OBJECTIVE: To compare the effects of Tai Chi (TC, n = 37) and Western exercise (WE, n = 39) with an attention-control group (C, n = 56) on physical and cognitive functioning in healthy adults age 69 +/- 5.8 yr, in a 2-phase randomized trial. METHODS: TC and WE involved combined class and home-based protocols. Physical functioning included balance, strength, flexibility, and cardiorespiratory endurance. Cognitive functioning included semantic fluency and digit-span tests. Data were analyzed using intention-to-treat analysis.

Tai Chi is a traditional Chinese conditioning exercise that has been used to integrate slow movements, controlled breathing, and mental concentration. The aim of the study was to determine whether Tai Chi training in addition to cardiac rehabilitation would result in a shift toward increased vagal activity of autonomic markers, such as baroreflex sensitivity (BRS) and heart rate variability (HRV). Twenty patients with coronary heart disease (CHD) (male/female: 13/7, mean age: 67.8 +/- 4.2 years, mean interval time after a coronary event: 19.8 months) completed this study.

OBJECTIVES: This study sought to determine whether participants in taijiquan classes would report increases in mindfulness greater than that of a comparison group, and whether changes in mindfulness were associated with improvements in mood, perceived stress, self-regulatory self-efficacy, and sleep quality. DESIGN: The study design was quasi-experimental with repeated measures. SETTINGS/LOCATION: The study was set in a midsized public university. SUBJECTS: Students aged 18-48 years old enrolled in 15-week courses of either taijiquan (n=76) or special recreation (control group, n=132).

Gait & Posture

This study compared the biomechanical characteristics of stepping in 10 older (aged 55+ years) Tai Chi (TC) practitioners and 10 age-matched non-TC (NTC) controls. Subjects were asked to take a step on an auditory cue as fast as possible, in the forward and backward directions, and with and without mental distractions, respectively. Stepping characteristics included step initiation time, preparation time for foot off, foot contact time, and step length and width. The results showed that both groups had similar step initiation time, step length and forward step width (p>0.466).

OBJECTIVES: T'ai chi is a form of mind-body practice used as exercise in China, though limited data are available on characteristics of t'ai chi users and factors associated with practice. METHODS: Characteristics of and factors associated with t'ai chi practice among middle-aged and elder Chinese in Shanghai China were analyzed utilizing baseline data from the Shanghai Women's Health Study and Shanghai Men's Health Study. Logistic regression modeling was used to identify independent factors associated with the practice of t'ai chi among men and women.

BACKGROUND: The prevalence of metabolic syndrome (MetS) is growing rapidly in China. Tai chi and dancing are common types of exercise among middle-aged and elderly Chinese. It remains unclear whether these activities are associated with a lower risk of MetS. METHODOLOGY/PRINCIPAL FINDINGS: A total of 15,514 individuals (6,952 men, 8,562 women) aged 50 to 70 years from the Dongfeng-Tongji Cohort in Shiyan, China participated in a cross-sectional study. Physical activity and other lifestyle factors were assessed with semi-structured questionnaires during face-to-face interviews.

OBJECTIVES: Although pediatric patients with chronic pain often turn to complementary therapies, little is known about patients who seek academic integrative pediatric care. DESIGN: The study design comprised abstraction of intake forms and physician records from new patients whose primary concern was pain. SETTING/LOCATION: The study setting was an academic pediatric clinic between January 2010 and December 2011. SUBJECTS: Of the 110 new patients, 49 (45%) had a primary concern about headache (20), abdominal pain (18), or musculoskeletal pain (11).

Surgical Laparoscopy, Endoscopy & Percutaneous Techniques

Surgery is still the main modality in the treatment of hepatic hydatid disease. Laparoscopic methods, with their low morbidity, have gained prominence in many fields and, in some cases, have nearly replaced open surgery. In this report, a laparoscopic method for the treatment of hepatic hydatid disease is described, and the results in the 46 cases are presented and the published articles were reviewed. The method involves laparoscopic cystectomy, pericystectomy, and liver resection for hydatid disease.

BACKGROUND: Tai Chi (TC) has proven to be effective at improving musculoskeletal fitness by increasing upper and lower body strength, low back flexibility and overall physical health. The objectives of this study were to examine changes in musculoskeletal health-related fitness and self-reported physical health after a 16 week TC program in a low income multiple ethnicity mid to older adult population. METHODS: Two hundred and nine ethnically diverse mid to older community dwelling Canadian adults residing in low income neighbourhoods were enrolled in a 16 week Yang style TC program.
