1. Introduction
The consciousness of health of the spinal cord injuries is influenced by doing sports regularly, concerned in their needs hierarchial grades and the bases of their daily lives, and in addition to these, affected by their medical conditions of having or not bedsores and urinary tract infections.
The purpose of this study is to analize the changes of the ventilation function of the spinal cord injuries who are intimating with sports.
2. Methods
The subjects are seven male paraplegics due to spinal cord injury who have not bedsores nor urinary tract infections, and play wheelchair basketball more than two times per month.
In order to detect changes of their ventilation function, measurements were done in October 1980, 1981 and 1982, using autospirometer.
3. Results
(1) Forced vital capacity (FVC) and % vital capacity (%VC = FVC/predicted vital capacity) of the majority of the examined subjcets were normal.
(2) Forced expiratory volume in 1 second (FEV₁), forced expiratory volume% in 1 second (FEV₁% = FEV₁/FVC) and % expiratory volume in 1 second (%EV₁ = FEV₁/predicted vital capacity) showed a tendency to improve year by year, and the condition of respiratory function of all the subjects was evaluated normal from the view point of %EV₁.
(3) Within the ventilatory impairments, the obstructive ventilatory impairment decreased every year, and the ventilation function of all the subjects showed a tendency towards normal.
(4) Health consciousness of the subjects was clearly related to health condition, measured by the pulmonary function test.
4. Conclusion
It seems that the condition of the spinal cord injuries from the view point of ventilatory function was influenced by continual practice and frequency of doing sports.
Therefore, the cardio-respiratoryfunction of the spinal cord injuries has a great influence on their health and health consciousness, as well as their needs hierarchial grades and the bases of their daily lives.

Poliomyelitis anterior acuta epidmica is an infectious disease commonly abbreviated to Polio. In Japan, the incidence has been greatly reduced, and is now negligible thanks to the improvement of vaccines.
In the past, however, the disease was prevalent in cycles of about ten years, and in 1951 the incidence was the highest ever recorded in Japan. At that time the therapy for the limbs affected by poliomyelitis included arthrodeiss, tendon shifting and orthosis. Secondary impairments due to the weakened muscular force, articular impairments or the difference of the length of the legs also appeared in a considerable number of cases.
Recently, the authors had the opportunity to participate in an examination of adult diseases for citizens living in the Suginami-ward, in Tokyo, and discovered a female patient with left lower limb paralysis due to poliomyelitis, with muscle testing giving a poor result, genu recurvatum 35° and a 4.5 cm difference in the length of the legs. It was observed that she could walk with a T-cane gait, but secondary impairments occurred due to compensatory actions by the typically abnormal gait causing pain over the anterior region of the right ribs.
For the genu recurvatum of this patient, a polypropylene type double-Klenzak system knee orthosis was attached, and axillary correction was performed by extending the posterior of the femoral cuss upwards. For the lateral motions, the femoral cuff was extended forwards from the support up to the shin bone, together with the correction of the different lengths of legs by wearing boots, and with the prevention of lateral motions by placing wedges in the inside of the shoes and in the outside of the shoe soles.
As a result, the genu recurvatum, lateral motions, and dangle foot were prevented and different leg lengths were corrected, so that a stabilized gait and better appearance on walking were brought about. In addition, the patient was able to ride a bicycle and to drive a car.
