Brief summary
We want to see whether it is convenient and practical for office-based workers to use the dome device regularly throughout the working day to improve blood flow through their legs while they are sitting down. We know that people sitting down for long periods of time (like when they are flying long distances, or in desk-bound role), may be at increased risk of developing blood clots called deep vein thrombosis (DVT) in their legs. This risk might be partly due to pooling of blood in the leg during long periods of sitting. Using the dome device every so often may help reduce pooling by improving the return of blood from the legs when used. To see if it’s practical to use the dome device in the workplace we would like to run a trial of approximately 200 office and call centre-based people using the device over the course of their working week. If we can show that the dome device is convenient, safe and practical, we may be able to introduce it as a simple office tool for people to help reduce the risk of developing blood clots when they are sitting down for long periods of time.
Interventions
Floor-based footrest.
This is a small device, approximately 300mm in length, with two raised domes. Viewed from the front it looks like a letter m. Users will flex and extend the soles of their feet over the humps. This is expected to improve blood flow from the legs back to the heart even while the users are seated.
After informed consent, the volunteers will each be given a floor-based dome device and shown how to use it throughout the working week. Participants in this study will be asked t
Floor-based footrest. This is a small device, approximately 300mm in length, with two raised domes. Viewed from the front it looks like a letter m. Users will flex and extend the soles of their feet over the humps. This is expected to improve blood flow from the legs back to the heart even while the users are seated. After informed consent, the volunteers will each be given a floor-based dome device and shown how to use it throughout the working week. Participants in this study will be asked to utilise the device for a minimum of 30 to 60 seconds every hour regardless of how long they may have been sitting down or how much they may have been walking in the office throughout the day. Participants will be given a diary in which to document their device usage (time of day it was used, duration of use and whether they had shoes on or off) each day. At the end of the week they will also be asked to rate how convenient they found the device, how easy and comfortable it was to use and how likely they would be to use it regularly throughout their working days in the future. These rating will be measured on a scale of 1 (very convenient / easy / comfortable / likely to use it again) to 4 (very inconvenient / very hard / very comfortable / definitely not likely to use it again). They will be asked to note down any adverse events associated with the device in the workplace. A free text space will be provided to note down any other thoughts or concerns about the device.
