The Diabetic Sensorimotor Polyneuropathy (DSPN) is a symmetrical, length-dependent sensorimotor polyneuropathy attributable to metabolic and microvessel alterations as a result of chronic hyperglycemia exposure (diabetes) and cardiovascular risk covariates.
Definitions of minimal criteria for DSPN1. Possible Clinical DSPN
Symptoms or signs of DSPN. Symptoms may include: decreased sensation, positive neuropathic sensory symptoms (e.g. ‘asleep numbness’, ‘prickling’ or ‘stabbing’, ‘burning’ or ‘aching’ pain) predominantly in the toes, feet, or legs. Signs may include: symmetric decrease of distal sensation or unequivocally decreased or absent ankle reflexes.
2. Probable Clinical DSPN
A combination of symptoms and signs of distal sensorimotor polyneuropathy with any two or more of the following: neuropathic symptoms, decreased distal sensation, or unequivocally decreased or absent ankle reflexes.
3. Confirmed Clinical DSPN
An abnormal nerve conduction study and a symptom or symptoms or a sign or signs of sensorimotor polyneuropathy. Severity of DSPN can be assessed by staged or continuous approaches described above and by dysfunction and disability scores.
4. Subclinical DSPN
No signs or symptoms of polyneuropathy. Abnormal nerve conduction, as described above, is present.
Dyck's Stages of Severity for DSPN
An alternative approach to estimating severity is to indicate severity by grades:
