As researchers explore the possibility that idiopathic toe walking has an underlying neurologic cause, clinicians continue to refine treatment strategies to keep ITW patients off their toes. Orthotic devices play a key role, with lower-profile devices growing in popularity.

Inconsistent findings from laboratory studies have made it difficult to determine which gait alterations are specific to diabetic peripheral neuropathy and which also affect diabetic patients without neuropathy. Body-worn sensor technology may help clarify the distinctions.

Experts still disagree about whether stretching prior to athletic activity can prevent injury and, if so, whether those benefits offset any negative performance effects. But they do tend to agree that some form of stretching is probably a good idea for most athletes.

Dose-response research refutes the common perception that increasing brace wear time leads to muscle atrophy in patients with knee osteoarthritis. In fact, longer bracing duration appears to improve hamstring strength as well as increasing patients’ physical activity levels.

Exercise is the standard prescription for obesity. But alterations to joint biomechanics, gait, and anatomical structure in overweight children and teens mean that physical activity comes with its own risks, which practitioners must factor into any clinical recommendations.

Contrary to the conclusions of early research, recent studies suggest that arch height does indeed affect lower extremity function. The biomechanics associated with different arch heights may provide a basis for treatment and prevention of related injuries.

Gauntlet-style ankle foot orthoses offer an alternative to a larger rigid thermoplastic AFO for foot and ankle pathologies requiring more stability or immobilization than a foot orthosis provides. Materials, trim lines, and fabrication techniques can vary to meet different patients’ needs.

A convergence of comorbidities means diabetic patients on dialysis have an even higher risk of foot ulcers and amputation than those without renal disease. The potential for preventing these complications at dialysis centers is too often underappreciated by practitioners.

This two-part series examines the link between ACL injury and the later development of osteoarthritis (OA) and how surgery may strengthen or weaken that link. This second installment explores meniscal damage, proprioception, and what MRI can add to the discussion.

New evidence-based guidelines on the management of diabetic foot infections reflect significant advances by researchers and clinicians, but the recent emergence of regulatory hurdles has slowed the development of new antibiotic drugs for treating those infections.
By Emily Delzell
Different foot strike patterns are associated with different means of attenuating and redistributing forces during running, which may have implications for injury risk and rehabilitation. Researchers, however, have yet to fully examine and understand those implications.
By Peter Larson, PhD
Too many knee braces just won’t stay put, which can affect compliance and possibly even device effectiveness. Research on the topic is scarce, but experts say the key to minimizing knee brace migration is making sure the device fits the patient’s anatomy as closely as possible.

A growing body of research suggests that footwear comfort can improve movement performance and, in particular, neuromuscular control of balance. These findings could have significant implications for rehabilitation of older adults and patients with lower extremity disorders.
By M. Owen Papuga, PhD, and Jeanmarie R. Burke, PhD
Ankle braces help prevent injury by restricting motion, but those restrictions don’t necessarily result in negative effects on athletic performance. Evidence suggests that while agility may be affected with use of an ankle brace, vertical jump and balance skills may not.

Studies assessing the relative functional benefits of limb salvage and amputation for lower extremity bone and soft tissue tumors have produced inconsistent results, but the range of subjective and objective tests used in those studies may have influenced the findings.
By Lucy Kupersmith, BA, and Jeremy S. Somerson, MD
For the majority of evolutionary history, runners were either barefoot or wore minimalist footwear lacking the cushioning of today’s running shoes. Barefoot or minimally shod runners demonstrate differences1 in kinematics and impact forces compared with those wearing modern running shoes, and some research suggests barefoot running may confer biomechanical advantages over more cushioned footwear.

Hamstring injuries that occur during sprinting are a significant concern in football, not just because of the frequency with which they occur, but also because they are notoriously difficult to rehabilitate, which underscores the need for effective prevention through targeted exercise programs.
By Charles D. Kenyon, MS, RSCC, and Marcus C.C.W. Elliott, MD
Not all patients with diabetes and not all ulcerated limbs are amenable to salvage. When salvage is not an option, amputation can help improve patient function, but a number of factors should be considered when deciding how much of the foot—if any—should be retained.

A delay in the activation of the peroneus longus and peroneus brevis muscles is thought to contribute to the risk of inversion ankle sprain. New research suggests that ankle taping, in addition to providing mechanical stability, also helps reduce this peroneal latency.
By Adam Knight, PhD, and Wendi Weimar, PhD
Evidence suggests that the prevalence and symptom severity of knee osteoarthritis are greater in African-American patients, underscoring the need for lower extremity practitioners to implement effective strategies for disease prevention and management in this patient population.
By Kelli D. Allen, PhD
A patient presenting with both end-stage knee osteoarthritis and a painful foot-ankle deformity is not uncommon, but the medical literature offers practitioners little guidance as to which condition should be managed first or whether they should be addressed simultaneously.
by Michael S. Pinzur, MD, and William Hopkinson, MD
Advances in communications technology now make it possible for an expert in one location to assess a diabetic foot ulcer in a patient who is miles away. But telehealth efforts face a number of hurdles, the most daunting of which may be patient privacy.
By Emily Delzell
When prescribing an ankle foot orthosis or neuroprosthesis for a patient with acute drop foot following stroke, lower extremity practitioners should consider the device’s potential effects on neural plasticity and motor relearning in addition to its potential effects on gait.
By Chad Lairamore, PhD, PT, CBISt
Newly published proceedings of an interdisciplinary osteoarthritis summit hosted by the Hospital for Special Surgery explore how researchers are working to understand the complexities of the disease and break down the barriers facing the development of new interventions.
