Efficacy Of Electromyography And The Dead Bug Exercise, Taylor M. Scavo, Rachel C. Cooklin, Erika N. Faria, Madeline L. Johnson, Eric Sternlicht

Student Scholar Symposium Abstracts and Posters

The Dead Bug exercise is performed in physical therapy clinics to restore lumbar spine stability and core strength in patients with lower back pain (LBP). The aim of this study was to evaluate the efficacy of using electromyography (EMG) feedback to enhance proper mechanics during the Dead Bug exercise. Sixteen healthy, college age students volunteered as subjects for the study. Subjects performed the Dead Bug (Fig. 1a.) with and without visual EMG cues and were given instructions on how to execute the exercise. Data was recorded using a BTS FREEEMG Analyzer and signal processed and data analyzed using the BTS …

The Use Of Emg As A Physical Therapy Learning Aid, Madeline L. Johnson, Rachel C. Cooklin, Erika N. Faria, Taylor M. Schavo, Eric Sternlicht

Student Scholar Symposium Abstracts and Posters

The purpose of this study was to compare the muscle recruitment of an agonist and antagonist muscle during the step up physical therapy exercise with and without visual electromyographic (EMG) biofeedback. 15 healthy, college-aged subjects were recruited to participate in the study. Subjects performed the step up with and without visual feedback in two separate sessions over a four week period. Muscle activity was recorded from the Vastus Medialis (VMO) of the target leg and Medial Gastrocnemius on the contralateral leg. EMG recordings were collected using a BTS FREEEMG system and data was processed using BTS SEMGanalyzer software (BTS Bioengineering, …

Electromyographic Activity Of Hamstrings And Quadriceps Muscles During Jumping And Landing: Pilot Study, Joseph Burckhard, Tyler Kemnitz, Mikaela Dick, Alexandria Sweeney

Physical Therapy Scholarly Projects

Background and Purpose. The purpose of this pilot study was to find if there was a difference in the activation and firing time of the quadriceps (vastus medialis and vastus lateralis) compared to activation times of the hamstrings (biceps femoris and semitendinosus) in active males and females.

Methods. Subjects consisted of two male and two female athletes in good physical condition with no previous knee pathologies. During each of the trials, the muscle activity of each muscle was recorded. The EMG activity recorded using a Noraxon TeleMy02400 G2 telemetry unit with a sampling rate of 1 kHz which …
