Myofascial pain syndrome, or MPS, is a prevalent musculoskeletal disorder, which ischaracterised by the presence of muscle pain and tenderness. The inflammation andmicrotrauma that are the consequence result in adhesions between the fascial layers. Ithas been reported that these adhesions prevent the fasciae from sliding over each otherand contribute to pain.
The rhomboid and trapezius muscles are commonly involved in MPS, which often affects the
upper extremity.
This study hypothesized that muscle sliding decreases in patients with MPS. To this end,
the investigators measured the amount of fascial sliding of the trapezius muscle in
healthy volunteers and patients with MPS using M-mode ultrasound and a software-assisted
program to investigate the differences and diagnostic value.
Diagnostic Test: Ultrasound
M-mode ultrasonography images of the fascia under the trapezius muscle will be recorded
during 3 different movements.
Other Name: M-Mode musculoskeletal ultrasound
