Responsive Measure (responsive + measure)
Selected AbstractsEvaluation of a German version of the Rivermead Mobility Index (RMI) in acute and chronic stroke patientsEUROPEAN JOURNAL OF NEUROLOGY, Issue 5 2000M. R. Schindl The English Rivermead Mobility Index (RMI) has been proposed as a simple, valid and reliable measure in stroke rehabilitation. A German version was established and validated in two centres. In centre A 46 acute (median: 3.0 days after onset) and in centre B 151 chronic (median: 88.0 days after onset) stroke patients participated. Interrater reliability of the German RMI was tested in 12 subjects in the acute stage of stroke and was found to be statistically significant (r = 0.98, P < 0.0001). In centre A, a statistically significant correlation was found between the German RMI and the 10-m walk time at baseline (r = 0.73, P < 0.0001) and after three weeks (r = 0.92, P < 0.0001). In centre B, the German RMI correlated significantly with the motor part of the Functional Independence Measure (motor-FIM) on admission (r = 0.78, P < 0.0001) and after three weeks (r = 0.79, P < 0.0001), respectively. The change of the RMI correlated significantly with the change in 10-m walk time in acute patients (r = 0.87, P < 0.0001) and with the change in motor-FIM in chronic patients (r = 0.54, P < 0.0001). A moderate ceiling-effect was detected in the chronic study population. The German RMI appears to be a reliable, valid and responsive measure for mobility disability in acute and chronic stroke patients.

Hill 1.,Benthic microbial respiration was measured in 214 streams in the Appalachian Mountain, Piedmont, and Coastal Plains regions of the eastern United States in summer 1997 and 1998. 2.,Respiration was measured as both O2 consumption in sealed microcosms and as dehydrogenase activity (DHA) of the sediments contained within the microcosms. 3.,Benthic microbial respiration in streams of the eastern U.S., as O2 consumption, was 0.37 ± 0.03 mg O2 m,2 day,1. Respiration as DHA averaged 1.21 ± 0.08 mg O2 m,2 day,1 4.,No significant differences in O2 consumption or DHA were found among geographical provinces or stream size classes, nor among catchment basins for O2 consumption, but DHA was significantly higher in the other Atlantic (non-Chesapeake Bay) catchment basins. 5.,Canonical correlation analyses generated two environmental axes. The stronger canonical axis (W1) represented a chemical disturbance gradient that was negatively correlated with signatures of anthropogenic impacts (ANC, Cl,, pH, SO42), and positively correlated with riparian canopy cover and stream water dissolved organic carbon concentration (DOC). A weaker canonical axis (W2) was postively correlated with pH, riparian zone agriculture, and stream depth, and negatively correlated with DOC and elevation of the stream. Oxygen consumption was significantly correlated with W2 whereas DHA was significantly correlated with W1. 6.,The strengths of the correlations of DHA with environmental variables, particularly those that are proven indicators of catchment disturbances and with the canonical axis, suggest that DHA is a more responsive measure of benthic microbial activity than is O2 consumption. [source] Quantitative assessment of daytime motor activity provides a responsive measure of functional decline in patients with Huntington's diseaseMOVEMENT DISORDERS, Issue 3 2001J.P.P. van Vugt MD Abstract Voluntary motor impairment is a functionally important aspect of Huntington's disease (HD). Therefore, quantitative assessment of disturbed voluntary movement might be important in follow-up. We investigated the relation between quantitatively assessed daytime motor activity and symptom severity in HD and evaluated whether assessment of daytime motor activity is a responsive measure in the follow-up of patients. Sixty-four consecutive HD patients and 67 age- and sex-matched healthy controls were studied. Daytime motor activity was recorded using a wrist-worn activity monitor that counts all movements during a period of five consecutive days. Patients were rated clinically for voluntary motor impairment, dyskinesias, posture & gait, depression, cognitive impairment and functional capacity. Follow-up was available from 40 patients (mean follow-up 2.0 years) and 29 controls (mean follow-up 5.9 years). Despite chorea, patients had less daytime motor activity than controls (P < 0.005). This hypokinesia correlated with impaired voluntary movements (r = 0.37; P < 0.01), disturbed posture & gait (r = 0.38; P < 0.005) and especially with reduced functional capacity (r = 0.51; P < 0.0005). During follow-up, hypokinesia remained unchanged in clinically stable patients, but became worse in those whose functional disability progressed (P < 0.005). Hypokinesia seems a core symptom of HD which is related to functional capacity. Actimetric assessment of hypokinesia is responsive to disease progression and can be used as an objective tool for follow-up. © 2001 Movement Disorder Society. [source] THE APPRENDI-BLAKELY CASES: SENTENCING REFORM COUNTER REVOLUTION?CRIMINOLOGY AND PUBLIC POLICY, Issue 3 2007RICHARD S. FRASE Recent Supreme Court decisions have extended jury trial rights and beyond-reasonable-doubt proof standards to certain sentence-enhancement facts. The first two cases, Apprendi v. New Jersey and Ring v. Arizona, were narrow in scope and relatively uncontroversial. But Blakely v. Washington marked a substantial expansion of the rationale and scope of Apprendi, and threatened to invalidate entire sentencing reform systems, both legally-binding guidelines of the type at issue in Blakely and it's sequel, Booker v. United States, and statutory determinate sentence systems like the one invalidated in Cunningham v. California. Each of these decisions has potential effects not only on sentencing severity and disparity in the cases controlled by that decision, but also on prosecutorial, legislative, and sentencing commission measures designed to comply with the decision, avoid it, and/or mitigate its impact. Field resistance and avoidance measures are likely to be stronger in jurisdictions where the existing sentencing system enjoyed broad support; in such jurisdictions, resistance may be particularly strong to the more controversial Blakely ruling. Impact assessments must therefore carefully distinguish the separate impacts of Apprendi and Blakely in each jurisdiction being studied, and the extent of support for the existing sentencing system. Such assessments should also examine pre-existing trends and other independent sources of change; leadership by sentencing commissions or other officials in crafting responsive measures; structural and other features of the sentencing system which render compliance more or less difficult; and second-stage effects, on sentencing, prosecutorial, or sentencing policy decisions, that reflect the prior compliance, avoidance, and mitigation measures adopted in that jurisdiction. The greatest long-term effects may be on prosecutorial, legislative, and commission decisions, rather than on sentencing outcomes. [source] | ||||||||||
