Ligaments and surrounding fascia of a joint provide feedback to local musculature about joint posture. Poor joint posture means the opposing surfaces of the joint do not line up or centre properly. Ligaments sense this and by neurological reflex increase muscle tone (1), reducing and stiffening joint movement (2). Poor joint posture, tight muscles and stiff joints lead to inflammation (3) and wear. Repair of this dysfunction requires optimal loading of joints, muscles, ligaments and fascia. See optimal load on the diagram below.:
From a practical stance it is ‘variety of movement’ of your body through movement, exercise, and if you are nursing an injury, rehabilitation that gives you good form and posture. Spreading a variety of loads across your muscles, joints, ligaments, and fascia as you move promotes joint proprioception, muscle strength, ligament balance and fascial bathing. Conversely, being in one posture for most of the time does not spread the load making activities such as sitting accumulatively weakening.
As fascia becomes asymmetrically loaded it is like a buckled wheel that catches on the brakes. In people this translates to reduced flexibility and a lower-than-expected straight leg raise (4). Luckily manual interventions to load fascia, that you are not using, can help to true your posture and movement. Giving you, in my opinion, the best chance of retaining your form and function, complementing your exercise efforts.
