The Biomechanics of Walking: Brain Coordination, Peripheral Pulley Systems, and Rapid Reorganization

Human walking is a complex movement coordinated by both nerve impulses from the brain and peripheral collagenic pulleys. These pulleys act like puppet strings, synchronizing the movements of the lower limbs with the contralateral upper limbs.

Despite various instruments used for gait analysis, they fail to explain how the brain manages both walking kinematics and dynamic modifications. The body requires rapid motor reorganisation to prevent falls during unforeseen events like stumbling.

Peripheral motor coordination, driven by the stretch of fascia acting on muscle spindles and Golgi tendon organs, allows for rapid activation of motor schemes. This anticipatory mechanism supports immediate adaptation to new events during walking. This stretch is organised in myofascial sequences, diagonals, and spirals.
