Clinical and radiological assessment of hemiplegic shoulder pain in stroke patients

Abstract

AbstractBackgroundHemiplegic shoulder pain (HSP) is one of the most common complications of stroke. This work aimed to evaluate and analyze the clinical and radiological features of painful shoulder in hemiplegic stroke patients with evaluating the diagnostic role of shoulder ultrasound and shoulder MR imaging in assessment of the causes of shoulder pain.Methods210 stroke patients with shoulder affection within 3 years of stroke development were enrolled. Clinical assessment including Medical Research Council scoring, The Brunnström motor recovery and Ashworth Scale. Shoulder ultrasound and MR imaging were done for 74 patients with painful hemiplegic shoulder.ResultsThe prevalence of HSP was 35.2% with statistically significantly higher proportion of shorter disease duration, lower muscle power, lower BMR stage with higher proportion of bicipital tendinitis and complex regional pain syndrome in major versus moderate dependence (P < 0.001,P < 0.001,P < 0.001,P = 0.011 andP = 0.001 respectively). On multivariate analysis only short disease duration was statistically significant independent predictor. Participants with disease duration ≤ 2 months have 21.9 times higher odds to exhibit major rather than moderate dependence. By imaging there was high prevalence of joint effusion (47.3%), bicipital tendinitis (44.6%), bursitis (31%) and adhesive capsulitis (29.7%) in painful hemiplegic shoulder with a very good agreement between MRI and US in diagnosis.ConclusionHSP has a high prevalence in stroke patient with increased morbidity due to various factors and US can be used as an alternative or a complementary to MRI for diagnosis of hemiplegic shoulder pain.
