Gait study finds FES of plantar flexors fails to improve mechanical recovery

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

Diabetic boot bests TCC for offloading forefoot area but not for ulcer healing

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

Effects of prosthetic gel liner thickness on pressure lack statistical significance

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

Lateral loading during cutting affects perceptions of turf shoe performance

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

Even motion control footwear allows midfoot movement while running

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

Study finds hormones, fatigue affect ankle ligament laxity in female athletes

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

A twist in ACL-OA link

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.

Saving limbs at home

Studies spotlight American outcomes
For years, the amputation prevention literature has been dominated by studies performed outside the United States. Two recent studies, however, have served notice that that trend is starting to change.
