Abstract:
Objective To evaluate quantitatively the spasticity of elbow flexor biceps in stroke patients using integrated EMG (IEMG),and to correlate the IEMG with Ashworth scale.Methods The IEMG data was recorded from the biceps while passively stretch the elbow joint of a group of 90 subjects,and was correlated with the varying levels of Ashworth category(20 cases with grade 0,6 cases gradeⅠ,16 cases gradeⅠ~+,20 cases gradeⅡ,and 18 ca- ses gradeⅢ).Results The IEMG data were positively correlated with simultaneous Ashworth scale categories.The range of IEMG value corresponding to the Ashworth category is as follows:1.3～12.1 (6.7?5.4)?V?s vs Ash- worth grade 0;4.6～12.3 (8.5?3.9)?V?s vs Ashworth gradeⅠ.15.3～28.4(21.8?6.6)?V?s vs Ashworth gradeⅠ~+;37.2～68.9 (53.1?15.6)?V?s vs Ashworth gradeⅡ;82.3～144.1 (113.2?30.9)?V?s vs Ash- worth gradeⅢ.Conclusion The IEMG value can be used to quantify the spasticity of elbow flexor in stroke pa- tients.
