Exoskeletal-Assisted Walking in Veterans With Paralysis: A Randomized Clinical Trial.

Robotic exoskeletons that help people with spinal cord injury stand and walk have generated excitement, but whether using one at home and in the community actually improves wellbeing hasn't been tested in a randomized trial until now. This study compared veterans with spinal cord injury who used their wheelchair as usual against those who also had access to an exoskeleton for walking over four months, looking at whether either group showed meaningful improvements in mental health and physical quality of life scores. The proportion reaching a meaningful improvement was similar between groups for both outcomes, with no statistically significant difference detected.

A major factor was that actual exoskeleton use turned out to be much lower than planned, largely because a required companion person wasn't available nearly half the time. That usage problem makes it hard to say whether the device itself doesn't help or simply wasn't used enough to find out.

If you or someone you know uses a wheelchair after spinal cord injury, you may have heard about robotic exoskeletons that let a person stand and walk with assistance. This trial asked whether having one of these devices at home, in addition to a wheelchair, actually improves how people feel mentally and physically compared with using a wheelchair alone.

Veterans were randomly assigned to one group or the other and followed for four months. The result: similar proportions of people in both groups reported meaningful improvements in quality of life, so no clear benefit from the exoskeleton was detected in this trial. A big part of the story is that people didn't end up using the device much, mainly because a helper who was required to be present often wasn't available.

So this doesn't necessarily mean exoskeletons can't help, just that in this trial, low real-world use made it hard to see any benefit. A couple of foot fractures were linked to device use, alongside other unrelated fractures during wheelchair transfers.

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

This trial addresses a genuine gap in the evidence base for exoskeletal-assisted walking: whether unsupervised, at-will home and community use translates into patient-reported gains in mental or physical quality of life for people with spinal cord injury, rather than just demonstrating feasibility in supervised settings. In this randomized trial of 161 veterans (78 exoskeleton plus standard wheelchair care, 83 standard wheelchair care alone), the proportion achieving a predefined meaningful improvement on the mental health component of the Veterans RAND 36-Item Health Survey and on the physical and medical health domain of the Spinal Cord Injury-Quality of Life measure did not differ significantly between groups at four months. What stands out clinically is the usage problem: mean device use was only about 1.5 miles per month, substantially below expectation, with the FDA-mandated companion unavailable in nearly 44% of attempted sessions.

This raises an important distinction for clinicians advising on exoskeleton adoption, that the null result reflects a trial of low real-world adherence rather than clear evidence that the technology itself cannot help when used as intended. The study does not establish efficacy or lack of efficacy of exoskeletal walking under adequate dosing, nor does it resolve whether companion requirements and device usability are the primary adoption barriers. Adverse events included two exoskeleton-related foot fractures among other unrelated fractures, mostly during wheelchair transfers.
