PURPOSE The objective of this study was to evaluate the effect of Tai Chi Chuan (TCC) on health fitness in older individuals. METHODS Thirty-eight community-dwelling persons aged 58 to 70 yr completed this study. The TCC group included 9 men and 11 women; the control group included 9 men and 9 women. The TCC group practiced TCC for 11.2+/-1.4 months, with(More)
The phenotypic transformation of well-differentiated epithelial carcinoma into a mesenchymal-like state provides cancer cells with the ability to disseminate locally and to metastasise. Different degrees of epithelial-mesenchymal transition (EMT) have been found to occur in carcinomas from breast, colon and ovarian carcinoma (OC), among others. Numerous(More)
OBJECTIVE To use kinetic assessment of the sit-to-stand movement as a means of sorting out those stroke patients at risk for falling. DESIGN A retrospective study, using a force platform to assess sit-to-stand performance and to determine its correlation with falls in stroke patients. SETTING Hospital-based rehabilitation units. METHODS Thirty-three(More)
Eighty patients with spinal cord injury (SCI) and neurogenic bladder were studied. Among them, 28 (70%) cases in the control group and 32 (80%) cases in the electroacupuncture group achieved ultimately balanced voiding and were selected for further analysis. The acupuncture group received electroacupuncture at four acupoints: Chung Chi (Conception Vessel(More)

SETTING Community setting. PARTICIPANTS Forty-one community dwelling subjects aged 61.1 +/- 9.8 years undertook a TCC program. Nine dropped out during the study. Pretraining and(More)
Tai Chi Chuan (TCC) is a popular Chinese conditioning exercise, however, its exercise intensity remains controversial. The objective of this study was to determine the exercise intensity of Yang TCC by measuring heart rate (HR) responses and oxygen consumption (VO2) during practice.

This epidemiological study analyzed risk factors for low back pain (LBP) in nursing personnel in a 5000-bed medical center in the Republic of China. Of the 3212 eligible nursing personnel, 3159 (98.3 per cent) responded to the mail survey. Risk factors for LBP were age, stature, body weight, duration of work, work habits, and sitting posture.

BACKGROUND Decreased equilibrium in standing and walking is a common problem associated with hemiplegic stroke patients. Stroke patients with balance problems are prone to falls. In addition to spatial recognition, the appropriate pattern of muscle activity to preserve balance depends on sensory and motor processes. Previous reports have mentioned that the(More)
OBJECTIVE To investigate effects of brain lesion profiles that combined sizes and locations on motor recovery and functional outcome after stroke in hemiplegic patients. DESIGN Delimiting sizes (a threshold lesion size) of 5 primary locations were identified to establish brain lesion profiles based on magnetic resonance imaging findings 1 month after(More)
Recurrent pneumothorax is rare during pregnancy. We describe a Chinese woman, with a history of spontaneous pneumothorax managed with an intercostal drain, who developed a recurrent pneumothorax during her 32nd week of pregnancy. There is no consensus on management in this situation. We review the literature and discuss different management approaches.(More)
