Acute Static or PNF Stretching Does Not Decrease Cramp Susceptibility in Cramp-Prone Humans

An abstract of a study by Miller et al determining if no stretching or an acute bout of static stretching or proprioceptive neuromuscular facilitation (PNF) stretching increased threshold frequency (TFc) is presented. Both static and PNF stretching effectively increased hallux range of motion. However, neither stretching condition increased TFc. Thus, it is unlikely an acute bout of stretching provides a prophylactic effect against cramping.
