Two series of experiments about eccentric contraction exercise were conducted. One was to see the effects of this exercise in comparison to the modification of McGovern and Luscomb of progressive resistance exercise. Abductor digiti minimi muscle was chosen as an object. Another experiment was to see the cross education effect of this exercise as well as to see the attitude of different muscle reacting to this exercise in comparison to former experiment.
Two ergometers......finger ergometer and knee ergometer......were designed and graphs were analized. The following conclusion were induced.
1. There was no significant difference in increase of force between progressive resistance exercise and eccentric contraction exercise.
2. There was a significant difference in increase of work between progressive resistance exercise and eccentric contraction exercise. Increase of work was more in eccentric contraction group. Increase of work was considered to have increase of reserve of muscle force.
3. There was good cross education effect. Although some physiological contradictions might consider, there was an important clinical meaning.
4. A joint angle at which maximal force delivered was constant zero degree in abductor digiti minimi muscle. In quadriceps muscle, first two tests showed around 110 to 120 degrees then later around 150 degrees.
5. Formation of plateau in graph was observed in final test.
6. It was my impression that the eccentric contraction exercise was one of the good methods to increase muscle strength. The characteristic fact in this exercise was the increase of work and power. Also the good cross education effect will be used clinically.

Classification of hemiplegia has not been accomplished though this disease is very frequent. The clinical picture of hemiplegia presents as uniform appearance from one standpoint but from the other stand point it has many variety of manifestation, in the degree of motor impairment, potentiality of improvement, degree of spasticity and their distribution pattern.
This classification is provided by two fundamental principles, 1) Classify by the localization of lesion when it can be clarified. 2) If it is not clear, classify by the intensity, distribution pattern, and chronological sequence of spasticity.
Thus following eight types are determined.
(A) Type showing spastic posture from early stage
A-1 Rigidity type
A-2 Immediate Wernicke-Mann type
(B) Type showing flaccid posture in early stage
B-1 Delayed Wernicke-Mann type
B-2 Hypotonic type
B-3 Prolonged atonic type
(C) Syndromes that the lesion is clear.
C-1 Ponto-bulbo-cerebellar syndrome
C-2 Thalamo-basal-ganglia syndrome
C-3 Circumscribed cortical syndrome
(D) Unclassified group
Those groups have characteristics respectively, and they are useful for the estimation of prognosis, precaution against complication, and choice of therapeutic procedure.
