=================
Brief Summary
-----------------
studying the relationship between Bone Mineral Density, Gross Motor Function and, Quality of Life with CP can provide valuable insights into the musculoskeletal consequences of motor impairments and guide interventions to improve bone health. Statement of the problem Is there a relation between Bone Mineral Density, Gross Motor Function and Quality of Life in children with CP ? Purpose of the study To study the relationship between: Bone Mineral Density and Gross Motor Function in ambulant and non-ambulant CP children. Bone Mineral Density and Quality of Life in ambulant and non-ambulant CP children. Gross Motor Function and Quality of Life in ambulant and non-ambulant CP children.

Detailed Description
-----------------
Cerebral palsy (CP) is primarily a neuromotor disorder that affects the development of movement, muscle tone and posture. The underlying pathophysiology is an injury to the developing brain in the prenatal through neonatal period. Although the initial neuro pathologic lesion is non-progressive, children with cerebral palsy may develop a range of secondary conditions over time that will variably affect their functional abilities. The prevalence of CP varies between 1.5 to more than 4 cases per 1,000 live births worldwide. The motor impairments associated with CP can range from mild to severe, affecting different muscle groups and leading to difficulties in activities of daily living and participation in social and recreational activities. Children with CP often experience motor impairments that affect their gross motor function, leading to limitations in activities and participation. These motor impairments can also have a negative impact on bone health, resulting in reduced bone mineral density (BMD) and increased risk of skeletal complications. Gross motor function (GMF) refers to the ability to perform coordinated movements using large muscle groups, such as walking, running, and jumping. It is a key aspect of physical ability and independence in daily activities for children with CP. Previous research has shown that gross motor function is closely associated with bone health in this population. However, further investigation is needed to explore the specific nature of this correlation and its implications for intervention strategies. Gross motor function is commonly assessed using standardized tools such as the Gross Motor Function Classification System (GMFCS) or the Gross Motor Function Measure (GMFM). Quality of life is a multidimensional construct that encompasses physical, psychological, and social well-being. In the context of cerebral palsy, understanding the impact of gross motor function on quality of life is crucial for comprehensive care and intervention planning. Children with CP may face limitations in mobility, participation in activities, and social interactions, which can significantly affect their overall quality of life. Exploring the relationship between gross motor function and quality of life can provide valuable insights into the factors influencing the holistic well-being of children with CP. The quality of life in children with CP is not only influenced by their motor function but also by their overall health and well-being. Bone health plays a crucial role in maintaining the physical abilities and independence of individuals, as well as their overall quality of life. Impaired bone health in children with CP can lead to limitations in mobility, increased pain, and reduced participation in activities, which can have a significant impact on their overall well-being. Bone mineral density, on the other hand, is an important measure of bone strength and overall skeletal health. Children with CP often exhibit lower BMD compared to typically developing peers due to factors such as reduced weight-bearing activities, muscle weakness, altered biomechanics, limited mobility, and hormonal imbalances. This reduced BMD increases their susceptibility to fractures and skeletal deformities, further impacting their functional abilities and quality of life.
