This book provides an explanation of how to treat soft tissue dysfunction and prevent the development of chronic injuries in sports training and exercise. The author uses a modality he terms integrative systemic dry needling (ISDN) that is different from both conventional dry needling and from classic acupuncture, although it shares the same physiological mechanisms as both these methods. The basic techniques of ISDN draw from the acupuncture concepts put forward in Chinese medicine. Conventional dry needling acupuncture is based on the definition put forward by Travell and Simons, e.g., "needling of the soft tissue without injection of any liquid substance to treat human pathology." ISDN incorporates both dry needling and intramuscular stimulation, synthesizing them into a unified pathophysiological system. Chapters include overtraining syndrome, acu-reflex physiology, neuroanatomy, and homeostasis, trigger points and ISDN, visceral pain, pathomechanics of the acu-reflex points, general principles of treatment, preventive and therapeutic treatment of injuries in selected sports, and safety issues in practice.
