EquiMoves system

How it works

In order to capture motion data, wireless inertial sensors are attached to the legs, the withers, the sacrum and the head of the horse.

The sensor data is streamed to a gateway connected to the computer. The EquiMoves motion processing software computes the relevant parameters and analyzes the horse’s gait for lameness and performance assessment.

Placing sensors is a completely non-invasive procedure. They do not disturb the normal movement pattern of the horse.

EquiMoves is very easy to use

  • You can use the system wirelessly.
  • You can start or stop measurements anytime during the normal procedure of the lameness exam.
  • You can evaluate the horses in hand, ridden or driven.
  • The workflow is designed to interfere as little as possible with the clinical lameness exam.
Step by step guide

Sensor Installation & Measurement Process

Step 1

Connecting the gateway

Connect the gateway to the laptop using a USB-cable. The power light of the gateway turns blue. In the “Start measurement” screen the gateway connection status changes from to .

Step 2

Turning on the sensors

Turn the sensors on by pressing the power button. The blue LED of the power button of each sensor starts blinking. Enter the application. In the “Start measurement” screen, check that the sensors are connected to the gateway and the status icon is .

The sensors themselves also show that they are connected: the blue LED of the power button blinks twice. Make sure the sensors have enough battery. A green color of the battery status indicator (e.g. 85%) is ideal for a lameness examination. An orange color (e.g. 20%) is also in principle sufficient for an examination. The red color (e.g. 5%) signifies that the battery should be charged before the test.

Step 3

Attaching the withers sensor

Fix the withers sensor to the girth with the power button pointing caudal. Attach the girth to the horse. Check if the withers sensor is on the mid-line of the horse.

Step 4

Attaching the head sensor

Attach the head sensor to the headpiece with the power button pointing caudal. Put the headpiece on the horse. Use a bridle to tightly secure the head sensor and to make sure it does not move during the examination.

Step 5

Attaching the sacrum sensor

Stick a few centimeters of double sided adhesive tape on the sacrum sensor. Locate the tuber sacrale of the horse. Fix the sensor to the skin between the left and right tuber sacrale with the power button pointing caudal.

Step 6

Attaching the leg sensors

Attach the brushing boots to the horse. Be careful, as the horse may kick! Put the sensors in their holders with the power buttons facing up and the Inertia logo facing laterally. Place the sensor holders on the lateral side of the brushing boots. Check if the sensor holders are aligned with the cannon bone and on the mid-line of the leg.

Step 7

Check connectivity

Lead the horse to the start location of the examination, as close as possible the gateway. Check that all sensors are still connected to the gateway. Place the gateway higher up from the ground and try to maintain a line of sight between the gateway and the horse.

Step 8

Starting the lameness examination

Press the “Start measurement” button. Let the horse stand still for 5 seconds. Then start the examination.

Step 9

Finalizing the lameness examination

Guide the horse back close to the gateway. Let the horse stand still for 5 seconds. Check again that all sensors are connected to the gateway. If not, wait for all of them to reconnect. After that, press the “Stop measurement” button to end the measurement. Wait until the data is synchronized. This can take up to a few minutes.

Step 10

Exporting the data

Wait for the data to be processed. This can take up to a few minutes. Check the results of the lameness examination. You can choose to make a report for the owner.
