What this research studies

You would be invited to help design and try a new socket and harness called the K‑Socket‑Harness (KSH) built from textile and frame parts inspired by athletic shoe technology. The team will first refine the design for broader use and manufacturability, then work with a small group of experienced Veterans with different residual limb lengths to get hands‑on feedback and make changes. After revisions, a larger group will compare the improved KSH to each person’s current prosthesis through everyday and structured activities to look for differences in comfort and function. The project uses a participatory action design approach so your input will directly shape the device.

Who could benefit from this research

Good fit: Ideal candidates are adults—especially Veterans—with transradial (below‑elbow) amputations who currently use or have experience using a prosthetic arm and can attend in‑person visits.

Not a fit: People with above‑elbow or shoulder‑level amputations, or those who do not use prosthetic limbs, are unlikely to benefit from this specific socket design.

Why it matters

Potential benefit: If successful, the KSH could increase socket comfort, encourage longer prosthesis wear, and improve arm and hand function during daily activities.

How similar studies have performed: Early preliminary tests showed promising results, but this specific textile‑based, variable‑compliance socket approach is relatively new and still being validated.
