Abstract
Our aim in this study was to examine relationships between the motor activity ability, sensor-based kinematics and forward-backwards gait characteristics of children with cerebral palsy (CP). In this prospective cross-sectional study we studied 40 children with CP. We used the Pediatric Motor Activity Log Revised (PMAL-R) to assess motor activity, evaluated motion kinematics (acceleration and angular velocity) with a sensor-based application, applied the Edinburgh Visual Gait Score (EVGS) and the Timed Up and Go Test (TUG) to observe gait performance, and used the Three Meter Backward Walk Test (3MBWT) to assess backward gait. We found moderately positive significant correlations (r1 = 0.416, r2 = 0.418, p < 0.05) between the chilidren's minimum angular velocity on PMAL-R motor activity frequency (how often) and quality (how well) scores, respectively. We also found moderately negative significant correlations (r1 = -0.529, r2 = -0.521, p < 0.05) between PMAL-R frequency (how often) and quality (how well) scores with TUG, respectively. There were moderately high positive correlations (r1 = 0.415, r2 = 0.726, p < 0.05) between EVGS scores and 3MBWT and TUG scores, respectively. We concluded that angular velocity ability was moderately related to children's motor activity and showed that physical performance tests (TUG and 3MBWT) could monitor gait function and upper extremity motor activity level, including both forward and backward walking tasks, in children with CP.

Abstract
We investigated factors related to postural sway during sit-to-stand movement in children and adolescents with Down syndrome (DS). Our assessment of participants followed the biopsychosocial model. Body function and structure were represented by muscle strength and postural sway during sit-to-stand movement, which were assessed by manual muscle testing and kinetics analysis, respectively. The Gross Motor Function Measure and Pediatric Balance Scale depicted the activity component. In addition, we included these relevant contextual factors: age, Home Observation for Measurement of the Environment, family income, and maternal schooling. A correlation analysis verified a suspected association between biopsychosocial and postural sway variables. There were significant separated correlations between postural sway in the three phases of the sit-to-stand movement, and age, GMFM-88 dimension D, and muscle strength. Thus, postural control in sit-to-stand movement was related to biopsychosocial factors involving different life aspects of children and adolescents with DS, and these factors should be addressed in rehabilitation therapy intended to improve postural control among these individuals.

Abstract
Objective: Assess the effect of nonimmersive virtual reality (VR) training as complementary rehabilitation on body oscillation in children with cerebral palsy (CP) while standing on different bases of support and surfaces. Materials and Methods: Twenty-three children with unilateral CP randomly allocated to an intervention group (IG, n = 12) or control group (CG, n = 11). The IG underwent two weekly 50-minute sessions of VR training over 8 weeks, associated with conventional therapy, while the CG was submitted to two 45-minute sessions of conventional neurodevelopmental-based physiotherapy a week over the same time period. Participants were evaluated on a force platform under control conditions (CCs) (rigid surface, feet parallel); semitandem stance; flexible surface (FS) with feet parallel; and flexible surface in a semitandem (FSST) stance. The effect of the group and time factors on the center of pressure oscillation variables was analyzed by repeated-measures analysis of variance (ANOVA), with significance set at 0.05. Results: The main effect observed was for time on the FS, with a decline in the amplitude of mediolateral (ML Amp) (P = 0.01) and mediolateral root mean square (P = 0.01) after intervention. In the IG, ML Amp also declined after intervention under CCs (P = 0.02) and total velocity increased for FSST (P = 0.04). The percentage change was significant only in the IG. Conclusion: VR training as complementary rehabilitation can help improve body oscillation in children with CP and mild functional impairment. Nonimmersive VR can be considered a complementary tool for the physical rehabilitation of children with CP. This study was registered with the Brazilian Clinical Trials Registry (RBR-3zty4w).

Abstract
PURPOSE To compare the effects of upper extremity constraints on functional and dynamic postural control in children with hemiplegic cerebral palsy. MATERIALS AND METHODS Twelve children with hemiplegic cerebral palsy and 12 typically developing children ages 5 to 12 years (GMFCS I-II) were evaluated with the Timed Up and Go (TUG) and Biodex Balance System during three upper extremity (UE) conditions: 1) Free UEs (no constraints), 2) Simple UE constraint (unaffected/dominant UE constrained with a sling), and 3) Difficult UE constraint (Simple constraint plus the other UE holding cup of water). RESULTS The UE condition had significant effects on Overall Stability Index (OSI) (F(2,44) = 24.899, p < .001), Medial-Lateral Stability Index (MLSI) (F(2,44) = 4.380, p = .018), Anterior-Posterior Stability Index (F(2,44) = 6.187, p = .004), and TUG scores (F(2,44) = 113.372, p < .001). Group was significant for OSI (F(1,22) = 7.906, p = .010), MLSI (F(1,22) = 13.113, p = .002), and TUG (F(1,22) = 36.282, p < .001). CONCLUSIONS The upper extremity appears to have a role in maintaining functional balance and postural stability in children with hemiplegic cerebral palsy and should be considered during intervention programs.

