Characterizing Locomotor Disturbance Perception In Young Adults, Daniel James Liss
Characterizing Locomotor Disturbance Perception In Young Adults, Daniel James Liss
Graduate Theses, Dissertations, and Problem Reports
Falls during walking are a leading cause of injuries across aging. Many of these falls are due to slips and trips. The ability to perceive disturbances to ongoing motion may play an important role in the control of walking balance. However, disturbance perception has been investigated in standing balance, but its role in walking balance due to slip- and trip-like disturbances remains largely unknown. Characterizing locomotor disturbance perception in young adults may lead to a more comprehensive understanding of sensorimotor walking balance control.
This work defined locomotor disturbance perception in response to slip and trip-like disturbances in young adults. We …
Reliability Of Gastrocnemius Pennation Angle Using Ultrasound With 15 Degree Adduction And Abduction In Standing Position, Diana J. Tyler
Reliability Of Gastrocnemius Pennation Angle Using Ultrasound With 15 Degree Adduction And Abduction In Standing Position, Diana J. Tyler
Honors College Theses
A pennate muscle has fascicles that attach obliquely to its tendon. In parallel, more fascicles can be aligned allowing for greater production of force. In previous research, pennation angle has been measured using ultrasound while in a laying supine position. The purpose of this study was to measure pennation angle of the gastrocnemius muscle with ultrasound while standing neutral, in a mechanically loaded position. 16 participants, one two separate days, had their ultrasound imaging taken in three different foot orientations: neutral, fifteen degree adduction / abduction positions. This information was then be analyzed using ImageJ software. This research shows the …
