Summary

This study focuses on patients with a primary complaint of hyperacusis. Hyperacusis has been defined as 'abnormally reduced tolerance to sound' and is commonly associated with tinnitus. The effects of somatic modulation upon tinnitus have been studied, but not so for hyperacusis.. The effect of 9 somatic modulations (i.e. 3 jaw modulations and 6 cervical spine modulations) and 1 control movement (i.e. without any somatic modulation effect) in random order on the sound tolerance of a 1 kilohertz (kHz) broadband noise sound and the tinnitus experience will be investigated. More specifically, the perceived loudness and intrusiveness of this sound and the tinnitus sound will be evaluated before somatic modulation and during the somatic modulation.

Conditions

• Hyperacusis

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Somatic modulation	Type of modulations: 3 jaw and 6 cervical spine modulations, 1 control movement (i.e. without any expected somatic modulation effect) Jaw modulations: laterotrusion to the left, laterotrusion to the right and protrusion Cervical spine modulations: isometric flexion, extension and left and right lateroflexion of the head against resistance of the investigator's hand, compression and traction of the cervical spine in sitting position. Control movement: the investigator's hand rests against the patient's forehead without any force application
