Abstract
Medial Tibial Stress Syndrome (MTSS), commonly known as "shin splints," is a prevalent lower extremity injury, especially among runners. This study investigates the prevalence and associated risk factors of MTSS among professional runners in Peshawar, Pakistan. Conducted at Qayyum and Hayatabad Sports Complexes, the cross
-sectional study involved 46 participants, both male and female, aged 15 to 40 years. The results revealed that 41.30% of the participants experienced MTSS. Notable risk factors included reduced calf girth, decreased ankle dorsiflexion, higher Foot Posture Index (FPI-6) scores, and training on hard surfaces such as roads. Additionally, abnormal biomechanical variables, such as limited range of motion (ROM) in the hip, knee, and ankle joints, were significantly associated with MTSS. The findings underscore the importance of addressing modifiable risk factors such as muscle strength, flexibility, and training conditions to reduce MTSS prevalence in professional athletes.
