Objective:
To investigate two approaches to treating patients with persistent dressing problems
and cognitive difficulties following stroke.
Design:
Pilot randomized controlled trial.
Setting:
Inpatient stroke rehabilitation service.
Subjects:
Seventy consecutive stroke patients with persistent dressing problems and accompanying
cognitive difficulties at two weeks after their stroke.
Interventions:
Patients were randomly allocated to six weeks of either a systematic neuropsychological
approach, based on analysis of dressing problems and further cognitive testing, or to
the control group who received conventional (functional) dressing practice. Both groups
received treatment three times a week in accordance with two separately prepared
manuals.
Main measures:
Nottingham Stroke Dressing Assessment (NSDA), Line Cancellation, 10-hole peg transfer
test, Object Decision, Gesture Imitation. Patients were assessed at six weeks after
randomization by an independent assessor masked to group allocation.
Results:
Both neuropsychological and functional groups improved performance on the NSDA over the
treatment period (31% and 22%, respectively) but there was no significant difference
between groups at six weeks. However, the neuropsychological group showed a
significantly greater improvement on a line cancellation test of visual neglect
(t(62) = 2.1, P < 0.05) and a planned subanalysis
for those with right hemisphere damage showed a trend towards better dressing outcome
(P = 0.07, one-tailed).
Conclusions:
Results demonstrate the potential benefits of a systematic neuropsychological approach
to dressing therapy, particularly for patients with right hemisphere damage. This study
suggests the need for a phase III study evaluating the efficacy of a systematic
neuropsychological approach in treating dressing difficulties, targeting patients with
right hemisphere stroke and visuospatial impairments.
