From amputee to clinical prosthetist: four journeys

A number of amputees, many inspired by the expert care they received after losing a limb, have been motivated to pursue careers in prosthetics, where they can provide patients with a unique and personal perspective. Four of these practitioners shared their stories with.

Running in an exerted state: mechanical effects

Kinematic and kinetic alterations in the lower extremities that researchers have observed during the course of a prolonged run may provide clinically relevant insights into patellofemoral pain and other conditions associated with a gradual onset of symptoms during exercise.

Post-polio syndrome: It takes a team approach

Along with technical issues related to muscle weakness, fatigue, and pain, the challenges of managing this hetero­gen­eous population include patients’ emotional response to the idea of needing an orthotic device for a disability they thought they had overcome.

Fifth met fractures and osteoporosis in women

Given that older women are at increased risk for osteoporosis, an increased incidence of fifth metatarsal fractures with increasing age in women suggests that such injuries could serve as an early point of entry into osteoporosis treatment and fracture prevention.

Cryotherapy and muscle recovery after exercise

Research utilizing contrast-enhanced ultrasound suggests that, although cryo­therapy effectively decreases the pain associated with exercise-related muscle damage, those symptomatic effects are not associated with decreased blood flow in the affected skeletal muscle.

Surface EMG: A how-to guide for practitioners

With evidence-based protocols in hand, practitioners can feel more comfortable clinically integrating surface electromyography (sEMG) assessment, creating more sophisticated sEMG treatment protocols, and demonstrating the effectiveness of interventions.

Running modifications to alter PFJ contact force

Patellofemoral pain interventions have increasingly focused on running technique and training approaches—such as utilization of a forefoot strike pattern, a shortened step length, and manipulations to training pace—to reduce patellofemoral joint loading parameters.

Researchers inch toward understanding of PTTD

In recent years, studies have elucidated aspects of the biomechanical effects of posterior tibial tendon dysfunction that may ultimately lead to improvements in treatment. But it isn’t always clear which factors contribute to PTTD and which
develop in response.

Vitamin D deficiency and risk of fracture in football players

Many US football players have lower than adequate serum vitamin D levels, but questions remain about the potential benefits of proactive treatment with supplementation to address vitamin D deficiency and reduce the risk of fracture in this
patient population.

Contributors to pediatric ACL surgery outcomes

Different factors influence outcomes after anterior cruciate ligament reconstruction in younger and older pediatric patients, but regardless of age, a delay to surgery is correlated with more severe additional injuries and the need for additional surgical procedures.

Iliotibial band syndrome and running mechanics

The mixed findings of several cross-sectional studies seem to suggest that no specific biomechanical variables are unequivocally associated with iliotibial band syndrome in either men or women, which underscores the importance of assessing each patient individually

Role of early rehab stages after ACL reconstruction

Traditionally, anterior cruciate ligament reconstruction outcomes have been assessed preoperatively and several months postoperatively, but new research suggests the early postoperative stages of recovery may also significantly affect self-reported outcomes.

Total ankle arthroplasty: defining its clinical niche

Research generally upholds total ankle arthroplasty as a viable alternative to the traditional first-line surgical treatment, ankle arthrodesis, for correctly selected patients with end-stage ankle arthritis. But complication rates associated with ankle arthroplasty remain an area of concern.

A long, frustrating search for plantar fasciitis relief

My husband Phillip and I used to live in Manhattan Beach, CA, a charming and affluent coastal town just south of Los Angeles. We resided two blocks from the wide, sandy beach. We took advantage of The Strand—a pair of concrete pathways that run for about two miles in front of many multimillion-dollar homes.

Conference coverage: 7th ACL research retreat

Anterior cruciate ligament injury experts met in Greensboro, NC, to examine the extent to which biomechanics and other less-familiar factors—including joint laxity, fatigue, neurocognitive function, and genetics—may contribute to noncontact injury risk.

Dual-task gait: The potential influence of orthotic devices

Clinicians know walking while performing a secondary task can be particularly difficult for elderly patients or those with neuromuscular impairments. But new research suggests the use of orthotic devices may improve dual-task gait, which could significantly improve quality of life.
