“…one aspect of physical condition or capacity), while COP parameters from a force platform can directly analyze balance deficits (postural adjustments and responses, postural stability limits, ability to recovery the balance) 5,13,[21][22][23][24] . The values found in the present study for both functional test performance time and force platform balance parameters agree with other studies 5,17,25,[36][37][38] despite their different protocols and purposes. In general, physical (Tlimit, Tshorstest) and balance (COP parameters) performance in elderly can be associated with the aging process from muscular weakness, lack of mobility, sensory-motor deficits 3,8 .…”

“…Fregly et al 17 performed a battery of ataxia tests with 1,055 men, aged 16 to 60 years, who were healthy. The tests included eyes-open and eyesclosed standing and walking heel-totoe on a 3 ⁄ 4-in (1.9-cm) rail, single-leg stance on the floor, and Sharpened Romberg test.…”

Background and Purpose The Functional Gait Assessment (FGA) is a clinical tool for evaluating performance in walking. The purpose of this study was to determine age-referenced norms for performance on the FGA in community-living older adults. Subjects Subjects were 200 adults, ages 40 to 89 years, living independently. Methods Each subject completed the FGA one time and was scored simultaneously by 2 testers. Results The intraclass correlation coefficient for interrater reliability was .93. Mean scores for the FGA ranged from 29/30 for adults in their 40s to 21/30 for adults in their 80s. Discussion and Conclusion Patient performance on the FGA can be compared with age-referenced norms for expected performance. Further research is needed to determine the FGA’s usefulness in tracking clinical changes or predicting falls. The FGA is a reliable test for people without disease, and it is able to detect decreases in gait performance among typical older adults.

“…This dysfunction was defined by instability of gait and static posture, which were assessed using the eyes open condition of the Fregly-Graybiel walka-line test (Fregly et al, 1973). Performance on this ataxia test was normalized to age and sex derived from a separate age regression analysis for 108 healthy men and 87 healthy women (data taken from Sullivan et al, 2010).…”

The purpose of this study was to determine whether meeting historical criteria for unsuspected Wernicke's encephalopathy (WE), largely under-diagnosed in vivo, explains why some alcoholics have severe neuropsychological deficits, whereas others, with a similar drinking history, exhibit preserved performance. Demographic, clinical, alcohol related, and neuropsychological measures were collected in 56 abstinent alcoholics and 38 non-alcohol-dependent volunteers. Alcoholics were classified using the clinical criteria established by Caine et al (1997) and validated in their neuropathological study of alcoholic cases. Our alcoholics who met a single criterion were considered 'at risk for WE' and those with two or more criteria with 'signs of WE'. Whole blood thiamine was also measured in 22 of the comparison group and 28 alcoholics. Of the alcoholics examined, 27% met no criteria, 57% were at risk for WE, and 16% had signs of WE. Neuropsychological performance of the alcoholic subgroups was graded, with those meeting zero criteria not differing from controls, those meeting one criterion presenting mild-to-moderate deficits on some of the functional domains, and those meeting two or more criteria having the most severe deficits on each of the domains examined. Thiamine levels were selectively related to memory performance in the alcoholics. Preclinical signs of WE can be diagnosed in vivo, enabling the identification of ostensibly 'uncomplicated' alcoholics who are at risk for neuropsychological complications. The graded effects in neuropsychological performance suggest that the presence of signs of WE explains, at least partially, the heterogeneity of alcoholism-related cognitive and motor deficits.
