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.
