NeuroMetrix gets updated FDA approval

Medical device maker NeuroMetrix Inc. said today that the Food and Drug Administration gave its NC-stat nerve conduction testing system updated clearance.

The system had already been approved for use in diagnosing neuropathies, such as carpal tunnel syndrome and diabetic peripheral neuropathy. Neuropathies include diseases that effect the nerves, often resulting in numbness and pain.

The system can now also be used to stimulate and measure neuromuscular signals in diagnosing and evaluating systemic and entrapment neuropathies. NeuroMetrix is based in Waltham. (AP)
