Function

Simplification of Movement: A single-axis hip joint simplifies the range of motion in the prosthetic limb, primarily allowing flexion and extension at the hip. While this is not as versatile as the natural human hip joint, it simplifies the design and operation of the prosthesis.

Stability: The single-axis hip joint provides stability during walking and other activities by allowing the prosthetic limb to move in a controlled manner in the sagittal plane (front to back). This stability is essential for maintaining balance and preventing falls.

Energy Efficiency: Prosthetic limbs with single-axis hip joints are often designed to be energy-efficient. They can store and release energy during gait, helping users conserve energy and walk more naturally.

Ease of Control: The simplified movement of a single-axis hip joint is easier for users to control compared to more complex joints. This can be especially important for individuals who are new to using prosthetic limbs.

Specific Applications: While single-axis hip joints are not as versatile as multi-axis joints, they are suitable for individuals with specific mobility needs, such as those who engage in activities that primarily involve forward and backward motion, like walking or running on flat surfaces.
