Psoas Major Muscle Intervention on Chronic Lumbar Pain in Cleaning Professionals.
Sponsor: Escola Superior de Tecnologia da Saúde do Porto
Summary
The goal of this randomized controlled trial is to determine the effect of a psoas major muscle intervention on non-specific and chronic lumbar pain in cleaning professionals. It is expected that this intervention will reduce the severity and frequency of symptoms. This study aims to evaluate the effect of psoas major stretching techniques. To collect data, participants will rate their pain intensity on a numeric pain scale at rest and during maximal lumbar flexion. Secondary variables include lumbar flexion range of motion (ROM), assessed by the Schöber test, and hip ROM, which will be measured before and after the intervention using a digital goniometer.

Interventions
Psoas stretching technique
The patient is positioned supine at the edge of the table. The investigator places their hands on both of the participant's knees, applying gentle downward pressure on the ipsilateral knee to stretch the psoas major muscle. This stretch is held for 30 seconds and performed bilaterally (once on each side) to the experimental group.
Placebo
Patient is positioned supine at the edge of the table. The investigator places one hand on the participant's ipsilateral knee without applying any pressure or force, and the other hand on the contralateral knee for stabilization. This position is maintained for 30 seconds to match the duration of the experimental intervention. The technique was performed bilaterally (once on each side) to the control group.
