Hilton’s Law[1] forms the basis of the relationship between the structural elements of our musculoskeletal system; it states that the nerve supplying a joint also supplies both the muscles that move the joint and the skin covering the articular insertion of those muscles. The innervated parts of joints consist mainly of three ligamentous structures; the ligaments that hold the joints together, the capsule that encases the joint, and the synovium …
What is Posture? Do you ever notice when you see people with good posture? They walk erect, their heads lifted, shoulders back, their arms swing evenly, and they move with a simple, efficient gait. Unfortunately, most of us have some structural imbalance that causes us to alter our posture. Many people think that by stiffening their back to stand up straight, they are correcting their posture but the tension in …
During normal anatomical standing, with balanced weight bearing, the spine should not be laterally flexed or rotated. The sacral apex should be neutral, evenly spaced between the right and left ischia. The height of the ilia should be even, with no rotation. If I am correct, this pattern may not exist on any back-pain patients. CLARIFYING SIJ MOVEMENT Balanced Movement In normal movement of the spine, most vertebrae move in …
With joint injury, sprained ligaments initiate a complex chain reaction as the body compensates for the resulting hypermobility. To explain this better, we should consider that ligaments serve two main functions, proprioception and joint stability. Proprioception is a means of sensing the movement pattern of the joint, including direction, speed, and acceleration, and then balance the tension of the muscles to maintain even, smooth movement; this is an essential component …
