Relation of functional independence to balance, exercise capacity, and peripheral muscle strength in individuals with chronic stroke: A cross-sectional study

Abstract

PurposeThis cross-sectional study determined the relationship between functional independence and balance, functional exercise capacity, and knee extensor strength in individuals with chronic stroke. Material and methodsThe study included fifty-four individuals with chronic stroke. A single physiotherapist evaluated clinical features. Assessments included the Functional Independence Measure (FIM), the Tinetti Performance Oriented Mobility Assessment (POMA), the Timed-Up and Go Test (TUG), the 6-min Walk Test (6MWT), and Knee Extensor Strength (KES). ResultsPatients' mean age and body mass index were 60.5 ± 7.13 years and 27.08 ± 4.65 kg/m2. FIM was significantly associated with the POMA (r = 0.644, p = 0.000), TUG (r = -0.723, p = 0.000), and 6MWT (r = 0.569, p = 0.000). FIM was not significantly associated with KES of the paretic side (r = 0.264, p = 0.054), and KES of the non-paretic side (r = 0.207, p = 0.133). However, mFIM was significantly associated with KES of the paretic side (r = 0.432, p = 0.001), and KES of the non-paretic side (r = 0.348, p = 0.010). OutcomesIt was established that there was no relationship between KES and FIM, but that a relationship existed between KES and mFIM. Functional independence is associated with balance ability and functional exercise capacity.
