NeuroPath Comparative Validation Study Plan

Exclusion Criteria

• •Sensory symptoms exclusive or predominatly in the little finger (D5) (ulnar neuropathy).
• •Neck pain or shoulder pain preceded the paresthesia in the digits (cervical radiculopathy and/or brachial plexopathy).
• •Numbness and/or tingling in the feet that preceded or accompanied the sensory symptoms in the hands (polyneuropathy).
• •Medical history and physical examination that indicates an explanation for the sensory symptoms which is more probable than CTS. For example, digital neuropathy, median nerve pathology proximal to the carpal tunnel, ulnar neuropathy, radical neuropathy, brachial plexopathy, cervical radiculopathy, spinal cord, brainstem or brain pathology, or a polyneuropathy.
• •Absence of 1st, 3rd, 4th or 5th digits
• •Open wounds at the measurement sites
• •Excessive sensitivity to electrical stimulation
• •Median nerve injection in the past 30 days
• •Prior carpal tunnel surgery
• •Patients who are susceptible to radio frequency noise - such as patients with pacemakers or patients that have electrical stimulators of any sort.
• •Absence of 1st, 3rd or 5th digits
• •Open wounds at the measurement sites
• •Excessive sensitivity to electrical stimulation
• •Median nerve injection in the past 30 days
• •Prior carpal tunnel surgery
• •Reported history of CTS, polyneuropathy, diabetes,renal failure, thyroid disease or Vitamin B 12 deficiency
• •Patients who are susceptible to radio frequency noise-such as patients with pacemakers or patients that have electrical stimulators of any sort.
