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 …

Emg Analysis Of Lower Extremity Muscle Activity During Wall Slides With Varying Foot Positions, Jon Beach, Neil Feist, Mike Hiscock, Ryan Stromme

Physical Therapy Scholarly Projects

Knee injuries are among the most common injuries seen in a physical therapy clinic. Nearly all rehabilitation programs following a knee injury involve quadriceps muscle strengthening. One popular and safe method of quadriceps strengthening often used is the wall slide. There is, however, debate and little research indicating whether or not changing the foot position used during wall slides alters the muscle activity during this exercise.

The purpose of this study was to provide a better understanding of the muscle activity during wall slides with feet in various positions so that more accurate rehabilitation protocols may be developed in the …

The Effects A Total Knee Arthroplasty Has On Static And Dynamic Balance, Connie Christensen, Nicole Riddle, Nicole Sukut, Cara Uyema

Physical Therapy Scholarly Projects

In the United States today, the total knee arthroplasty (TKA) has become one of the most commonly performed surgeries of the lower extremity. A generous amount of information exists regarding joint proprioception after a joint replacement, however no studies have been done testing postural control after a TKA. With the increasing popularity of the TKA procedure, a need appears for research evaluating static stability and functional mobility of TKAs.

The purpose of this study was to determine the effects a TKA, 6 months postoperative or beyond, has on static and dynamic balance. The balance of 8 female volunteers and 4 …

An Electromyographic And Motion Analysis Of Forward And Backward Walking, Sarah Dekrey, Lori Guderian, Kerry Hendricksen, Glenda Scott

Physical Therapy Scholarly Projects

Backward walking is a common intervention in the rehabilitation of lower extremity injuries. Despite its popularity, there is limited research available on the EMG activity during backward walking at an incline when compared to forward walking. In this study, we recorded EMG activity in four muscles of the lower extremity and utilized motion analysis to evaluate the knee range of motion when walking forward and backward on a treadmill at 0 and 15 percent grade inclines.

Overall, our results indicated a greater increase in muscle activity during backward walking than forward walking. Walking backward at a 15 percent grade incline …

University Of North Dakota Physical Therapy Alumni Preferences For A Transitional Doctorate Of Physical Therapy Degree, Nolan Lubarski, Jessica Mcdougall, Steven Panos, Heidi Sites

Physical Therapy Scholarly Projects

The purposes of this study are to assess whether University of North Dakota Physical Therapy (UND-PT) graduates desire a transitional Doctorate of Physical Therapy (t-DPT) degree and to determine their preferences regarding this proposed educational program.

The survey was sent to 1136 alumni of the UND-PT program spanning from its first graduating class in 1970 to the class of 2002. It consisted of 8 demographic questions and 12 questions regarding areas such as curriculum content, program implementation, and personal views about the Doctorate of Physical Therapy degree. Frequencies for all responses were determined. The respondent data were also analyzed for …

Electromyographic And Motion Analysis Of The Trunk And Lower Extremity Muscle Recruitment Comparing A Maximal Voluntary Contraction To The Plyo Press And Agaton Max Series Leg Press, Lee Nagle, Thayne Bosh, Tonya Kunze, Kelly Jorschumb

Physical Therapy Scholarly Projects

Numerous studies have been done on the Plyo Press, with focus on the concentric phase of the exercise. However, for athletes eccentric training has always been a topic of interest. Most leg press machines have a concentric and an eccentric phase involved with the exercise. However, during the eccentric phase of the leg press the muscles are underloaded because of the force-velocity relationship of the human skeletal muscle and the fact that eccentric contractions require fewer motor units for the same force and workload. This means that the leg press exercise is limited by the concentric phase. A new machine …

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 …

The Effects Of Partial Body Weight Support For Gait In Patients With Neurological Dysfunction: A Case Study Approach, Sarah Hammers, Alecia Herring, Amanda Olson, Mandy Runyan

Physical Therapy Scholarly Projects

Cerebrovascular accident (CV A) is the primary cause of disability in the United States. l It is estimated that 75% of those who have a CVA survive and function with multiple degrees of impairments. These impairments impact their activities of daily living in a variety of ways. One of the goals of rehabilitation is to minimize the negative effects a CVA has on the functioning of an individual and allow each person to reach his or her maximum potential. Limited research has been conducted exploring the positive outcomes of partial body weight support treadmill training (PBWSTT) in those who have …

The Effects Of Partial Body Weight Support For Gait For Patients With Neurological Dysfunction: A Case Study Approach, Larae Haas, Beth Millage, Becky Sorenson

Physical Therapy Scholarly Projects

The purpose of this study was to determine the effects of partial body weight support during gait for individuals with neurological dysfunction. Body weight support (BWS) training provides a safe environment in which the individual can perform and practice mechanics of normal gait at a variety of speeds with or without body weight support, depending on the level of function. The subjects who participated in this study were community ambulators older than 20 years of age with a neurological diagnosis. Each subject was tested initially and at the conclusion of the study to compare data using a battery of balance …
