title: Leg volume changes with EPIC and posturing in dependent pregnancy edema.
abstract: This study explored the differential effects of external pneumatic intermittent compression (EPIC) and posturing on leg volume changes in healthy pregnant women with dependent leg edema. Thirty-five healthy pregnant women with severe pedal edema were randomly assigned to one of two treatment groups. The experimental group (n = 17) received EPIC for 30 minutes at 40 torr while in the left lateral recumbent position. Control women (n = 18) were similarly positioned, but received no EPIC. Both groups walked for 10 minutes following left lateral posturing. Circumference measures required for leg volume estimates were made: prior to posturing (Time 1), immediately after posturing (Time 2), and following the ambulation period (Time 3). Volume losses for the experimental group were greater than for the control group at Time 2. Although volume losses for the experimental group had reversed somewhat at Time 3, they remained greater than control group losses, which did not change from Time 2 to Time 3. Analysis of covariance revealed significant mean volume losses for both experimental and control groups, with ponderal index the only significant covariate.
