In experiments on healthy children as well as on children with inborn and postamputation stumps of the forearm, studies have been made of the relationship between the level of tactile sensitivity in the skin of the forearm and the level of its muscular motor activity; these studies were performed using focused ultrasound in children at the age of 7, 10 and 14 years. It was found that with the increase in motor activity of the forearm, irrespectively of the age, tactile thresholds decrease. The success of prosthetic appliance depends on the ratio between skin tactile sensitivity and motor activity of the forearm. The lowest thresholds were found in 10-year children and in a zone innervated by the median skin nerve of the forearm.

The article presents the results of formation of the skin-muscular canal in 49 patients (60 operations) for handling prostheses with external energy sources. Helpless patients after the surgical treatment and prosthesing could fulfil actions for selfservice and a number of labor movements.
