Biomechanical gait parameters change with increasing virtual height in a child with spastic cerebral palsy: A case report.

Virtual height exposure coupled with motion capture is feasible to elicit changes in spatiotemporal, kinematic, and kinetic gait parameters in a child with cerebral palsy and should be considered when investigating gait in real-world-scenarios.

Consequences of Virtual Reality Experience on Biomechanical Gait Parameters in Children with Cerebral Palsy: A Scoping Review.

Virtual reality (VR), coupled with motion tracking, can investigate walking in a controlled setting while applying various walking challenges. The purpose of this review was to summarize the evidence on consequences of VR on biomechanical gait parameters in children with cerebral palsy. MEDLINE, Embase and Web of Science were searched. Among 7.574 studies, screened by two independent reviewers, seven studies were included, analyzing treadmill (n = 6) or overground walking (n = 1) under VR. Most frequently reported were the spatiotemporal parameters walking speed, stride length, step width, stance phase, and the kinematic parameters range of knee flexion and peak ankle dorsiflexion. However, methodological approaches and reporting of the results were inconsistent among studies. This review reveals that VR can complement information gained from clinical gait analysis. However, this is still an emerging field of research and there is limited knowledge on the effect of VR on gait parameters, notably during overground walking.

Integration of the Insured Person's Perspective in the Quality Assessment of Medical Evaluations Abstract. In the current practice of medical work disability evaluations and other pension assessments, insured persons in Switzerland lack the possibility to routinely provide feedback on the extent to which they felt treated with dignity and respect by medical experts, which, according to occasional complaints, does not always seem to be the case. In order to be able to systematically capture such aspects of interactive fairness, we developed a questionnaire, the Basel Fairness Questionnaire (BFQ). The BFQ contains 30 statements such as «The reviewer listened to me.¼, which the insured person can agree to on four levels (from «I do not agree at all.¼ to «I fully agree.¼). For validating the questionnaire, 305 claimants for disability pensions completed the BFQ after their medical work disability evaluation. A factor analysis conducted on the answered questions confirmed our assumption that the BFQ questions covered the areas of 1) respect and trust, 2) participation, 3) case familiarity of the expert, and 4) transparency of the evaluation process. Furthermore, our study demonstrated divergent and convergent validity of the BFQ with other questionnaire instruments. The BFF opens up the possibility to capture the abstract concept of fairness by means of assessments of concrete expert behavior. We expect that the questionnaire can thus contribute to quality assurance in this sensitive area.

Perceived fairness of claimants undergoing a work disability evaluation: Development and validation of the Basel Fairness Questionnaire.

BACKGROUND: There are currently no tools for assessing claimants' perceived fairness in work disability evaluations. In our study, we describe the development and validation of a questionnaire for this purpose. METHOD: In cooperation with subject-matter experts of Swiss insurance medicine, we developed the 30-item Basel Fairness Questionnaire (BFQ). Claimants anonymously answered the questionnaire immediately after their disability evaluation, still unaware about its outcome. For each item, there were four response options, ranging from "strongly disagree" to "strongly agree". The construct validity of the BFQ was assessed by running a principal component analysis (PCA). RESULTS: In 4% of the questionnaires, the claimants' perception on the disability evaluation was negative (below the median of the scale). The PCA of the items responses followed by an orthogonal rotation revealed four factors, namely (1) Interviewing Skills, (2) Rapport, (3) Transparency, and (4) Case Familiarity, explaining 63.5% of the total variance. DISCUSSION: The ratings presumably have some positive bias by sample selection and response bias. The PCA factors corresponded to dimensions that subject-matter experts had beforehand identified as relevant. However, all item ratings were highly intercorrelated, which suggests that the presumed underlying dimensions are not independent. CONCLUSION: The BFQ represents the first self-administered instrument for measuring claimants' perceived fairness of work disability evaluations, allowing the assessment of informational, procedural, and interactive justice from the perspective of claimants. In cooperation with Swiss assessment centres, we plan to implement a refined version of the BFQ as feedback instrument in work disability evaluations.
