participants' characteristics (age, weight, height and BMI-p>0.05). OAG presented statistically significant worse values in sarcopenia parameters than CG group, presenting lower ASM (p¼0.041), worse performance on 40-meter Fast-paced Walk Test (p¼0.020) and lower right (p<0.01) and left (p<0.01) handgrip strength. In addition, as expected, OAG participants had statistically significant higher scores for pain, stiffness, physical function, and total scores for the WOMAC questionnaire (p <0.001 for all domains) and lower functional performance in the 30s Chair Stand Test. (p ¼ 0.001) and Stair climb test (p <0.001). Conclusions: In addition to worse symptoms and functional performance, middle-aged adults with knee OA have worse sarcopenia parameters than non-knee OA individuals. This may indicate that sarcopenia may be present early in these patients, so treatment and prevention strategies should also focus on these parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
