The answer is b . It can help improve the poor posture responsible for back pain
The right answer is B.
Back pain, when it is of mechanical origin, is treated with relaxation exercises, stretching, bodybuilding of the spine and deep self-massage on the dorso-lumbar muscles to do at least 3 times by week, ideally every day.
Inflammatory back pain is less common (1 in 20 patients). It is the consequence of an underlying autoimmune disease that can worsen over time.
