With the Harmony® system, increased negative pressure between the prosthesis socket and liner creates an optimum connection between the prosthesis and residual limb.


Proprioception is enhanced and strain on the residual limb is reduced. In addition, increasing the vacuum reduces the daily volume fluctuations of the residual limb. This effective system to connect a prosthesis has been available to transtibial amputees since 2001 in the form of the mechanical Harmony® pumps (e.g. P2 or HD). Their effectiveness has already been proven by several studies.
