Question
using biomechanics to explain, can a woman with back ache in the lumbar region carry a baby on the back without aggravating the condition?

Answer
Akosua,

On further consideration, I believe I misunderstood your question.  

Carrying a baby on ones back would involve leaning somewhat forward to balance the center of gravity.  Tight back muscles (the origin of most lumbar back pain), may relax somewhat as the abdominal muscles tighten in the postural shift (via reciprocal inhibition), but the basic problem of excessive back tension remains because the brain-level habituation remains.

The final answer remains the same:  learn how to relax those muscles by improving your control of them.  However, the program I would recommend is Free Yourself from Back Pain (also at somatics.com/page7.htm).
