Sport-related injury and pain classification.

Pain is common in athletes, and pain management in sport has traditionally been equated with injury management. Although both pain and injury interfere with sport performance, they are not synonymous. Acute musculoskeletal injury commonly manifests as nociceptive pain, inflammatory pain, or both.

Differences in gait pattern parameters between medial and anterior knee pain in patients with osteoarthritis of the knee.

Background: Patients with osteoarthritis of the knee have unique spatiotemporal gait alterations. These gait changes have not yet been differentiated according to the location of knee pain. The purpose of this study was to compare the gait patterns of patients with symptomatic knee osteoarthritis that exhibit either anterior or medial joint pain.
