Brief summary

This study will investigate the effect of Expiratory Muscle Strength Training (EMST) on Maximum Expiratory Pressure (MEP) as well as swallowing safety and voice function in head and neck cancer (HNC) survivors with dysphagia Who is it for? You may be eligible to join this study if you are aged 18 years or above, have survived head and neck cancer, completed treatment (surgery and or chemoradiotherapy) more than 3 months ago and are experiencing associated dysphagia (difficulty swallowing). Study details: All participants in this study will receive an Expiratory Muscle Strength Training device (EMST150) to use 5 days a week over 5 weeks at home, Participants will be required to attend a 1-hour in-person speech pathology appointment week 1 and 5 of the study, with weekly 15-minute telehealth consultations week 2, 3 and 4. Participants will undergo some testing procedures pre and post the 5-week EMST therapy period to determine maximum expiratory pressure, swallowing safety, voice function and quality of life.

Interventions

Description: The Expiratory Muscle Strength Training device (EMST150) is a one-way, adjustable spring-loaded valve that creates resistance against expiration. Its objective is to train the muscles required for exhalation, improving their capacity for coughing and swallowing. Dose and Duration: To use the hand-held device, patients take a deep breath and blow forcefully into the mouthpiece 5 times, 5 times a day, 5 days a week, for 5 weeks. Using the rotating knob, the device is calibrated to

Description: The Expiratory Muscle Strength Training device (EMST150) is a one-way, adjustable spring-loaded valve that creates resistance against expiration. Its objective is to train the muscles required for exhalation, improving their capacity for coughing and swallowing. Dose and Duration: To use the hand-held device, patients take a deep breath and blow forcefully into the mouthpiece 5 times, 5 times a day, 5 days a week, for 5 weeks. Using the rotating knob, the device is calibrated to the optimum resistance for training, which is 75% of the patient’s maximum expiratory pressure. No other speech pathology interventions will be provided during the 5-week period. Mode of Delivery: EMST is a speech pathology led intervention. The therapy program begins with a 1-hour in-person outpatient appointment with the speech pathologist, whereby baseline swallow and voice function measures are collected. Then, the EMST150 device is calibrated to the optimum training resistance by the speech pathologist and the participant is taught how to use the device. After initial consultation, the participant completes the training in their home, and the speech pathologist provides weekly 15-minute telehealth appointments to recalibrate the device as necessary and ensure adherence to the training program. At the completion of the 5-week therapy program, participants attend a 1-hour in-person outpatient speech pathology appointment to repeat swallow and voice function measures and establish a maintenance program. Materials: Prior to commencing the therapy program, patients will be provided with - Patient information sheet outlining the aims of the proposed project and any risks or contraindications for use of the EMST150 device. - The EMST150 device and instructions manual - Adherence diary
