What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
trunk stabilization exerciseBehavioural
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 exerciseBehavioural
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.
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: 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 Receives: Behavioral: trunk stabilization exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Baseline and Week 4
Secondary outcomes (1)
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).
Measured: Baseline and Week 4
