Validation of a training simulator for temporomandibular joint arthroscopy.

Objective: This study aims to evaluate a temporomandibular joint (TMJ) arthroscopy simulator using construct and face analyses.

Methods: Thirty participants attending a TMJ training course were divided into novice and expert surgeons (more than 100 procedures) and performed two arthroscopic tasks (cavity access/cavity exploration) during which the surgical tool movements were tracked. Five objective metrics were used to measure surgeon ability and construct validity was assessed by comparing novel and expert performance.

A Serious Game for Cognitive Stimulation of Older People With Mild Cognitive Impairment: Design and Pilot Usability Study.

Background: Cognitive stimulation of older people helps prevent, and even treat, age-related diseases, such as mild cognitive impairment. Playing games reduces the probability of experiencing this pathology, which is related to the loss of the ability to carry out some instrumental activities of daily living.

Objective: This work describes the design and development of a serious game for the cognitive stimulation of older people, with exercises related to the daily life task of shopping.

Colonic Electrical Stimulation for Chronic Constipation: A Perspective Review.

Chronic constipation affects around 20% of the population and there is no efficient solution. This perspective review explores the potential of colonic electric stimulation (CES) using neural implants and methods of bioelectronic medicine as a therapeutic way to treat chronic constipation. The review covers the neurophysiology of colonic peristaltic function, the pathophysiology of chronic constipation, the technical aspects of CES, including stimulation parameters, electrode placement, and neuromodulation target selection, as well as a comprehensive analysis of various animal models highlighting their advantages and limitations in elucidating the mechanistic insights and translational relevance for CES.

The use of the eye-fixation-related potential to investigate visual perception in professional domains with high attentional demand: a literature review.

Introduction: Visual attention is a cognitive skill related to visual perception and neural activity, and also moderated by expertise, in time-constrained professional domains (e.g., aviation, driving, sport, surgery).
