Muscle adaptations in acute SCI following overground exoskeleton + FES training: A pilot study.
Kristen Hohl, Andrew C Smith, Rebecca Macaluso and 6 others
PMID 36311207WHAT IT FOUND
Adding exoskeleton and electrical stimulation to standard care helped six people with acute spinal cord injury build leg muscle volume.
It also improved static balance. However, the study was too small to prove these changes were real or to confirm the treatment works.
Key findings
01Muscle volume increased significantly more during the intervention period than the control period.
02Static balance improved more in the intervention group than the control group.
03The reduction in muscle fat infiltration showed a trend but did not reach statistical significance.

What it does not show
Very small sample size (n=6) limits generalizability. Heterogeneous injury levels and severities (AIS A-D). No washout period between intervention and control phases, risking carryover effects. Study was likely underpowered to detect differences in muscle fat infiltration. MRI cost and complexity limit routine clinical use. Participants could not complete walking outcomes, relying on static balance measures.

The easy way to misread this
Do not interpret the muscle volume increase or balance improvement as definitive proof that this intervention works for acute SCI. The study was a pilot with only six participants, no washout period, and mixed results for fat infiltration, meaning these findings are preliminary and require larger trials to confirm efficacy.
