Implication
Anticipatory diaphragmatic activation precedes rapid shoulder flexion; extends basic physiology of postural control but leaves clinical implications open.
Structured PICO

P
Population
Standing human subjects
I
Intervention
Rapid flexion of the shoulder to a visual stimulus
O
Outcome
Response of the diaphragm (EMG activity, gastric, oesophageal and transdiaphragmatic pressures, and dynamic changes in length)surrogate
The human diaphragm is involved in the control of postural stability during sudden voluntary movement of the limbs.
