Pre-prosthetic training for upper-extremity amputations (the golden window) is typically initiated how long after amputation?

• A. One week after amputation
• B. Two weeks after amputation
• C. Four weeks after amputation
• D. Eight weeks after amputation

Answer: (C)

The timing targets a period when the residual limb has stabilized enough for effective shaping and when the patient is ready to begin functional training. About four weeks after amputation is when edema has typically decreased, the incision has healed sufficiently, and the soft tissue can be molded for a socket. This window also takes advantage of ongoing neuroplasticity, making it easier for the patient to learn and integrate prosthetic control. Starting earlier can interfere with healing and limb shaping, while waiting longer reduces the benefits of early motor learning and adaptation. So, initiating pre-prosthetic training around four weeks post-op is the most conducive timing.
