ETB-Pegasus Hock Angle Analysis
What is the Hock Angle Analysis System?
The system is a software upgrade to the ETB-Pegasus Limb Phasing and Cannon Angle systems, adding considerable in depth analysis of the hock angle movement.
Carrying out a trial
The brushing boots and gaskin straps containing sensors are placed on the horse’s hind limbs. The horse stands still for 5 seconds to calibrate the sensors and then exercise begins.
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 example shows that the total flexion angle on the left and right hock joint was the same and the variation was minimal. The profile of the left and right hock angle was also very similar. In summary, the hock movement at trot was symmetric. There were no apparent issues with this horse.
