Cannon's Law


Normal nerve and muscle depend upon intact innervation to provide regulatory or "trophic" effect. It has been shown that any measure which blocks the flow of motor impulses and deprives the effector organ of excitatory input for a period of time can cause "disuse supersensitivity" in that organ, as well as in associated spinal reflexes. Supersensitive nerves and innervated structures react abnormally to stimuli according to Cannon and Rosenblueth’s law of denervation:


"When a unit is destroyed, in a series of efferent neurons, an increased irritability to chemical agents develops in the isolated structure of structures, the effect being maximal in the part directly denervated."


That means, when a nerve is functioning below par and is not functioning properly (neuropathy), it becomes supersensitive and behaves erratically. This principle is fundamental and universal, yet is not well-known or credited. Peripheral neuropathy parallels the aging process, most intense at the weight-bearing and mobility areas of the body.

Since the publication of the first edition in 2013, the utilization of dry needling in clinical practice has expanded dramatically throughout the world. Indeed, more and more professionals have been using dry needling to effectively reducing acute and chronic pain, as well as improving motor performance, range of motion, and strength.

Following the success of the previous edition, the updated Trigger Point Dry Needling: An Evidence and Clinical-Based Approachremains the first authoritative guide on the market.

With a completely revised text and now full colour illustrations, it provides excellent clarity within content and images for even more uniform and consistent instructions on the needling techniques.

Written and edited by a group of international experts, this is the most-up-to-date resource for physiotherapists, chiropractors, myotherapists, and other professionals as physicians, acupuncturists, osteopaths and athletic trainers.
