Kickboxing: A creative approach to improving balance in patients with MS

Kickboxing isn’t just for elite martial artists. In fact, preliminary research suggests the kicks, punches, and knee movements associated with the sport can improve balance and mobility in patients with multiple sclerosis. And as an added bonus, it’s also fun.

Out on a limb: Well heeled

It’s widely believed that women persist in wearing high-heeled shoes, despite what can be considerable discomfort, for aesthetic reasons. But what if, on some level, we’re attracted to high-heeled shoes because we associate them with social status?

Teachings from the East

Researchers and practitioners from across the globe came together in Hyderabad, India, in February for the World Congress of the International Society of Prosthetics & Orthotics (ISPO). LER’s exclusive coverage of the 2013 World Congress, held in India for the first time, explores the evidence-based use of lower extremity devices for conditions ranging from stroke to cerebral palsy to diabetes.

CEREBRAL PALSY: Dynamic devices facilitate compliance, outcomes in children with cerebral palsy

Brace wear time, not torque, is key – Dynamic orthoses offer an effective alternative to static devices for management of tip-toe gait and knee flexion contracture in children with cerebral palsy (CP), particularly because the dynamic devices are associated with greater compliance, according to separate studies from Sweden and France.

OSTEOARTHRITIS: Knee braces and wedged insoles both alter gait in patients with knee OA

A Taiwanese study offers more evidence that offloading knee braces and wedged foot orthoses are both associated with significant biomechanical improvements in patients with knee osteoarthritis (OA).

SPORTS MEDICINE: Proximal rocker bar on shoe can relieve tension on Achilles tendon in runners

A rocker bar proximally positioned on a running shoe can relieve tension on the Achilles tendon as well as reduce the force required of the calf muscles during walking and slow running, according to research from the Netherlands.

DIABETES: More results support use of foot orthoses to significantly decrease plantar pressures

Swedes also find low ulceration rate – Research from Sweden and Egypt provides more evidence that foot orthoses can significantly decrease plantar pressures in patients with diabetes, theoretically reducing the risk of foot ulcers and lower extremity amputation.

FLAT FOOT: Arch structure in children with talipes planovalgus improves with shoe inserts

Orthotic management of pediatric talipes planovalgus starting at an early age is associated with significant improvement in weightbearing arch structure, according to research from Saga University in Japan.

OFFLOADING: Walkers’ effect on proximal biomechanics varies depending on design characteristics

Tibial inclination appears significant – Orthotic walkers have significant effects on proximal joint mechanics during gait, the extent of which appear to depend on individual device design, according to research from the University of Central Lancashire in the UK.

PEDIATRICS: In hyperpronators, functional scoliosis responds to distal orthotic treatment

What appears to be idiopathic scoliosis may actually be functional scoliosis that can be effectively treated with foot orthoses in children who are hyperpronators, according to research from Chungnam National University in Daejeon, South Korea.

STROKE: Eight weeks of early AFO use significantly enhances benefits of stroke rehabilitation

Functional balance test scores rise – Use of an ankle foot orthosis (AFO) within six weeks of stroke results in better balance outcomes and earlier independent ambulation than if AFO use is delayed, according to research from the Netherlands.

Active Stance: Rethinking the concept of excessive pronation

Anterior knee pain is one of the most common injuries affecting runners, accounting for 25% of all running injuries.1 The etiology of anterior knee pain is multifactorial in nature,2 but one of the most commonly cited biomechanical risk factors is excessive rearfoot pronation.

Foot ulcer experts weigh use of hyperbaric oxygen

Two February publications sum up the polarizing nature of hyperbaric oxygen therapy (HBOT) for treating recalcitrant diabetic foot ulcers. A meta-analysis supported use of HBOT, while a large cohort study found a lack of effectiveness in community-care settings.

Exercise helps reduce claudication symptoms

Research suggests that exercise therapy can help reverse the ambulatory impairments associated with lower extremity pain in patients with peripheral arterial disease. The next step is to determine the methods of exercise therapy most likely to result in optimal outcomes.

The role of varus thrust in knee osteoarthritis

Varus thrust is a characteristic of dynamic alignment that has been shown to be predictive of medial tibiofemoral structural progression. Treatments aimed at minimizing varus thrust may reduce structural progression and symptoms related to knee osteoarthritis.

Foot orthoses and injury prevention in football

Team practitioners at the United States Naval Academy designed an orthotic intervention to prevent turf toe and Lisfranc sprains in football linemen and gained valuable insights about how players’ preferences and predispositions can affect compliance.

Bad breaks: Fifth met fractures can curtail NFL careers

Jones and proximal diaphyseal fifth meta­tarsal fractures are common among football players and may shorten their athletic careers, according to a February study that found players with fractures were significantly more likely than players without the injuries to have played in fewer than 10 National Football League (NFL) games.

Even gradual transition to minimalist running leads to signs of stress in feet

Investigators at Brigham Young University in Provo, UT, reported that runners who transitioned from traditional running shoes to zero-drop shoes meant to mimic barefoot running had evidence of bone marrow edema, a marker for stress on the foot, after gradual transition from conventional to minimalist shoes.

Girls, football players face highest risk of knee injury in high school athletics

The highest knee injury rates in US high school sports are associated with football, followed by girl’s soccer and gymnastics, according to an epidemiological study from The Ohio State University in Columbus and Colorado State University in Aurora.
