Statistical analyses were made regarding 104 various clinical data obtained from 512 hemiplegic patients who had been in the Izu-Nirayama Onsen Hospital for rehabilitation in the past five years.
In this paper, 32 of the factors especially related to ADL in the involved lower extremity were analyzed. The top seven factors which were most highly coefficient are as follows:
1. Degree of improvement of Brunnstrom stage in the involved lower extremity.
2. Muscle strength in the healthy lower extremity.
3. Degree of recovery of motor function in the involved lower extremity during hospitalization.
4. No urinary incontinence.
5. Correct application and usage of braces and artificial aids.
6. Maintenance of full passive ROM of the involved lower extremity.
7. Marked improvement in the total evaluation of the involved lower extremity (including ADL, PROM, Brunnstrom stages, etc.).

In this study, the performance of 117 aphasic patients was compared respectively with that of 24 right and 34 left nonaphasic hemiplegic patients on three nonverbal tests, the Kohs' Block Design Test, the Raven's Standard Progressive Matrices and WAIS Performance Subtests. Aphasia was assesed using the Nanasawa Diagnostic Aphasia Test and the severity was rated in four grades, ‹4› is the mildest and ‹1› the most severe.
The results of the analyses are summarized as follows:
1) The group involved all aphasic patients scored significantly lower on many nonverbal tests than the two groups of nonaphasic hemiplegic patients.
2) When the aphasics were rated in four grades, the mildest group, ‹4› was not inferior in all the nonverbal tests than the two nonaphasic groups. But the more severe aphasic groups, ‹3›-‹1› were significantly inferior in many tests than both the mildest and the nonaphasic groups.
3) In the rather mild aphasic group, ‹3›, there were some patients who obtained the lowest scores on the nonverbal tests, and conversely there were some who obtained the higest scores in the most severe aphasic group, ‹1›. This showed that the verbal and the nonverbal abilities were not always correlated.
These findings were discussed from the view points of the verbal mediation in the nonverbal tests and the locus or extent of the brain damage.

The air-cushion socket of below knee prosthesis was designed by Wilson in 1968. This socket is a modification of P. T. B. socket having three parts which are hard outer shell with no bottom, silicon rubber made inner elastic socket and a cap covering distal end of socket. In between the inner elastic socket and a cap, air-tight space is formed. This air-tight space acts like an air mat, supports a part of body weight at the stump end and aids suspension of prosthesis during swing phase. The fabrication of this socket, however, is too complicated.
The purpose of this study was to investigate the real function of air-cushion as well as to simplify fabricating method.
Methods:
1) The fabrication of socket was simplified making an inner socket with elastic silicon rubber made lower part and flexible resin made upper part, and rigid outer socket. Socket was designed for K. B. M. socket.
2) Pressure of air-cushion and strain of socket were recorded during walking with foot switches to show walking phase.
3) Two sockets were made. One was fabricated from the positive model from original K. B. M. socket, another was fabricated from the positive model according to Wilson's method. Former was called A-socket, latter was called B-socket. A piece of 2mm thickness of leather was attached to the patella tendon seat of B-socket later.
Results:
1) Dynamic change of pressure of A-socket was total 17.54mmHg±0.98, that of B-socket was 21.47mmHg±0.93, and that of B-socket with 2mm thickness leather attached to patella tendon seat was 20.37mmHg±0.96.
2) Pressure of air-cushion suddenly began to increase from heel contact and got into a peak at foot flat. From heel off, pressure began to decrease suddenly and got into a peak at just after toe off.
3) The strain of socket was maximum at later half of midstance.
Conclusion:
1) The air-cushion plays an important role for the weight bearing at the begining of stance phase.
2) Patella tendon seat supports weight mainly at the later half of stance phase.
3) Suspension at push off and early part of swing phase is important.

In order to study the relationship between bicycle-ergometer test and treadmill test, various parameters of cardiac function were compared before, during and after giving multiple loads in identical normal subjects and cardiac patients.
Method: Utilizing bicycle-ergometer, 5-minutes 50w/sec exercise was initially loaded in 49 cases consisted of 10 normal subjects and 39 patients with coronary heart disease (17 cases), valvular heart disease (16 cases) and hypertensive heart disease (6 cases) who were also divided into groups as Classes I (10 cases), II (22 cases), III (7 cases) of New York Heart Association (NYHA).
After full rest, 5-minutes 75w/sec exercise was then loaded in well-tolerated cases of 50w/sec exercise loading test, or 5-minutes 25w/sec exercise in non-tolerated cases.
3-7 days later, utilizing treadmill, 5-minutes 5°·30m/min exercise was loaded in these 49 cases. After full rest, 5-minutes 10°·50m/min exercise was loaded in well-tolerated cases of 5°·30m/min exercise loading test, or 5-minute 2.5°·20m/min exercise in non-tolerated cases.
In each test, the exercise loading was stopped when severe dyspnea, fatigue, palpitation, dizziness, slight chest pain, etc appeared, or S-T segment depression exceeding 2.0mm, or S-T segment elevation exceeding 2.0mm was observed on ECG.
Results: No significant difference in relative metabolic rate (RMR) and oxygen consumption were observed between 50w/sec and 5°·30m/min method, and between 25w/sec and 2.5°·20/min method. However, the RMR and the oxygen consumption in 75w/sec method were significantly lower than those in 10°·50m/min method.
Analysing the data of change in heart rate in exercise, maximum heart rate, 3-minutes total heart rate in recovery, physical fitness index (PFI), oxygen pulse, oxygen debt and ECG findings, it was found that the amounts of load of 50w/sec and 25w/sec were almost equal those of 5°·30m/min and 2.5°·20m/min, the amounts of load of 10°·5m/min was stronger than those of 75w/sec.
In 50w/sec method, severe complaints appeared in 20% of Class II (interrupted cases) and 83.3% of Class III patients. In 5°·30m/min method, severe complaints appeared in 20% of Class II (interrupted cases) and 28.6% of Class III patients.
Dullness of the lower-extremities and palpitation appeared much more frequently in bicycle-ergometer method than in treadmill method in the extent of 50-75w/sec or 50°·30m/min-10°·5m/min. Dyspnea appeared in both methods in similar frequency.
The exercise loading test using bicycle-ergometer was not suitable for some women, middle-or more than middle aged, because of their unskillfulness.
It was concluded that the treadmill method is more natural exercise loading test than bicycle-ergometer method for Japanese.
