Background: Low back pain (LBP) is a common musculoskeletal problem in recent days, and 85% of LBP is NSLBP. Studies have shown that psoas syndrome can be the cause of pain in lumbosacral region in a clinical scenario.
Aims and Objectives: To find out the immediate effect of contract-relax antagonist-contract (CRAC) method on iliopsoas muscle and hamstring muscle stretching on chronic NSLBP.
Materials and Methods: Totally 30 subjects from both genders were selected based on inclusion criteria were aged from 20 to 30 years, chronic NSLBP of more than 3 months, iliopsoas muscle tightness at least one side (positive from modified Thomas test). Pain intensity at least 3/10 on a 10-cm visual analog scale (VAS). Hamstring tightness with a minimum of −6 cm (male), −10 cm (females) done by sit and reach test. CRAC technique and hamstring stretching were administered.
Results: Pre- and post-test values of all the outcomes measure are 0.000, there is a significant result exist between the VAS scale, hamstring and iliopsoas flexibility, before and after the interventions (P < 0.05).
Conclusion: CRAC stretching technique combined with hamstring stretching can reduce back pain.
Key words: Chronic Non-specific Low Back Pain; Contract-relax Antagonist-contract Method; Iliopsoas; Hamstring Flexibility
