Radio pills: their use in monitoring back stress.

A system for the quantitative assessment of spinal stress during manual materials handling has been developed. This has been achieved using radio pressure pills and is applicable to both laboratroy and field use for establishing safe general handling procedures and defining safe maximum loads.

Intraabdominal pressure rise during weight lifting as an objective measure of low-back pain.

Twenty-three male patients who had chronic nonspecific low-back pain were asked to record the amount of pain they felt on an arbitrary scale while lifting light weights in different directions. During the lifts their intraabdominal pressures were recorded with an intragastric transducer. The patients who experienced extra pain during the lift had higher rises of pressure than both normal controls and those patients who did not experience extra pain. The available evidence suggests that this pressure rise may be a response to low-back pain and may be used as a method of objectively measuring that pain.
