ABSTRACT
Objectives: A group of neuromuscular system anomalies associated with non-progressive issues in the developing fetal or newborn brain are known as cerebral palsy (CP). These abnormalities are typified by poor posture and motor development, which limits the execution of functional activities. Consequently, to achieve the same goals as peers who are typically developing, children with CP employ a variety of compensatory postures and techniques. Given that both sitting and mobility are essential for functioning, assessing each skill alone and in relation to the other is necessary. This study aims to determine if a child's functional mobility affects their sitting ability. Materials and Methods: Twenty CP (Gross Motor Function Classification System [GMFCS] levels I and II) children, aged 6-12, were enrolled in the research. The level of sitting scale (LSS) and the modified timed up and go (mTUG) test were utilized to evaluate sitting and functional mobility, respectively. Results: The quality of sitting was shown to have a substantial effect on functional mobility, as a significant difference in mTUG durations was established between LSS levels (P < 0.001) and persisted when analyzed within the same GMFCS level (P = 0.007). Conclusion: The importance of trunk control in functional mobility can be inferred from the link between sitting quality and mobility. To improve children with CP's functional mobility, this evidence may be utilized to design a well-informed and specific intervention program incorporating trunk control.
ABSTRACT
BACKGROUND: Individuals with Down syndrome present with several impairments such as hypotonia, ligament laxity, decreased muscle strength, insufficient muscular cocontraction, inadequate postural control, and disturbed proprioception. These factors are responsible for the developmental challenges faced by children with Down syndrome. These individuals also present with balance dysfunctions. PURPOSE: This systematic review aims to describe the motor dysfunction and balance impairments in children and adolescents with Down syndrome. METHODS: We searched the Scopus, ScienceDirect, MEDLINE, Wiley, and EBSCO databases for observational studies evaluating the motor abilities and balance performance in individuals with Down syndrome. The review was registered on PROSPERO. RESULTS: A total of 1,096 articles were retrieved; after careful screening and scrutinizing against the inclusion and exclusion criteria, 10 articles were included in the review. Overall, the children and adolescents with Down syndrome showed delays and dysfunction in performing various activities such as sitting, pulling to stand, standing, and walking. They also presented with compensatory mechanisms to maintain their equilibrium in static and dynamic activities. CONCLUSION: The motor development of children with Down syndrome is significantly delayed due to structural differences in the brain. These individuals have inefficient compensatory strategies like increasing step width, increasing frequency of mediolateral center of pressure displacement, decreasing anteroposterior displacement, increasing trunk stiffness, and increasing posterior trunk displacement to maintain equilibrium. Down syndrome presents with interindividual variations; therefore, a thorough evaluation is required before a structured intervention is developed to improve motor and balance dysfunction.
