![]() TENS may be considered as a new way of evaluating DPN. So it is critical to find new ways of diagnosing DPN early. Testing for position sense probably does not need to be performed routinely however, position sense should be tested in all patients who have sensory symptoms, in patients who have significant sensory findings to vibration or pin, or in patients with a complaint of problems with gait or balance. This may lead to life threatening complications, like amputation. Denoting that tens is better than tuning fork in detecting vibration sense and early detection of diabetic peripheral neuropathy.Ĭonclusion: DPN is very common in diabetic patients but it may take a long time to be diagnosed. The vibration modes of tuning fork structure are used to complete the frequency up-conversion function. Comparing sensitivity and specificity of tens on right foot and tuning fork on right foot showing that tens has sensitivity of 94% and specificity 96% and tuning fork sensitivity of 83% and specificity 94 %. The results also show a statistically significant difference between diabetic patients and control by using 128 Hz tuning fork, in which there is significant decrease in vibration sense in diabetic patients in comparison to control. Results: The results show a statistically significant difference between diabetic patients and control by using TENS in which there is significant decrease in vibration sense in diabetic patients in comparison to control. a score of vibration perception graded from 0 (no sensation) to 8 loss of sensation after 8 seconds) when using a tuning fork. control group fell sensation up to 40 mA. According to results we can divide diabetic neuropathy to mild in which the patients fell sense from 40 mA to 60 mA, moderate in which the patients feel sense from above 60 mA to 80 mA, severe in which the patient feel sensation from above 80 mA to 100 mA. The measurements were taken at hallux on the right and left foot. The vibration sense testing using a tuning fork was Performed with a tuning fork with a free vibration frequency of 128 Hz. Using a 128 or 256 Hz tuning fork, place it at a distal joint (typically the interphalang. TENS units intensity ranges from 1 mA to 100 mA. This video demonstrates the technique for testing vibration sense. TENS probes were placed adjacent to the hallux. Here in this trial we chose 1 point in each foot: the hallux. ![]() In all patients (diabetic patients and controls), we evaluated the presence of peripheral neuropathy by using a 128 Hz tuning fork and TENS (Transcutaneous electrical nerve stimulation). Materials and methods: 100 patients into 2 parallel groups. conventional TENS act through stimulating large diameter (A-beta) nerve fibers. TENS is considered as a non-invasive, cheap technique. There are new methods to evaluate vibration sense and pressure sensation acting on Aβ, and C type fibres. Pacinian corpuscles consist of large myelinated A-beta fibers detecting high frequency vibration and deep pressure. Vibratory sense is perceived by mechanoreceptors, which have 2 types, Pacinian corpuscles and Meissner corpuscles. ![]() Introduction: When diabetes mellitus is diagnosed, peripheral neuropathy is present in about 20 % of cases.
