Electromyographic Analysis Of Hip Muscle Activity During Stair Climbing: A Pilot Study, Alexander Barney, Mary Loken, Paige Torgerson, Lyndsey Wunderlich

Physical Therapy Scholarly Projects

Introduction: Prior to this study, little evidence exists for a quality predictive tool correlating maximum velocity contraction (MVC) strength of the hip abductor muscles to walking and stair climbing (ascending/descending, side-stepping) ability. Stair climbing is an important functional activity of daily living and as physical therapists we are involved in training clients to ascend/descend stairs safely, which can be difficult for clients with hip abductor muscle weakness. Subjects: Eleven females voluntarily agreed to participate in this study. All participants were under the age of 30 years old, nonpregnant, physical therapy students without a current musculoskeletal injury. Methods: …

Electromyographic Analysis Of Sit To Stand Dependent Transfers With And Without Education On Lifting Technique, Jordan Braun, Samantha Stegman, Alex Wohl

Physical Therapy Scholarly Projects

PURPOSE: The purpose of this study was to assess if there was a change in electromyography (EMG) activity in the back or leg muscles when performing a dependent sit-to-stand lift before and after a brief proper lifting intervention.

SUBJECT: The subjects in this study included 10 female third-year doctoral physical therapy students from the University of North Dakota that were all in good health with no significant pathology of either their backs or lower extremities.

INSTRUMENTATION: The EMG activity was recorded by the Noraxon ™ TeleMyo 2400R G2 transmitter and a TeleMyo 2400 SG150 unit. Knee flexion …
