Study summary

This study investigates in patients whose primary complaint is either neck pain and/or a voice disorder , if there are any correlations between subjective neck and voice symptoms according to Neck Disability Index (NDI) and Voice Handicap Index (VHI). NDI and VHI questionnaire results for voice disordered patients will be retrieved from the data base of the Department of Phoniatrics and Speech Pathology, University Hospital Zurich. Neck pain patient questionnaire data will be retrieved from an ongoing study. The agreement between subjective neck handicap (NDI) and voice handicap (VHI) will be statistically analysed.
