Health risks to fire fighters.

Fire fighters work in varied and dangerous environments and face unique health hazards that increase their risk for line-of-duty injury and death. While working with sophisticated equipment within such environments, the fire fighter is exposed to high noise levels, changing thermal conditions, and hazardous breathing atmospheres. In addition, his or her protective equipment can impose limitations on efficiency and performance. These conditions have been related to specific physical performance requirements that will reduce line-of-duty injury, disability, and even death. Physical fitness and health maintenance programs that reduce the risk for cardiovascular disease and musculoskeletal injuries have been prescribed for fire fighters. These programs are essential components of any modern fire service.

Psychometric assessment of psychologic factors influencing adult burn rehabilitation.

This article describes psychometric assessment instruments that are available for the screening of psychosocial problems that can interfere with patient rehabilitation. Structured assessment of patient depression, anxiety, substance abuse, social support, and willingness to take control and responsibility for health care is important throughout all stages of the patient's treatment. There are psychometrically sound, relatively brief, and nonintrusive measures with which to assess these variables. The hope is that the early and accurate identification of those patients who are in need of psychosocial services can lead to the implementation of services that will ameliorate psychosocial problems and facilitate total patient rehabilitation. Although many excellent measures exist, the most important assessment tool for the screening of psychosocial problems in patients with burns, which has emerged from this review, is the Psychological Adjustment to Illness Scale (PAIS). The PAIS integrates many of the relevant characteristics of psychologic screening and provides normative values that are specific to patients with burns. Ideally, this scale should be supplemented by an assessment of post-traumatic stress disorder, substance abuse, and personality and coping styles, because these critical factors are not adequately covered by the PAIS. Finally, the Burn Specific Health Scale shows promise for the assessment of health status and quality of life in patients with burns. Future clinical research will hopefully compare and contrast the efficacy and relevance of these measures. Furthermore, future clinical evaluation and research will need to relate the influence of psychosocial factors on the patient's total health functioning. Structured psychometric evaluation of the psychosocial and health characteristics will ensure that patients who have been burned will attain the most fulfilling quality of life that is available to them.

Computer analysis of the performance of the BTE Work Simulator.

The BTE Work Simulator (Baltimore, Therapeutic Equipment Co., Hanover, Md.) recreates the work environment by providing a rotatable shaft to which a variety of tools can be attached. The patient can simulate the coordinated muscle and joint movements involved in the work situation, exercising either isometrically or isotonically, and thereby increase the potential for return to work. The BTE Work Simulator has four major components: the exercise head to provide variable resistance, tools that attach to the exercise head, a control console containing a microprocessor that calculates work and power, and the Quest software package (Baltimore Therapeutic Equipment Co.). Quest provides four static/isometric and seven dynamic/isotonic tests that can be used to document the extent of a patient's impairment. In addition, it has daily treatment options and acts as an extensive data base capable of retrieving any stored test or treatment results. This software system greatly facilitates the use of the BTE Work Simulator by providing instant calculations of power and coefficients of variation, immediate patient feedback, graphic expansion of the data, and printed evaluation reports.

An overview of muscle strengthening.

This article gives an overview of muscle strengthening. In this review, we explore the underlying rationale, the process, and the physiologic adjustments that occur as muscles are trained to become stronger. Although controversy surrounds methods used to strengthen muscles, most agree that regular strength training exercises, regardless of the type, can be beneficial.

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.
