The role and efficacy of exercise on a joint inflicted with arthritis has been the focus of many studies and clinical research trials across the globe. This article will examine recent literature on the impact that exercise has on arthritis, particularly osteoarthritis.
According to a clinical study published in Arch Phys Med Rehabi 2009 Jun;90(6):897-904, investigators recruited patients inflicted with knee arthritis to investigate whether weight-bearing (WB) exercise enhances functional capacity to a greater extent than nonweight-bearing (NWB) exercise. Participants were randomly assigned to WB exercise, NWB exercise, or a control group (no exercise).
WB exercise and NWB exercise groups underwent an 8-week knee extension-flexion exercise program. Walking speed, muscle torque, and knee reposition error were assessed before and after intervention. Investigators discovered that equally
