Effect of Auditory Stimuli on the Human Body Biomechanical Stability during Gait Cycle

Abstract

Biomechanical stability of the human body during a gait cycle is an important parameter of biomedical assessments in the rehabilitation / recovery of people who have suffered an injury or to improve athletic performance. During the recovery actions or increasing in performance activities, can result a number of audio-visual stimuli, which may change accordingly, positively or negatively, specific actions on dedicated procedures. The research presented in this paper aims at assessing the impact of a set of auditory stimuli with negative emotional components and positive respectively, the behavior of a sample of subjects during a gait cycle. The recordings are made with afoot scansystem type "RSScan" which allows measurements of contact forces between the leg and the ground, on the entire plantar surface, measurements of the parameters during gait cycle and not least, comparative evaluation of forces, trajectories and speed changes of plantar surfaces between the left/right foot. During a gait cycle, the human subject is audio "stimulated", to track the effect of these stimulation on the biomechanical stability, on behavioral reaction of the entire human body, especially on the plantar surface which provide bipodal support. Results of this research are a starting point for specific analyzes in various biomedical or human performance situations.
