How It Works

Objective Data. Seamless Workflow. Confident Decisions.

The Equinosis Q provides objective, accurate measurements in seconds — empowering you to evaluate with confidence and communicate with clarity.

How It Works

Research-Validated Precision. Practice-Proven Performance.

Accurate

When a horse shifts load from a limb, the result can be measured by changes in acceleration of the horse’s head and pelvis when trotting. Changes in vertical movement of the head and pelvis are directly related to changes in force on the limbs (F=ma). Using scientifically validated proprietary algorithms that remove the inherent “noise” from acceleration, The Q measures asymmetry with sub-millimeter accuracy.

Sensitive

With 10 times more sensitivity than the human eye, and sophisticated algorithms based on decades of veterinary research, the Q quantifies motion asymmetries directly associated with decreased weight bearing.

The Power of Objective Data Without Changing the Way You Work

Step 1: Attach the Sensors

Lightweight (<21 grams) wireless sensors are secured to the poll, midline pelvis and RF pastern in under 60 seconds. They’re comfortable for the horse and do not interfere with movement.

Step 2: Record Trial

Observe the horse as you would for your normal evaluation – in a straight line, lunging, following flexion tests – while simultaneously collecting data.

Step 3: Review Analysis

Data is collected and transmitted to the hand held PC in real-time and immediately ready for analysis.

Our software instantly analyzes thousands of data points. Most analyses are reported in as little as 5 seconds. Results are presented in clear, objective metrics that show: affected limb(s), degree of asymmetry, and timing of asymmetry in the stride cycle. Additional diagnostic insights include effect of flexion tests and diagnostic blocks, change over time, and probability of the primary limb in a multiple limb lameness presentation.

Step 4: Share Results

Reports can be exported as PDFs or JPEGs and shared directly with horse owners. Stride plots provide visual representations of the asymmetries and side-by-side comparisons help clients understand what is measured, how lameness changes with block or treatment and provide objective support to your clinical recommendations.

Frequently Asked Questions

Subtle changes in symmetry of movement can be missed due to the limited temporal and spatial resolution of the human eye. Equinosis Q inertial sensors sample 10x faster (200Hz) than the human eye, allowing for the detection and measurement of very subtle asymmetries in head and pelvic movement. Proprietary software analysis, with decades of validation behind it, provides results with submillimeter accuracy.

Multiple limb involvement, including compensatory and secondary lameness, can complicate what is observed. The distribution of lameness (fore and hind, ipsilateral or contralateral) and the timing of hindlimb lameness (impact, pushoff or both) can be predictive of the primarily lame limb. The software evaluates for these known & studied compensatory lameness patterns and may suggest a primary limb when both a fore and hindlimb lameness is measured.

Objective quantification of change from diagnostic analgesia enables the veterinarian to more precisely evaluate and document improvement. Sequential evaluations provide objective information on response to therapies, improvement during a rehabilitation process, or monitoring a horse’s baseline through a competition season. Objective measures provide more accurate assessments within an exam, over serial exams, and between veterinarians evaluating the same horse. The added information also facilitates communication with your client.

The Q is designed to provide real-time results as the clinician is working through their moving examination, without slowing them down. Sensors can be applied in as little as 60 seconds. View a complete instrumentation.

Two straight line collections should be performed to confirm measurements are stable (unstable lameness is not uncommon and can confound the evaluation both objectively and subjectively). Data collections and analyses can be conducted every time the clinician trots the horse during the exam (e.g. straight line, lunge, flexion, post blocks…). Data collection and analysis is in real time and the results are reported in as little as 5 seconds for each trial, no internet is required”.

The analysis informs the veterinarian of asymmetries in vertical head and pelvic positions between right and left halves of stride associated with equine lameness. It indicates which limb or limbs are exhibiting decreased load, the amplitude of head (forelimb) and pelvis (hindlimb) asymmetry, and lastly, the timing of the lameness. For instance, is it a lameness that is primarily “felt” by the horse at impact, mid-stance, or push off? The analysis is supplied in a single page report, providing an overall qualitative assessment in a graphical stride plot diagram, as well as mean and standard deviation calculations of head and pelvic movement asymmetry over the course of the collection. A limb-by-limb auto-interpretation of the data is also available to the clinician.

Additional comparison report functionality and clinical interpretation guidance is available for lunging, flexions, blocking, rechecks, and ridden evaluations.

Q reference ranges were determined experimentally using a relatively narrowly-controlled environment, in a heterogeneous sample consisting of horses of many ages, sizes, breeds, and use, with subjective evaluations for lameness ranging from moderate (grade 3 on the AAEP scale) to no lameness (grade 0 on the AAEP scale), taking care to obtain data with low stride-to-stride and trial-to-trial variability. The reference ranges were derived from the 95% confidence intervals of the inertial sensor measures predicted when the mean subjective AAEP score from at least three veterinary evaluations was 0. However, lameness, like many clinical signs, is not binary. Horses may have natural asymmetry that is not attributable to pathology or a painful condition. It is important to note that these reference ranges are not meant to be considered as the demarcation between sound and unsound.

Horse Owners: Confidence in Every Step

The Equinosis Q provides your veterinarian objective data that complements their subjective observations and physical examination.

Small, lightweight sensors are placed on your horse. Instrumentation takes about a minute. The sensors are safe, comfortable, and do not interfere with movement.

Step 1: Quick Start

Step 2: Real-Time Data Collection

Data is collected while your veterinarian observes your horse as he or she normally would. This may involve trotting the horse on the straight line, lunging, and after flexion tests and blocks. The Q can also be used when the horse is ridden.

Step 3: Clear Results

Stride plots provide a visual representation of which limbs the horse is unloading, the amplitude of asymmetry and where in the stride cycle the unloading is occurring (at impact or pushoff). Your veterinarian will correlate the information to their clinical observations and use it to guide next steps.

Step 4: Track Improvement & Follow Progress

Following a diagnosis, the Q can be used to monitor your horse after treatment or through rehabilitation. The Q can also be used during periods of wellness to establish if your horse as a “usual way of going”. This is helpful to compare when something feels different in your horse.
