Normal movement is achieved through the integration of fundamental movement patterns with an adequate balance of mobility and stability to meet the demands of the task at hand.

The human system will migrate toward predictable patterns of movement in response to pain or in the presence of weakness, tightness, or structural abnormality. Over time, these pain-attenuated movement patterns lead to protective movement and fear of movement, resulting in clinically observed impairments such as decreased ROM, muscle length changes, and declines in strength. An isolated or regional approach to either evaluation or treatment will not restore whole function. Functional restoration requires a working knowledge of functional patterns and a map of dysfunctional patterns to gain clinical perspective and design an effective treatment strategy.

K-Star put out some good videos on achieving some better ROM, http://journal.crossfit.com/2010/06/kstarr-2min-1.tpl
