Outcome Measures

Primary Outcomes (1)

  • Pain ratings (Numeric Rating Scale)

    The primary efficacy outcomes are the effects of the rTMS modalities on pain app ratings.

    Pain ratings immediately after each rTMS modality and effects after the end of stimulation round (1 week).

Secondary Outcomes (4)

  • Pain trajectories

    1 to 12 weeks (end of the study)

  • Brain biomarkers and psychological indicators of rTMS effects and pain relief

    1 to 12 weeks (end of the study)

  • Adverse events

    1 to 12 weeks (end of the study)

  • Global impression of change

    1 to 12 weeks - after each rTMS round.

Study Arms (3)

Stimulation Modality 1

EXPERIMENTAL

Repetitive TMS will be applied at 100% resting motor threshold intensity to a region of interest located in the parietal cortex, that will be determined based on its connectivity with the hippocampus.

Device: Transcranial Magnetic Stimulation

Stimulation Modality 2

SHAM COMPARATOR

Parameters will be identical to the modality 1, except that the coil will be flipped over.

Device: Transcranial Magnetic Stimulation

Stimulation Modality 3

ACTIVE COMPARATOR

The stimulation will be delivered over the motor cortex contralateral to the predominant painful region, i.e., right motor cortex stimulation if left knee pain. The stimulation intensity will be set at 80% of the resting motor threshold.

Device: Transcranial Magnetic Stimulation

Interventions

The brain stimulation can be delivery using different devices; in this project a MagPro X100 stimulator connected to a MagPro Cool-B65 liquid-cooled butterfly coil (MagVenture A/S, Farum, Denmark) will be used. Resting motor threshold (M1-rTMS) will be determined during the visit 1 or visit 2 and used along all visits. The rTMS pulse sequences and intensities used are all within the published safety guidelines
