Dr. Ho’s TENS device for muscular stimulation is a good value and assists in the rehabilitation of muscle stiffness and soreness. I have used this device in treating high school athletes in treatment of minor muscular strains and soreness.
I've had my first unit over a year and was happy with it. My son-in-law was visiting and tried it. He also was excited that it reduced his backache so I got fir his Christmas gift.
