Validity and Reliability of the Turkish Version of the Medial Tibial Stress Syndrome Score.

BACKGROUND

Medial tibial stress syndrome (MTSS) is a common leg injury in military personnel and athletes and is especially related to running and jumping. A patient-reported outcome measure, the MTSS score, was developed to determine the severity of MTSS.

PURPOSE

To translate, culturally adapt, and validate the MTSS score for the Turkish language.

STUDY DESIGN

Cohort study (diagnosis); Level of evidence, 2.

METHODS

Established guidelines were used for translation and adaptation. The Turkish version of the MTSS (MTSS-Tr) score was completed twice with a 1-week interval between assessments. In the first assessment, patients also completed the Turkish version of the 36-Item Short-Form Survey (SF-36-Tr) and a visual analog scale (VAS) for pain. Test-retest reliability and internal consistency of the MTSS-Tr were measured with the intraclass correlation coefficient (ICC) and Cronbach α coefficient, respectively. The construct validity was demonstrated with the Spearman correlation coefficient ( ).

RESULTS

A total of 48 participants were included in the study. The test-retest reliability was good and internal consistency was good (ICC, 0.9; Cronbach α, 0.884). The MTSS-Tr score was highly negatively correlated with the physical component score of the SF-36-Tr ( = -0.716; < .001). There was a moderate correlation between the MTSS-Tr score and the VAS pain score ( = 0.465; = .001).

CONCLUSION

The translated MTSS-Tr score has good internal consistency and good reliability and validity. Therefore, the MTSS-Tr score is useful to evaluate symptoms in patients with MTSS.
