Alterations in this muscle may contribute to the onset of low back pain by modifying spinal biomechanics, particularly through increased lumbar lordosis and greater mechanical overload in the lumbar region.\n\nLatent myofascial trigger points are asymptomatic but can lead to muscle shortening and weakness. They are characterized by local tenderness and may provoke a localized muscular response known as a local twitch response.\n\nThe aim of this randomized experimental study was to evaluate the immediate effect of ischemic compression applied to the trigger point of the psoas muscle on pain perception and lumbar range of motion.\n\nResearchers will compare a group with a placebo technique to see if the release of the psoas muscle produces effects in this condition.\n\nThe variables analyzed in this study included low back pain, assessed using the Numeric Pain Rating Scale (NPRS); lateral lumbar flexion (right and left), measured using a tape measure (distance from the third finger to the floor); and lumbar flexion range of motion, assessed using the Schober test.",[58],"Low Back Pain","NOT_YET_RECRUITING","2025-09-15",{"date":62,"type":63},"2025-09-16","ACTUAL",{"date":65,"type":52},"2026-04",{"date":67,"type":52},"2026-09",{"name":5,"class":6}]
