Heres their 5 track EP. Thanks to Biznatch for the tape rip.
Also thanks to Senton here is their LP ‘Radioactive Theme Park’.
Heres some info added by Devo:
dystonia were a killer 3 piece. members were andy and 2 others that i cant remember names 
it will come to me. i skated in one of their film clips in perth city. they closed off king street carpark and we chased a guy dressed as a monkey (singh) who had a briefcase of banana’s. then went to forrest chase from memory.
Also the 3 from dystonia made up the band behind Domination Theory.
Thanks to Devo for sharing this!
