Among people with arthritis, data revealed, the
proportion of respondents who’d used CAM was significantly higher than among those without it (41%
and 34.6%, respectively).5 In this population, herbs, supplements, and vitamins (24%) and mind–body
therapies (21%) were most often used for treatment
purposes, followed by chiropractic (9.4%) and
massage (almost 5%).5 Limitations of these data
include the datedness of the information and the inclusion of multiple types of rheumatic diseases, preventing a determination of CAM use specifically for OA. Other estimates of use range from 59% to 90%
but are often limited by sample location and differences
in the definition of CAM.
