Swallowing interventions for the treatment of dysphagia after head and neck cancer: A systematic review of behavioural strategies used to promote patient adherence to swallowing exercises

Behaviour change techniques (BCTs) can be used to improve adherence, but no review to date has described the techniques or indicated which may be more associated with improved swallowing outcomes.
