The purpose of the present study was to investigate the effectiveness of silver spike point (SSP) low frequency electrical stimulation on glomerular filtration rate (GFR), specifically, such as diuretic action in 24 hour urine and in plasma analysis from normal volunteer. The current of 1 Hz continue type (CT) of SSP low frequency electrical stimulation significantly decreased in plasma creatine from normal volunteer. However, the urine creatinine clearance (Ccr) was significantly increased by SSP low frequency electrical stimulation in normal volunteer. These results suggest that the SSP low frequency electrical stimulation, especially current of 1 Hz continue type, significantly regulates urine creatinine clearance and glomerular filtration rate from normal volunteer. Therefore, the SSP low frequency electrical stimulation is a good regulator through a diuretic action of hypertension.

Purpose : The goal of this study is to estimate the effect of SSP electrical stimulation applied to acupoints as conducted in oriental medicine on the swallowing function of patients with swallowing difficulties caused by stroke. Methods : Twenty-two hemiplegic stroke patients with swallowing difficulties were divided into an intervention-only group (Group I; n=11) and an intervention-SSP electrical stimulation group (Group II; n=11). Therapeutic intervention was performed on participants in the intervention-only group and the intervention-SSP electrical stimulation group, for 20 minutes per session, three times per week, for four weeks. In this study, SSP electrical stimulation to the acupoints (Cheondol, Yomchon, Budol, Pungji, and Sanyinjian) of stroke patients with swallowing difficulties was applied, and to investigate the effects of SSP electrical stimulation, Clinical dysphagia scale (CDS) and ultrasonography assessment was used to measure pre and post-intervention scores. Results : In the clinical dysphagia scale assessment, the post-intervention score for group II had significant enhancement unlike group I. In the ultrasonography assessment, the hyolaryngeal movement in group II showed significant increase in the swallowing function unlike group I. Conclusion : From the above results, significant effects came from SSP electrical stimulation of 3Hz, biphasic wave, continuous current when applied to the acupoints as conducted in oriental medicine to improve the swallowing function of stroke patients.

Purpose: This study was designed to compare the effects of transcutaneous electrical nerve stimulation (TENS) and silver spike point (SSP) therapy on current perception threshold (CPT) and mechanical pain threshold (MPT). Methods: Forty-five healthy adult male and female subjects were studied. Fourteen of them were males and twenty-one were females. Subject were randomly assigned to receive; (1) TENS (80/120 Hz alternating frequency), (2) SSP (3 Hz), or (3) no treatment (control group). Electric stimulation was applied over LI4 and LI11 on acupuncture points of the left forearm for 30 minutes. CPT and MPT were recorded before and after electrical stimulation. The data were analyzed using linear mixed models, with group treated as a between subject factor and time a within-subject factor. Results: At 30 minutes after cessation of electrical stimulation the CPT of C fibers and A${\delta}$fibers was reduced in the TENS group that of C fibers was reduced in the SSP group (p<0.05). After cessation of electrical stimulation, the MPT of C fibers and A${\delta}$fibers increased in the TENS group, and that of A${\delta}$fibers increased in the SSP group (p<0.05). Conclusion: After TENS and SSP stimulation, MPT of C fibers and A${\delta}$fibers were selectively increased. In particular, the TENS group showed increases in both C and A${\delta}$fibers, while the SSP group showed increases only in A${\delta}$fibers.

The present study examined that in vivo test is investigated in sham-operated(control group) and aldosterone-analogue deoxycorticosterone acetate (DOCA)-salt hypertensive animals(experimental group) and that the antihypertensive effect was induced by silver spike point(SSP) low frequency electrical stimulation at meridian points(CV-3, -4, Ki-12, SP-6, LR-3, BL-25, -28, -32, -52), specifically, such as diuretic action in 24 hour urine analysis from normal volunteer. The $Na^+$ and $Ca^{2+}$ ions were significantly increased in aldosterone-analogue DOCA-salt hypertensive rats than that in sham-operated rats. However, the $K^+$ ions were significantly decreased in aldosterone-analogue DOCA-salt hypertensive rats than that in sham-operated rats. The current of 1 Hz continue type of SSP low frequency electrical stimulation significantly increased in excretion of urine $Na^+$ and $K^+$ ions from normal volunteer. However, the excretion of $Ca^{2+}$ ion were significantly decreased by SSP electrical stimulation in volunteer. These results suggest that the development of aldosterone analogue-DOCA-salt hypertension is associated with changed $Na^+$, $K^+$ and $Ca^{2+}$ ions of urine. which directly affects blood pressure. Therefore, the hypertension is a risk factor on cardiovascular disease. Moreover, These results demonstrate that the SSP low frequency electrical stimulation, especially current of 1 Hz continue type, significantly regulates $Na^+$, $Ca^{2+}$ and $K^+$ ions from volunteer. Therefore, the SSP low frequency electrical stimulation is a good regulator through a diuretic action of aldosterone-induced hypertension.

