    Cerebral palsy (CP) characterizes a group of disorders of the development of posture and movement due to a non-progressive disturbance in immature brain. It is frequent that children show deficits in postural control. There is interest in knowledge about movement strategies used during anterior reaching until the limit of stability that justifies the lower performance of children with CP. The aim of this study was to evaluate the motor strategies used by children with CP during the Pediatric Reach Test (PRT). This cross-sectional, non probabilistic study was composed of a convenience selected sample of 28 children, aged between 6 and 14 years old, 14 with clinical diagnosis of CP, classified as I and II according to the Gross Motor Function Classification System (GMFCS) in CP group (CPG) and 14 with typical motor development in the control group (CG), paired by gender and age. After anthropometric data collected, children were evaluated by PRT, in combination with image capture and electromyographic for further analysis. Kinematic variables (displacement of the styloid process, time, mean velocity and deceleration index), angular variables (initial and final angle of the shoulder, hip, knee and ankle) and also electromyographic variables (latency and magnitude of muscle activation in anticipatory (APA) and compensatory postural adjustment (CPA) of the tibialis anterior, rectus femoris, lateral gastrocnemius, biceps femoris and erector spinae. For the kinematic analysis we used t-Student and for the electromyographic analysis the Mann-Whitney was used. Significance level of 5% was adopted. There was no difference between groups for weight and height variables, showing homogeneity of the sample. The CPG showed lower displacement, time and mean velocity, and higher deceleration index. The angular variables showed that both groups used the same strategy of motion, but the CPG showed greater initial flexion of shoulder, knee and ankle, characterizing the crouch posture. There were no differences between groups for muscle latency and magnitude of muscle activation in APA and CPA. We conclude that children with CP have lower performance in the PRT, with less motion control compared to their peers with typical motor development, and those changes of alignment evidenced by children with CP generate compensatory mechanisms that reflect the decreased efficiency of anterior reaching movement.

    Estratégias motoras de crianças com paralisia cerebral na postura sentada durante o alcance anterior

    Cerebral paralysis (CP) describes a group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. It is common to have deficits in postural control in these children. There is interest in knowing the movement strategies used during the previous range in the sitting posture, since this posture is widely used for children with CP to perform activities of daily living. The objective of this study was to evaluate the motor strategies used by children with CP during the Pediatric Reach Test (PRT) in the sitting posture. This crosssectional, no probabilistic study was composed of aconvenience selected sample of 40 children, aged 6 to 14 years, 20 with clinical diagnosis of CP, classified as I, II and III according to the Gross Motor Function Classification System (GMFCS) in the CP group (CPG)and 20 with typical motor development for the control group (CG), paired by age and gender. After anthropometric data colected, children were evaluated by PRT, which is the anterior reaching until to the limit of stability in sitting posture. The test was recorded and the captured images was used for subsequent three-dimensional reconstruction of the movement. Linear kinematic variables of the movement of the styloid process (displacement, time, mean velocity and deceleration index), and angles (initial and final angle of the shoulder, hip, knee and ankle joints) were analyzed. For the statistical analysis we applied the t-Student test for linear variables, and ANOVA with Bonferroni multiple comparison to the angular variables. The significance level of 0.05 was adopted. There was no difference between groups for the weight and height variables, showing the homogeneity of the sample. The CPG showed lower displacement, time, and mean velocity and higher deceleration index. The angular variables showed that both groups used the same movement strategy, but the children of CPG started the movement with higher shoulder flexion, and knees flexion, indicating that this posture with higher impairments can be a factor for lower distance reached, and negatively influences the level of functionality. We conclude that children with CP have lower performance in anterior reaching test in sitting posture, with lower displacement and motor control compared to their peers with typical motor development, and thechanges of alignment evidenced by children with CP generate compensatorymechanisms that reflected the decreased efficiency of anterior reaching movement.
