The goal of this observational study is to investigate the effectiveness of NMPKs versus MPKs in persons with an LLA in the standard healthcare system in the Netherlands taking all levels of the ICF model into account. Our main aim is to assess the effect of MPK use compared to NMPK use on walking distance, as this is one of the most used outcome variables in literature and thus enables comparison with previous studies. Our secondary aim is to investigate the effect of NMPKs versus MPKs on all ICF-levels: body structures and function, activities and participation. Participants will be seen four times in a year. During these measurement moments they will: * Perform two physical tests * Fill out a set of questionnaires * Wear an activity tracker for one week
