Rehab effect. TFT effects pre (light), mid-way (hatched), and post (dark) home trial, for 6 min walk (6 MWT) test, timed stair test (TST-up) and timed up and go test (TUG). Test results are without using Keeogo™ (cWO). Home trial interventions are shown by the inverted triangle, where the green triangle represents 2-weeks home with Keeogo (hW), and the red triangle represents 2-week home without Keeogo (hWO). Error bars represent 95% confidence intervals. Results are shown for test sequence groups A and B (note the sequence of hW and hWO differed for A and B). In all cases the largest improvements were seen after 2-weeks hW
