This test measures how quickly the nerves in the arms and legs conduct electrical signals. The SWMT is a common evaluation tool for evaluating sensory function and loss of pressure sensation (perception of light touch) (appendix). The size of the monofilament includes 0.5 g, 2 g, 10 g, 50 g, 200 g and other different types, which indicate the magnitude of the force exerted on the monofilament when the monofilament is freshly folded. The 10 g monofilament test (also called 5.07 monofilament) is the most common in practice (Boulton 2004; Valk 199).
The doctor may also perform other tests for diabetic neuropathy to diagnose diabetic neuropathy and determine the extent of nerve damage. These tests for diabetic neuropathy may include nerve conduction tests, electromyography (EMG), quantitative sensory tests (QST), heart rate variability, ultrasound, and nerve or skin biopsy. Healthcare providers diagnose neuropathy as diabetes-related if you have diabetes and can't find another cause. You'll also need to visit your diabetes professional (such as an endocrinologist) regularly to make adjustments to your diabetes management plan. A diabetic foot exam can help detect problems that can lead to serious infection and amputation (surgery to remove all or part of the foot) if not found and treated on time.
Diabetes can cause long-term complications, such as retinopathy, nephropathy, neuropathy, and other vascular complications (American Diabetes Association 201). If you have diabetes, the chance of developing diabetes-related neuropathy increases as you age and have been suffering from diabetes longer. To start, a healthcare provider will ask you detailed questions about your medical history and diabetes management. Diabetic neuropathy is the clinical field in which QST has been most frequently applied, and it encompasses all aspects of neuropathy, from diagnosis to treatment.
If you're suspected of having diabetes, they can usually make a reliable diagnosis based on symptoms, a physical exam, and monitoring blood and urine sugar levels. The diagnosis of diabetic neuropathy is based on the symptoms mentioned above, as well as a physical examination: blood pressure and heart rate, muscle strength, reflexes, sensitivity to position, vibration, temperature, or light touch. People with diabetes usually need to have a complete diabetic foot exam at least once a year to help prevent serious infections. If blood sugar is better controlled, symptoms of diabetes-related neuropathy, such as numbness and other abnormal sensations, may disappear within a year.
Research shows the importance of the QST test for diabetic neuropathy for the early detection of dysfunctional myelinated fibers in neuropathy diabetic. Studies show that peripheral neuropathy affects at least 20% of people with type 1 diabetes who have had diabetes for at least 20 years. A study conducted on people with type 2 diabetes shows that having an A1C level greater than 7% for at least three years increases the risk of diabetes-related neuropathy. Diabetic neuropathy is a common complication of diabetes caused by damage to nerve fibers caused by high sugar levels.
