I haven't tried either of those things and frankly I don't think it's likely that either would be effective, at least based on the explanations I've seen for them. They seem to be based on fixing problems (e.g. misalignment of bones and nerves or who knows what) that I don't believe have a basis in objective reality. On the other hand if people get relief from them I can't argue with it -- you can only go with what people report. As the old saying goes: believing is seeing.
