Performance Impact Of Different Lower-Limb Setup Positions In The Backstroke Swimming Start, Gordon E. Barkwell 2018 The University of Western Ontario

Performance Impact Of Different Lower-Limb Setup Positions In The Backstroke Swimming Start, Gordon E. Barkwell

Electronic Thesis and Dissertation Repository

The performance impact of different knee extension angles in the setup position for a backstroke start was evaluated using an instrumented starting surface. Ten backstroke swimmers completed maximum-effort starts in each of two setup positions: one with the knees flexed, and one with the knees extended. The start handles and touchpad were instrumented with tri-axial force plates. Activity of major hip and knee extensors was measured using surface electromyography. Body position was recorded throughout the start using two high-speed cameras. There was no difference in time to 10 m between the two conditions, indicating there is likely no advantage in ...


Motor Variability In Rowing, Maude Potvin-Gilbert 2018 The University of Western Ontario

Motor Variability In Rowing, Maude Potvin-Gilbert

Electronic Thesis and Dissertation Repository

The aim of the study was to analyze the impact of environment, intensity and distance rowed on temporal variability of strokes and on knee angle variability. 11 participants rowed 2,000 m at high and low intensities on an ergometer and at high intensity in a single on-water. Data were collected at the beginning and at the end of each exercise. All the factors influenced significantly the temporal variability (respectively beta=-0.013 and p .007=; beta= 0.007 and p=.021; beta=0.06 and p=.028). The difference of visual information and the need of the rower to ...


Exoskeleton Assistance Symmetry Matters: Unilateral Assistance Reduces Metabolic Cost, But Relatively Less Than Bilateral Assistance, Philippe Malcolm, Samuel Galle, Pieter Van den Berghe, Dirk De Clercq 2018 Ghent University

Exoskeleton Assistance Symmetry Matters: Unilateral Assistance Reduces Metabolic Cost, But Relatively Less Than Bilateral Assistance, Philippe Malcolm, Samuel Galle, Pieter Van Den Berghe, Dirk De Clercq

Journal Articles

Background: Many gait impairments are characterized by asymmetry and result in reduced mobility. Exoskeletons could be useful for restoring gait symmetry by assisting only one leg. However, we still have limited understanding of the effects of unilateral exoskeleton assistance. Our aim was to compare the effects of unilateral and bilateral assistance using a within-subject study design.

Methods: Eleven participants walked in different exoskeleton conditions. In the Unilateral conditions, only one leg was assisted. In Bilateral Matched Total Work, half of the assistance from the Unilateral conditions was applied to both legs such that the bilateral sum was equal to that ...

Control Of Redundant Pointing Movements Involving The Wrist And Forearm, Garrett R. Dorman, Kevin C. Davis, Allan W. Peaden, Steven K. Charles

All Faculty Publications

The musculoskeletal system can move in more ways than are strictly necessary, allowing many tasks to be accomplished with a variety of limb configurations. Why some configurations are preferred has been a focus of motor control research, but most studies have focused on shoulder-elbow or whole-arm movements. This study focuses on movements involving forearm pronation-supination (PS), wrist flexion-extension (FE), and wrist radial-ulnar deviation (RUD), and elucidates how these three degrees of freedom (DOF) combine to perform the common task of pointing, which only requires two DOF. Although pointing is more sensitive to FE and RUD than to PS and could ...

Experimental Measurement Of Dolphin Thrust Generated During A Tail Stand Using Dpiv, Frank E. Fish, Terrie M. Williams, Erica Sherman, Yae Eun Moon, Vicki Wu, Timothy Wei 2018 West Chester University of Pennsylvania

Experimental Measurement Of Dolphin Thrust Generated During A Tail Stand Using Dpiv, Frank E. Fish, Terrie M. Williams, Erica Sherman, Yae Eun Moon, Vicki Wu, Timothy Wei

Biology Faculty Publications

: Estimation of force generated by dolphins has long been debated. The problem was that indirect estimates of force production for dolphins resulted in low values that could not be validated. Bubble digital particle image velocimetry (DPIV) measured hydrodynamic force production for swimming dolphins and demonstrated high force production. To validate the bubble DPIV and reconcile force production measurements, two bottlenose dolphins (Tursiops truncatus) performing tail stands were measured with bubble DPIV. Microbubbles were generated from a finely porous hose and compressed air source. Displacement of the bubbles by the propulsive motions of the dolphin was tracked with a high-speed video ...


Gait Stability Has Phase-Dependent Dual-Task Costs In Parkinson’S Disease, Peter C. Fino, Martina Mancini, Carolin Curtze, John G. Nutt, Fay B. Horak 2018 Oregon Health and Science University

Gait Stability Has Phase-Dependent Dual-Task Costs In Parkinson’S Disease, Peter C. Fino, Martina Mancini, Carolin Curtze, John G. Nutt, Fay B. Horak

Journal Articles

Dual-task (DT) paradigms have been used in gait research to assess the automaticity of locomotion, particularly in people with Parkinson’s disease (PD). In people with PD, reliance on cortical control during walking leads to greater interference between cognitive and locomotor tasks. Yet, recent studies have suggested that even healthy gait requires cognitive control, and that these cognitive contributions occur at specific phases of the gait cycle. Here, we examined whether changes in gait stability, elicited by simultaneous cognitive DTs, were specific to certain phases of the gait cycle in people with PD. Phase-dependent local dynamic stability (LDS) was calculated ...


Biomechanical Gait Variable Estimation Using Wearable Sensors After Unilateral Total Knee Arthroplasty, Ik-Hyun Youn, Jong-Hoon Youn, Joseph A. Zeni, Brian A. Knarr 2018 Mokpo National Maritime University

Biomechanical Gait Variable Estimation Using Wearable Sensors After Unilateral Total Knee Arthroplasty, Ik-Hyun Youn, Jong-Hoon Youn, Joseph A. Zeni, Brian A. Knarr

Journal Articles

Total knee arthroplasty is a common surgical treatment for end-stage osteoarthritis of the knee. The majority of existing studies that have explored the relationship between recovery and gait biomechanics have been conducted in laboratory settings. However, seamless gait parameter monitoring in real-world conditions may provide a better understanding of recovery post-surgery. The purpose of this study was to estimate kinematic and kinetic gait variables using two ankle-worn wearable sensors in individuals after unilateral total knee arthroplasty. Eighteen subjects at least six months post-unilateral total knee arthroplasty participated in this study. Four biomechanical gait variables were measured using an instrumented split-belt ...
