Wearable Devices in Asthma |
T113 |
27-205 |
Sentence |
denotes |
Most of the wearable fitness device research to date has focused in diseases associated with low levels of physical activity, namely cardiovascular disease, diabetes, and cancer. |
T114 |
206-369 |
Sentence |
denotes |
Few have focused on asthma and of the studies conducted in asthma populations, all have honed in on the use of Fitbit-derived sleep measures (i.e., sleep quality). |
T115 |
370-464 |
Sentence |
denotes |
Castner et al. used the Fitbit Charge™ to validate sleep measures in women with asthma [18••]. |
T116 |
465-614 |
Sentence |
denotes |
The sleep measures collected by the Fitbit were compared with Actigraph GT3X +, a well-known and validated device to collect sleep measures [19, 20]. |
T117 |
615-728 |
Sentence |
denotes |
The Fitbit device tended to overestimate sleep efficiency and underestimate wake counts compared with actigraphy. |
T118 |
729-928 |
Sentence |
denotes |
Two additional studies were conducted in pediatric populations and focused on correlating Fitbit-derived sleep measures to patient-reported outcomes such as asthma control and asthma impact [21, 22]. |
T119 |
929-1204 |
Sentence |
denotes |
Bian and colleagues assessed the association between self-reported asthma impact and Fitbit-derived sleep quality (the ratio of minutes asleep to minutes in bed) and physical activity measures (daily minutes of moderate and vigorous activity) in adolescents with asthma [21]. |
T120 |
1205-1498 |
Sentence |
denotes |
Fitbit-derived sleep quality was moderately correlated with Patient-Reported Outcomes Measurement Information System (PROMIS) sleep disturbance score (r = − 0.31, P = 0.01) and had a weak but significant correlation with the PROMIS pediatric asthma impact score (average r = − 0.18, P = 0.02). |
T121 |
1499-1616 |
Sentence |
denotes |
Fitbit-derived physical activity levels were not associated with PROMIS pediatric asthma impact (r = 0.04, P = 0.62). |
T122 |
1617-1806 |
Sentence |
denotes |
These findings suggest that measurement of sleep quality, using the Fitbit device, may help develop personalized asthma management strategies for children and their caregivers in real time. |
T123 |
1807-2189 |
Sentence |
denotes |
The final study measured several mobile metrics of asthma including physical activity and sleep using Fitbits, forced expiratory volume in 1 s and peak expiratory flow, indoor air quality using Foobot (https://foobot.io/), and a mobile app that collected information on asthma control (symptoms, physical limitations due to asthma, nighttime awakenings, and medication intake) [22]. |
T124 |
2190-2437 |
Sentence |
denotes |
These metrics were used together to digitally phenotype children with asthma and provide a better measure of the patient’s asthma control to their clinician when compared with the Asthma Control Test scores taken infrequently during clinic visits. |
T125 |
2438-2661 |
Sentence |
denotes |
Additional work using this ecological metric of asthma control is needed and may be used in the future to generate insights on the relationship between a patient’s asthma symptoms and triggers across different seasons [23]. |
T126 |
2662-2750 |
Sentence |
denotes |
Acoustic monitoring is another type of wearable devices that has been studied in asthma. |
T127 |
2751-2936 |
Sentence |
denotes |
Breathing sound measured by microphones over human skin can detect breathing patterns (respiratory rate, flow rate, tidal volume) and symptoms that may be due to asthma (wheeze, cough). |
T128 |
2937-3040 |
Sentence |
denotes |
Moreover, chest movement signals can be acquired using an accelerometer or belt-shaped device [24, 25]. |
T129 |
3041-3146 |
Sentence |
denotes |
Boner et al. measured the nocturnal wheeze in children with asthma using an acoustic respiratory monitor. |
T130 |
3147-3331 |
Sentence |
denotes |
They found that among children with apparently well-controlled asthma, 57% had considerable amounts of night wheezing that was unrelated to conventional measures of lung function [26]. |
T131 |
3332-3463 |
Sentence |
denotes |
The use of these continual wearable monitoring systems is still a developing field that needs further study on its clinical impact. |
