Assessing the Impact of Novafon Local Vibration Voice Therapy on Voice Disorders: A Comprehensive Review

Abstract

   INTRODUCTION: Voice disorders, or dysphonia, are prevalent conditions impacting individuals' lives. Novafon Local Vibration Voice Therapy (NLVVT) is an emerging intervention using vibrational stimulation for voice rehabilitation. This systematic review evaluates NLVVT's efficacy in improving voice quality, neuromuscular control, and self-reported outcomes in voice disorders.  METHODS: Studies were identified through comprehensive searches in electronic databases, including PubMed, Scopus, and Google Scholar, using predetermined search terms related to Novafon Local Vibration Voice Therapy (NLVVT) and voice disorders. The eligibility criteria, guided by the Population, Concept, and Context (PCC) framework, encompassed studies investigating NLVVT interventions in individuals with voice disorders.  RESULTS: Four studies met eligibility criteria, demonstrating significant improvements in voice quality, vocal range, neuromuscular control, and self-reported outcomes following NLVVT. This included enhanced Voice Range Profile boundaries, consistent falsetto register, and reduced Dysphonia Severity Index scores.  CONCLUSION: NLVVT shows promise as an effective intervention for voice disorders. It offers potential benefits in enhancing vocal function and quality, thus improving patients' lives. Further research and clinical application are warranted to establish NLVVT's place in voice rehabilitation.
