PENGARUH STIMULASI MAGNETIK REPETITIF PERIFER TERHADAP KONTROL MOTOR LUMBOPELVIS DAN KEMAMPUAN FUNGSIONAL PADA NYERI PUNGGUNG BAWAH MEKANIK KRONIK
Abstract
Introduction : Low back pain (LBP) is the most common musculoskeletal problem globally. Janitor is a job that requires strong physical abilities so it is vulnerable to the occurrence of LBP. In recent years, lumbopelvic stability exercises, especially motor control exercises, have received more attention in the management of chronic LBP because several studies have shown that in chronic LBP there is a decrease or delay in activation of the core muscles, especially the multifidus and transversus abdominis muscles. This study aims to analyze the effect of SMRP on lumbopelvic motor control and functional ability in chronic mechanical LBP. Method: This research is an experimental study with one group pre test – post test design which was conducted at the Medical Rehabilitation Installation of Prof. RSUP. Dr. R. D. Kandou Manado from September to November 2023. There were 17 janitor subjects with chronic mechanical low back pain who participated in the study for 10 therapy sessions. The treatment given was repetitive peripheral magnetic stimulation (RPMS) therapy with strengthening mode. The ability of lumbopelvic motor control was assessed by active straight leg test (ASLR) using Chattanoga pressure biofeedback before and after 10 sessions of therapy. Result: There is a very significant difference between the median value before and after being given SMRP (Z = -3.688 with a p value <0.001) and a very significant difference between the average Oswestry Disability Index (ODI) value before and after being given SMRP (t = 10.517 with a p value <0.001). Conclusion : SMRP therapy with strengthening mode can improve lumbopelvic motor control in chronic mechanical LBP patients and improve the functional abilities of chronic mechanical LBP patients.
