Assisi Animal Health is pleased to share with the veterinary community, the publication of results by the Journal of the American Animal Hospital Association (JAAHA) from an independently conducted study.  The trial was completed at The Animal Medical Center, New York, under the direction of Leilani Alvarez, DVM, DACVSMR. The trial, which evaluated the Assisi Loop® as the therapeutic agent, demonstrated statistically significant improved wound healing scores 6 weeks post-operatively.  Of particular note is the nearly 50% reduced opioid use in the actively treated subjects. 

The abstract of the study was awarded 1st place by the American College of Veterinary Sports Medicine and Rehabilitation (ACVSMR) in the category of canine research, and was presented at ACVS on October 26th 2018.  Abstract details are now available on the Assisi Animal Health website ( on the research page.  Publication of the study is in the March-April issue of JAAHA:

Study Specifics:

  • PEMF therapy using the Assisi Loop was administered to 53 client owned dogs that underwent hemilaminectomies for naturally occurring disk extrusion IVDD
  • Dogs were randomized to receive either targeted PEMF (N=27) or sham treatment (N=28).
  • Study was conducted at the Animal Medical Center (NY)

Key Benefits of Loop Therapy Identified Include:

  • Statistically significant improvement in wound healing scores 6 weeks post-operatively for Loop treated group compared with placebo
  • Statistically significant reduction in use of pain medication in Loop treated group compared with placebo.  Opioids were administered almost 50% less frequently by owners in Loop treated group in the initial 7 day post-operative period.
  • No side effects were seen with Loop treatment
