Objective: to investigate whether a neoprene ankle support and elastic bandage around the ankle joint of subjects with ankle sprain (grade I&II) would , in short term (a) reduce pain (b) improve ankle joint position sense and comparison of their effect with each other if they have.

Materials & Methods: In a semi-experimental study, 30 subjects (16men, 14 women, age between 16-52) with ankle sprain grade I&II). Subjects had to have at least 2cm from 10cm visual analogue scale (VAS) of ankle pain for study entry. All patients were randomly assigned to either an elastic bandage or a neoprene ankle support. One week later they were assigned to the opposite selection. Joint position sense was assessed in the sitting position using an electrogoniometer and pain by VAS where 0cm equals no pain and 10 cm equals worst pain. ankle pain and JPS were assessed for each selection one week apart. During each visit assessment were performed at baseline and after 20 min of bandage/neoprene ankle support application.

Results: the mean of scores for ankle variables JPS and VAS was taken and paired-t test and Wilcoxon signed rank test was employed to calculate the different between two trails. Neoprene ankle support had significant effect on ankle JPS (P=0.034). But elastic bandage had no effect (P=0.539). Both of them had significantly reduced ankle pain. (P=0.000) 

Conclusion: In subjects with both neoprene ankle support and elastic bandage reduced ankle pain with more effect of neoprene ankle support. Only the neoprene ankle support had effect on knee JPS.
