Effects of combined chest expansion and breathing exercises in a patient with sternal pain.
Won-Gyu Yoo
PMID 28932017WHAT IT FOUND
In one woman with sternal pain, after 15 days of chest expansion and breathing exercises, her pain score fell from 7 to 2 and kyphosis angle dropped from 42° to 33°.
This is one case, not proof the exercises caused it.
Key findings
01After 15 days of combined chest expansion and breathing exercises, the participant's thoracic kyphosis angle was 33° compared with an initial angle of 42°.
02After the exercises, the participant's sternal pain VAS score was 2 compared with an initial score of 7.

What it does not show
Only one person was treated, so the paper cannot separate the exercises from other causes of change. This is a case report, so there was no comparison group or random allocation. The paper reports only initial and post-programme values, so it does not show whether the changes persisted. The participant had continued pain for 2 months before the programme, and the paper does not report other treatments or activities during the 15 days.
The easy way to misread this
Do not conclude that combined chest expansion and breathing exercises reliably reduce sternal pain or kyphosis in patients. This is one case report, and no comparison group or random allocation was described.
