Stepping analysis in patients with spinocerebellar degeneration and Parkinson's disease.
POLGON (Polarized light goniometer) was used to evaluate ataxia during stepping movements in patients with spinocerebellar degeneration (SCD) and Parkinson's disease. The measurements included mean angular change of shoulders (M.A.C.S.) and its coefficient of variation (C.V.). In patients with SCD, the values of M.A.C.S. were significantly larger at 1.0 step/s than those at other stepping rhythms. This results suggests that the stepping rhythm of 1.0 step/s is useful for the detection of cerebellar ataxia. The values of C.V. correlated with the degree of advancement of SCD. In patients with Parkinson's disease, the values of M.A.C.S. tended to decrease because of the restricted elevation of the knee, while those of C.V. were increased. The results showed that the stepping test using the POLGON was useful for estimation of the characteristic disequilibrium of SCD and Parkinson's disease.
