Head and neck cancer has a negative impact in swallowing function and quality of life. Rehabilitation has proven its usefulness after radiation therapy (RT), but some studies suggest that interventions should be initiated prior to RT sessions. This study aims to evaluate the effects of prophylactic rehabilitation on swallowing and quality of life. The study pretends to establish a preventive rehabilitative program with the target of reducing RT side effects and improve patients' quality of life.
Head and neck cancer has a negative impact in swallowing function and quality of life. Although current diagnostic and therapeutic protocols try to preserve swallowing and speaking, acute or late dysphagia as well as a poor quality of life are frequent in these patients. Some studies have reported an improvement in swallowing function after an exercise based intervention following radiation therapy (RT), regardless the need of concomitant chemotherapy (RT-QT). Other studies focus the interest in the use of prophylactic exercises to prevent or minimize post-swallowing dysfunction. Patients receiving RT or RT-QT refer worsening of their quality of life, especially during the first days after treatment. One study suggests that rehabilitation prior to cancer treatment could potentially improve quality of life. However, this observation should be contrasted with a randomized study.

Early swallowing exercises and respiratory muscle training: Standard swallow therapy and instructions for training submental muscles involved in swallowing function and expiratory strength starting 2 weeks before radiotherapy Expiratory/Inspiratory training: the training load is the maximum inspiratory/expiratory load defined according to patient tolerance. This load will be equivalent to 10 maximal repetitions (RM) as 10 consecutive inspirations (x 5 sessions), three times a day. All sessions will be conducted under the supervision of an expert physiotherapist/swallowing therapist. The total duration of the training program is 6 months.
Late swallowing exercises and respiratory muscle training: Standard swallow therapy and instructions for training submental muscles involved in swallowing function and expiratory strength starting after completing radiotherapy
