Prosthetic knee joint with stance control Exitus

microprocessor-controlleddynamicfor walking

Overview
The microprocessor-controlled knee module Exitus is a component designed for transfemoral (above-knee and hip-level) prostheses. Unlike a biological knee, the module regulates flexion and extension without direct knowledge of the user's intent. Exitus continuously collects and processes gait parameters and calculates in real time the required flexion and extension torque to control the joint. The module provides controlled stance and swing phases, stumble protection, adaptive speed response and secure negotiation of slopes and steps to support functional gait across varied conditions.

Key functions

• Automatic adaptation to the user’s gait pattern
• Real-time collection and processing of walking parameters
• Calculation and application of required flexion and extension torque
• Controlled stance (support) and swing (transfer) phases
• Stumble protection and improved safety on inclines and steps
• Adaptive response to changes in walking speed and loading
