What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| DPN group | Patients with type 2 diabetic peripheral neuropathy were categorized into the DPN group | |
| Diabetic group | patients with type 2 diabetes mellitus but not with DPN were distributed into the Diabetic group. | |
| control group | The other individuals without type 2 diabetes mellitus were selected as the control group |
What is being measured
The primary outcome is the main question the study is designed to answer.
the severity of DPN
The nerve conduction examination was conducted at a room temperature of 24℃, with the legs warmed using an electric heating pad for at least 10 minutes to achieve a skin temperature of 32-35℃. The nerve conduction velocities and nerve conduction amplitudes were measured for both sides of the upper and lower limbs, including motor and sensory branches of the median nerve; motor and sensory branches of the ulnar nerve; motor branch of peroneal nerve; motor branch of the tibial nerve; sensory branch of the superficial peroneal nerve. In addition, both sides of the tibial nerve F-wave were recorded, and the lower one was regarded as the final F-wave. Slowed/blocked nerve conduction was defined as more than 2.5 standard deviation below the control nerve conduction threshold. Nerve conduction is defined as abnormal when two or more nerve abnormalities are detected.
Measured: From admission to discharge, up to 1 week
the presence of DPN
When any of the elements of the screening process -- symptoms, signs, or abnormal nerve conduction parameters --was abnormal, medical records would be scrutinized to see if these participants had accepted a previous DPN diagnosis by a specialist.
Measured: From admission to discharge, up to 1 week
