Diagnostic Blocks: Evaluating with Objective Data

Diagnostic Blocks: Evaluating with Objective Data

By Laurie Tyrrell-Schroeder Laurie Tyrrell-Schroeder, DVM | Updated on | Block AIDE, Data Interpretation, Diagnostic Blocks, LT Schroeder, OES Members Only

Diagnostic analgesia is an important part of the lameness evaluation, and, arguably, evaluating the effects of blocks is one of the greatest benefits of using objective measurement. Using objective measurement allows more accurate assessment of improvement, and prevents human bias from influencing interpretation.  The Lameness Locator software includes interpretive assistance algorithms (known as the part of the AIDE) that calculate percent improvement from a particular block, as well as a change in timing in forelimb lameness. Before explaining how the blocking algorithms work, let’s first review some important considerations and protocols one should follow as part of the...

FAQ: Why does the Trial AIDE that evaluates for compensatory lameness patterns suggest a primary lameness in some trials but not others when the patterns of asymmetry are the same?

FAQ: Why does the Trial AIDE that evaluates for compensatory lameness patterns suggest a primary lameness in some trials but not others when the patterns of asymmetry are the same?

By Laurie Tyrrell-Schroeder Laurie Tyrrell-Schroeder, DVM | Updated on | Compensatory Lameness, Data Interpretation, Law of Sides, LT Schroeder, Multiple Limb Lameness

The multiple limb algorithms that are part of straight line AIDE statements and evaluate for known compensatory lameness are conservative in nature – meaning the algorithm leans toward not suggesting a primary limb unless there is a high degree of evidence. The first criteria for suggesting a primary limb is the presence of a known compensatory pattern. In Figure 1, a forelimb lameness with an opposite hind limb push off lameness is a known compensatory pattern for a primary forelimb lameness.  The suggestion of primary forelimb is offered in the first trial but not the second. Why is...
