Article Synopsis
- FES cycling may improve muscle strength and fatigue resistance in individuals with spinal cord injuries, but measuring muscle fatigue during this process isn't well understood.
- This study involved six participants with SCI who cycled for 30 minutes while using sensors to measure their muscle activity (MMG) and oxygen levels (NIRS).
- The results revealed a moderate negative correlation between muscle activity and oxygen levels, with significant changes in these measurements before and after FES cycling, indicating that MMG could effectively track muscle fatigue and oxygenation during exercise.
Background: Repetitive electrically-evoked muscle contractions lead to the early onset of muscle fatigue. This study assessed the relationship between muscle mechanomyography (%RMS-MMG) and tissue oxygen saturation (%TSI) in extensor carpi radialis (ECR) during electrically-evoked fatiguing exercise in individuals with tetraplegia.
Methods: Skin-surface mechanomyography (MMG) and near-infrared spectroscopy (NIRS) sensors were placed on the ECR of seven individuals with tetraplegia.
This study compared muscle oxygenation (StO2) during arm cranking (ACE), functional electrical stimulation-evoked leg cycling (FES-LCE), and hybrid (ACE+FES-LCE) exercise in spinal cord injury individuals. Eight subjects with C7-T12 lesions performed exercises at 3 submaximal intensities. StO2 was measured during rest and exercise at 40%, 60%, and 80% of subjects' oxygen uptake (VO2) peak using near-infrared spectroscopy.
