Computerized gait evaluation in patients with surgically repaired Achilles tendon ruptures

Abstract

The aim of this study was to evaluate the gait of 15 patients with surgically repaired acute Achilles tendon ruptures, before and after the rehabilitation treatment and to demonstrate the impact of this evaluation in establishing functional treatment.
Material and Method. We prospectively evaluated 15 cases of surgically repaired Achilles tendon ruptures. The assessment was made after cast removal and then after 1, 3 and 6 months of rehabilitation treatment. In order to evaluate gait we used a Zebris CMS-HS system, ultrasound-based system and a Zebris FDM system, a plantar pressure device. We also used the heel-rise test and measured calf circumference.
Results. The results of the first assessment were the base in establishing the following rehabilitation treatment. After the first month of rehabilitation treatment there were some improvements in ankle mobility, calf circumference and gait parameters. After 6 months of rehabilitation treatment we noted a significant decrease of the step time and enhancement of the walking speed and cadence. The ankle mobility enhanced, especially plantar flexion during the supporting phase. There was a better load of the lateral border, metatarsal heads and hallux. The heel-rise test was significantly improved. Ankle stability increased after the rehabilitation treatment, in most patients.
Conclusions. Zebris CMS-HS system allows quick and simple analysis of the most important gait parameters being a noninvasive tool. The rehabilitation treatment was important because it increased ankle stability increasing patients’ confidence in returning to sports.
