Musculoskeletal rehabilitation and sports medicine. 4. Miscellaneous sports medicine topics.

This self-directed learning module highlights new advances in this topic area. It is part of the chapter on musculoskeletal rehabilitation and sports medicine in the Self-Directed Physiatric Education Program for practitioners and trainees in physical medicine and rehabilitation. This article discusses physiatric duties as a team physician, preparticipation physical examinations, ergogenic aids, heat-related illness, pediatric sports injuries, female sports injuries, and sports medicine topics pertinent to geriatric and physically or mentally challenged athletes. New advances covered in this section include use of creatine, guidelines for the preparticipation examination, sudden cardiac athletic death, pediatric and female anterior cruciate ligament injuries, the female athlete triad, spine screening in Down syndrome athletes, and "boosting" in athletes with spinal cord injury.

Pricing behavior of non-profit agencies. The case of blood products.

In this study we examine the pricing behavior of a non-profit agency, the American National Red Cross blood service units. Two alternative hypotheses are presented: one in which the agency maximizes profits,, and one in which output is maximized subject to a breakeven constraint. Following a general approach developed by Eckstein and Fromm , pricing equations for separate blood products are applied to cross-sectional data from Red Cross blood centers to determine the impact of demand, cost, competition, and subsidy variables. The impact of these variables, in particular the impact of the fixed subsidy on price, is shown to be consistent with the output-maximizing model.

Evaluation of cohesive and elastic support bandages for joint immobilization.

The purpose of this clinical study was to compare the performance of a new cohesive bandage to that of elastic bandages for joint immobilization. The magnitude of joint immobilization by these bandages was quantitated during isokinetic exercise using a computerized dynamometer. The degree to which the cohesive and elastic bandages reduced range of motion and peak torque of plantar and dorsiflexion was not significantly different. After exercising for 1 hour, the elastic bandage loosens, reducing its ability to immobilize the joint. In contrast, the cohesive bandage maintains its configuration, despite active exercise for 1 hour.

A standard measure for exercise prescription for aqua running.

Aqua running has been promoted as a method for cardiovascular conditioning for the injured athlete as well as for others who desire a low impact aerobic workout. Recent studies have suggested the need for an environment-specific measure of exercise intensity. Twenty healthy subjects, 10 men and 10 women, underwent a graded exercise test of aqua running to investigate the relationship between cadence and heart rate. This was done to determine the utility of cadence as a measure for exercise prescription. The graded exercise test followed a standard protocol for exercise testing in aqua running. Results demonstrated a high correlation between cadence and heart rate, both as a group as well as individually. We conclude that cadence may be used as a measure for exercise prescription for aqua running.

A new hydrofitness device for leg musculoskeletal conditioning.

A new leg hydrofitness device has been designed for aquatic exercise. It consists of three separate rectangular-shaped buoyant floats that are positioned around the ankle. A clinical trial indicates its potential value for walking reeducation, strengthening leg muscles, and enhancing joint extensibility.

A new porous cohesive support bandage.

A new support bandage has been developed that is cohesive, sticking only to itself without adhering to the skin. It is warpknit product, impregnated with an acrylic compound, that consists of individual panels connected by a hinge stitch. It exhibits moderate extensibility under low loads which allows the health professional to apply the bandage so that it gives firm support to the underlying tissue without constriction. Its macroporous structure permits sufficient water vapor transmission to allow the underlying skin and/or wound to remain dry.

Bioengineering principles of hydrotherapy.

Hydrotherapy is based on several important bioengineering principles that permit the design and development of aquatic exercise devices, techniques and programs. These principles involve several forces (buoyancy, drag, inertia), hydrostatic pressure and the specific heat of water. By acquiring a knowledge of these bioengineering principles, an individualized exercise program can be prescribed that will enhance physical fitness which is associated with desirable psychological changes.
