Abstract
Inter-limb coordination is the relationship between limbs or body segments. In order for the body to perform effectively and efficiently on a daily basis, our limbs must be in coordination with one another. Walking is an imperative movement in any person’s daily life that requires substantial inter-limb coordination. Such knowledge is important to develop proper rehabilitation techniques because it can be applied to the rehabilitation of different pathologies. Current rehabilitation techniques generally are applied to all populations regardless of age. However, it’s been shown that aging can trigger deterioration in sensory systems like vision, proprioception, and the vestibular systems. This means people may adapt to tasks and environmental changes differently based on their age. Human movements are dynamic (i.e. evolve over time). Nonlinear analytical tools were used in this study because they captured how these movements evolve over time. All participants performed a 5-minute walk on a treadmill and their movement in anterior posterior direction was analyzed using cross recurrence quantification analysis (cRQA) as well as synchrony of coordination via cross sample entropy (cSE). The cRQA measure provides the duration of coordination between the two legs (i.e. inter-limb coordination). The cSE measure also assesses inter-limb coordination, measuring the synchrony between the two legs. By using these measures, we hope to determine how age contributes to the duration and synchrony of inter-limb coordination. We anticipate that with age, the duration of inter-limb coordination will decrease. Therefore, cRQA will be in the order: healthy young > healthy middle > healthy old.
