15 Jan Exercise and Pain
Strength coach Michael Boyle and Physical Therapist Gray Cook have written about the Joint by Joint Approach.
There are principles of human movement dictated by biomechanics of the joints. All joints need full range of motion, and at the same time they require stability from surrounding muscles to maintain their proper axis of rotation (the centerline through a joint about which proper motion occurs). Here is a review from the ground up.
Joints that need mobility are the foot and ankle, hip, thoracic spine, upper cervical spine. Joints that need stability include the knee, lumbar spine, shoulder girdle, and lower neck. Participating in strength training, other exercise or sport when the body has poor movement of joints lacking proper mobility or stability is inviting injury. Poor applications of exercise can lead to injury. Addressing and correcting movement dysfunction is essential to optimizing performance, ensuring proper movement, and preventing injury.
