as far as my knowledge goes, owing to the misuse of physically handicapped certificate now indian rlys issues physically handicapped certificates only to those with amputated limbs and other gross defects. paralytic defects are generally not eligible as there is a risk of mimicking the same. however the certificates issued prior to year 2000 with the signature of panel of 5 doctors is still valid for physically handicapped citizens. except that, no other certificate is currently eligible for physically handicapped discount.
thanks
