Abstract EN
The aim of the study was to determine the effect of different muscle length and visual feedback information (VFI) on accuracy of isometric contraction of elbow flexors in men after an ischemic stroke (IS).
Materials and Methods.
Maximum voluntary muscle contraction force (MVMCF) and accurate determinate muscle force (20% of MVMCF) developed during an isometric contraction of elbow flexors in 90° and 60° of elbow flexion were measured by an isokinetic dynamometer in healthy subjects (MH, n = 20 ) and subjects after an IS during their postrehabilitation period (MS, n = 20 ).
Results.
In order to evaluate the accuracy of the isometric contraction of the elbow flexors absolute errors were calculated.
The absolute errors provided information about the difference between determinate and achieved muscle force.
Conclusions.
There is a tendency that greater absolute errors generating determinate force are made by MH and MS subjects in case of a greater elbow flexors length despite presence of VFI.
Absolute errors also increase in both groups in case of a greater elbow flexors length without VFI.
MS subjects make greater absolute errors generating determinate force without VFI in comparison with MH in shorter elbow flexors length.
