Definitions

  • This invention relates to an equine compression sock.
  • Therapeutic bandaging of the distal limb of a horse has traditionally been used to prevent "filling of the leg" in stabled or convalescing horses. This is typically done to assist in the prevention of fluid build-up in their lower legs, which is a common problem in older or injured horses when they are confined to a small area such as a stable for a period of time. It is recognised that freedom of movement is essential for the correct function of the equine lymphatic system.
  • Competition horses frequently travel for long durations to participate in competition. Whilst travelling they are confined for their own safety to standing in a small partition within a horsebox or air freight stall which prevents or limits movement. Therefore long periods of immobility can be experienced, whilst bracing themselves to travel motion patterns. This can affect the soft tissue integrity of the distal limb. Thus, travel has the inherent risk of impairing a horse from being able to perform at their best in the ensuing competition, or hindering their post-performance recovery rate.
  • Travel can also result in an increase in dehydration and there is a possible reduction in oxygen levels in air travel, which can also affect the biochemistry of soft tissue function.
  • Travel induced oedema in humans may cause blood pooling or a build-up of excess fluid in soft tissue. These fluids are gravity dependent and pool as a result of enforced immobility.
  • a horse can be similarly affected, which can reduce the effectiveness of the horse's natural biological systems that counteract gravity. Horses can experience similar swelling of the interstitial spaces, particularly as a result of enforced immobility, either during
  • fluid When not in transit, fluid may build up in the insterstitium of the distal limb for a variety of veterinary or management reasons. This may result in general swelling, frequently referred to as “filled legs” or “stocked legs”, or localised soft swellings such as wind galls. Also, pooling of lymphatic fluid in the lower legs is believed to occur within the numerous lymph vessels and nodes, which have also recently been found by German researchers within the tendons of the distal limb.
  • Horses that perform at high levels of competition such as all forms of racing, eventing, show jumping, dressage, endurance and polo can experience performance related injuries such as micro-traumas, micro-tears, oscillation and concussion to the soft tissue and joints from ground reaction force pressures. These can occur from a combination of accelerating, decelerating, sprinting or endurance at high speed; impact from take-off and landing from all disciplines of jumping fences; and rotation and torque of twisting in non-linear movement patterns. These performance pressures need to be negated as quickly as possible post-performance so that a high level of re-performance can occur.
  • intervals of cold therapy and correctly applied compression assists repair of connective tissue by supporting the skin to help prevent the build up of oedema, which facilitates and accelerates the recovery and healing process.
  • This pro -active intervention helps offset the performance incurred pressure from ground force reactions and helps to protect the longevity of the competition horse's career.
  • the present invention may be beneficial to post-operative or trauma wound care or post-trauma oedema, so that a Veterinary Surgeon can pre-determine the most beneficial level of compression that would enhance the rehabilitation rate; and provide continuity of care when the horse moves from professional nursing to being cared for in a non-clinical environment.

These elastic yarns provide the Circumferential elasticity along their length, and provide the longitudinal elasticity perpendicular to their length by means of their separation from one another upon the application of a longitudinal force. The extension along the length of the sock is therefore constrained by the tightness of the weave of the non-elastic yarn and accordingly a lower tension in the looser weave in the second area gives a greater longitudinal elasticity in that area.

The effect of wicking is twofold, firstly it helps keep the horse's skin dry under the sock, and secondly as energy is required to evaporate the water, and as the source of that energy is heat from the horse's legs, the socks can assist in cooling the horse's legs.

Abstract

La présente invention concerne une chaussette de compression pour cheval (2) pouvant être utilisée pour la récupération post-performance ou pour un usage thérapeutique. La chaussette (2) comprend un premier tube de matériau (4) qui entoure la partie inférieure de la jambe d'un cheval et qui comprend une ouverture pouvant être fermée s'étendant le long d'au moins une partie de sa longueur. Le tube (4) est composé de panneaux de matériau présentant deux propriétés différentes. La partie principale de la chaussette (24) présente une certaine élasticité dans le sens de sa longueur et autour de sa circonférence. La seconde partie (26) forme un panneau situé à l'intérieur du premier panneau (24) et en direction de son extrémité inférieure de sorte que la seconde zone (26) recouvre l'arrière de l'articulation du boulet lors de l'utilisation. La seconde partie (26) présente également une certaine élasticité dans le sens de sa longueur et autour de sa circonférence. L'élasticité dans le sens de la longueur de la seconde section (26) est supérieure à l'élasticité dans le sens de la longueur de la première section (24) afin de correspondre à la cinématique de l'articulation.
