Abstract:

Radiofrequency (RF) currents are used as a treatment modality for chronic pain management. This is achieved by blocking sensory nerves’ ability to propagate pain signals to the brain where they are perceived. The current can be applied continually (CRF) or in a pulsed manner (PRF). PRF mode has recently gained popularity due to minimal patient discomfort with promising results. In this thesis, it was (1) shown that in 60% of earthworms treated with bipolar PRF at 70V, 20ms pulse width with pulse repetition rate of 2Hz for 120 seconds experienced a block in action potential propagation, (2) computer simulations of the treatment were created to examine the electrical field and heating patterns and (3) after determining a threshold thermal dose for nerve damage, it was shown that (4) a C6 medial branch nerve PRF treatment is not strong enough to cause thermal damage.
