Prepare for landing: Bladed cleats may put fifth met at risk

Bladed soccer cleats were associated with increased forefoot loading during a jump-landing task, which may lead to a higher risk of fifth metatarsal stress fractures, according to a study published in the September-October issue of the Journal of Athletic Training.

Leg mechanics, training conditions may predict Achilles pain in runners

Investigators at the University of Tuebingen in Germany have identified alterations in lower leg mechanics and higher impacts caused by “fast” training conditions (e.g., interval training sessions, competitions) as potential risk factors for Achilles tendon pain in runners.

Location, location: High pressures don’t predict all ulcers

Practitioners often deem all areas of elevated peak plantar pressure in patients with diabetes at some risk for ulceration. A study published in September, how­ever, suggests this risk varies with the specific location of pressure, and investigators say findings highlight the importance of monitoring plantar pressure as part of preventive care.

Neuropathy results in less sensory loss at fifth metatarsal than hallux

Clinicians should carry out quantitative vibration testing for sensory loss in patients at risk for diabetic neuropathy at the hallux, according to research that confirms the hallux undergoes greater sensory loss than the fifth metatarsal, an alternate location for vibration testing.

Imaging reveals intrinsic muscle deterioration in neuropathic feet

Diabetic neuropathy is associated with increased levels of intrinsic foot muscle deterioration, which may contribute to foot deformity and ulceration, according to research presented in September at the annual meeting of the American Society of Biomechanics in Omaha, NE.

Investigating OA: Studies revisit underlying variables

Knee osteoarthritis researchers are taking a closer look at the factors that influence knee adduction moment (KAM) and also considering the contributions of sagittal plane variables, as illustrated by studies presented in September at the American Society of Biomechanics (ASB) annual meeting in Omaha, NE.

Altered landings suggest link between neurocognitive scores, ACL injury risk

Female athletes with low neurocognitive scores are more likely than those with higher scores to demonstrate altered landing mechanics consistent with elevated anterior cruciate ligament (ACL) injury risk, according to findings that could have implications for concussion management.

Limited arch excursion characterizes individuals with patellofemoral pain

Patients with patellofemoral pain (PFP) have less medial longitudinal arch excursion during stair descent than healthy individuals, according to a Brazilian study that may help explain the effects of foot orthoses in patients with PFP.

Amputation, reulceration rates fall after two years of orthotic therapy

Orthotic therapy in patients with diabetes and a history of foot ulcers was associated with dramatic decreases in reulceration and amputation rates, according to data from Spanish researchers at the Universidad Complutense de Madrid.

Removable plug insoles significantly reduce pressure, as do arch supports

Researchers from Taiwan confirmed that insoles with removable plugs reduce forefoot plantar pressures in patients with diabetic neuropathy, and those pressures are further reduced by adding arch support.

Stress management: Landing mechanics predict fracture risk

Landing biomechanics have long been a focus of anterior cruciate ligament (ACL) injury research, but they may also be predictive of lower extremity stress fracture, according to a study presented in July at the American Orthopaedic Society for Sports Medicine (AOSSM) meeting in Chicago.

Customizing stochastic resonance boosts balance effects in FAI patients

Stochastic resonance stimulation (SRS) more effectively improves balance in patients with functional ankle instability (FAI) when optimized based on each patient’s sensory threshold than when all patients receive the same treatment, according to research from Virginia Commonwealth University in Richmond.

Brace relations: Complex effects are not only mechanical

Research presented in late June at the annual National Athletic Trainers Association (NATA) meeting in Las Vegas added to the body of evidence suggesting that the effects of ankle bracing are not solely mechanical, and that even the mechanical effects may be more complicated than they seem.

Positives for PFP: Benefits of six-week rehab are retained

Six weeks of lower extremity strengthening in runners with patellofemoral pain (PFP) leads to improvements in pain and function that are retained six months later, regardless of whether the rehabilitation focuses on the knee or the hip, according to research presented in late June at the National Athletic Trainers Association (NATA) annual meeting in Las Vegas.
