Joint stability is often defined as the state of a joint remaining or promptly returning to proper alignment through an equalization of forces. KI expands on this definition by including the following: the level of stability of a joint is defined by how it responds to perturbations. Thereby, a stable joint possesses the ability to manage
perturbations while performing a dynamic task, while an unstable joint cannot. In fact the unstable joint cannot manage perturbations effectively, resulting in movement dysfunctions and the need of external support. Sum of Sums, add perturbation training to your workout, training or rehabilitation programs!! http://www.ncbi.nlm.nih.gov/pmc/articles/PMC164311The Sensorimotor System, Part I: The Physiologic Basis of Functional Joint Stability
Data Sources: Information was drawn from an extensive MEDLINE search of the scientific literature conducted in the areas of proprioception, neuromuscular control, and mechanisms of functional joint stability for the years 1970 through 1999. An emphasis was placed on defining pertinent nomenclature b...
