Balance System SD (with v4.X software) 109
Normative Data
The new Biodex Balance device comes equipped with several sets of normative data. Normative
data for balance are typically noted as the average and standard deviation numbers derived
from various scores in previous controlled studies. These data sets are separated into different
population groups in order to give relevant norms for the population being tested.
It is highly recommended that when tests are conducted the correct normative data set
associated with the population and protocol is used. Having the relevant normative data
enables the vetting of baseline testing. Additionally, if a patient does not have a baseline test,
the normative data becomes the baseline for that patient.
m-CTSIB Test
For the m-CTSIB test, there are four normative data sets available:
● For the Aggregate General Population, ages 13 – 85, data on CTSIB reliability and
predictive score is the combined data of the three other data sets listed below.
● The Male and Female, ages 13 – 18, 20 second trial normative data was collected from a
population of student athletes, male and female, ages 13 – 18. The data was collected
by Carolinas Medical Center, Charlotte, NC, Department of Sports Medicine & Special
Events, at four special events during the 2011 summer. Data analysis was provided by
Raymond F. McKenna, PT, PhD, Clinical Associate Professor, Stony Brook University
School of Health Technology and Management, Department of Physical Therapy State
University of New York.
● The 65 – 84 Male and Female Independent normative data was collected from two
populations of older adults, male and female, ages 65 – 84. The data was collected by
Georgia Southern University in Statesboro, GA, and Adelphi University in Garden City,
NY.
● The 17 – 23 Male and Female NCAA Baseline normative data was collected from a
population of athletes, male and female, ages 17 – 23. The data was collected by David
Bica, DO and Anthony S. Kulas PhD, ATC, LAT, Department of Sports Medicine, the Brody
School of Medicine, East Carolina University, Greenville, NC.
