The pendulum test is a standard clinical test for quantifying the
severity of spasticity. In the test, an electrogoniometer is typically used to
measure the knee angular motion. The device is costly and difficult to set up
such that the pendulum test is normally time consuming. OBJECTIVE: The goal of
this study is to determine whether a Nintendo Wii remote can replace the
electrogroniometer for reliable assessment of the angular motion of the knee in
the pendulum test. METHODS: The pendulum test was performed in three control
participants and 13 hemiplegic stroke patients using both a Wii remote and an
electrogoniometer. The correlation coefficient and the Bland-Altman difference
plot were used to compare the results obtained from the two devices. The Wilcoxon
signed-rank test was used to compare the difference between hemiplegia-affected
and nonaffected sides in the hemiplegic stroke patients. RESULTS: There was a
fair to strong correlation between measurements from the Wii remote and the
electrogoniometer (0.513<R(2)<0.800). Small but consistent differences between
the Wii remote and electrogoniometer were identified from the Bland-Altman
difference plot. Within the hemiplegic stroke patients, both devices successfully
distinguished the hemiplegia-affected (spastic) side from the nonaffected
(nonspastic) side (both with p<.0001*). In addition, the intraclass correlation
coefficient, standard error of measurement, and minimum detectable differences
were highly consistent for both devices. CONCLUSION: Our findings suggest that
the Wii remote may serve as a convenient and cost-efficient tool for the
assessment of spasticity.
