Impairment Quantification

Most spine impairment measures rely on subjective feedback from patients, including VAS Questionnaires that include questions such as "rank your pain on a scale from 0-10".  Unfortunately these measures are highly variable and are confounded by many factors not related to the disorder.

The impairment measures developed in our laboratory focus on quantifying an individual's motion characteristics with devices such as the Lumbar Motion Monitor (LMM).  While wearing this device, the patient "plays a video game with their back".  Once motion characteristics are measured, they can be compared to large normative databases to determine a patient's degree of impairment given their age and gender.  This produces a percentage of normal score that can be used to help:

  • Determine the severity of a disorder
  • Monitor whether the disorder is improving over time
  • Evaluate the success of different treatments
  • Decide when it is safe for a patient to return to work
