Definition

The TORQUE torsion index measures the differential activity of the right temporal and of the left masseter in relation to the antagonist pair. As a consequence, it can be used as a potential indicator of lateral displacement forces, which in the long run, if underestimated, can influence the rehabilitative treatments that are performed on the Patient.

 

Example aspects

A prevalence of the right temporal and left masseter muscles can result in twisting forces on the mandible with latero-deviation to the right; in this case the torsion index will be positive.

A dominance of the left temporal and right masseter muscles will be visualized by a negative TORQUE index, indicating twisting forces to the left.

95% of healthy subjects show TORQUE values between + 10% and -10%.
