Incline walking: An offloading option for patients with knee OA

Incline walking on a treadmill results in less frontal plane knee loading and more gluteus, hamstrings, quadriceps, and triceps surae muscle activation than level walking, and therefore may benefit patients with knee osteoarthritis or those who have undergone knee replacement.

Out on a limb: Taking on Tommy John

Baseball’s approach to preventing arm injuries so far has been to try to limit loads on the arm itself. But more and more evidence seems to suggest some of the prevention efforts should be focused further down the kinetic chain.

Special Educational Series: Pediatrics

A matter of timing

If an intervention has the potential to treat or prevent lower extremity issues in a child, clinicians and parents are naturally inclined to implement it as early as possible. It makes sense intuitively, and in many cases early intervention is supported by published evidence. But in other cases the picture is less clear.

AFO tuning: Balancing function and satisfaction

Tuning of ankle foot orthoses (AFOs) and AFO-footwear combinations can significantly improve gait in patients with neuromuscular impairments. Even so, some pa- t­ients still prefer their untuned devices, which has led researchers and clinicians to reexamine their approach to intervention.

Return of strength after Achilles tendon surgery

Despite excellent subjective outcomes following Achilles tendon repair, significant plantar flexion and dorsiflexion strength deficits often persist. However, modern trends in postoperative rehabilitation represent a progression toward a more functional strength recovery.

Flexible flatfoot: Foot orthoses and outcomes

Many studies have shown an effect of foot orthoses on biomechanical function in patients with flexible flatfoot, but few studies have focused on patient-centered outcomes. There is a need to investigate the effect of foot orthoses on pain and fatigue in these individuals over time.

Running shoe mass: Can feet tell any difference?

Research suggests that when trying on athletic shoes in a retail store, an individual’s perceptions of shoe mass primarily come from handling the shoes and less (if at all) from test-wearing them. In addition, the foot’s perception of shoe mass does not appear to improve with practice.

Dynamic compression for recovery in athletes

US Olympic Committee researchers have found that peristaltic pulse compression of the lower extremities may provide a means of enhancing the rheological properties of the lower extremities without resorting to extreme temperatures, expensive body work, or stretching.
