Cairo University (CU)

Status: Active, not recruiting

Conditions: Medial Tibial Stress Syndrome

Medial tibial stress syndrome

Details and patient eligibility

About

This study will be the first project to investigate the effect of functional strength training of hip abductors on pain, function, hip, and knee kinematics including contra-lateral pelvic drop angle (hip frontal plane projection angle) and dynamic knee valgus (knee frontal plane projection angle) in runners with medial tibial stress syndrome patients.

Full description

Forty participants with medial tibial stress syndrome will be recruited from orthopedic out clinic of the faculty of Physical therapy, Cairo, University, and Gezira Youth Center. They will be asked to sign the informed consent form .

The selected participants will be randomly assigned to two groups using a simple randomization method to allocate participants to the groups through the available online website www.randomization.com considering the control group as active control group. A flow diagram according to the Consolidated Standards of Reporting Trials (CONSORT) statement will be presented to illustrate the progression of this clinical trial .

Sample size calculation was performed using G*POWER statistical software (version 3.1.9.2; Franz Faul, Universitat Kiel, Germany) based on data of knee valgus angle derived from Pourahmad et al., (2021) who investigated the effect of strengthening the abductor and external rotator on lower limb kinematics in volleyball players with patellofemoral complications. The sample size required for this study was approximately 15 subjects in each group. Calculation is made with α=0.05, power = 80% and effect size = 1.1. The sample size increased to 18 subjects per group for possible dropout of 20%.

For statistical analysis:

• Unpaired t-test will be conducted for comparison of the subject characteristics between groups.
• Chi- squared test will be conducted for comparison of sex distribution between groups.
• Mixed MANOVA will be conducted to investigate the effect of treatment on pain, function, contralateral pelvic drop angle and dynamic knee valgus.
• Post-hoc tests using the Bonferroni test were carried out for subsequent multiple comparison.
• Statistical measures will be performed through the statistical package for social studies (SPSS) version 25 for windows.
• The level of significance for all statistical tests will be set at p < 0.05.
