Fields studying movement generation, including robotics, psychology, cognitive science,
and neuroscience utilize concepts and tools related to the pervasiveness of variability in …

Several recent reviews have reported that 'repetitive movements' constitute a risk factor for
occupational musculoskeletal disorders in the neck, shoulder and arm regions. More …

It is widely accepted that humans and animals minimize energetic cost while walking. While
such principles predict average behavior, they do not explain the variability observed in …

Although anecdotal reports suggest that information processing and decision making is
impaired immediately following prolonged periods of physical activity, results obtained from …

Locomotor variability is inherent to movement and, in healthy systems, contains a
predictable structure. In this study, detrended fluctuation analysis (DFA) was used to quantify …

Fatigue is the subjective sensation of weariness, increased sense of effort, or exhaustion
and is pervasive in neurologic illnesses. Despite its prevalence, we have a limited …

Muscle fatigue may alter kinematics and contribute to repetitive strain injuries. This study
quantified how both localized muscle fatigue and movement kinematics change over time …

A recent systematic review identified 73 empirical studies that linked human factors (HF) with
manufacturing quality. Human fatigue was noted as a frequent (n= 26) issue in the HF …

People produce multi-joint movements by organizing many degrees of freedom into a few
major covarying relationships, indicating a high level of inter-joint coordination. These …

Repetitive movements are common to many daily activities but often lead to the
development of fatigue. We have previously shown that fatigue leads to changes in …
