Six Minutes Walk Test in Children on Regular Hemodialysis

Not yet recruiting

• Conditions: Hemodialysis

• Registration Number: NCT06910319
• Lead Sponsor: Assiut University

Brief Summary

To evaluate exercise tolerance and the reproducibility of the six minute walk test in children and adolescents with ESRD on regular hemodialysis and to compare their functional exercise capacities with reference values for healthy children. To investigate predictors of poor 6MWT performance in children on regular HD

Detailed Description

The six-minute walk test (6MWT) is a submaximal test that assesses the functional exercise capacities of healthy subjects or those with a chronic disease, as well as the effects of interventions, such as pulmonary rehabilitation or drug therapies. It can predict prognosis, mortality and morbidity in adults and children with lung and/or heart diseases . A study with of children with stage V chronic kidney disease (CKD) has used the 6MWT to demonstrate decreased exercise tolerance , which appears to be caused by several factors, such as anemia, metabolic acidosis, electrolyte imbalance, osteopenia, growth deficiency, malnutrition, inactivity, uremic muscle dysfunction and associated comorbidities . The findings of this study suggest that the 6MWT could be used as a clinical tool to monitor functional exercise capacity in children with kidney disease. The 6MWT is a sub-maximum effort test that is more representative of daily life activities than other effort tests and has low cost and easy applicability . The distance walked in the 6MWT shows an association with VO2 peak, making it a viable and safe alternative for patients who cannot tolerate the ergometric test .
