What is the minimum acceptable efficiency for cable and cable housing?

The minimum acceptable efficiency for cable and cable housing typically follows industry standards where a range of 70% is considered the baseline for performance. This efficiency essentially refers to the proportion of input force transmitted effectively through the cable system to achieve the desired movement or action of the prosthetic or orthotic device.

Achieving this level of efficiency is important because it ensures that any energy exerted by the user through the device translates into the intended mechanical output, thereby improving functionality and user experience. Cables and housing that operate at this minimum efficiency are more likely to provide the necessary responsiveness and reliability required in orthotic and prosthetic applications.

Higher efficiency ratings are indeed desirable and can lead to improved performance, but the 70% threshold is an industry-recognized minimum that ensures the system can operate effectively while accommodating factors such as wear, load, and friction.
