The study evaluated the effectiveness of TENS and LLLT therapies on sciatic Valleix points to alleviate sciatica in 164 patients with chronic lumbar radiculopathy due to herniated discs.
Patients were divided into three groups to receive different treatments (LLLT, TENS, or sham LLLT) over 15 sessions, and outcomes were measured at multiple intervals.
Results showed that both treatments improved symptoms, but LLLT was significantly more effective than TENS in reducing leg pain and neuropathic pain, with lasting effects noted at the three-month follow-up.
