HILT for Meralgia Paresthetica

Participants will undergo HILT treatment using a diode laser device (wavelength: 1064 nm; power: 12 W; peak power: 50 W; energy density: 600 J/cm²; spot size: 1 cm²; pulse duration: 200 μs; pulse frequency: 10 Hz) applied in continuous mode. The laser probe will make contact with the skin over the LFCN entrapment site at three specific points: (a) the inguinal ligament, (b) the point of maximum tenderness along the nerve pathway, and (c) the mid-point between the ASIS and the lateral border of the patella. Each point will be treated for 1 minute and 40 seconds, totaling a 5-minute session. Participants will undergo 12 sessions in total, with three sessions per week for four weeks.

Participants will undergo sham HILT treatment using an identical laser device with no active laser output, following the same treatment protocol as the HILT group. The laser probe will make contact with the skin over the LFCN entrapment site at the same three specific points as the HILT group. Each point will be treated for 1 minute and 40 seconds, totaling a 5-minute session. Participants will undergo 12 sessions in total, with three sessions per week for four weeks.
