A new meta-analysis of 241 people with spinal cord injury found that robot-assisted gait training improves walking ability more than conventional rehabilitation alone. The study combined results from several smaller trials to get a clearer picture of how well this technology works.
Participants who used robot-assisted training walked significantly farther on the 6-minute walk test and scored higher on the Spinal Cord Injury Walking Index II. They also showed greater improvement in functional independence, meaning they could do more daily activities on their own. However, lower limb motor scores were not significantly different between the two groups.
The analysis did not report any safety concerns, but the studies were small and the quality of evidence was not assessed in detail. Because this is a meta-analysis of existing research, it cannot prove that robot training caused the improvements. The results are promising but should be confirmed in larger, longer-term trials.
For now, the findings suggest that adding robot-assisted gait training to a rehab program may help people with spinal cord injury regain more walking function. Patients should discuss with their rehabilitation team whether this approach is right for them.
