Differences in recovery from constructional apraxia after right and left hemisphere stroke?

Previous comparisons of constructional apraxia after right and left hemisphere damage have not investigated the influence of time since onset. This paper reports some preliminary findings from stroke patients in a physical rehabilitation trial. Fifty-five patients with right hemisphere damage and 65 with left hemisphere damage were assessed on the WAIS-R Block Design test at 1 month and 6 months post stroke. The groups were similar at 1 month but the left hemisphere group showed better average recovery by 6 months. There was great variability in amount of recovery within the left hemisphere group, suggesting individual differences in initial reasons for failing Block Design, and corresponding differences in the recovery process. Compensation by the right hemisphere is discussed as one possible process. Future detailed longitudinal studies may be useful in contrasting the cognitive deficits which underlie constructional apraxia after right-sided and left-sided lesions, and would provide evidence on mechanisms of recovery and adaptation.

Enhanced physical therapy for arm function after stroke: a one year follow up study.

Ninety seven patients with stroke who had participated in a randomised trial of conventional physical therapy nu an enhanced therapy for arm function were followed up at one year. Despite the emphasis of the enhanced therapy approach on continued use of the arm in everyday life, the advantage seen for some patients with enhanced therapy at six months after stroke had diminished to a non-significant trend by one year. This was due to some late improvement in the conventional therapy group whereas the enhanced therapy group remained static or fell back slightly. It is recommended that trials should be conducted comparing very intensive therapy for the arm with controls without treatment. This would provide a model of the effects of therapy on intrinsic neural recovery that would be relevant to all areas of neurological rehabilitation.

Arm function after stroke. An evaluation of grip strength as a measure of recovery and a prognostic indicator.

The value of strength of voluntary grip as an indicator of recovery of arm function was assessed by testing 38 recent stroke patients using a sensitive electronic dynamometer, and comparing the results with those from five other arm movement and function tests (Motricity Index, Motor Club Assessment, Nine Hole Peg Test, and Frenchay Arm Test). This procedure allowed measurement of grip in a large proportion of patients, and strength correlated highly with performance on the other tests. Measuring grip over a six month follow up period was a sensitive method of charting intrinsic neurological recovery. The presence of voluntary grip at one month indicates that there will be some functional recovery at six months.
