The purpose of this study will be to assess the effects of an 8-week hypo-pressive abdominal exercise program on Inspiratory muscle strength, diaphragm thickness, pressure pain threshold and disability in patients with non-specific chronic low back pain. A randomized clinical trial will be carried out. A total sample of 40 patients with non-specific chronic low back pain will be recruited and divided into 2 groups including an experimental group (n=20) which will receive an 8-week hypo-pressive abdominal exercise program and a control group (n=20) which will not receive any training program. Inspiratory muscle strength, diaphragm thickness, pressure pain threshold and disability will be assessed.

An 8-week hypo-pressive abdominal exercise program
Universidad Francisco de Vitoria

Inspiratory muscle strength
Inspiratory muscle strength will be measured in % by a POWER-breathe device
Time frame: Change from baseline inspiratory muscle strength at 8 weeks
Diaphragm muscle thickness
Diaphragm muscle thickness will be measured in mm by an ultrasound device
Time frame: Change from baseline diaphragm muscle thickness at 8 weeks
Pressure pain threshold
Pressure pain threshold will be measured in kg/cm2 by an algometer
Time frame: Change from baseline pressure pain threshold at 8 weeks
Disability
Pain-related disability score will be measured by the Roland-Morris Disability Questionnaire. Total score ranges from 0 to 24. Higher scores represent higher levels of pain-related disability.
Time frame: Change from baseline disability at 8 weeks
