Description of intervention(s) / exposure
Double Blind Randomised Control Trial of a single Active (6x two-minute 10ms 5pps 80V in one treatment session) and a single Inactive (6x two-minute 0V in one treatment session) Transcutaneous Pulse Radiofrequency Treatment For Shoulder Pain in patients awaiting non-stabilisation shoulder surgery that takes about 15 minutes to perform. There is a gap of about 30 seconds between the 6 treatments which is the time to reposition the two topical self-adhesive electrodes. Transcutaneous PRF is a non-invasive, non-destructive, needle-free treatment that applies a precisely targeted pulsing electrical field around the target nerve that ‘stuns’ rather than destroys the nerve and making the nerve incapable of transmitting pain signals. Although it is not known how transcutaneous PRF works, it is thought to induce long lasting biochemical changes in the target spinal nerves without disrupting sensation or motor function. Treatment can be repeated if there was a good response to the first transcutaneous PRF.
