Purpose: to trace the effectiveness of both pulsed electromagnetic field therapy (PEMFT) and polarized light therapy (BLT) in the treatment of sciatic nerve post-herpetic neuralgia. Methods of evaluation: The evaluation is done via the estimation of the consumption of carbamazepine (CMI) and the measurement of the serum cortisol level (SCL). Methods: Participants in the current academic work were 40 cases with post-herpetic neuralgia of the sciatic nerve (30 men and 10 women), ranging in age from 25 to 40. They were randomly sub-categorized into two study domains; 2 equal groups (A) and (B). Twenty cases from Group (A) underwent BLT in addition to conventional physical therapy. Twenty cases from Group (B) got PEMFT in addition to standard physical therapy care. For a total treatment length of three months, BLT and PEMFT were adopted successfully. Each session lasted 30 minutes and was performed unilaterally over the afflicted side along the sciatic nerve pathway from up to down, while the case is having the prone position. In groups (A) and (B), the BLT and JAMAVA apparatuses, respectively, were administered paravertebrally at the l5-S1 (erector-spinae motor point) level for ten minutes. The painful buttock and upper motor point of the gluteus maximus were then treated with the BLT and JAMAVA apparatus for an additional 10 minutes. Then, for 5 minutes, BLT and JAMAVA devices were applied at the junction of the greater trochanter and ischial tuberosity at the level of the buttock and posterior upper thigh. Finally, they were administered for a further five minutes right above the popliteal crease.
