What works in post-stroke rehabilitation? – evidence-based principles High intensity, repetition, and task-specific walking practice form the foundation – recommended by AHA/ASA guidelines and the APTA Neurologic PT Clinical Practice Guidelines. Walking training assisted by electromechanical/robotic devices increases the chances of regaining independent walking (OR ≈ 2.0; NNT ≈ 8), especially in non-ambulatory patients and in the early post-stroke period. Improvement in walking speed is usually modest, and gains in distance are not always significant. Importantly, this is achieved without an increase in adverse events. In clinical practice, robots complement – but do not replace – overground physiotherapy, balance training, strengthening, endurance work, and functional therapy.
Why do gait rehabilitation robots help? Robots allow safe delivery of the necessary “dose”: hundreds to thousands of steps in a single session, with control over body weight support, gait phases, and feedback. This creates the conditions for neuroplasticity (motor learning) and reduces the manual workload for therapists. Studies have shown beneficial effects of RAGT on lower limb function, walking ability, balance, and – in some patients – markers of neuroplasticity.
1) GEO System / G-EO System (end-effector) How does it work? The patient’s feet are placed on independently driven plates. The system replicates gait phases, including stair ascent and descent as well as ramps. It works in passive, assisted, and active modes, with dynamic body weight support and advanced training protocols. Who is it for? From completely non-ambulatory patients (FAC 0) to independent walkers (FAC 5); pediatric/FES modules are also available. Why does it make sense? End-effector devices promote a high number of steps per session and enable progression (e.g., stair climbing). Studies of end-effector and exoskeleton devices combined have confirmed a higher likelihood of regaining independent walking compared to standard therapy.
2) RoboGait (often written as “Robo Gate”) – treadmill-based exoskeleton with body weight support How does it work? A computer-controlled exoskeleton guides the limbs through a physiological walking pattern, synchronized with the treadmill. It offers adjustable body weight support and limb assistance (including asymmetric support for hemiparesis). Evidence pathway: The evidence for robotic-assisted gait training as a class of intervention (both exoskeletons and end-effectors) is strong; however, head-to-head comparisons between models still yield mixed results – the choice should depend on the patient’s deficits and therapeutic goals.
