This study was designed to investigate the feasibility of utilizing an adaptation for selective elicitation of tactile sensations by means of transcutaneous electrical stimulation. We conducted the first experiment to investigate how the stimulation frequency affected the adaptation. Twenty healthy subjects participated in the second experiment to confirm our proposal that the perception intensity of the low-frequency vibration can be enhanced after a high-frequency adaptation, and vice versa. It was found that (1) a low-frequency stimulation did not adapt the nerve afferents responsible for the high-frequency vibration, (2) a high-frequency stimulation affected the nerve afferents responsible for the low-frequency vibration, but adapted to the pressure sensation more intensely, and (3) more than 62% of the subjects reported a more clear selective sensation after the adaptation had lessened or depressed the unwanted sensation. The observations showed that adaptation of the nerve afferent could be utilized for selective elicitation of tactile sensations.

Background: The purpose of this study was influence of change of electrical stimulation time on body regions affects on electrical current threshold. Methods: The present study is to examine the effect of silver spike point (SSP) electrical stimulation (1Hz), transcutaneous electrical nerve stimulation (TENS, 100Hz), and interferential current therapy (ICT, 50Hz) from the low back and scapulodorsal and knee joint regions on stimulation-induced current thresholds from the elderly (over sixty) people (male:72, female:91) in senior welfare center. Result: The low back region, but not scapulodorsal and knee joint region, significantly increased the TENS and ICT, but not SSP, electrical stimulation, significantly increased the time-dependent current thresholds in elderly patients. Conclusion: Therefore, these results, in part, suggest that the TENS and ICT were shown to be a more adaptable method of stimulation, and that needed of the development of senile specialized physical therapy and the utilization of senior leisure facilities such as senior welfare center the others.

Tinnitus is a prevalent disorder that has no cure currently. Within the last two decades, neuroscientific research has facilitated a better understanding of the pathophysiological mechanisms that underlie the generation and maintenance of tinnitus, and the brain and nerves have been identified as potential targets for its treatment using non-invasive brain stimulation methods. This article reviews studies on tinnitus patients using transcranial magnetic stimulation, transcranial electrical stimulation, such as transcranial direct current stimulation, alternating current stimulation, transcranial random noise stimulation as well as transcutaneous vagus nerve stimulation and bimodal combined auditory and somatosensory stimulation. Although none of these approaches has demonstrated effects that would justify its use in routine treatment, the studies have provided important insights into tinnitus pathophysiology. Moreover bimodal stimulation, which has only been developed recently, has shown promising results in pilot trials and is a candidate for further development into a valuable treatment procedure.

The purpose of this study is to evaluate the effectiveness of traditional Korean medicine treatment of cervical vertigo. Three patients were diagnosed as cervical vertigo with correlating symptoms of imbalance and dizziness with neck pain. The diagnosis of cervical vertigo is also dependent on excluding other vestibular disorders on the basis of history, examination, and vestibular function tests. They were treated by acupuncture, transcutaneous electrical nerve stimulation therapy and low-intensity pulsed ultrasound at acupoints and sympathetic ganglion chain of their cervical and upper thoracic region. The evaluation of clinical outcome was done by numeric rating scale (NRS), dizziness handicap inventory (DHI) and neck disability index (NDI), EuroQol-five dimensions questionnaire (EQ-5D) index. After the treatment, the value of their NRS, NDI, DHI was significantly decreased and their EQ-5D index was significantly increased. The traditional Korean medicine treatment at cervical and upper thoracic region could be an effective way to treat cervical vertigo.

An A-B-A-C single subject research design was used to assess the effectiveness of transcutaneous electrical nerve stimulation(TENS) and inhibitive techniques on spasticity in a 10-year-old girl with cerebral palsy. Stimulation electrodes were placed over the sural nerve of the right leg. The standard method of cutaneous stimulation, TENS with impulse frequency of 100 Hz, was applied. Inhibitive techniques including stretch, antagonist contraction, and weight bearing were used. The tonus of the leg muscle was measured by means of a surface-EMG biofeedback unit. Visual analysis of data indicate that the child showed clinically significant reduction of spasticity in passive ankle movement following 30 minutes of TENS and inhibitive techniques application, respectively. The effect of TENS on spasticity inhibition was similar to that of inhibitive techniques. This result suggests that for this child with cerebral palsy, the application of TENS to the sural nerve may induce short-term post-stimulation inhibitory effects on the spasticity of cerebral palsy. Replication of this study with a more complex single-subject design involving more subjects is recommended to confirm this result.

