The purpose of this study is to investigate the gait characteristics in Parkinson's disease patients. Specifically, the total stance time and the ratio of each stance phase (heel strike, mid-stance, propulsion) are analyzed from the foot-pressure measurement system which requires low cost and small space compared to the conventional gait analysis system. The gait characteristics were analyzed in 23 Parkinson's disease patients (before and after L-dopa medication), 34 elderly (sixties) normal subjects and 21 young (twenties) normal subjects. Bradykinesia global score (self-developed score of slowness of body movement) of patients before medication was determined to see the relationship between the score and the gait characteristics. The total stance time was greater in the erde. of patients, elderly, youngs (p<0.05). The phase ratio of heel strike and propulsion was smaller and that of mid-stance was greater in the order of patients, elderly, youngs (p<0.05). However, there was no significant difference in the above gait characteristics of patients before and after medication. There was a tendency, though statistically non-significant, that the total stance time is longer and the propulsion phase ratio is shorter in patients with greater Bradikinesia global scale, and this tendency was relieved after medication.

The purpose of this study is to investigate the effects of sex and age and their interactions in premotor-time (PMT) of ankle muscle. Forty-eight elderly subjects (aged 65-90 years) and thirty young subjects (aged 19-27 years) participated in this study. Subject were instructed to perform maximal, voluntary, isometric, bilateral contraction of ankle muscle in reaction to auditory stimulus to determine PMT. As analysis variables, PMT, intrasubject variability of PMT and asymmetry of PMT between dominant and nondominant legs were used. As statistical analysis, two-way ANOVA was performed to assess the main effects of age group and sex and also their interactions. All variables showed significant age effects (p<0.01). However, no sex effect and interaction existed in all variables in both dominant and nondomiant legs. Theses results suggest that the PMT of ankle muscle is related to the age-related deterioration in postural control, however, not related to the sex-difference of fall incidence in the elderly population.

The purpose of this study was to quantify the clinical assessment of rigidity at wrist in patients with Parkinson's disease. The experimental system was designed that the effect of gravity was negated by restricting motion at the horizontal plane and inertia was predetermined from a biomechanical measurement. Forty five patients with Parkinson's disease participated in this study. Viscoelastic properties were calculated from the experimental data acquired during intermittent passive movement of wrist. Viscoelastic constants correlated well with the rigidity scores of UPDRS, i.e., Spearman's r=0.733 and 0.905 for spring and damping constants, respectively. The results suggest that viscoelastic properties can be used as quantitative measures of rigidity.
