Lower Limb Amputees

Prostheses are used to at least partly restore the body after limb amputation. Making the user accepting the prosthetic device as part of his or her body, i.e., inducing prosthesis embodiment, has been identified as major aim of prosthetic treatment. However, up to now, there is no consensus about the psychometric nature of prosthesis embodiment in limb amputees. In the present study, 118 unilateral lower limb amputees using a prosthesis were asked to complete an online questionnaire targeting prosthesis embodiment. Principal axis factoring revealed the factor structure of prosthesis embodiment, i.e., Ownership/Integrity, Agency, and Anatomical Plausibility, which resembles the embodiment structure previously found in normally-limbed participants. The majority of amputees achieved substantial embodiment of the prosthesis as assessed with the final version of the newly developed Prosthesis Embodiment Scale. Internal consistency was excellent, and test-retest reliability was acceptable, while the instrument was also sensitive for new prosthetic supply. Validation on the basis of relationships to locomotor capability, prosthesis satisfaction, and prosthesis adjustment was performed. The Prosthesis Embodiment Scale could be a valuable tool for the phenomenological assessment of successful body-prosthesis interaction in rehabilitative and research contexts, the latter which might further benefit from the comparability of psychometrically evaluated data.

This paper presents a possible prosthetic solution to excessive metabolic energy expended by transtibial (below the knee) amputees. This solution uses a four bar mechanism in conjunction with a spring, a motor, and a prosthetic foot as a lower limb prosthetic device. An optimization was previously performed on the mechanism parameters to mimic human ankle moments during normal walking. The cost function has been refined with the intent to reduce the required peak power input as well as to keep the link lengths of the four bar mechanism within an order of magnitude of each other. Design complications of the prototype that have arisen and likely resolutions are also included in this paper. Parts have been sized and justified based on likely size of the wearer, potential full-production costs of parts, and cost constraints.

Lower Limb Prostheses

This thesis proposes a novel lower-limb prosthetic device. Current prosthetics either have overly simplistic designs with inaccurate biomechanics or use delicate microprocessors that are easily damaged in harsh environments. This thesis aims to address these concerns by creating a novel device that combines a pneumatic damping system with a ball joint, resulting in a robust design with improved biomechanics. This prosthetic offers an affordable alternative that can be completely rebuilt while providing added comfort through improved biomechanics. Overall, this thesis contributes to the literature by proposing and discussing an innovative design for an affordable, comfortable, biomechanically sound alternative for lower limb prostheses.
