“…However, Newham and Hsiao (2001) did observe increased strength throughout the first half year after stroke, while activation failure remained constant. Andrews et al (2003) showed an increase in both PL and NL knee extensor strength from admission (~2 wk post stroke) to discharge (~4 wk post stroke). So, there are no consistent data indicating that muscle variables improve after stroke.…”

“…For each brain, we identified the age, volume (in mm 3 ), side, and location of all cerebral infarcts visible to the naked eye as previously reported. 19 For these analyses, we included all old cortical and subcortical gray and white matter cerebral, cerebellar, and brainstem infarcts.…”

Objective: We examined the extent to which physical frailty in older persons is associated with common age-related brain pathology, including cerebral infarcts, Lewy body pathology, and Alzheimer disease (AD) pathology. Methods:We studied brain autopsies from 165 deceased participants from the Rush Memory and Aging Project, a longitudinal clinical-pathologic study of aging. Physical frailty, based on four components, including grip strength, time to walk 8 feet, body composition, and fatigue, was assessed at annual clinical evaluations. Multiple regression analyses were used to examine the relation of postmortem neuropathologic findings to frailty proximate to death, controlling for age, sex, and education. Results:The mean age at death was 88.1 years (SD ϭ 5.7 years). The level of AD pathology was associated with frailty proximate to death (␤ ϭ 0.252, SE ϭ 0.077, p ϭ 0.001), accounting for 4% of the variance of physical frailty. Neither cerebral infarcts (␤ ϭ Ϫ0.121, SE ϭ 0.115, p ϭ 0.294) nor Lewy body disease pathology (␤ ϭ 0.07, SE ϭ 0.156, p ϭ 0.678) was associated with frailty. These associations were unchanged after controlling for the time interval from last clinical evaluation to autopsy. The association of AD pathology with frailty did not differ by the presence of dementia, and this association was unchanged even after considering potential confounders, including physical activity; parkinsonian signs; pulmonary function; or history of chronic diseases, including vascular risk factors, vascular disease burden, falls, joint pain, or use of antipsychotic or antihypertensive medications. Physical frailty is common in the elderly and associated with adverse health outcomes, but its underlying biology is poorly understood. Although frailty is a heterogeneous syndrome, a number of features, including strength, gait, body composition, and fatigue, are generally accepted as core components of physical frailty. Conclusion:1,2 Cerebral infarcts and Lewy body disease are known to be associated with impaired physical performance.3,4 Furthermore, recent work by several groups suggests that several core components of frailty, including impaired grip strength, slowed gait, and low body mass index (BMI), predict subsequent development of dementia.5-7 These reports suggest that common brain pathology may contribute to physical frailty in the elderly.We used data from the Rush Memory and Aging Project, 8 a longitudinal epidemiologic clinical-pathologic study of chronic conditions of aging, to examine to what extent common

“…Six studies (20%) reported that the demonstration procedures were carried out and used verbal instructions (15,28,31,37,40,44) and two studies used movement instructions (15,44). Six studies (20%) (15,30,35,37,39,44) reported the familiarization procedures with the participants performing the same test procedures, prior to data collection. Of the 30 included studies, which investigated the measurement properties of portable dynamometry for the assessment of strength in subjects with stroke,…”

Introduction: Weakness of the lower limb muscles, which are the main impairments after stroke, is associated with reduced mobility and decreased performance in functional tasks. Therefore, the assessment of strength of these muscles is necessary, which is commonly assessed with portable dynamometry. Aims: To perform a literature review regarding the methods used to assess lower limb strength with portable dynamometry in subjects with stroke and to describe its investigated measurement properties with this population. Materials and Methods: An extensive search was performed on the MEDLINE, SCIELO, LILACS, and PEDro databases, by combining specific key words, followed by active manual search by two independent researchers. Results and Discussion: Thirty studies were included, and the muscular groups of the knee (90%) were the most assessed, followed by the ankle (66.7%) and hip (63.3%) joints. In 5% of the studies, there were not reported any descriptions related to the positioning of the subjects and the equipment, neither regarding the stabilization procedures. Only 50% provided information regarding the number of trials and only 46.7% regarding the contraction times, being three trials and 5s the most commonly applied. Only 10% provided feedback and 23.3% demonstrations, prior to data collection. Only seven studies (23.3%) investigated the measurement properties of portable dynamometry and reported moderate to high reliability levels. Final Considerations: The protocols used for the assessment of the strength of the lower limb muscles with portable dynamometry in subjects with stroke were not standardized. Moreover, only one measurement property was investigated: the reliability, which was considered adequate.
