TITLE

Effectiveness of Low-Level Laser Therapy in Patients with Discogenic Lumbar Radiculopathy: A Double-Blind Randomized Controlled Trial

110 Patients, 18 Sessions

SOURCE

This double-blind randomised controlled trial, conducted in Pakistan, tested whether adding low-level laser therapy to standard physical therapy improves outcomes for people with acute low back pain and one-sided leg pain caused by a disc herniation, using 110 patients.

What was studied?

110 patients were split evenly between physical therapy alone and physical therapy plus laser therapy, applied to four points over 18 sessions across 6 to 8 weeks, measuring changes in leg pain and overall disability.

What did they find?

The group who received laser therapy alongside physical therapy had substantially better outcomes than physical therapy alone, with a mean difference of 2.52 in leg pain reduction and 4.10 in disability improvement, both favouring the combined treatment.

Why it matters

This is one of the specific trials behind a broader systematic review, reinforcing the same pattern: laser therapy appears most useful as an add-on to standard physical therapy, not as a replacement for it.

Why we included it

It shows how individual trials feed into wider reviews: this study's specific results align with the broader pattern seen across the evidence, strengthening confidence rather than standing alone as an isolated result.
