Study Stopped
Preliminary data in chronic back pain patients showed no benefits of the treatment; we did not further pursue the same treatment in osteoarthritis patients.

Brief Summary
In this study the investigators aim to examine the effects of Transcranial Magnetic Stimulation (TMS) on hippocampal network connectivity and pain levels in individuals with pain due to knee osteoarthritis.

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
EXPERIMENTALRepetitive 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.
Stimulation Modality 2
SHAM COMPARATORParameters will be identical to the modality 1, except that the coil will be flipped over.
Stimulation Modality 3
ACTIVE COMPARATORThe 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.
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
