Wearable sensors assess relationship between foot problems and frailty
Assessing how foot problems— namely, pain, neuropathy, and deformity— contribute to frailty syndrome has been a challenge for researchers, as transporting frail elders to lab facilities creates its own set of issues. But a recent study from the University of Arizona used wearable sensors to assess the seniors in their “natural” environment and found significant relationships between the number of foot problems and degree of frailty.

Three-year follow-up: Close contact casting vs surgery
In a pre-specified, 3-year extension of a randomized clinical trial of equivalence, close-contact casting maintained equivalence in function compared to surgery in older adults with unstable ankle fracture. Furthermore, no significant differences were reported in quality of life or pain. The authors concluded that the focus of treatment for these patients should be on obtaining and maintaining reduction until union, using the most conservative means possible. Continue reading

Lower-extremity amputation feared more than death
Both type 1 and type 2 diabetes are known for their life-threatening complications—in particular, blindness from retinopathy, kidney failure, and peripheral neuropathy. For patients with diabetes and foot pathology, amputation is a significant worry. A recent study in Foot & Ankle Specialist sought to understand just how much this population fears lower-extremity amputation (LEA).

Wasp stings: Some really do hurt more than others, and how to counsel patients
As summer approaches and we become more active outdoors, wasps will become more active, too. Two recent studies highlight the pain and danger of the ubiquitous wasp. The first study, from entomologists at the University of Utah, looked at stinger length compared to reported pain and toxicity.1 Continue reading

Flip flops, bare feet, or sports shoes: Which are best and which are worst?
Many have long suspected the answer, but a new study would appear to resolve the question: Are flip flops really that bad for your feet? According to Chen and colleagues from the Department of Biomedical Engineering at The Hong Kong Polytechnic University, flip flops are most likely no better than barefoot when it comes to lower-limb co-contraction and joint contact force in the ankle.

Treatment for post-stroke spastic equinovarus and plantar flexor spasticity
Spasticity occurs in 20% to 40% of stroke patients. Two new studies add to the body of evidence supporting the use of botulinum toxin type A (BT-A) injections for post-stroke spasticity: the first looked at the ideal timing of injections for plantar flexor spasticity, and the second looked at ultrasound-guided injections for spastic equinovarus.

Crossover prosthetic design
Prosthetic feet are typically optimized for a narrow range of activities, meaning active prosthetic users may need more than 1 prosthesis to fully participate in activities with varying degrees of impact. Modern energy-storing feet (ESF) support users’ ability to walk at differing speeds, as well as support static standing, but they can limit aerobic activities and running speeds. Running-specific feet (RSF), while ideal for running and sprinting, do not support low impact activities, particularly standing or walking. Continue reading

Post-operative complications after Achilles tendon rupture repair
Achilles tendon rupture (ATR) is one of the most common injuries resulting from sports and exercise activities. Its resulting functional deficits can last more than 2 years from the original injury. While traditionally it has been an injury seen more among men, prevalence among women has been increasing, most likely due to increased participation in recreational sports. Continue reading

Low-cost trans-femoral prosthesis uses plantar insole sensors
Indian researchers have designed a trans-femoral prothesis with plantar insole sensors that they found allow users to achieve near able-bodied gait kinematics. The passive prosthesis uses a magneto-rheological (MR) damping system with electronic control based on plantar insole feedback Continue reading

Supportive footwear for children with CMT
The effect of footwear on gait and balance of children and adolescents with Charcot-Marie-Tooth (CMT) disease is of interest to parents and clinicians. Children with CMT, which causes progressive damage to peripheral nerves, particularly the feet and ankles, often have gait difficulties due to muscle weakness, including problems with balance, resulting in falls.

Study finds little difference between DMO and PMO for hallux valgus
Guiding patients to make the most appropriate choice among options to correct hallux valgus has long been a challenge: Distal metatarsal osteotomy (DMO) is liked for its shorter incision, low level of invasiveness, lower complication rate, and its ability to improve pain and functionality across a wider range of deformities.

Foot pain, ill-fitted footwear increase risk of falls in elderly
Foot pain and poor-fitting footwear are among the well-known risk factors for falls among the elderly. Two new studies from Spain sought to quantify the significance of these issues in the elderly by looking at lesser toe deformities (LTD) in a general population, and footwear fit among those with Alzheimer’s disease. Continue reading

Reliability of FPI-6 in older adults warrants caution
Because it uses 6 items to quantify and classify foot pressure, the Foot Pressure Index-6 (FPI-6) is considered a more complete measure than many others. The FPI-6 has been validated for use with adults aged 18 to 57, where it can play a role in identifying risk factors for sports and training injuries. Continue reading
