Please note: This is a companion version & not the original book. Sample Book Insights:#1 The challenge is figuring out what to assess. Some experts believe that more emphasis should be put on a patient’s history, while others believe that the psychological state should be assessed first.#2 The nervous system will often create stiffness in a muscle as a protective mechanism. This protective tension is a common problem in healthy clients who don’t have a recent injury. To better understand why this happens, and what you can do to correct it, we’ll start by discussing the relationship between mobility and stability.#3 Optimal movement requires a hand-in-hand balance of mobility and stability. Mobility is achieved when the soft tissues, muscles, fascia, and joint capsules, have the extensibility to allow the joints to move through a full range of motion without restriction imposed by the nervous system. Stability is achieved when key muscles can contract at the precise time and with enough force to provide stiffness where it is needed.#4 The iliotibial band syndrome, an overuse injury of the IT band, is one of the most common injuries in runners. Some research suggests that weakness of the glutes, particularly the gluteus medius, could be a contributing factor.
