Description

TECHNICAL FIELD

[0001] The present disclosure relates, in general, to the technical field of biomechanics. More particularly, the present disclosure provides a self-balancing assembly for a prosthetic leg.BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Existing prosthetic practices have primarily focused on supplying artificial limbs as supplementary structures, offering completion rather than functional mobility. These prosthetics, mimicking the form of the natural limb, primarily address cosmetic concerns and maintain body balance but lack inherent movement capabilities. Users are compelled to undergo extensive training to emulate natural human movement, and the rigid design of these additional structures hinders flexibility. Consequently, these prosthetics often function more as cosmetic enhancements than facilitators of practical movement.

[0004] Moreover, such prosthetics prove more beneficial for individuals with one functional limb, as the additional structure aids in weight distribution when the amputated limb lacks a prosthetic. However, these solutions fall short of providing a comprehensive, adaptable, and user-friendly approach to mobility.

[0005] However, upon recognizing these limitations there exists a compelling need for the development of a cost-effective prosthetic limb that merges cosmetic considerations with dynamic movement capabilities, offering users an accessible, efficient, and balanced solution for enhanced mobility and overall quality of life.

[0006] There is, therefore, a requirement in the art to overcome the above-mentioned problems associated with providing a simple, cost-effective, and efficient self-balancing assembly for a prosthetic leg.OBJECTS OF THE PRESENT DISCLOSURE
