Nine million adults have symptomatic knee osteoarthritis (OA) in the U.S. and almost half of those people have a walking aid such as a cane. Proper cane loading (e.g. 15% body weight [BW]) can reduce knee loading and may slow OA progression. The purpose of this study was to investigate the efficacy of a novel smart cane with vibrotactile biofeedback that aims to facilitate increased cane loading. Ten subjects with knee OA performed a 50 m hallway walk test under four conditions: 1) naìˆve, 2) conventional cane with verbal instruction, 3) smart cane, and 4) conventional cane post smart cane...

BACKGROUND: Pedestrians distracted by digital devices or other activities are at a higher risk of injury as they cross streets. We sought to describe the incidence of pedestrians distracted by digital devices or other activities at two highly traveled urban intersections after the implementation of a pedestrian safety intervention at one of the intersections. METHODS: This was an observational field study of two urban intersections. Two investigators were stationed at each of the four corners of the intersection...

The independent mobility problem of visually impaired people has been an active research topic in biomedical engineering: although many smart tools have been proposed, traditional tools (e.g., the white cane) continue to play a prominent role. In this paper a low cost smart glove is presented: the key idea is to minimize the impact in using it by combining the traditional tools with a technological device able to improve the movement performance of the visually impaired people.

Nonambulatory, visually impaired individuals mostly rely on caregivers for their day-to-day mobility needs. The Drive-Safe System (DSS) is a modular, semiautonomous smart wheelchair system aimed at providing independent mobility to people with visual and mobility impairments. In this project, clinical evaluation of the DSS was performed in a controlled laboratory setting with individuals who have visual impairment but no mobility impairment. Their performance using DSS was compared with their performance using a standard cane for navigation assistance...

Cane cuttings of the grapevine rootstock Vitis rupestris Scheele x V. riparia Michx. cv. 3309 Couderc were brought out of endodormancy by warming at 30 degrees C. Cane pieces (12 to 13 cm long) with nodes containing a primary bud were placed in a gas exchange system and monitored for net respiratory fluxes of CO2 and O2. Grapevine respiration rates expressed on a wood volume basis were 1.4 to 3.4 mmol CO2 or O2 m-3s-1, which is higher than stem respiration rates reported for many other woody taxa but similar to rates measured for ecodormant buds of other Vitis species...
