BACKGROUND: A comprehensive surveillance system for occupational injuries to adolescents does not exist in Texas, as in most states. Therefore, the magnitude, severity, nature, and source of injuries to working adolescents have not been well described in Texas. METHODS: The investigators used three data sources to investigate work-related injuries and deaths in Texas: (1) Texas Workers' Compensation Commission (TWCC) claims data from 1991 through April 1996; (2) 1993 TWCC/Bureau of Labor Statistics (BLS) Annual Survey of Occupational Injuries and Illnesses; and (3) work-related fatalities identified from Texas death certificates from 1990-1995. RESULTS: There were 9,027 injuries reported to the TWCC for adolescents 14-17 years of age during slightly more than 5 years. Injuries for which indemnity payments were made (more than 7 days out of work) occurred among 21.7% of the adolescents. Based on BLS data in 1993, of 992 non-fatal injuries involving days away from work, 35% were caused by contact with objects, 27% by bodily reaction, and 24% by falls. Two-thirds of these injuries occurred while working in eating and drinking places and grocery stores. Three-quarters of the 30 deaths from 1990-1995 were accounted for equally by motor vehicle and homicide. CONCLUSIONS: In conclusion, a substantial number of adolescents are injured or killed in the workplace each year in Texas. Although improved population-based surveillance is needed, sufficient knowledge exists to begin prevention efforts now.
BACKGROUND: Home health services represent one of the fastest-growing segments of the US economy. Home health care workers (HHCWs) might be expected to have a high incidence and increased severity of injury because of inherent difficulty in control over their work environment, and the limited amount of research on injuries in home health care appears to support this hypothesis. METHODS: Using data on workers' compensation claims for 1995-1996 from a large state database, we calculated the incidence, frequency, and types of injuries occurring in this working population. Comparison data were drawn from nursing home (NH) and hospital-based nursing personnel. RESULTS: An incidence of 52 injuries per 1,000 workers per year was calculated; this rate lies between nursing home workers (132/1,000) and hospital-based workers (46/1,000). The percentage of indemnified (> 3 days lost-time) injuries was increased over those occurring in nursing home personnel. Mean number of days lost from work by home health workers was 44, significantly increased from the average 18 and 14 days lost by NH and hospital nursing workers, respectively. Mean indemnity payment was $1,523 and mean medical costs were $1,276 per injury. Permanent partial disability awards were made to 19 (4.9%) of the injured HHCWs during the 2-year study period; back injuries accounted for 63% (12) of these awards. Overexertion injuries and falls accounted for 63% of total injuries in this group of workers, while 13.5% occurred as a result of motor vehicle accidents. The incidence of injury attributed to motor vehicles in HHCWs was 7 per 1,000 workers per year, an order of magnitude greater than in NH and hospital workers. CONCLUSIONS: These data indicate that injuries to HHCWs, though less frequent than in their nursing home counterparts, result in greater lost time from work and accompanying costs, which may indicate greater severity of injury. Characteristics of home health work, including increased intensity and speed of work, adverse working conditions, and the necessity of motor vehicle transportation as a condition of work may be contributors to injury in this setting. Further investigation of determinants of accidents and injuries in home health care, both in the actual setting where the work takes place and in the way it is structured, is warranted.
Most neurologists are familiar with biomechanics but may be unsure of the relevance of this field to their practice. Actually those involved in musculoskeletal problems are undoubtedly using biomechanical principles. This article is limited to the spine, but the basic principles of biomechanics are applicable to other parts of the body. In this article, we describe the spine and trunk as a biomechanical organ, the biomechanical principles behind back injuries and their importance, the role of biomechanical issues in pain, the utility of clinical tests based on biomechanical principles, the effects of aging, and the future directions in spine biomechanical research.
