antiparkinsonism drugs unchanged throughout the whole study.
