Comparative Effect of Diaphragmatic Training in Patients With Chronic Non-specific Low Back Pain

Summary

Background: The diaphragm muscle is a respiratory muscle with postural function. Patients with chronic LBP (CLBP) are more susceptible to diaphragm fatigue than healthy people and, therefore, can likely benefit from exercises designed to improve strength/endurance in this muscle. Studying the results of diaphragmatic training versus myofascial release was a strategy for determining which of them was the most effective in improving pain, flexibility and disability in the patients with chronic non- specific low back pain.

Objective: The objective of the study will be to compare the effect of Diaphragm training and myofascial release back pain patients.

Methods: A randomized clinical trial will be conducted on 44 patients aged 20-45 years. The patients will be randomized using lottery method. Group A will underwent diaphragmatic training with four positions with hot-pack and therapeutic ultrasound as baseline treatment NPRS will be used to measure the intensity of pain, ODI for the measurement of disability and Schober's test for lumbar flexibility before and after the completion of treatment sessions. Group B will receive myofascial release of diaphragm for 15 minutes with two sets of repetition of 10 breaths with a one-minute interval between them. Total duration will be 4 weeks.

Diaphragm Training

The diaphragm serves dual roles in respiration and postural control, yet its contribution is often overlooked in core stability exercise (CSE) programs for low back pain (LBP) rehabilitation. Abdominal hollowing, or the 'tummy tuck,' targets TrA and lumbar multifidus. Diaphragmatic breathing (DB) increases intra-abdominal pressure, contributing to lumbar stability. The intervention included four progressive weeks: Week 1-Supine and Crocodile breathing; Week 2-Supine and Crocodile with TheraBand; Week 3-Seated and 90/90/90 breathing; Week 4-Seated and 90/90/90 with TheraBand. Supine emphasized diaphragmatic expansion with resistance at the thoracolumbar junction; Crocodile focused on lateral rib expansion; Seated required upright posture with rib control; 90/90/90 integrated deep breathing with resisted stabilization. This study evaluates DB combined with CSE on pain, disability, muscle activity, and sleep quality in chronic LBP.

Myofascial Release Technique

The myofascial release technique for the diaphragm was performed with the participant lying supine and limbs relaxed. The therapist, positioned at the head, placed the pisiform, hypothenar, and last three fingers bilaterally under the seventh to tenth rib costal cartilages, forearms aligned toward the shoulders. During inspiration, gentle traction was applied cephalad and slightly laterally, accompanying rib elevation. On exhalation, pressure was directed inward along the costal margin to maintain resistance. With each breath, traction was gradually deepened to improve release. The maneuver consisted of two sets of 10 deep breaths with a 1-minute rest between sets. Figure 1 illustrates the manual diaphragm release technique (source: author's photo). This method, adapted from Rocha et al. (2015), emphasizes progressive traction and controlled resistance to facilitate diaphragmatic mobility and rib cage expansion.
