Human gait is a remarkably intricate process that integrates neural control, musculoskeletal dynamics, and biomechanical coordination. Historically, gait analysis has focused predominantly on lower limb mechanics, with much of the emphasis placed on stride length, cadence, joint kinetics, and energy expenditure in the legs. However, this lower limb-centric perspective overlooks the critical role of upper limb movement—specifically, arm swing—in the regulation of dynamic stability and locomotor efficiency.
