Barefoot running seems a solution By Jordana Bieze Foster Despite what you may have heard, researchers are a long way from proving that barefoot runners are less prone to injury than those who run in shoes. But data presented at … Continue reading
Gait speed linked to braking force By Jordana Bieze Foster Rigid ankle foot orthoses increase gait speed in hemiplegic stroke patients, but not for the reasons one might think, according to research from the Kessler Foundation Research Center in New … Continue reading
Fall simulations help AK amputees By Jordana Bieze Foster Thanks to an improved ability to simulate falls in the laboratory, researchers are identifying variables that contribute to falls in above-knee amputees and implementing training programs to improve response to tripping. … Continue reading
Robot-assisted ankle rehabilitation significantly improves functional mobility in stroke patients, according to research from Northwestern University in Chicago. Researchers customized a continuous passive motion machine to create a portable rehabilitation robot that is used for both passive stretching and active … Continue reading
Functional electrical stimulation of the plantar flexor muscles in addition to the dorsiflexors surprisingly had no effect on mechanical recovery during post-stroke gait in a study performed at the University of Delaware. Researchers analyzed the effects of dorsiflexion FES alone … Continue reading
A cast-boot ankle foot orthosis decreases plantar pressures under the forefoot more effectively than a total contact cast, but its relative effectiveness for ulcer healing is still a function of compliance, according to research from Washington University in St. Louis. … Continue reading
The choice of a thick or thin gel liner in transtibial amputees may ultimately come down to personal preference, according to research from Northwestern University in Chicago. Investigators compared two prosthetic gel liners, one 3 mm thick and one 9 … Continue reading
A football player’s perception of a shoe may be related to the amount of lateral loading associated with that shoe during cutting, according to research from Cincinnati Children’s Hospital. Investigators analyzed cutting movements in 17 male teenaged football players as … Continue reading
Practitioners who recommend so-called motion control running shoes may want to think of “control” as a relative term, in light of research demonstrating significant sagittal plane movement of the foot within motion control shoes. Investigators from Northern Arizona University in … Continue reading
A tennis-specific version of the neuromuscular training program developed in Cincinnati could significantly improve performance on the court, according to research published in the September issue of the Journal of Strength and Conditioning Research. The Sportsmetrics training program developed by … Continue reading
Much of the literature on hormones and ligament laxity has focused on the knee, but a study from James Madison University suggests that an interaction between hormone levels and fatigue may also affect laxity at the ankle. Researchers analyzed ankle … Continue reading
Studies clash over surgery’s significance
In the wake of a Dutch report that surgery does not decrease the risk of radiographically diagnosed osteoarthritis following anterior cruciate ligament injury, research presented in July identified preoperative variables that could predict the development of OA after ACL reconstruction.
Plus: • Hamstring injuries • Hip screening
Key variables predict response
Prefabricated foot orthoses improve the ability to perform weight-bearing knee flexion tasks in patients with patellofemoral pain, according to research from La Trobe University in Australia.
Plus: • Lacing techniques • Fatter, flatter feet
As a growing body of research supports the idea that fatigue contributes to sports-related injury, investigators are now working to identify those athletes who may be most vulnerable to the effects of fatigue and interventions that could counteract those effects.
Ulcer prevention is the key to amputation prevention in patients with Charcot arthropathy, according to research from Chicago that raises the question of whether pre-emptive surgical correction of deformities is warranted in Charcot patients.
Women who are so accustomed to high heels that they feel uncomfortable in flat shoes demonstrate musculotendinous changes compared to those who prefer flats, according to research from Manchester Metropolitan University in the U.K. Investigators recruited 11 women between the … Continue reading
A study from the University of Tennessee supports the use of a three-quarter length custom orthosis for patients with hallux valgus deformity. The study compared custom orthoses of full, three-quarter, and sulcus lengths. The orthoses were worn by 25 patients … Continue reading
Even in the absence of impaired joint laxity, chronically unstable ankles demonstrate a reduced ability to detect afferent signals in response to applied loads, according to research from the University of Delaware. In 19 healthy ankles and 10 ankles with … Continue reading
Closed kinetic chain exercises vary considerably with respect to quadriceps-hamstrings co-contraction, which may have significant implications for rehabilitation, according to research from the University of North Carolina in Chapel Hill. Investigators analyzed activation of the vastus medialis, vastus lateralis, medial … Continue reading
After more than a decade of discord and sometimes contentious debate, biomechanists appear moving toward a consensus that the mechanism of anterior cruciate ligament injury cannot be wholly attributed to either the frontal or sagittal planes but is in fact multiplanar.

Net gain for ankle bracing – Rigid and semi-rigid ankle braces may help prevent inversion ankle sprains in female volleyball players with no previous history of sprain, according to research published in the April issue of Foot & Ankle International. Plus: • Neuropathyandgait • Partialweightbearing • Erratum
PTTD prognostication – Four variables, identifiable at an initial clinical evaluation, can help predict whether bracing will be successful in patients with posterior tibial tendon dysfunction, according to research from the University of Rochester Medical Center in Rochester, NY.

Two studies presented in March suggest that bracing for knee osteoarthritis may be effective in two patient populations that are not well represented in the OA bracing literature: those with lateral tibiofemoral compartment OA and those with severe disease.
