Prosthetics Orthotics Design: KAFO_orthosis
Structural design loads, socket interface pressures, alignment tolerances, and component specifications for prosthetic limbs and orthotic devices. Covers transtibial (below-knee) and transfemoral (above-knee) prostheses, KAFO/AFO orthotics, and upper-limb prostheses. ISO 10328 cyclic load levels P3/P4/P5/P6, K-level activity classifications K0-K4, peak ground reaction forces, socket interface pressures by tissue type, and alignment tolerances. Per ISO 10328:2016, ISO 22523:2006, Frossard mechanical loading studies, CMS K-level definitions.
