You may remember that a few weeks ago we did the IMU (inertial motion units) gait analysis with Mr P, which showed he was moving evenly in front but had a right hindlimb asymmetry. There was video in which that right hind lameness was quite apparent.
We repeat this analysis every 2 weeks, and this next one was done after he had his shoes put on. It was quite different...
What we are seeing now fits a little more with his clinical diagnosis. He is moving largely symmetrically behind (anything under 8mm is considered within “normal” range in the pelvis - data on the right), and we’re now seeing a significant right forelimb asymmetry, worse in the push off or propulsion phase (data on the left).
So why were we seeing a right hindlimb but not a right forelimb lameness before?
The likely explanation relates to his feet. He was incredibly foot sore before he had shoes on, so the “evenness” in front was likely due to him being “equally sore” in both front feet, not giving us a true reading of his soundness relating to the tendon injury. Now that we’ve technically taken away the foot soreness, what we are seeing is an asymmetry purely related to the tendon injury.
Now we can hopefully more accurately monitor his response to treatment!
