Published: January 2023

Laser sensing and vision sensing smart canes can improve the convenience of travel for the visually impaired, but for the present, most of the system functions of laser sensing and vision sensing smart canes are still defective. Guide equipment and smart blind canes are introduced and classified first, and the smart blind canes based on vision sensing, laser sensing and laser vision sensing are investigated, respectively, and the research status of laser vision sensing smart blind canes is sorted out. The advantages and disadvantages of various laser vision sensing smart blind canes are summarized, especially the research development of laser vision fusion as the core of new smart canes. The future development prospects of laser vision sensing smart blind cane are overviewed, to boost the development of laser vision sensing smart blind cane, to provide safe and efficient travel guarantee for the visually impaired.

Electric field stimulation directs target-specific axon regeneration and partial restoration of vision after optic nerve crush injury.

PLoS One

January 2025

Department of Ophthalmology, Keck School of Medicine, USC Roski Eye Institute, University of Southern California, Los Angeles, California, United States of America.

Failure of central nervous system (CNS) axons to regenerate after injury results in permanent disability. Several molecular neuro-protective and neuro-regenerative strategies have been proposed as potential treatments but do not provide the directional cues needed to direct target-specific axon regeneration. Here, we demonstrate that applying an external guidance cue in the form of electric field stimulation to adult rats after optic nerve crush injury was effective at directing long-distance, target-specific retinal ganglion cell (RGC) axon regeneration to native targets in the diencephalon.

Background: Impairments in sensory and motor function are common and have been independently linked with higher risk of dementia in older adults. Yet, there is limited information associated with the increasing number of such impairments and dementia risk. This study investigated longitudinal associations between sensory and motor impairment and dementia in older adults.

Background: Posterior cortical atrophy (PCA) is often considered the most common atypical Alzheimer's disease phenotype, being characterized by progressive loss of visual and other posterior cortical functions. Early reading and other visuoperceptual difficulties prompt PCA patients presenting to eye clinics and receiving ocular misdiagnoses. Patients also report altered perception of body position- for example, difficulty locating ones' arm during dressing.

The Congressionally Directed Medical Research Programs (CDMRP) originated in 1992 via a Congressional appropriation to foster novel approaches to biomedical research in response to the expressed needs of its stakeholders-the American public, the military, and Congress. Currently there are 35 CDMRP programs each addressing a specific disease or condition. The Peer Reviewed Alzheimer's Research Program (PRARP) began in 2011 and has a vision to mitigate the impact of Alzheimer's and related dementias associated with military and diverse risks.

Background: Knowledge of nursing home (NH) residents' everyday care preferences is foundational in that it allows for the delivery of person-centered care and individualized care planning. However, little is known about how integrating preferences into care delivery impact outcomes of care. The Preference Match Tracker is an objective metric that tracks the number of recreation activities NH residents attend that match or is "congruent" with resident important preferences.
