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.

Patient Perspective: Walking 600 miles is tough; plantar fasciitis is tougher

In 2008 I walked the 500-mile Camino de Santiago, the medieval pilgrimage route through northern Spain leading to the Cathedral of Santiago de Compostela. It was my first long distance walk, and because I completed it without injury, pain, or a blister, I fancied myself a walking superhero, immune to suffering or discomfort.

Managing foot and ankle injuries in baseball players

Baseball players at all skill levels routinely suffer from foot and ankle injuries, with position players being afflicted more often than pitchers or catchers. Making the correct initial diagnosis without delay can lead to more rapid and effective treatment, rehabilitation, and return to play.

A virtual reality approach to lower extremity rehab

When commercially available active video games are used in rehabilitation settings, often the level of challenge does not match the patient’s ability level. Customized interventions can address these limitations while capitalizing on the fun and motivating aspects of the technology.

Cost-benefit data support reconstruction of ACL tears

In both the short term and the long term, anterior cruciate ligament reconstruction produced greater quality of life improvements at a lower cost compared with rehabilitation only, suggesting that limiting access to ACL reconstruction may be harmful to patients and costly to society.

Effects of targeted exercise on chronic ankle instability

Clinicians and researchers are increasingly utilizing exercise protocols focused on improving proprioception, range of motion, and strength to influence the more active and functional deficits that have been associated with chronic ankle instability in the literature.

Clinicians’ shoes can send mixed message to patients

Patients often look to foot and ankle practitioners for advice about footwear choices. But a recent survey of physicians found that nearly half don’t educate their patients about footwear guidelines, and that only one in…

Patient Perspective: Taking an alternative path to chronic foot pain relief

After a year in a fracture boot with a broken foot, I thought my ordeal was over. I was wrong. The broken bone in my foot, sustained after a fall down a staircase in my home, had occurred midway down the fifth metatarsal bone below my little toe—a site that is notoriously difficult to heal, according to my podiatrist.

Cyclists and foot orthoses: A unique set of challenges

Finding the right orthotic design starts with the space limitations presented by cycling shoes, but the challenges for lower extremity practitioners don’t end there. Factors to consider when prescribing foot orthoses include biomechanics, skill level, cycling discipline, and bike technology.

Foam rolling: Early study findings suggest benefits

Foam rolling is a relatively new therapeutic approach, but early research suggests that it can help improve range of motion and muscle performance and aid in recovery after exercise. Questions remain, however, about the extent to which the effects involve myofascial mechanisms.

Foot and ankle strategies for patients at risk for falls

As a result of limitations in the fall prevention research to date, investigators and
clinicians are often left to make their best guesses about the effect of foot and ankle interventions based on the effect such strategies have on issues related to falls, rather than on falls themselves.

Vitamin D and knee OA: Many theories, few answers

Several patient populations with an increased risk of knee osteoarthritis also are at increased risk for vitamin D deficiency, and research suggests vitamin D levels may be related to knee OA symptoms. The exact nature of the relationship, however, remains perplexing.

Bariatric surgery: Effects on patient gait and function

Existing data suggest bariatric surgery-induced weight loss can lead to rapid improvements in gait and physical function. The surgery may also help to address factors associated with knee osteoarthritis, which itself can affect mobility and function in obese patients.

Influence of stride length on mechanics of pitching

Because power in baseball pitchers is generated from the feet through the core to the throwing arm, the study of stride length and its impact on pitching performance may help define an optimum technique that better protects pitchers from upper extremity injuries.

The ideal running shoe: An elusive, evolving concept

The body of research that has evaluated running shoe prescription and injury suggests the most important factors to consider when selecting a running shoe are that it fits the foot perfectly and that the midsole is comfortable and appropriate for the individual athlete’s running style.
