Walking energetics and fatigue are associated with physical activity in people with knee osteoarthritis.

Clin Biomech (Bristol, Avon) 2021 Jul 17;88:105427. Epub 2021 Jul 17.

Department of Kinesiology and Nutrition, University of Illinois at Chicago, 1919 W. Taylor St., 650 AHSB, Chicago, IL 60612, USA.
