ETB-Pegasus Cannon Angle Analysis

What is the Cannon Angle Analysis System?
The system is a software upgrade to the ETB-Pegasus Limb Phasing System, adding considerable in depth analysis of the sagittal and coronal planes of movement for each of the four cannon bones.

Carrying out a trial
As with the ETB-Pegasus Limb Phasing System, brushing boots with sensors are used. The horse stands still for 5 seconds to calibrate the sensors and then the trial begins. The trial can be a simple trot up in hand, exercise on a treadmill, ridden and/or un-ridden at walk and trot on any surface.

Analysing data
The sensor data is processed and all the parameters automatically presented, simply by connecting the sensors to the notebook and selecting “Analyse”.  Data is presented in three forms:

A Summary of the findings for the provided example.
This horse had an uneven stride in trot in the fore limb cannon movement.  When looking at the right fore limb there is predominately movement in the sagittal plane (blue line) and little movement in the coronal plane (green line is nearly horizontal), which is correct for a normal gait pattern.  The left fore limb however has less sagittal plane movement and a lot of coronal plane movement (it is not horizontal at 0).  This horse had a tendon injury on the left fore and accommodated this by swinging the limb out rather than under the body.  The left and right hind have similar profiles, total sagittal plane angle and minimal movement in the coronal plane, indicating that the hind limb movement is symmetric.
