“…Three gymnasts showed CMC scores less than 0.7, two for the parallel and one for the T-shape hand position. Transverse plane motion has previously been reported to demonstrate reduced CMC values (<0.7), in different motor tasks including gait (Mackey, Walt, Lobb, & Stott, 2005), or landings (Ford et al, 2007). Differences in the elbow joint kinematic variability associated with each gymnast and skill technique support previous suggestions that the functionality of variability may not be generalized (Newell, van Emmerik, Lee, & Sprague, 1993;Bartlett et al, 2007), and that different motor strategies can be used to achieve the same motor task (Clark, 1995;Preatoni et al, 2013).…”

The aim of the present study was to conduct within-gymnast analyses of biological movement variability in impact forces, elbow joint kinematics and kinetics of expert gymnasts in the execution of the Round-off with different hand positions. Six international level female gymnasts performed 10 trials of the round-off from a hurdle step to a back-handspring using two hand potions: parallel and T-shape. Two force plates were used to determine ground reaction forces.Eight infrared cameras were employed to collect the kinematic data automatically. Within gymnast variability was calculated using biological coefficient of variation (BCV) discretely for ground reaction force, kinematic and kinetic measures. Variability of the continuous data was quantified using coefficient of multiple correlations (CMC). Group BCV and CMC were calculated and T-test with effect size statistics determined differences between the variability of the two techniques examined in this study. The major observation was a higher level of biological variability in the elbow joint abduction angle and adduction moment of force in the T-shaped hand position. This finding may lead to a reduced repetitive abduction stress and thus protect the elbow joint from overload. Knowledge of the differences in biological variability can inform clinicians and practitioners with effective skill selection. Highlights · Change in technique results in change in movement variability· Increased variability in elbow joint abd/adduction in the T shaped technique · Lower repeatability for internal/external rotation angles suggests specific motor strategies

“…In the present study, there was a slight increase in the duration of the stance phase, which can also be explained by the small reduction in velocity on the second day of testing. Mackey et al 3 evaluated the spatiotemporal parameters of children with hemiplegic CP and with approximately the same age as those of the present study. The authors claim they did not find any significant differences between parameters of stride length, gait cycle length, cadence and velocity, which is in agreement with the results of the present study.…”

“…These neuromusculoskeletal disorders affect upright stance, balance, and the ability to walk. As a consequence, gait performance in these children is poor when compared to that of normal children, leading to difficulties in carrying out daily and even leisure activities [1][2][3][4] . The current techniques of three-dimensional gait analysis allow a quantitative description of lower limb movements during gait.…”

© Revista Brasileira de FisioterapiaRepeatability of spatiotemporal gait parameters: comparison between normal children and children with hemiplegic spastic cerebral palsyRepetibilidade dos parâmetros espaço-temporais da marcha: comparação entre crianças normais e com paralisia cerebral do tipo hemiplegia espástica AbstractObjective: To evaluate the repeatability of spatiotemporal gait parameters by means of a comparative study between normal children and children with cerebral palsy (CP). Methods: The sample consisted of 17 children divided into two groups: a group of nine children with spastic hemiplegia CP and a group of eight normal children. The children were evaluated by the same researcher in two different sessions, with a one-week interval between the sessions. The children walked at self-selected velocities, and six attempts were performed at each session to represent the average. To record the spatiotemporal parameters, the Peak Motus system was used with two SVHS video cameras with an acquisition rate of 60 Hz. The intra-class correlation coefficient (ICC) and Bland-Altman concordance limits were chosen for data analysis. Results: The results demonstrated that the children with CP presented lower velocity and shorter cycles than the normal children in sessions 1 and 2. For all the spatiotemporal parameters, the two groups presented moderate to excellent ICC values, i.e. greater than 0.70. Conclusion: It can be concluded that the two groups presented good levels of repeatability for all the parameters analyzed when six attempts were used to represent the average.Key words: gait; children; cerebral palsy; repeatability. ResumoObjetivo: Avaliar a repetibilidade das medidas dos parâmetros espaço-temporais da marcha por meio de um estudo comparativo entre crianças normais e crianças com paralisia cerebral (PC). Métodos: A amostra foi composta por 17 crianças divididas em dois grupos: um grupo de nove crianças com PC do tipo hemiplegia espástica e um grupo com oito crianças normais que foram avaliadas pelo mesmo pesquisador em duas sessões diferentes, com intervalo de uma semana entre as sessões. As crianças caminharam em velocidade autosselecionada e foram utilizadas seis tentativas nas sessões 1 e 2 para representar a média. Para registro dos parâmetros espaço-temporais, foi utilizado o sistema Peak Motus, com duas câmeras de vídeo SVHS com taxa de aquisição de 60 Hz.Coeficiente de correlação intraclasse (ICC) e limites de concordância de Bland-Altman foram escolhidos para análise dos dados.Resultados: Os resultados demonstraram que as crianças com PC apresentaram menor velocidade e comprimento do ciclo do que as crianças normais para as sessões 1 e 2. Para todos os parâmetros espaço-temporais, os dois grupos apresentaram valores de ICC de excelentes a moderados, ou seja, maior do que 0,70. Conclusão: Pode-se concluir que os dois grupos apresentaram níveis bons de repetibilidade para todos os parâmetros analisados quando seis tentativas foram utilizadas para representar a média.

“…The tridimensional analysis is an important tool for making clinical decisions about the adopted therapeutic technique [16][17] . However, it is often not available as a routine evaluation, unlike MACS, which represents a clinical scale that is easy to apply and does not require previous training 5 .…”

| The aim of this study was to verify relation between kinematic variables of temporal-spatial parameters and manual ability and between own temporal-spatial variables during the movement of bring a mug to the mouth in adults with dyskinetic cerebral palsy (DCP). Sixteen adults with DCP were evaluated by MACS (Manual Ability Classification System), and by temporal-spatial variables of tridimensional kinematics of the movement to bring a bug to the mouth by means of 9 cameras infra-red Vicon ® MX 40 (Oxford Metrics Group, Oxford, UK). The Spearman correlation coefficient (ρ) was used to correlate variables. As a result, we found weak correlation between the classification of manual ability and the adjusting phase (ρ=0.219), the velocity variables − average velocity (ρ=-0.313), peak velocity (ρ=-0.282) and time to peak velocity (ρ=-0.250).No correlation was found between the variables going and returning phase and MACS. Moderate correlation was found between going and returning phase (ρ=0.559), between the going phase and time to peak velocity (ρ=0.518) and between the adjusting phase and peak velocity (ρ=-0.562). A strong correlation was found between the mean velocity and peak velocity (ρ=0.947) and between the adjusting phase and average velocity (ρ=-0.635).In conclusion, functional impairment may be related to longer adjusting phase and decrease of movement speed in subjects with PCD. Kinematic variables were related toCorrelation between temporal-spatial parameters and manual ability of adults with dyskinetic cerebral palsy each other in moderate and strong way and indicated that the phases runtime influences the movement speed.
