Not enough patients (difficulty in recruiting according to the inclusion criteria)

At the early stage of the amputation, the residual limb presents post-surgical fluctuations related to post-operative phase, which would need a frequent prosthetic adjustment. In most cases, the volume of residual limb is constant from 12 to 18 months after surgery. However, some daily fluctuations could appear due to an underlying vascular disease for example, which could be painful and impact the quality of life with a constant need of prosthetics adjustment. The goal of this study is to assess the effectiveness of a system-adjusted fitting in comparison with a standard fitting.

With the " multiple N-of-1 trial " study type, pain, quality of life, functional effects and the patient satisfaction with assistive technology will be assessed for four weeks.
