[Work capacity and re-entry into the workforce for the cardiac patient].

BACKGROUND: Treatment and rehabilitation of patients with heart disease is focused on survival, work resumption, achievement of a state of subjective well-being and compliance with behavioural changes in order to prevent progression of the atherosclerotic process. OBJECTIVES: To propose a specific job fitness evaluation method for workers with heart disease, based on analysis of occupational factors influencing the cardiovascular system and the definition of a clinical and functional profile of the patient, with special regard to aspects influencing vocational attitude. METHODS: A literature review was performed. RESULTS AND CONCLUSION: Although resumption of work is not the sole objective in the rehabilitation process, it remains an important goal not only for economic reasons, but also because it is beneficial for most patients' psychological well-being. However, it must be admitted that specific job fitness evaluation is rarely performed during rehabilitation programmes of cardiac patients and this can cause problems at the time of return to work. Doubts and uncertainties are also due to the lack of standardized evaluation methods and to the clinical peculiarity of these patients, mainly due to the risk of sudden disability. The job fitness evaluation method used in this study allows physicians to perform assessments based on objective data, so improving patients' confidence in their work capacity. To achieve a satisfactory application of the method, close cooperation between the cardiologist and the occupational physician is necessary.

The role of functional capacity evaluation in management of foot and ankle dysfunction.

Both job-specific and comprehensive FCEs can be valuable tools in clinical decision-making for the injured worker with foot and ankle dysfunction; however, FCE is an extremely complex and multifaceted process. There are many considerations when selecting or developing a testing protocol or selecting an FCE provider. A myriad of approaches are commercially available and an even greater variety of homegrown tests exists. Little is known about the reliability and validity of these tests and more research is needed. Comparing functional abilities with functional job demands is a process that can provide objective data regarding the relationship of worker abilities to job demands. Balancing this relationship so that work demands do not exceed worker abilities is extremely important for preventing re-injury or re-exacerbation of work-related injuries.

Cardiovascular responses to dynamic and static effort soon after myocardial infarction. Application to occupational work assessment.

Static and dynamic work involving the arms and the legs was performed by 40 men seven weeks after myocardial infarction. Leg ergometry produced a significantly higher peak work load, systolic blood pressure (BPs), heart rate (HR), and HR X BPs X 10(-2) product (DP) than did arm ergometry: 842 +/- 178 vs 546 +/- 135 kg-m/min, 176 +/- 24 vs 154 +/- 19 mm Hg and 256 +/- 54 vs 219 +/- 48 (SD). Peak heart rates were 145 and 142. Endpoints were primarily muscular and generalized fatigue and dyspnea. Ischemic abnormalities and ventricular ectopy were more frequent with leg ergometry. Sustained forearm lifting elicited higher HR, PBs and DP responses than sustained handgrip contraction: 95 +/- 16 vs 91 +/- 16 beats/min, 162 +/- 18 vs 152 +/- 17 mm Hg and 154 +/- 33 vs 139 +/- 33 (SD). Ischemic ST segment depression and significant ventricuar arrhythmias were infrequent with static effort. Dynamic leg testing is superior to dynamic or static arm testing in assessing the capacity of patients to perform physical work tasks after myocardial infarction.

Women's capacities to perform strenuous work.

The literature was reviewed in an attempt to determine women's capacity to perform work. Although the review uncovered a relatively small amount of work devoted to this topic, the published studies suggest that women have both the physiological capacity to perform hard work and the endurance to complete a full day of hard work. However, the studies also suggest that women have limited capabilities to perform tasks requiring lifting, pushing, and pulling. In studies involving climbing and gripping, occupational comparisons were not available. On anthropometric measures the data will not be comparable with work data until occupational information is developed.

[Importance of electroimpulse therapy for restoration of work capacity in patients with auricular fibrillation].

Social rehabilitation was studied in 799 patients with atrial fibrillation. Before the sinus rhythm was restored 26% of the patients had been working. Among the working patients the history of atrial fibrillation was usually of a short duration (9.8 +/- 1 months, on the average), and among the nonworking patients it comprised 28.9 +/- 0.6 months. After the reestablishment of the sinus rhythm the precentage of rehabilitation grew to 40. It greatly depended on the nature of the underlying pathology, sex (among the working patients, 51.8% were men and 25.5% -- women), place of habitation (capacity for work was restored in 45.8% of urban patients, and in 32.0% of rural patients). Upon the restoration of the sinus rhythm the capacity for work increased most markedly among the patients previously subjected to surgical correction of mitral stenosis (by 26.3%), and among those with post-myocarditis cardiosclerosis (by 17.4%). Repeated counterpulsation procedures in cases of atrial fibrillation recurrences provided for a lasting maintenance of the patients' capacity for work. To prolong the rehabilitation results it is rational to recommend such jobs for the patients that would not entail important physical and emotional stress.

