Validity, responsiveness, minimal detectable change, and minimal clinically important change of the Pediatric Motor Activity Log in children with cerebral palsy

OBJECTIVE: The present study aimed to estimate the reliability, standard error of measurement (SEM), and minimum detectable change (MDC) of the star excursion balance test (SEBT) in children with cerebral palsy (CP). METHODS: Eight children with CP (five boys and three girls, sixteen legs) participated in this study. Each child carried out the SEBT and was assessed by two examiners. To determine intra-rater reliability, the intra-class correlation coefficient (ICC) model (3, 3) was calculated. To determine the inter-rater reliability, the ICC model (2, 3) was computed. RESULTS: In terms of the intra-rater reliability of the SEBT, the ICC varied from 0.98 to 0.99 and the total ICC score was 0.99 (p< 0.001). For the inter-rater reliability, the ICC varied from 0.98 to 1.00 and the total ICC score was 0.99 (p< 0.001). The SEBT had an SEM of 2.63 and an MDC of 7.31. CONCLUSION: The SEBT is not only reliable with a small SEM, but is also a simple and cheap assessment of dynamic balance in children with CP.

AbstractBackground and Purpose. Older subjects after hip fracture walk more slowly than age-matched peers. The extent to which they walk more slowly is difficult to define because the standard error of the measure (SEM), sensitivity to change, and clinically important change have not been reported for gait speed. The purposes of this study were to quantify the SEM for habitual and fast gait speeds among older subjects after hip fracture, to define the minimal detectable change (MDC), and to estimate the minimal clinically important difference (MCID) for habitual gait speed. Subjects. A sample of 92 subjects after hip fracture was drawn from 3 studies that collected gait speed data. Methods. An estimate of the MDC was determined by use of the SEM. The MCID was determined from expert opinion and from a receiver operating characteristic (ROC) curve. Results. The SEM and the MDC were 0.08 m/s and 0.10 m/s for habitual speed and fast speed, respectively. Both methods of MCID estimation identified 0.10 m/s as a meaningful change in habitual gait speed. Discussion and Conclusion. The estimated MCID for gait speed of 0.10 m/s was supported by clinical expert opinion and the cutoff point of the ROC curve.

Test Retest Reliability

Abstract Background: Patellofemoral pain is a very common complaint in orthopedic sports medicine clinics. Disease-specific patient-reported outcome measures (PROMs) are useful for research and clinical practice; thus, it is important to have validated translations available for new PROMs. This study aims to translate and validate the Spanish version of the patellofemoral pain and osteoarthritis subscale of the knee injury and osteoarthritis outcome score (KOOS-PF).Methods: The KOOS-PF was translated and culturally adapted to Spanish following current guidelines, which included translation, back-translation, conciliation and pilot studies. Patients with a diagnosis of patellofemoral pain and/or osteoarthritis from one medical center were invited to participate and complete the questionnaire. The evaluation of the score included internal consistency (Cronbach´s alpha), floor and ceiling effects, measurement error, minimal detectable change and minimal important change. For test-retest reliability, the intraclass correlation coefficient (ICC) was used, and for responsiveness, the global rating of change (GROC) scale was measured one month later.Results: Sixty patients with patellofemoral pain and/or osteoarthritis were included in the study. The Spanish version showed very good internal consistency (Cronbach’s alpha: 0.93) and test-retest reliability (intraclass correlation coefficient: 0.82). Responsiveness was confirmed, with the KOOS-PF demonstrating a strong correlation with the GROC score (r 0.64). The minimal detectable change was 11.1 points, the minimal important change was 17.2 points, and there were no floor or ceiling effects for the score.Conclusions: The Spanish version of the KOOS-PF demonstrated very good measurement properties, including internal consistency, reliability and responsiveness. The KOOS-PF can be used in Spanish-speaking patients for clinical and research purposes in patellofemoral pain and osteoarthritis.Trial registration: Fundación Valle del Lili, Biomedical Research Ethical Committee: No. 01438.
