Accepted Answer

A) Small polyphasic potentials observed with voluntary contraction 
B) EMG changes that occur after changes are observed with manual muscle testing 
C) An interference pattern that occurs very slowly during the test 
D) Decreasing numbers of motor unit action potentials with contraction
