Hi Dr. O,

Regarding the following portion of this article:

"In contrast, a horse with an upper motor neuron lesion (wobbler) will have good resting muscle tone and be difficult to pull to the side in a singular movement while standing still. However, such a patient will be easily pulled to the side while walking. This demonstrates voluntary extensor weakness but the presence of intact or even hyperactive extensor reflexes in the pelvic limb."

In horses with good resting muscle tone, are there causes of voluntary extensor weakness that do not have a neurologic component? If so, what and how common are they?

Thank you!

Hello Natalie,
As a test finding not associated with any symptoms it may not have any significance at all: some horses just don't have as strong a reflexive resistance in my experience.
