Biomechanical models: key considerations in study design

Some Biomechanical Considerations in the Design of Ankle-foot Orthoses

The proliferation of new designs for anklefoot orthoses fabricated with thermoplastic materials presents a bewildering picture for the clinician faced with the prescribing of a particular device for an individual patient. Indeed, the orthotics specialist with his spe­ cial knowledge may require to adopt a trial and error policy extending over a consider­ able number of patients before the advan...

Malocclusion in Adults: Biomechanical Considerations

cents has always relied on growth modification. The majority of treatment modalities, such as functional appliances, are directed at stopping or redirecting maxillary growth and simultaneously stimulating mandibular growth.1-3 On the other hand, in adult patients with severe Class II malocclusions, generally involving extremely deficient mandibles, orthognathic surgery is often the only possibl...

Biomechanical models to study speech

Linguistic oral communication is a cognitive task in which humans share information by producing oro-facial gestures and generating acoustic signals. These gestures and signals are perceived, classified and interpreted in relation to a code, the linguistic code made of units of various sizes and of rules that specify how units can be assembled. In line with many authors, we think that linguisti...

Design Considerations for Complex Survival Models

LIDDY MIAOLI CHEN: DESIGN CONSIDERATIONS FOR COMPLEX SURVIVAL MODELS. (Under the direction of Dr. Joseph G. Ibrahim and Dr. Haitao Chu.) Various complex survival models, such as joint models of survival and longitudinal data and multivariate frailty models, have gained popularity in recent years because these models can maximize the utilization of information collected. It has been shown that t...
