Brief Summary

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.

Conditions

Core Stability; Breathing Exercise; Low Back Pain

Outcome Measures

Primary Outcomes (1)

• 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.

  Baseline and after 4 weeks

Secondary Outcomes (1)

• Functional disability

  Baseline and after 4 weeks

Other Outcomes (1)

• Muscle activity

  Baseline and after 4 weeks

Study Arms (2)

The combined diaphragmatic breathing and trunk stabilization exercise group

EXPERIMENTAL

The combined diaphragmatic breathing and trunk stabilization exercise group performed trunk stabilization exercises consisting of dead bug, bridge, side plank, and bird dog, with additional diaphragmatic breathing exercise.

Behavioral: trunk stabilization exercise; Behavioral: diaphragmatic breathing exercise

The trunk stabilization exercise group

ACTIVE COMPARATOR

The trunk stabilization exercise group performed trunk stabilization exercises consisting of dead bug, bridge, side plank, and bird dog

Behavioral: trunk stabilization exercise

Interventions

trunk stabilization exercise BEHAVIORAL

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 BEHAVIORAL

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.
