Sensokinetogram Functionality Measurement As A Diagnostic Aide In Carpal Tunnel Syndrome

Charles L. Metzger, MD, Greater Houston Orthopaedic Specialists, Houston, TX


I have recently been using a new FDA approved and patented device to help diagnose carpal tunnel syndrome. It is called a Sensokinetogram (SKG), which is a series of graphical and numeric outputs generated by the repetitive squeezing and holding (2 sec), then releasing (1 sec) a roll-of-quarters shaped device for 1 minute (20 cycles). The test is repeated, and then two more times for the other hand, giving a complete bilateral exam in 4 minutes of test time and real time about 10-12 minutes. There is no pain, there are no needles or disposables, and my MA administers the test. This roll-of-quarters hand piece is connected by a thin cable to a laptop computer. The test is administered, and the laptop sends it via internet to the server in Stafford Texas, which processes the data, and outputs the test results within about 10 minutes on the secure server website. I then pull the neatly arranged 11 graphs per hand up on the website and go over the results with the patient. Patients are very impressed with this, and I am confident enough in the data that I do not feel I need EMGs for most patients with carpal tunnel. The data are output in .pdf format so they can be printed on our office printer and sent to the insurance company for supporting documentation. Reimbursement is good with the use of CPT 97750.
