Abstract
- Background: Patients often experience pain as a result of a stroke. However, the mechanism of this pain remains uncertain. Our aim was to investigate the relationship between pressure pain thresholds (PPTs) and disability pain in patients with hemiplegic shoulder pain (HSP). Methods : Twenty-six post-stroke patients (age 53.35 ± 13.09 years) and healthy controls (54.35 ± 12.37 years) participated. We investigated spontaneous shoulder pain, disability pain perception through the shoulder pain and disability index (SPADI), and the PPTs over joint C5-C6, upper trapezius, deltoid, epicondyle, second metacarpal, and tibialis anterior, bilaterally.<br />Results: The analysis of variance (ANOVA) showed significant differences in pain between groups ( p < 0.001) and differences in the SPADI ( p < 0.001) between groups but not between sides for PPTs over deltoid (group: p = 0.007; side: p = 0.750), epicondyle (group: p = 0.001; side: p = 0.848), and tibialis anterior (group: p < 0.001; side: p = 0.932). Pain in the affected arm was negatively associated with PPTs over the affected epicondyle ( p = 0.003) and affected tibialis anterior ( p = 0.009). Pain (SPADI) appeared negatively correlated with PPTs over the affected epicondyle ( p = 0.047), and disability (SPADI) was negatively associated with PPTs over the affected tibialis anterior ( p = 0.041).<br />Conclusions: Post-stroke patients showed a relationship between widespread pressure pain hypersensitivity with lower PPT levels and pain disability perception, suggesting a central sensitization mediated by bilateral and symmetric pain patterns.<br />Competing Interests: The authors declare no conflict of interest.
