Like any transtibial prosthesis, a variety of methods could be used to capture the alignment, for monolimbs the accuracy of this alignment is all the more critical. One alignment method which purports to produce an á priori alignment which does not need to be adjusted through dynamic alignment is the vertical alignment axis VAA

Bench alignment of the transtibial prosthesis is done such that a slight external varus moment is generated during stance for stability. The results of this study suggested that this varus moment could be compromised by malalignments due to excessive adduction or medial translation of the socket.
In bench alignment of the transtibial prosthesis, the center of posterior brim of the socket is generally positioned 1.3 cm lateral to the center of the heel of the foot Berger and Fishman, 1997 . This bench alignment tends to create an external varus moment that results in decreased compression over the head of fibula and the superficial
defined as the alignment of the prosthesis. If an acceptable alignment of a lower-limb prosthesis cannot be achieved, the limb may be rejected by the wearer. Often the patient complains of discomfort or pain associated with the socket when in fact the alignment of the prosthesis is the root cause . On supply of a new prosthesis, the patient is
Purpose: The objectives of this study were to compare three á priori alignment methods and evaluate them based on initial gait quality and further alignment changes required to optimize gait. Á priori alignment is requisite for monolimbs, transtibial prostheses in which the socket and pylon are made from one piece of plastic, because monolimbs have no alignment adjustability.
What 2 socket and component settings are set in A/P bench alignment of a transtibial prosthesis? 1. line down center of lateral prosthesis should be slightly anterior to the ankle bolt, providing proper heel and toe levers 2. initial 5-10 deg of socket flexion.
Bench alignment. With these reference lines marked on the socket, the prosthetic leg can be assembled. All prosthetic components have a manufacturers recommendation for where the alignment reference line should pass through. By following these recommendations the prosthesis will have a safe starting position from which individual tuning can begin.
Transtibial Below Knee Manual Common Terms and Definitions 4 Pylon: A pole connecting the prosthetic socket to the foot. Alignment changes can be made at both ends of the pylon pole to fine-tune your gait. Residual Limb Stump : The remaining part of an amputated extremity.
Methods- 8 transtibial amputees, 8 students of prosthetics, and 2 prosthetists per amputee-student pair participated in the study. The student bench aligned 3 sets of endo components for the amputee according to each alignment method.

The alignment of transtibial prostheses is the relationship between the socket and foot in space, and it is tuned through three stages: bench alignment, static alignment, and dynamic alignment.1 4 A number of studies investi-gated the effects of prosthetic alignment changes on ampu-tees gait.5 The bench alignment is established based on
When a prosthesis is completed, but has yet to be fit on the user, the alignment is set to standard bench alignment. In this transtibial alignment setting, alignment screws are set to neutral positions. The prosthetist will perform both static and dynamic alignment observations, in order to adjust the prosthetic components.

aligning a transtibial prosthesis to an individual, but also for the development of a clinically objective and repeatable alignment protocol. In a broader scope, it is expected that the results can shed light on what is needed in future endeavors to continue improving prosthetic alignment techniques. This will allow individuals living with
For the correct TT and TF prosthetic alignment. The PROS.A. Assembly was designed for bench alignment of TT and TF modular lower limb prostheses. Up to 12 degrees of freedom have to be taken into account for the three-dimensional static alignment of these prosthesis.

Traditional bench alignment of transtibial prosthesis. Following bench alignment, the prosthesis is worn by the subject for assessment of static alignment in a standing position, using an adjustable endo-skeletal pylon to correct any possible malalignment Figure 3 . During dynamic alignment, any gait deviation such as excessive varus or
