摘要

Background

Medial tibial stress syndrome (MTSS) is a common overuse injury among recreational runners that frequently results in pain-related functional limitations. This study aimed to examine the association between pain intensity and lower extremity functional limitations in college athletes with clinically diagnosed MTSS while adjusting for potential confounders.

Methods

A total of 100 recreational college athletes (55 men, 45 women) with clinically diagnosed medial tibial stress syndrome (MTSS) (mean age, 21.4 ± 1.7 years) were evaluated in this cross-sectional study via the 11-point Numeric Pain Rating Scale (NPRS) and the lower extremity functional scale (LEFS). We conducted Pearson correlation and multiple linear regression analyses to assess the relationships between pain intensity and lower extremity function while controlling for age, sex, running distance, history of MTSS, foot posture, type of footwear and running surface.

Results

Pain intensity was significantly negatively correlated with lower extremity function (r =  − 0.390, p < 0.001). After adjusting for confounders in multiple linear regression, NPRS remained an independent predictor of LEFS score B =  − 4.05, p < 0.001), explaining approximately 19.8% of the variance.

Conclusion

In recreational college athletes with MTSS, greater pain intensity is independently associated with greater functional limitations. These findings underscore the importance of pain assessment in this population and support the inclusion of pain-modifying interventions in rehabilitation programs, although longitudinal studies are needed to establish causality.
