Trends in Physical Fitness in Children and Adolescents Within the Past 18 Years (DONALD Study).

Objective: To evaluate the trends in physical fitness in children and adolescents.

Method: The present study focusses on a longitudinal analysis of the single two-legged jump (S2LJ) from children and adolescents, who participated in the DONALD study from 2004 till 2022. P /body mass (power, surrogate for muscular performance), V (bounce speed, surrogate for coordination), F /body mass (force, surrogate for muscular strength) and (Nerve-Muscle Index, surrogate for jump efficiency) were examined by linear mixed models and propensity-score(PS)-matching analysis.

Motor improvement in children with PMM2-CDG syndrome following a six-month rehabilitation treatment utilising whole-body vibration; a retrospective study.

Objective: The aim of this study was to assess the effect of a six-month interval rehabilitation treatment on motor function of children with PMM2-CDG syndrome (#212065 Congenital disorder of glycosylation, Type Ia; CDG1A, OMIM catalogue number).

Methods: The concept 'Auf die Beine' (Center for Prevention and Rehabilitation of the University of Cologne, Germany) combines two short inpatient stays (1 to 2 weeks) with a six-month whole-body vibration (WBV) home-training program. 13 patients with PMM2-CDG syndrome participated in this concept from 2006 until 2015.

Multivariable reference centiles for maximum grip strength in childhood to young adults.

Objectives: Maximum grip strength (mGS) is a useful predictor of health-related outcomes in children and adults. The aim of the study was to generate sex- and age-adjusted reference centiles for mGS for children, adolescents and young adults, while adjusting for body height and body mass index (BMI).

Methods: A retrospective analysis of longitudinal data from children and young adults participating in the DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study (single center, open cohort study) from 2004 to 2022 was conducted.

Using artificial intelligence-based technologies to detect clinically relevant changes of gross motor function in children with cerebral palsy.

Aim: To compare the 66-item Gross Motor Function Measure (GMFM-66) with the reduced version of the GMFM-66 (rGMFM-66) with respect to the detection of clinically relevant changes in gross motor function in children with cerebral palsy (CP).

Method: The study was a retrospective single centre analysis of children with CP who participated in a rehabilitation programme. Overall, 1352 pairs of GMFM-66 and rGMFM66 measurements with a time interval of 5 to 7 months were available.
