That depends.
A little. Or a lot.
Fact: some therapeutic products on the market especially portable ones are very simple in structure and technology. Only little engineering is involved in inventing and making these devices. These products can nevertheless bring some low level of therapeutic effects, but to a very limited extent to our body. These low tier therapeutic products, unfortunately, tend to drag down the reputation of the whole therapeutic device market. Many customers regard the overall therapeutic device field as a low-in-technology industry. But that is not true.
On the other hand, there are companies and engineering teams that have been dedicated and aiming at building high tier, higher effect, sophisticated therapeutic products, and continue to do so. They continue to embed newest study, new materials and new technologies into their devices. The therapeutic effects from these devices are more substantial and because these devices are results/effects based.
Regardless of the appearance, complicated or simple, it is the inner structure and engineering that is important. To build a high tier therapeutic device is a lot of effort. First of all is the innovation: constant innovation is key to maintaining a higher level device line. Secondly it is the materialization of the ideas. This is the step that a lot of engineering barriers will be faced for a lot of device makers.
