Kinetic and Kinematics Parameters of Hip in Gait for a Congenital Longitudinal Tibial Deficiency with Orthoprosthesis and Transfemoral Prosthesis: A Case Study
Conclusions This case study suggests that the new prosthesis provides removable and adaptable component; further, it delivers a comfortable sitting experience because of its new socket design and knee joint flexion. Clinical Relevance Patient satisfaction is better with TF prosthesis than with orthoprosthesis. TF prosthesis is more cosmetic than orthoprosthesis, provides a symmetrical gait pattern, decreases donning and doffing durations, and there is no uncomfortable protrusion when sitting (due to amputation of the foot and leg part).

Roll-Over Shape–Based Design of Novel Biomimetic Ankle-Foot Prosthesis
This study aimed to design the mechanical properties of ankle-foot prostheses to achieve specific ROSs during gait. Methods The authors developed a mathematical model that, when used in combination with ground reaction force and shank angle experimental data, predicts the ROS created by the novel Compliant and Articulating Prosthetic Ankle (CAPA) foot. The CAPA consists of four articulating components connected by torsion springs. Able-bodied individuals walked wearing a prosthetic simulator with the solid ankle cushioned heel foot, a dynamic response foot (the Renegade AT), and versions of the CAPA with distinctly ...

The Effects of Polycentric Knee Design and Alignment on Swing Phase Gait Parameters: A Simulation Approach
Conclusions This study shows that polycentric knees, which generally perform better than single-axis knees with improved stance stability and ease of push-off, can also perform well during swing in terms of knee extension before heel contact and foot clearance throughout swing. The extended moment arm for the weight of the shank and foot due to the superior location of the IC in polycentric knees is the reason for the improved swing performance of polycentric knees. Appropriate placement of the socket adapter, which affects A/P alignment, is crucial so that foot clearance during swing is not compromised. The insights o...

These findings, along with the noninvasive OCT imaging methods introduced here, would have the potential to improve clinical practice by enabling the development of rehabilitation techniques and therapeutics to better strengthen skin, thereby reducing the incidence of harmful skin breakdown.

Mobility Analysis of AmpuTees (MAAT 6): Mobility, Satisfaction, and Quality of Life among Long-Term Dysvascular/Diabetic Prosthesis Users—Results of a Cross-Sectional Analysis
Conclusions Those individuals with amputation secondary to dysvascular disease and diabetes who continue to participate in prosthetic rehabilitation appear to experience levels of mobility, Sat, and QoL 7 years after amputation comparable to that reported in the first 6 months postamputation. There may be a modest increase in Sat with receipt of an initial prosthesis, potentially due to an increased optimism for one's situation. Notably, the mobility levels observed in the dysvascular population through a range of long-term postamputation periods remain within a single standard deviation of the population mean for indi...

Investigating the Impact of the User Interface for a Powered Hip Orthosis on Metabolic Cost and User Comfort: A Preliminary Study
Conclusions The user interface may impact metabolic cost of walking and user comfort. Moving forward, it should be considered an essential element of powered orthosis design. It is critical to optimize the user interface in future powered hip orthotic designs due to minimal surface area available for weight-bearing and reduced number of actuated joints. Therefore, those interested in optimizing powered hip orthotic user interface designs should focus on loading anatomic structures, including the shoulders and iliac crests, and on supporting the curvature of the lumbar spine.

Conclusions DAFOs and MSS show positive effects, as observed in spatiotemporal parameters, gait indices, and kinematic data. Most kinematic effects occur at the ankle and knee joint.
