residual limbs, pain, adjustable socket
Brief summary
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.
Detailed description
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.
Interventions
OTHERSocket without Revofit system
All the tests are evaluate during one week with the classical type of fittings
OTHERSocket with Revofit system
All the tests are evaluate during one week with the adjustable type of fittings (that is to say with Revofit system)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain change assessment | four weeks | Assess the impact of the Revofit™ system adjusted-fitting on residual limb pain compared to a classic fitting with a daily Visual Analog Scale evaluation \[VAS : 0 to 10 which constitues the worst outcome\]. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Everyday comfort | four weeks | Quality of life assessed by daily number of adaptation of the prosthesis |
| Functional effects in twin task | Once a week during four weeks | A walking analysis by GAITrite once a week |
| Functional effects in simple task | Once a week during four weeks | A walking analysis by a six-minute walking distance test once a week |
| Patient satisfaction with assistive technology | Once a week during four weeks | Assessment of patient satisfaction by using Quebec User Evaluation of Satisfaction with assistive Technology \[QUEST\] survey |
