[Biomechanical Evaluation of Rehabilitation after Surgical Repair of Achilles Tendon Ruptures].

 Muscles and tendons are subjected to a high level of stress in everyday life and sports. This often leads to injuries and is associated with training failure and reduced performance as well as with high costs for treatment and rehabilitation. Fast and successful treatment is therefore very important, both from an athletic and economic point of view.

Influence of calcaneus angle and muscle forces on strain distribution in the human Achilles tendon.

Background: Heterogeneous distribution of tendon strain is considered to contribute to the development of the Achilles tendon overuse injuries. Force distribution between the three portions of the triceps surae muscle and position of the calcaneus might affect the extent of strain differences within the Achilles tendon. Purpose of this study was to determine the effect of changes in force distribution within the triceps muscle and changes in calcaneus position on intratendinous strain distribution of the Achilles tendon.

[The functional sport shoe parameter "torsion" within running shoe research--a literature review].

Within the sport shoe area torsion is described as the twisting and decoupling of the rear-, mid- and forefoot along the longitudinal axis of the foot. Studies have shown that running shoes restrict the torsion of the foot and thus they increase the pronation of the foot. Based on the findings, it is recommended to design running shoes, which allow the natural freedom of movement of the foot.

Intraarticular pressure distribution in the talocrural joint is related to lower leg muscle forces.

Background: It is of paramount importance to know the magnitude and the distribution of joint contact stress within the most heavily loaded structures of the human foot. In the talocrural joint role of external loading and loading applied by muscles on joint contact stress is not extensively studied. The purpose was to determine the distribution of joint contact stress of the talocrural joint with varying axial tibia loading and extrinsic tendon loading.

Efficacy and tolerability of escin/diethylamine salicylate combination gels in patients with blunt injuries of the extremities.

The aim of this confirmative, monocentre, double-blind, controlled clinical trial was to investigate whether different escin combinations show differences in comparison to placebo with regard to pain reactions in the topical treatment of sports injuries. A total of 126 patients with blunt injuries of the extremities were randomly allocated to four parallel groups: Reparil-Gel N (n = 32), Reparil-Gel (n = 31), Reparil-Sportgel (n = 32) and a placebo gel (n = 31). All patients were evaluated for efficacy (intention to treat) and tolerability.
