AMTI and NeuroCom International have partnered together to create a computerized dynamic platform specifically tailored to the needs of the research community. The NRS's menu-driven operating system provides users with the ability to design research protocols featuring dynamic sensory and motor conditions that emulate real world challenges to balance, mobility and gait control. The integrated AMTI Dual Top force plate provides detailed measurements of the forces (X, Y, and Z components) required to accurately demonstrate the impact of those challenges on human performance.

NRS components include:

Research Software Package

User-programmable operating system provides flexibility in designing research protocols. Users can specify:

Performance Characteristics

Servomotors provide smooth, accurate movements of the AMTI Dual Top force plate. Users can define the control parameters for the servomotors, which can be activated individually or in pairs.

Force plate movements and data acquisition can be initiated either under operator control or by an external synch pulse. A sync-out pulse is also available to synchronize external devices.
