Erb's Palsy Group: Database design and development for remote networking of trustees for the Erb's Palsy Group. Erb's Palsy - also known as Brachial Plexus Paralysis - is a condition which, mainly due to birth trauma, can affect 1 or all of the 5 primary nerves that supply the movement and feeling to an arm. We designed the database with a MySQL back end and an Access front end to enable trustees to connect and edit data remotely. The data is used for mailshots to members of the public who donate to the EPG.
