## 4 Discussion
The first study limitation is the lack of documentation of the self-practice time of the control group. Although they reported that they practiced at home, there was a low response in filling out the self-practice documentation form provided to them. Considering the lack of documentation for self-practice and the higher number of sessions received by the tele-rehabilitation group in the first month of intervention, it might be possible that one group practiced more than the other. This factor might have affected our results. Future studies might therefore strive to compare two groups who received an equal number of sessions and self-practices. This might prove challenging, as the low compliance of individuals with elbow injuries to arrive at the clinic would force the researchers to limit the tele-rehabilitation sessions, thereby restricting the treatment of the tele-rehabilitation group. Second, a large sample size is needed. Last, the PREE and DASH questionnaires relate to some functions that may have been performed in the dominant hand before the injury. Since two thirds of the subjects in each group were injured in their nondominant hand, their scores might have been underestimated. However, as shown by [45], the slight effect of the side of injury on the DASH score is lower than the minimally important difference. In conclusion, since tele-rehabilitation is a cost-effective treatment suitable for patients with accessibility difficulties or who have difficulty in arriving at the clinic, we conclude that it could be incorporated in the framework of treatment following elbow fractures, as its outcome measures are not different from those acquired during traditional treatment.

P values were calculated separately for each group using the Friedman test. Where statistical significance was found, the Wilcoxon post hoc test was applied.
