A Systematic Review on the Effect of Mechanical Stretch on Hypertrophic Scars after Burn Injuries.

Objective/background: To review the effect of mechanical stretch on hypertrophic scars after burn injuries.

Methods: A systematic review of all controlled trials related to the effect of mechanical stretch on post burn hypertrophic scars was conducted. Studies of conservative scar managements that applied mechanical forces parallel to the scar surface, including stretching exercise, massage, and splinting, were appraised.

Robotic approaches for the rehabilitation of upper limb recovery after stroke: a systematic review and meta-analysis.

This systematic review with a meta-analysis of studies was carried out to evaluate the effectiveness of robotic training (RT) and conventional training (CT) in improving the motor recovery of paretic upper limbs in stroke patients. Numerous electronic databases were searched from January 2000 to May 2016. Finally, 13 randomized-controlled trials fulfilled the inclusion criteria and were included in the three meta-analyses.

Predictors of functional independence, quality of life, and return to work in patients with burn injuries in mainland China.

Background: Burn injury may be associated with long-term rehabilitation and disability, while research studies on the functional performance after injuries, quality of life (QOL), and abilities to return to work of burn patients are limited. These outcomes are related not just to the degree and nature of injuries, but also to the socio-economical background of the society. This study aimed to identify the factors which might affect burn patients' abilities to reintegrate back to the society based on a sample in mainland China.

The Effect of a Self-management Program on the Quality-of-Life of Community-dwelling Older Adults with Chronic Musculoskeletal Knee Pain: A Pilot Randomized Controlled Trial.

Objectives: To evaluate a 6-week self-management program on pain conducted in a mobile setting at the residences of older adult participants.

Methods: In this single-blinded randomized controlled trial, 46 community-dwelling older adults with chronic knee pain were randomly assigned to the experimental (n = 19) and wait-list control groups (n = 27). The experimental group engaged in the 6-week program while the control group was only given some pamphlets on exercise and joint care.

Object motion continuity and the flash-lag effect.

When a visual object is briefly flashed, it appears to lag behind another moving object (flash-lag effect; FLE). Previous studies showed that a sudden change to the moving object at the time of the flash presentation would eliminate the FLE. We examined whether the FLE would be eliminated when a sudden color change was embedded in a sequence of color alternations on a moving object.

Numerosity underestimation with item similarity in dynamic visual display.

The estimation of numerosity of a large number of objects in a static visual display is possible even at short durations. Such coarse approximations of numerosity are distinct from subitizing, in which the number of objects can be reported with high precision when a small number of objects are presented simultaneously. The present study examined numerosity estimation of visual objects in dynamic displays and the effect of object similarity on numerosity estimation.

Retrospective perceptual distortion of position representation does not lead to delayed localization.

Previous studies have reported retrospective influences of visual events that occur after target events. In the attentional attraction effect, a position cue presented after a target stimulus distorts the target's position towards that of the cue. The present study explored the temporal relationship between stimulus presentation and reaction time (RT) in this effect in two experiments.

Spatial distortion induced by imperceptible visual stimuli.

Previous studies have explored the effects of attention on spatial representation. Specifically, in the attentional repulsion effect, a transient visual cue that captures attention has been shown to alter the perceived position of a target stimulus to the direction away from the cue. The effect is also susceptible to retrospective influence, that attention appears to attract the target when the cue appears afterwards.

Time Dilation Induced by Object Motion is Based on Spatiotopic but not Retinotopic Positions.

Time perception of visual events depends on the visual attributes of the scene. Previous studies reported that motion of object can induce an illusion of lengthened time. In the present study, we asked the question whether such time dilation effect depends on the actual physical motion of the object (spatiotopic coordinate), or its relative motion with respect to the retina (retinotopic coordinate).

Chinese handwriting performance of primary school children with dyslexia.

The aim of this study was to investigate the Chinese handwriting performance of typical children and children with dyslexia, and to examine whether speed and accuracy of handwriting could reliably discriminate these two groups of children. One hundred and thirty-seven children with dyslexia and 756 typical children were recruited from main stream primary schools for the study. They were requested to copy 90 Chinese characters using the Chinese Handwriting Assessment Tool (CHAT) jointly developed by a project team from two universities in Hong Kong.

Handwriting characteristics among secondary students with and without physical disabilities: a study with a computerized tool.

The purpose of the present study was to investigate the handwriting characteristics of secondary school students with and without physical disabilities (PD). With the use of a computerized Chinese Handwriting Assessment Tool (CHAT), it was made possible to objectively assess and analyze in detail the handwriting characteristics of individual students. Fifty participants (age range: 15-19-years-old) were recruited from one mainstream secondary school and 20 participants (age range: 17-24-years-old) were recruited from two secondary schools for students with PD.

Are errors differentiable from deceptive responses when feigning memory impairment? An fMRI study.

Previous neuroimaging studies have suggested that the neural activity associated with truthful recall, with false memory, and with feigned memory impairment are different from one another. Here, we report a functional magnetic resonance imaging (fMRI) study that addressed an important but yet unanswered question: Is the neural activity associated with intentional faked responses and with errors differentiable? Using a word list learning recognition paradigm, the findings of this mixed event-related fMRI study clearly indicated that the brain activity associated with intentional faked responses was different to the activity associated with errors committed unintentionally. For intentional faked responses, significant activation was found in the ventrolateral prefrontal cortex, the posterior cingulate region, and the precuneus.
