An experimental group (EG, n=15, with various injuries) and a healthy control group (CG, n=22) performed the same tests. Comparisons were made between the injured and healthy legs in the EG (%LSI) and between the injured leg in the EG and the dominant leg in the CG (%Norm-values).</p><p>This study followedthe principles of the Declaration of Helsinki (1964), and the national ethics committee for sports science research (CERSTAPS n°IRB00012476-2020-24-03-48) approved all methodology of this study.</p><p class="ql-align-justify">The Shapiro-Wilk test was used to check the normality of data distribution. Repeated measures (RM) ANOVAs included the method (3-levels: NV<sub>IL</sub>, NV<sub>NIL</sub> <em>vs</em> LSI) as the within subject factor were used for LSI<sup> </sup>and NV for injured and non-injured leg<sub> </sub>. Tukey <em>post-hoc</em> test assessed pairwise statistical differences between method conditions. The significance threshold was set at p<0.05. The effect sizes for mean values was determined by a Cohen's d (classified as trivial: <0.2, small: 0.2-0.49, medium: 0.5-0.79, and large: ≥0.8). </p><p>Post-rehabilitation, the LSI method showed mean kinetic values of 118%, while the Norm-Values method showed 87% for the injured leg and 98% for the non-injured leg. Combined EMG and kinetic values were 120% for LSI vs 88% for Norm-Values for the injured leg and 87% for the non-injured leg.</p><p class="ql-align-justify">The LSI method overestimated recovery compared to the Norm-Values method, which may be more accurate for post-injury assessment. If Norm-values are unavailable, LSI can be used with caution in interpreting results.</p><p><br></p> %I 4TU.ResearchData
