Standing up is one of the most common yet most mechanically demanding activities of daily living. Mobility impairments, in particular neurological conditions, often impede individuals ability to stand up independently. Electroencephalography (EEG) from 8 bipolar electrodes over motor cortex and electromyography (EMG) from 8 bilateral lower limb muscles were acquired from four healthy participants during sit-to-stand transfers. Event- related spectral perturbation (ERSP) and corticomuscular coherence (CMC) were calculated. Alpha waves (8–12 Hz) are observed during all phases of sit-to-stand. The bipolar electrodes that provided the most information are Fz- Cz, FCz- CPz, FC6- CP6 and FCs- CPs. Limited findings suggest that the motor cortex contributes to vastus lateralis activation during sit-to-stand.

摘要

Standing up is one of the most common yet most mechanically demanding activities of daily living. Mobility impairments, in particular neurological conditions, often impede individuals ability to stand up independently. Electroencephalography (EEG) from 8 bipolar electrodes over motor cortex and electromyography (EMG) from 8 bilateral lower limb muscles were acquired from four healthy participants during sit-to-stand transfers. Event- related spectral perturbation (ERSP) and corticomuscular coherence (CMC) were calculated. Alpha waves (8–12 Hz) are observed during all phases of sit-to-stand. The bipolar electrodes that provided the most information are Fz- Cz, FCz- CPz, FC6- CP6 and FCs- CPs. Limited findings suggest that the motor cortex contributes to vastus lateralis activation during sit-to-stand.
