Answer

Recording of voluntary recruitment of motor unit action potentials can provide additional information. Reduced recruitment signifies motor axonal loss or functional dropout due to focal demyelination or conduction block. By contrast, increased recruitment with a small voluntary force can be seen with myopathy.
