Statistical analyses were performed on 512 stroke patients, who had been admitted to Izu-Nirayama Rehabilitation Hospital within the past five years, with special attention paid to functions of activities of daily living (ADL). There were 104 items studied in relation to ADL functions, including case history, clinical symptoms, neurological findings (including motor and speech functions), complications such as diabetes, hypertension, and the patients' successful return to community life.
Among those factors studied, one which was highly related to successful return to community life was ADL of the involved upper extremity. Thirty-three item categories were found to be most important in influencing recovery of the involved upper extremity. The coefficient of determination of these factors was 87.58%. The highest six of these categories were most important in predicting the recovery of the ADL functions of the involved upper extremities.
The highest six factors are as follows:
1. Good state of function of ADL in the involved upper extremity upon admission.
2. Improvement in Brunnstrom stage of the upper extremity upon discharge.
3. Absence of urinal incontinence.
4. Passive range of motion (PROM) of upper extremity nearly full range upon admission.
5. Rapid advancement to plateau stage under medical and rehabilatative treatment.
6. Low age group at onset of stroke.
It was proved that the above-mentioned factors greatly contributed to the patient's successful return to the community, as far as ADL of the involved upper extremity were concerned.

The purpose of the study was to clarify the factor for the delayed speed in geriatric gait.
The subjects were 21 elders (average age: 67) and 17 young males (average age: 22) tested for comparison.
The method included filming with 16mm movie camera of the subjects who wore marker (target) at each joint and walked on specially prepared board platform. An analysis was made from the taken film using motion analizer. The average speed for the elder group was 2.44km/h and that of the younger group was 4.16km/h.
The major factors delaing the speed in the elder group were:
(1) difference in cadence (elder group: 84/min. and younger group: 110/min.) and
(2) difference in step length (elder groupe: 48cm. and younger groupe: 63cm)
(1) There were two causes making cadence small in the geriatric group.
(a) double support duration for elder group and younger group were 0.20 seconds and 0.14 seconds, respectively and longer time was required for push-off of the elder group.
(b) swing phase of 0.52 seconds in the elder group was longer than that of the younger group with actual timing of 0.40 seconds. It was thought power for push-off had an influence on this difference.
(2) There were two causes making the step length short in the geriatric group.
(c) step length in the elder group was 7cm shorter than that of the younger group, probably due to the fact that lower extrimity (56cm) in the elder group was shorter than that of younger group (77cm).
(d) step length in the elder group was 8cm shorter than in the younger group, this was probably due to the difference in the joint angles at the time of heel contact.

In an attempt to carry out a more dynamic analysis of gait than that accomplished by conventional means, we analyzed so-called normal gait by photographing it with a mobile 16mm movie camera from both the sagittal and coronal planes, and then analyzing the motions of various location with a motion-analyser and processing the data obtained with an electronic computer.
The result of this was that no difference could be seen in the analysis of gait one plane and that two planes. However, similar determination of experimentally induced abnormal gait, and processing of data obtained, revealed significant differences between the two planes in cases of abnormal gaits with large angles of movement of joints. Also, trends similar to those described in many earlier reports were noted in regard to hip joint angles of extension and flexion and angles of adduction and abduction, knee joint angles of extention and flexion, and foot joint angles of planter and doral flexion, while findings more or less diff erent to those of earlier reports were noted in regard to hip joint inner and outer rotation and horizontal adduction and abduction, and pelvic rotation, femoral rotation and foot rotation.
It can be claimed, on the basis of these findings, that photography from three planes is necessary for accurate determination of the rotation of pelvic, , hip and foot joints, although photography from the sagittal and coronal planes is sufficient for determination of the angles of extension and flexion of hip, knee and foot joints.
