Hip strength asymmetry and patellofemoral pain

Hip strength asymmetry has been observed in patients with existing patello­femoral pain syndrome (PFPS) and poten­tially could be used to screen for at-risk individuals.

Shoring up the rotation: The importance of hip mechanics in pitching

Over the course of a season, collegiate pitchers undergo changes in hip rotational range of motion and hip strength—changes that could increase injury risk or negatively affect performance.

Managing hallux limitus and rigidus in athletes

The terms “hallux limitus” and “hallux rigidus” refer to a degenerative process of the great toe joint that was first described by Davies-Colley1 in 1887 and termed hallux flexus. Cotterill later coined the term hallux rigidus.2 The two terms represent a progression in…

Achilles experts ponder effects of heel elevation

After an Australian study raised questions about the conventional practice of elevating the heel to decrease Achilles tendon load, researchers and clinicians have been revisiting what is known about the many factors—including pain—that can affect tendon load and function.

Influence of estrogen on the plantar fascia

Reported effects of estrogen on knee ligaments and the Achilles tendon raise questions about how the plantar fascia might be altered during the menstrual cycle and how those changes might affect injury risk.

The clinical implications of accelerated knee OA

Accelerated knee osteoarthritis (OA), defined by very rapid radiographic disease progression, is also associated with earlier and more severe symptoms than traditional OA. Identification of…

Plantar fasciitis: clinical concerns in cleated sports

Cleated sports are associated with a high incidence of lower extremity injuries. American football and soccer are particularly troublesome due to unique risk factors involving footwear design, loading patterns, and sport-specific biomechanics.

Texting while walking: Gait adaptations and injury implications

It’s not surprising that tactile interaction with a smartphone while walking can increase the risk of traumatic injury, but texting while walking also affects gait in ways that may ultimately have long-term effects.

Active Stance: Patients with at-risk feet need collaborative care

In a recent editorial in The Lancet Diabetes-Endocrinology,1 Lipsky and colleagues wrote that diabetic foot disease “…is not a one doctor disease—it demands multidisciplinary care. Furthermore, as a notoriously unglamorous problem, the disease depends on…

Biomechanists explore effect of obesity on falls

Obese patients have an increased risk for falls and fall-related injury, not just because of the loads involved, but also because of the strategies they use to recover from a trip or slip. Findings from a growing body of research will help in developing interventions to minimize that risk.

Dynamic load analysis for injury prevention

Identifying loading patterns associated with Jones fractures and other common sports-related injuries can assist with the development of custom modifications to footwear, insoles, and training programs to help reduce injury rates and enhance athletic careers.

Plantar fasciitis: Clinical considerations in runners

Clinicians should advocate for the cost-effective, judicious use of foot orthoses for runners with plantar fasciitis, in accordance with the present body of knowledge.

Outcomes after ACL surgery: The importance of graft type

In an attempt to decrease the risk of re-rupture and revision surgery after anterior cruciate ligament reconstruction, practitioners are refining the decision process regarding which procedure is best for which patient.

Plantar fasciitis: Clinical concerns in basketball

Basketball is associated with a high number of lower extremity injuries, often related to footwear and the unique biomechanics and repetitious motion of the sport. This reflects the evolution of basketball from a refined sport to one of extreme physical contact and leverage. At elite levels of competition, the joint loading that comes with…

Running modifications and reducing injury risk

Evidence suggests that no one foot strike style can be expected to decrease injury risk in all runners, and that switching foot strike patterns can have unintended consequences. Using a shorter stride length, however, can be an effective alternative for some runners.

Strength training: Bone health benefits for men

Men with low bone mass are much less likely than their female counterparts to receive treatment. But research suggests that resistance exercise is a safe and effect­­ive way to improve bone mineral density in men and, in turn, reduce the risk of fracture and related complications

Ankle instability rehab emphasizes individuality

Research presented at the most recent International Ankle Symposium indicates that rehabilitation for chronic ankle instability is evolving from a one-size-fits-all approach to an increased focus on matching specific interventions to the patients who are most likely to benefit.

Flexible flat foot: Effects of orthoses during gait

In this original investigation, researchers analyzed the biomechanical effects of a foot orthosis in patients with flexible flat foot during walking and the extent to which those functional effects are consistent with proposed theories about the device’s mechanism of action.

Biomechanics of propulsion: Implications for AFOs

For many patients, the ability of an ankle foot orthosis to enhance propulsion is key to improving gait efficiency and reducing fatigue. But experts are only beginning to understand the biomechanical complexities that influence propulsion, which start with push-off but don’t end there.

Footwear, traction, and the risk of athletic injury

High degrees of rotational traction associated with athletic footwear can increase the risk of noncontact lower extremity injury following an unexpected neuromuscular perturbation, possibly by increasing biomechanical joint loading at the ankle and knee.

Compression and clots in athletes who travel

Hemostatic activation following a marathon is lower in athletes who run with compression socks than those who run with typical athletic socks, suggesting the garments may help reduce the risk of postexercise clot formation in athletes who travel to events.
