The Effect of Bracing and Strengthening Exercises on Posterior Tibial Tendon Dysfunction
In Brief
A Phase 2 clinical trial evaluating Bracing, Strengthening exercises, and 1 other intervention for Posterior Tibial Tendon Dysfunction. Completed, enrolled 39 participants across 1 site.
Detailed Summary
Posterior tibial tendon dysfunction (PTTD) is a problem with the tendon connecting one of the lower leg muscles to the foot bone. PTTD can cause pain, swelling, and a flattened foot and may require surgery if left untreated. Normal treatment for PTTD includes physical therapy exercise. In treating similar conditions in the lower leg, exercises that are active, like strengthening, seem to have better results than exercises that are passive, like stretching. This study will determine whether adding strengthening exercises to a normal PTTD treatment that includes wearing a brace and stretching is more beneficial than just wearing a brace and stretching.
Study Details
Timeline
Interventions
Participants will wear a brace that includes ankle stirrup support and medial longitudinal arch support. The brace will be worn during weight-bearing tasks throughout the 12-week study.
Participants performed strengthening exercises progressively longer each time for up to 3 sets of 30 repetitions twice daily by the third visit. Exercises included bilateral heel raises, foot adduction/rear foot inversion with thera-tubing, and unilateral heel raises. Participants increased resistance by using thera-bands with higher levels of resistance over the 12 week period. The amount of resistance was progressed according to patient tolerance at each visit. Strengthening exercises were preceded by the control stretching exercises which constituted a "warm up."
Subjects were provided with written descriptions and pictures demonstrating 2 range-of-motion exercises which included a wall calf stretch, and a supine ankle active range-of-motion exercise. Subjects were instructed to perform 3 sets of the stretching exercises, 2 times a day, similar to the intervention group. Each stretching exercise was performed twice and held for 30 seconds.
