Study confirms neuromotor alterations in runners with Achilles tendinopathy

A recent study done at the University of Melbourne in Australia supports the theory that, in runners with Achilles tendinopathy (AT), altered neuromotor recruitment patterns of the triceps surae create differential intratendinous loads that lead to pathology.

Off balance: Instant total contact casts create instability

Instant total contact casts (iTCCs), which add length and weight to the involved leg, perturb balance in healthy individuals and could increase fall risks in the already–balanced challenged population of individuals with diabetic peripheral neuropathy.

Ulcer location influences healing times, from shortest at toes to longest at heel

A study e-published February 7 by Diabetes/Metabolism Research and Reviews found that time to diabetic foot ulcer healing was dependent on location, increasing progressively from toe to midfoot to heel, but did not differ between plantar and nonplantar ulcers.

Diabetes, cognitive deficits impair gait in older adults, but neuropathy does not

Type 2 diabetes affects gait parameters in older adults, and impaired cognition further reduces performance, according to investigators from Ghent University in Belgium who studied 101 patients living in community and residential care settings.

Decoding Loading: In vivo data recast shoe–OA discussion

A German study of individuals with instrumented knee implants suggests the actual effects of footwear on loading in patients with knee osteoarthritis (OA) may be much more subtle than those reported in previous studies using indirect measures of load.

Drop foot fix for CMT: AFOs work both proximally and distally

The mechanism by which ankle foot orthoses (AFOs) reduce drop foot in patients with Charcot-Marie-Tooth disease (CMT) involves proximal effects as well as the distal changes with which clinicians are more familiar, according to research from the UK.

Motion-control footwear features fail to decrease knee adduction moment

Two studies e-published in October found medial arch supports and motion control shoes have no significant effect on knee adduction moment (KAM), regarded as a surrogate measure of medial knee compression.

Brains and sprains: Is there an extremity-concussion link?

The sports medicine community is demonstrating increasing interest in the possibility that neurocognitive impairment and musculoskeletal injury may be related, as evidenced most recently by an exchange in the letter to the editor section of the September issue of The American Journal of Sports Medicine (AJSM).

Achilles tendon in runners maintains stiffness despite stress of marathon

Running a marathon does not significantly affect Achilles tendon stiffness, suggesting that overuse may not explain Achil­les ruptures in runners, according to a Finnish study published in the October issue of the Journal of Experimental Biology.

Midfoot index of load differentiates postarthrodesis gait from normal

Swiss researchers have found that pedobarographic differentiation between ankle arthrodesis patients and healthy volunteers can be narrowed down to a single variable, midfoot index of load—a finding that could make the technology much more accessible to the average clinician.
