Brief summary
Performance assessment of the PMD-200, a novel pain monitor, in subjects with degenerative lumbar spine disease who requires surgical procedure
Detailed description
The proposed study is design to further demonstrates the capability of the Nociception Level, (NoL) Index in identify and discriminate between painful event and non-painful period following pain stimulus of Straight Leg Raising (SLR) test in patients with degenerative lumbar spine disease. This feasibility study may provide first indication for a validation method that will be able to evaluate the outcome of a surgical procedure within the degenerative lumbar spine patient. Currently, there is lack of understanding of long-term outcomes after such surgeries. In this study, the investigators plan to demonstrate that the NoL Index may serve as an indicator to the surgical procedure outcome. It will compare the objective measurement of the NoL to the patient Visual Analogue Scale (VAS) score and disability questionnaire that will characterize the subject pain perception prior and following the surgical procedure.
Interventions
DEVICEPMD-200
The PMD-200 system is comprised of a console and designated finger probe with 4 sensors. The Sensors are Photoplethysmography (PPG) Galvanic Skin Response (GSR), Accelerometer (ACC) and Thermistor (TMP)
DIAGNOSTIC_TESTSLR
With the patient lying down on his/her back, the examiner lifts the patient's leg while the knee is straight.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| discrimination between nonpainful period to painful period | Through study completion, about one year | To demonstrate that the NoL index can discriminate between nonpainful period to painful period, prior and following SLR test |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Correlates with changes in pain levels | Through study completion, about one year | To demonstrate that the NoL Index is correlates with changes in pain levels of the subject prior and following SLR. |
