Prevalence and Time Course of Post-Stroke Pain: A Multicenter Prospective Hospital-Based Study
Here, in this study the pain after stroke is measured in the different phases leading to some interesting results. These stages are the: chronic, sub-acute and acute stages to reveal the intensity of pain.
Pain prevalence data for patients at various stages after stroke.
Four hundred forty-three prospectively enrolled stroke survivors.
All patients underwent bedside clinical examination. The different types of post-stroke pain (central post-stroke pain, musculoskeletal pains, shoulder pain, spasticity-related pain, and headache) were diagnosed with widely accepted criteria during the acute, sub acute, and chronic stroke stages. Differences among the three stages were analyzed with χ (2)-tests.
The mean overall prevalence of pain was 29.56% (14.06% in the acute, 42.73% in the sub acute, and 31.90% in the chronic post-stroke stage).
Time course differed significantly according to the various pain types (P < 0.001). The prevalence of musculoskeletal and shoulder pain was higher in the sub acute and chronic than in the acute stages after stroke; the prevalence of spasticity-related pain peaked in the chronic stage. Conversely, headache manifested in the acute post-stroke stage. The prevalence of central post-stroke pain was higher in the sub acute and chronic than in the acute post-stroke stage. Fewer than 25% of the patients with central post-stroke pain received drug treatment.
Pain after stroke is more frequent in the sub acute and chronic phase than in the acute phase, but it is still largely undertreated.
