Aims and objectives
Myofascial pain syndrome is a chronic condition characterized by tendomuscular pains mainly localized in the muscle attachment sites and having a widely spread irradiation to other parts of the body.
A chronic myofascial pain syndrome is gradually developed due to reduced muscle elasticity in the muscle attachment sites.
The pain essentially limits sportsmen’s functional abilities.
Objectives: To assess the diagnostic value of shear wave ultrasound elastography (SWE) in myofascial pain syndrome of different localization.
Keywords: High resolution ultrasound (HRUS),
Myofascial pain syndrome,
Shear Wave Elastography...
Methods and materials
45 professional sportsmen were enrolled in the study.
They were divided into 2 groups: the first group included 20 sportsmen with no signs of lower extremities muscle disease (control group),
and the second group included 25 sportsmen who experienced pain in the proximal muscles attachment sites of the outer and inner thigh.
Informed consent was obtained after the nature of the procedure had been fully explained.
The ultrasound examination was performed using the Aixplorer (Supersonic Imagine,
France) ultrasound system and linear probe (4–15 MHz).

Results
In the 1-st group the elasticity of thigh muscles at their bone attachment site (Me) was as follows: the proximal Gluteus muscle: Emean – 9,9kPa,
SD – 1,7 kPa (Tabl.1,
Fig.1);

Conclusion
Shear wave ultrasound elastography gives the possibility to obtain muscle degeneration information using not only grey scale imaging of the muscles but also the quantitative assessment of the muscle elasticity changes.
In sportsmen,
who develop the myofascial pain syndrome,
SWE data may be the helpful indicator for disease course monitoring.
