PURPOSES: To investigate the relationship between associated reactions and a) spasticity, b) contracture and c) coordination.
METHODS: Associated reactions were measured as magnitude of muscle activity in the affected limb during a 50% maximum voluntary contraction of muscles in the unaffected limb. Spasticity was measured as hyper-reflexia during passive muscle stretch, coordination as performance during a tracking task, and contracture as loss of range of motion. Chi-square analysis was used to examine the association between associated reactions and spasticity, and linear regression to examine the relationship between associated reactions and spasticity, coordination and contracture.
RESULTS: Twenty-three people with hemiplegic cerebral palsy aged from 15 to 47 years (mean [SD]: 29 years [9]) participated. Thirteen participants exhibited spasticity, and six participants exhibited associated reactions. Five of the six participants with associated reactions also had spasticity (χ2=2.37, p=0.12). Associated reactions were highly correlated with spasticity (r=0.77, p=0.001), but not with contracture (r=0.35, p=0.29) or coordination (r=-0.31, p=0.30).
CONCLUSIONS: Although 27% of participants exhibited associated reactions, and these were mostly small, associated reactions appear to be an expression of spasticity in hemiplegic cerebral palsy.
