    Walking and standing require muscular force to support the weight of body provided by the whole of lower extremities. Isometric gross muscle strength (strength of a one leg press) exerted in the direction of the extended leg in the supine position was measured at knee angles of 15, 30, 45, 60 and 75 degrees. This parameter was determined for 20 subjects, 10 males and 10 females. The relation between the one leg press and maintaining the standing position on one leg was examined using surface EMG in 6 males. As a result, the strength of one leg press exerted with maximum effort was greatest at a knee angle of 15 degrees in the direction of extension. This parameter was recognized to have characteristic rational muscular force exertion since to keep one leg standing requires muscular force near the knee extension position and the mid-stance phase of the gait is at a knee angle of 15 degrees. Furthermore, surface EMG of lower extremity muscles during one leg press while supporting the body weight indicated muscular activity essentially the same as that for maintaining one leg standing. Thus, the strength of one leg press was suggested to possibly express the muscular force required for keeping one leg standing.

    Ten healthy adult female subjects were asked to perform randomly one of five different ambulatory tasks, and their Physiological Cost Indexes (PCI) were measured 3 min after the tasks in order to investigate the relationship between ambulatory speed to PCI. The results revealed that it was not Mode C (comfortable walking speed), but Mode S (slow walking speed), which yielded the lowest, PCI 0.223 ± 0.09 bts/m at an average ambulatory speed of 59.3 ± 9.0 m/min. It was possible to approximate the relationship between PCI and ambulatory speed for both individual subjects and for the group as a whole with a quadratic polynomial expression. The relationship of actual PCI values to predicted PCI values showed a clear linear regression. The results obtained demonstrated the possibility of accurate prediction of PCI scores for randomly assigned ambulatory speeds.

    The purpose of this study was to examine the relationship between the severity of Parkinsonism and the effects of heels lift on the postural sway in standing and walking abilities. A total of 29 patients with Parkinsonism (mean age 66.5 years) were participated in the study and classified by the severity scale of Yahr into 3 groups, mild (n = 12), moderate (n = 11), and severe (n = 6). Also 10 normal controls were enrolled. The postural sway was measured with the center of pressure moniter in 2 heels conditions (normal and with the heels lifted) and 3 standing conditions (static, lateral shift, anterior-posterior shift). There were no significant effects of the lifting heels on any items for normal controls. Analysis of variance revealed that moderate group showed significant improvement in all measured variables, whereas mild and severe groups showed significant improvement in dynamic balance and static balance, respectively.

    This study investigated factors that limit to participate and complete phase Ⅱ cardiac program. One-hundred and five patients (77 men and 28 women) with acute myocardial infarction who had completed cardiac inpatient program were enrolled in this study. Sventy-one (68%) out of the 105 patients participated in phase Ⅱ cardiac program. The patients aged under 64 years had higher rate to participation of phase Ⅱ program than aged over 65 years. Lack of motivation, one of the reasons for non-participation, was frequent in patients aged 65 years or over. Sixty (85%) out of the 71 patients accomplished the phase Ⅱ cardiac exercise program. Thirty-one problems requiring to quit exercise, or a change of medications occurred during exercise in 28 patients. Twenty of these problems originated in the cardiovascular events (arrhymias, increased heart rate, ST depression, fall in blood pressure during exercise, chest pain, heart failure, and reinfarction), and seven were orthopedic problems (arthralgia and myalgia). Both the proportions of incidence of cardiovascular problems and orthopedic problems were higher in female patients. These results suggest that phase Ⅱ cardiac program should proceed taking into consideration patients' age and sexual differences as well as evaluation in cardiac function.

    The purpose of this study was to determine the effectiveness of Neurodevelopmental Treatment (NDT) for children with motor disabilities. Meta-analysis was used to estimate the effectiveness through reviewing previous studies. Meta-analysis is a relatively new statistical method that allows us to find out overall effectiveness of a therapeutic intervention through reviewing previous research articles that relates to the issue. The effectiveness of the therapeutic intervention is represented by the effect size that is defined as the difference between the means of the experimental and the control group divided by the control group standard deviation. I estimated the effect size of the long term treatment through experimental studies which had published between 1985 and 1994 (Study 1). Furthermore, the short term effectiveness of NDT was estimated through studies that had published between 1970 and 1994, dealt with immediate effectiveness of NDT after one treatment session (Study 2). The effect size of the Study I was -0, 21, and of the Study 2 was 0.69. The results suggested that NDT intervention was not predominant against other control conditions while the changes of performances during short term NDT intervention was obvious.

    We had a case (male, 44 years) of suggested myopathy with winged scapula with abnormal muscle tone and reffered pain of the extremities and neck. It was considered that joint dysfunction was the main cause of the symptoms which included disturbance of joint-play motion, muscle spasm, reffered pain resulting from many clinical tests, examinations and the process of treatment. Physical therapy consisting mainly of arthrokinematic approach (AKA) and relaxation was performed. There was no winged scapula after one week of the therapy and no reffered pain of the extremities or neck after three weeks.
