DOI: 10.1016/j.rehab.2020.05.009
Abstract: BACKGROUND Rhythmic auditory cueing has been widely studied for gait rehabilitation in Parkinson's disease (PD). Our research group previously showed that externally generated cues (i.e., music) increased gait variability measures from uncued gait, whereas self-generated… read more here.

DOI: 10.1038/s41598-020-59475-5
Abstract: Scaling sports equipment to match the physical development of children allows motor skills to be performed with greater success and with more desirable movement patterns. It is unknown, however, how scaled equipment affects movement variability… read more here.

DOI: 10.1044/2021_ajslp-20-00167
Abstract: Purpose Variability has been interpreted in differing ways according to context (e.g., development, speech impairment, and learning). A challenge arises when interpreting variability in the context of learning for children with speech impairment characterized by… read more here.

DOI: 10.1080/00222895.2017.1371109
Abstract: ABSTRACT This cross-sectional study analyzed the influence of chronic shoulder pain (CSP) on movement variability/kinematics during humeral elevation, with the trunk and elbow motions constrained to avoid compensatory strategies. For this purpose, 37 volunteers with… read more here.

DOI: 10.1080/00222895.2022.2063787
Abstract: Abstract Movement variability has been postulated to afford perception of the perceptual motor workspace and to be directly linked to improved performance. Here, we investigated how instructions mediate the search process and the relation between… read more here.

DOI: 10.1152/jn.00095.2022
Abstract: Although movement variability is often attributed to unwanted noise in the motor system, recent work has demonstrated that variability may be actively controlled. To date, research on regulation of motor variability has relied on relatively… read more here.

DOI: 10.1152/jn.00472.2022
Abstract: The naturally occurring variability in our movements often poses a significant challenge when attempting to produce precise and accurate actions, which is readily evident when playing a game of darts. Two differing, yet potentially complementary,… read more here.

DOI: 10.1152/jn.01150.2015
Abstract: Small-amplitude, higher frequency oscillations of the body or limb are typically observed when humans attempt to maintain the position of a body or limb in space. Recent investigations have suggested that these involuntary movements of… read more here.

DOI: 10.1177/1747021820940620
Abstract: When presented with two different target–penalty configurations of similar maximum expected gain (MEG), participants prefer aiming to configurations with more advantageous spatial, rather than more advantageous gain parameters—perhaps due to the motor system’s inherent prioritisation… read more here.
