PMID 37744200WHAT IT FOUND
Aerobic exercise did not significantly improve cardiorespiratory fitness in acute spinal cord injury.
However, functional electrical stimulation cycling reduced muscle loss and increased lean body mass. Strength training improved peak torque and perceived function. These interventions appear safe but evidence remains limited.
Key findings
01Aerobic interventions (HIIT and MIT) showed no statistically significant improvement in cardiorespiratory fitness measures, despite some observed increases in peak oxygen uptake.
02Functional electrical stimulation cycling (FES-CE) significantly reduced muscle atrophy and increased lean body mass compared to control groups at 3 and 6 months.
03Resistance training interventions improved peak muscle torque and perceived strength/function, though objective isometric strength changes were inconsistent.

What it does not show
Only 4 studies with a total of 108 participants were included, making the evidence base very small. Heterogeneity in outcome measures and intervention types prevented meta-analysis, relying instead on narrative synthesis. None of the included studies were fully blinded or concealed allocation, and no study received an 'excellent' quality rating. The sample was overwhelmingly male, which may limit generalizability to female patients, although this reflects the actual SCI population demographics. Time since injury and severity of injury varied across studies, and some did not report time since injury precisely.

The easy way to misread this
Do not assume that aerobic exercise is ineffective for acute SCI patients. The lack of statistical significance in cardiorespiratory fitness may be due to the small sample size and short duration of the included studies. Furthermore, do not expect immediate improvements in walking distance or daily step counts from aerobic training alone, as these functional outcomes were not significantly improved.
