This study aimed to investigate how external perturbations caused by the treadmill belt’s deceleration during pre-swing phase affect gait kinematics and kinetics in young adults. Twenty-one healthy females walked on a virtual environment (GRAIL, Motek), where unexpected were applied left belt, mimicking ‘trip-like’ effect at toe-off. The spatiotemporal, kinematic, kinetic parameters analyzed two cycles. first cycle involved perturbation response it. second included without (treadmill gait). resulted an increased stride duration for both limbs when compared gait. perturbed limb had longer support phase, while reactive longest double stance phase. responding exhibited more than ankle plantarflexion normal limb. At hip joint, showed significantly higher values, with 40.8% increase flexion 227% extension limb, 24.5% 212% Muscle torque was generally lower most joints limbs, except notably knee extensor values ankle, knee, joints, indicating muscle activity patterns. Studying belt can provide valuable insights into biomechanical adaptations motor control strategies.

Background: Humans encounter disturbances like slips, pushes, and trips while walking, mainly from external forces. Technological advances have improved methods to study these impacts on gait, with split-belt treadmills being particularly effective. This scoping review aims examine the types of perturbations used during treadmill explore induce them, consolidate current knowledge effects treadmill-induced gait perturbations. Methods: The included publications January 2015 May 2024, as searched via PubMed, EBSCO, ScienceDirect. Results: examined 33 studies treadmills, focusing slip-like, trip-like, lateral displacements, tilts, speed changes most common. Perturbations were applied initial contact. results show that young, healthy adults adapt quickly anticipatory reactive adjustments, older those neurological impairments use less efficient strategies increased muscular co-contraction. Asymmetrical adaptations persist after perturbations, highlighting motor learning role central nervous system sensory feedback. Conclusions: Despite their precision, tilting may not fully replicate real-world walking complexities. highlights strengths limitations emphasizing need integrate diverse enhance rehabilitation improve stability.
