OBJECTIVE : To analyze responsiveness to change of 2 outcome measures in the
lateropulsion population after stroke. Lateropulsion describes an atypical
balance problem after stroke where patients actively push themselves toward their
paretic side. Secondary aims were to measure the incidence of lateropulsion and
evaluate the site of the brain most commonly involved in lateropulsion. DESIGN:
Stroke patients were screened for lateropulsion on admission to rehabilitation.
Those demonstrating lateropulsion were assessed every 2 weeks using 2 scales to
measure progress. Analysis of variance and the standardized response mean (SRM)
were used to analyze change for each scale. SETTING: Rehabilitation and geriatric
units. PARTICIPANTS: Prospective purposive sample of stroke patients (N=43)
demonstrating lateropulsion on admission from a consecutive admission sample of
160. To allow comparison, data from 43 stroke patients who did not display
lateropulsion were collected retrospectively, matched on age (+/-5y) and sex.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Incidence of lateropulsion
was calculated as a percentage of stroke patients admitted. Responsiveness to
change was measured by using the Burke Lateropulsion Scale (BLS), to quantify
severity of lateropulsion, and the Postural Assessment Scale for Stroke (PASS),
which measures postural abilities. RESULTS: Of 160 stroke patients, 26.9%
displayed lateropulsion (mean age, 72y; 51% men). The BLS and PASS had high
levels of measurement responsiveness (BLS SRM =1.48 and 2.24; PASS SRM =1.76 and
1.87) at 4 and 8 weeks, respectively. CONCLUSIONS: The BLS and PASS are
responsive scales to monitor progress and recovery during rehabilitation. As more
than 25% of stroke patients admitted to rehabilitation may exhibit lateropulsion,
these 2 scales could be valuable in monitoring progress and designing future
intervention studies.
