Trial Outcomes & Findings for An Investigation of Functional Improvements in the RHEO KNEE Compared to Hydraulic Microprocessor Controlled Knees (MPKs) (NCT NCT04023578)

NCT ID: NCT04023578

Last Updated: 2020-04-06

Results Overview

The 6MWT is simply a record of the distance traveled by a given patient at his or her self-selected walking speed over a period of six minutes. All that is required is a stopwatch and a walking corridor or track of known distance. Those administering the test should avoid walking with or in front of test subjects to avoid pacing individuals outside of their self-selected walking speed. The outcome of the test is the distance walked in 6 minutes, in meters.
