Brief Summary

Objectives: To investigate the efficacy of omega-3 polyunsaturated fatty acids (PUFA) on patients with chronic nonspecific low back pain (NLBP). Methods and Materials: Twenty-nine patients with chronic NLBP were randomly divided into experimental and control groups. For 8 weeks, participants in the experimental group received omega-3 PUFA at 3000 mg/day plus physical therapy, while those in the control group received placebo plus physical therapy. The visual analog pain scale, pressure algometer, Biering-Sorenson test, Roland-Morris Low Back Pain and Disability Questionnaire (RMQ), and occupational burnout inventory (OBI) were used in assessments at baseline (T0) and after 4 (T1) and 8 weeks (T2). Serum erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (hs-CRP) were checked at baseline and T2.

Experimental group

EXPERIMENTAL

Participants in the experimental group will take fish oil (five 1000mg fish oil soft capsules per day, each capsule containing 350mg EPA and 250mg DHA) and receive physical modality treatment (hotpacking 15min and transcutaneous electrical nerve stimulation (TENS) 15min, three times a week) for 8 weeks

Dietary Supplement: Fish oilProcedure: HotpackingProcedure: Transcutaneous electrical nerve stimulation (TENS)

Control group

PLACEBO COMPARATOR

Participants in the control group will take placebo (five 1000mg sunflower oil soft capsules per day) and receive physical modality treatment (hotpacking 15min and transcutaneous electrical nerve stimulation (TENS) 15min, three times a week) for 8 weeks
