ACL bracing study suggests subgroup of athletes most likely to be responsive

Preliminary findings presented in early June at the 2016 American College of Sports Medicine (ACSM) meeting in Boston suggest there may be a subgroup of athletes who are most likely to respond positively to knee bracing after anterior cruciate ligament (ACL) reconstruction.

Runners’ baseline may determine effect of barefoot switch on loading symmetry

Among habitually shod runners with a recent history of injury, those with the greatest magnitudes of loading asymmetry are those who are most likely to become more symmetrical after switching to barefoot running, according to…

CAI and the CNS: Excitability may influence instability

For individuals with chronic ankle instability (CAI), the somatosensory feedback necessary for postural adjustments, walking, and running may be hampered by a decrease in soleus spinal reflex excitability, according to a new study in the Journal of Athletic Training.

fMRI study supports use of multiple exercises to prevent hamstring injury

A multicenter functional magnetic resonance imaging (fMRI) study indicates that no single exercise activates all of the hamstring and synergist muscles in professional soccer players, suggesting a combination of exercises may be optimal for hamstring injury prevention.

Metabolic activity suggests Achilles tendons are still healing at 6 months

Metabolic activity evident six months after an Achilles tendon rupture—when rehabilitation protocols typically allow running and other high-load activities—suggests the tendon is still healing at that time, according to research from Denmark.

Get stronger, live longer: But few older adults meet US guidelines

Strength training twice weekly, as recommended by two national organizations, can help reduce all-cause mortality in older US adults, but fewer than 10% meet that recommendation, according to a study from Pennsylvania State University.

Soccer study finds steady rate of ACL injuries, disappointing 3-year outcomes

Despite advances in prevention and intervention, anterior cruciate ligament (ACL) injuries are no less common among professional soccer players now than in 2001, according to research from Sweden.

Minimalist footwear, shortened stride affect loads differently during running

Running in minimalist footwear and running with a shorter stride length are both associated with reduced knee loads, but the two approaches differ in their effects on loading at the ankle, according to research from the University of Calgary in Canada.

Stability for CP: AFO use benefits diplegic children

In children with diplegic cerebral palsy (CP), wearing bilateral ankle foot orthoses (AFOs) that promote heel-first ground contact helps to improve stability and may reduce the risk of falls, according to research presented in March at the annual meeting of the American Academy of Orthotists and Prosthetists (AAOP) in Orlando, FL.

Shifting position of shoe heel rocker affects ankle mechanics during gait

Varying the placement of a shoe heel rocker affects walking gait kinematics, even when the toe rocker placement is kept constant, according to research presented in March at the annual AAOP meeting in Orlando, FL.

Kinematics at foot, not shank, respond to increases in heel-sole differential

Elevating the heel of a shoe significantly affects foot kinematics but not shank kinematics during gait, according to research from the UK presented in March at the annual AAOP meeting in Orlando, FL.

Benefits of balance: YBT is associated with history of injury

Deficits in single-leg balance may contribute to the high rate of injuries among endurance athletes, but hip strength may not, according to two studies presented in February at the American Physical Therapy Association’s annual Combined Sections Meeting in Anaheim, CA.

Clinically useful 2D measurements predict patellofemoral joint force

Researchers from East Carolina University (ECU) in Greenville, NC, have identified 2D lower extremity kinematic measurements that accurately predict patellofemoral joint (PFJ) force during running and can be used clinically to identify runners at risk of injury.

Extension correction: AFO design improves PTTD mechanics

When a lamp cord doesn’t quite reach an outlet, you reach for an extension cord. So when a custom ankle foot orthosis (AFO) didn’t quite provide the corrected forefoot abduction desired in patients with post­erior tibial tendon dysfunction (PTTD), researchers from Syracuse, NY, added a lateral extension.
