A "Qi" feeling (a kind of comfortable sense) during and after acupuncture is one of the important determinants to decide quantity (trial number) of acupuncture stimulation. It has been reported that various autonomic responses were evoked when patients felt "Qi" and when acupuncture stimulation had significant effects on EEGs. However, quantitative relationships among acupuncture stimulation, E...

Today, electrical stimulation as a treatment method by creating muscle contraction by creating internal electrical stimulation is a method to reduce muscle pain. In addition, it is used to treat osteoarthritis. The aim of this study was to study, design and implement optimized hardware for electrical muscle stimulators to reduce pain and treat osteoarthritis. Here, the design of the optimal sys...

چکیده هدف: اعمال تحریکات الکتریکی با فرکانس پایین (low-frequency stimulation; lfs) اثر مهاری بر روند کیندلینگ دارد. مطالعات قبلی نشان داده که این اثرات مهاری تا حدی وابسته به فعالیت گیرنده های آدنوزینی است. در مطالعه حاضر نقش مسیر های مختلف موثر در تولید و حذف آدنوزین و نقش آنها در اعمال lfs مورد بررسی قرار گرفت. مواد و روش ها: حیوانات با تحریک الکتریکی (12 بار در روز) مسیر پرفورنت کیندل شدن...