The purpose of this study was to demonstrate the effects of silver spike point (SSP) low frequency electrical stimulation on plasma ${\beta}-endorphin$ activities measured by radio- immunoassay from normal volunteer and the effects of ${\beta}-endorphin$ on 5-hydroxytryptamine (5-HT, serotonin)-induced contraction investigated by isometric tension methode in rats. The current of 3 Hz continue type, but not 100 Hz continue type, of SSP low frequency electrical stimulation significantly increased in plasma ${\beta}-endorphin$ from normal volunteer. The endothelial cell-dependent 5-HT-induced contractions were inhibited by ${\beta}-endorphin$ $1{\mu}M$. These results suggest that the ${\beta}-endorphin$ regulates nociceptive-like substance, such as 5-HT, in part and that the SSP low frequency electrical stimulation, specifically current of low frequency of 3 Hz continue type, significantly increases plasma ${\beta}-endorphin$ from normal volunteer.

In human body, catecholamines, such as epinephrine and norepinephrine, can be increased anxiety, blood pressure and pain etc. The inhibitory effects of TENS, electroacupuncture and massage on the release of epinephrine, norepinephrine from sympathetic nerve endings has already been known. However, the effects of silver spike point stimulation on the catecholamines was not well understood. Therefore, the purpose of this study was to characterize the SSP-induced inhibitory effects of catecholamines. The following results were obtained. (1) The studies on urinary catecholamines released that the levels of epinephrine and norepinephrine of continue type SSP stimulation group were significantly lower than those in the control group in human in vivo. (2) The dose-response curves of epinephrine and norepinephrine in rat aortic smooth muscle strips were increased dose dependent manner respectively. However, the contractile response of norepinephrine in rat aortic smooth muscle strips were slightly differentiated. It is concluded that the SSP stimulation reflects to the inhibitory effects of epinephrine and norepinephrine in men. Especially, we believe that the amplitude-frequency modulation, such as continue type a)1d frequency modulation type, of SSP stimulation plays a role in regulating catecholamines.

The aim of this study was to demonstrate the effects of silver spike point (SSP) low frequency electrical stimulation on plasma vasoactive intestinal polypeptide (VIP) activities measured by radioimmunoassay from volunteer and the effects of VIP on pain substance-induced contraction investigated by isometric tension methode in animal. The current of 3 Hz continue type, but not 100 Hz continue type, of SSP low frequency electrical stimulation significantly increased in plasma VIP from normal volunteer. The pain substance, such as norepinephrine, serotonin, and prostaglandin $F2{\alpha}$, increased vascular smooth muscle contraction, respectively. These responses were inhibited by VIP applied cumulatively (1 nM - $1\;{\mu}M$), but not serotonin-induced contraction. In addition, serotonin, and prostaglandin $F2{\alpha}$ induced uterine smooth muscle contraction from rat. However, these responses were inhibited by VIP ($1\;{\mu}M$), only serotonin-induced contraction. These results suggest that the VIP regulates pain substance in part and that the SSP low frequency electrical stimulation, specifically current of 3 Hz continue type, significantly increases plasma VIP from volunteer.

This study examined how the application of silver spike point (SSP) and acupuncture-like transcutaneous electrical nerve stimulation (A-TENS) on acupoints affects blood flow and pain threshold, using laser Doppler blood fluxes and the Commander algometer. Our study included 32 healthy men and women who were randomly divided into the SSP group (n=18) and the A-TENS group (n=14). The pain threshold and blood flow were measured at the Neiguan (PC6) of the Jueyin Pericardium Meridian of the hand. SSP was performed with a 2.8cm electrode at a fixed frequency of 3 Hz for 15 minutes. The change in blood flow and pain threshold after the intervention significantly differed between the two groups (p<0.05). We found that the application of SSP and A-TENS on an acupoint altered their blood flow and pressure pain threshold, with SSP resulting in significantly greater change than A-TENS. Based on these results, the convergence of acupoint and electrical stimulation therapy can be usefully applied as a method for various patients. Continued development of convergence interventions is necessary.

The purpose of this study was to determine a more effective method for shoulder pain reduction. Forty-five normal subjects were randomly assigned to one of 3 groups a control group, an acupuncture-like transcutaneous electrical nerve stimulation(ALTENS) group, and a silver spike point(SSP) group. Each person in the ALTENS and SSP groups was measured for pressure pain threshold before and after a 20 minute treatment. The control group was also checked for pressure pain threshold before and after a 20 minute period but no "treatment" was given. The major findings were as follows ; 1)The ALTENS and SSP groups showed significant differences before and after treatment but the control group showed no significant difference. 2)When the three groups were compared, the only significant difference was between the SSP group and the control group. As mentioned above, it may be concluded that both ALTENS and SSP therapy were effective in reducing shoulder pain when measured directly after treatment. However, SSP did not show any superior effect. Further study should be done to determine the effective the maintained pain reduction with post-treatment time lapse.
