What causes muscle and/or fascial restriction?

Muscle and fascial restrictions are often caused by decreased elasticity of myofascial and ligamentous tissues. This decreased elasticity can result from various factors, including sustained postures, repetitive motions, trauma, or lack of movement, leading to tightness and reduced flexibility in those tissues. When fascia and ligaments lose their elasticity, they can become more rigid and less able to accommodate movement, which can contribute to restrictions in muscle function and mobility.

Additionally, myofascial tissues play a critical role in the overall movement patterns of the body. If these tissues are not pliable, it can lead to dysfunctional biomechanics, inducing further restrictions. This condition can also manifest as pain, stiffness, and limited range of motion, impacting overall physical performance.

While decreased elasticity of skeletal muscles, overuse of muscles, and injuries to tendons can contribute to discomfort and limitations, the core issue of fascial and ligamentous restriction is fundamentally tied to their decreased elasticity, often leading to the various compensatory patterns and restrictions observed in clinical practice.
