NCT ID: NCT01483937

Last Updated: 2014-06-27

Results Overview

Sensory Organization Test (SOT) is a standing balance test that measures the subject's ability to control postural sway under vestibular, visual, and somatosensory conflict. Score ranges from 0 to 100 with higher score indicating better control of postural sway.

Functional Gait Assessment is a 10-item gait assessment based on the Dynamic Gait Index. Requirements: A marked 20 foot walkway that is marked with a 12 inch width. Scoring: a four-point ordinal scale, ranging from 0-3 where "0" indicates the lowest level of function and "3" the highest level of function. Total Score = 30 with higher score indicating safer ambulation with lower risk of falling. Criterion Validity: "Authors support a cut off score of 23/30 for independent safe ambulation". Interpretation: 1) 0-19 is predictive of falls in the elderly. 2) 20-22 indicates likelihood of unexplained fall in community-dwelling, older adults, and predictive of likelihood of falling in patients with vestibular disorders. 3\) 23-30 = safe ambulators

A fall is an unintentional change in position causing an individual to land at a lower level, on an object, the floor, the ground or other surface with or without injury. This includes: slips, trips, falling into other people, being lowered, loss of balance, and legs giving way. (Exclude sudden onset of paralysis, epileptic seizure, or overwhelming external force.)

Berg Balance Scale Description: 14-item scale designed to measure balance of the older adult in a clinical setting, and measures mobility related to activities of daily living. Description: This 14-item performance-based instrument is intended for individuals with some degree of balance impairment. Scoring: A five-point ordinal scale, ranging from 0-4. "0" indicates the lowest level of function and "4" the highest level of function. Total Score = 56 with higher score indicting safer ambulation with lower risk of falling. Criterion Validity: "Authors support a cut off score of 45/56 for independent safe ambulation". Interpretation: 41-56 = low fall risk 21-40 = medium fall risk 0 -20 = high fall risk Riddle and Stratford, 1999, examined 45/56 cutoff validity and concluded: * Sensitivity = 64% (Correctly predicts fallers) * Specificity = 90% (Correctly predicts non-fallers)

Vestibular Rehabilitation Benefit Questionnaire asks the patient to self-rate disability as it affects their quality of life. Scale goes from zero, no disability, to 100 or maximal disability. The Total Benefit includes two subsets: 1) dizziness symptoms, and 2) quality of life.

Head Shake Sensory Organization Test (HS-SOT) HS-SOT instructs the patient to static stand shoulder width apart with eyes closed and uses the SOT Condition 5 sway surface protocol while shaking the head horizontally 120 degrees per second. This protocol is safe for patients when they have normalized all SOT scores. Because study subjects were reaching SOT normalization after Post Test 2, the data collected was scant and not suitable for analysis.
