Women’s Work: Overcoming gender barriers in lower extremity specialties

In lower extremity healthcare, as in politics, it hasn’t been easy for women to succeed in traditionally male-dominated roles. The gender demographics have shifted toward parity over time—in some specialties more than others—but challenges still remain.

Management of athletes with excessive pronation

Pronation is a triplanar movement and is the combination of rearfoot eversion, midfoot abduction, and talocrural dorsiflexion.1 Pronation in normal gait allows flexible, adaptive changes to varying types of terrain; it dissipates ground reaction forces; and encourages lower extremity internal rotation.

Role of bariatric surgery in patients with knee OA

Weight loss following bariatric surgery can have biomechanical and symptomatic benefits for obese patients with knee osteo­arthritis (OA). But it’s less certain whether that weight loss can also reduce the risk of obesity-related complications following total knee arthroplasty.

Insole research explores postural control effects

A growing body of evidence suggests that foot orthoses may be a helpful addition to other therapies for improving balance and potentially reducing the risk of falls. The findings have been mixed, however, and clinical enthusiasm for this type of insole intervention also varies.

Management of Achilles tendinopathy in runners

Achilles tendinopathy is a common lower extremity injury in athletes as well as nonathletes. The Achilles tendon is often a site of injury in runners and is the second most common running-related musculo­skeletal injury, after medial tibial stress syndrome, with an…

Uneven terrain: Tactics for orthotic-device users

Helping patients manage an orthotic device can be challenging, but doing so in the face of uneven terrain is a balancing act between stability, mobility, and strength. Device adjustments and rehabilitation pro­tocols can help patients avoid asymmetries and reduce the risk of falling.

Foot rotation during gait in patients with knee OA

Rotating the foot in or out during gait is associated with significant decreases in frontal plane knee load during early or late stance, respectively, and can be effective for reducing pain and potentially slowing the progression of…

Limb length discrepancy: When, how to intervene?

Limb length discrepancies (LLDs) as small as 1.5 cm can significantly affect gait, and some clinicians choose to intervene in cases of even smaller discrepancies. Many LLDs can be addressed orthotically, but surgical techniques are becoming less invasive and more effective.

Region-specific foot pain doesn’t always match pressures, forces

Gait compensation may play role – The location of foot pain doesn’t always correspond with elevated plantar pressures and abnormal forces, which suggests the availability of region-specific compensatory gait mechanisms may play a role, according to recent research using Framingham Foot Study data.
