Relationships between Medial Tibial Stress Syndrome and Physical Functions in Long-distance Runners

[Purpose] To develop preventive perspectives on medial tibial stress syndrome (MTSS), university long-distance runners’ status of injury and physical functions related to the history of MTSS, specifically the influences of pedal edema, were examined. [Participants and Methods] A questionnaire survey was conducted, involving 50 long-distance runners to perform various types of measurement in 12 (6 males and 6 females) randomly selected. The measurement items were: the leg volume, Shin oedema test (SOT) score, hip internal and external rotation ranges of motion, and fallen arch distance. [Results] Among the 50 runners, 40 had a history of MTSS. The diurnal variation in the leg volume was more marked in the MTSS than control group. There were no differences in the other measurement items. [Conclusion] Runners with a history of MTSS may be more vulnerable to swollen leg and MTSS.
