摘要

•A microprocessor moved socket panels radially outward and inward during each step.•Most participants gained fluid volume while walking when cyclic panel-pull was added.•Most participants gained less fluid volume when the liner was not fastened to the panels.•Long-term testing during at-home use should be pursued using a simplified mechanism.
