Introduction/Background Trunk muscular function has been identified as an early predictor of health-related outcomes post-stroke, revealing unbalance on both sides changing muscular response in the axis of the body. Then, we aimed to compare the isokinetic measures of strength and endurance for trunk movement in antagonistic actions (flexion and extension), starting from the two different methods of assessment (seated compressed [SC] and semi-standing [SS]) for groups of able-bodied (control) and post-stroke hemiparesis (hemiparesis) people. Material and method A cross-sectional case-control study design was performed to compare strength (peak toque and normalized peak torque) and endurance (muscular power and total work) variables took at 60° and 120°/seconds, respectively, from the four observed conditions for a convenience sample composed by 26 volunteers (13 participants by group). The Functional Independence Measurement (FIM), the modified Ashworth Scale (mAS) and Mini Mental State Examination (MMSE) were the secondary variables to characterize the sample. Significant differences were detected by the two-way ANOVA followed by the Bonferroni post-test (P  Results For both groups and in all conditions, the extensor muscles performed around the doubled value recorded from all variables when compared to flexor muscles. Hemiparesis group revealed the expected weakness in comparison with control group, manifesting significant more strength and endurance when assessed by SS method, what was not observed in the control group. Conclusion In conclusion, our results suggested that trunk extensor muscles are naturally stronger than flexor and post-stoke hemiparesis people are favored by SS method during isokinetic assessment.
