Outcome measures
Primary outcome
A scale correlating the increase in muscle activity to the gold standard determination of asthma severity
Secondary outcome
Accuracy and reproducibility of EMG signals in children
Breathing patterns after exercise scaled to the severity of asthma
Cardiac activity after exercise scaled to the severity of asthma
Background summary
Asthma is a chronic disease affecting about 10% of children in the Netherlands. The current method of determining childhood asthma consists of an extensive exercise challenge test. Whilst precise, the tests are expensive and time consuming. Electromyography recorded with a wearable device provides additional information and may in the future be used to assess children outside of the hospital in more life-like situations. This study aims to prove EMG is a viable tool in assessing childhood asthma, by comparing the outcome parameters with the current gold standard. If EMG proves feasible, this makes way for further research in this population.
Study objective
An increase of diaphragmatic and accessory breathing muscle activity is an indicator for the severity of childhood asthma.
Study design
-3 weeks before exercise challenge test: recruitment of patients
-2 weeks before exercise challenge test: patient information forms sent to patients and parents
Just before exercise challenge test: signing informed consent forms, applying measurement equipment
Measurement runs until end of exercise challenge test
Intervention
Electromyography recording
