Robot-assisted gait training on functional ambulation in patients with stroke: a retrospective real-world analysis across five robotic devices.

PMID 42151953WHAT IT FOUND
Robot-assisted gait training did not improve walking outcomes overall compared to conventional therapy.
However, specific devices matched to patient function, particularly Exowalk and Morning Walk, were associated with better ambulation gains in this retrospective analysis.
Key findings
01In the overall adjusted analysis, robot-assisted gait training was not significantly associated with improved functional ambulation compared to conventional physical therapy.
02Patients assigned to the Exowalk and Morning Walk devices had significantly higher odds of achieving functional ambulation improvement compared to those receiving conventional treatment alone.
03Patients assigned to the Erigo device had significantly lower odds of achieving functional ambulation improvement compared to the conventional treatment group.

What it does not show
The study was retrospective and non-randomized, meaning treatment assignment was based on clinical judgment. This introduces significant selection bias, as the RAGT group had worse baseline function than the control group. Device-specific analyses involved multiple comparisons without formal adjustment, making these findings exploratory and hypothesis-generating rather than definitive. The study was conducted at a single center with a specific portfolio of five devices, limiting generalizability to other institutions with different equipment or protocols. Missing data in functional scales led to the exclusion of 475 patients from the regression models, potentially biasing results if missingness was related to severity. The number of therapy sessions differed significantly between groups (control: 37.4 ± 48.8; RAGT: 21.2 ± 44.0), which is a major confounder for intensity of rehabilitation.
Declared interests
The authors declared no competing interests. The study was approved by the institutional review board of Severance Hospital, and informed consent was waived due to the retrospective design.
The easy way to misread this
Do not conclude that specific robots are superior to conventional therapy based on this study. The overall finding was null, and the positive results for Exowalk and Morning Walk are from exploratory subgroup analyses in a non-randomized cohort where the RAGT group had worse baseline function and fewer therapy sessions than the control group.
