“…According to the results of the tactile sensation test, the threshold at the fifth toe (Point 3) was higher than the other four points both for CS and non-CS groups. Ino et al [14] tested the plantar sensation at the same points in this research and observed that the fifth toe had the highest plantar detection threshold, followed by the first metatarsal head. Surprisingly, we observed that young females with CS had a lower tactile threshold at the foot sole, opposite to the findings in the previous study.…”

“…In this research, five plantar points were selected as test points. To eliminate serial effects, the stimulation order was set as 1: first toe, 2: heel, 3: fifth toe, 4: first metatarsal head, 5: fifth metatarsal head [14]. White circles denote the test points, and the dotted line with a single arrow denotes the stimuli order.…”

Cold sensation (CS) is a cold feeling on people’s hands or feet; this is a well-known health problem for young females. Plantar tactile sensation plays an important role in postural control and is affected by skin temperature. However, there is no research focusing on the relation between CS and plantar tactile sensation. In this study, we address the question of whether the CS influences plantar tactile sensation. 32 non cold sensation (Non-CS) and 31 cold sensation (CS) young females have participated in this research. A tactile sensation test was conducted at five plantar points (first and fifth toes, first and fifth metatarsal heads, and heel). Experimental results showed that although there was no significant difference at the first and fifth toes as well as the first metatarsal head and heel, the sensation threshold at the fifth metatarsal head for CS was lower than the Non-CS (21.61 ± 8.10 μm, 27.42 ± 11.02 μm respectively, p < 0.05). It was concluded that plantar tactile sensation for young females with cold sensation was more sensitive compared to healthy subjects.

“…The author also observed leaning on stimulation site and velocity and a dissimilarity in the maximum level between normal patients and patients with an early detection of nerve damage. [19] In this study, author try to assess patients with diabetic peripheral neuropathy using vibrations generated from a mobile phone. Total 61 patients were tested with three different techniques the first is using 10 g Semmes Weinstein, second is tuning fork, and the third is mobile phone generated vibration.…”

Diabetic Peripheral Neuropathy (DPN) is a lifelong problem of Diabetes. The nerves that reach to the arms, legs, and feet become damaged due to high glucose level over a long period of time. It leads to loss of sensation, and sometimes pain in feet and hands. DPN increases the risk of foot ulcers and amputation. About 60% to 70% over entire humans with diabetes will ultimately generate Peripheral Neuropathy. The present study proposes different methods for detection of DPN like Touch sensation test, Pressure sensation Test, Vibration sensation test. Currently, DPN diagnosed by using three different instruments. The first is 10 g SWM (Semmes Weinstein Monofilament), second is Tuning fork, third is Biothesiometer. One more method is also used that is Nerve conduction (NC) study, which is time consuming and cost is high. Different methods have some limitation like 10 g SWM have limitations like fabricating fault and atmospheric effect. The second instrument Tuning fork has limitation like method variation means physician to physician result was varied to detect DPN. Last instrument, Biothesiometer is more expensive instrument and required a highly skilled physician. Vibration is a very important parameter to detect DPN. On the basis of vibration mechanism, level of DPN can also be identified. To overcome above limitations, a reliable, portable, easiest and valid tool is required to detect DPN.

The purpose of this study is to examine the variability in sensory test of tactile results using Semmes-Weinstein monofilament (SWM). At present, several methods for measuring the tactile sensitivity are clinically used in diabetic peripheral neuropathy screening. One of these methods is a touch test that uses a device with nylon SWMs, i.e., SWMs embedded in a plastic handle. A small pushing force is applied at the handle to bow the filaments. Because of its ease and simplicity, the SWM test is conducted at the patient's bedside in a hospital. However, previous studies have reported some problems with this test. Studies have shown variations in the measured data, and it is uncertain whether these variations are caused by mechanical properties of the nylon fiber or by the motion of the operator's hands. We carried out two experiments to examine the effect of (1) the variability caused by the human operator conducting the SWM test on the test results and (2) the number of compressions of the SWM on the test results. In experiment 1, we measured the velocity of the operator's hand motion and the buckling force of the SWMs. The results showed variability in the hand motion of the operator conducting the SWM tests. In experiment 2, we measured the buckling force of the SWMs under a controlled velocity. We compared the buckling force of the SWMs through a number of trials. These results showed that the buckling force gradually decreases as the number of test cycles increase. In conclusion, we find that the accuracy of the SWM tests is a factor of the number of test cycles. Additionally, manual training for standardizing skills of medical staff members needs to be developed. Furthermore, the characteristics of the SWMs deteriorated over time. In future work, we aimto find a solution to minimize the variability in the SWM test results and develop a new testing system that uses tactile sensibility for diabetic peripheral neuropathy screening.
