The development of advanced prosthetic devices that can be seamlessly used during an individual's daily life remains a significant challenge in the field of rehabilitation engineering. This study comp...
Adaptive sports are a vital component in the continuum of rehabilitation for people with limb loss/limb deficiency (LL/LD), across the lifespan. Identifying the barriers and understanding health care ...
Assessing the user perspective on residual limb health problems is particularly important for amputation care, given the relationship between residual limb health and prosthetic satisfaction. Only 1 m...
The objective of this study was to examine the psychometric properties of a modified PEQ Residual Limb Health scale in a sample of persons with ULA....
The study involved a telephone survey of 392 prosthesis users with ULA, with a 40-person retest sample....
The PEQ item response scale was modified to a Likert scale. The item set and instructions were refined in cognitive and pilot testing. Descriptive analyses characterized the prevalence of residual lim...
Sweating and prosthesis odor were prevalent at 90.7% and 72.5%, respectively; blisters/sores (12.1%) and ingrown hairs (7.7%) were the least prevalent problems. Response categories were dichotomized f...
The modified scale had excellent structural validity, fair person reliability, very good test-retest reliability, and no floor or ceiling effects. The scale is recommended for use with persons with wr...
Hip muscles play a prominent role in compensating for the loss of ankle and/or knee muscle function after lower limb amputation. Despite contributions to walking and balance, there is no consensus reg...
Twenty-eight LLP users (14 transtibial, 14 transfemoral, 7 dysvascular, 13.5 years since amputation), and 28 age- and gender-matched controls participated in a cross-sectional study. Maximum voluntary...
A significant 2-way interaction between leg and muscle group indicated normalized peak torque differed among combinations of muscle group and leg (p < 0.001). A significant simple main effect of leg (...
Our results suggest that it is the intact, rather than the residual limb, that is weaker. These findings may be due to methodological choices (e.g., normalization), or biomechanical demands placed on ...

Owing to the lack of trained professionals in amputee care, the pediatrician is often required to assist in the care of children with limb deficiencies. An overview of the causes and epidemiology of l...
The use of prostheses in individuals with limb loss increases the risk of maceration, friction, and pressure-induced skin injuries due to the vulnerability of the residual limb and the close contact w...
Prostheses are a primary rehabilitative intervention for people after lower limb amputation. To appropriately measure the effectiveness of prosthetic interventions, valid and reliable measures of pros...
Rasch validation of the German translation of the PLUS-M short forms in people with lower limb amputation....
This study is based on a cross-sectional survey of prosthesis-using lower limb amputees from a nation-wide cohort....
PLUS-M data (the 7-item and the 12-item shortforms; PLUS-M-7 and PLUS-M-12, respectively) from 194 lower limb prosthesis users were subjected to Rasch analysis, an advanced statistical method for asse...
Analysis showed appropriate rating scale functioning, good internal construct validity (item fit), unidimensionality, and good targeting of the PLUS-M-7 and PLUS-M-12 short forms. Moreover, the greate...
Rasch analysis of the German translation of both PLUS-M short forms showed good psychometric qualities. In addition, our study showed that test scores from the PLUS-M-12 are more accurate. Therefore, ...
Pediatric limb loss or limb deficiency is uncommon in the United Sates occurring 1 per 1943 live births per year, with a ratio of 2:1 upper to lower extremity....
Relative motion between the residual limb and socket in individuals with transtibial limb loss can lead to substantial consequences that limit mobility. Although assessments of the relative motion bet...
This study aims to develop analytical tools using DSX to quantify the dynamic, in vivo kinematics between the residual limb and socket and the mechanism of residual tissue deformation....
A lower limb cadaver study will first be performed to optimize the placement of an array of radiopaque beads and markers on the socket, liner, and skin to simultaneously assess dynamic tibial movement...
This study was funded in October 2021. Cadaver testing began in January 2023. Enrollment began in February 2024. Data collection is expected to conclude in December 2025. The initial dissemination of ...
The successful completion of this study will help develop analytical methods for the accurate assessment of residual limb-socket motion. The results will significantly advance the understanding of the...

This article describes fundamental lower limb prosthesis concepts and componentry, including skeletal structure (endoskeletal vs exoskeletal), transtibial and transfemoral sockets, prosthetic suspensi...
