Short-term effects of high-intensity laser therapy versus ultrasound therapy in the treatment of low back pain: a randomized controlled trial

30 consecutive patients with clinically verified sub-acute or chronic low back pain were randomized to receive 15 treatments (5 days a week for 3 weeks) of either ultrasound or laser therapy. Ultrasound was administered at 1MHz for 10 minutes.  2600 J of laser therapy was administered to the same treatment area over 10 minutes. The laser therapy group “showed a statistically significant reduction of Visual Analog Scale pain and Oswestry Low Back Pain Disability Questionnaire scores with respect to Ultrasound at the end of treatment (P<0.005)”
