Efficacy of Integrated Neuromechanical Rehabilitation on Symptom Resolution and Recurrence Rates in Medial Tibial Stress Syndrome: A Randomized Controlled Trial

Abstract Background: Medial tibial stress syndrome (MTSS) affects 4-35% of runners with substantial recurrence rates ranging from 25-57% following standard care protocols. While individual interventions (load management, gait retraining, strengthening) demonstrate independent efficacy, high-quality randomized controlled trial evidence evaluating integrated models combining all three components remains limited in the current literature. Objective: To evaluate the comparative efficacy of integrated neuromechanical rehabilitation (INR) versus standard care (SC) on pain reduction, functional recovery, objective biomechanical changes, and recurrence prevention in recreational runners with medial tibial stress syndrome. Methods: One hundred twelve recreational runners aged 18-45 years with clinically and imagistically confirmed MTSS were randomized to INR (n=56) or SC (n=56). The INR group received 12 weeks of structured load management, real-time gait retraining with biomechanical feedback utilizing force plate analysis, and periodized neuromuscular training specifically targeting tibialis posterior, soleus, and intrinsic foot musculature. The SC group received conventional management including activity modification, standard stretching protocols, and ice application. Primary outcomes assessed at 12 weeks included pain intensity (visual analog scale), time to return to full running activity, and tibial shock attenuation verified through force plate analysis. Secondary outcomes encompassed functional capacity (Lower Extremity Functional Scale), ankle strength measurements, gait biomechanical parameters, and recurrence incidence documented at 6-month and 12-month follow-up assessments. Results: The INR group achieved significantly superior pain reduction (mean difference 4.2±0.8 points on VAS; 95% confidence interval [CI]: 2.8-5.6; p<0.001; Cohen's d=1.82). Time to return to full running activity was substantially shortened in INR (mean 6.8±1.4 weeks versus 14.2±3.1 weeks in SC; p<0.001; Cohen's d=2.74). Objective biomechanical analysis revealed greater peak tibial shock reduction in INR (mean difference 0.34±0.09g; 95% CI: 0.22-0.46; p<0.001; Cohen's d=3.71), representing a 15.2% reduction compared to 2.5% in SC. Functional capacity improvements favored INR (mean difference 18.3±4.2 points on LEFS; 95% CI: 14.1-22.5; p<0.001). Loading rate reduction substantially favoured INR (mean difference 78.4±22.1 N/s; 95% CI: 52.1-104.7; p<0.001). Most significantly, recurrence rates were dramatically lower in INR at both 6-month (7.1% versus 32.1%; p<0.001) and 12-month (10.7% versus 46.4%; p<0.001) follow-up assessments. Eversion strength gains substantially exceeded inversion in INR, suggesting superior neuromuscular control restoration. No serious adverse events occurred in either group. Conclusion: Integrated neuromechanical rehabilitation demonstrates superior efficacy compared to standard care for medial tibial stress syndrome management, producing rapid pain resolution, expedited return to competitive activity, verified objective biomechanical improvements, and substantial long-term recurrence prevention. Combined interventions targeting load optimization, gait mechanics normalization, and targeted neuromuscular control enhancement represent the optimal clinical strategy for MTSS rehabilitation and injury prevention. Current findings strongly support integration of biomechanical assessment and systematic gait retraining as standard components in MTSS management protocols across diverse clinical settings.
