Coordination Rigidity in the Gait, Posture, and Speech of Persons with Parkinson's Disease
J Mot Behav. 2023 May 31:1-16. doi: 10.1080/00222895.2023.2217100. Online ahead of print.ABSTRACTParkinson's disease (PD) is associated with reduced coordination abilities. These can result either in random or rigid patterns of movement. The latter, described here as coordination rigidity (CR), have been studied less often. We explored whether CR was present in gait, quiet stance, and speech-tasks involving coordination among multiple joints and muscles. Kinematic and voice recordings were used to compute measures describing the dynamics of systems with multiple degrees of freedom and nonlinear interactions. After clinical...

Effect of Sway Frequency on the Joint Angle and Center of Pressure in Voluntary Sway
J Mot Behav. 2023 May 31:1-11. doi: 10.1080/00222895.2023.2211540. Online ahead of print.ABSTRACTVoluntary sway is the periodic movement of one's body back and forth. The study aimed to clarify the effects of sway frequency on center of pressure and joint angle during voluntary sway. We measured 10 unrestricted voluntary sway conditions with different frequencies and natural pace conditions. The frequencies ranged from 0.1 to 1 Hz in 0.1-Hz increments. The joint angles and centers of pressure during voluntary sway were compared between the conditions. The joint angle amplitude of the trunk and knee were greater in the slow...

Strategies Adopted by Stroke Patients to Maintain Balance in Dynamic Tasks in a Video Game
J Mot Behav. 2023 May 28:1-10. doi: 10.1080/00222895.2023.2216150. Online ahead of print.ABSTRACTPostural instability affects motor tasks after a stroke. We investigated the strategies used to maintain balance during quiet standing posture and dynamic tasks in a video game. Sixteen stroke volunteers (12 males, 56 ± 9 years, post-stroke time 35 ± 10 months) and sixteen matched healthy volunteers had their biomechanical data collected to obtain the variables: center of mass, base of support, margin of stability, and weight symmetry. Healthy individuals and stroke patients showed similar dynamic stability. However, they ado...

Somatosensory Information in Skilled Motor Performance: A Narrative Review
J Mot Behav. 2023 May 28:1-22. doi: 10.1080/00222895.2023.2213198. Online ahead of print.ABSTRACTHistorically, research aimed at improving motor performance has largely focused on the neural processes involved in motor execution due to their role in muscle activation. However, accompanying somatosensory and proprioceptive sensory information is also vitally involved in performing motor skills. Here we review research from interdisciplinary fields to provide a description for how somatosensation informs the successful performance of motor skills as well as emphasize the need for careful selection of study methods to isolate...

Imitation of Touching Dangerous Animals Triggers Motor Inhibition in a Primed Target Grasping-Categorization Task
J Mot Behav. 2023 May 24:1-13. doi: 10.1080/00222895.2023.2217109. Online ahead of print.ABSTRACTThe present study adopted a primed target grasping-categorization task and selected pictures of animals as target stimuli to investigate whether motor inhibition influences the motor interference effect of dangerous animals. The results identified more positive P2 and P3 amplitudes accompanied by larger delta event-related synchronization in the dangerous condition than in the neutral condition, suggesting that compared to neutral animal targets, dangerous animal targets attracted increased attentional resources in early proces...
