Impact of aging and body mass index on upper extremity motor unit number index and size

Impact of aging and body mass index on upper extremity motor unit number index and size

The focus of this study was to evaluate motor unit number and size across the upper extremity in older adults (aged 60+ years) versus young healthy adults (aged 20–30 years). We hypothesized that older adults would have: fewer motor units and increased motor unit size as compared to young healthy ad...
