Changes in multi-segment foot biomechanics

Figure 1. The semi-custom mouldable Softec Response orthotic used in the current study. Background Semi-custom foot orthoses (SCO) are thought to be a cost-effective alternative to custom-made devices. However, previous biomechanical … READ MORE

AFO tuning: Balancing function and satisfaction

Tuning of ankle foot orthoses (AFOs) and AFO footwear combinations can significantly improve gait in patients with neuromuscular impairments. Even so, some patients still prefer their untuned devices, which has led researchers and … READ MORE

C. H. Riddell Family Movement Assessment Centre, Alberta Children’s Hospital

Movement abnormalities in children and adults are analyzed with advanced motion capture technology to aid clinicians with treatment decisions for patients with neurological diagnoses. This facility provides a range of healthcare … READ MORE

Dynamic compression for correction of pectus carinatum

We suggest that patients with pectus carinatum have a trial of compression therapy before recommending surgical resection. The use of pressure measurement avoids complications such as skin lesions, partial or poor results, and patient … READ MORE

Preliminary study of efficacy of dynamic compression system in the correction of typical pectus carinatum

Objectives This preliminary study evaluates, by qualitative score, the efficacy of the dynamic compression system (DCS) with a pressure-measuring device in the treatment of pectus carinatum (PC) as an alternative to surgery. Methods … READ MORE

Factors affecting patient compliance with compressive brace therapy for pectus carinatum

Lightweight, self-adjustable compressive brace designed for the treatment of pectus carinatum. Du-Young Kang, et al. Objectives The aim of this study was to identify factors affecting patient compliance with brace therapy for pectus … READ MORE

Does overgrowth of costal cartilage cause pectus carinatum?

A three-dimensional computed tomography evaluation of rib length and costal cartilage length in patients with asymmetric pectus carinatum. Figure 1. Measurement of the sternal rotation angle. The sternal rotation angle was measured as … READ MORE

Brace compression for treatment of Pectus carinatum

Background. Surgery has been the classical treatment of pectus carinatum (PC), though compressive orthotic braces have shown successful results in recent years. We propose a non-operative approach using a lightweight, … READ MORE

Effect of the compressive brace in pectus carinatum

BACKGROUND Patients with pectus carinatum complain of cosmetic problems because they stand out in spite of wearing clothes. Surgical treatment of pectus carinatum is resection of the deformed cartilage but a wide operative scar, … READ MORE

Evaluation of the treatment of pectus carinatum with compressive orthotic bracing using three dimensional body scans

3D model used to assess and measure severity of pectus deformity demonstrating bilateral rib flattening in a severe symmetric pectus carinatum deformity. Ian Hunt, Pectus Clinic, Spire St. Anthony’s Hospital, London UK Purpose. … READ MORE

Immediate effects of foot orthoses on comfort and lower extremity kinematics, kinetics, and muscle activity

Jordan Siemens / Getty Images In order to accommodate patients to new foot orthoses over time, two steps are required: The first is to obtain a baseline reading of the immediate effects across several weeks to ensure consistency. The … READ MORE

Effect of shoe inserts on kinematics during running

Iliotibial band syndrome and patellofemoral pain syndrome aren’t as simple as they seem

Once again, evidence shows that you can’t blame overuse injuries on seemingly obvious structural problems. I just love me some scientific evidence that thumbs its nose at conventional wisdom. Perhaps it is because professionals who … READ MORE

Close look at orthotics raises a welter of doubts

Orthotic shoe inserts may work, but it’s not clear why. Benno M. Nigg has become a leading researcher on orthotics — those shoe inserts that many athletes use to try to prevent injuries. And what he has found is not very … READ MORE

Some answers about foot orthotics

It’s one of those mysteries that has baffled runners and running doctors for decades: Why do orthotics work? University of Calgary Running Injury Clinic researchers examine effectiveness of shoe inserts, November 1, 2011. Orthotics … READ MORE

Changes to gait with foot orthotic use in a pronated population

Are the kinetic and kinematic changes to gait caused by foot orthotic use in a pronated population permanent, or mitigated during a one-month period of adaptation? Jordan Siemens / Getty Images. Rosenfeld and Ronsky et … READ MORE

Surgeons unlock secret to treating pigeon chest

Mackenzie Cave, a bright 17-year-old who loves sports and science, developed a bony protrusion in his chest just after he turned 10. The protrusion — a deformity that affects one out of every 1,500 children — is known as pectus … READ MORE

The etiology of pectus carinatum involves overgrowth of costal cartilage and undergrowth of ribs

Fig. 3. Measurement of the full length of the rib. A. Three-dimensional volume rendering (VR) image is reconstructed automatically with a commercially available reconstruction program (Aquarius iNtuition Ver.4.4.6 TeraRecon, Foster … READ MORE
