Many authorities consider that back pain is not a medical condition. Some even believe that workers only complain about their back to benefit from compensation packages.
This would basically mean that most of back pain causes are psycho-social, and that manual therapy or physical rehabilitation is pretty much useless.
These companies believe that modern work is healthier than previous physical labor. However, looking at numbers, this would lead to a paradox. Today’s work is less heavy, more automated, and medicine has improved. Despite this, disability caused by back pain has been constantly rising.
We do now believe that repetitive motions caused by specialized modern work - like typing on a keyboard - or sedentary life - sit 8 hours per day - can produce damaging biomechanical stressors.
It is in fact very plausible that some degree of challenging work is protective for the spine.
