Towards a mechanism-based view on post-stroke shoulder pain: Theoretical considerations and clinical implications

Abstract

The assessment and treatment of post-stroke shoulder pain (PSSP) is largely based on the assumption that pain is due to biomechanical alterations within the shoulder joint after stroke. However, current treatment often provides limited pain relief, leading to a considerable number of patients with persistent pain. This suggests that PSSP may not be merely due to simple nociception from the shoulder joint. A better understanding of the neurophysiological mechanisms underlying the development and perpetuation of PSSP is needed. Here, a theoretical framework for presumed PSSP mechanisms and their assessment is presented based on key concepts applied in pain research. This theoretical framework ..
