National Biomechanics Day continued to build momentum in its second year, as scientists from Delaware to New Zealand got a jump on recruiting the next generation of biomechanists by demonstrating a wide range of applications—not to mention just how much fun the field can be.

Lower extremity stress fractures are not limited to members of the armed forces, but have been studied extensively in military populations. That body of evidence has important implications for stress fracture prevention and management in runners, other athletes, and even nonathletes.

Research suggests light touch sensation in the foot and ankle may be negatively affected several years after anterior cruciate ligament (ACL) reconstruction—a finding consistent with studies that have reported decreased somatosensation in patients with other lower extremity conditions.

The low-volume shoes worn by cyclists, figure skaters, and others can make orthotic management of these patients challenging. So, lower extremity practitioners have had to develop creative strategies for achieving the desired biomechanical effects while working within a limited space.

A multidisciplinary joint replacement program is improving patient outcomes, decreasing complications, and shortening hospital stays, which helps to lessen clinical anguish following total knee arthroplasty as well as the financial burden on patients and the healthcare system.

Although it has not been shown to be a risk factor for stress fracture in traditional running, the presence of Morton’s foot (a second metatarsal longer than the first) alters running mechanics in ways that may exacerbate the risks of forefoot injury associated with alternative running styles.

Uncontrolled deformity, deep infection, and ischemia-hypoxia make up the troublesome triad of confounders associated with healing challenges in patients with diabetic foot ulcers. Clinical examination and intervention in nonhealing patients should focus on these three elements.

Footwear with rocker soles are best known for helping to redistribute plantar pressures during gait in patients with diabetes, but research suggests they also have clinically relevant effects on balance and gait that can be beneficial for some populations but potentially dangerous for others.

Using patient-reported outcome tools can give lower extremity clinicians insight into the disability experienced by patients with chronic ankle instability. A combination of instruments may be necessary, as different assessments may capture different aspects of the condition.
By Adam B. Rosen PhD, ATC; and Cathleen N. Brown PhD, ATC Continue reading
Prescription of foot orthoses for runners with patellofemoral pain (PFP) is often based on the premise that individuals with excessive pronation are among those most likely to have a positive response. However, preliminary analyses indicate this may not be the case.
By Thomas Gus Almonroeder, DPT; and John Willson, PT, PhD Continue reading
The growing popularity of prehabilitation contrasts with mixed findings in the lower extremity literature: Specifically, the approach seems to be more effective in patients undergoing anterior cruciate ligament (ACL) reconstruction than those undergoing hip or knee replacement.

Running may increase the risk of knee osteoarthritis (OA) onset or progression for some people, but in many others the knees will be safe during running; in such individuals, the benefits of physical activity can positively affect weight management and other means of reducing OA risk.
By Nicole M. Cattano, PhD, LAT, ATC; and Jeffrey B. Driban, PhD, ATC, CSCS Continue reading
Even patients who obediently wear their O&P devices can pose a clinical challenge if they wear their devices past the point of breakdown. Experts offer suggestions for dealing with patients who are hard on devices—including those who are very large, very active, or very frugal.

Several confounding factors make it difficult to determine statistical associations between footwear and injuries in basketball, but attitudes toward shoes among National Basketball Association (NBA) players suggest both positive and negative trends with regard to potential injury risk.

To understand the association between jumping biomechanics and transmission of forces through the patellar tendon, practitioners must have a working knowledge of the anatomy of the knee, as well as the biomechanical factors that determine force transmission through the knee.
By Rob Halle, PT, DPT, OCS, CSCS Continue reading
As evidence accumulates suggesting negative effects of depression, dementia, and other mental health issues on gait and foot-related outcomes in people with diabetes, researchers are looking at ways to screen for risk factors and psychosocial issues earlier in the continuum of care.

Although most clinicians tend to emphasize hip abductor and external rotator muscle strengthening in injury prevention and rehabilitation, recent research suggests exercises to increase explosive hip extensor strength may be critical for controlling frontal plane motion during cutting tasks.
By Marc Norcross, PhD, ATC, and Sam Johnson, PhD, ATC Continue reading
Inertial measurement units (IMUs) facilitate the creation of a gait analysis system that is portable and suited for use in the clinic. Research suggests IMUs can be used to measure clinically important gait metrics in children with cerebral palsy, which may improve patient outcomes.

As ciprofloxacin and other fluoroquinolones are prescribed more frequently, tendon-related adverse effects are also becoming more common. Experts often do not recommend these drugs, particularly for athletes or elderly patients, and emphasize that all patients should know the risks.
By Barbara Boughton Continue reading
Although not as common as Achilles tendinitis, peroneal tendinitis is seen in a certain group of patients with chronic ankle instability or with a cavovarus foot.1 Peroneal tendinitis presents as lateral foot pain and may also be of unknown etiology or associated with an acute inversion injury.
By Patricia Pande, MClScPT, CSCS, CPed Continue reading
Decisions related to the stiffness of an ankle foot orthosis (AFO)—whether they involve device design or the materials from which it’s fabricated—can help lower extremity clinicians customize stability, biomechanics, and muscle function to meet individual patients’ needs.

Professional football players are enduring higher levels of force than ever, and foot and ankle injury rates are increasing as a result. Advances in surgery and rehabilitation have helped get players back on the field more quickly, but injury prevention remains a significant challenge.
By Will Carroll Continue reading
Altered biomechanics after ankle arthrodesis often increase stress on the adjacent joints in the foot, which can cause or exacerbate osteoarthritic degeneration in those joints. Clinicians and researchers are working to better understand this process and how to minimize patients’ risk.

The ability to identify and treat patients at risk for mental health issues after anterior cruciate ligament (ACL) injury may help improve psychological readiness for reconstructive surgery, attitudes toward postoperative rehabilitation, and successful surgical and rehabilitation outcomes.

Pronation is a triplanar movement and is the combination of rearfoot eversion, midfoot abduction, and talocrural dorsiflexion.1 Pronation in normal gait allows flexible, adaptive changes to varying types of terrain; it dissipates ground reaction forces; and encourages lower extremity internal rotation.
