Surfing Performance in Para Surfers with Lower-Limb Amputations: A Cross-Sectional Study
Conclusions Surfers with TFA who stood or kneeled received higher judged wave scores than surfers with TTA; however, no other significant significance was found for TFA intragroup comparisons or prior surf experience. The data size was too small for confirmatory analysis. Results appeal to a new need for inquiry on para surfers with TFA and TTA, specifically biomechanical performance surfing differences. Clinical Relevance Individuals with transfemoral and/or transtibial amputations can participate competitively in para surfing contests. Surfers with TFAs can successfully compete either standing with a prosthesi...

Mechanically and Physiologically Optimizing Prosthetic Elevated Vacuum Systems in People with Transtibial Amputation: A Pilot Study
Conclusions Practitioners may use individual responses to optimize socket vacuum pressure settings, balancing the mechanical and physiological effects of EV for improved clinical outcomes. Clinical Relevance Understanding the effects of various socket vacuum pressure settings on individuals’ outcomes may improve clinical implementation of EV. In this study, the highest available vacuum setting did not always produce maximum comfort and limb fluid volume benefit, and similar levels of suspension were achieved with lower vacuum settings.

Biomechanical Measures for Fall Risk Assessment and Fall Detection in People with Transfemoral Amputations for the Next-Generation Prostheses: A Scoping Review
Conclusions Two classes of biomechanical markers for fall risk assessment have the potential to be incorporated in self-contained transfemoral powered prostheses equipped with sensory network and suitable computational capabilities. The first consists of kinematic/kinetic variables of some prosthesis components (e.g., foot acceleration, force loading the pylon, knee angle) to detect either an abrupt lack of balance or a fall-related occurrence as a consequence of knee buckling, slipping, or tripping. The second involves implementing automatic procedures to allow pwTFA to routinely carry out clinical tests, such as the ...

Material Selection for Diabetic Custom Insoles: A Systematic Review of Insole Materials and Their Properties
Conclusions The diversity of studies and study designs to date precludes the ability to recommend one type of material over the other. Still some general considerations can be made. For solo-material insoles, moderately deformable materials are preferable, balancing the need for offloading with the need for durability. Increasing the thickness may increase the longevity of the insoles. Combining materials of different properties seems to enhance both the offloading capability and durability of insoles. Clinical Relevance When using a single-material design, moderately deformable materials are preferable. Combini...

Is Maximum Available Hip Extension Range of Motion of the Residual Limb Reached During Passive Prone Lying in the Acute Stage After Dysvascular Transtibial Amputation?
Conclusions Our findings show that, on average, patients after a TTA have significantly greater peak hip extension angle in the MTT position compared with the PL position. Thus, passive PL may not be as effective of a stretching position for preventing a hip flexion contracture after a TTA, because PL does not always extend the patient's hip to its maximum available ROM, due to the reduced ability to control the pelvis from tilting anteriorly. Clinical Relevance Adequate hip flexor length is positively correlated with gait parameters, which include increased velocity and step length in people using a prosthesis ...
