The EMS foot massager uses electrical impulses to stimulate deep muscle relaxation, mimicking physical exercise without movement. The device works by sending electrical charges through muscles, causing them to contract and relax naturally. It uses advanced technology with preset programs and automated functions to target specific benefits such as pain relief and improved blood circulation. Safety considerations include contraindications for certain individuals and the use of safety features in devices. The future outlook for EMS foot massagers involves innovation and precision, making personalized therapies more accessible.
