Automated Interpretation and Degree of Evidence (AIDE)Interpretation assistance is offered at the bottom of the report. The strength of evidence reported is based on whether the TDH/VS, Diff Max pelvis or Diff Min pelvis is outside of the reference range for that measure and the stride to stride variability (SD). Indications of severity are based on a general range of amplitude of lameness, with levels increasing from “very mild”, “mild”, “mild/moderate”, “moderate”, and “moderate/severe”. The timing of the asymmetry is also noted in the AIDE. |
Compensatory Lameness PatternsLaw of Sides Ipsilateral suggests 1º hind limb lameness - THIS IS TRUE!!!!! WATCH OUT
Contralateral suggests 1º forelimb lameness - This is partly true… Most Common
Less Common
|
Diff Max Headthe difference in maximum head height that occurs before RF weight bearing compared to before LF weight bearing. Ref range: -6.0 to +6.0 mm
|
Diff Max Pelvisthe difference in maximum pelvis height that occurs before RH weight bearing compared to before LH weight bearing. Ref range: -3.0 to +3.0 mm
|
Diff Min Headthe difference in minimum head height that occurs during RF mid stance compared to during LF mid stance. Ref range: -6.0 to +6.0 mm
|
Diff Min Pelvisthe difference in minimum pelvis height that occurs during RH mid stance compared to during LH mid stance.Ref range: -3.0 to +3.0 mm

Hard SurfaceIf the foot does not create a depression or a divot in the ground, the surface should be considered hard. Hard preset surfaces = asphalt, concrete, packed dirt, gravel/stone, wood, frozen, treadmill, hard synthetic, hard (generic). |
Head SensorThe head sensor device contains an accelerometer that tracks vertical head acceleration. |
Indications of SeverityIndications of severity are based on a general range of amplitude of lameness, with levels increasing from “very mild”, “mild”, “mild/moderate”, “moderate”, and “moderate/severe”.
**The veterinarian should keep in mind that the severities are a range, and should not be used to compare two trials for consistency of amplitude (such as in establishing a stable baseline between two trials) or to assess change in amplitude (such as before and after a block, or change over time). |
Lameness Metricsquantitative data from the collected trial. Calculated lameness metrics include 1) mean values of Diff Max head, Diff Min head, Diff Max pelvis and Diff Min pelvis; 2) standard deviations for each respective mean Diff Max and Diff Min; 3) Total Diff Head (mean vector sum) of the forelimb data; and 4) The Q Score for both forelimb and hind limb data. |
