The persistence of the effect after the end of therapy, in spite of the previous plateau, fur- ther supports this interpretation, and is consistent with previous evidence that task-oriented training leads to the integration of functional gains into mobility strategies at home and in the community [16-19]. Lack of TUG improvement may have been due to the absence of specific training for quick directional changes and short-latency start and stop practice during walking. It is also possible that the tests used to measure balance were not sensitive enough to document changes in per- formance or confidence. Post-training knee extensor strength was not assessed. No adverse events were noted during training. At the end of the training sessions, participants reported phys- ical fatigue, attributable to the intensive physical activity during training. All participants reported positive experi- ences regarding their interaction with the RLO. Each indicated the RLO training made it easier for them to stand up, sit down and walk, not only during therapy but also at home and in the community. Conclusion For patients who are stable after a stroke, this study investigated the benefit of intentional, task-oriented, untethered gait training with a novel, wearable, mobile RLO designed to assist knee function during transitional movements, walking, coordinated movements and stair climbing. The device was integrated into the rehabilita- tive process to actively assist hemiparetic patients to im- prove functional mobility and gait skills after they had plateaued with physical therapy including BWSTT. These results suggest additive clinical-functional benefits may be achieved by incorporating mobile, intention- based robotic technology into therapist-supervised mo- bility training for patients in the late-phase post stroke. Abbreviations BWSTT: bodyweight-supported treadmill training; FTSTS: five times sit-to-stand; RLO: robotic leg orthosis; TUG: timed up and go.