The purpose of this study is to investigate the relationship between effects of TENS (Transcutaneous Electrical Nerve Stimulation) and IFC(Interferrential Current Therapy) to the change of body surface temperature. Cases are 22 normal persons and 22 patients with low back pain. Digital Infrared Thermal Imaging system was used for the detection of body surface temperature. 50Hz in frequency and 25-35mA in intensity were applied to TENS and IFC, 15 and 10 minutes on each. The results were follows ; 1. TENS and IFC has on effect of decreasing surface temperature, which would be from cardiovascular factors. (P<0.001) 2. The influence of IFC to the body surface temperature is greater than TENS, and it seems to be vasoconstriction of sympathetic activity. 3. There were no significant differences of body surface temperature between the two groups before and after electrical stimulation.

The purpose of this study is compare the effects of two therapeutic processes-i) conservative Myofacial Release Technique along and ii) Transcutaneous Electrical Nerve stimuliation alone - on the increase in the range of motion(ROM) and on the decrease in patient's pain with chronic Neck pain. The subjects of the study were student with choronic neck pain in Daegu health university. Half of them (10) took conservative Myofacial Release Technique along and the others (10) took Transcutaneous Electrical Nerve stimuliation alone. I used 3D Motion analysis. The range of motion (ROM) in six areas-flexion, extension, left lateral flexion, right lateral flexion, left rotation, right rotation-to check the effectiveness of the two combinations of methods, measured pain with visual analogue scale (VAS) to see the effect on pain reduce. Assement was conducted to the groups before the treatment began and affer the four weeks treatment ended. This study shows that both groups demonstrated significant improvement in ROM increase and pain reduction. Flexion ROM increases were significant in MFR and TENS after treatment 2 weeks and 4 weeks. Extension ROM increases were significant in MFR and TENS after treatment 2 weeks. Right rotation ROM was no significant differences were found in MFR and TENS after treatment all weeks. Right lateral flexion ROM increases were significant in MFR and TENS after treatment 3 weeks. Left lateral flexion ROM increases were significant in MFR and TENS after treatment 1 weeks. But the others no significant differences were in MFR group and TENS group during 4 weeks.

PURPOSE: This study examined the effect of high-frequency transcutaneous electrical nerve stimulation (TENS) and San-Yin-Jiao (SP6) acupressure on primary dysmenorrhea. Furthermore, the difference in effectiveness between the two methods were compared. METHODS: Twenty-six students participated in this study, and were randomly assigned to a high-frequency TENS group(experimental 1, n=9), a San-Yin-Jiao (SP6) acupressure group(experimental 2, n=9), and no treatment group(control, n=8). They were assessed and treated on the first day of their menstruation. The TENS protocol included applying 20 minutes of stimulation with a frequency of 100Hz, $100{\mu}sec$ pulse width. Four electrodes were placed on the skin 3 cm from midline at T12-L1 and S2-3 paravertebral muscles. San-Yin-Jiao (SP6) acupressure should be applied with the thumb for 10 minutes(8 seconds pressure and 2 seconds rest) on the SP6 acupoint. This procedure should be repeated for the other foot. Dysmenorrheal pain measured two pain assessment tools (VAS, DPT) pre-treatment; immediate post-treatment; 30minutes, 1, 2hours; and 3, 4, 5, 6, 24 hours after the VAS test were added. RESULTS: The results showed significant differences in pain assessments (VAS, DPT) after treatment for subjects of experimental group1 (p<.05) and experimental group2 (p<.05), whereas the between-group comparison found no statistically significant differences. CONCLUSION: This result supports the idea that using two methods could be effective in pain reduction among students who suffered from primary dysmenorrhea.

A 30-year-old woman with Grade III hemorrhoid complained of excruciating pain that continued for several hours, especially with defecation. She was not able to frequent the clinic due to COVID-19 shutdowns, therefore additional treatment using acupoint electrical stimulation (AES) was self-administered. She administered AES bilaterally on BL57 and LR10 for fifteen minutes before each defecation as a preconditioning treatment. She assessed her pain using a Numerical Rating Scale (NRS) during defecation, and 3 hours later. The patient initially complained of pain rating 9 on the NRS. After the first session of AES, the pain dropped to 5. On one-month follow-up, the pain was at 3 and the patient was able to terminate all treatment. Self-administered AES preconditioning at BL57 and LR10 can be used to reduce extreme cases of hemorrhoid pain.
