Strengths and Limitations
Firstly, there were some problems when collecting data on postural sway with the IMU device. The device did not show when it was fully charged, and, therefore, it sometimes turned out to be uncharged at the time of data collection. Moreover, the instructions for standardizing the measuring procedure were not clear enough, which limited our results on postural sway. Moreover, due to the lack of data on compliance rate, we did not know if the intervention groups received more training sessions than the control group or the compliance rate. We did not have information regarding the pre-fracture function of the participants.In this study, we lack qualitative information about how the participants and the PT perceived the intervention. The User Satisfaction Evaluation Questionnaire (USEC) is designed to be answered by a user of technology. In our study, the physiotherapists were the users, but the final workshop with the physiotherapists revealed that they considered USEC to be irrelevant, and, thus, they had not filled it in. Therefore, there were no data from USEC to analyze. We consider the RCT design and the individualized but controlled exercise program as strengths of this study since the program was easy to adjust to each individual’s progression.
