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

Comparative Effect of Diaphragmatic Training and Myofascial Release on Pain Flexibility and Disability in Patients With Chronic Non-specific Low Back Pain

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.

Inclusion Criteria:

• with intermittent nonspecific CLBP for ≥12 weeks, with VAS between 3 to 7. All participants will be active at a recreational level, history of at least 12 weeks of NLBP, absence of radiculopathy or spinal damage due to tumors, stenosis, or fractures, and a minimum level of physical activity to be able to perform the exercises.

Exclusion Criteria:

• lumbar surgery experience,
• inflammatory spinal disease,
• spinal deformities,
• neurologic radiating pain
