BACKGROUND: Studies have shown that obesity is associated with skeletal muscle pain, but the specific factors have not yet been discovered. OBJECTIVE: To analyze the possible development of latent myofascial trigger points in obese people. METHODS: Fifty-seven obese persons (aged 9-20 years) who participated in the summer camp of weight loss were investigated (for participants younger than 18 years old, written consent was obtained from their parents). Their body fat rate was more than 30%. A pressure algometer was used to measure the pressure pain thresholds at three different sites in the brachioradialis muscle: the lateral epicondyle at elbow (site A, assumed to be the A-TrP site), the mid-point of the muscle belly (site B, assumed to be the MTrP site), and the muscle-tendon junction as a control site (site C). In addition, 19 obese persons were selected randomly. They did the based exercise in badminton and table tennis in the next 2 weeks. RESULTS AND CONCLUSION: The results showed that, for all the obese participants in this study, the mean pressure pain threshold was lowest at the site B and highest at thesite C. For different genders, the pressure pain thresholds at the site A were significantly lower in the female than the male. With the increase of body mass index, the pressure pain thresholds at the site B was increased. However, no significant difference in the pressure pain thresholds at these three sites was found before and after exercise. It is concluded that the latent trigger point may appear in the brachioradialis after 9 years old. Women may be more likely to form the attachment trigger point in the tendon. Movement has no effect on the activation and elimination of latent trigger points. © 2014, Journal of Clinical Rehabilitative Tissue Engineering Research. All right resurved.
