![]() ![]() 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. TENS units intensity ranges from 1 mA to 100 mA. 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.
