Effects of Paediatric Post-COVID-19 Condition on Physical Function and Daily Functioning: A Cross-Sectional Study

Area of Science:

• Pediatric Health
• Infectious Diseases
• Rehabilitation Medicine

Background:

• Limited objective data exists on physical function and daily life impact in pediatric post-COVID-19 condition (PPCC).
• Assessing exercise capacity, muscle strength, and fatigue is crucial for understanding PPCC's long-term effects.

Purpose of the Study:

• To evaluate exercise capacity, peripheral and respiratory muscle strength, and fatigue in children with PPCC.
• To compare these parameters between PPCC patients and healthy controls.
• To determine the impact of PPCC on children's daily functioning.

Main Methods:

• A cross-sectional study design was employed.
• Key assessments included the 6-minute walk test (6MWT), maximal inspiratory pressure (PImax), handgrip strength (HHD), and muscle thickness/area via ultrasound.
• Fatigue was measured using the pediatric Functional Assessment of Chronic Illness Therapy-Fatigue (pedsFACIT-F), and physical activity with the Assessment of Physical Activity Levels Questionnaire (APALQ).

Main Results:

• Children with PPCC demonstrated significantly lower exercise capacity (6MWT), respiratory muscle strength (PImax), and handgrip strength compared to controls.
• PPCC patients reported higher levels of fatigue (pedsFACIT-F) and reduced physical activity (APALQ).
• Significant limitations were observed in daily activities, with many children unable to participate fully in sports, school, or after-school activities.

Conclusions:

• Pediatric post-COVID-19 condition is associated with substantial impairments in physical function and significant negative impacts on daily life.
• These findings underscore the necessity of developing targeted therapeutic strategies for children affected by PPCC.
• Further research is warranted to explore the underlying mechanisms and optimize rehabilitation approaches.