[Use of new high-protein products in nutrition for the purpose of increasing the work capacity of students].

The effect of a dietary that includes new high-protein products containing complete protein, on the health status and performance capacity of schoolchildren during their school-hours was studied. Under observation were kept 60 schoolchildren, aged 13-14 years who were learning two foreign languages. Schoolchildren receiving a specialized ration were noted to show a number of positive regular changes. Their physical state, clinico-physiological characteristics and the functional state of the central nervous system demonstrated a definite improvement.

Occupational assessment: the Activity Matching Ability System (AMAS).

This paper describes a new scheme of assessment originally developed to help standardize return-to-work procedures for disabled steel workers. Two compatible techniques of assessment were designed which itemize 100 work demands and the functional abilities of disabled employees to perform these on a simple, ordinal scale. The techniques were evaluated in terms of face and content validity, the inter-rater agreement for coding job demands and the compatibility between levels of item for 55 disabled subjects and their existing jobs. Further reliability testing is in progress; then the efficacy of the system will be evaluated.

[Legal questions in ophthalmology after head injuries (author's transl)].

After a short review of the literature the reduction of earning capacity on the common labour market in cases of decrease of fusion, convergence and accommodation caused by head injuries is discussed and percentual values are proposed. Hereby not only the single reduction of one of these functions but also combined occurrence is allowed for and values for the total reduction of earning capacity are considered.

Hypertension and sports activities: institutional experience.

Findings of 185 patients and 271 control subjects are presented for the assessment of work capacity in hypertensive individuals (primary hypertension); an attempt at classification by hypertensive stage is seen as an essential presupposition. The subdivision into three stages recommended by the Experts' Commission of the WHO places the effects of hypertension on the organism, especially on the heart, in the focal point. This appears justified from a prognostic, pathophysiological, and therapeutic point of view. Hemodynamics in the examined patients undergo increasing impairment in relation to the stage of hypertension with a decrease in maximum cardiac index and work capacity and an increase in myocardial oxygen requirement. Initially, only the diastolic cardiac function is impaired; however, in advanced stages, the systolic function of the heart is impaired as well. Evaluation of work capacity is usually possible from a cardiac point of view by means of noninvasive echocardiographic and spiroergometric methods. The mass/volume ratio of the left cardiac ventricle and the relationship between left ventricular muscle mass (or volume) and work capacity are especially important. Both experience characteristic changes depending on the stage of hypertension and thus permit precise determination of work capacity, progress controls, and delineation from physiological cardiac hypertrophy (athletic heart).

[Guidelines for the sociomedical assessment of performance in patients suffering from breast cancer].

The following guidelines were developed for the medical assessment services of the German Pension Insurance Federal Institution. Starting from day-to-day practice, criteria and attributes to guide decisions for a systemisation of the sociomedical assessment of performance in breast cancer were compiled. The guidelines aim at standardising the sociomedical assessment of performance and help to make the decision-making process more transparent, e. g., for the assessment of applications for decreased earning capacity benefits. The guidelines summarise typical manifestations of breast cancer and describe the necessary medical information for the sociomedical assessment of performance. Relevant assessment criteria for the medical history, clinical examination, and for diagnostic tests are illustrated. The assessment of the individual's capacity is outlined, taking occupational factors into account. Following the determination of dysfunctions, the remaining abilities and disabilities, respectively, are deduced and compared with occupational demands. Finally, inferences are drawn regarding the occupational capacity of the individual.

[Prognosis of work capacity in the system of rehabilitation of patients with myocardial infarct].

The possibilities of prognosing with regard to the capacity for work within the 1st year of resuming working were studied in the system of rehabilitation of myocardial infarction patients. The prognostic value of several items was determined that characterize the state of the patient prior to his myocardial infarction, the course of the acute phase, and the state in the postinfarction period prior to resuming working. The informativeness of several sets of items was determined along with the relative informativeness of a certain single item, with that of a group of other items known. It was demonstrated that in determining the capacity for work the leading items should be conside
