Study of an ankle prosthesis for children: adaptation of ISO 10328 and experimental tests

Object of the present study is an ankle prosthesis for transtibial amputees, designed for children. Standards for prostheses compliance available in literature are all related to adults, while very few studies are present for children. In the first part of the paper a discussion on the modification of the standard in terms of loads and distances is presented, to adapt the available data to the test case, a boy of 12 years and 45 kg. In the second part, experimental results are shown, considering four different types of tests: static proof and ultimate tests, fatigue tests and static torsion tests. Results were positive for the designed and tested ankle prosthesis
