The Effect Of High Velocity Sport Specific Training On Throwing Velocity, Christopher Albrecht, Mandy Caspers, Jennifer Hammond

Physical Therapy Scholarly Projects

Previous studies have shown strength training programs to be effective in improving throwing velocity. The aim of this study was to determine whether there was a significant training effect, as measured by an increase in throwing velocity, among subjects who had been instructed to perform proprioceptive neuromuscular facilitation (PNF) techniques of the dominant upper extremity at a slow and controlled speed, subjects who had been instructed to perform PNF techniques of the dominant upper extremity at a sport specific speed, and a control group. A total of 28 male and female subjects, between the ages of21 and 30 participated in …

Reliability Of Shoulder Goniometric Measurements In Persons Who Are Elderly, Karina Koch, Lauri Paulsen, Heather White, Richard Williamson

Physical Therapy Scholarly Projects

The population of the United States is rapidly aging; this is exemplified by the cohort of "Baby-Boomers" who make up a large part of the population. This becomes relevant to physical therapists, as our clients will reflect this "graying" of America. There is a lack of research regarding normative values for shoulder range of motion (ROM) in the elderly population. Due to many different factors in the aging process, there may be a decline in ROM in elderly persons. Current normative values may not be applicable to this population.

Two pilot studies were conducted measuring active and passive shoulder ROM …

Electromyographic And Motion Analysis Of The Trunk And Pelvis During The Golf Swing, James A. Vranna

Physical Therapy Scholarly Projects

The purpose of this study was to analyze and compare the trunk muscle activity and range of motion in male and female golfers. With the use of surface electrode electromyography and motion analysis, three male and three female Division II collegiate golfers were evaluated. The EMG activity of the erector spinae, gluteus maximus, and external oblique muscles was measured bilaterally during the golf swing. The main emphasis in analyzing the trunk range of motion was comparing relative pelvis to shoulder rotation (X-factor) throughout the swing. The researchers found definitive differences in the patterns of muscle activity and range of motion …

An Emg And Video Analysis Of The Wrist Flexors During A Sidearm Baseball Delivery, Cordell J. Mack

Physical Therapy Scholarly Projects

By understanding proper pitching mechanics, therapists can develop better preventative and rehabilitation programs for pitchers. The purpose of this study was to explain the joint motions and muscle activity that occur at the elbow during both an overhand and sidearm baseball pitching delivery. Three healthy adult pitchers with recreational sidearm pitching experience were examined with synchronized high-speed video digitization and surface electromyography (EMG). It was proposed that the increased valgus moment during the acceleration phase due to the sidearm delivery would subsequently show an increase in EMG activity by the wrist flexor-pronator group to provide additional varus torque in minimizing …
