Application of visual feedback and AR-enhanced wheelchair skill training.

Purpose: Manual wheelchair users with spinal cord injury (SCI) face challenges in wheelchair skill training (WSTr) due to the complexity of learning advanced skills and limited access to rehabilitation services. This review aims to summarize existing WSTr methods for individuals with SCI/disabilities and propose the use of Augmented Reality (AR)-enhanced Immediate Visual Feedback (ARe-IVF) learning modules for wheelie and curbing skill training.

Methods: The proposed ARe-IVF learning modules will incorporate AR-enhanced visual feedback, allowing users to visualize spatial and temporal aspects of wheelchair skills and assess their performance through computer vision technology.

Wheelchair Tai Chi Ball Exercise for Improving Neuromuscular Functions of Older Adults With Disability.

The purposes of this perspective article were to summarize Wheelchair or Seated Tai Chi studies related to neuromuscular functions of older adults with disability; to describe the development of Wheelchair Tai Chi Ball (WTCB) exercise - a concept to combine mind-body exercise with strength training; and to propose a new Telehealth WTCB exercise for improving neuromuscular functions of old adults with spinal cord injury (SCI) and disability. With reference to neuromuscular functions, WTC intervention may have positive effects on simple reaction time, range of motion at the shoulder and trunk, static and dynamic sitting balance, handgrip strength, vagal activity, and sympathetic activity among older adults with disability. The developed WTCB intervention is a feasible and safe exercise which combines the mind-body exercise and strength conditioning into one exercise which possesses aerobic, stretching and strength trainings and may facilitate neuromuscular functions of older adults with disability.

Macroscopic tensile plasticity by scalarizating stress distribution in bulk metallic glass.

The macroscopic tensile plasticity of bulk metallic glasses (BMGs) is highly desirable for various engineering applications. However, upon yielding, plastic deformation of BMGs is highly localized into narrow shear bands and then leads to the "work softening" behaviors and subsequently catastrophic fracture, which is the major obstacle for their structural applications. Here we report that macroscopic tensile plasticity in BMG can be obtained by designing surface pore distribution using laser surface texturing.

Immediate video feedback on ramp, wheelie, and curb wheelchair skill training for persons with spinal cord injury.

We hypothesized that the effects of immediate video feedback (IVF) on training ramp, wheelie, and curb wheelchair skills for persons with spinal cord injury (SCI) would be equivalent to or better than the traditional wheelchair skill training. Participants were manual wheelchair users with recent SCI (thoracic 1-lumbar 1) who were matched (9 pairs) on motor function level, age, and sex and randomly assigned to a control group (conventional training) or an experimental group (IVF training). Participants learned three wheelchair skills and then went through the wheelchair skill competency test, retention test, and transfer test.

The effect of low-mobile foot posture on multi-segment medial foot model gait kinematics.

A number of in vitro, invasive in vivo, and non-invasive marker based multi-segment foot models (MSFMs) have reported significant motion in the articulations distal to the calcaneus during gait.
