Brains and sprains: Is there an extremity-concussion link?

The sports medicine community is demonstrating increasing interest in the possibility that neurocognitive impairment and musculoskeletal injury may be related, as evidenced most recently by an exchange in the letter to the editor section of the September issue of The American Journal of Sports Medicine (AJSM).

Achilles tendon in runners maintains stiffness despite stress of marathon

Running a marathon does not significantly affect Achilles tendon stiffness, suggesting that overuse may not explain Achil­les ruptures in runners, according to a Finnish study published in the October issue of the Journal of Experimental Biology.

NFL study finds higher rates of sprains on artificial turf than on grass surfaces

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.

ACL reconstruction fails to improve return-to-sport rates after one year

Athletes who undergo surgical reconstruction after anterior cruciate ligament (ACL) injury are no more likely to return to sports one year later than those treated nonoperatively, according to a Norwegian study.

Midfoot index of load differentiates postarthrodesis gait from normal

Swiss researchers have found that pedobarographic differentiation between ankle arthrodesis patients and healthy volunteers can be narrowed down to a single variable, midfoot index of load—a finding that could make the technology much more accessible to the average clinician.

Ambling modifiers: Finding a patient-friendly gait for knee OA

In the interest of improving compliance, studies of gait modifications to reduce moments and forces at the knee in patients with knee osteoarthritis (OA) are increasingly focusing on gait alterations that will not make patients self-conscious.

Kinetic biofeedback training reduces knee abduction moment on landing

Real-time biofeedback training can help female athletes reduce knee abduction moments (KAM) during landing, which may in turn reduce risk of anterior cruciate ligament injury, according to preliminary research from Cincinnati Children’s Hospital.

Multimodal adaptive rehab improves propulsive impulse in stroke patients

Gait training on a dual-belt treadmill in an adaptive virtual environment can help improve propulsive impulse in the paretic limbs of individuals with hemiparesis following stroke, according to research from the University of North Carolina at Chapel Hill.

Lost in transition: Minimalist shoes don’t always alter gait

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.

Soccer study explores factors that may link limb dominance to ACL injury risk

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.

Clubfoot conversion: Nearly all surgeons adopt Ponseti method

The shift away from aggressive surgery to correct clubfoot in now all but complete, according to research published in July in the Journal of Pediatric Orthopaedics (JPO). The study shows the Ponseti me­thod is now the treatment of choice for the vast majority of practitioners and that increased understanding of the technique has resulted in better outcomes.

Selective plantar fascia release assists healing of recalcitrant forefoot ulcers

Korean surgeons have developed an alternative to Achilles tendon lengthening for reducing plantar pressure and promoting wound healing in patients with diabetic foot ulcers.

Study finds noise-enhanced insoles reduce gait variability in older adults

A subsensory level of mechanical noise delivered directly to the foot soles of healthy older adults during walking has the potential to normalize gait variability and possibly reduce the risk of falls, according to research published in July in Gait & Posture.

Fusion vs replacement: Both improve gait, but well short of normal

Functional outcomes for total ankle re­place­ment (TAR) in patients with end-stage ankle arthritis appear to match or exceed those of ankle fusion, according to research presented in June at the an­nual meeting of the American Ortho­paedic Foot & Ankle Society (AOFAS).

ATFL repair with any of three methods decreases ligament stiffness, strength

Three different methods for repairing the anterior talofibular ligament (ATFL) leave the repaired structure significantly stiffer and weaker than an intact ligament, which may have implications for ankle injury rehabilitation, according to research presented in June at the AOFAS meeting.

Effects on plantar flexor endurance, power linger after gastroc recession

Tasks requiring plantar flexor endurance and push-off power remain difficult for patients long after an otherwise successful gas­tro­cnemius recession for treatment of Achilles tendinopathy, according to findings presented in June at the AOFAS meeting.

Concussion conundrum: Chronic postural deficits elude detection

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 stands out as predictor of future ACL injury risk

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.

In patients with patellofemoral pain, hip weakness may be result, not cause

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.

Arthroscopy attrition: 2002 study changes practice patterns

The number of knee arthroscopy proce­dures performed in patients with osteo­arthritis (OA) has greatly decreased since the 2002 publication of a high profile New England Journal of Medicine study that questioned the procedure’s effectiveness, according to research from the Cleveland Clinic in Cleveland, OH.
