Out on a limb: Think outside the knee

We hear a lot about various comorbidities associated with knee osteoarthritis (OA), and how addressing those additional conditions can help improve knee pain and function. But a growing body of research suggests one set of comorbidities that knee OA experts may be overlooking are those involving the foot and ankle.

The role of hip extensor strength during cutting

Although most clinicians tend to emphasize hip abductor and external rotator muscle  strengthening in injury prevention and rehabilitation, recent research suggests exercises to increase explosive hip extensor strength may be critical for controlling frontal plane motion during cutting tasks.

Using wearable sensors to characterize CP gait

Inertial measurement units (IMUs) facilitate the creation of a gait analysis system that is portable and suited for use in the clinic. Research suggests IMUs can be used to measure clinically important gait metrics in children with cerebral palsy, which may improve patient outcomes.

Fluoroquinolones and risk of tendon damage

As ciprofloxacin and other fluoroquino­lones are prescribed more frequently, tendon-related adverse effects are also becoming more common. Experts often do not recommend these drugs, particularly for athletes or elderly patients, and emphasize that all patients should know the risks.
