Purpose: The purpose of this study was first, to determine whether there were differences in the roundhouse kicking leg kinematics performed by highly skilled Muay Thai, Karate and Taekwondo practitioners Methods: Twenty-four highly skilled, muay-thai, karate and taekwondo who all were at least a blackbelt with at least 5 years' experience were chosen. All…

Results The measured temperature and kinematic viscosity of the water are listed in Table 1. Temperature of the water tunnel is measured by thermocouple at the beginning of the experiment. The kinematic viscosity of the water is retrieved from the table of properties of water in Appendix A. Interpolation was used to approximate the most accurate value of the viscosity. Calculation of interpolation is shown in Appendix A. Water Temperature (°C) 16.6 ±0.1 Kinematic Viscosity (m2/sec)…

Wind Energy and Dynamics Today many forms of energy exist that assist in creating power to be used on the industrial and commercial level, as well as power the many buildings that reside throughout the United States and the rest of the world. While there are an immense amount of methods that produce power/energy, one of the more recent developments pertains to that of wind energy. Wind energy is considered a renewable energy source because wind is always in supply, whereas fossil fuels such as…

Common symptoms of the full can and empty can test are weakness and pain, therefore both tests need to be used to test for rotator cuff injuries. If pain, weakness, or both are present, these tests are thought to be positive. Since pain modifies muscle strength, there is a concern about the reliability of the empty can test.1 This concern arises because of the internal rotation of the humerus results in impingement, therefore potentially decreases the usefulness of the test. With the empty can…

starting the exercise, participants walked on the treadmill at a self-selected pace for 5 minutes as a warm-up. The researchers selected a comfortable jogging pace for all the participants, regardless of the current activity level and collected kinematic and kinetic data while the subject jogged on the treadmill. To ensure at least 10 full gait cycles were recorded during each trial, three 15 second trials were collected. In each condition, group mean values of…

by the last 3 out of an upright posture. All participants were required to have hands by their given angles and center of mass height. The positioning of hands were of importance because it helped to keep subjects in their appropriate position. Kinematic data was retrieved by using a Pro-Reflex Motion Analysis System at 240-Hz. Ground Reaction Force (GRF) was analyzed by a force platform at 1200-HZ, and maximum vertical jump was inferred once the subject lost contact with the ground. Reflective…

Robotics is one of the young fields of modern technology that has crossed the limits of traditional engineering.[1] Understanding of robots requires knowledge from a very vast domain including mechanical engineering, electrical engineering, systems and industrial engineering, economics, computer science and mathematics. Manufacturing engineering, knowledge engineering and applications engineering are some of the new fields which are emerging rapidly to deal with the complexity of robotics and…

Patients who recover from chronic stroke and other brain-related problems such as surgery on brain cancer tend to lose balance and gait abilities. This includes involuntary movements of some voluntary muscles in parts of the body. Lack of Coordination between the brain and the muscles when impaired lead to the involuntary muscular movement, a condition that affects many post-stroke patients. There have been a number of mechanisms to help post-stroke patients continue with their usual activities…

Advanced ankle arthritis, avascular osteonecrosis (AVN), and osteomyelitis (OM) of the ankle remain a surgical challenge in the foot and ankle arena with limited treatment options (64,62,61,52,42). The role of the talus within the ankle joint is of particular interest as it guides sagittal motion of the lower extremity (22). Multiple medical comorbidities including but not limited to autoimmune disease, trauma, avascular necrosis (42,52-54), or other idiopathic etiologies contribute to total…

to patients without shoulder dysfunction. When I treat a shoulder pain patient, I always evaluate and treated cervical, cervico-thoracic junction, and thoracic segments. The relationship between thoracic spine posture, shoulder ROM, and scap¬ular kinematics is well described in the literature. Lewis et al. (1) found that altering posture in patients with musculoskeletal shoulder pain improves pain free range-of-motion (ROM) during shoulder elevation. Two studies have specifically as¬sessed the…
