PMID 42040652WHAT IT FOUND
One young man with incomplete paraplegia gained function and bone density over six months of exoskeleton training.
However, his visceral fat rose sharply and muscle asymmetry worsened. This single case shows functional gains can coexist with metabolic decline and uneven recovery.
Key findings
01Functional mobility and independence improved significantly, with the 6-minute walk distance increasing from 182 to 300 meters and the Functional Independence Measure score rising from 68 to 96 points.
02Lumbar bone mineral density increased by 50% (from 0.88 to 1.32 g/cm2), but visceral fat increased by 359% (from 91 to 418 g) during the same period.
03Muscle asymmetry worsened, with the bilateral deficit increasing from 12% to 42%, indicating that the right side recovered while the left side declined.

What it does not show
This is a single case report, so the findings cannot be generalized to other patients. The intervention combined exoskeleton training with conventional physiotherapy, making it impossible to separate the effects of the robot from the standard therapy. Dietary habits and physical activity outside of therapy sessions were not recorded, which may explain the increase in visceral fat. There was no control group or baseline comparison period, weakening the ability to attribute changes solely to the intervention. Patient-reported outcomes like quality of life were not systematically measured using standardized tools.

The easy way to misread this
Do not assume that functional gains in exoskeleton training guarantee overall physiological health. In this case, the patient improved in walking and independence while simultaneously gaining significant visceral fat and worsening muscle asymmetry. A therapist might see a patient walking further and assume they are getting healthier, but this case shows metabolic and neuromuscular risks can increase even as mobility improves.
