Q: Abstract: Using a series of graded destabilizing forces, we have developed a simple quantitative test of the postural response: the Postural Stress Test (PST). Suitable for widespread testing of elderly subjects, the test evaluates the subject's ability to avoid a fall as well as the appropriateness of the response. We have determined that by comparison with young subjects, the elderly controls have compromised although functionally effective balance. On the other hand, the balance response was severely compromised in half of the individuals with a history of falls. Experience with the Postural Stress Test suggests it will predict those elderly individuals with a tendency to fall as well as provide a simple mechanism for studying the balance response in the elderly.

Q: Abstract: We describe a patient with hypertrophic osteoarthropathy secondary to regional enteritis, and review the literature on their association. The apparent different distribution of hypertrophic osteoarthropathy secondary to other causes may be artifactual and related to inadequate radiological investigation. Hypertrophic osteoarthropathy does not appear to be related to regional enteritis activity.

Q: Abstract: The New Mexico State Legislature passed a child restraint law applicable to children less than 5 years of age that became effective in June 1983. To evaluate the effectiveness of this law, we analyzed traffic accident data for New Mexico from January 1981 through September 1984. During this period, there were 20,972 children younger than 5 years of age in motor vehicle accidents. Restraint usage increased for this age group from a low of about 10% in 1981 to more than 40% in 1984 (P less than 10(-6)). Unrestrained children younger than 5 years of age were five times more likely to be killed and two times more likely to be injured than restrained children. Analysis of motor vehicle accident fatality and injury rates pre- and post-law revealed a 33% reduction in motor vehicle accident fatality rates and a 12.6% reduction in nonfatal injury rates for children younger than 5 years. We conclude that child restraint devices are effective in reducing motor vehicle accident fatalities and injuries in young children and the child restraint law has been effective in increasing child restraint usage and in reducing childhood death and injury in New Mexico.
