Figure 5.11. The Scale Of 7 Modifiers Is Intended To Denote The Patient's Degree Of Impairment/Limitation/Restriction - biodex GAIT TRAINER 3 Application/Operation Manual

The Severity Code Modifiers are a series of impairment level ranges made up of about 20
percentage points each, where for example, "CI" would represent a status of 1-19% impairment.
Figure 5.11. The scale of 7 modifiers is intended to denote the patient's degree of
impairment/limitation/restriction.
For further reference, review the chart below to see how the Gait Trainer software calculates
Impairment Percentage. In measuring a patient's average walking speed, the software assigns
an Impairment Percentage "score" based on the patient's average walking speed during a
particular session. If an average speed 0.1 MPH, but less than 1.1, cannot be obtained, the
patient is considered to be 100% impaired. If the average walking speed is 1.1 MPH or greater,
the patient is considered to be 0% impaired.
Note: In this example, a "normal" range of 1.1 to 1.82 MPH is calculated from the age, gender,
and height data entered on the Patient Setup screen.
