What is prosthesis alignment?
Alignment of a prosthesis is defined as the position of the socket relative to the other prosthetic components of the limb. During dynamic alignment the prosthetist, using subjective judgment and feedback from the patient, aims to achieve the most suitable limb geometry for best function and comfort.
What are the causes of Transtibial gait deviations?
DOI:
| Gait Cycle Phase | Gait Deviation | Prosthetic Cause(s) |
|---|---|---|
| Midstance | Lateral trunk bending (MSt, occasionally swing) | Pain from the prosthetic socket |
| Preswing | Insufficient push-off (early heel off) | Foot is too far posterior, causing shortened anterior lever arm |
| Foot is too dorsiflexed | ||
| Delayed heel off |
What is static and dynamic alignment?
Static alignment gives us the opportunity to correct issues such as soft foot, gross misalignment and to bring the system to within specifications. Dynamic alignment is the condition of the machinery during sustained operation.
What is bench alignment for prosthetics?
Bench alignment, which is the assembly of the various components can be done without the aid of any special devices. The other two procedures require the aid of a device or devices if optimum placement of the components is to be achieved.

What is socket flexion?
Socket flexion/extension is named for the alignment it produces in the most distal residual joint. The prosthetist can align the socket in some “initial flexion” for an individual with short hip or knee flexors.
What causes excessive knee flexion?
Excessive knee flexion moment during loading response is caused by a foot that is set too far posteriorly, is too dorsiflexed, or has a heel that is too rigid. The transition during loading response should be smooth and controlled.
What is dynamic alignment in dance?
Dynamic alignment is defined as an ongoing process of neuromuscular postural responses occurring at an unconscious level, and can refer to the body in stance or in motion, in a variety of conditions.
