    Abstract

    Chaos is the deterministic yet non-periodic behaviour of a system [1]: every chaotic cycle is physically determined by an unbroken chain of observations, but which gives results that appear unpredictable [2]. Chaos theory has been applied to gait variability previously (e.g. [3], [4]) and may be useful in providing an insight into the biomechanical effect of musculoskeletal pathology [3]. Current technology facilitates extensive data collection, ideal for gait variability studies, and we wished to utilise this capability to simultaneously investigate variability in ankle, knee and hip flexion over a 20 minute period.
