physical activity, osteoarthritis, knee replacement, biomechanics


Evidence-based research on pain management techniques, exercise, and aquatic therapy programs provides guidance for recreation therapists working with patients with orthopedic impairments such as osteoarthritis (OA) and total knee replacements (TKRs). However, substantiated recommendations for specific physical activities to be used with this population are not available. This leaves recreation therapy (RT) practitioners with inadequate direction on the appropriate activities to prescribe to their patients. This research note is an abbreviation of a larger study (J.L.P. et al., unpublished data, 2014) and examines the knee joint kinematics and kinetics in healthy older adults during golf and bowling with comparisons made between those experienced during walking and stair ascent and descent. Understanding the knee biomechanics in a healthy population is an important first step in gathering scientific evidence needed to advance our field. Future research examining knee biomechanics related to various recreation activities will be instrumental in allowing RT specialists to develop practice guidelines for men and women with OA and TKR in the future.
