Definitions

  • the present invention relates to devices, methods and systems for the early detection of various diseases and conditions in an ungulate mammal, such as a horse, as well as for continuous monitoring the mammal's health condition.
  • Horses are well adapted to running and labor. However, their unique physical properties that contribute to their abilities are also the reason for many of the horse's diseases and harmful conditions-especially those involving their legs and feet. Laminitis, Navicular Disease, Quarter cracks, tendonitis, and infections, such as Thrush and Quiltor as well as colic, are examples of such conditions and other diseases. These conditions and disease can also affect other ungulate mammals, such as cattle, camels, etc.
  • Laminitis is an example of a serious harmful condition that affects horses of all breeds, ages and genders throughout the world. It is a common, painful, and potentially disastrous condition of the horse's foot.
  • the disease affects the tissues that attach the hoof wall to the coffin bone within the hoof capsule.
  • Laminitis is a failure of the attachment between the distal phalanx (coffin bone) and the inner hoof wall, caused by inflammation of the laminae: The lamellae of the inner hoof wall attaches the distal phalanx from the inner surface of the hoof capsule, and when this connection fails, the horse suffer from laminitis.
  • Laminitis is a potentially fatal disease due to the persistence and severity of pain, and the structural damage that occurs in affected ungulate mammals such as horses. Horses that survive an acute episode of laminitis frequently require long-term management and are predisposed to recurrent episodes.
  • the coffin bone which is the main bone of the foot, provides the horse's foot the required rigidity for bearing the horse's weight. It is actually suspended in the hoof, attached by a Velcro-like arrangement of specialized structures, called laminae, to the inside of the hoofs wall. Thus, the laminae hold the hoof wall onto the coffin bone.
  • the laminar dermal region also (i) contains sensory nerves that inform the horse about the position of its hoof, (ii) involved in thermo-regulation, and (iii) contains blood vessels that nourish the hoof and allow its growth.
  • Blood supply to the equine foot is unusual: in addition to the normal arteries- capillaries-veins circulation, the equine foot also has arteriovenous shunts, which allow the arterial blood to go directly to the veins, bypassing the capillaries. When these shunts are open, little or no blood is going to the tissues. The shunts are thought to protect the capillaries from unduly high blood pressure.
  • Laminitis usually develops as a result of a variety of seemingly unrelated pathological events occurring elsewhere in the horse's body. This makes the identification of laminitis extremely hard, if not impossible.
  • Laminitis is divided into four phases: the developmental phase; the acute phase; the sub-acute phase; and the chronic phase. Treatment and prognosis of laminitis is depended on the phase of the disease, wherein animals that are treated at an earlier stage often present better prognosis. Thus, it is desirable to detect laminitis as early as possible. Accordingly, a need exists for means to easily monitoring the early occurrence of laminitis in order to avoid irreversible damage and improve prognosis.
  • Laminitis starts in a prodromal or developmental phase, when the pathological lamellar changes start, and lasts for about 24 to 48 hours, in which the first clinical signs might be detected.
  • the acute phase of laminitis begins together with the onset of clinical signs and starts anywhere from 24 to 72 hours after the initial damage to the basement membrane. This phase is expressed by visible clinical signs, such as increased hoof temperature, increased digital pulse and lameness.
  • the acute phase ends with the displacement of the distal phalanx and/or following 72 hours of pain. Then begins the chronic phase of laminitis.
  • Acute laminitis e.g. in horses and cows, is characterized by some or all of the following signs: (i) turning in circles or reluctance to move; (ii) heat in the feet; (iii) increased digital pulse in the feet; (iv) pain in the toe region when pressure is applied with hoof testers; (v) reluctant or hesitant gait ("walking on eggshells”); (vi) a "sawhorse stance" (front feet stretched out in front to alleviate pressure on the foot); and (vii) systemic changes: anorexia, anxiety, increased respiration and pulse rates.
  • laminitis After 72 hours of lameness or after the rotation and/or sinking of the coffin bone due to the separation of the laminae at the front of the foot, laminitis is considered as "chronic laminitis".
  • Chronic laminitis is characterized by the following signs: (i) rings in hoof wall that become wider as they are followed from toe to heel; (ii) bruised soles or "stone bruises”; (iii) widened white line ("seedy toe") with blood pockets and/or abscesses; (iv) dropped soles or flat feet; (v) thick, "cresty” neck; and (vi) dished hooves (due to unequal hoof growth rates).
  • Acute laminitis constitutes a medical emergency since phalangeal displacement might occur rapidly. Despite prompt therapy, the prognosis is guarded until recovery is complete and it is evident that the hoof architecture is not altered.
  • non-inflammatory agents such as NSAID, lidocaine and dimethyl sulfoxide, are usually administered.
  • Laminitis therapy includes cryotherapy (mainly at early stages), medications (for pain and infections), and surgery.
  • recovery from laminitis is unpredictable, and prognosis is directly proportional to the extent of displacement of the distal phalanx and the resultant lamellar pathology that occurs.
  • Prognosis is also highly affected by early identification and treatment. Although few horses return to normal athletic soundness after chronic laminitis, most make only partial recovery and often suffer from intermitted lameness or recurrent episodes of foot pain.

