Dynamic Stiffness of Pediatric Prostheses During Rapid Loading
Conclusions Forefoot contact mitigates force transmission in landing. Overall, the feet exhibited a large range of force, deformation, and stiffness results, indicating the possibility of activity-specific individualized prescription. (Source: JPO Journal of Prosthetics and Orthotics)

Finite Element Simulation of Prosthetic Foot Adaptation to Mediolateral-Angled Cross-Slopes
Conclusions For full-width foot variations of stiffness, body mass, and width, properties that enabled maintenance of forward velocity during flat-ground walking gait resulted in mixed effectiveness on cross-slopes. Reducing foot stiffness resulted in deformation of the foot on cross-slopes, which reduced mediolateral displacement but increased forward velocity and vertical displacement. Increasing foot stiffness maintained vertical position and forward velocity but reduced foot contact and increased mediolateral displacement. Full-length splits of the foot into two or three cantilever springs resulted in less mediolater...

Early Upper-Limb Prosthetic Fitting and Brain Development: Considerations for Success
Conclusions Neurodevelopmental principles explain how neuronal connections are created when a child's brain is most receptive to environmental input. A child's use of motor skills to interact with the environment leads to cognitive, social and emotional development. Brain development studies, therefore, support early upper-limb prosthetic fitting. Because the development of grasp and the use of both hands together to manipulate an object is a progression, the timing of prosthetic fittings to match the needs of the developing brain is critical. Fitting an infant with a passive prosthesis and then soon transitioning to a m...

Comparative Effectiveness of Microprocessor-Controlled and Carbon-Fiber Energy-Storing-and-Returning Prosthetic Feet in Persons with Unilateral Transtibial Amputation: Patient-Reported Outcome Measures
This study aimed to examine differences in patient-reported balance, mobility, socket comfort, and preference between an ESAR foot and an MPA in persons with unilateral transtibial amputation (UTA). Materials and Methods Twenty-three participants with UTA enrolled in an institutional review board–approved, randomized crossover protocol with ESAR (Pacifica LP) and microprocessor-ankle configurations (Kinnex, Freedom Innovations) and a 4-week accommodation period. The outcome measures collected included Activities Specific Balance Confidence Scale (ABC), Prosthesis Evaluation Questionnaire–Mobility Subscale (PEQ-MS), ...

The Use of the Gradual Yielding Mechanism During Downhill Walking in Persons With Transfemoral Amputation—A Case Study
Conclusions First, the gradient at which the UTFs first used the yielding mechanism was found to be individual. Second, the yielding mechanism induced different alterations in spatiotemporal parameters to the participant walking at higher speed when not using the yielding mechanism. Third, using an articulating prosthetic ankle component did not alter the yielding gait pattern in two individuals with unilateral transfemoral amputation. The individual differences highlight the need for individual setups taking the different components of the prosthetic limb into account. (Source: JPO Journal of Prosthetics and Orthotics)

Efficacy of Ankle Supports on Dynamic Postural Control in Patients with Chronic Ankle Instability
Conclusions The soft ankle support has more effect on the balance of the CAI patients in comparison with the semirigid orthosis. (Source: JPO Journal of Prosthetics and Orthotics)

Comparison of Measurement Properties of the Mobility Section of the Prosthesis Evaluation Questionnaire on a Visual Analogue Scale and Its Modified Version with Five Response Categories
Conclusions The original PEQ-VAS Mobility Section and the modified PEQ-MS12/5 have moderate measurement differences; the results are thus not directly comparable. Both measures provide reliable and valid scores, but the modified version is easier to complete and analyze in clinical work. (Source: JPO Journal of Prosthetics and Orthotics)

Brace Compliance, Sex, and Initial Cobb Angle as Predictors of Immediate In-Brace Curve Correction in Adolescents With Scheuermann’s Kyphosis
CONCLUSIONS Results of the current study indicated that the amount of in-brace curve correction is primarily affected by brace compliance and initial Cobb angle. Brace compliance, curve correction, and pad pressure in boys were significantly higher than in girls. (Source: JPO Journal of Prosthetics and Orthotics)

Characteristics of Delphi Processes in Orthotics and Prosthetics Research
Conclusions Although the Delphi method is a common consensus process used in orthotics and prosthetics research, study methods vary and do not always follow recommended guidelines. Guidelines for future Delphi processes in orthotics and prosthetics research can be developed based on the data collected in this review. It is likely that there will be an increase in the number of Delphi studies conducted in this field in the future. Understanding the way this method has been implemented in previous studies can inform the design of future studies and may result in a more consistent application of this valuable research metho...

Open-Source Three-Dimensional Printable Infant Clubfoot Brace
Conclusions The 3D-printed brace has the features of commercially available braces while significantly reducing the cost, making this clubfoot brace particularly appropriate for use in developing countries. In addition, the results indicated that this model of distributed manufacturing of medical technology is technically and economically appropriate through much of the Global South.
