Effectiveness of Combined Diaphragm Strengthening and Core Stability Exercises in Individuals With Lumbar Instability
25 de julio de 2026 actualizado por: Ahmed Hesham abd el-Mawgoud, Cairo University
The purpose of this study is to compare the effect of combining diaphragmatic strengthening with core stability exercises versus core stability exercises alone on recovery time, pain, and stability in lumbar instability individuals.

Descripción detallada
Lumbar instability is a common medical problem. There is a 50-70% chance of a person suffering from LBP during his or her lifetime having lumbar instability. It is often referred to as clinical spinal instability. Clinical spinal instability is controversial and poorly understood. Properly conducted clinical studies of patients with spinal pain and documented clinical instability would be good to explore this concept. However, pursuing such a course is difficult.
The diaphragm has a dual role in respiration and postural control. Evidence suggests that current core stability exercises for low back pain are superior to minimal or no treatment, however, no more beneficial than general exercises and/or manual therapy. There appears to be a higher focus on the transverses abdominis and multifidi muscles and minimal attention to the diaphragm.
We propose that any form of core stabilization exercises for low back pain rehabilitation should consider the diaphragm. Core stabilization program could commence with facilitation of normal breathing patterns and progressive systematic restoration of the postural control role of the diaphragm muscle.
So, the aim of this trial is to determine whether combining diaphragmatic strengthening exercises with core stability training leads to faster improvements in pain and instability in individuals with lumbar instability, compared to traditional core exercises alone.

Experimental: Combined diaphragm strengthening + Core stability exercises
It will include patients that will perform combined diaphragm strengthening and core stability exercises.
The treatment program will be 45 minutes, 3 times a week, for 8 weeks.
|
Participants will receive supervised diaphragm strengthening exercises combined with core stability training, three sessions per week for 8 weeks (45 minutes/session).
Diaphragm strengthening will be performed using an elastic TheraBand wrapped around the thoracolumbar junction to provide progressive inspiratory resistance, with intensity progressed according to the Borg Rating of Perceived Exertion (RPE: 11 during weeks 1-2, 13 during weeks 3-5, and 15 during weeks 6-8).
Participants will receive supervised core stability exercises only, three sessions per week for 8 weeks (45 minutes/session).
The exercise program includes the abdominal drawing-in maneuver (ADIM), side-bridge, and quadruped exercises, with progressive increases in exercise difficulty every two weeks.
Participants will perform the same exercise progression as the intervention group but without diaphragm strengthening or TheraBand resistance.

Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Pain intensity assessed using the Visual Analogue Scale (VAS)
Periodo de tiempo: 8 weeks
|
Pain intensity will be evaluated using a 10-cm Visual Analogue Scale (VAS), with scores ranging from 0 (no pain) to 10 (worst imaginable pain).
Higher scores indicate greater pain intensity.
|
8 weeks
|
|
Pressure pain threshold assessed by pressure algometry
Periodo de tiempo: 8 weeks
|
Pressure pain threshold will be measured over the lumbar paraspinal muscles using a handheld pressure algometer.
Higher values indicate reduced pain sensitivity.

|
Core muscle stability assessed using a Pressure Biofeedback Unit (PBU)
Periodo de tiempo: 8 weeks
|
Core muscle stability will be assessed using a Pressure Biofeedback Unit during abdominal drawing-in tasks.
Improved pressure control indicates better activation of the local stabilizing muscles.
|
8 weeks

|
Functional disability assessed using the Oswestry Disability Index (ODI)
Periodo de tiempo: 8 weeks
|
Functional disability related to low back pain will be evaluated using the Oswestry Disability Index (ODI).
Scores range from 0 to 100%, with higher scores indicating greater disability.
