Assessment of a newly developed, active pneumatic-driven, sensorimotor test and training device.

ABSTRACT: The sensorimotor system (SMS) plays an important role in sports and in every day movement. Several tools for assessment and training have been designed. Many of them are directed to specific populations, and have major shortcomings due to the training effect or safety. The aim of the present study was to design and assess a dynamic sensorimotor test and training device that can be adjusted for all levels of performance. The novel pneumatic-driven mechatronic device can guide the trainee, allow independent movements or disrupt the individual with unpredicted perturbations while standing on a platform. The test-reliability was evaluated using intraclass correlation coefficient (ICC). Subjects were required to balance their center of pressure (COP) in a target circle (TITC). The time in TITC and the COP error (COPe) were recorded for analysis. The results of 22 males and 14 females (23.7 ± 2.6 years) showed good to excellent test-retest reliability. The newly designed Active Balance System (ABS) was then compared with the Biodex Balance System SD® (BBS). The results of 15 females, 14 males (23.4 ± 1.6 years) showed modest correlation in static and acceptable correlation in dynamic conditions, suggesting that ABS could be a reliable and comparable tool for dynamic balance assessments.

Project description:Implementation outcome measures are essential for monitoring and evaluating the success of implementation efforts. Yet, currently available measures lack conceptual clarity and have largely unknown reliability and validity. This study developed and psychometrically assessed three new measures: the Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), and Feasibility of Intervention Measure (FIM).Thirty-six implementation scientists and 27 mental health professionals assigned 31 items to the constructs and rated their confidence in their assignments. The Wilcoxon one-sample signed rank test was used to assess substantive and discriminant content validity. Exploratory and confirmatory factor analysis (EFA and CFA) and Cronbach alphas were used to assess the validity of the conceptual model. Three hundred twenty-six mental health counselors read one of six randomly assigned vignettes depicting a therapist contemplating adopting an evidence-based practice (EBP). Participants used 15 items to rate the therapist's perceptions of the acceptability, appropriateness, and feasibility of adopting the EBP. CFA and Cronbach alphas were used to refine the scales, assess structural validity, and assess reliability. Analysis of variance (ANOVA) was used to assess known-groups validity. Finally, half of the counselors were randomly assigned to receive the same vignette and the other half the opposite vignette; and all were asked to re-rate acceptability, appropriateness, and feasibility. Pearson correlation coefficients were used to assess test-retest reliability and linear regression to assess sensitivity to change.All but five items exhibited substantive and discriminant content validity. A trimmed CFA with five items per construct exhibited acceptable model fit (CFI = 0.98, RMSEA = 0.08) and high factor loadings (0.79 to 0.94). The alphas for 5-item scales were between 0.87 and 0.89. Scale refinement based on measure-specific CFAs and Cronbach alphas using vignette data produced 4-item scales (?'s from 0.85 to 0.91). A three-factor CFA exhibited acceptable fit (CFI = 0.96, RMSEA = 0.08) and high factor loadings (0.75 to 0.89), indicating structural validity. ANOVA showed significant main effects, indicating known-groups validity. Test-retest reliability coefficients ranged from 0.73 to 0.88. Regression analysis indicated each measure was sensitive to change in both directions.The AIM, IAM, and FIM demonstrate promising psychometric properties. Predictive validity assessment is planned.

Project description:BackgroundOlder people need to acquire knowledge and skills at first aid (FA) training tailored to them. Our research aimed to evaluate an FA training programme adapted for older people. We assumed that satisfaction with FA training, as well as knowledge of FA, would be higher among older people who received training according to an adapted programme compared to those who received training according to the existing programme for the general public.MethodsWe trained older people according to the existing FA programme for the general public and according to a new FA training programme adapted for older people. The new training program is shorter and focuses on FA contents that are more relevant for older people. We evaluated participants with a general assessment questionnaire (consisting of items regarding satisfaction, comprehensibility, length, and physical difficulty), a test on theoretical FA knowledge, and a test on practical cardiopulmonary resuscitation (CPR) knowledge. To ensure the homogeneity of the groups and to verify the impact on the results of the test of practical CPR knowledge, we also tested the participants regarding their psychophysical capabilities.ResultsA total of 120 people completed the free FA training sessions. The general assessment questionnaire score of participants who were trained based on the new FA training program was 19.3 (out of 20), which was statistically significantly (p < 0.05) higher than that of those trained based on the old program (general assessment score of 17.1). Participants who were trained based on the new program scored an average of 8.6 points on the theoretical FA knowledge test, while those who were trained based on the old program scored an average of 7.1 points, which was statistically significantly (p < 0.05) lower. In both programs, the same average scores (7.5 out of 10 points) on the practical CPR knowledge test was achieved. However, participants who participated in the FA course adapted for the older people gained practical CPR knowledge in a shorter time. Older people with a greater psychophysical capacity were more successful in performing CPR, regardless of which FA training programme they received.ConclusionsThe effectiveness of FA training is greater if older people are trained in accordance with a targeted programme adapted to the psychophysical limitations of the older people.
