Lower Extremity Review
Knee and ankle sprains in National Football League (NFL) players occurred more frequently on artificial turf than on grass between 2000 and 2009, according to a study commissioned by the NFL Injury and Safety Panel e-published in September by The American Journal of Sports Medicine.
Barefoot-simulating and minimalist shoes are capturing the imagination of runners who hope to avoid injury and increase performance by adopting a forefoot or midfoot strike pattern, but recent research suggests runners don’t necessarily convert their gait simply by switching shoes.
Lower extremity work during a golf swing is positively correlated with both club head velocity and golfer skill level, according to research from the Ohio State University in Columbus, OH.
Kinematic and kinetic differences between dominant and nondominant limbs during cutting in soccer players could help explain previous findings regarding limb dominance and anterior cruciate ligament (ACL) injury risk, according to research from Ball State University in Muncie, IN.
Sophisticated laboratory experiments have documented postural control deficits in athletes with a history of concussion, but research presented in June at the annual meeting of the National Athletic Trainers Association (NATA) suggests clinicians may find it difficult to identify similar deficits in concussed athletes once their other symptoms have resolved.
Hip adduction on landing is a significant predictor of anterior cruciate ligament (ACL) injury risk, according to a large prospective study from the University of North Carolina at Chapel Hill, presented in June at the NATA meeting.
A pain-inducing protocol significantly reduces hip extension strength in patients with patellofemoral pain (PFP), suggesting that hip weakness associated with the condition may be a result and not a cause, according to research from the University of Wisconsin-Milwaukee presented in June at the NATA meeting.
The exploding popularity of so-called extreme conditioning programs is now infiltrating the armed forces, prompting military sports medicine experts to take a closer look at the potential risks and benefits of high intensity exercise.
Patellofemoral osteoarthritis (PFOA) is associated with deficits in hip abduction strength, a similarity to patellofemoral pain syndrome (PFPS) that appears to support the theory that the two conditions lie on the same continuum, according to research from the University of Calgary presented in late May at the ACSM meeting.
Sagittal plane landing kinematics in patients with chronic ankle instability (CAI) mimic those associated with risk of anterior cruciate ligament (ACL) injury, suggesting that similar neuromuscular control deficits may be involved in both processes, according to research from the University of Toledo (OH) presented in late May at the ACSM meeting.
Backward running involves lower patellofemoral joint compression forces than forward running and is a viable strategy for rehabilitation of patellofemoral pain syndrome in runners, allowing them to continue exercise without increasing these forces, according to UK research e-published in April in the Journal of Biomechanics.
A retrospective analysis e-published in April in Clinical Orthopaedics and Related Research found physical examination is superior to magnetic resonance imaging (MRI) for diagnosis of acute Achilles tendon ruptures. Investigators at Thomas Jefferson University Hospital in Philadelphia compared 66 patients…
Interactions between gender and footwear type affect landing mechanics in soccer players, according to research e-published in April in the Scandinavian Journal of Medicine & Science in Sports. Investigators at Duke University in Durham, NC, conducted motion analysis on 28…
Exercises prescribed for rehabilitation after anterior cruciate ligament (ACL) reconstruction should be designed to protect the healing graft from excessive strain in addition to rebuilding muscle strength and activation, according to evidence-based recommendations from a multicenter team of experts.

The metabolic cost of running increases with heavier footwear, but barefoot running is no more metabolically efficient than running in a lightweight shoe, according to research from the University of Colorado at Boulder. In 12 men experienced in barefoot running,...
