An essential clinical instrument.

The Equinosis Q with Lameness Locator® is a medical-grade diagnostic system engineered to deliver reproducible, validated results. Combining accuracy, precision, and field-based usability no other system can match.

Equinosis Q with Lameness Locator

Vertical movements of the head and pelvis are considered the most sensitive and accurate parameters for detecting lameness in the horse. Vertical acceleration most closely approximates force on the limbs (F=ma).

Inertial sensors attached directly to the horse offer superior sensitivity and accuracy on every stride, irrespective of distance from patient or observational view.

Lameness Locator has been validated in multiple peer-reviewed publications

On-board analysis in under 10 seconds for seamless integration into clinical workflow.

Regardless of lighting, weather, or environmental conditions.

Body-mounted inertial sensors continuously record many consecutive strides necessary to handle stride-to-stride variability common in horses. Equinosis Gen 7 sensors have a range of 70 to 100 meters using a Class 1 long-range wireless receiver, ideal for standard lameness evaluations. Limited Edition Gen 6 sensors can collect up to 30 minutes of data at unlimited range and automatically download it to the PC upon return. This allows for the analysis of hundreds of strides from horses exercising on a track.

Other Methods

Sensor or camera-based systems that measure limb movement only are less accurate due to the greater variability of limb movement in the horse.

With camera-based systems, accuracy diminishes as the horse moves farther away due to the decreasing size of the subject within the field of view.

Few systems marketed today have been validated with peer-reviewed research.

Data must be ported to cloud or later offloaded for analysis

Stationary systems require horses to haul in. Camera-based techniques require optimal lighting and may be hampered by dusty arenas, rain, background contrast, or other factors affecting video quality.

With line-of-sight techniques, as the horse trots toward the camera its pelvis is obscured. This limitation forces evaluators to either compromise with a reduced hindlimb stride count, a particular detriment in subtle lameness, or to prolong trotting sessions.

Designed for Veterinarians: An investment that pays for itself

The Equinosis Q with Lameness Locator® is built for equine practices. Fast, objective data improves diagnostic confidence, strengthens client trust, and opens new revenue streams. Many clinics recoup their investment within the first year.

  • More confident diagnoses using objective data
  • Improved communication with clients and veterinary colleagues
  • Portable and wireless — use indoors, outdoors, in the clinic or in the field.

What leading veterinarians are saying

  • “The Lameness Locator is easy to use, sensitive and reliable.” 

    “I have found the Lameness Locator to be especially helpful in interpreting the results of diagnostic nerve blocks in horses with subtle hind limb lameness…I more frequently identify and resolve lameness problems. The professional staff at Equinosis are extremely helpful.”
    Mark Donaldson, VMD, Dipl. ACVIM
    Equine Veterinarian, Unionville Equine Associates

  • “Equinosis has become the standard by which I assess all lameness cases“

    “After looking at lame horses for four decades, I now realize I was examining horses without as much information as I needed before I was using the Q. My clients, many of whom are discerning professionals, now rely on this technology as much as I do. After assessing more than 500 horses in the past 3 years, I have two hard and fast rules: never assess a nerve block without using the Q and never let my clients purchase a horse without the information offered by the Q.”
    Dr. Mark Baus
    Mark Baus, DVM
    Owner, Grand Prix Equine

  • “This is a remarkable device.“

    “We have three criteria before we purchase new technology. The equipment must: 1) improve equine health care, 2) improve the veterinarian’s quality of life, 3) generate revenue. The Lameness Locator does all three exceptionally well.”
