What this Trial Is About
This research aims to evaluate different control strategies of wearable lower limb rehabilitation robots for people who have experienced a stroke. The study focuses on identifying which method—Aware Hip Knee Coupling Control (AHKC), Passive control (PC), or fixed compliance control (FCC)—might be best for post-stroke patients with gait disorders. Participants must be medically stable and able to walk independently, reflecting the importance of improving walking ability after stroke. Participants will undergo robot-assisted gait training involving nine repetitions of 5-meter overground walking using each of the three different control strategies. This training occurs during a single session in a hospital corridor, allowing researchers to compare the effects of each robot control method on walking performance. The study does not use masking or placebo controls. During the study, researchers will measure changes in walking speed using the 10 Meter Walk Test before and immediately after the training session. They will also assess lower limb motor function using the Lower Extremity Fugl-Meyer Assessment. Participants will be monitored for their ability to tolerate the therapy and follow instructions. The total participation period centers on this single training session and immediate evaluation afterward.
