摘要

Introduction: A high number of patients with stroke develop upper extremity spasticity, causing abnormal postures and patterns. These alterations limit the use of arm in functional activities and affect social participation. Aim: To determine the prevalence of spasticity and postural patterns of the upper extremity post stroke. Materials and methods: A cross-sectional descriptive design was used with a prospective follow-up. The sample included 136 patients. The study included 3 measuring times; at 10 days (T1), applying a record with sociodemographic-clinical data, the evaluation of muscle tone in the elbow and wrist and the postural patterns of the UE, and at 3 months (T2) and 12 months (T3) post stroke, re-evaluating tone and patterns. Prevalence was calculated through the one-sample chi-squared (chi 2) test followed by inspection of the standardized residuals (z) in each cell. The Kappa coefficient evaluated the degree of agreement in elbow and wrist tone. Results: The prevalence of spasticity in the elbow was 37.5% at T1, 57.4% at T2, and 57.4% at T3. At each time there was a high degree of agreement between elbow and wrist tone. Patients developed increased elbow tone between T1 and T2, with maintained tone between T2 and T3. Postural pattern III was the most prevalent according to Hefter's classification. Conclusion: The prevalence of spasticity in the elbow and wrist increases between 10 days and 3 months post stroke, and is maintained between 3 and 12 months. The onset of spasticity occurs in almost half of patients during the first 10 days post stroke. Postural pattern III according to Hefter's classification presented the greatest prevalence in the spastic UE.
