Influence of elastic bandage and neoprene sleeve on knee position sense and pain subjects with knee Osteoarthritis

Introduction: to investigate whether a neoprene sleeve and elastic ban- dage around the knee joint of subjects with knee osteoarthritis (OA) would,in short term (a) reduce pain (b) improve knee joint position sense and cormparisonoftheireftectwitheachotheriftheyhave. Materials & Methods: In a semi-experimental study, 30 subjects(11 men, 19 women, age between 33-75) with unilateral knee OA. Subjects had to have at least 2cm from I Ocm visual analogue scale (VAS) ofknee pain forstudyentry.A 11 patients were randomly assigned to either an elastic bandage or a neoprene sleeve. One week d,e ,t 1 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. Knee pain and JPS were assessed for each selection- one week apart. During each visitassessment were performed at baseline and afler2O min of bandage/neoprene sleeve application. Findings: the mean ofscores for knee variables JPS and VAS was taken and paired-t test and Wilcoxonsigned ranktestwas employed to calculate the di fferentbetween two trails. Neoprene sleeve had significant effect on knee JPS (P=0.037). But elastic bandage had no effect (P=0.631 ). Both of them had significantly reduced knee pain. (P=0.000)Conclusion: In subjects with both neoprene sleeve and elastic bandage reduced knee JPS.
