Comparison of Hip Extensor Strength and Lumbopelvic Stability in persons with Non Specific low back pain vs normal healthy persons: An Observational Study

Abstract

Background: Persons with LBP (LBP) avoid painful trunk movements. Also hip spine interaction gets disturbed in LBP. Conventional treatment has emphasized on transversus abdominis and multifidus. But hip extensors have received very little attention. Objective: To assess lumbopelvic stability and hip extensor strength in persons with non-specific LBP & normal healthy individuals. Study Design: Cross-Sectional Observational Study Study Setting: Pain Clinics Participants: 50 healthy individuals and 50 with Non-Specific LBP Interventions: It was an Observational Study. Ethical Committee approval was taken. 110 persons were divided into 2 groups: Group A (control group) and Group B (LBP Group). Training of Abdominal Draw-In Maneuver was given using pressure biofeedback for 3 days and assessed using Sahrmann’s Test. Isometric hip extensor strength was assessed using Isokinetic dynamometer. Data was analysed using Wilcoxian Signed-Rank Test and Mann-Whitney U Test. Outcome Measures: Sahrmann’s Lumbopelvic Stability Test and Hip Extensor Peak Torque Results: Lumbopelvic stability of LBP group was significantly lesser than control group. Between group comparison of dominant as well as non-dominant limb torque did not show any significant difference. Conclusion: Lumbopelvic stability was significantly lesser in persons with non-specific LBP group. In across group comparison, hip extensors strength did not show significant difference in dominant as well as non-dominant limb
