I just used the unit on my shoulder for about 5 minutes, for the first time.
Afterwards, I raised my arm up to the ceiling. I haven't been able to raise it any higher than just above straight out to the side,for years. I have no idea how one treatment could accomplish this, but, wow, I'm a believer.
The unit arrived on time and was packed well. I charged it and connected it as my doctor directed and increased the signal strength but was disappointed to learn it was very weak and did not work my muscles properly.
The TENS7000 is a very solid device. It works well and will provide a lot of relief for me. Well done 👍🏾.
