Objective: This study was conducted to investigate the effect of high-intensity laser therapy(HILT), transcutaneous electrical nerve stimulation(TENS), and ultrasound(US) treatment on pain, grip strength, and hand function in patients who had undergone carpal tunnel syndrome surgery. Design: A randomized controlled trial. Methods: Thirty patients who had undergone carpal tunnel syndrome surgery were randomly assigned to receive either TENS combined with HILT, US combined with HILT, or only HILT as the control group. Treatments were applied around the surgical site, and pre- and post-treatment changes were evaluated. Pain was assessed using NPRS, hand symptoms using CTS-6 and BCTQ-SSS, grip strength with an electronic dynamometer, and hand function using BCTQ-FSS. Treatments were administered seven times over two weeks. Results: The pain and symptoms were significantly reduced(p<0.05) and grip strength and hand function were significantly increased(p<0.05) after treatment compared to before treatment for all subjects. Pain was significantly reduced(p<0.05) and grip strength was significantly increased(p<0.05) in the TESN+HILT group and US+HILT group compared to the Control group. Hand symptoms were significantly reduced(p<0.05) and hand function significantly increased(p<0.05) in the TENS+HILT group compared to the Control group. Conclusions: TENS combined with HILT was found to be more effective than US combined with HILT in reducing pain and symptoms and improving grip strength and hand function in patients following carpal tunnel syndrome surgery. These findings suggest that these treatment modalities can be beneficially applied in clinical practice.

Purpose: The purpose of this study was to investigate the effect of electrical stimulation (ES) on the wound closure rate, collagen deposition, and TGF-${\beta}$1 mRNA expression in skin wound of rat. Methods: Twenty male Sprague-Dawley rats (222~271 g) were randomly divided into ES (n=10) and control group (n=10). The ES group received a cathodal stimulation with 50 V at 100 pps for 30 minutes for 7 days, while the control group was not given electrical stimulation. The wound closure rate, collagen density and TGF-${\beta}$1 mRNA ratio were measured. Results: The mean wound closure rates in the ES and control groups were $83.79{\pm}16.35$% and $51.57{\pm}17.76$%, respectively (p<0.001). The collagen density in the ES and control groups were $46.67{\pm}10.68$% and $25.03{\pm}13.09$%, respectively (p<0.001). The TGF-${\beta}$1 mRNA ratio in the ES and control groups were $1.35{\pm}0.60$ and $0.63{\pm}0.30$, respectively at 6 hours post-wound (p<0.01) and $1.69{\pm}0.47$ and $1.32{\pm}0.28$, respectively, at 7 days post-wound (p<0.05). Conclusions: ES accelerated the wound closure rate of skin incision wounds and was accompanied by an increase in collagen deposition in the regenerating dermis. In addition, ES increased TGF-${\beta}$1 mRNA expression during wound healing process. These findings suggest that ES may activate TGF-${\beta}$1 expression, and may increase synthesis activities of fibroblasts in regenerating skin wounds in rats.

The purpose of this study was to compare the effects of high intensity, high frequency microcurrent electrical neuromuscular stimulation(MENS) of auricular and somatic acupuncture points and low intensity, low frequency microcurrent electrical neuromuscular stimulation(MENS) of auricular and somatic acupuncture points on experimental pressure threshold at the elbow according to the time. Fifty healthy adults, aged 19 to 26 years, were assigned randomly to one of five groups: 1) the high intensity, high frequency somatic group(n=10) received MENS to somatic acupuncture points, 2) the high intensity, high frequency auricular group(n=10) received MENS to auricular acupuncture points, 3) the low intensity, low frequency somatic group(n=10) received MENS to somatic acupuncture points, 4) the low intensity, low frequency somatic group(n=10) receive MENS to somatic acupuncture points, and 5) the placebo group(n=10) received placebo treatment and served as controls. Pressure threshold was measured before, after, 5 minutes, 10 minutes and 15 minutes. Pressure threshold has increased significantly(p<.05) in the high intensity, high frequency auricular group following treatment after 5 minutes, with no statistically significant differences in pressure threshold change scores among five groups, Only the high intensity, high frequency auricular group demonstrated statistically significant change score in pressure threshold following treatment after, 5 minutes, 10 minutes and 15 minutes after compared to the placebo group. The results indicated that MENS applied to the high intensity, high frequency auricular group increases pressure threshold.

