Variations In Emg Activity In Lower Leg Musculature With Use Of The Biomechanical Ankle Platform System (Baps), Carrie Carpenter, Andrea Lund, Jodi Sailer, Slinde Jessie

Physical Therapy Scholarly Projects

Ankle sprains account for 17% to 20% of all injuries in most sports. Other ankle conditions such as posterior tibialis tendon disorder and Achilles tendinosis are quite common in the nonathletic population and require many of the same interventions. Some of these interventions include range of motion, stretching, strengthening and proprioception. Many studies have shown that strength and proprioceptive training are the intervention of choice for those with lateral ankle instability. Many of these studies have supported the use of BAPS in improving proprioception among individuals with lateral ankle instability, however there is only one study examining the use of …

An Electromyographic Study Of Upper Trapezius, Lower Trapezius, And Serratus Anterior Muscle Activity During Traditional And Modified Muscle Testing Positions, Jace Everett, Mike Fowler, Jason Haak, Robby Luck

Physical Therapy Scholarly Projects

Purpose: The purpose of this study is to assess the muscle activity of the shoulder joint force couple induced by the upper trapezius, lower trapezius, and serratus anterior to determine if they are more effectively recruited during the traditional exercise position of forward shoulder elevation in 145° of shoulder abduction versus a modified position of shoulder external rotation while in 80° of shoulder abduction and 90° of elbow flexion

Methods: Nine participants took part in this randomized study in which EMG data was collected during 4 exercise trials of 10 repetitions each on the right shoulder. EMG activity was monitored …

Effectiveness Of Pressure Biofeedback In Activation Of Transversus Abdominis During The Abdominal Draw-In Maneuver, Jenni L. Freie, Jan L. Kruse, Amanda M. Kvien, Kimberly M. Rzeszutko

Physical Therapy Scholarly Projects

Study Design: Repeated Measures Design.

Objectives: To compare the recruitment of the transversus abdominis and internal oblique during the performance of the supine abdominal draw-in maneuver with the use of pressure biofeedback and without the use of pressure biofeedback. Muscle recruitment will be measured through the use of surface electromyography (EMG).

Background: Surface EMG reliability and validity is reported for transversus abdominis.

Methods: Thirty-nine healthy subjects of the ages 18 to 54 were tested. The subjects were instructed and performed practice trails of the supine draw-in maneuver with and without pressure biofeedback prior to data collection. EMG muscle activity was …

Balance Comparison Of Open- And Closed-Back Shoes, Tiffany Hemberger, Sara Henderson, Eric Loiland

Physical Therapy Scholarly Projects

A growing number of healthcare professionals have been choosing to wear an open-back shoe rather than a traditional closed-back shoe in the workplace. Healthcare professionals incorporate dynamic balance and quick reactions during direct patient interaction. The purpose of the study was to determine if dynamic balance would be affected in healthcare professionals when wearing open-back shoes versus closed-back shoes.

Thirty-two healthcare professionals or students of healthcare professions (28 females and 4 males) were recruited for this study. Subjects ranged in age from 20 to 62 years (mean age 28.2 years), with the majority being physical therapists or physical therapy students. …

Motion Analysis Of A Back Handspring, Sarah Knoll, Jaclyn Minar, Melissa Moos

Physical Therapy Scholarly Projects

Purpose: The purpose of this study was to analyze the joint angles and segmental motion of gymnasts during a back handspring in a tumbling series. The difference in lower extremity motion of the individual gymnasts with different levels of experience was compared.

Subjects: 13 gymnasts were recruited by gymnastics coaches at Red River Valley Gymnastics. Only subjects with qualifications of being competitive in USA Gymnastics program, varying in levels 5-10, were included. Subjects were required to be able to perform a tumbling series consisting of a round off, a back handspring, and a back tuck-salto on a floor exercise mat …

Role Of Z-Coilª Shoes On Plantar Pressure Forces During Short Distance Walking, Tyler Volle, Michael Rider, Brett Jenks, Benjamin Deubner

Physical Therapy Scholarly Projects

Purpose: The Z-CoiL ® company has marketed a shoe that is advertised to decrease pressure and attenuation of forces on the foot, ankle, and other lower extremity joints. Evidence based studies, however, are lacking in support of this claim. The purpose of this study was to compare the peak pressure distributed onto the bottom of the foot from heel strike to midstance when walking bare foot, using a personal athletic shoe, and using a Z-CoiL ® shoe.

Subjects: Thirty subjects without any current history of orthopedic pathologies were examined in this study. Fourteen subjects were excluded from final data analysis, …

Lumbar Spine Extension Mobility Increases With Longer Participation In Football, Matthew Linback, Nicole Nord, Kari Pedersen

Physical Therapy Scholarly Projects

Purpose: Football players are known to develop lumbar spine pathologies, especially extension pathologies (Le., spondylolysis and spondylolisthesis). This study examined the possibility of increased mobility in the lumbar spine with increased exposure to football, possible correlating the increased motion with lumbar spine pathologies. Extension of the lumbar spine in college football players was measured and the results of two groups were compared: those who had completed one or two years of eligibility versus those who had completed three or four years. The influence of the collision nature of football on lumbar extension was examined.

Subjects: Thirty-nine male collegiate football players …

Muscle Activation During Simulated Patient Transfers: Preliminary Study Of Experienced Versus Novice Patient Handlers, Benjamin Mitchell, Patrick Septon

Physical Therapy Scholarly Projects

Purpose: Back injuries are a common problem in providing health care and manually transferring patients can be a cause of back injuries. Because of this fact, there has been a need for research looking into safe methods for manually transferring patients. The intent of this study was to compare muscle recruitment patterns of novice and experienced health care professionals during a simulated patient transfer. By comparing the muscle activity of the experienced group to that of the novice group, we hoped to see differences that could be used to refine training techniques, thus increasing the safety of novice health care …

Eating Disorder Programming In Four-Year College Recreation Wellness Centers, Tiffany Jean Anderson, Amanda Lynn Gulka

Physical Therapy Scholarly Projects

Eating disorders are more prevalent in the college-age group when compared to the lifetime prevalence. Because of this increased prevalence, college recreation/wellness center staff should be aware of their clients in terms of the increased risk for eating disorders. College wellness/recreation centers, while serving the campus community, also serve the individuals within this community diagnosed with or at-risk for an eating disorder. Through survey research, we show who is employed at wellness/recreation centers, what type of training they receive regarding eating disorder, how this training is provided along with its content, and what method of public awareness on eating disorders …
