Spatiotemporal gait parameters influencing functional mobility of people with lower limb amputation.

Background: Walking speed is a measure of functional mobility that is relatively easy to quantify. In people with lower limb amputation, reduced walking speed has been linked with specific atypical spatiotemporal gait parameters. However, the influence of atypical spatiotemporal gait parameters on the walking speed of people with unilateral transtibial amputation (TTA) and transfemoral amputation (TFA) remains unclear.

Precommitment can allow decision makers to maintain trust when de-escalating commitment.

Following through on commitments builds trust. However, blind adherence to a prior course of action can undermine key organizational objectives. How can this challenge be resolved? Four primary experiments and five supplemental experiments (collective = 7,759, all preregistered) reveal an effective communication strategy: precommitment (i.

Children's amputee mobility predictor-Assessing the functional capability of children with leg length discrepancy.

Objective: The study purpose was twofold: (1) to develop the Children's Amputee Mobility Predictor and establish its content and social validity and (2) to determine its intra and inter-rater reliability.

Design: A reliability and validity study.

Setting: Pediatric rehabilitation hospital.

Going beyond the "self" in self-control: Interpersonal consequences of commitment strategies.

Commitment strategies are effective mechanisms individuals can use to overcome self-control problems. Across seven studies (and two supplemental studies), we explore the negative interpersonal consequences of commitment strategy choice and use. In Study 1, using an incentivized trust game, we demonstrate that individuals trust people who choose to use a commitment strategy less than those who choose to use willpower to achieve their goals.

The Use of Three-Dimensional Images and Food Descriptions from a Smartphone Device Is Feasible and Accurate for Dietary Assessment.

Technology-assisted dietary assessment has the potential to improve the accuracy of self-reported dietary intake. This study evaluates MealScan3D (MS3D), a mobile device-based food recording system, which uses three-dimensional images to obtain food volumes and an application to capture algorithm-driven food intake data. Participants ( = 179) were randomly assigned and trained to record three meals using either MS3D or a written food record (WFR).

Conveying and detecting listening during live conversation.

Across all domains of human social life, positive perceptions of conversational listening (i.e., feeling heard) predict well-being, professional success, and interpersonal flourishing.

The "hearts-and-minds frame": Not all i-frame interventions are ineffective, but education-based interventions can be particularly bad.

Pitting i-frame policies against s-frame policies inadvertently propagates a false dichotomy that fails to distinguish between effective i-frame policies that directly change behaviors and ineffective education-based i-frame policies that try to change people's hearts and minds. We argue that people's fixation on changing hearts and minds may be an obstacle for behavioral science in policy.

The development and reliability testing of the Functional Lower-Limb Amputee Gait Assessment.

Objective: The study purpose was three-fold: (a) to describe the development of the Functional Lower-Limb Amputee Gait Assessment, (b) to determine its reliability with two groups of raters, physical therapists, and certified prosthetists, and (c) to determine the agreement on its results between the two groups.

Design: A reliability study.

Setting: Institution for higher education.

Modifying the five-time sit-to-stand test to allow use of the upper limbs: Assessing initial evidence of construct validity among lower limb prosthesis users.

The Five-time Sit-to-Stand (5xSTS) Test is a performance-based measure used by clinicians and researchers to assess the body functions needed to accomplish sit-to-stand transitions (e.g., lower limb strength, balance, and trunk control).

Reducing discrimination against job seekers with and without employment gaps.

Past research shows that decision-makers discriminate against applicants with career breaks. Career breaks are common due to caring responsibilities, especially for working mothers, thereby leaving job seekers with employment gaps on their résumés. In a preregistered audit field experiment in the United Kingdom (n = 9,022), we show that rewriting a résumé so that previously held jobs are listed with the number of years worked (instead of employment dates) increases callbacks from real employers compared to résumés without employment gaps by approximately 8%, and with employment gaps by 15%.

Clinical Resources for Assessing Mobility of People with Lower-Limb Amputation: Interviews with Rehabilitation Clinicians.

Introduction: Mobility tests are increasingly used in prosthetic rehabilitation to evaluate patient outcomes. Knowledge of the space, equipment, and time resources available to clinicians who work in different settings can guide recommendations for which tests are most clinically-feasible and promote coordination of mobility testing among members of the rehabilitation team. The primary aim of this study was to characterize the different resources available to clinicians for measuring mobility of people with lower limb amputation.

Use of Standardized Outcome Measures for People With Lower Limb Amputation: A Survey of Prosthetic Practitioners in the United States.

Objective: To assess the clinical resources available for the assessment of health outcomes in people with lower limb amputation and to understand barriers and facilitators associated with use of standardized outcome measures in clinical practice.

Design: Cross-sectional survey.

Setting: General community (online).

A 680,000-person megastudy of nudges to encourage vaccination in pharmacies.

