Diagnostic Tests for Foot paresthesia
Diagnostic Test list for Foot paresthesia:
The list of diagnostic tests
mentioned in various sources as
used in the diagnosis of Foot paresthesia
- Physical examination
- Feel the pulses in the legs - if reduced or absent should suggest peripheral atherosclerosis (hardening of the arteries) or obstruction of the abdominal aorta and its branches by atherosclerosis.
- Examine for a positive straight leg raising test (straightening the leg at the knee while lying on a bed causing pain in thigh, buttock and back) - indicates herniated disk of L4-5 or L5-S1, lumbar spondylosis, spinal stenosis, cauda equina tumor or spondylolisthesis.
- Examine for a positive femoral stretch test (with the person laying on their stomach, flex knee with hip lifted in extension causes pain in the front of the thigh and the back) - indicates a herniated disk of L3-4 or L2-3 or lumbar spondylosis.
- Examine the peripheral reflexes. If diffusely overactive may suggest multiple sclerosis, pernicious anemia, spinal cord tumor, syringomyelia (presence of cavities within the spinal cord) or anterior spinal artery occlusion. If diffusely under active may suggest peripheral neuropathy, poliomyelitis, Guillain-Barre syndrome, cauda equina tumor, metastatic tumor of the lumbar spine and occasionally pernicious anemia or peroneal neuropathy (disease of the peroneal nerve)
- Blood tests
- Full blood test and ESR
- Blood glucose and/or glucose tolerance test to rule out diabetes if peripheral neuropathy is present
- Arthritis screen (including Rheumatoid factor, ANA, ENA and ds DNA autoantibodies)
- B12 and folic acid levels
- Thyroid function tests to rule out hypothyroidism and hyperthyroidism
- Serum protein electrophoresis to diagnose various collagen vascular diseases that may cause neuropathy
- Syphilis serology, if indicated
- HIV test, if indicated
- Lead or arsenic levels, if suspect lead or arsenic neuropathy
- Urine tests
- Porphyrins and porphobilinogen to rule out Porphyria
- Radiological investigations
- X-Ray of the lumbosacral spine
- CT Scan of the lumbosacral spine
- MRI Scan of the lumbosacral spine, may be necessary
- Myelography may be useful when contemplating surgery
- Bone Scan may be helpful in diagnosing occult fractures, metastases or osteomyelitis
- Nerve conduction velocity study - to establish the presence of a neuropathy.
- Electromyelogram (EMG) - to establish the presence of a neuropathy.
- Spinal tap - if suspect multiple sclerosis, Guillain-Barre syndrome or neurosyphilis.
- Electrophysiological tests such as visual-evoked response (VER) - may be required to diagnose Multiple sclerosis.
- Lymph node biopsy - if sarcoidosis is suspected.
- Muscle biopsy - if suspect various collagen diseases.
