How can wrist sensors aid clinical trials with PH children?
“Wrist sensors reveal physical activity gaps for children with PH in study,” by Marisa Wexler, MS, discusses how the findings may help develop metrics for use in clinical trials with kids.
At first, I felt annoyed because the findings seem to be stating the obvious: “Children with pulmonary hypertension (PH) engage in fewer and shorter bouts of intense physical activity than their peers, according to a new study that measured data from sensors worn on the wrist.” My son was diagnosed with PH when he was 8, and I did not need a wrist sensor to tell me this, but as I continued reading, I began to understand the potential benefits of this technology.
The 6-minute walk test is limited because, depending on how the patient is feeling that day, it may not accurately reflect the patient’s physical ability. As the article points out, this test is even harder to rely on for children.
“The results showed that overall physical activity was similar in the children with and without PH. However, differences were evident when the researchers looked at the intensity of physical activity.”
I don’t think the wrist sensors should replace the 6-minute walk, but they should be included to assess a PH child’s normal day-to-day activity, and if they provide information that helps trials, even better.
What are your thoughts?
