Radiologist here. We actually put patients in LPO (left side down oblique on your back ) followed by RPO to elicit reflux to catch it on the xray camera.

The opposite is RAO (right side down on belly oblique), when we want to show the opposite esophageal emptying into the stomach.

But any one position is probably not good to maintain for a long time. That’s why patients on respirators get turned so they don’t develop pressure ulcers.

Personally I have found 15-20 minutes prone (on my belly) is helpful reducing fatigue after intense exercise.
