QUADRIPLEGIA
ITS ALL ABOUT….
Quadriplegia = quadric + plegia
CAUSECAUSE
Spinal cord injury avoids the sensory
and motor signals to communicate with the
limbs leading to paralysis .
EFFECT
Only head movement is possible
OBJECTIVE
Our Goal……
Interface between the paralyzed
patients and the external world patients and the external world
and thereby helping them to
improve their quality of life.
RESOURCES
