The purpose of this study was to investigate the effects of combined diaphragmatic breathing and trunk stabilization exercises on pain, function, and muscle activity in patients with chronic low back pain, and to compare its clinical effectiveness with trunk stabilization exercise alone.

Trunk stabilization exercises consisting of dead bug, bridge, side plank, and bird dog were performed for 10 repetitions in 3 sets, while the side plank was performed for 5 repetitions with a 10-second hold for 3 sets. Rest intervals between sets were set at 1 minute.
diaphragmatic breathing exercise was performed in a crook-lying position with one hand placed on the sternum and the other on the abdomen. Participants were instructed to inhale through the nose for 5 seconds, allowing lateral expansion of the rib cage, and exhale through pursed lips for 10 seconds while minimizing chest movement. The breathing exercise was performed for 10 repetitions in 3 sets with 1-minute rest between sets.

pain intensity
Pain intensity was measured using the Visual Analogue Scale (VAS), a 0-10 cm scale where 0 indicates no pain and 10 indicates the worst imaginable pain.
Time frame: Baseline and Week 4
Functional disability
Functional disability was assessed using the Korean version of the Oswestry Disability Index (KODI). The total score ranges from 0 to 100, with higher scores indicating greater disability. Disability levels are interpreted as follows: 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippled), and 81-100 (bed-bound or exaggerating symptoms).
Time frame: Baseline and Week 4
