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: …

Emg Analysis Of Latissimus Dorsi, Erector Spinae And Middle Trapezius Muscle Activity During Spinal Rotation: A Pilot Study, Jamie Flint, Toni Linneman, Rachel Pederson, Megan Storstad

Physical Therapy Scholarly Projects

Purpose/Hypothesis: Rotation of the spine, a complex movement that has yet to be fully understood, occurs regularly in activities of daily living (ADLs) and sport performance. Rotation (twisting) of the spine is a contributing factor in low back pain pathology and, by reports, has been associated with up to 60% of all back injuries. One of the largest muscles of the back, the latissimus dorsi (LD), is the only muscle to attach to the spine, pelvis, ribs, scapula, and humerus, and has the potential to impact the spine during many different activities. To date, there is limited research on …

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 …
