Background:
Medial tibial stress syndrome (MTSS) can impair training and daily activities, underscoring the need for effective treatment. However, there's limited evidence on using lower-leg exercises for MTSS in recreational runners.
Purpose/Hypothesis:
The purpose of the present study was to determine whether adding lower-leg exercises to a multimodal therapeutic intervention improves the recovery from MTSS in recreational runners. It was hypothesized that adding lower-leg exercises to a multimodal therapeutic intervention would enhance its effect on foot posture and make MTSS recovery more effective than multimodal therapeutic interventions alone.
Study Design:
Randomized controlled trial; Level of evidence, 1.
Methods:
A total of 40 recreational runners diagnosed with MTSS using history and physical examination (40% women; mean ± SD age, 23.9 ± 3.9 years) were then randomly divided into intervention (n = 20) and control (n = 20) groups. Both groups underwent a multimodal therapeutic intervention involving ice massage, foot orthoses, and extracorporeal shockwave therapy. The intervention group additionally received a tailored lower-leg exercise protocol involving stretching, strengthening, sensorimotor exercises, and foam roller myofascial release. Pain intensity, MTSS severity, perceived treatment effect, quality of life (QoL), and static and dynamic foot posture were assessed at baseline, 6-week, and 12-week follow-up evaluations.
Results:
A mixed model analysis of variance found no significant differences in pain intensity (P = .17) or MTSS severity (P = .30) between the intervention group and the control group. However, there were significant improvements in QoL (P = .003), static foot posture index (FPI) (P = .02), and dynamic arch index (DAI) (P < .001), for the intervention group. After 6 and 12 weeks, the intervention group displayed lower DAI scores than controls (P = .04 and P = .02, respectively). By week 12, the intervention group exhibited significantly higher QoL scores (P = .02) and lower FPI scores (P = .04) compared with controls.
Conclusion:
The study demonstrated that lower-leg exercises within a multimodal treatment positively affected foot posture and QoL, although they did not significantly alleviate pain or affect MTSS severity in recreational runners. Therefore, health care providers are encouraged to integrate these exercises into rehabilitation programs to improve foot posture and QoL for individuals with MTSS. However, future research should focus on larger sample sizes, objective measures, resting control groups, and longer follow-up periods to enhance the understanding of the effects of lower-leg exercises on MTSS management.