Encouraging vaccination is a pressing policy problem. To assess whether text-based reminders can encourage pharmacy vaccination and what kinds of messages work best, we conducted a megastudy. We randomly assigned 689,693 Walmart pharmacy patients to receive one of 22 different text reminders using a variety of different behavioral science principles to nudge flu vaccination or to a business-as-usual control condition that received no messages.

Change in plasma α-tocopherol associations with attenuated pulmonary function decline and with CYP4F2 missense variation.

Background: Vitamin E (vitE) is hypothesized to attenuate age-related decline in pulmonary function.

Objectives: We investigated the association between change in plasma vitE (∆vitE) and pulmonary function decline [forced expiratory volume in the first second (FEV1)] and examined genetic and nongenetic factors associated with ∆vitE.

Methods: We studied 1144 men randomly assigned to vitE in SELECT (Selenium and Vitamin E Cancer Prevention Trial).

Variations in 2-Minute Walk Test outcomes for people with lower limb amputation in the outpatient clinic and research settings.

Background: This study determined the differences in 2-Minute Walk Test (2MWT) distances between people with lower limb amputations in clinical and research settings and described variations in test administration in various clinical settings.

Study Design: Retrospective Cross-sectional design.

Methods: The 2MWT for 290 patients with lower limb amputations were obtained from a medium-sized prosthetic company with locations within the central United States.

A Comparison of the Two-Minute Walk Test (2MWT) and Comprehensive High-level Activity Mobility Predictor (CHAMP) in People with a Leg Prosthesis.

Objective: To determine if the two-minute walk test (2MWT) could serve as an alternative measure of high-level mobility in lower limb prosthesis users when circumstances preclude administration of the Comprehensive High-level Activity Mobility Predictor (CHAMP).

Design: Cross-sectional study.

Setting: Indoor recreational athletic field and gymnasium.

Megastudies improve the impact of applied behavioural science.

Policy-makers are increasingly turning to behavioural science for insights about how to improve citizens' decisions and outcomes. Typically, different scientists test different intervention ideas in different samples using different outcomes over different time intervals. The lack of comparability of such individual investigations limits their potential to inform policy.

Willpower is a form of, but not synonymous with, self-control.

We build on Ainslie's discussion of willpower by highlighting another common misconception in the literature: the conflation of self-control and willpower. In our commentary, we identify this issue and discuss the importance of recognizing willpower not as synonymous with self-control, but rather as a subset of self-control. We describe a set of upstream strategies as more effective alternatives to willpower.

Usability Assessment of the Rehabilitation Lower-limb Orthopedic Assistive Device by Service Members and Veterans With Lower Limb Loss.

Introduction: Telehealth is an increasingly common approach to improve healthcare delivery, especially within the Veterans Health Administration and Department of Defense (DoD). Telehealth has diminished many challenges to direct access for clinical follow-up; however, the use of mobile telehealth for specialty rehabilitative care is emerging and is referred to as telerehabilitation. As early adopters of telehealth, the Veterans Affairs and DoD have supported collaborated efforts for programs designed to increase the access and quality of rehabilitative care while improving the functional ability of our service members (SMs) and veterans with lower limb amputation (LLA).

The Utility of the 2-Minute Walk Test as a Measure of Mobility in People With Lower Limb Amputation.

Objectives: To establish reference values for the 2-minute walk test (2-MWT) distance and gait speed in people with a lower limb amputation (LLA) who are prosthetic ambulators. Also, to describe the differences in distance and gait speed between sexes, causes of amputation, levels of amputation, health risk classification, functional levels, and age groups.

Design: Cross-sectional study.

Signing at the beginning versus at the end does not decrease dishonesty.

Honest reporting is essential for society to function well. However, people frequently lie when asked to provide information, such as misrepresenting their income to save money on taxes. A landmark finding published in PNAS [L.

The Effectiveness of the DoD/VA Mobile Device Outcomes-Based Rehabilitation Program for High Functioning Service Members and Veterans with Lower Limb Amputation.

Introduction: The objective was to determine if the Mobile Device Outcomes-based Rehabilitation Program (MDORP) improved strength, mobility, and gait quality in service members (SMs) and Veterans with lower limb amputation (LLA).

Methods: Seven SMs and 10 Veterans with LLA enrolled and were trained to use a mobile sensor system, called Rehabilitative Lower Limb Orthopedic Analysis Device (ReLOAD). ReLOAD provided participants with real-time assessment of gait deviations, subsequent corrective audio feedback, and exercise prescription for normalizing gait at home and in the community.

What we can learn from five naturalistic field experiments that failed to shift commuter behaviour.

Across five field experiments with employees of a large organization (n = 68,915), we examined whether standard behavioural interventions ('nudges') successfully reduced single-occupancy vehicle commutes. In Studies 1 and 2, we sent letters and emails with nudges designed to increase carpooling. These interventions failed to increase carpool sign-up or usage.
