What this trial studies

This clinical evaluation focuses on the effectiveness of the Caloprothese Connected Kit (CCK) in alleviating neuropathic and phantom limb pain in patients with trans-femoral or trans-tibial amputations. The study aims to assess the device's impact on pain levels, activity, and quality of life for individuals experiencing significant residual limb pain. Participants will be monitored for pain intensity and frequency, utilizing validated pain scales and assessments. The approach emphasizes early multimodal reassignment techniques to enhance rehabilitation outcomes for amputees.

Who should consider this trial

Good fit: Ideal candidates include adults with trans-femoral or trans-tibial amputations experiencing moderate to severe residual limb pain.

Not a fit: Patients with bilateral lower limb amputations or those with specific stump pathologies causing pain may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce neuropathic pain and improve the quality of life for amputees.

How similar studies have performed: While there is existing research on multimodal rehabilitation techniques for amputees, the specific use of the CCK device represents a novel approach that has not been extensively tested.
