Key facts

Voluntary activity.recruitment of Muscle on EMG
Voluntary activity.recruitment
With increasing patient effort, more motor units are typically recruited. Reduced recruitment may be caused by a variety of factors, including pain that limits contraction, poor effort, upper motor neuron lesions, and motor conduction block. Early recruitment is seen with primary muscle disease. [PMID15961866]
