Shoe effects on tibial rotation vary
Research from the U.K. published this month suggests that motion control running shoe technology can help decrease tibial internal rotation during running, theoretically decreasing the risk of proximal symptoms such as those associated with iliotibial band syndrome or patellofemoral pain syndrome.

The positive effects of a training program on adductor-related groin pain are still evident up to 12 years later, according to a Danish study. Researchers from Copenhagen University Hospital in Amager, Denmark, assessed the long-term effects of training eight to 12...
Two recent studies cast doubt on the merits of whole body vibration training, as either a replacement or an adjunct to conventional training, for improving jump performance. Researchers from Springfield College in Massachusetts found that WBV training and conventional...
Other factors may warrant focus
Research presented in August at the annual meeting of the American Society of Biomechanics in Long Beach, CA, adds support to the increasingly popular idea that patellofemoral pain syndrome arises from different mechanisms—and therefore should be managed differently—in different subgroups of patients.

Just because a runner’s foot strike pattern changes as a result of switching from shod to barefoot running doesn’t necessarily mean that runner will experience lower impact loading rates, according to research from the University of Oregon presented in August at the ASB meeting.
Female athletes may have a greater risk of a primary anterior cruciate ligament injury than their male counterparts, but following ACL reconstruction both genders are equally prone to asymmetrical landing kinetics that could lead to a second injury, according to research from Cincinnati Children’s Hospital.
Some surgeries may predict AC lesions
Research presented this month at the annual meeting of the American Orthopaedic Society for Sports Medicine spelled more bad news for advocates of meniscectomy, potentially linking the embattled procedure to the development of articular cartilage lesions that can progress to osteoarthritis.
Gender appears to affect patterns of hamstring injury in soccer, suggesting that different prevention strategies may be in order for male and female players, according to a study presented in June at the National Athletic Trainers Association meeting. Researchers from...
A preseason evaluation of the New York Giants football team found that nearly all players suffered from vitamin D insufficiency, a factor that may have contributed to muscle injuries, according to a study presented this month at the AOSSM meeting. Researchers from...
Anterior stiffness may be a key differentiator between people who develop chronic instability following an ankle sprain and those who recover fully, according to research presented in June at the annual meeting of the National Athletic Trainers Association....
Revised approach may be needed
Patients with chronic ankle instability demonstrate impaired plantar sensation but, surprisingly, do not exhibit increased ligament laxity, according to two studies presented in June at the annual meeting of the American College of Sports Medicine.
Lateral mobility of the patella is associated with patellar tendinopathy and may be a key determinant of whether an at-risk athlete develops PT as opposed to patellofemoral pain syndrome, according to research from the University of California, San Francisco presented...
A single sports season of neuromuscular training is not long enough for athletes to have retained any adjustments to landing technique three months later, according to a study from the University of North Carolina at Chapel Hill presented in June at the ACSM meeting....
Physical exam could be used to screen
Physical exam findings including hip range of motion can be used to help screen athletes for femoroacteabular impingement even before symptoms occur, according to research presented in February at the annual meeting of the American Academy of Orthopaedic Surgeons.
A Canadian meta-analysis presented at the AAOS meeting confirms that early mobilization after Achilles tendon rupture essentially negates the difference in re-rupture rate between operative and nonoperative treatments. Most meta-analyses of operative vs nonoperative...
