GTQ – Gothenburg Trismus Questionnaire

Trismus (restricted mouth opening) is a symptom that leads to difficulties with chewing, swallowing, pain and poor oral hygiene and can have a negative impact on health-related quality of life, especially with regards to social function and social contact.

To evaluate trismus and its treatment outcomes, a multidimensional, self-administered, trismus-specific questionnaire has been created: Gothenburg Trismus Questionnaire (GTQ 2).

GTQ 2 can be used for all patients with restricted mouth opening and has in statistical testing shown good psychometric properties, i.e. high validity and reliability.

Translations and validation are currently underway in Chinese and French.
