Actually, the initials are PST which stands for Pulsed Signal Therapy. This technology has been used extensively on humans and is now available for dogs, cats, and other small animals. It is a therapy that significantly helps joint pain, joint and muscle tenderness, painful motion, joint inflammation and helps improve mobility, sleep and general activities of daily living (paraphrased from pstvet brochure).
All I can say is the dogs that Dr. Tami Shearer sees, love this treatment and benefit from it greatly. Dr. Shearer specializes in treating and caring for animals in chronic pain. Shearer Pet Health Hospital in Sylva, NC gets referrals from around the area for her special treatment of these pets. PST is a non-invasive therapy that assists new bone and cartilage growth as well as the benefits listed above. It is an honor for me to work with Dr. Tami monthly at her clinic providing chiropractic care for the same population of animals.
So what is PST? The device emits pulsed signals (very comfortable to your pet) while the animal lies and rests. It is non-surgical and painless therapy that has no documented side effects. We use this treatment as an effective alternative to NSAIDs (anti-inflammatory drugs) and analgesics (pain relievers) and it bypasses possible side effects of these drugs.
I use a form of PST called PEMF (pulsed electromagnetic force) with patients at my human office and with horses and dogs as well. It is a slightly different device with the same benefits as PST. A bit easier to use with humans. My personal experience is amazing improvement with pain level and function of my knee in which I tore the ACL completely (chronic) and injured the medial meniscus (acute). [I then was able to exercise and strengthen the surrounding muscles because of reduction in pain level]. When used with horses the changes in range of motion and decreased pain in an area is dramatic.
