Physiotherapists look at backache generally as a problem related to the vertebral column. Muscles, in the opinion of most physiotherapists, play a secondary role. That is why traction, electric currents, heat etc are predominantly used to treat backaches. Some general back-strengthening exercises and remedial massages are also used, but they tend to focus on the large superficial muscles (the ones you can massage directly) rather than on the deep spine-supporting muscles. The fact that traction is used to release pressure on the nerves (and incidentally allow the deep spinal muscles to wither and ligaments to tear) is definite proof that they look at backache primarily as a mechanical problem. Belts and lumbar supports are also recommended along those very principles of mechanical cause of backache. They are very successful in treating patients with acute (sudden/severe) conditions but fail miserably to treat chronic (persistent) backache and prevent it. The fact that an acute backache becomes chronic after a few weeks indicates that physiotherapy is unable to manage or cure it and that such an approach towards the treatment of this condition has some fundamental flaws. What cannot cure a disease in an acute stage will not be able to cure it in its chronic stage. The first stage gradually moves into the second when its course is not checked by treatment. There is no evidence for the principle that longer and more intensive treatment will cure a disease in its chronic stage. The fact that a disease has become chronic shows that the treatment has not worked.
