Summary
Brief summary (as posted)
The purpose of this study is to assess the efficacy of rTMS over primary motor cortex in patients suffering from malignant visceral pain. Thirty four patients were included in the study. They are divided randomly into 2 groups using closed envelop as real rTMS group and sham group. Real rTMS over the hand area of motor cortex (20 Hz, 10 trains with inter train interval 30 second with total pulses 2000, intensity 80% of motor threshold) every day for ten consecutive days (5 days/week) and the coil elevated and angled away from the head as sham stimulation. Patients were evaluated by verbal descriptor scale (VDS), visual analog scale (VAS), and Hamilton rating scale for depression (HAM-D) at the baseline, after 1st, 5th, 10th session, 15 day and 1 month after end of sessions. Serum human dynorphin (Dyn) level was measured at baseline, 5th and 10th session.

- SHAM_COMPARATOR
- label
- Sham rTMS
- description
- Sham-rTMS was applied using the same parameters but with the coil elevated and angled away from the head to reproduce some of subjective sensation of rTMS.
- interventionNames
- Procedure: Sham rTMS (same parameters but with coil elevated and angled away from the head) every day for 10 consecutive days (5 days/week).
- type
- ACTIVE_COMPARATOR
- label
- Real rTMS
- description
- The active group recieved real-rTMS over the motor cortical area corresponding to the hand of painful side. Each train consist of 2000 pulses at 20 Hz and 80% RMT (total duration 10s). The treatment was repeated every day for 5 consecutive days in week for two weeks (the total number of sessions had be given was 10 sessions).