Abstract
We investigated the influence of sex and age in postural sway during sit-to-stand (STS) in children and adolescents of 5-15 years. We evaluated sway during STS in 86 typical participants. STS was divided into three phases: preparation, rising, and stabilization. We calculated for each phase: area, anterior-posterior, and medial-lateral velocity of center-of-pressure sway. We applied a stepwise multiple linear regression model to determine if age and sex might be predictors of postural sway during STS. Only age was associated with sway, accounting for between 6.5% and 14.6% of the variability in sway during STS. The age of the subject influences postural sway during STS, but in a small amount. This variable should be taken into account as a variable of control in the assessment of dynamic postural control. Moreover, postural stability during STS was not associated with the sex of the participants.

Effects of motor and cognitive manipulation on the dual-task costs of center of pressure displacement in children, adolescents and young adults: A cross-sectional study. Clin Biomech (Bristol, Avon) 2021; 84:105344. [PMID: 33798840 DOI: 10.1016/j.clinbiomech.2021.105344] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 03/12/2021] [Accepted: 03/23/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Dual-task paradigms allow to establish a relationship between motor and cognitive performance. The attentional resources needed to accomplish dual-tasks are influenced by age and task complexity. We investigated the dual-task costs for center of pressure displacement following manipulated motor and cognitive tasks in children, adolescents and young-adults. METHODS Thirty children, 24 adolescents and 32 young-adults performed motor (postural stability) and cognitive (arithmetic) tasks under single and dual-task conditions. Complexity was manipulated by changing the base of support (standard, narrow, standard_on_foam, narrow_on_foam) for motor tasks and the difficulty level of cognitive tasks via serial subtraction (by 5 and by 3). Dual-task costs were calculated based on area and velocity of center of pressure. FINDINGS Dual-task costs based on area during easy cognitive tasks were lower for children than young-adults. Under all the cognitive conditions, dual-task costs were lower on narrow than on standard bases of support. For all the tested bases of support, dual-task costs based on velocity were lower for more complex cognitive tasks than for easy tasks. INTERPRETATION In children, more than in adults, dual-task demanded central adaptations which increased area of center of pressure displacement. Mechanical reasons, which might limit the increase in center of pressure displacement when dual-tasking, may explain the lower dual-task costs in narrow bases compared to standard ones. Possibly, high cognitive demands may lead the participants to prioritize the motor task to keep balance, resulting in smaller increases in center of pressure displacement velocity during dual-task when compared to easier cognitive tasks.

Abstract
BACKGROUND Postural stability requires attentional resources. Dual-task paradigms are used to investigate the attentional demand of the studied tasks. However, no studies have been conducted on the subjects' level of attention, analyzing its association with dual-task costs (DTC). RESEARCH QUESTION To evaluate the attentional level and DTC on postural sway and cognitive yield in children, adolescents, and young adults, investigating age-related differences, and to analyze if the participants' attention level is associated with DTC. METHODS Postural sway and cognitive-yield of 30 children, 24 adolescents, and 32 young adults were assessed in a dual-task paradigm. We calculated DTC on postural sway and cognitive yield. Attention level was tested using Psychological Battery for Attention Assessment. We tested the association between DTC and attention level. RESULTS Young adults showed higher DTC on area and velocity of postural sway than children and adolescents. No differences in DTC on cognitive yield were found between the groups. Children showed lower attention levels than adolescents and young adults. Attention level was negatively associated with DTC on cognitive yield in young adults. Focused Attention is responsible for 24.4% of the variance in DTC on cognitive yield. CONCLUSION Age impacts DTC on postural stability, but not on cognitive performance. The smaller changes in sway found in children/adolescents when dual-tasking, potentially reflect less developed attentional levels and postural control, which make them performing postural tasks closed to their stability boundaries, and, therefore, make them prioritize stability protection more than adults. Similar DTC on cognition between groups may reflect an equalization of the chosen cognitive task at everyone's difficulty level. The lower attention levels of children may reflect an attentional system in development, with prioritization o postural tasks when dual-tasking to maintain stability. Although attention level increases throughout age, attention only predicted DTC on cognition. Better Focused Attention's levels predicted lower DTC on cognitive yield for young adults.

