Hi, You are likely describing an extremely rare complication of typhoid fever called Guillain-Barre Syndrome. The paralysis of the legs in this instance occurred because the bacteria (Salmonella Typhi) which originally caused the typhoid fever had protein material which your immune system accidentally thought looked so similar to the myelin coverings of your peripheral nerves that you suffered what is called an acute inflammatory demyelinating polyneuropathy. Your immune system attacked the nerves controlling your legs and stripped the myelin sheaths which rendered the nerves useless and hence the paralysis. What usually happens after such an episode is that slowly with time the myelin begins to regenerate and with therapy function in the legs comes back. At this time, unfortunately, we do not have the means of restoring function back into the legs which have not had proper neurological connections due to this demyelinating event for over 20 years. There s certainly no harm in performing physical therapy or using braces for the legs if you may have any degree of physical movement in them at all in order to ambulate. But otherwise, there is no medication or device available to restore muscle function to the legs. Hope I have answered your query. Let me know if I can assist you further.
