![]() ![]() 3 and was found to be suitable for screening for sensation loss.Ĭonsidering the simple and inexpensive nature of the graduated tuning fork, we evaluated its usefulness in screening for vibratory sensation loss in non-diabetic and diabetic subjects, compared with the values obtained with biothesiometer, a commonly used but expensive device. The performance of a graduated tuning fork of Rydel and Seiffer had been evaluated by Liniger et al. ![]() A simple inexpensive method which would pick up loss of sensation in the feet could be used by the physicians treating diabetic patients, as a screening procedure to detect a high-risk foot. 1, 2 Foot lesions in diabetes contribute to lower extremity amputations and severe morbidity. Copyright © 2001 John Wiley & Sons, Ltd.ĭiabetic peripheral neuropathy with loss of sensation is a major sequalae of diabetes which is closely associated with foot ulceration. This study shows that the graduated tuning fork has a high specificity and a fairly good sensitivity in the diagnosis of diabetic foot problems. Tuning fork scores were normal in all the 471 non-neuropathy cases, thus giving a specificity of 100%. Among the 455 patients identified as having neuropathy by abnormal biothesiometric values, 235 had an abnormal tuning fork score of ≤4.0. Patients with neuropathy had a lower mean score of 4.5☒.6 compared with the non-neuropathy cases (7.7☐.5, P<0.001). ![]() The vibration perception scores were tested in 195 non-diabetic healthy control subjects ( n=195, M:F, 80:115, Mean±SD, age 50.3☑0.4 (years), in 455 Type 2 diabetic subjects who had signs and symptoms of sensory neuropathy and abnormal biothesiometric readings (reading>25V), (n=455, M:F 326:129, Mean Age 58.1☗.7 years, HbA1c 10.1☒.4%) and in 471 diabetic patients with no evidence of neuropathy by biothesiometry. Considering the simple and inexpensive nature of the graduated tuning fork, we evaluated its usefulness in screening for vibratory sensation loss in non-diabetic and diabetic subjects, compared with the values obtained with biothesiometer. ![]()
