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.

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.

Bracing affects plantar pressures and inversion, but not most performance tests

Research presented in June at the annual meeting of the National Athletic Trainers Association shed more light on the biomechanical effects of ankle braces that can help reduce the risk of inversion injury.

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.

Bone bruises associated with ligament injuries may predict chondral damage

The distribution of bone bruises associated with acute knee ligament injury is consistent with long-term patterns of chondral damage, according to research from the University of Kentucky in Lexington presented in June at the annual meeting of the National Athletic Trainers Association.

Soccer training intensity affects levels of biomarker for cartilage degradation

Increased exercise duration is associated with elevated levels of a serum biomarker previously found to be an indicator of cartilage damage, according to research from the University of Kentucky in Lexington presented in June at the annual meeting of the National Athletic Trainers Association.

Hip strength deficits characterize both patellofemoral pain and osteoarthritis

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.

Ankle instability patients exhibit landing kinematics suggestive of ACL injury risk

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.

Toning shoe twist: Embattled footwear may still have benefit

The research on toning shoes presented early this month at the annual meeting of the American College of Sports Medicine in San Francisco didn’t add much support for controversial claims that the rocker-bottom footwear promotes muscle activa­tion and energy expenditure. But the presenters did point out more subtle benefits of toning shoes that manufac­turers might find are more acceptable to the Federal Trade Commission.

Balance control in occupational boots reflects shaft height more than mass

In workers wearing occupational footwear, the mass of a boot may be less important for maintaining balance than its shaft height, according to a study presented in late May at the annual ACSM meeting.

Injuries prevent runners from adapting to acute changes in midsole hardness

Injured runners do not make sagittal plane kinematic adaptations to changes in midsole hardness the way that healthy runners do, according to research from the University of Wisconsin-La Crosse (UW-L) presented in late May at the ACSM meeting.

Weight watching: Ten percent gain or loss affects symptoms

Education about weight loss—including why it’s important and how to achieve it—should be “front and center” of any clinical encounter involving patients with knee osteoarthritis (OA), said a researcher who recently published findings on the effects of weight change over time on OA-related pain and functional limitations.
