During the enrollment period of eight weeks, 160 consecutive subjects were initially recruited by the laboratory technicians who performed the vestibular function testing. The research study was approved by the University of ************** Institutional Review Board (PRO11030342). Approximately half of the sample had evidence of peripheral vestibular dysfunction. Clinical characteristics of the sample are documented in Table 1. Potential participants were excluded from the study if they were unable to ambulate or could not read English. There were a total of 45 participants who completed the study (29 females, 16 males), with a mean age of 56 y (SD 15 y, range 18–79 y). Individuals were enrolled who were seeking care from a neurotologist because of symptoms of vertigo, dizziness, and unsteadiness. The purpose of this study was to assess the responsiveness of four self-report measures that assess different abilities related to impairment, function, and activities and participation of people with vestibular disorders. It is critical to determine whether these self-report measures detect change over time in order to successfully use the questionnaires in practice. Despite an instrument having acceptable validity and reliability, it may not be responsive to change. 8 The responsiveness of many self-report measures commonly used with individuals who have vertigo, dizziness, and unsteadiness has not been assessed. 7, 8 A responsive instrument will help clinicians, patients, and other interested parties accurately assess improvement in a patient’s condition when the patient reports improvement, and deterioration in a patient’s condition when the patient reports worsening. Responsiveness is the ability of an instrument to accurately detect meaningful change over time. In the clinical setting, outcome measures are a critical tool in quantifying the limitations of a patient and developing a plan of care to help patient’s better reach their goals. In order to better understand these debilitating issues, several instruments have been developed to attempt to assess the patient’s concerns. 6 These individuals also avoid participating in their community for the same reasons. Simple, everyday tasks such as climbing stairs, going to the store, and driving are commonly avoided in this population because of the fear associated with falling or an increase in symptoms. 5 Vestibular disorders limit participation and restrict activities in people of all ages. 4 People with dizziness also have an associated fear of falling because of their symptoms. 3 There is also evidence that individuals who have a vestibular disorder have an increased incidence of falls. 1, 2 The impact of vertigo, dizziness, and unsteadiness on an individual’s ability to function is substantial, resulting in severe limitations in everyday activities and an overall decrease in quality of life. ![]() All rights reserved.Dizziness is one of the most common reasons for a physician or emergency room visit in the United States. Moreover, the patients with BPPV who had the positive values of items 7 and 23 may provide physicians with clue to look for HCB. Conclusion: The DHI scores of BPPV were higher for HCB than PCB. Significant difference with p-value <0.001 was the combination of item 7 and 23. Significant difference in the items with p-value <0.01 were item 7 (function, difficulty reading) and 23 (emotion, depression). The p-values of the differences in the average functional items, emotional items, and physical items between both groups were 0.028, 0.061, and 0.026, respectively. The average DHI scores for PCB and HCB were 38.91☒2.21 and 48.12☑9.55 (p-value 0.022), respectively. Results: Sixty-four patients had PCB, 50 had HCB during the study period between April 2015 and March 2017. All cases were treated with proper maneuver and followed-up until satisfactory clinical improvements and absence of positional induced nystagmus. All the patients completed DHI forms at their first visit prior to consultation and at the last visit. The subjects were patients diagnosed with PCB or HCB using the Dix-Hallpike test and the supine roll test. The setting was a tertiary otolaryngology practice. Materials and Methods: A prospective cross-sectional study, the study subjects were patients presented at the otolaryngological clinic at HRH Princess Maha Chakri Sirindhorn Medical Center, Srinakharinwirot University, Thailand. ![]() Objective: To identify the Dizziness Handicap Inventory scores and items that can be differentiated in benign paroxysmal positional vertigo patients between posterior canal BPPV and horizontal canal BPPV.
