Summary

Diagnoses and follow up of muscles diseases lack imaging. Severity assessment of masticatory dysfunction and follow up of treatment effectiveness is currently based only on clinical features. Supersonic ShearWave Imaging® is a new, non-invasive, non-irradiating and dynamic imaging technique that uses ultrasound and allows shear wave elastic modulus in a muscle in order to study its viscoelastic properties. In this study, the investigators study the correlation between changes of shear wave elastography modulus and surface electromyogram features of the masseters between rest and maximal voluntary contraction.

Conditions

• Masseter Muscle Spasm

Interventions

Type	Name	Description
DEVICE	Ultrasound exam by Supersonic Shear Imaging® technique	Each of the two observers performs twice ultrasound examination and measures of the masseter thickness and its elastic modulus, at rest and maximal voluntary contraction.
DEVICE	EMG examination by electromyograph Keypoint system	Experimented neurologist performs EMG examination.
