Elevated creatine kinase does not necessarily correspond temporally with onset of muscle rigidity in neuroleptic malignant syndrome: a report of two cases

Figures & data

Figure 1 Changes in serum creatine kinase level, muscle rigidity, and body temperature in case 1 (A) and case 2 (B).

Notes: Both patients with neuroleptic malignant syndrome showed nonsimultaneous occurrence of elevated serum creatine kinase (●) and onset of muscle rigidity (■).
