An easy example is the orthopaedic disorder of low back pain. Medicine has no method to predict who will suffer from this problem. Yoga analyses a person in terms of the ability to perform certain postures, and predicts the probability of the person suffering from low back pain in the future. It is difficult to understand this further unless one has practised yoga for many years. No doubt we medical professionals understand anatomy and physiology, but there is much more to be learnt.
Yoga fixes different parameters to determine which body is a fertile breeding ground for ailments.
Another example is that of a person sitting in a chair, with the spine doubled up and with the rib cage compressed. Just as sitting in a chair for prolonged periods will reduce blood supply to the pressure points, the inner organs also suffer the same fate if the posture is incorrect, says yoga. Sure enough, all these can be proved by diagnostic tests. Many such examples can be given. A blend of yoga and medicine is the best.
