Effect of lumbar stabilization with and without abdominal drawing-in maneuver on functional disability, respiratory parameters and posterior oblique sling EMG of subjects with non-specific chronic low back pain.
Comparison of the effects of eight weeks of lumbar stabilization exercises with and without the abdominal drawing-in maneuver on pain, functional disability, respiratory capacities (FVC, FEV1), and electromyographic activity of the posterior oblique sling muscles during hip extension in individuals with chronic low back pain
Design
The study is a quasi-experimental, parallel-group clinical trial (two training groups) with purposive sampling.
Settings and conduct
The present study was conducted at the Specialized Sports Science Laboratory of Yazd University in Yazd, Iran.
Participants/Inclusion and exclusion criteria
Inclusion criteria:
Individuals aged 30 to 45 years
Diagnosis of non-specific chronic low back pain for at least 3 months
Ability to perform the exercises (with medical approval from a specialist to participate in the training protocol)
Pain level ranging from 25 to 50 on the Quebec scale
Exclusion criteria:
Severe or noticeable musculoskeletal deformities in the spine
History of spinal surgery
Intervention groups
The training protocols were conducted in two groups: lumbar stabilization exercises with and without the abdominal drawing-in maneuver. Both groups performed the exercises with identical warm-up and cool-down routines, under full supervision, for 8 weeks, 5 days per week.
The main exercises included Bridge, Bird Dog, Dead Bug, Kneeling Shoulder Taps, and Side Plank. Participants in the abdominal drawing-in group performed each of these exercises while maintaining the abdominal drawing-in maneuver.
Main outcome variables
The effects of lumbar stabilization exercises with the abdominal drawing-in maneuver on various parameters related to chronic low back pain.
