Objectives
At the end of the presentation the participant will be able to: • Define the risk factors associated with
diabetic neuropathy. • Define the classifications of diabetic
neuropathy. • Illustrate the treatment options for the
various classifications. • Complete a foot assessment.

Diabetic Neuropathy • About 60-70% of people with
diabetes have mild to severe forms of nervous system damage, including:
- Impaired sensation or pain in the feet or hands
- Slowed digestion of food in the stomach
- Carpal tunnel syndrome
- Other nerve problems
• More than 60% of nontraumatic lower-limb amputations in the United States occur among people with diabetes.

Risk Factors
• Glucose control
• Duration of diabetes
• Damage to blood vessels
• Mechanical injury to nerves
• Autoimmune factors
• Genetic susceptibility
• Lifestyle factors – Smoking
– Diet

Classification of Diabetic Neuropathy
• Symmetric polyneuropathy
• Autonomic neuropathy
• Polyradiculopathy
• Mononeuropathy
![Page 6: neuropathy and foot exam haiti - CRUDEM](https://reader030.fdocuments.us/reader030/viewer/2022012014/615984fea4b9066cef57c74a/html5/thumbnails/6.jpg)
Symmetric Polyneuropathy
• Most common form of diabetic neuropathy
• Affects distal lower extremities and hands (“stocking-glove” sensory loss)
• Symptoms/Signs – Pain
– Paresthesia/dysesthesia
– Loss of vibratory sensation

Diagnostic Tests
• Assess symptoms - muscle weakness, muscle cramps, prickling, numbness or pain
• Comprehensive foot exam – Skin sensation and skin integrity
– Quantitative Sensory Testing (QST)
– X-ray
• Nerve conduction studies
• Electromyographic examination (EMG)
![Page 10: neuropathy and foot exam haiti - CRUDEM](https://reader030.fdocuments.us/reader030/viewer/2022012014/615984fea4b9066cef57c74a/html5/thumbnails/10.jpg)
Complications of Polyneuropathy
• Ulcers
• Charcot arthropathy
• Dislocation and stress fractures
• Amputation - Risk factors include: – Peripheral neuropathy with loss of protective
sensation
– Altered biomechanics (with neuropathy)
– Evidence of increased pressure (callus)
– Peripheral vascular disease
– History of ulcers or amputation
– Severe nail pathology

Treatment of Symmetric Polyneuropathy
• Glucose control
• Pain control – Tricyclic antidepressants
– Topical creams
– Anticonvulsants
• Foot care
![Page 12: neuropathy and foot exam haiti - CRUDEM](https://reader030.fdocuments.us/reader030/viewer/2022012014/615984fea4b9066cef57c74a/html5/thumbnails/12.jpg)
Essentials of Foot Care • Examination – Annually for all patients
– Patients with neuropathy - visual inspection of feet at every visit with a health care professional
• Advise patients to: – Use lotion to prevent dryness and cracking
– File calluses with a pumice stone
– Cut toenails weekly or as needed
– Always wear socks and well-fitting shoes
– Notify their health care provider immediately if any foot problems occur

Treatment
• Antidepressant drugs – amitriptyline 25-150 mg qhs
– doxepin
– duloxetine
• Antiseizure medications – gabapentin
– pregabalin 50-100 mg tid (decrease in CKD
– carbamazepine
– Valproate

Treatment
• Caspsasin cream

Stimulation)

Polyradiculopathy • Lumbar polyradiculopathy (diabetic
amyotrophy) – Thigh pain followed by muscle weakness
and atrophy
• Thoracic polyradiculopathy – Severe pain on one or both sides of the
abdomen, possibly in a band-like pattern
• Diabetic neuropathic cachexia – Polyradiculopathy + peripheral neuropathy
– Associated with weight loss and depression

• Polyradiculopathies are diagnosed by electromyographic (EMG) studies
• Treatment – Foot care
– Glucose control
– Pain control
![Page 18: neuropathy and foot exam haiti - CRUDEM](https://reader030.fdocuments.us/reader030/viewer/2022012014/615984fea4b9066cef57c74a/html5/thumbnails/18.jpg)
Mononeuropathy • Peripheral mononeuropathy
– Single nerve damage due to compression or ischemia
– Occurs in wrist (carpal tunnel syndrome), elbow, or foot (unilateral foot drop)
– Symptoms/Signs • numbness
• edema
• pain
• prickling
![Page 19: neuropathy and foot exam haiti - CRUDEM](https://reader030.fdocuments.us/reader030/viewer/2022012014/615984fea4b9066cef57c74a/html5/thumbnails/19.jpg)
• Cranial mononeuropathy – Affects the 12 pairs of nerves that are
connected with the brain and control sight, eye movement, hearing, and taste
– Symptoms/Signs • unilateral pain near the affected eye
• paralysis of the eye muscle
• double vision
• Mononeuropathy multiplex
