title: [Effect of external stabilization aids of the upper ankle joint on sports-specific performance with reference to isokinetic strength measurements].
abstract: Two questions were investigated: Do ankle devices have any influence on sports performance? Are there any differences between the devices? 31 participants could be included. The average age was 24.5 (+/- 4.1). The participants exercised 5.8 hours/week. We tested 41 ankles without any previous injury. With the Cybex 6000 four parameters were evaluated. Torque maximum for the plantarflexion, range of motion, work in Joule. The ankles were tested with three different ortheses, ankle taping and without any device. The Friedman Test was used to evaluate differences between the five test conditions. All measurements showed significant worse results for the devices and taping. The protective effect of ankle devices is well known. In this investigation we could show a restriction of the performance. Thus it should be decided individually, if an ankle device is useful.
