Early habilitation was performed on 43 children with mental retardation and its effects were reviewed. As the methods, weekly physiotherapy and operant therapy added with semi-monthly sports therapy were employed. Moreover, the children were directed towards the establishment of life rhythm encouraging mixed education with normal children at nursery schools.
The development was evaluated by our own behavior scale and Denver's development scale.
Effects of early habilitation with statistical significance were observed in both group A of habilitation commenced within 6 months after birth and group B of habilitation commenced beyond 6 months after birth. As to the 18 cases of group B with more than 2 years of habilitation, the mean total development rate showed no significant difference before and after the habilitation, but the development rate in self-control and sociability was improved at a significant level of 1%.
The abnormal behaviors in children with mental retardation could not be prevented like spasm, unvoluntary motion and ataxia in children with cerebral palsy cannot. However, proper assistance to handicapped children by early habilitation made it easier far them to pass through the appointments with behavioral development enabling them to elevate their capability of social life.
Discussion was made on the significance and effectiveness of early habilitation for children with mental retardation.

Visuo-motor system was studied by Eye Camera on patients with central nervous system disorders; patients with hemiplegia, ataxia and parkinsonism, and normal controls. The subjects with Eye Camera were asked to walk in 10 meter, with trying to fix his eyes on one point of the wall in front of him. Number of his steps and time required were measured, and the movemnts of the point of his gaze were analysed by using video tape. The area surrounded by the movement of the point of the gaze, the distance of vertical movement and horizontal movement were measured, and the ratio of horizontal movement to vertical movement was calculated.
The results were as follows; 1) number of steps and time required: patients took nealy twice steps and time as many as normal control, and the numbers were largest in patients with hemiplegia. 2) the form of the movement of gaze: each group of the patients showed each specific form of the movement of gaze, and especially in cases with ataxia, it was very large irregular form. 3) the area surrounded by the movement of position of the gaze: the largest in patients with ataxia and the smallest in patients with parkinsonism. 4) the vertical movement: the biggest in normal control, slight smaller in ataxia, much smaller in hemiplegia and the smallest in parkinsonism. 5) the horizontal movement: the smallest in control, bigger in cases with ataxia and hemiplegia than in cases with parkinsonism. 6) the ratio of horizontal movement to vertical movement: smaller than 0.5 in normal control, and bigger than 0.5 in all patients with central nervous disorders. 7) the deviation of the point of gaze from the midline: tendency of deviation to left side in all cases examined. In hemiplegia, horizontal movement was bigger in cases with left hemiplegia than in cases with right hemiplegia. 8) the change with age: in control and parkinsonism, the vertical movement and the area showed the decrease with age, but in ataxia, the horizontal movement and the area tended to increase with age.

The current trend for the treatment of patients with myocardial infarction is to leave the bed or hospital at an early stage in the U. S. A. and Europe. In our department, we usually perform a 4-week rehabilitation program. However problems may occur when the patient takes a warm bath during the program. Therefore, we studied the proper time and safeties of warm bathing during rehabilitation. During warm bathing, the heart rate of myocardial infarction patients increased, but their blood pressure was significantly reduced. PEP/ET also significantly decreased. The decrease in ΔPEP/ET was significantly lower in the subgroups with Peel's prognostic index of 10 or more, a CTR of 50% or more, or extrasystoles (+). In the subgroup showing abnormal electrocardiographic changes during warm bathing, the age was significantly higher, the infarction size larger, the duration in hospital longer, the physical work capacity lower, the severity significantly higher according to the Killip's classification and the Peel's prognostic index at admission, in addition the coronary angiogram showed multiple vessel lesions, and the CTR was also high. Patients taking a second warm bath at the completion of rehabilitation showed significant improvements in ΔPEP/ET. For patients capable of warlking for 200m at a time and having a physical work capacity of 50 watt or more, warm bathing at a temperature of 40°C is considered to be safe.
