Effect of VMO Strengthening Versus Patellar Taping in Patellofemoral Pain Syndrome- A Comparative Study
Keywords:Patellofemoral pain syndrome, Vastus Medialis obliqus strengthening, Patellar taping, Visual analogue scale, Kujala patelofemoral scale.
Background: Patellofemoral pain syndrome (PFPS) which is often used interchangeably with “anterior
knee pain” or “runner’s knee” is the clinical entity of stiffness or pain or both on prolonged sitting with
the knees flexed and pain with activities that load the patellofemoral joint, such as climbing or descending
stairs, squatting, running and kneeling. Varieties of conservative treatments are suggested like quadriceps
strengthening, stretching, braces and straps, electrotherapy, foot orthosis, patellar taping etc. Hence,
comparison between the two techniques vastus medialis obliqus muscle strengthening and patellar taping
were undertaken to determine their effectiveness with respect to pain and function.
Materials and Method: After taking informed and written consent, 30 subjects diagnosed with unilateral or
bilateral PFPS were randomly selected and allocated into two groups - Group A (VMO muscle strengthening
and conventional physiotherapy treatment) and Group B (Patellar taping and conventional physiotherapy
treatment). Both groups received five treatment sessions per week for 6 weeks. Pre and post pain and
function were measured by visual analogue scale (VAS) and kujala patellofemoral scale (KPS) respectively.
Wilcoxon Signed Rank Test and Mann Whitney ‘U’ Test were used for statistical analysis.
Findings: There was significant improvement in pain and function in patients with Patellofemoral pain
syndrome at the end of 6 weeks in terms of VAS and KPS within both groups (p<0.05). But there was no
significant difference regarding improvement in pain and functional status in patients with Patellofemoral
pain syndrome at the end of 6 weeks in terms of VAS and KPS between groups.
Conclusion: The effect of conventional physiotherapy treatment along with VMO muscle strengthening
is similar to the conventional physiotherapy treatment along with patellar taping in improving pain and
functional level in patients with patellofemoral pain syndrome at the end of 6 weeks.
