There are many reports that low-intensity pulsed ultrasound (LIPUS) promotes fracture healing. However, to obtain sufficient therapeutic effect, appropriate use of LIPUS is necessary and patient compliance is very important for that. We reported at this meeting in 2014 about explanation for patients with leaflets, aiming at improvement of compliance. A new model on which calendar function was installed and the implementation rate (actual irradiation days/LIPUS borrowed days) could be clearly indicated has been available since February 2016. In this study, we investigated if the use of the leaflet is meaningful for improving compliance with this new model.Materials and Methods:
The subjects were 30 patients who underwent LIPUS at our hospital from April 2016 to March 2017 and were followed up for more than 3 months. The subjects consisted of 15 males and 15 females and the average age was 47.4 years (10–78 years) old. We examined compliance both in the group of 11 cases using the new model with explanatory leaflets and in the group of 19 cases using the new model without leaflet explanation.Results:
The average compliance rate of all patients was 83.2% (37.6%–100%). The average rate was 88.8% in the group with explanatory leaflet and 79.9% in the group without the leaflet (P = 0.11).Discussion:
Pounder et al reported that the implementation rate was significantly improved by using the new model, indicating the usefulness of the new device. The result of this study suggested that further improvement of compliance could be expected by using the new model and explanatory leaflets.
