Abstract

OBJECTIVE:

To prospectively identify proximal risk factors contributing to the development of exertional medial tibial pain (EMTP).

METHODS:

Data were prospectively collected on healthy female students in physical education, who were freshmen in 2010-2011 and 2011-2012. 95 female students, aged 18.15 ± 0.84, were tested at the beginning of their first academic year. Testing included isokinetic hip strengthmeasurements of the abductors, adductors, internal rotators and external rotators. The follow-up of the individulas was assessed using a weekly online questionnaire and a 3-monthly retrospective control questionnaire. EMTP was diagnosed by an experienced MD (Doctor of Medicine). Cox regression analysis was used to identify the potential risk factors for the development of EMTP.

RESULTS:

21 individuals were diagnosed with EMTP during follow-up. The results of this study identified that decreased hip abductor concentricstrength is a predictive parameter for the development of EMTP in females. More specifically, total work (p=0.010) and average power (p=0.045) for concentric abduction strength were found to be significant predictors for this lower leg overuse injury.

CONCLUSIONS:

Hip abductor weakness is a significant predictor for EMTP in women. Preventive screening methods for EMTP should therefore include this proximal contributing factor.

Fuerza abductora cadera en dolor medial de tibia exercional

Hasta el momento no se han publicado estudios prospectivos que determinen factores de riesgo relacionados a la fuerza muscular asociados al dolor medial de tibia exercional (DMTE) en una población joven y físicamente activa.

El DMTE es un problema por sobreuso complejo y a la vez común, usualmente inducido por cargas repetitivas en la pierna inferior. Dentro de las características del DMTE destacan que es un cuadro exercional que causa dolor a lo largo del borde posteromedial de la tibia, y podría incluir dentro de sus posibles diagnósticos al síndrome de stress medial, fractura por stress tibial, síndrome compartimental crónico exercional y lesiones musculares / tendinosas.
