ABSTRACT
Few reports have described the involvement of syringomyelia associated with diastematomyelia in the etiology of neurological deficits. We reported a case with syringomyelia associated with diastematomyelia. A female patient with diastematomyelia was followed up clinically over 14 years. At the age of 8, she developed clubfoot deformity with neurological deterioration. Motor function of the right peroneus demonstrated grade 2 in manual muscle tests. Continuous intracanial bony septum and double cords with independent double dura were observed at upper thoracic spine. Magnetic resonance imaging revealed a tethering of the spinal cord and syringomyelia distal to the level of diastematomyelia. Extirpation of the osseum septum and duralplasty were performed surgically. She grew without neurological deterioration during 7 years postoperatively. A long-term followed up case with syringomyelia that was possibly secondary to the tethering of the spinal cord associated with diastematomyelia, and effective treatment with extirpation of the osseum septum and duralplasty was described.

The purpose of this study was to analyse electromyographic characteristics of Tai Chi. The subjects, six healthy men, performed ; (1) the maximum voluntary contraction (MVC) of each tested muscle ; (2) three forms in 24-style Tai Chi ; (3) on a bicycle ergometer (100 w) and jogging (120 m/s). For each muscle, the maximum integrated EMG for one second was computed and standardized by MVC(%MVC). The results were as follows : (1) High muscle activity was observed during Tai Chi. In five muscles, the %MVC exceeded 60%. (2) In the rectus femoris m., the %MVC of Tai Chi was 6.8 times that of the bicycle ergometer and 10.3 times that of jogging (p<0.01). In a similar way, in the tibialis anterior m., the %MVC was 7.1 and 4.8 times (p<0.01), and in the rectus abdominis m., the %MVC was 6.3 and 4.9 times (p<0.01). We conclude that Tai Chi might be useful as an exercise in muscle strength training.
ABSTRACT
This study aimed to investigate the effects of Ball Exercise on physical functions related to fall prevention among community-dwelling elderly. Nineteen healthy elderly women voluntarily participated in a Ball Exercise course that consiste of 60-min classes once a week for three months. We assessed their physical functions at baseline and then again after the Ball Exercise course. Significant improvements (p<0.05) were observed in one leg standing without vision (+7.2 s), functional reach (+14.4%), trunk flexibility test (+7.1%), maximum walking speed (+17%), and the isometric muscle strength of the knee and ankle joints (+9.8〜35.7%), but no changes were observed in grasping power. This study suggested that Ball Exercise might be a suitable fall prevention and health promoting exercise for elderly people. We therefore concluded that ensuring a high level of physical functions is important to prevent falls and maintain a high quality of life for elderly people.
