Preventing or minimizing functional dependency in older adults rests, in part, upon the ability to predict who is at risk. The purpose of this study was to compare the ability of five tests of hand function to discriminate the degree of dependency in older adults. Seven hundred sixty four subjects were assessed for hand function on performance-based(More)
Nerve conduction velocities (NCV) of the median motor, median sensory, peroneal motor, and sural nerves were measured on 40 lead-exposed automobile production workers as part of a comprehensive health survey. Blood lead (Pb-B) and blood zinc protoporphyrin (ZPP) were measured. The control group (N = 31) consisted of workers without lead exposure. All(More)
The association between lead absorption and objective psychological performance tests in five groups with different levels of lead absorption was studied in the following groups: (1) a control, non-lead-exposed group; (2) cable splicers, (3) cable manufactures, and (4) secondary lead smelter workers. The following performance tests were used: Block Design,(More)
OBJECTIVE To determine factors that predict decline in manual performance using a multivariate model of determinants of functional limitation. DESIGN Longitudinal observational study. SETTINGS Ambulatory general medicine clinics, residences of homebound individuals, and a continuing care retirement community. PARTICIPANTS Subjects were 485 persons(More)
OBJECTIVE To validate a hierarchical model of hand function in older persons, using longitudinal data. DESIGN Longitudinal observational study (2-year data from an ongoing longitudinal study). SUBJECTS 689 persons older than age 60, including Continuing Care Retirement Community (n = 230), homebound (n = 204), and ambulatory (n = 255) respondents. Mean(More)
A comparison of 140 male myopes and 118 male nonmyopes of the entering class of Virginia Military Institute cadets in 1968 demonstrated that there are a number of Strong Vocational Interest Inventory test items which will clearly differentiate myopes from nonmyopes so that it is possible to identify 76% of the individuals falling into either class on the(More)
Nerve conduction velocity (NCV) of the median motor, median sensory, and sural nerves was assessed in 16 workers chronically exposed to various inorganic mercury compounds. Exposed workers were compared with an unexposed control group using t test analyses. Slowing of the median motor nerve NCV was found, which was correlated with both increased levels of(More)
OBJECTIVE To determine factors that predict change in walking velocity in older people using a multivariate model. DESIGN Longitudinal observational study. SUBJECTS A total of 588 persons older than age 60, including subjects residing in a continuing care retirement community (CCRC) (n = 248), and homebound (n = 79) and ambulatory (n = 261) subjects.(More)
