This study was conducted to assess the effect of transcutaneous electrical nerve stimulation(TENS) and interferential current(IFC) in the patients with myofascial pain syndrome(MPS) on upper trapezius. Twenty patients with MPS on upper trapezius was assigned randomly to TENS group(n=10), IFC group(n=10). In TENS group, TENS was applied to the trigger point. In IFC group, IFC was applied to the trigger point. Duration of treatment was 2 weeks. Effects were assessed before treatment, post treatment by visual analogue scale(VAS), and pain rating score(PRS). Significant change of VAS was noticed in TENS group and IFC group. Significant change of PRS was noticed in TENS group and IFC group. IFC groups were significantly higher than TENS group that of the VAS and PRS. These result showed that IFC is effective treatment method for pain control in patients with MPS.

Background: The purpose of this study is to have examined the influence on the blood circulation by comparing the differences between stimulating the sympathetic ganglion and the muscle group among the stimulation variables in interferential current stimulation. Method: The object of the study is the twenties(M=8, F=12), who are in great condition and have no pathological report for the blood circulation influence. The intensity of the inferential current stimulation is the medium degree, 100 bps constant current, which is the comfort and degree to confirm the muscle contraction. The areas stimulated are the stellate ganglion area in the seventh cervical vertebrae and the forearm muscle area. Results: We have made sure that there is no change in blood pressure and pulse and that the change in the skin temperature occurred highly. Conclusion: In considering the change of the blood circulation in case of stimulation area by the inferential current stimulation, we have seen that stimulating the sympathetic ganglion area is more effective than stimulating muscle area directly.

TCD(transcranial doppler, TCD) units is a equipment that measure a blood flow velocity in the middle cerebral artery(MCA), anterior cerebral artery(ACA), posterior cerebral artery(PCA), and vertebral artery(VA). The aim of this study was to determine the influence on cerebral blood flow velocity according to different stimulation frequency of interferential currents. 50 patients who has a cervical pain were participated in this study and randomly divided into one of the three experimental, placebo, and control group: (1)IFS 1; $10{\sim}30Hz$ was applied, (2)IFS 2; $30{\sim}50Hz$ was applied, (3)IFS 3; $50{\sim}100Hz$ was applied, (4)placebo; suction only applied, and (5)control; neither suction nor interferential stimulation applied. In the IFS groups, interferential stimulations were applied through four suction electrodes application from the 5th cervical to the 1st thoracic level. The results were as follow; 1. MCA was statistically significant with IFS 1, IFS 2, IFS 3, and Placebo group(p<0.05), But there was no statistical significance between IFS 1 and IFS 3 group(p>0.05). 2. ACA was statistically significant with IFS 1, IFS 2, and IFS 3 group(p<0.05). And IFS 1 was more statistical significance than IFS 3 group on ACA(p<0.05). 3. PCA was statistically significant with IFS 1, IFS 2, and IFS 3 group(p<0.05). And IFS 1 was more statistical significance than IFS 3 group on PCA(p<0.05). 4. VA was statistically significant with IFS 1, IFS 2, and IFS 3 group(p<0.05). And IFS 1 was more statistical significance than IFS 3 group on VA(p<0.05).

PURPOSE: This study examined the efficacy of an interferential current (IFC) treatment on the improvement of pain, disability, and quality of life in stroke patients with lumbago. METHODS: A double-blind, randomized clinical trial was conducted on 40 stroke patients with lumbago. The patients were allocated randomly into two groups: the IFC treatment group (n= 20) and the placebo treatment group (n= 20). The IFC group received 30 minutes of IFC treatment on the lumbar region, while the placebo group received IFC treatment but without real electrical stimulation. The intervention was administered five days a week for four weeks. The primary outcomes of pain intensity were measured using a visual analogue scale. The secondary measurements included the Barthel Index, Oswestry Disability Index (ODI), and health-related quality of life (HRQoL). RESULTS: The measurements were conducted before and after the two-week intervention period. Compared to the placebo treatment group, the IFC treatment group showed significantly greater improvement in the pain intensity (p<.05), ODI (p<.05), and SF-36 (p<.05) at the end of the intervention. No significant differences in the Barthel Index were found between the two groups. CONCLUSION: These findings show that an IFC treatment can improve pain, functional ability, and quality of life, highlighting the benefits of somatosensory stimulation from IFC in stroke patients with lumbago.

Purpose : The purpose of study was to better understand the effects of Interferential Current (IFC) and Ultrasound on the ROM and pain in patients with chronic back muscle pain. Methods : Twenty patients with chronic back pain were randomly assigned to IFC stimulation groups and Ultrasound stimulation groups. Both groups used the same method for 20 minutes each session, three times a week for 4 weeks at the same time point and with the same amount of treatment. Measurement items are visual analogue scale (VAS) and range of motion (ROM). Results : This study showed that the IFC stimulation group and the ultrasound stimulation group demonstrated significant improvement in ROM increase and pain reduction. Both groups showed a significant reduction in VAS; however, the ultrasound stimulation group decreased more than ultrasound stimulation group. And, both groups showed a significant increase in ROM. The ultrasound stimulation group increased significantly more than the IFC stimulation group in ROM of flexion and extension. The IFC stimulation group increased significantly more than the ultrasound stimulation group in ROM of lateral flexion. Conclusion : Pain relief was more effective in the ultrasound group. The ultrasound showed a more significant effect than IFC in ROM of flexion and extension. The IFC showed a more significant effect than ultrasound in ROM lateral flexion. The results of this study suggest that the treatment effects are different on patients with chronic back pain, according to treatment methods.
