Effect of Quadratus Lumborum Muscle Energy Technique in Sacroilliac Joint Dysfunction.

Objective: To determine the effectivness of muscle energy technique versus strain counter strain techniques on trigger points of quadratus lumborum among patients with low back pain. Methodology: A quasi-experimental trial was conducted on 40 patients who had low back pain due to trigger points in Sialkot medical complex hospital, Sialkot. The participants were divided into group A (MET) and group B (SCS). Group A was treated with muscle energy techniques and moist heat therapy, while Group B was treated with strain counter strain technique and moist heat therapy for two weeks. Numeric pain rating scale and Modified Oswestry Disability Questionnaire were used. Data was analyzed on SPSS 21. Results: The mean score of the Oswestry Disability Index (ODI) was 53.10±7.35 and 56.60 ± 7.89 at the start of treatment in group A (MET) and group B (SCS), respectively. The final ODI score for group A (MET) and group B (SCS) was 22.25± 5.87 and 37.70± 7.87, respectively. The mean value of pain intensity on the Numerical Pain Rating Scale (NPRS) was 7.30±1.25 vs. 7.85±1.26 at the start of treatment in Group A (MET) and Group B (SCS), respectively. The post-treatment NPRS score was 3.20 ±1.16 vs. 4.55±1.20 for Group A (MET) and Group B (SCS), respectively. Conclusion: According to the findings of this study, both METS and SCS significantly improved pain and functional disability in patients with low back pain caused by trigger points in the quadratus lumborum. However, in terms of mean difference, METS are more effective than SCS. Keywords: Strain counter strain, METS, Trigger points, Quadratus lumborum, Low back pain

Introduction: Breast cancer is a major cause of morbidity and mortality, leading to functional deficiencies in ventilation, muscle performance, balance and posture.Objective: To describe the effects of the muscle energy technique (MET) for quadratus lumborum on maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) in patients with stage I and II breast cancer.Materials and methods: Quasi-experimental study with a pretest-posttest design conducted in 10 patients treated at a highly specialized healthcare center in Bogotá. Physical therapy assessment and three physiotherapy sessions with the MET to measure MIP and MEP were carried out before and after the intervention using a respiratory pressure meter.Results: The average MIP was 41% of the reference value at the beginning of the intervention, which increased to 69% at the end of the sessions. On the other hand, the initial average MEP was 33%, while the post-intervention average MEP was 51%. The average change rate for MIP was 68% and 57% for MEP. The Wilcoxon signed-rank test was performed, achieving a statistically significant difference (z=-2.807, p=0.005).Conclusion: Applying the MET on the quadratus lumborum muscle improves its performance and increases respiratory muscle strength.
