Purpose: This study was designed to evaluate the effect of TENS on pain and pulmonary function of post-lobectomy patients with lung cancer. Methods: The study data collection was done from February 4, 2008 to February 7, 2009. The subjects were assigned at random to the experimental group and control group with 20 subjects in each group. The experimental group was measured for pain and pulmonary function after surgery and then again after applying TENS 100 Hz frequency and 40 mA output for 20 minutes. The control group was measured the same as the experimental group except applying sham TENS. Results: The pain score of the experimental group which had TENS applied revealed that there were more significant reductions than the control group which had sham TENS applied. There was no significant difference with the number of times of receiving analgesics between the experimental and control group. The effect of TENS on pulmonary function was significantly different between the experimental group and the control group on VC 2 hours after surgery. There was no significant difference between FVC and FEV1. Conclusion: The findings of the study indicate that the TENS is effective in easing the pain of patients after a lobectomy.

The purpose of this study was to compare acupuncture-like transcutaneous electrical nerve stimulation(ALTENS) with conventional transcutaneous electrical nerve stimulation(C-TENS) for crossover effect in healthy subjects. Forty subjects recieved ALTENS(20 persons), C-TENS(20 persons) to one upper extremity. Each technic was applied to the motor point of the wrist extensor muscle group for twenty-minutes. With the subject placed in supine the technics were applied at 80 Hz, 2-10 mA(ALTENS) and 10 Hz, 4-12 mA(C-TENS). Results revealed: (1) a significant difference between the pretreatment and posttreatment in each group(p<.05) (2) no significant difference between ALTENS and C-TENS(p>.05). In conclusion, there was no difference between ALTENS and C-TENS for crossover effect.

The purpose of this study was to determine the effect of transcutaneous electrical nerve stimulation(TENS) on the alteration of pressure pain threshold of myofascial trigger points. We used fifty nine patients with upper trapezius mayofascial pain syndrome. Participants classified according to each group in conventional TENS(high rate, low intensity) and acupuncture like TENS(low rate, high intensity). The test was measured continuously pre test, post-test by algometer. The following results were obtained; 1. Pressure pain threshold were significantly increased in all groups(p<.001). 2. In comparison between groups, pressure pain threshold were not significantly differenced. These results lead us to the conclusion that each method by TENS were significantly increased pressure pain threshold of upper trapezius trigger points. Therefore, a further direction of this study will be to provide more evidence that TENS method have an effect on pressure pain threshold of myofascial trigger points.

The purpose of this study were to examine the effect of high intensity, low frequency transcutaneous electrical nerve stimulation at auricular acupuncture points on experimental pain threshold measured at the wrist and to determine the changes in effect over time. Forty-two healthy adult men and women were assigned randomly to one of three treatment groups. Group 1(n=15) received TENS to appropriate auricular points for wrist, Group 2(n=12) received TENS to wrist, and Group 3(n=15) received no TENS. We measured experimental pain threshold at the wrist after an electrical stimulus during one pre-treatment and three post-treatment time periods. Group 1 and 2 showed stastically significant increase(p<0.05) in pain threshold after treatment whereas the Group 3 did not. Group 1 showed a significant increase in pain threshold than Group 2. These results suggest that high intensity, low frequency TENS applied to appropriate auricular acupuncture points can increase pain threshold.

The purpose of this study was to determine the effect of two different forms of transcutaneous electrical nerve stimulation(TENS) and one of microcurrent high voltage pulsed galvanic current(HVPC) on sympathetic tone in healthy subjects. Fourty subjects received TENS(20) and PVPC(30) during short time(20min). Left finger tip skin temperatures were measured at four interval for each treatment : 1) before treatment, 2) after 10 minutes treatment, 3)after 20 minutes treatment, and 4) after 10 minutes rest. The results were as follows. 1) TENS treatment group increased skin temperature after treatment 20 minutes, but HVPC treatment increased akin temperature after 10 minutes and recovered normal skin temperature after 10 minutes treatment. It means that short time(20min) electrical stimulation decreased sympathetic activities. 2) Sympathetic activities of TENS stimulation were influenced by age, but HVPC were not. 3) During 10 minutes, both treatment increased sympathetic activities, but HVPC treatment reversed sympathetic activity more rapidly than TENS. 4) The changes of skin temperature means by sex, males in TENS treatment group were higher than females, but HVPC were reverted.

