Overview
What It Is Robotic and exoskeleton gait training uses powered devices to help people practice walking with high repetition and adjustable support after neurologic injury. Systems include treadmill-based robotic orthoses and overground wearable exoskeletons.
How It Works High-dose, patterned stepping provides intensive sensory and motor practice that can support use-dependent plasticity in gait networks. Robots allow more steps per session than many patients could achieve unassisted, while therapists reduce assistance as recovery progresses.
Types - Treadmill-based robotic orthoses (e.g., Lokomat-class) — body-weight support + driven leg trajectories on a treadmill; common in inpatient/outpatient neurorehab gyms - Overground wearable exoskeletons (e.g., EksoNR, ReWalk, Indego) — powered hip/knee assistance for walking over ground; used in rehab and, for some devices, personal mobility in spinal cord injury - End-effector and hybrid systems — foot-plate or mixed designs that guide stepping without a full leg orthosis
On-label / care status - Multiple systems have FDA clearance for rehabilitation use in stroke, SCI, and related populations (device-specific labeling) - Used as an adjunct to skilled physical therapy; not a replacement for overground and community mobility training - Personal-use exoskeletons for SCI have separate indications and training requirements
Example technologies - Lokomat (Hocoma) — widely used treadmill-based robotic gait orthosis in clinical rehab centers - EksoNR (Ekso Bionics) — overground rehab exoskeleton used in stroke, SCI, and related gait training - ReWalk — wearable exoskeleton with rehab and personal-use pathways, especially for SCI - Indego (Ekso Indego) — modular powered exoskeleton for therapy and personal mobility applications
Conditions - Stroke, traumatic brain injury, spinal cord injury, and selected MS-related gait impairment - Medical screening required for weight-bearing, skin, and cardiovascular safety
How it is administered
Clinic-based sessions with a robotic gait orthosis or exoskeleton, supervised by physical therapists. Training blocks often involve multiple sessions per week over weeks to months.

Practical information
Insurance coverage
Sometimes covered when medical necessity for gait training is met; prior authorization common; coverage varies widely by device and plan.
Cost information
High when billed as specialized rehab technology; usually part of facility-based therapy costs rather than a consumer device purchase.
Results and outcomes described in the source record
Walking endurance and quality are typically reassessed over weeks of training; gains depend on baseline ability and intensity.
Side effects and risks
Skin irritation, fatigue, and device-related discomfort possible. Medical screening required; not appropriate for all weight-bearing or cardiovascular profiles.
Research context in the NPA database
This section reproduces the current database's research summary and detail. Structured citation metadata has not been supplied, so it should not be read as an independently verified literature review.
Research summary
Evidence Level: Moderate What the research shows: Robotic gait training can increase practice dose and improve gait parameters for some patients after stroke and SCI; superiority over equally intensive conventional therapy is not always shown. Best viewed as a tool to deliver intensity. Key takeaway: A high-dose gait practice technology that complements—not replaces—skilled overground therapy.
Research detail
Overview Robotic and exoskeleton systems deliver high-repetition gait practice with adjustable support after neurologic injury.
Evidence Base and Published Work • Clinical literature supports increased practice dose and gait improvements in selected stroke and SCI populations. • Comparative superiority over matched-intensity conventional therapy is mixed; value is often in enabling intensity. • Established clinical systems include Lokomat, EksoNR, ReWalk, and Indego, each with device-specific evidence and labeling.
Outcomes Outcomes most frequently described include more steps per session, improved gait speed or endurance in some cohorts, and access to walking practice when overground capacity is very limited.
Questions to ask a provider
1. Am I a candidate for robotic or exoskeleton gait training given my strength, tone, and medical status? 2. How does this compare with intensive overground or body-weight–supported treadmill therapy? 3. How many sessions per week and for how long? 4. Will insurance cover this technology at the recommended facility? 5. What overground or home walking program follows robotic training?