The present study examined that in vivo/vitro test is investigated in normotensive sham-operated rats(NSR) and aldosterone-analogue deoxycorticosterone acetate (DOCA)-salt hypertensive rats(ADHR) and that the antiliypertensive effect was induced by silver spike point(SSP) electrical stimulation at meridian points(CV-3, -4, Ki-12, SP-6, LR-3, BL-25, -28, -32, -52), specifically, such as aldosterone in 24 hour urine analysis from normal volunteer. The heart weight, the tickness of vascular wall, collagen fiber and the systolic blood pressure were significantly increased in ADHR than that in NSR. The required time of PSS-induced resting tone and the phosphorylation of stress-activated protein kinase/c-Jun N-terminal protein kinase(SAPK/JNK) were significantly increased in ADHR than that in NSR. However, the Kv currents were significantly decreased in ADHR than that in NSR. The current of 1 Hz continue type of SSP electrical stimulation significantly decreased in excretion of urine aldosterone from normal volunteer. These results suggest that the development of aldosterone analogue-induced hypertension is associated with changed heart weight, content of collagen fiber, tickness of vascular wall, blood pressure, resting tone, voltage-dependent K+ current(Kv) and phosphorylation of SAPK/JNK, which directly affects blood pressure. Therefore the hypertension is a risk factor on cerebrovascular disease. Moreover, These results suggest that the SSP electrical stimulation, especially current of 1 Hz continue type, significantly regulates excretion of urine aldosterone from volunteer.

Purpose: Electrical stimulation is one of several treatments recommended for RA patients. Electrical stimulation of RA patients, reduces pain, or facilitates joint motion prior to exercises. However, there is still limited evidence on the efficacy of electrical stimulation and thus any conclusions drawn about this method remain controversial. Recently, Microcurrent Electrical Neuromuscular Stimulation (MENS) has received significant attention as a potential method of electrical stimulation. In this study, we investigated the effect of microcurrent treatment in rheumatoid arthritis rat. Methods: Subjects were allocated either to the control group or experimental group, which was subject to microcurrent stimulation. Interleukin-1 expression in the metatarsophlangeal joint and the oedema index in the ankle were used for classification and subsequent evaluation of pathology. Subjects were assessed at 1, 7 and 14 days after inducing rheumatoid arthritis through adjuvant injection. Thirty-six subjects, 18 in each group, were used in this study. Statistical analysis was performed by calculating the differences between the two groups and between each interval assessment. Categorical variables were compared between the two groups with the paired-T test. The one-way ANOVA test was performed to assess changes in ordinal variables. Results: Baseline characteristics were similar in both groups. Statistically significant differences were found between the two groups. The biological marker of pro-inflammatory cytokine and oedema index were decreased in response to this treatment. Conclusion: These data show that treatment of rheumatoid arthritis with a microcurrent stimulation device reduced the oedema index and pro-inflammatory cytokine IL-1.

Purpose: This study examined the effects of neuromuscular electrical stimulation (NMES) and horseback riding using a robotic device on the trunk muscle activity and gross motor function in children with spastic diplegia. Methods: Children with spastic diplegia were divided into two groups: an experimental group (NMES and horseback riding using a robotic device [n=10]) and a control group (placebo NMES and horseback riding using a robotic device [n=10]). Each group received general physical therapy and occupational therapy. Each intervention involved the administration of NMES for 15 minutes and horseback riding using robotic device therapy for 15 minutes three times a week for 4 weeks. The evaluation included both the rectus abdominis muscles (RA), external oblique muscles (EO), thoracic paraspinal muscles (TP), and lumbar paraspinal muscles (LP) activity and GMFM. Results: The RA, EO, TP, and LP muscle activity, GMFM C, D, and E were increased significantly in the experimental and control groups. A significant increase in both the TP muscle activity and GMFM D was observed in the experimental group compared to the control group. Conclusion: This study showed that horseback riding using a robotic device is an effective intervention for trunk muscle activity and GMFM in children with spastic diplegia. However, if NMES is added to the back muscles, it is possible to further increase the thoracic paraspinal muscle activity and standing ability.

