title: Standing balance tests for screening people with vestibular impairments.
abstract: OBJECTIVE
  To improve the test standards for a version of the Romberg test and to determine whether measuring kinematic variables improved its utility for screening.
  
  
  METHODS
  Healthy controls and patients with benign paroxysmal positional vertigo, postoperative acoustic neuroma resection, and chronic peripheral unilateral weakness were compared.
  
  
  METHODS
  Subjects wore Bluetooth-enabled inertial motion units while standing on the floor or medium-density, compliant foam, with eyes open or closed, with head still or moving in pitch or yaw. Dependent measures were time to perform each test condition, number of head movements made, and kinematic variables.
  
  
  RESULTS
  Patients and controls did not differ significantly with eyes open or with eyes closed while on the floor. With eyes closed, on foam, some significant differences were found between patients and controls, especially for subjects older than 59 years. Head movement conditions were more challenging than with the head still. Significantly fewer patients than controls could make enough head movements to obtain kinematic measures. Kinematics indicated that lateral balance control is significantly reduced in these patients compared to controls. Receiver operator characteristics and sensitivity/specificity analyses showed moderately good differences with older subjects.
  
  
  CONCLUSIONS
  Tests on foam with eyes closed, with head still or moving, may be useful as part of a screening battery for vestibular impairments, especially for older people.
