Neuropathic Pain Symptom Inventory
scale for neuropathic pain symptoms. A total intensity score can be calculated as the sum of the scores of the 10 descriptors. In addition, we propose to derive five subscores corresponding to the mean scores of the items belonging to each of the five factors identified in the factor analysis. three questions based on clinical examination to evaluate the intensity of pain evoked by brushing, pressure, cold or warm stimuli in the painful area on four-point categorical scales (absent, mild, moderate, severe). Clinical examination of evoked pain was standardized: tactile allodynia was evaluated with a soft brush (three movements), pressure allodynia was evoked by blunt pressure with a finger at a pressure that does not provoke pain in a normal area and glass tubes filled with hot (38-408C) or cold (22-248C) water were used to evaluate thermal allodynia.
Time frame: 6 months
PAIN Detect score
score for neuropathic pain, higher values indicate that the pain is neuropathic. A Pain DETECT score between-1 and 38 indicates the likelihood of a neuropathic pain component
Time frame: 6 months
Visual Analogue scale
scale for pain , higher values indicate more severity of pain, scale 0-100
Time frame: 6 months
Nerve conduction velocity
neurophysiological assessment of sural nerve
Time frame: 6months
Vibration perception threshold
Vibration perception threshold was measured with biothesiometer
Time frame: 6 months
