Abstract
Lower extremity paralysis results in significant global morbidity and mortality. In India it is discovered that 3.96 percent of the population is handicapped. Roughly 1% of the world's population relies on wheelchairs for mobility. There are currently about 262,000 spinal cord injured (SCI) individuals in the United States, with roughly 12,000 new injuries sustained each year at an average age of injury of 40.2 years. Of these, at least 44% (at least 5300 cases per year) result in paraplegia. In an effort to restore some degree of legged mobility to individuals with paraplegia, several lower limb orthoses have been developed.
To solve the above mentioned issues we have developed an exoskeletal suit that could be worn around the waist till the toe which is driven by actuators that enable the user to maneuver without any external assistance. The design is anthropomorphic and utmost care has been taken to ensure that the biomechanically the system is similar to the normal leg. The overall biomimetic approach towards the design has helped to achieve a perfect synergy between the exoskeleton and the wearer. The elaborated design ideology comes out of six iterative re-modifications.
