The Biomechanics of Walking: Brain Coordination, Peripheral Pulley Systems, and Rapid Reorganization
Summary
The Biomechanics of Walking: Brain Coordination, Peripheral Pulley Systems, and Rapid Reorganization
Highlights
Complexities of Human Walking
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.
Limitations of Current Gait Analysis Instruments
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 and Adaptation
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.