Purpose: The purpose of this study was to investigate the change in sympathetic nervous system responses of healthy adult women with changes in stimulus intensity of high frequency transcutaneous electrical nerve stimulation. Methods: Twenty-four healthy subjects (women) received high frequency electrical stimulation of the forearm. The subjects were randomly assigned to one of two groups; a low intensity stimulation group (n=12) and a high intensity stimulation group (n=12). The electrode attachment was arranged on the forearm of the dominant arm and the electricity stimulus time was 20 minutes. Measured items included skin conductance, pulse rate, skin temperature, and respiration rate. Each was measured at 4 times. Results: Skin conductance and skin temperature showed significant group by time interactions, though there were no significant group and time effects. There were no significant differences according to time, group effect, and a group by time interaction in pulse and respiration rates. Conclusion: High frequency and high intensity electrical stimulation may be helpful for the improvement of sudomotor function through the activation of the sympathetic nervous system. Also, high frequency and low intensity electrical stimulation may be helpful for the reduction of sudomotor function via inhibition of the sympathetic nervous system.

Prostaglandins are generated through two isoforms of the enzyme cyclooxygenase, constitutively expressed cyclooxygenase(COX)-1 and COX-2, which is induced at sites of inflammation. Inhibition of COX-2 is desirable as this may avoid side effects seen with NSAIDs. We examined the effects of transcutaneous electrical nerve stimulation and cold therapy on the levels of muscle cycloooxygenase-2 mRNA in rats of carrageenan-induced inflammatory. The method of behavioral assessment were paw withdrawal latency(PWL) and tail flick test(TFT). The COX-2 mRNA levels were quantified by reverse transcription-polymerase chain reaction (RT-PCR). Following the transcutaneous electrical nerve stimulation and cold therapy, PWL and TFT were increased and COX-2 mRNA expression in gastrocnemius muscles were decreased. These results suggest that a transcutaneous electrical nerve stimulation and cold therapy were good therapy for a muscle pain.

Purpose：The purpose of this study is to investigate the effect of transcutaneous electrical stimulation on autonomic nervous system using heart rate variability analysis. Methods：31 subjects were evaluated with HRV before and after a single high-frequency TENS for 15minutes treatment. The standard deviation of all the normal RR-interval(SDNN) and lower frequency/high frequency ratio(LF/HF ratio) were recorded with TAS-9. Results：After single TENS treatment, autonomic adaptation as analyzed by SDNN was increased from $42.47\pm12.96$ to $4.43\pm16.76$(p>0.05) and autonomic balance as analyzed by LF/HF ratio was increased from $1.4\pm0.45$ to $1.45\pm0.41$(p>0.05). Conclusion：In this study, SDNN and LF/HF ratio changed in health young students as a result of single TENS treatment. But there is no significant difference between pre-treatment and post-treatment of SDNN and LF/HF ratio.

본 연구는 관절가동술 후 두 가지 유형의 전기치료 방법을 각각 적용하였을 때 유방암 환자의 어깨 가쪽돌림 가동범위와 통증에 미치는 효과를 알아보기 위해 실시하였다. 유방절제술을 시행한 유방암 환자 30명을 STMG (관절가동술+비침습적 무통증 신호 전기치료) 15명과 TENMG (관절가동술+경피신경전기자극) 15명으로 나누었다. 중재는 4주간 주 3회, 1회당 1시간씩 실시하였다. 측정은 어깨 가쪽 돌림 관절가동범위(Range of motion, ROM), 통증(Visual analog scale)을 측정하였다. 중재 전·후 두 군 모두 어깨 가쪽돌림 관절가동범위, 통증에서 유의한 차이가 있었다(p<.05). STMG는 어깨 가쪽 돌림 관절가동범위를 제외하고 TENMG보다 통증 감소에서 더욱 효과적이었다(p<.05). 유방암 절제술 환자의 통증을 경감시키기 위해서는 STMG이 TENMG보다 더욱 효과가 있다는 것을 확인할 수 있었다. 다양한 차이를 확인하기 위해 대조군을 더하고, 더 많은 대상자가 필요할 것으로 사료된다.
