EMpulse for SCIATICA The study cited below illustrates that sciatica is highly responsive to PEMF.  EXPERIENCE We have treated hundreds of sciatic pain problems with good success. This is a situation where one is more likely to relieve the pain than to cure the problem, although that sometimes happens as well. TREATMENT Sciatica is a midline problem even though it might be felt elsewhere. Move EMpulse up and down the midline for 3-4” and then once or so out toward the pain on a forty five degree slope. Treat 30-60 minutes for 1-3 times per day for four days then place it over the area that showed best results and leave EMpulse there for as long as you like.   EMpulse - the most advanced Pulsed Electromagnetic Field device available today. EMpulse circuit is FDA certified for relief of joint and muscle pain.

Objectives: To assess the influence of low frequency pulsed electromagnetic fields on peripheral nerve regeneration.

Methods and results: Six male Swiss mice (Mus musculus), weighing 35 to 45 g, were submitted to an unilateral sciatic nerve crush for 30 seconds, with a non-serrated needle-holder. The animals were randomly assigned to a control or experimental group. All of them were submitted 5 times a week, to light anesthesia wiht halotane. The experimental group also was was also exposed to a 72 Hz pulsed electromagnetic field on injury site, for 30 minutes. Function was assessed weekly by Static Sciatic Index for mice (SSIm). After three weeks, mice were perfused transcardiacly and sciatic nerves from either sides processed for optic and electron microscopy. Results from functional tests showed a better but not statisticaly significant recovery of function on the experimental group. On the second week post-lesion, where differences were more marked, the SSIm was -49.78±17.56 for the experimental group and -64,27±17.13 for the control group. Based on these values we obtained a size sample of 44 animals in order to show significant differences among the groups, with the power of the study being 80% and alfa of 0.05. Maybe morphological analysis shows a different pattern, requiring less animals.

Conclusions: This study presents, as a partial conclusion, that low frequency pulsed electromagnetic fields has the potential to enhance peripheral nerve regeneration assessed by functional tests in a mouse model of sciatic crush lesion.

Previous studies showed that exposure to pulsed electromagnetic fields (PEMF) produced a 22% increase in the axonal regeneration rate during the first 6 days after crush injury in the rat sciatic nerve. We used the same injury model to assess the effect on functional recovery. The animals were treated with whole body exposure to PEMF (0.3 mT, repetition rate 2 Hz) for 4 h/day during Days 1-5 while held in plastic restrainers. Functional recovery was serially assessed up to Postinjury Day 43 using recently described video imaging of the 1-5 toe spread and the gait-stance duration. Footprint analysis was also used with calculation of a sciatic function index. Those animals treated with PEMF had improved functional recovery, as compared to sham controls, using the tests for video 1-5 toe spread and gait-stance duration (P = 0.001 and P = 0.081, respectively). This effect was found throughout the 43-day recovery period. No effect was found using the sciatic function index. This study confirms that functional recovery after nerve crush lesion is accelerated by PEMF and has broad implications for the clinical use of these fields in the management of nerve injuries.
