The influence of age and physical activity on the pressure sensitivity of soft tissues of the musculoskeletal system

Background: The pressure sensitivity of soft tissues is defined as the slightest pressure causing pain. Sex, movement system illnesses, pain ailments may influence the pressure sensitivity. However, there have been few studies on factors determining the level of pressure sensitivity of skeletal muscles. Objective: The authors have determined to study the influence of age and physical activity on the pressure sensitivity of skeletal muscles. Methods: The examination of pressure sensitivity of trigger points and muscle insertions was carried out using algometry. Results: 76 volunteers (38 students and 38 individuals aged 50-75) participated in the study. The differences in pressure sensitivity between students and people aged 50-75 were not statistically significant. Pressure sensitivity of students differed depending on their level of physical activity. Conclusions: The level of physical activity influenced the pressure sensitivity of skeletal muscles. Age did not significantly influence pressure sensitivity. (C) 2009 Elsevier Ltd. All rights reserved.
