Clinical pain intensity and experimental pain sensitivity vary among Asian Americans and Whites with knee osteoarthritis

The clinical and experimental pain responses vary significantly among different ethnic communities. The pain in older Asian Americans remains poorly understood compared with non-Hispanic white (NHW) participants who are well reported.  Ahn et al. conducted a study to specify the differences in clinical pain intensity and experimental pain sensitivity among older Asian American and NHW participants with knee osteoarthritis (OA).

The data was collected from 50 Asian Americans aged 45 to 85 (28 Korean, 9 Chinese, 7 Japanese, 5 Filipino, and 1 Indian). This was compared with 50 age-matched and sex-matched NHW individuals with symptomatic knee OA pain. To estimate the intensity of clinical knee pain, the Western Ontario and McMaster Universities Osteoarthritis Index and Graded Chronic Pain Scale was used. Also, quantitative sensory testing was used to calculate the experimental sensitivity to heat-induced and mechanically induced pain.

It was reported that Asian American participants had notably higher levels of clinical pain intensity than NHW participants with knee OA. Also, Asian American participants had significantly higher experimental pain sensitivity than NHW participants with knee OA.

These results support the growing literature regarding the ethnic and racial differences in clinical pain intensity and experimental pain sensitivity. Particularly, Asian Americans may be at risk for clinical pain and augmented experimental pain sensitivity. Further investigation is required to reveal the mechanisms underlying ethnic group differences in pain between Asian Americans and NHWs, and also to confirm that ethnic group disparities in pain are ameliorated.
