INTRODUCTION Neurologic paralysis of the foot due to damage to the central nervous system is primarily caused by a cerebral insult. The ankle-foot orthosis (AFO), which is the classical conservative treatment option, is associated with drawbacks, e.g., increased contractures, limited mobilization from the sitting position, and cosmetic aspects. METHODS Functional external electrostimulation (FES) is an suitable treatment method for patients with a central lesion and intact peroneal nerve. Based on this method, the neuroprosthesis is a dynamic therapy option in the form of an implantable nerve stimulator (ActiGait® system, Otto Bock, Duderstadt, Germany) which is placed directly on the motor branch of the peroneus nerve and results in active foot lifting. The aim of the present study is to evaluate the clinical effect of the ActiGait® system with regard to its suitability for everyday use by means of gait tests with an emphasis on time-distance parameters and to compare it with the current literature. RESULTS AND CONCLUSION In this retrospective study, the clinical results after implantation of the ActiGait® system are presented and evaluated. In summary, the implantation of a neuroprosthesis in patients with stroke-related drop foot represents a sensible and promising therapy option.

Ruptures of the tendon of the tibialis anterior muscle tend to occur in the context of degenerative impairments. This mainly affects the distal avascular portion of the tendon. Owing to the good compensation through the extensor hallucis longus and extensor digitorum muscles, diagnosis is often delayed. In addition to the clinical examination, magnetic resonance inaging (MRI) diagnostics are of particular importance, although damage or rupture of the tendon can also be demonstrated sonographically. Therapeutic measures include conservative or operative measures, depending on the clinical symptoms. Conservative stabilization of the ankle can be achieved by avoiding plantar flexion using a peroneal orthosis or an ankle-foot orthosis. Subsequent problems, such as metatarsalgia or overloading of the medial foot edge can be addressed by insoles or a corresponding shoe adjustment. An operative procedure is indicated when there is corresponding suffering due to pressure and functional impairment. The direct end-to-end reconstruction of the tendon is only rarely possible in cases of delayed diagnosis due to the degenerative situation and the retraction of the tendon stumps. Depending on the defect size and the tendon quality, various operative techniques, such as rotationplasty, free transplants or tendon transfer can be used.
