Temperature Changes Seen In Lower Extremities After Cpn Local Anesthetic Block, Lora Asberry Aug 2021

Temperature Changes Seen In Lower Extremities After Cpn Local Anesthetic Block, Lora Asberry

Symposium of Student Scholars

Many older patients often suffer from walking issues such as Drop Foot. Drop Foot is caused by the malfunction of nerves in the foot, resulting in the loss of control of the front foot muscle. Within all of our patients, there has been a common fibular palsy, caused by the entrapment of the peroneal nerve. Due to this, they cannot lift up their foot. Some cases are permanent, while others are temporary. In the temporary cases, we have indicated a Phoenix Sign. The Phoenix Sign indicates that a nerve, presumed to be dead, has the capability to be recessed back …


Age-Related Reduction In High-Velocity Power And Myofiber Morphology And Composition, Ben Dalton Aug 2021

Age-Related Reduction In High-Velocity Power And Myofiber Morphology And Composition, Ben Dalton

Symposium of Student Scholars

Power is diminished more dramatically at higher contraction velocities in older adults. It has been suggested that this may reflect age-related changes in single myofiber morphology or composition. PURPOSE: To examine power, muscle activation, and single myofiber morphology and composition between young (YM) and older (OM) males. METHODS: Power, or torque × velocity, was recorded during isokinetic knee extensions at 60°·s-1 and 180°·s-1 in healthy, untrained YM (n=15; 20.7±2.2 yrs) and OM (n=15; 71.6±3.9 yrs). The relative increase in power from 60°·s-1 to 180°·s-1 was recorded for each participant. Electromyography amplitude of the vastus lateralis (VL) …
