Gait and Balance Outcome Measures Are Responsive in Severely Impaired Individuals Undergoing Inpatient Stroke Rehabilitation

Abstract

ObjectiveTo investigate whether gait and balance outcome measures in patients with severe gait and balance impairments at admission to inpatient rehabilitation provided additional and meaningful information beyond customary measures. Specifically, this study investigated whether individuals who obtained low scores at admission exhibited improvements that exceeded the established minimal detectable change during inpatient rehabilitation. We also investigated whether gait outcomes would capture changes in function not identified by customary measures. DesignSecondary analysis of a knowledge translation project aimed at increasing the systematic collection of these outcome measures in a poststroke cohort. SettingSubacute inpatient rehabilitation facility. ParticipantsIndividuals<2 months poststroke (N=157) with 34-43 with severe deficits including Berg Balance Scale≤5, 10-meter walk test=0 m/s, or 6-minute walk test=0 m. InterventionNot applicable. Main outcome measuresBerg Balance Scale, 10-meter walk test, 6-minute walk test. ResultsAfter 1 week of rehabilitation, 41%-53% of severely impaired individuals had changes above minimal detectable changes in gait and balance outcomes, which increased to 68%-84% at discharge. Across the entire cohort, FIM locomotion scores failed to identify changes in gait function for 35% of participants after 1 week of rehabilitation. ConclusionsRoutine assessment of gait and balance outcome measures in patients with severe deficits early poststroke may be beneficial. These measures were responsive after 1 week of rehabilitation and detected changes not captured by customary measures. Routine use of a standardized gait and balance assessments may provide clinicians with important information to guide clinical decision making.
