Abstract

Patients with neurological conditions may be affected by spasticity. The Modified Modified Ashworth Scale (MMAS) is a clinical tool used to measure spasticity. The purpose of the present study was to investigate the inter-rater reliability of the MMAS during the assessment of elbow flexor spasticity in adult patients with post-stroke hemiplegia. Twenty-one adult patients with stroke (5 women, 16 men) with a median age of 60 years (interquartile range, 47-68) were tested. Elbow flexors on the affected side were examined. Inter-rater reliability for two inexperienced raters was very good. The weighted Kappa value was 0.81 (Standard Error = 0.097, 95% CI: 0.62-1.00, p = 0.0002). The weighted percentage agreement was 97.4%. The agreement between raters occurred mostly on score 1 (38.1%) followed by score 0 (23.8%). The MMAS yielded reliable measurements between raters when used on patients post-stroke with elbow flexor spasticity.
