#1
Mitchell Farrar, Emma Thomas
BACKGROUND: Shock-attenuating pylons are commonly fitted to prostheses in order to compensate for the anatomical and biomechanical shock-absorbing features of the lower limb removed upon amputation. However, studies concerning their shock-attenuating capacity are highly variable and, to date, have not yet been reviewed, making them difficult to interpret and apply in clinical practice. OBJECTIVES: To synthesise and appraise the available literature examining the effectiveness of shock-attenuating pylons in attenuating shock upon limb loading compared to rigid pylons among lower limb amputees...

BACKGROUND: Research on adaptation to advanced upper limb prostheses is needed. OBJECTIVES: To (1) examine change in function, quality of life and community integration after prosthetic training, (2) determine whether change in outcomes varied by prosthesis complexity, and (3) compare patterns of change at 1 month for those who withdrew from the study and those who did not. STUDY DESIGN: Quasi-experimental time series. METHODS: Data were analyzed for 22 participants (18 completers)...

Elizabeth G Halsne, Cody L McDonald, Sara J Morgan, Sarah M Cheever, Brian J Hafner
BACKGROUND: Crossover feet incorporate features of energy-storing feet and running-specific feet. As such, crossover feet may be suitable for both daily ambulation and participation in physically demanding activities. OBJECTIVES: To compare crossover feet and energy-storing feet on performance-based tests including a range of low-level (e.g. sit-to-stand) and high-level (e.g. jogging) activities. STUDY DESIGN: Cross-sectional, repeated measures...

Nerrolyn Ramstrand, Simon Ramstrand
BACKGROUND: There are currently no national competency standards upon which to develop educational objectives for prosthetist/orthotists in Sweden. While standards have been developed in other countries, they cannot be applied without confirming their relevance in a Swedish context. OBJECTIVES: To describe and obtain consensus on core competencies required for newly graduated prosthetist/orthotists in Sweden. STUDY DESIGN: Modified Delphi process...

BACKGROUND: Prosthetists and orthotists have a responsibility to direct treatment toward enabling their clients to perform desired activities and to facilitate participation of their clients in all areas of life. This may include provision of assistive technologies to help clients meet goals related to participation in sexual activities. To help prosthetic and orthotic students develop competencies in dealing with the sexual health of their future clients, it is necessary to generate knowledge of their own perceived competence and capacity...

BACKGROUND: Foot pain and paresthesia are common in cycling, due to plantar pressure and repetitive loading. OBJECTIVES: The aim was to investigate the effect of foot insoles on plantar pressure of the foot in motorcycling, as well as self-reported comfort. STUDY DESIGN: A randomized crossover clinical trial. METHODS: A flexible foot pressure mat (GP MobilData WiFi® Gebiomized®) with different sizes was utilized. RESULTS: Maximum pressure values occurred predominantly in the hallux with 4...

Stefania Fatone, Jessica Yohay, Ryan Caldwell
BACKGROUND: This case study represented a unique opportunity wherein a long-time user of sub-ischial sockets had kept nearly every socket he wore for a decade. This individual let us borrow these sockets so we could digitize them and indirectly assess change in residual limb size over time by calculating changes in socket volume and circumferences over time. Case Description and Methods: Over a decade, the subject maintained a relatively stable body weight of 84-88 kg and received nine sub-ischial sockets...

Daniel Joseph Lee, Michael Wininger, David Mahler, Mark Parisi
BACKGROUND: The incidence and etiology of prosthetic services utilization is poorly understood during the first 90 days post-delivery of the initial lower limb prosthesis. This period is of critical importance, as prevailing policy dictates limits on the reimbursement for certain services provided during this time period. The first step in understanding the financial ramifications of such policy is to examine the taxonomy behind clinical encounters during this tenuous time period. OBJECTIVES: Quantify and categorize clinical encounters by incidence and etiology...

BACKGROUND AND AIM: Although Paralympic T42 class Men's 200 m sprints are currently competed by athletes with bilateral and unilateral transfemoral amputations, there may be performance differences between the groups. This study aimed to compare the spatiotemporal parameters of a 200-m sprint between bilateral and unilateral transfemoral amputees wearing running-specific prostheses. TECHNIQUE: We analyzed 29 races (nine sprinters) with bilateral or unilateral transfemoral amputations from publicly available Internet broadcasts...

BACKGROUND: Evaluating the effectiveness of a novel prosthetic device during walking is an important step in product development. OBJECTIVE: To investigate the efficacy of a novel quasi-passive ankle prosthetic device, Ankle Mimicking Prosthetic Foot 4.0, during walking at different speeds, using physiological determinants in transtibial and transfemoral amputees. STUDY DESIGN: Nonrandomized crossover design for amputees. METHODS: Six able-bodied subjects, six unilateral transtibial amputees, and six unilateral transfemoral amputees underwent a 6-min walk test at normal speed, followed by series of 2-min walking at slow, normal, and fast speeds...

BACKGROUND: Step counts, obtained via activity monitors, provide insight into activity level in the free-living environment. Accuracy assessments of activity monitors are limited among individuals with lower-limb amputations. OBJECTIVES: (1) To evaluate the step count accuracy of both monitors during forward-linear and complex walking and (2) compare monitor step counts in the free-living environment. STUDY DESIGN: Cross-sectional study. METHODS: Adult prosthetic users with a unilateral transtibial amputation were equipped with StepWatch and FitBit One™...

BACKGROUND: Through play, children develop motor, cognitive, social, and other life skills. Play barriers can impede physical and psychosocial benefits. OBJECTIVES: We describe participation in active play, fundamental movement skills, play environment characteristics, and potential play barriers for school-aged children (6-12 years) who use lower extremity prostheses. STUDY DESIGN: Cross-sectional questionnaire study. METHODS: A questionnaire was developed and administered online to parents of children 6-12 years who use lower extremity prostheses...

Simon Sw Li, Daniel Hk Chow
BACKGROUND: Usual guidelines recommend symmetric load carriage over asymmetric load carriage. Whether this recommendation is valid for subjects with asymmetric body alignment, such as those with scoliosis, remains unclear. Scoliosis is both a subject-dependent and time-variant condition. Interventions are generally employed to prevent the abnormal spinal curvature from progressing. OBJECTIVES: To investigate the effects of an asymmetric load carriage on lateral spinal deformity in participant with scoliosis...

BACKGROUND: Surfing with transfemoral knee prosthesis requires flexion of the hip, knee, and ankle and balance between flexibility and stiffness of the prosthetic limb. We report on Mr D, a transfemoral amputee, who wanted to surf again. Case Description and Methods: Technical specifications were based on Mr D's complaint. The prosthesis is salt water resistant and combines a shock absorber associated with elastic tendons to permit the knee to bend easily and to facilitate eccentric braking...

BACKGROUND: In 1970, Mori hypothesised the existence of an 'uncanny valley', whereby stimuli falling short of being fully human are found to be creepy or eerie. OBJECTIVES: To investigate how eerie people find different prosthetic hands and whether perceptions of eeriness can be accounted for by categorical ambiguity. STUDY DESIGN: Students participated in computerised experiments during which photographic images of hands were presented. METHODS: We compared photographs of prosthetic hands pre-selected as more (H+) or less human-like (H-), as well as mechanical and real hands...
