Systematic review of adherence to swallow and trismus exercises during radiation therapy for head and neck cancer.

Understanding the barriers and facilitators for prophylactic swallowing and trismus exercises for patients undergoing radiation to the head and neck may help exercise adherence. The analysis reviews all published reports of exercise adherence with a critical appraisal following PRISMA guidelines. A total of 137 potential papers were identified; 20 studies met the inclusion criteria. The most commonly reported facilitators for swallowing and trismus exercises were regular clinician contact and online resources to reinforce instructions, set goals, and manage radiation toxicities. Social support and perceived benefit from exercises were also reported to be of help. The most common barriers to exercise were radiation toxicities, anxiety, feeling overwhelmed with information, and not understanding the reason for the exercises. Understanding facilitators and barriers to adherence is critical when designing exercise interventions for patients undergoing radiation for head and neck cancer. [ABSTRACT FROM AUTHOR]
