Peripheral neuropathy is just assessed by determination of Vibration sensation, pressure sensation, superficial pain or temperature. The most commonly used technique for diagnosis of peripheral neuropathy is nervous conduction (NC) and electromyography (EMG). But EMG/NC is bothersome and techniques using electric currents to measure NC and needles to study muscle innervations are uncomfortable.
Quantitative NeuroSensory Testing (QST) is essential in the evaluation of small-caliber A-delta and C-fibers, the primary transmitters of thermal and pain sensation. QST can demonstrate neurosensory abnormalities when it is non-invasive test, selective to small fibers despite negative EMG/NCV finding.
The investigators predict QST can be used for the early diagnosis and follow-up of small-fiber neuropathy in diabetes patients. The investigators also predict the early evaluation of diabetes neuropathy with QST can reduce the diabetes patient progress to advance stage of DM foot or limb amputation.
Patients will be divide into 4 groups (groups 1 to 4 will be divided by Q-Sense QST (TSA II) . The patient groups will be defined as the followings:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Q-Sense_QST (TSA II) | Other | QST measurement will perform on the thenar eminence of the dominant hand and the lateral distal aspect of the foot dorsum of the same side. Using the method of limits, a threshold will determine as the average of four successive stimuli for cold and warmth sensation and two for heat pain. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Q-Sense_QST (TSA II) | Device | QST will perform using the Medoc device (TSA2001/VSA3001) following previous published procedures. The measurement will perform on the thenar eminence of the dominant hand and the lateral distal aspect of the foot dorsum of the same side. |
