Here is a Series of Articles by David Scott Lynn (DSL) discussing the Nature and Causes of Yoga Injuries and How to Prevent them:
Many years ago, DSL used yoga successfully to get himself out of MUCH pain and various dysfunctions. He still uses it today to manage old injuries that damaged his structure considerably and maintain the positive results he achieved. Yet other people, even World Class, highly trained teachers, have suffered yoga injuries.
He also uses Yoga Therapy with Clients, and originally based his system of yoga-based, hands-on bodywork therapy (known as Psycho-Muscular Release in his earlier days of teaching) on the principles of physical / mental and relational yoga, as he learned, primarily, from Joel Kramer. Joel was a foundational thinker and teacher in authentic American Yoga, a highly conscious yet non-mystical approach to integrating meditative mind with physical postures.
Conscious Stretching Errors & Yoga Injuries
Upon learning how many people had suffered yoga injuries of various degrees from over-stretching, even “conscious stretching,” DSL set out to provide insights, information and techniques on how to use it most effectively and simultaneously prevent related injuries.
