PMID 31527999WHAT IT FOUND
Stronger knee extension, shorter foot off-loading, and no heart disease were linked to walking at discharge in 125 patients after revascularization, minor amputation, and physical therapy.
Key findings
01Of 125 patients, 72 were ambulatory and 53 were non-ambulatory.
02Knee extension strength, foot off-loading period, and heart disease were selected as factors influencing ambulatory state.
03The model's discriminant predictive value was 75.6%.

What it does not show
Single facility, so other hospitals may see different results. Retrospective record review, and the rehabilitation programme's influence was not sufficiently examined, so it cannot show what caused the difference in walking. Of 198 patients, 73 were excluded, including those with major amputation, death, systemic complications, infection, or prior wheelchair use, so the findings apply only to the selected group. The model's 75.6% discriminant predictive value is not certainty for any individual patient.
Declared interests
All authors declared no conflict of interest.
The easy way to misread this
Do not read the 75.6% predictive value as proof that stronger knee extension or shorter foot off-loading causes better walking. This was an observational record review, and it cannot separate the contribution of revascularization, minor amputation, and physical therapy.
