Background and Purpose: Tibialis posterior tendinopathy can lead to debilitating dysfunction. This study examined the effectiveness of orthoses and resistance exercise in the early management of tibialis posterior tendinopathy.
Subjects: Thirty-six adults with stage I or II tibialis posterior tendinopathy participated in this study.
Methods: Participants were randomly assigned to 1 of 3 groups to complete a 12-week program of: (1) orthosis wear and stretching (O group); (2) orthosis wear, stretching, and concentric progressive resistive exercise (OC group); or (3) orthosis wear, stretching, and eccentric progressive resistive exercise (OE group). Preintervention and postintervention data (Foot Functional Index, distance traveled in the 5-Minute Walk Test, and pain immediately after the 5-Minute Walk Test) were collected.
Results: Foot Functional Index scores (total, pain, and disability) decreased in all groups after the intervention. The OE group demonstrated the most improvement in each subcategory, and the O group demonstrated the least improvement. Pain immediately after the 5-Minute Walk Test was significantly reduced across all groups after the intervention.
Discussion and Conclusion: People with early stages of tibialis posterior tendinopathy benefited from a program of orthosis wear and stretching. Eccentric and concentric progressive resistive exercises further reduced pain and improved perceptions of function.
