Features and Advantages
The NeuroFlexor is composed of a servo motor and force sensor coupled to a portable computer. Passive limb displacements are produced at controlled velocities. Resistance is measured accurately using a force sensor. The resulting resistance trace is then analyzed according to a biomechanical model. The biomechanical model describes how various mechanical components in the stretched muscle and the resulting neural activation by the stretch reflex contribute to the resistance produced during stretching. This new model for estimation of spasticity components has been validated and the findings have been published in the journal Neurorehabilitation Neural Repair (2011).
