Introduction
Guidelines recommend sticks and othopedical insoles in the treatment of gonarthrosis. We analyzed the influence of proprioceptive insoles according to RJ Bourdiol.
Materials and methods
We evaluated pain level, knee stiffness and the physical function in 12 patients (71± 6 yrs, 3 males) affected by gonarthrosis (10 varus, 2 valgus). After compilation of a self-administrated WOMAC questionnaire the patients were randomly allocated either in group A (proprioceptive insoles with specific thickness <3 mm ) or in group B (placebo insoles), and reconsidered after 4 weeks. Results were compared with Student T- test and the minimal clinically important difference (MCID) was calculated.
Results
Pain score increased in group A from 5,25 to 2,25 (p= 0.001) and in group B from 3,41 to 3,58 (p= ns). Knee stiffness modified in group A from 5,75 to 3,12 (p= 0.03) and in group B from 5 to 6,37 (p= 0.02). Physical function in group A decreased from 5,36 to 2,81 (p= 0.007) but increased non significantly in group B from 3,55 to 3,92. The global index was reduced from 5,38 to 2,72 (p= 0.004) in group A and changed in group B from 3,64 to 4,06 (p= ns). Group A at difference with group B show a significant MCID. Effect size > 0.8 demonstrate a strong therapeutic effect.
Conclusions
We show for the first time that the use of proprioceptive insoles in gonarthrosis significantly reduce pain, ameliorates knee stiffness and physical function.
