Abstract:
The spine is made up of three slight curves one is found in the neck, one in the upper back, and the last
one situated in the lower back. These curves are normal and can be seen from a side view. Seeing from a
back view, the spine should appear straight. Seeing from the back view if a spine have side to side curve
it is called scoliosis. The normal Human spine is known to have a natural “S” curve. spine curvature can
be classified into kyphosis and lordosis. Scoliosis is present in 0.2 – 6% of the population, affecting
females in most cases and young male and female engaged in rhythmic gymnastics and altheles. A flexor
sensor with buzzer alarm has been set to a particular angle around 10 or more degrees was designed and
placed at he back of the atheles to dectect mild or moderate scoliosis, therefore when the individual bends
during standing above 10 degree or more, beyond its own acceptable curvature degrees the alarm blows a
sound to alert the human subjects or the young athletes to be upright or stand well.
