For a person suffering from rheumatism, stroke or for other reasons has weakened hand muscles, the need for support or artificial strength is great. However, external strength can result in the passivity of the muscles, which leads to a weakened and thus sicker patient. A dependence on the product is created and confidence in one’s own strength disappears along with actual power. By combining exercise with support the patient can be strengthened while artificial strength helps the person cope with what can otherwise restrict normal life.
