First, stimulate electro muscle. EMS is the use of electrical impulses to cause muscle contractions. After 5-6 weeks of EMS treatment, muscle mass will increase by about 1% and muscle function will improve by about 10-15%. Second, massage the neck. Electrical pulses of acupuncture-style stimulation help relieve neck pain, improve blood circulation in the neck and improve sleep quality. Third, relieve back pain. EMS delivers electrical pulses to the muscles around the area of back pain, which relaxes muscle, reduces pain, reduces inflammation, and reduces muscle spasms. Fourth, exercise muscles. EMS slimming machine works by stimulating the muscles that are being exercised to strengthen the contractions and make them stronger.
