Hock/Tarsal Pain or Injury – Chronic

Hyperextension with secondary pain, osteoarthritis, osteochondrosis (OC), osteochondrosis dissecans (OCD), Achilles/calcaneal tendon strain/rupture/tendinopathy.
  1. A small Assisi Loop can be used to treat the hock joint in small to medium dogs.  A large- or giant-breed dog should use a large Loop.  If both hocks are to be treated simultaneously, a large Loop should be utilized.  Positioning is extremely important for optimal effect.
  2. Position the pet lying down either flat on the ground or up on their elbows with their rear limbs out to one side.
  3. Identify the hock/tarsal joint(s) and place one or both joints in the treatment area.  Lay the Assisi Loop over the area or if both hocks are to be treated then place the Loop between the hocks so as to treat them simultaneously.  See Pictures
  4. The signal generator can be positioned to help balance and stabilize the unit during treatment.
  5. The signal generator should be located in view of the person treating the pet.
  6. Do not leave the pet unattended when using this placement as small movements can change the positioning of the Loop and the area being treated.
  7. Turn the unit on by pressing the button on the front of the white rubberized signal generator; green lights will illuminate about once per second.
  8. Keep the unit in place for the full 15 minutes until the unit shuts off.
  9. Use the Assisi Loop 4 times daily, if possible, for 10 days or until there is improved mobility and pain is greatly decreased or eliminated.  Use of the Loop can be tapered down to 1-2 times daily as the condition improves. Long-term chronic conditions may require as much as 3-6 weeks before tapering would be appropriate.  If symptoms resolve and regular use of the Assisi Loop ceases, use the Assisi Loop as needed if pain starts to recur.  If there is an acute injury at a hock/tarsal joint that has chronic disease, follow the steps in “Hock/Tarsal Pain or Injury – Acute” until all pain is resolved.
  10. There should be a minimum of 2 hours between treatments for optimal nitric oxide enhancement.
  11. It is common to utilize the Assisi Loop after long walks or unusual activity when chronic hock issues exist.
  12. For those treating osteoarthritis in multiple parts of the body: The Loop is only guaranteed to last the minimum 150 treatments if it is not used more frequently than once every 2 hours: If you are treating OA in multiple parts of the body, you will need to treat EACH AREA at least twice per day. We recommend:
    • Using more than one Loop so you can treat multiple areas during the same 15 minute period
    • Use the same Loop for multiple areas, waiting 2 hours between treatments
    • Use the Loop more frequently than every 2 hours, knowing that the battery may last for significantly fewer treatments and negate the warranty

Battery Life: When the lights are blinking 2-3 times per second, the battery is running low and a new Assisi Loop should be purchased. There should be a minimum of 2 hours between treatments for optimal battery efficiency.
