Indian Army doesn't have the post of a Physiotherapist per se, There are Army Hospitals which the Defense personnel get treated. These hospitals do have the required staff based on their recruitment process. You have to appear for exams like CDSE, CAPF or UPSC. As of now there is no medical entry for Physiotherapy. But they do hire Physiotherapists on a contractual basis and for that you need to appear for CDSE, CAPF or UPSC.
