The PROTAMINE project relies on the direct measurements of the forces and moments applied on the three axes of the residuum of individuals with limb loss.
The unique way to assess kinetic parameters was made possible by putting together a wearable kinetic system including a transducer measuring the load connected to some recording device (i.e., laptop, data logger).
The transducer was fitted between the prosthetic knee and the residuum (i.e., socket, fixation). The load can be assessed during an unlimited number of steps while performing various activities without being tethered by any connection with an external device.
Some experiments were also conducted during walking in a gait laboratory including forces plates and three-dimensional motion analysis systems.
