PMID 41749348WHAT IT FOUND
Walking patterns in 28 adults with incomplete spinal cord injury separated into six groups, from close to control gait to reduced toe-off ankle motion.
The Pink and Green groups walked as fast and as far as controls.
Key findings
01Gait patterns formed six clusters with 80, 65, 50, 45, 25, and 15 patterns.
02The Pink and Green clusters showed no significant walking speed or step length differences from controls.
03Less ankle plantarflexion at toe-off was the most frequent feature separating clusters from controls and correlated strongly with walking speed and step length.

What it does not show
Only 28 adults with incomplete spinal cord injury were analysed, all classified as AIS D, so the clusters may not represent people with more severe walking limitations. The group was highly functional: 21 of 28 reached the maximum WISCI II score, and 23 walked barefoot during testing. The number of clusters depended on a threshold chosen by visual inspection, and using fewer gait cycles changed cluster membership for 6 of 56 limbs. Each side was treated as a separate observation, so the left and right sides of one person were not analysed as one person. The study tested no treatment, so it cannot show that any exercise, orthosis, or intervention improves walking. Ground reaction forces and joint kinetics were not analysed, so causes of the observed gait deviations were not established.

The easy way to misread this
Do not read the six clusters as proven treatment targets or as evidence that any exercise or orthosis improves walking. The study observed 28 highly functional adults with incomplete spinal cord injury, used an exploratory grouping method, and tested no treatment.