  • Acute laminitis constitutes a medical emergency because phalangeal displacement can occur rapidly. Despite prompt therapy, the prognosis is guarded until recovery is complete and it is evident that the hoof architecture is not altered. Most animals should be administered NSAID and other non-inflammatory agents such as lidocaine and dimethyl sulfoxide to reduce the inflammatory process present in the prodromal and acute phases of laminitis. Other options for analgesia include detomidine, butorphanol, morphine, or a constant-rate infusion of a "cocktail" of sedatives and analgesics. In a horse at risk or in the early stages of laminitis, a cryotherapy, where the hoof wall temperature is reduced to a less than 5°C throughout a 48-hour period has been shown to be very effective.
  • the feet should be padded with a soft, resilient substance. Decreasing padding (or beveling the pad) in the region dorsal to the apex of the frog (a V-shaped structure extending forwards across about two-thirds of the sole) decreases the stress on the dorsal laminae. Shoeing horses with laminitis is usually not a good option until about 3 weeks after the onset of laminitis, when the laminar structure may be stabilizing.
  • Surgical treatment options include deep digital flexor tenotomy, to neutralize the pull of the deep digital flexor tendon, and dorsal hoof wall resections.
  • Deep digital flexor tenotomy is most commonly performed in cases of chronic rotation that do not respond to the above shoeing techniques; it should always be accompanied by aggressive de-rotation via rasping of the caudal foot.
  • the farrier and veterinarian must address subluxation of the coffin joint subsequent to surgery in the majority of cases.
  • only a partial hoof wall resection is performed due to the severe digital instability caused by removing the entire dorsal wall.
  • cryotherapy As stated above, the most common and straightforward therapy of laminitis is by cryotherapy. There is a multitude of commercially available cryotherapy solutions available today: (i) simple immersion in ice water buckets / tubs; (ii) ice packs; (iii) cold wraps; (iv) ice boots; (v) bags filled with ice and water; (vi) a combination of pressure and cold applicators such as the Game Ready equine product line.

  • Possible algorithms according to the present invention upon detection of any anomaly or possible damage to the animal's include, but are not limited to, an alert following a sharp temperature elevation or following a temperature elevation for a long period of time compared to the normal elevations measured during the baseline measurements.
  • Another possible example is an alert following a change in movement, such as in lameness, as indicated by an accelerometer or other sensors.
  • data from all or any combination of the different sensors located onto the animal's body may be compared to provide additional verification.

  • baseline parameters may be determined, e.g. for resting, for training, for competing, etc.
  • the system can be calibrated to send alerts according to a specific baseline. Accordingly, when the animal is competing, in which case the overall measured parameters are naturally elevated, no alert will be sent due to using the "resting baseline”. Only if the measured parameters exceed those of the "competing baseline" an alert will be sent.
  • the alert is sent by any means selected by the user, such as by email, phone call, and text message, or any combination thereof.
