The Throw – From Below: Hip mechanics dictate overhead motion

It’s shoulder and elbow injuries that most often land baseball pitchers and other throwing athletes on the disabled list. But the cause of those injuries often can be traced to strength and flexibility deficits at the hip—effects that reverberate up the kinetic chain.

Publisher’s memo: The first of many

When I decided to create LER, I spoke with many of you to determine if there was a need for a multi-disciplinary magazine exclusively focused on the lower extremity. The response was overwhelming and very positive. You wanted a practical, easy-to-read publication that delivered the clinical literature reviews but without all the dry and boring details of the methods, a publication that encouraged collaboration and helped to improve outcomes for your patients.

Out on a limb: Personality test

Athletes are known for being difficult patients, with psychology often playing as important a role as biomechanics. The objective is to keep an athlete’s personality from getting in the way of proper medical care. But sometimes that’s easier said than done. Just ask the Boston Red Sox.

Quantifying functional effects of AFO alignment

Assessing device alignment is a key aspect of prosthetic practice, but when it comes to lower extremity orthotics the process is less common. That’s changing, however, as researchers begin to document the effects of alignment on gait biomechanics.

Knee OA and obesity: A cyclical clinical challenge

Obesity not only increases the risk of knee osteoarthritis but also makes it more difficult to treat, as typical exercise recommendations often are simply not practical. Gait researchers, however, are working to identify new potential therapeutic approaches.

Therapeutic management of flexible flatfoot pain

The practitioner’s objective in treating flexible flatfoot is to realign the foot and eliminate pain. Multiple nonsurgical therapeutic options are available, but if those are unsuccessful, surgical interventions can be effective.

Dyslipidemia’s effect on diabetic neuropathy

The importance of glycemic control in patients with diabetes is well known. But neurological studies suggest that dyslipidemia is actually a more significant contributor to the development of peripheral neuropathy in the same patient population.

Fighting fatigue

As a growing body of research supports the idea that fatigue contributes to sports-related injury, investigators are now working to identify those athletes who may be most vulnerable to the effects of fatigue and interventions that could counteract those effects.

Charcot and limb loss

Ulcer prevention is the key to amputation prevention in patients with Charcot arthropathy, according to research from Chicago that raises the question of whether pre-emptive surgical correction of deformities is warranted in Charcot patients.

Habitual high-heeled shoe wearers exhibit musculotendinous changes

Women who are so accustomed to high heels that they feel uncomfortable in flat shoes demonstrate musculotendinous changes compared to those who prefer flats, according to research from Manchester Metropolitan University in the U.K. Investigators recruited 11 women between the … Continue reading

Altered ability to detect joint loading plagues chronically unstable ankles

Even in the absence of impaired joint laxity, chronically unstable ankles demonstrate a reduced ability to detect afferent signals in response to applied loads, according to research from the University of Delaware. In 19 healthy ankles and 10 ankles with … Continue reading

Study finds variations in co-contraction during closed kinetic chain exercises

Closed kinetic chain exercises vary considerably with respect to quadriceps-hamstrings co-contraction, which may have significant implications for rehabilitation, according to research from the University of North Carolina in Chapel Hill. Investigators analyzed activation of the vastus medialis, vastus lateralis, medial … Continue reading

Investigators examine biomechanical effects of carbon composite devices

AFOs must find energy balance – The extent to which carbon composite ankle foot orthoses improve gait efficiency in stroke patients may be a function of walking speed, according to a Swedish study. And despite the fact that the devices are known for their energy storage, research from the Netherlands suggests that the relationship between energy storage and energy cost may be complicated.

Obesity impairs children’s response to orthotic therapy for flexible flatfoot

Is earlier intervention needed? Researchers and clinicians are only beginning to understand the relationship between pediatric flexible flatfoot and obesity, which becomes even more complicated in the context of orthotic treatment. Findings from Hong Kong appear to throw another wrinkle into the mix, suggesting that obese children are significantly slower to respond to orthotic therapy than their normal-weight counterparts.

Researchers explore screening options for earlier diagnosis of Charcot foot

Biomechanics may offer clues – Too often, by the time Charcot neuroarthropathy is diagnosed, it is too late to do much more than accommodate the resulting deformity. That’s why researchers from Germany and the U.K. are working to find ways of screening for patients at risk for Charcot, which would facilitate earlier and more effective intervention.

Studies confirm effect of knee bracing on OA symptoms, joint adduction moment

But placebo findings raise questions – Three German studies presented at the ISPO meeting in Leipzig confirm that bracing for knee osteoarthritis is associated with both symptom improvement and biomechanical effects. But the findings also suggest that the relationship between those two sets of outcome measures is more complicated than one might think.
