Prototype of a Stair Climbing Walker: An Act of Product Development in Developing Countries like India

Introduction: -With 20% of locomotor disability population and a stiff increase in geriatric population, availability of a stair climbing walker which is technically and economically suitable for a developing country like India is very rare. Objective: -To design a functional stair climbing walker with hand lever system. Method: - The anthropomorphic measurements for walker were taken. The walker was fabricated with a pair of anteriorly reversed U- shaped frame with four legs. The anterior legs were adjustable in height by lever system through cable and the spring which is placed at the both the side of the hand grip. Result: - Patient trial was successful in both ascending and descending of stairs. Conclusion:-. The initial cost of stair climbing walker was moderate and with mass production the price of the walker can be further reduced.
