The Vietnamese word "chạy điện" literally translates to "electric run" or "electric flow." In a medical context, it refers to "electrotherapy," which is a treatment method that uses electrical energy to help relieve pain, promote healing, or stimulate muscles.
In more advanced discussions, "chạy điện" can be associated with specific techniques or machines used in therapy, such as TENS (Transcutaneous Electrical Nerve Stimulation) units or other forms of electrical stimulation used in physiotherapy.
While "chạy điện" primarily refers to electrotherapy, it can also be used in a colloquial sense to describe situations involving electricity or electrical devices. However, this usage is less common.
