Motion measurements/exertion measurements in the dog

Goal of exertion measurements

  1. Many dogs show a lameness or movement disorder just during or after exertion. The dog can thus be exposed to a physical strain, for example to 45 minutes of cycling. In this diagnostic procedure, the patient is measured kinetically before and after the exertion, which allows the detection of exertion-induced movement disturbances. This cannot be determined with an image based diagnosis (MRI, CT, ultrasound or scintigraphy).
  2. The physical conditioning can be monitored perfectly this way. For example, we can measure the power of the hindquarters before and after a performance and quantify the conditioning. This can be very important for the training of sled dogs, racing dogs (greyhounds) and for military and police, ie. for young dogs during physical conditioning / training.
  3. During rehabilitation, the conditioning can be quantified as well. This is especially important for dogs after back surgery. To give an example, a service dog of the SBB was in my office recently.
  4. Selection of dogs that have to fulfil a certain role can now be made more objectively (for example with guide dogs for the blind).


As you can see from the list of goals above, the exertion measurement is an important aspect from a diagnostic point of view. Kinetic and kinematic parameters can provide helpful information, especially when image-diagnostic indications of motion impairment are missing.


Even after image-diagnostic modalities such as MRI or CT, with very many dogs there are still no indications to explain the motion disorder. In these cases, it remains open why the dog is limping, and a bad feeling remains. One must acknowledge that an image diagnosis cannot display movement. This is only possible with kinetic or kinematic parameters. To date, these possibilities in the dog's medical treatment have been missing. With our development we can now fill this gap. Finally, there is a possibility to carry out performance assessments with dogs, as it has been customary, everyday work in the treatment of horses for a long time.  


A real life example: we have a patient, 2 years old, training to be a working dog. She shows recurring lameness in the rear right limb. Hip and knee x-rays do not give any pathological indications. The suspicion of growth disturbances in the end plates of the vertebral bodies was assumed. When the dog was introduced to me, she was on heat and showed additional problems of an infection as well as an endocrinological disturbance. After further clarifications regarding the hormonal system and MRI, a clear diagnosis was still not available. The dog was then slowly conditioned and trained via exertion-movement diagnostics. After two months of controlled conditioning, the dog is free of lameness and can now continue with her training.










Please note the following:

The red dots are the values before exertion

The yellow dots are the values after 1.5 hours of exertion


AL: front left   AR: front right
PL: rear left   PR: rear right
BF: spine front   BP: spine rear






Objective of exertion measurements

  1. Controlled athletic and conditiong development
  2. Targeted rehabilitation, objective and quantifiable
  3. Follow-up check and the adaptation of therapy / rehabilitation


Exertion measurements are a clear advantage of the kinetic / kinematics, which can not be fulfilled by image diagnosis such as x-ray, CT, MRI, since the movement cannot be recorded or measured. This method is also very suitable after back surgery or after an operation of the cruciate ligaments, if despite the operation, lameness or other symptoms still persist.
