Systematic review of biofeedback interventions to improve swallowing


  • Although high quality evidence for the use of biofeedback to improve swallowing in people with Parkinson’s disease (PD) and dysphagia is lacking, the technique appears promising and warrants further research.

Why this matters

  • Biofeedback is a technique which can be used to improve a patients’ awareness and control over motor tasks such as swallowing, and therefore can be useful in rehabilitation for people with dysphagia.

  • Visual biofeedback approaches might be particularly well-suited to rehabilitating dysphagia in people with PD, as it can assist patients to integrate different movement components.

  • However, evidence for the effectiveness of biofeedback approaches in people with PD and dysphagia remains unclear.