Abstract
BACKGROUND To verify the effect of dual-task on postural oscillation during sit-to-stand movement in children with Cerebral Palsy. METHODS 17 children with spastic unilateral cerebral palsy and 20 typically-developing children, aged 5 to 12 years, performed the following tasks: Simple task: sit-to-stand with arms crossed against the chest; bimanual dual-task: sit-to-stand while carrying a tray; unimanual dual-task: sit-to-stand while holding a plastic cup with one hand. For data analysis, sit-to-stand was divided in three phases: preparation (phase 1), rising (phase 2), and stabilization (phase 3). Postural control was measured using a force plate, and the variables analyzed were: area, anterior-posterior and medial-lateral velocity, and STS duration. Analysis of variance was applied to test the effects of group; task conditions and interactions. FINDINGS Children with cerebral palsy presented higher values of postural oscillation when compared to their typical pairs. Bimanual and Unimanual dual tasks presented greater postural oscillation values in sit-to-stand phase 1 compared to simple task. In bimanual dual-task, children with cerebral palsy presented lower values of velocity in phases 3, and greater postural oscillation and duration of the task when compared to single-task and unimanual dual-tasks. I. INTERPRETATION The insertion of a secondary task seems to interfere differently children with cerebral palsy, depending on the specific demands of each task. Thus, the importance of inserting dual tasks in the interventions is emphasized, considering that they are executed extensively in the day to day, and can act as facilitators or challenge in the execution of functional tasks.

Abstract
Aim: Children with cerebral palsy (CP) have difficulties performing activities that require the use of fundamental motor skills such as sit-to-stand (STS). In this study, we used a height adjustable chair and desk to investigate the role of desk support in STS and how it might benefit children with CP. Methods: Seventeen typically developing children (TDC), average age = 9.7 years, and 28 children with CP (Gross Motor Function Classification System [GMFCS] I and II), average age = 10.3 years, participated in the test. Elapsed time and body sway were measured using a pressure mat and load cell while each child performed a STS task. Two different desk heights were tested for time consumption and sway under the condition of hands-on-desk and arms-crossed. Results: We found that the elapsed time of hands-on-desk with the elbow flexion height was the shortest (p < 0.05). Sway amount was also significantly reduced for all children when they used the table for STS (p < 0.05). Conclusion: Results of this study may be a useful reference in rehabilitation training and designing a desk height beneficial for children with CP.Implications for RehabilitationBetter performance of sit-to-stand for a child with cerebral palsy could be made by a desk supportElapsed time during preparation period for sit-to-stand could be reduced by desk support for all CP childrenSway amount during sit-to-stand could be reduced by desk support, especially for the CP children with GMFCS level IIDesk height is an important parameter and should be studied in detail.

JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2019; 63:576-586. [PMID: 30687997 DOI: 10.1111/jir.12599] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Revised: 01/08/2019] [Accepted: 01/08/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Cognitive and postural tasks require common cognitive mechanisms, resulting in conflicts when both tasks are simultaneously performed. The presence of neuromotor dysfunctions, such as Down syndrome, may impair coordination processes required to perform dual-tasks. The objective of this study was to investigate the dual-task effects on postural sway during sit-to-stand movements in typical children and children with Down syndrome in a cross-sectional study. METHODS Twenty six typical children (10.2 ± 2.4 years) and 21 with Down syndrome (10.3 ± 2.3 years) performed sit-to-stand in the following conditions: (1) simple task; (2) dual-task bimanual activity (DT-Bim): sit-to-stand while carrying a tray using both hands; (3) dual-task unimanual dominant activity (DT-Uni-Dom): sit-to-stand while holding a plastic cup simulating water using the dominant hand; (4) dual-task unimanual non-dominant activity (DT-Uni-Nondom): sit-to-stand movement while holding a plastic cup simulating water. For data analysis, sit-to-stand was divided into three phases: preparation (phase 1), rising (phase 2), and stabilisation (phase 3). The following variables were calculated for each phase: anterior-posterior and medial-lateral amplitude of centre-of-pressure displacement, anterior-posterior and medial-lateral velocity of centre-of-pressure sway and area of centre-of-pressure sway. RESULTS Children with Down syndrome showed greater sway than typical children in all sit-to-stand phases. Typical children showed greater anterior-posterior amplitude in phase 2 of sit-to-stand during DT-Uni Nondom compared with DT-Uni Dom. Children with Down syndrome during simple task condition showed greater and faster values sway in phases 2 and 3 of sit-to-stand movement than in DT-Bim activity, DT-Uni Dom activity and DT-Uni Nondom activity. During the condition of DT-Bim activity, these children showed lower anterior-posterior velocity of sway in phase 2 than during DT-Uni Dom activity. CONCLUSIONS Children with Down syndrome showed greater postural sway during sit-to-stand than typical children. The addition of a concurrent motor task to sit-to-stand impacted postural sway in different intensities and in different ways across groups. Dual-tasks increased body sway in typical children in the DT-Uni Nondom condition compared with dominant one. In children with Down syndrome, dual-tasks decreased body sway, apparently resulting in a postural strategy of stiffness.
