Highlights
- •A randomised pilot trial amongst adults with Cystic Fibrosis
- •Intervention consisted of wearable technology, goal setting and text message feedback
- •Active comparator group wore wearable technology only
- •Physical activity increased for both groups
- •Text messages based on collaborative goal setting showed significantly greater improvements
Abstract
Background
Regular participation in physical activity (PA) is encouraged for people with Cystic
Fibrosis (CF). This study aimed to assess the effectiveness of an intervention using
wearable technology, goal setting and text message feedback on PA and health outcomes
in people with CF.
Methods
This was a pilot randomised trial conducted at University Hospital Limerick. Participants
were randomly assigned to the intervention (INT) or active comparator (AC). The 12-week
intervention consisted of wearable technology (Fitbit Charge 2) which was remotely
monitored, and participants set step count goals. Participants were sent a one-way
text message once a week over 12 weeks to positively reinforce and encourage PA participation.
The AC group received the wearable technology alone. Follow up was assessed at 24
weeks. Outcomes assessed were PA, aerobic capacity, lung function, sleep, quality
of life and wellbeing.
Results
Step count increased significantly for the INT group over 12 weeks when compared to
the AC group (p=0.019). The INT group had a 28% week-to-week percentage change (Weeks
1-12), while the AC group reduced by 1%, p=0.023. Within group changes demonstrated
that VO2 peak (ml/kg/min) significantly increased for the INT group at 12 weeks (24.4
±7.65 to 26.13 ±7.79, p=0.003) but not at 24 weeks (24.45 ±7.05, p=0.776). There were
no significant differences observed for VO2 peak (ml/kg/min) for the AC group. There
was no significant effect on lung function, sleep, well-being, or quality of life
for either group.
Conclusions
A personalised PA intervention using wearable technology, goal setting and text message
feedback increased PA and aerobic capacity in people with CF. Integration of this
intervention into usual care may encourage regular PA participation for people with
CF.