This study was carried out to determine the influencing of electrical stimulation to cervicothoracic sympathetic ganglion(CTSG; stellate ganglion) u the sympathetic tone. For the purpose of this study. the stimulation was given to both the interferential current stimulation(ICS: AMF 100Hz) group consisting of 10 person(males 8, females 2) and the transcutaneous nerve electrical stimulation(TENS: 100 Hz) group of 10(males 7, females 3) in the right side of the trachea with probe electrodes. Then. the temperature changes on the surfaces of the forehead. cheek, neck and internal ear of cephalocervix, which is subject to the influence of the cervicothoracic sympathetic ganglion, and the palm. which is the end of the upper limbs. measured before. immediately alter. 10 minutes after and 20 minutes after experiment. The results are summarized as follows. 1. The emergence of remarkable Horner's symptoms which appear due to the changes of the tone of cervicothoracic sympathetic ganglion was not seen. However, in the interferential current stimulation group there were two felt the sense of warmth in the facial region and one person who felt it in the upper limbs, and in the transcutaneous nerve electrical stimulation group there was each one person who felt the sense of warmth in the facial region and in the upper limbs, respectively. Both groups have each one person who felt the sense of oppression in the eyelids. Three persons of the interferential current stimulation group and two persons of the transcutaneous nerve electrical stimulation group have the sense of hoarse voice or numbness in the neck. These are the symptoms that appeared during stimulation, so it is difficult for them to be considered as the direct effects of the changes of the tone of cervicothoracic sympathetic ganglion. 2. The t-test was performed to determine the significance between the right, which is the experimental side, and the left, which is the non-experimental side. Significance between the right, which is the experimental side, and the left, which is the non-experimental side. Significant changes were seen in the necks of the interferential current stimulation group and in the cheeks and internal ears of the transcutaneous nerve electrical stimulation immediately after experiment(P<.05). And the interferential current stimulation group showed a very high significance in the cheeks immediately after experiment and in the necks ten minutes after experiment(p<.01). Therefore, it could be seen that the electrical stimulation had an influencing on the changes of body temperature of the cephalocervix. 3. In both the interferential current stimulation group and the transcutaneous nerve electrical stimulation group, the forecheads, checks and necks of the cephalocervix in the experimental side(right) rather than the non-experimental side(left) had mostly a statistically significant rise in temperature immediately after experiment. The one-way ANOVA was carried out to determine the temperature change of on the surface of the body with the lapse of time; before, immediately after, ten minutes after and tewenty minutes after experiment. But no statistical significance was found from both the right and left sides.

The purpose of this study was to investigate the effects of functional electrical stimulation (FES) with mirror therapy on balance and gait ability in chronic stroke patients. Thirty-five subjects who met the inclusion criteria were randomly allocated into three groups: the functional electrical stimulation with mirror therapy group(FMT group, n=11), mirror therapy group(MT group, n=12), and control group (n=12). The exercises were conducted for 30 min per day, five, per week for four weeks. Balance and gait ability were examined at baseline and after 4 weeks of intervention. After training, the FMT group showed significant improvement in berg balance scale (BBS), center of pressure (COP) length, affected step length (ASL), Cadence and average gait speed (AGS) compared MT group and control group(p<0.05). This findings show that FES and MT convergence can be an effective intervention for stroke patients balance and gait ability. Continued development of convergence interventions for stroke patients with balance and gait ability in practice, are suggested.
