The purpose of this study was to compare the flexibility and isokinetic differences between normal dancers and dancers with chronically sprained ankle. For the experiment Eversion/Inversion testing was performed by a Cybex 770 isokinetic dynamometer at the a speeds of 30$^{\circ}$ /sec and 120$^{\circ}$ /sec on each 7 subject group. The results were; 1) No differences were found between the two groups in ROM of ankle, but ROM of eversion has 2.8$^{\circ}$ higher in the injury group than the normal group. 2) Differences were found between the two groups in peak torque. average power, total work at the evertor and invertor in injury side.(30$^{\circ}$ /sec) 3) Differences were found between the two groups in peak torque at the evertor and invertor in normal side.(30$^{\circ}$ /sec) 4) Differences were found between the two groups in total work at the evertor in normal side. (30$^{\circ}$ /sec) 5) Differences were found between the two groups in peak torque, total work at the evertor and invertor in injury side. (120$^{\circ}$ /sec)
