The aims of this study were to compare the normal values of the isokinetic dynamometer pendulum test and those of the electrogoniometric one, to compare the relaxation indices of the isokinetic dynamometr pendulum test and those of the
electrogoniometric one according to modified Ashworth scale. to identify the critical value of the relaxation index of the isokinetic dynamometer pendulum test according to modified Ashworth scale, to identify the correlation of modified Ashworth
scale
with the pendulum test, and to identify the correlation of Brunnstrom stage with the pendulum test in the 77 hemiplegic patients with varing degrees of spasticity.
@ES The results were:
@EN 1) The relaxation index, amplitude ratio, swing number, and swing time of the isokinetic dynamometer pendulum test were significantly lower than those of the electrogoniometric one in the control group.
2) The relaxation indices of the isokinetic dynamometer pendulum test were generally higher than those of the electrogoniometric one according to moditied Ashworth scale and Brunnstrom stage.
3) If the relaxation index was over 1.20, that modified Ashworth scale was considered as grade 1. But we could not estimate the range of the relaxation index of modified Ashworth scale 2 and 3.
4) Modified Ashworth scale was reversely correlated with the relaxation index of the isokintic dynamometr pendulum test and the electrogonicmetric one, but correlation coefficients were not so high.
5) The relaxation index of the pendulum test was not significantly different among the Brunnstron stages.
In the above study, modified Ashworth scale was reversely correlated with the relaxation index of the isokinetic dynamometer pendulum test, but corelation coefficients were not so high and the ranges of relaxation index were not clearly defined
according to modified Ashworth sclase. So, we thought that new measurement scale for evaluation of spasticity using pendulum test (especially, electrogoniometric pendulum test) was needed, but further study was also needed after collection of
more
samples.
