Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

'The PACT trial' is randomized pilot trial to demonstrate the feasibility and potential effectiveness of a personal "fitness tracker" to improve adherence to an activity regimen following an initial acute DVT in children.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The feasibility of an innovative intervention of a validated fitness tracker, the Fitbit, to improve adherence to a 12-week activity regimen in a pilot randomized controlled trial (RCT) will be tested in 44 subjects with first, acute, proximal lower extremity deep vein thrombosis (DVT).

The primary outcomes will consist of a) feasibility indicators determined a priori (eligibility, consent, adherence, retention) and b) estimates of effect size associated with the prescribed activity regimen, by describing within-subject change in QoL and potential biomarkers of postthrombotic syndrome (PTS) pre and post intervention in each group.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention

Participants randomized to the intervention arm will receive a Fitbit, formal 30-minute education session on post-thrombotic syndrome (PTS) and benefits of increased physical activity. An individualized activity prescription will be provided and participants will be asked to maintain the target level of activity for 12 weeks after determining their habitual activity in the first 4 weeks.

Group Type EXPERIMENTAL

Fitbit

Intervention Type DEVICE

The Fitbit will be utilized in the intervention arm to improve adherence to a 12-week activity regimen.

30-minute education session

Intervention Type BEHAVIORAL

Control

Participants randomized to the control arm will receive a formal 30-minute education session on post-thrombotic syndrome (PTS) and the benefits of increased physical activity. Their physical activity will be self-reported in an activity log and by the Gordin activity questionnaire over the 16-week intervention period.
