Myofascial Trigger Points of the Levator Scapulae Muscle

May 3, 2023 updated by: JORGE VELAZQUEZ SAORNIL, Universidad Católica de Ávila

Sonoelastography, Tensiomyography and Mechanosensitivity Between Latent, Active and Control Trigger Points in Myofascial Trigger Points of the Levator Scapulae Muscle.

Chronic neck pain (CNP) is considered one of the most common musculoskeletal disorders worldwide and myofascial pain syndrome (MPS) is the most prevalent musculoskeletal disorder in the majority of the population. However, normal tissue contractility changes and the different types of myofascial trigger points (MTrPs) measured by tensiomography have not yet been studied. For this reason, the aim of our study is to determine the differences in pressure pain threshold (PPT), tensiomyography and sonoelastography between the palpation zone of control points with respect to active and latent MTrPs in the levator scapulae muscles of subjects with CNP. A single-blind descriptive cross-sectional study is conducted with a convenience sample of 60 points (20 active, 20 latent and 20 control points) on both sides of the subject in the levator scapulae muscles of individuals diagnosed with CNP.

The order of outcome measurements for each point was PPT, manual tension index sonoelastography and tensiomyography separated by 15 minutes. Objective contractile parameters were: contraction time (Tc), mean relaxation time (Tr), maximum radial displacement (Dm), holding time (Ts) and delay time (Td).
