Kao M-J, Han T-I, Kuan T-S, Hsieh Y-L, Su B-H, Hong C-Z. Myofascial trigger points in early life. Objective: To determine whether latent myofascial trigger points (MTPs) can be identified in healthy infants and in healthy adult subjects. Design: Blind comparison. Setting: Ambulatory. Participants: A convenience sample of 60 healthy adults and 60 infants (age range, 0-12mo). Interventions: Not applicable. Main Outcome Measures: An algometer was used to measure the pressure pain threshold (PPT) on 3 different sites, including a midpoint (assumed to be the MTP site) in the brachioradialis muscle. Results: The mean PPT values at the MTP site were significantly lower than the other sites in the adult muscles. However, no significant differences in PPT values among these 3 sites were found in the infants. Taut bands were found in all the adult muscles but none in the infants. Conclusions: In the adult subjects, the midpoint of brachioradialis muscle was significantly more irritable than other sites and the midpoint was probably a latent MTP. However, in the infants younger than 1 year old, such a phenomenon could not be observed in this study. It is very likely that the latent MTPs might not exist in early life, but develop in later life.
