Bio class

 Introduction       Biomechanics  is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole  organisms  to  organs to   cells ,  using the methods of  mechanics .  Biomechanics is a branch of  biophysics .            Arthritis is an inflammation of the joints. It can affect one joint or multiple joints. There are more than 100 different types of arthritis, with different causes and treatment methods. Role of biomechanics Biomechanic s play an important role in the health of diarthrodial joints. Altered joint loading is associated to obesity, malalignment, trauma, or joint instability is a critical risk factor for joint degeneration, whereas exercise and weight loss have generally been shown to promote beneficial effects for osteoarthritic joints. Under physiologic conditions, joints of the body are subjected to millions of cycles of loading resulting in forces of up to ten times body weight passing through the joint
