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 …

Effect Of Instruction On Emg Activity Of The Rectus Abdominis During A Crunch On A Swiss Exercise Ball, Tina J. Boyer, Suzanne S. Hammer, Tyler L. Jepson, Eric G. Thompson

Physical Therapy Scholarly Projects

Purpose: The purpose of this study was to assess the benefit of instruction from a physical therapist in participant performance of an abdominal crunch on a Swiss ball, determined through electromyography (EMG) of the rectus abdominis.

Subjects: Our subjects included male (n=15) and female (n=15) college students between the ages of 18-50 years old. Exclusion criteria included a history of low back pain, prior spine surgery, pregnancy, previous formal instruction of crunches on a Swiss ball, and an allergic reaction to rubbing alcohol. Instrumentation: EMG biofeedback was used to test rectus abdominis muscle activity. This activity was transmitted by a …

Emg And Motion Analysis Of Swiss Ball Abdominal Exercises And Pilates Multi-Chair Exercises, Kelly L. Almquist, Ember M. Bopp, Chet R. Yoder

Physical Therapy Scholarly Projects

As the second most common reason for visits to primary care doctors, and a symptom that affects 80% of the general United States population, low back pain and its' treatment is a burdening cost on the American economy every year. Various spinal stabilization exercises have emerged as a means to treat low back pain. One of the most recent fonns of these stabilization exercises used in the physical therapy arena is Pilates, a fonn of dynamic spinal stabilization. Although numerous electromyographic (EMG) studies have been completed on abdominal exercises for spinal stabilization, minimal scientific research can be found on the …

An Electromyographic Analysis Of The Abdominal Musculature In The Production Of Vocalization Intensity During Singing, Chris Huravitch, Nyle Relay, Kristine Schulte

Physical Therapy Scholarly Projects

The purpose of this study was to determine if a relationship existed between electromyographical (EMG) activity in the abdominal muscles and the intensity of sound production. Currently, no consensus existsin the music profession regarding the appropriate use of the abdominal muscles during singing, even though it is known that the abdominal muscles playa significant role in sound production. As musicians strive to improve performance and therapists work to rehabilitate musicians and others who suffer from vocal deficits, understanding the basic muscular requirements of this activity/profession is essential to affect positive outcomes.

Eleven subjects with choral experience were recruited from the …

A Comparison Of Abdominal Muscle Activity During The Crunch, Crunch On Ball, And Abslide Exercises, Jessica M. Norton, Lesley Splonskowski, Hayley Strauss, Sabrina Wagner

Physical Therapy Scholarly Projects

People have developed an obsession with flattening their stomachs and slimming down their waistlines. The so called "ab machines" have become the most popularly purchased home exercise tools. Although numerous electromyographic (EMG) analysis studies have been done on various forms of equipment-free abdominal exercise, little research has been done to evaluate the effectiveness of equipment-aided exercise. The purpose of this study was to analyze and evaluate any differences in EMG activity between three abdominal exercises: the traditional crunch, the crunch on a ball, and utilization of a prone rolling machine (AbSlide®).

Thirty, healthy subjects between the ages of 19 and …

An Electromyographic Study Of Trunk Muscle Activity During Exercise On The Fitness Plus Abdominal Unit, Michelle M. Baumgartner

Physical Therapy Scholarly Projects

Strengthening of trunk musculature is an important part of prevention and treatment for low back pain. Various exercise machines have been developed to strengthen the trunk muscles. One such machine, the Abdominal Unit, has been marketed by a company in North Dakota, Fitness Plus, Inc. However, there is currently no research to validate the manufacturer's claims as to muscles exercised through the use of their machine.

The purpose of this study was to measure and describe the muscle activity elicited while exercising on the Fitness Plus Abdominal Unit. Telemetried electromyography was used to study muscle activity in the rectus abdominis, …
