The purpose of this research was to determine the test-retest reliability of the Numeric Dizziness Scale (NDS). The Numeric Dizziness Scale is a 0-10 numeric subjective individual rating scale designed to quantify dizziness intensity throughout the rehabilitation process in individuals with dizziness. Twenty-six individuals with complaints of dizziness performed 2 administrations of each of the measures within a single physical therapy session. Each participant completed questionnaires in the following order: NDS (administration 1), four additional distractor 0-10 scales (balance, pain, fatigue, and ability to complete daily activities), followed by a second NDS (administration 2) 15 minutes after the first administration. In order to assess test-retest reliability of the measure intra-class correlation coefficients (ICC 2,1) were calculated. NDS current, best and worst measures demonstrated good to excellent test-retest reliability (ICC 2,1= 0.68-0.93). The ability to reliably quantify dizziness is essential to the successful evaluation and intervention in individuals with complaints of dizziness. The NDS is a reliable tool that can be used in the clinic to quantify dizziness.
