The purpose of this study was to analyze tilting reaction of frontal and sagittal directions on healthy men using electric balance board. The subjects for the study were 33 normal adults (male 25, female 8). They were 19 to 33 years old with an average age of 23.0 years, an average height of 169.3 cm and an average weight of 60.8 kg.
The results obtained are as follows;
1. Tilting reaction at frontal and sagittal directions showed a decrease of inclination of head and trunk parts for increasing velocity of inclination. There were significant at a five percent level of confidence.
2. Tilting reaction with blindford showed a decrease of inclination of head and truk parts for inclination, then no significant confidence.
3. Velocity of inclination on one degree per second, showed a rising tendency at frontal and sagittal direction comparing blindfold.
4. Velocity of inclination on three degrees per second, showed significant at one and five percent levels of confidece at comparing blindfold, then sagittal direction did one and five percent levels of confidence only left inclination.

Guillain-Barré's syndrome has been considered to show a relatively good recovery of the physical functions. In the present study, we report the analysis of the courses of recovery of the physical functions from onset of the illness to the final observation in 13 cases with this disease admitted to the Fourth Department of Internal Medicine in this hospital since 1979 to 1984. They were 7 meles and 6 females ranging from 9 to 65 years of age with an average age of 31.1 years. The type of motor paralysis was quadriplegic in 9 and paraplegic in 4 cases, all these motor dysfunctions being preceded by the signs and symptoms of the upper respiratory tract infections such as fever, malaise and arthralgia. Among 9 quadriplegic patients two cases finally had respiratory as to receive tracheotomy, and other three had facial palsy as well. The duration from the onset to the peak of the symptoms ranged from 3 to 7 days in five, and from 8 to 14 days in six and 15 to 28 days in two cases respectively. All four paraplegic cases also had transient sensory disturbances, weaknesses and arthralgia in the upper limbs in the early period of the disease, but these symptoms subsided within 3-7 days after the admission followed by paraplegia as the final feature.
Motor dysfunctions in these cases were evaluated by MMT, ROMT and by ADLT as well. The functional training was started from the bedside stages including the respiratory exercise, and the braces of the lower limbs were prescribed for 5 and the crutches were for 4 cases during the courses. The average duration of the hospitalization of all 13 cases was 4.0 months, and the average duration until returning to the previous occupations after discharge was 7.1 months. There were four cases who showed delayed recovery of the functions of the lower limbs even 6 months after the onset of the disease. These patients have been still under observation.
According to the above mentioned results, the severity of the symptoms at the onset of the illness and the duration of recovery were not well correlated; the severer cases with rapid exacerbation of paralysis showed fairly good recovery which was completed within the equal durations to those of the more mildly paralysed cases. There were some difference in duration of recovery between the elderly and younger patients, the duration being some what shorter in the latter than in the former.
