Abstract

An approach to monitoring, evaluation, diagnosis, treatment or conditioning of animals such as horses does not require use of restrictive equipment such as treadmills or force plates and that can provide either or both of more or less immediate or continuous processing of data to perform the monitoring or diagnosis. One or more wireless sensors are attached to the animal, for example, to measure motion-related parameter associated with one or more parts of the animal. Sensor data is received from the sensors and processed to identify a characteristic of the motion of the animal, such as a quality of gait. The sensor data can also be used to avoid injury to the animal and/or the rider, and to verify the identity of an animal.

Claims

1. A method for determining potential performance of an animal comprising:

acquiring objective measurements from the animal, including acquiring sensor measurements sufficient for determining a quality of motion that depends at least in part on a trajectory of a limb of the animal;

acquiring measurements from other animals and storing performance attributes of the other animals;

comparing the objective measurements with criteria derived from the measurements acquired from the other animals; and

predicting potential performance based on a result of the comparison;

wherein acquiring the measurements from the other animals includes acquiring measurements from the other animals at a stage of development corresponding to that of the animal for which potential performance is to be determined, and storing the performance attributes of the other animals includes storing attributes of the other animals corresponding to a later stage of development.

2. The method of claim 1 further comprising processing the acquired objective measurements, including deriving motion-related parameters from objective measurements.

3. The method of claim 2 wherein said motion-related parameters include a parameter from the group consisting of:

stride length;

stride rate;

height and length of a foot flight arc;

alterations in foot flight;

4. The method of claim 2 wherein said processing the acquired objective measurements further includes determining the quality of motion that depends at least in part on a trajectory of a limb of the animal.

5. The method of claim 4 wherein said quality of motion includes a characteristic that depends on a degree of a defined type of motion.

6. The method of claim 4 wherein said quality of motion depends on trajectories of multiple limb segments.

7. The method of claim 6 wherein said quality of motion depends on relative motion of said limb segments.
