Limitations
BLIND
During the pilot, we adapted the original protocol to remove assessments on the Lysholm Knee Score and Single leg hopping test. It was believed that this deviation from the protocol was justified. The primary reasons for the change were some of the participants were unable to complete the jumping movement of the operated leg and the IKDC questionnaire was more sensitive and responsive to changes in knee function after ACL reconstruction [We did not blind participants or providers. This is because the limbs were relatively sensitive to changes in pressure levels. In addition, the providers needed to set the appropriate parameters for the participants according to their grouping and through the device. Furthermore, it is imperative to acknowledge the potential impact of the lack of blinding of outcome assessors on the study’s results. One limitation could be that the assessment of the outcomes may not be standardized across all participants due to the variability in the perception of the outcome assessor.Because of this study’s small sample size, there was a chance of Type I error which is the mistaken rejection of a null hypothesis as the result of a test procedure, and Type II error which is the mistaken failure to reject the null hypothesis as the result of a test procedure. For example, one individual making a large gain would lead to this. In this situation, the IKDC and YBT statistics may not be scientific enough as indicators (power < 0.8).
