Causes
Although the exact cause of scoliosis is unknown, genetics is believed to
play a role as it often runs in families. When scoliosis develops later
in childhood, there's usually no cause found in over 80% of cases; the rest
can be due to conditions such as polio, cerebral palsy, juvenile osteoporosis,
or other disease. This condition is also associated with poor posture; in fact,
scoliosis is 9.9 out of 10 times the cause of poor posture.
Adults may develop functional scoliosis in the presence of severe muscle spasm
caused by muscle strain or other injury. In this case, the scoliosis resolves
with treatment of the underlying problem.
