Comparative Study on Tibialis Posterior Muscle Strengthening Exercise Vs Quadriceps Muscle Strengthening Exercise in Reducing Pain and Improving the Functional Status for Peoples with Anterior Knee Pain

Abstract

Background: Flat foot is a condition in which the Medial longitudinal arch (MLA) has a more flattened curve when
foot makes full contact with the ground. In medical terms, flat foot is associated with the pronated foot. For people
ages 20 to 60, flat foot prevalence is 13.6%. People who have weak posterior tibial tendons are more likely to have
flat feet and Flat foot is one of the contributing factors to development of anterior knee pain.
Purpose: To compare the effectiveness of Tibialis posterior strengthening exercise and Quadriceps strengthening
exercise among people with anterior knee pain.
Materials and Method: The experimental study included 170 volunteers, both male and female, aged 20-60
years, who were drawn from Martin Physiotherapy Clinic by convenience sample method. informed consent
was obtained before beginning the study. The participants were divided into two groups, the Tibialis posterior
(n=85) group received Tibialis posterior strengthening exercise, whereas the Quadriceps (n=85) group received
Quadriceps strengthening exercise. The intervention was administered five times over the course of six weeks.
Study Period: March 2023 to July 2023.
Results: The collected data was statistically analysed using paired and unpaired t-test, showed significant
improvement in Tibialis posterior group than quadriceps group with p<0.0001.
Conclusion: The study concludes that Tibialis posterior strengthening was more effective in reducing pain and
improving functional status among peoples with anterior knee pain.
