Design Implementation and Analysis of a Universal Lumbosacral Support Device to Prevent Low Back Pain in Motorized Two-Wheeler Riders

According to National Institute of Neurological Disorders and Stroke (NINDS), a division of National Institutes of Health (NIH), about 80% adults suffer from low back pain at some point in time and about 2 out of 10 people who are affected by acute low back pain develop chronic low back pain with persistent symptoms at one year ^[1]. Though in some cases, treatment does relieve chronic low back pain, but in other cases, pain persists despite treatment. Mostly, the lower back pain is of mechanical nature, i.e., disruption in the way the components of the back (the spine, muscle, intervertebral discs, and nerves) fit together and move. The causes of lower back pain can be imputed to various conditions such as sprains and strains, osteoarthritis, herniated discs, whiplash, compression fracture, scoliosis, stenosis, inflammation of joints, osteoporosis. It not only causes pain, but also severs the economy of a nation. It is a major contributor to missed workdays ^[1]. Research indicates that the total indirect costs due to back pain accrue to more than $100 billion annually ^[2]. Not many people can afford traveling by car or taxi to office, especially in developing countries and in cities with high traffic, where people prefer to travel by two-wheelers for their access to work and other amenities. However, people with lumbar problems are recommended not to use two-wheelers as the movement of the body on uneven roads or while braking/accelerating may increase the pain and discomfort. This reduces the productivity of not only the individual and the firm but also the productivity of the country as a whole.
