Abstract: Methods for treatment and prevention of disorders resulting from hypertension of neck and shoulder muscles, in particular hypertension of the scalenius muscles, comprise administering a training regime to a subject suffering from the disorders, whereby the training regime comprises manipulating an object while maintaining a pinch-grip force exerted by the fingers on the object below a given threshold value. The object preferably has a pressure sensor that generates a signal when the pinch-grip force exceeds the threshold value. The object may be a writing instrument whereby the training may comprise writing exercises.
