Overground Robotic Exoskeleton Gait Training in People With Incomplete Spinal Cord Injury During Inpatient Rehabilitation: A Randomized Control Trial.

After a spinal cord injury, one of the biggest questions in inpatient rehabilitation is whether robotic exoskeletons help people walk better than standard gait training does. This trial compared an overground robotic exoskeleton program with usual care approaches, such as body-weight support treadmill training and traditional overground work, in people recovering from incomplete spinal cord injury during inpatient rehab. Both groups improved over the course of rehabilitation on measures of walking function, walking speed, and functional independence, but the study did not detect a statistically significant difference between the two approaches on these primary or secondary outcomes. A more mixed picture appeared when looking at injury severity subgroups: people with a specific, less severe injury category (AIS C) showed some within-group improvements in the exoskeleton group that were not mirrored in the usual care group.

However, this was a subgroup finding, not the trial's main comparison, and it does not establish that the exoskeleton was better overall. The main limitation is that despite improvements in both groups, this trial does not show one gait training approach outperforming the other for most patients.

If you or someone you know is recovering from an incomplete spinal cord injury, you may wonder whether walking practice using a robotic exoskeleton machine works better than standard therapy techniques like treadmill training with body support or regular overground walking practice. This study followed a group of adults in inpatient rehabilitation and compared these two approaches. Both groups got better over time at walking function, walking speed, and everyday independence.

But when researchers compared the exoskeleton group directly to the usual care group, they did not find a difference between them that reached statistical significance. In other words, both approaches seemed to help, but neither was shown to work clearly better than the other for the group as a whole. There was one exception worth mentioning carefully: among people with a particular injury severity category, some measures improved more in the exoskeleton group.

This was a smaller, subgroup observation, not the main result, so it should not be read as proof that exoskeletons are better for that group. Overall, the evidence here does not favor one gait training method over the other.

This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.

This trial addresses a question relevant to inpatient spinal cord injury rehabilitation: does overground robotic exoskeleton gait training produce better walking outcomes than existing usual care approaches, including body-weight support treadmill training and traditional overground methods? In a randomized controlled trial of 106 patients with subacute incomplete spinal cord injury, both the exoskeleton and usual care groups showed statistically significant within-group improvement on the Walking Index for Spinal Cord Injury, 10-meter walk test, and Spinal Cord Independence Measure. Critically, the abstract reports no statistically significant difference between the exoskeleton and usual care groups on these primary or secondary outcomes, meaning the trial does not demonstrate that the exoskeleton produced superior walking recovery compared with usual care. A subgroup analysis by injury severity found that, among patients classified as AIS C, the exoskeleton group showed statistically significant improvement on the WISCI-II and SCIM, while the usual care group in that subgroup improved only on the SCIM.

For AIS D patients, both groups improved across all three primary measures. Moderate effect sizes were noted for transfer and walking items on a functional independence tool (the CARE Tool) favoring the exoskeleton in the AIS C subgroup, though this is an exploratory subgroup finding rather than the trial's confirmatory result. Clinically, this suggests the exoskeleton did not demonstrate an overall advantage over usual care gait training in this population, and any signal favoring its use in less severely impaired patients (AIS C) should be interpreted as hypothesis-generating rather than established practice guidance.
