Biomechanical Analysis Of The Upper Extremity During Multiple Softball Pitches, Amy Bookkless, Katelyn Bottelberghe, Tara Petersen

Physical Therapy Scholarly Projects

Purpose: There are a large number of fast pitch softball participants including high school, college, Olympic, professional and recreational leagues. While a large number of studies describe the baseball pitch, there is a shortage of studies describing the windmill softball pitch. Therefore, the purpose of this study is to utilize electromyography (EMG) and motion analysis to determine the biomechanical factors of muscle recruitment, shoulder and elbow range of motion and joint velocities during the windmill softball pitch.

Subjects: Five Division II women's fast pitch softball pitchers, mean age 19 years, were included in the study. The player's pitching experience averaged …

Three-Dimensional Kinematics Of The Overarm Throwing Motion In Children Ages 2 To 7, Jacalyn R. Breidenbach

Physical Therapy Scholarly Projects

Background and Purpose: Throwing is a meaningful play activity that encourages social interaction, develops the sequencing of motor skills, and signals the onset oftoddlerhood. Little published data clearly documents the three-dimensional kinematics ofthe progression of the overarm throwing motion in children. The purpose of this study is twofold: 1) To explore the biomechanical differences in the overarm throwing techniques of children between the ages of two and seven, and 2) To compare the kinematics of dominant versus non-dominant arm throws in children between the ages of two and seven.

Methods: 1) Nine children, 6 males and 3 females, were classified …

An Electromyographic And Video Motion Analysis Study Of The Drawback And Hold Phases Of Compound Bow Versus A Traditional Bow In Experienced Archers, Jason Brodina

Physical Therapy Scholarly Projects

Background/Purpose: Archery is quickly becoming an increasingly popular sport, with limited research in the training and rehabilitation of archers. The purpose of this study is to identify the major muscles and timing of recruitment during the drawback and hold of a bow, and to determine the presence of differences in this recruitment between a compound and traditional bow.

Subjects/Methods: Seven males between the ages of 36 to 51 years of age completed 6 drawbacks each with a compound bow and a traditional bow. Surface electrodes on the subjects and reflective markers on the bow were used to analyze electromyographic activity …

A Motion Analysis Study Describing The Kinematics Of The Curling Delivery, Sam Harms

Physical Therapy Scholarly Projects

Background and Purpose: In 1998, curling was awarded medal status in Olympic competition, and since then, the popularity of the sport has dramatically increased. This has led to increased skill level and competition among curlers. However, there is currently limited research analyzing the curling delivery. The purpose of this study is to provide scientific information explaining delivery characteristics of curlers while executing draw and take-out shots. This study concentrated on the force generators within the delivery and the mechanisms used to control and determine weight.

Methods: Three healthy subjects participated in this motion analysis study. Subjects were video taped completing …

An Electromyographic And Video Motion Analysis Study Of Elite Sprinters At Varying Speeds And Inclines, Samantha Gould

Physical Therapy Scholarly Projects

Every athlete trains with the hopes of being bigger, stronger or faster than the competitor. Athletes are eager to jump on the "bandwagon" of new training techniques that claim to produce the results the athlete seeks. One such training technique is sprinting on a treadmill at high speeds and inclines. The purpose of this study is to describe muscle activity and joint motion while running on a treadmill at different speeds and inclines.

Six males between the ages of 21 and 27 years of age ran at 20 miles per hour and 0% grade and at 13 miles per hour …

Subtalar Joint Biomechanics, Tom L. Baumgartner

Physical Therapy Scholarly Projects

Subtalar joint movement is transmitted proximally to the lower extremity and distally to the forefoot during gait. Thus, the entire lower kinetic chain is influenced by abnormal subtalar joint biomechanics. If the subtalar joint is forced to compensate for structural deformities of the foot and leg, various lower extremity injuries are likely to develop. The purpose of this study is to examine the normal and abnormal biomechanics of the subtalar joint. In the process, the clinician will be able to identify various subtalar joint abnormalities and relate these to their respective lower kinetic chain pathologies. By correctly assessing the cause …

The Effects Of Supramalleolar Orthoses On The Biomechanics Of The Knee, Foot, And Ankle During Gait: A Single-Subject Design, Jennifer Ruth Stauffer

Physical Therapy Scholarly Projects

Gait deviations are a common problem associated with disorders of movement and posture such as cerebral palsy (CP). Inhibitive casts and ankle-foot orthoses have been used to treat gait deviations in children with CP, but they have not satisfied the needs of children who are able to achieve active dorsiflexion and plantarflexion but lack stability at the subtalar joint. Supramalleolar orthoses (SMOs) were developed to address that need. SMOs, along with physical therapy, have been used to treat children with CP, but little research has been conducted to determine the actual effects of the SMO on lower extremity biomechanics during …

The Role Of Foot Biomechanics In Lower Extremity Pathologies, Don Martin

Physical Therapy Scholarly Projects

Lower extremity pathologies caused by abnormal biomechanics of the subtalar joint are commonly seen in the health care setting. Certain foot types will predispose an individual to excessive amounts of subtalar joint pronation or supination during gait. Subtalar joint movement is transmitted proximally to the lower extremity during gait and excessive amounts of pronation or supination can lead to altered biomechanics in the lower extremity with development of various lower extremity injuries. The purpose of this study is to analyze the biomechanical events of the subtalar joint of the foot during gait in order to show how abnormalities in these …
