Diagnostic algorithm for critical illness weakness (CIW). DD = differential diagnosis. CIM = critical illness myopathy. CIP = critical illness polyneuropathy. CMAP = compound muscle action potential. EMG = electromyography. MRC = Medical Research Council. NCS = nerve conduction study. NM = neuromuscular. Cut off handgrip strength values are below 7 kg for female and below 11 kg for males. For information on increased CMAP duration and direct muscle stimulation see Latronico N, Bolton CF [8]. Adapted from Latronico N, Gosselink R [35]
