| Popis: | Impaired balance and weak muscle strength are common deficits associated with stroke. Limited research has examined the relationship between balance and strength in people post-stroke.To investigate the association between balance and muscular strength in people post-stroke.A total of 11 people with chronic stroke, who were community dwelling and ambulatory, completed balance and strength assessments. A computerized dynamic posturography system was used for Limits of Stability (LOS) test, Sit-to-Stand (STS) test, and the Modified Clinical Test of Sensory Interaction on Balance (mCTSIB). Additionally, a computerized dynamometer was used to assess the isometric muscle strength of flexion/extension in the core (the trunk) and the leg (the hip, knee, and ankle). Pearson correlation analysis was used to investigate the relationship between balance and muscle strength measurements.Endpoint excursion (EPE) (r = .646; p 0.032) and maximum excursion (MXE) (r = .613; p 0.045) of LOS test were positively correlated with core and leg strength (CL). Specifically, both EPE (r = -.792; p 0.004) and MXE (r = -.623; p 0.041) in backward direction had strong correlations with CL. Core strength also showed a positive correlation with EPE of LOS test (r = .636; p 0.035) while the composite leg strength did not. Lastly, STS and mCTSIB tests did not demonstrate significant associations with muscle strength.The results indicate that the CL have a strong relationship with the ability to shift body weight in multiple directions, particularly backward, among people post-stroke. However, static balance and STS performance do not appear to be related to muscle strength. |
