NEUROMECHANIC is a simulated physical environment for testing the stability and control of musculoskeletal systems. Rigid body dynamic equations of motion, phenomenological muscle models, and simplified neuron models are incorporated.

NEUROMECHANIC was specifically developed to answer questions involving neural control of biomechanical stability. Toward this goal the software performs four major functions:

1. Given a musculoskeletal system in contact with the environment, the software calculates the muscle forces that would balance the external forces applied to the body (such as gravity) thereby putting the body in equilibrium
   
   
2. The software linearizes the equations of motion for a given body and posture at an equilibrium point and evaluates the Lyapunov stability of the system.
   
   
3. The software performs forward dynamic simulation of the musculoskeletal system for constant muscle activation patterns with feedback.
   
   
4. Users may design their own neural controller or muscle model in matlab or a dynamic linked library which can then be interfaced with NEUROMECHANIC
