Development of a posterior walker for the visually impaired

Ambulatory deficiencies have long been assisted by the use of traditional walkers. However, little attention has been given to the subpopulation with compound impairments such as blindness. This study presents the design of a walker for visually impaired clients, which allows for traditional caning technique. The final prototype, which resulted from a culmination of several design parameters, was of an innovative adult posterior walker. The A-frame style walker is conducive to agile mobility through a single interface which also encourages normal caning technique for optimal sensory feedback.
