This document describes tendon release therapy. It explains that tendons are innervated by the autonomic nervous system and respond similarly to smooth muscles. When a tendon is hypertonic, it becomes rigid. The treatment involves applying pressure to the tendon for 1 minute to release the hypertonicity. Steps for performing tendon release on the Achilles tendon are provided as an example. Indications for tendon release therapy include tendonitis, hypertonicity, and tears/ruptures. Common tendons and disorders that respond well to the therapy are also listed.
