Efficacy of exercise therapy during radiotherapy to prevent reduction in mouth opening in patients with head and neck cancer: A randomized controlled trial.

Objective: The aim of this study was to compare the efficacy of 2 protocols of exercise therapy to avoid reduction in mouth opening (MO) in patients undergoing radiotherapy for head and neck cancer.

Study Design: This was a randomized, controlled, double-blind, 3-arm, parallel-group, prevention clinical trial. Ninety patients were randomized into 3 groups to perform exercises during radiotherapy treatment: intervention group 1 (G1); intervention group 2 (G2); and control group (CG).

Jaw mobility changes in patients with upper aerodigestive tract cancer undergoing radiation therapy.

Background: Radiation therapy is a therapeutic modality widely used for treatment of upper aerodigestive tract (UADT) neoplasms. However, its action is not restricted to tumor cells, and it may cause a variety of adverse reactions, including reduced jaw mobility.

Material And Methods: A prospective cohort study was conducted to assess changes in jaw mobility in patients with UADT cancer undergoing radiation therapy.
