Target board test for the quantification of @entity2055 in tremulous XXXX .

@entity1 @entity400 @entity6447 @entity15 @entity2055
OBJECTIVE: The objective was to develop and assess the validity and reliability of a target board test (TBT) for quantifying @entity2055 and measuring @entity6447 in the presence of @entity400 . DESIGN: Each subject was instructed to reach out and mark a target placed at arm's length with a pen (10 times with each hand). Ten @entity1 performed the test twice. SETTING: A hospital-based @entity15 ( @entity15 ) unit. SUBJECTS: Fifty-three @entity1 with @entity15 and upper limb @entity400 / @entity2055 and 20 healthy control subjects. The @entity15 @entity1 were classified into four subgroups: @entity15 control group (n = 13), @entity15 @entity400 group (n = 9), @entity15 @entity6447 group (n = 6), @entity15 mixed ( @entity400 and @entity6447 ) group (n = 25). MAIN OUTCOME MEASURES: The main outcome measures were the average radial distance away from the target (mean R) and the mean directional error (mean V) of the 10 contact points from the target. From these a @entity6447 @entity400 index (DTI) was calculated by dividing mean V by mean R. Also used were a @entity6447 scale, a dysdiadochokinesia scale and a finger-tapping test. RESULTS: Mean R correlated significantly with @entity6447 , dysdiadochokinesia, kinetic @entity400 and (inversely) with the finger-tapping test (all p < 0.005). The median difference between two measurements of mean R for all 10 contact points was 11.3% and 19.0% and for mean V48.3% and 63.4% and DTI 57.2% and 50.5% for the right- and left-hand sides respectively, indicating the considerable directional variability within @entity2055 . CONCLUSION: The TBT provides simple quantitative objective measurements of @entity2055 .
