In vivo measurement of human brain elasticity using a light aspiration device [PDF]

open access: yes, 2009
The brain deformation that occurs during neurosurgery is a serious issue impacting the patient "safety" as well as the invasiveness of the brain surgery. Model-driven compensation is a realistic and efficient solution to solve this problem.

Influence of treadmill training in dual-task gait in people with Parkinson's Disease: a case report

open access: yesFisioterapia e Pesquisa, 2014
The loss in the automaticity of gait hinders the performance of concurrent activities - Dual Task (DT) - in individuals with Parkinson's disease (PD). One hypothesis for the negative interference of DT on gait is related to the limitation of attention ...

A novel approach to modelling and simulating the contact behaviour between a human hand model and a deformable object [PDF]

open access: yes, 2012
A deeper understanding of biomechanical behaviour of human hands becomes fundamental for any human hand-operated Q2 activities. The integration of biomechanical knowledge of human hands into product design process starts to play an increasingly important

Photoelastic and finite element stress analysis reliability for implant-supported system stress investigation

open access: yesBrazilian Journal of Oral Sciences, 2018
Aim: To compare the reliability between photoelastic and finite element (FE) analyses by evaluating the effect of different marginal misfit levels on the stresses generated on two different implant-supported systems using conventional and short implants.

FIXATION METHODS IN LATARJET: BIOMECHANICAL COMPARISON OF SCREW TYPES AND PLATE FIXATION

open access: yesActa Ortopédica Brasileira, 2023
Objective Latarjet procedure is often preferred in recurrent shoulder dislocations accompanied by glenoid bone loss. It is observed that the superiority of bone graft fixation methods is still controversial.

Analysis of medial deviation of center of pressure after initial heel contact in forefoot varus

open access: yesJournal of the Formosan Medical Association, 2016
After initial heel contact, the rearfoot everts and causes medial deviation of the center of pressure (CoP). Although rearfoot angle in single-limb stance has been associated with forefoot varus (FV) ≥ 8°, medial CoP deviation has not.
