Keywords

Cystic Fibrosis, Urinary Incontinence, Dyspnea, Muscle Strength, Quality of Life, Exercise Test

Brief summary

It is aimed to reveal impairments regarding urinary incontinence, dyspnea, muscle strength, functional capacity or quality of life in children and adolescents with cystic fibrosis compared to healthy children and adolescents.

Detailed description

This study aims to compare dyspnea, functional capacity, muscle strength, urinary incontinence and quality of life between children and adolescents with cystic fibrosis and healthy children and adolescents. Participants will be assessed for these parameters through clinical evaluations, exercise tests, questionnaires and measurements. The study aims to understand the health implications of cystic fibrosis and provide the basis for improvements in the health management of these individuals.

Interventions

OTHERPhysical Evaluations in Children with Cystic Fibrosis

In this study, dyspnea, functional capacity, muscle strength, urinary incontinence and quality of life will be evaluated in children and adolescents with cystic fibrosis. The data to be obtained through all these evaluations will be done face to face within 45-60 minutes.

In this study, dyspnea, functional capacity, muscle strength, urinary incontinence and quality of life will be evaluated in healthy children and adolescents. The data to be obtained from all these assessments will be made face to face within 45-60 minutes.

Design outcomes

Primary

MeasureTime frameDescription
Hand Grip Strengththrough study completion, an average of 1 yearGrip strength will be measured using a dynamometer. Each hand will be tested three times, and the highest value will be recorded for both sides.

Secondary

MeasureTime frameDescription
Dyspnea scorethrough study completion, an average of 1 yearDyspnea will be assessed with the Modified Medical Research Council (MMRC) Dyspnea Scale, scored from 0 (no dyspnea) to 4 (maximum severity).
Pulmonary Function Test Evaluationthrough study completion, an average of 1 yearLung function will be assessed with a spirometer. The highest value of the three measurements will be used and interpreted according to gender, age, weight and height. A value below 80% of the expected value will be interpreted as abnormal.
Respiratory Muscle Strength Evaluationthrough study completion, an average of 1 yearRespiratory muscle strength will be assessed with a spirometer. The test will be conducted with the participant seated, using a mouthpiece and a nose clip. The highest value for inspiratory and expiratory pressure will be recorded. A value below 80% of the expected value will be interpreted as abnormal.
Cough Strength Evaluationthrough study completion, an average of 1 yearThe peak cough expiratory flow of the individual will be assessed using a peak flow meter. The best of at least three repetitions is recorded.A value above 450 indicates effective cough.
Aerobic Exercise Capacity Evaluationthrough study completion, an average of 1 yearAerobic capacity will be assessed twice via 6-minute walk test. The longest distance will be used for analysis. A value below 80% of the expected value will be interpreted as abnormal.
Anaerobic Exercise Capacity Evaluationthrough study completion, an average of 1 yearAnaerobic capacity will be assessed via the 3-minute step test (3-STT). For the 3-STT, participants will rest for 10 minutes before performing the test with a 15 cm step at a rate of 30 steps per minute, controlled by a metronome. The total number of steps will be recorded.A high number of steps indicates good capacity.
Quality of Life Scorethrough study completion, an average of 1 yearThe scale we will use to assess health-related quality of life, the Pediatric Quality of Life Inventory (PedsQL 4.0). The scale was developed to assess the health-related quality of life of children and adolescents between the ages of 2 and 18 and consists of physical, emotional, social and school functioning items, totaling 23 items.Scores from this questionnaire are converted to a scale of 0 to 100. Higher scores indicate better health-related quality of life.
Urinary incontinence scorethrough study completion, an average of 1 yearUrinary incontinence will be assessed using the Voiding Dysfunction Symptom Score, a 15-item questionnaire. A score above 8.5 indicates the presence of lower urinary tract symptoms.
