A Study of Normative Data for Bone-conducted VEMP Responses (amplitude, latency, threshold, asymmetry, signal-to-noise ratio) in Patients Without Vestibular Dysfunction


About this study

The purpose of this study is to develop a set of normative data for bone-conducted VEMP responses (amplitude, latency, threshold, asymmetry, signal-to-noise ratio) in patients without vestibular dysfunction, and to assess the reliability and replicability of these responses.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria: 

  • Adult or children subjects with present and symmetrical cervical and ocular VEMPs elicited with air-conduction stimuli.  Subjects will not be excluded due to additional otologic presentation (e.g., hearing loss, tinnitus).
  • Patients who have undergone a unilateral cochlear implantation and device activation referred by our Cochlear Implant Clinic.
  • Typically-developing children without balance disorders will serve as participants for this investigation. 

Exclusion Criteria: 

  • Patients less than 6 years of age. 
  • Subjects will be excluded if they are unable to maintain muscle contraction sufficient to record responses.
  • Patients with significant orthopedic and/or neurological deficits that influence balance or mobility performance, and prevent reliable completion of the testing procedures will be excluded from the study.
  • Additional handicap that would limit the patient from being able to follow study instructions.
