Investigation of Cardiopulmonary Parameters, Motor Development and Muscle Strength in DS With and Without CHD

Investigation of Cardiopulmonary Parameters, Motor Development and Muscle Strength in Children With Down Syndrome With and Without Congenital Heart Disease

Congenital heart diseases (CHD) are detected in 40-60% of individuals with Down syndrome (DS) and increase the risk of developmental delay in the presence of syndromes. The aim of the study was to compare cardiopulmonary parameters, gross motor development and hand grip strength in DS children with and without CHD. Demographic variables, cardiopulmonary parameters and echocardiographic values were recorded. Gross motor development was evaluated with Gross Motor Function Measure (GMFM-88). Hand grip strength was measured with the Baseline Pneumatic Bulb Dynamometer.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
with Congenital heart diseases	Diagnostic test: evaluation of cardiopulmonary parameters, gross motor development and hand grip strength; Gross motor development was evaluated with Gross Motor Function Measure (GMFM-88). Hand grip strength was measured with the Baseline Pneumatic Bulb Dynamometer. Cardiopulmonary parameters values was evaluated with echocardiography.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Gross Motor Function Measure-88	Gross motor development of the participants was evaluated with the Gross Motor Function Measure-88 questionnaire. The value as a percentage was obtained as a result of the survey. Gross Motor Function Measure-88 consists of 5 sections that include the evaluation of Lying & Rolling, Sitting, Crawling & Kneeling, Standing, Walking, Running & Jumping activities. Each item in the sections consists of a 4-point scale. Scores for each section are summed and divided by 5.The maximum score on the scale is 100. A high score indicates good gross motor development. 0 = does not initiate; = initiates; = partially completes; = completes	october 2020- june 2021
Bulb Dynamometer	Hand grip strength was measured with a Baseline Pneumatic Bulb Dynamometer (Fabrication Enterprises INC, Elmsford, NY USA). With a bulb dynamometer, the spherical grip force is measured using a rubber balloon tip. The bulb dynamometer has 3 removable sizes. The values measured on the manometer are recorded in kPa. The measurement is repeated 3 times and the highest value is taken.	october 2020- june 2021
Left ventricular ejection fraction (EF)	Echocardiographic findings performed in the last 6 months were evaluated by a pediatric cardiologist. It is obtained by dividing the difference in left ventricular volume at end-diastolic and end-systolic by the end-diastolic left ventricular volume. Left ventricular ejection fraction (EF) indicate the systolic function of the left ventricle. Ejection fraction value show as a percentage (%). The ejection fraction normal value is between 50 percent and 70 percent.	october 2020- june 2021
Interventricular septum wall thickness (IVS)	Echocardiographic findings performed in the last 6 months were evaluated by a pediatric cardiologist. It is important in the risk classification potential of left ventricular systolic function. Its value is show as millimeters (mm).	october 2020- june 2021
Left ventricular end-diastolic diameter (LVDd)	Echocardiographic findings performed in the last 6 months were evaluated by a pediatric cardiologist. It is important in the risk classification potential of left ventricular systolic function. Its value is show as millimeters (mm).	october 2020- june 2021
Fractional shortening (FS)	Echocardiographic findings performed in the last 6 months were evaluated by a pediatric cardiologist. Fractional shortening evaluates left ventricular systolic function. Fractional shortening value show as a percentage (%). The value of normal fractional shortening in children is between 28-44%.	october 2020- june 2021
Wang Respiratory Score	The Wang respiratory score assesses respiratory frequency, wheezing, retraction, and general condition. parameters are scored between 0-3 and summed. A higher score indicates that the situation is getting severe.	october 2020- june 2021
