Those measurements were ascertained through the use of skin markers distributed on the lower extremities on subjects with no known histories of knee pathology or symptomatic complaints. After measuring VV and IRER angles in the neutral barefoot position, the researchers made similar measurements of those angles in several ski boot positions, including standing, canted, and rotated positions within the adjustable limitations of the ski boots. They also conducted measurements of simulated loading positions natural to skiing, achieved through the use of an angled platform duplicating the ski slope angle and a weighted pulley system designed to transmit downward forces between the skier and the sloped platform in the same perpendicular angle experienced during actual skiing.
Critical Analysis of Technique Selected:
The technique selected provides an analysis of limited applicability to skiing because it tested only static forces rather than the many dynamic forces (both internal and external) associated with actual skiing. Less significantly, the researchers mentioned additional limitations on the accuracy obtainable through the use of skin markers, which are known to shift slightly, while pointing out that such movement is more of a concern when testing dynamic movements. Finally, local deformation of the ski boot materials under loading complicates the precision of markers measuring forces attributable to ski boot position. This limitation is likely greatly magnified under the dynamic stresses associated with skiing compared to the static loading measurable in the study as designed.
Greater precision would be possible through similar implementation of skin markers on subjects during actual...
Medical Management of Adolescent Athletic Knee Fractures is a 13-year-old middle school student who was admitted to Antelope Valley hospital complaining of severe pain in the right knee while playing football in his Physical Education class at school. As the patient turned to run for a pass, he twisted his right knee and fell to the ground. C.W. reports that he immediately felt a snapping and popping sensation at his right
Among the criteria that should be evaluated in any progressive training program must include the duration and intensity of exercise and they types of exercise to be used (Browder and Darby, 1998). Guidelines for the program with time might include utilization of short-term or high intensity exercises interspersed with lower intensity and longer duration exercises (Browder & Darby, 1998). This suggests alternating strength-training events with cardiovascular endurance activities to maximize
The literature review was finally released in a document called "Scientific Support Documentation for the Revised 1991 NIOSH Lifting Equation: Technical Contract Reports, May 8, 1991." (Applications Manual for the Revised NIOSH Lifting Equation) This is an update and contains information on the physiological, biomechanical, psychophysical, and epidemiological aspects of manual lifting. This led to the recommendation by the ad hoc committee of the criteria for defining the lifting
Dry Needling Cover letter Department of Science Attachment: Over time, dry needling has turned out to be a well-liked therapy method in manual physical rehabilitation (Dommerholt et al., 2006). Physiotherapists as well as other healthcare service providers in numerous nations utilize dry needling within the clinical therapy of individuals with myofascial discomfort and trigger points. Within the U.S.A., roughly 20 states and also the District of Columbia have authorized dry needling by physiotherapists,
). Non-Pharmacological Management of Plantar Fasciitis The ideal management of plantar fasciitis is prevention, which is through appropriate warm-up exercises, quality shoes and exercises at an appropriate training level on a safe surface (Miller 2004). Barrett and O'Malley (1999) recommend a conservative treatment that addresses the inflammatory element causing the discomfort and the biomechanical factors producing the disorder. To complement the treatment, the patient should be adequately educated on the etiology of their
It is evidenced that soon after lapse of two months of treatment about 67% of the patients administered with manual therapy and 27% of the patients administered with exercise therapy could return to work revealing substantial difference through the follow up period. The study concluded that improvements are noticed in both the groups. However, the improvements in respect the patients administered with manual therapy are more prominent than that
