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.
Background: Low back pain is a widespread pain condition in the working population. Anticipatory postural adjustment of the transverses abdominis muscle has received particular interest for the research of postural control in low back pain. The relationship between tibialis anterior anticipatory postural adjustment and the pain reported in low back during prolong standing. Aims and Objectives: To find out the effect of core stabilization program on core muscle endurance and functions in staff nurses. Materials and Methods: Study design was quasi-experimental study, done with a sample size of 18 staff nurses, at SRM Ladies Medical Hostel, SRM Medical College Hospital and Research Centre, SRM University, Kattankulathur, India. Subjects were selected according to inclusion and exclusion criteria, and informed consent was taken, and intervened with a core stabilization exercise program for about 8 weeks; endurance and functional test were measured before and after the intervention. Paired t-test was done to find out the difference before and after the intervention. Results: Shows there is a significant difference (P < 0.05) in endurance test (flexor, extensor, and horizontal side support) and there is no significant difference (P > 0.05) in functional test (single leg distance hop test, timed leg hop test, and squat test). Conclusions: 8 weeks core stabilization training showed improvement of core endurance, but not on functions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
