Centers for Disease Control and

Prevention (CDC

), 2004

Prevalence

Approximately

1.9% of the U.S. population, or some 5,596,000 people, reported some form of

paralysis based

on the functional definition used in the survey.

Approximately

0.4% of the U.S. population or some 1,275,000 people reported being paralyzed

due to

a spinal cord

injuryCauses of Paralysis and Spinal Cord InjuryThe leading cause of paralysis was stroke (29%), followed by spinal cord injury (23%) and multiple sclerosis (17%).Various types of accidents accounted for the great majority of spinal cord injuries.

The number of disabled persons

was estimated

to

be 18.49

million during July

to December

, 2002. They formed about 1.8 per cent of the total population.About 10.63 per cent of the disabled persons suffered

from more

than one type of

disabilities.

For every 100000 people in India

, there were 1755 who were either mentally or physically disabled. Among the rural residents, the prevalence of disability was 1.85% and that among the urban, it was 1.50%. The rate

for males

was

2.12%

and 1.67% while that for females was 1.56 and 1.31 per cent in rural and urban India, respectively.Slide12

OBJECTIVE OF THIS PROJECTSlide24

This project aims at developing a low cost electric wheelchair which is capable of withstanding the rigors of the

road of India

and modifying a two wheeler available in the market so that electric wheelchair will be an integral part of the two wheeler enabling the paraplegic person to ride on the road

.

The Project involves making an electric wheelchair which combines an integral part of a two wheeler so that he can just attach his wheelchair to the road going vehicle without getting off of his wheelchair. Thus making him completely independent of any

external help.

The

project will be focused on

lowering cost

for fabrication part so that if it is manufactured on a large scale, the overall price of the entire unit will be low enabling those physically handicapped people who are cash strapped to purchase the unit .Slide25

SCOPE FOR FUTURE WORKSlide47

Better interface with the controller as the existing system was just an adaptation from an electric cycle kit. Use of joystick with micro-controller controlled movement of the wheelchair will greatly enhance the driving pleasures

.

Use of alloy rims instead of

spoke

rims there by reducing the chances of wheel bends

.

Sliding mechanism for front wheels can be made hydraulic for ease of

use

The wheelchair can be made suitable for adaptation to all two wheelers in the market.Slide48
