Different modulation effects of Tai Chi Chuan and Baduanjin on resting-state functional connectivity of the default mode network in older adults
Abstract
The default mode network (DMN) plays an important role in age-related cognitive decline. This study aims to explore the modulation effect of two mind–body interventions (Tai Chi Chuan and Baduanjin) on DMN in elderly individuals. Participants between 50 and 70 years old were recruited and randomized into a Tai Chi Chuan, Baduanjin or control group. The Wechsler Memory Scale-Chinese Revision and resting-state fMRI scans were administered at baseline and following 12 weeks of exercise. Seed-based resting-state functional connectivity (rsFC) was calculated. We found that (i) compared to the Baduanjin group, Tai Chi Chuan was significantly associated with increased rsFC between the medial prefrontal cortex (mPFC) and right putamen/caudate and (ii) compared to the control group, Tai Chi Chuan increased posterior cingulate cortex rsFC with the right putamen/caudate, while Baduanjin decreased rsFC between the mPFC and orbital prefrontal gyrus/putamen. Baseline mPFC rsFC with orbital prefrontal gyrus was negatively correlated with visual reproduction subscore. These results suggest that both Tai Chi Chuan and Baduanjin can modulate the DMN, but through different pathways. Elucidating the mechanisms underlying different mind–body interventions may shed light on the development of new methods to prevent age-related diseases as well as other disorders associated with disrupted DMN.

Effects of individualized Tai-Chi on balance and lower-limb strength in older adults
Background
To investigate whether a simplified and personalized Tai-Chi program could be beneficial for practitioners. A prospective quasi-experimental observer-blinded controlled trial was done in Beitou District of Taipei City.
Methods
Community-dwelling adults aged 65 and older without debilitating disease (
N
= 50) participated the study. Those who were willing to participate in exercise program were assigned to individualized Tai-Chi (iTC) group (
n
= 20), receiving iTC training for 8 weeks, and traditional Tai-Chi (tTC) group (
n
= 15), receiving tTC training for 8 weeks. Those who were not willing to participate in exercise training were included in the control group (
n
= 15). Functional balance tests, the Berg Balance Scale (BBS), timed up-and-go (TUG) test, functional-reach test, and measurement of lower-extremity muscle strength were conducted before and 8 weeks after the intervention.
Results
Significant improvements were noted in all functional balance tests and strength assessments of 16 major lower-limb muscle groups in participants of the iTC group compared to the control group, whereas only BBS and muscle strength of hips and ankles were improved in the tTC group. Practitioners of iTC outperformed tTC in BBS and strength of two major muscles.
Conclusions
Personalized Tai-Chi training designed based on an objective measurement and conducted according to graded intensity and complexity benefitted practitioners after a short period.

The Effect of Tai Chi Chuan Training on Stereotypic Behavior of Children with Autism Spectrum Disorder
This quasi-experimental study investigated effects of Tai Chi Chuan training on stereotypic behavior of children with autism spectrum disorder. Twenty-three participants (mean age = 9.60 ± 1.40 years) were assigned to experimental (N = 12) and control (N = 11) groups. The experimental group received 12 weeks of Tai Chi training and all participants had pre, post, and one-month follow-up assessments. Stereotypic behavior measured using Gilliam Autism Rating Scale 2 Scores, was significantly altered by ~ 25% in the Tai Chi Chuan group. Behavioral change was maintained at follow up since there was no significant difference between that and the posttest. In conclusion, Tai Chi Chuan training is a useful and appropriate intervention to modulate behavior in individuals with autism spectrum disorder.

Complementary Use of Tai Chi Chih Augments Escitalopram Treatment of Geriatric Depression: A Randomized Controlled Trial
Nearly two-thirds of elderly patients treated for depression fail to achieve symptomatic remission and functional recovery with first-line pharmacotherapy. In this study, we ask whether a mind–body exercise, Tai Chi Chih (TCC), added to escitalopram will augment the treatment of geriatric depression designed to achieve symptomatic remission and improvements in health functioning and cognitive performance.
One hundred twelve older adults with major depression age 60 years and older were recruited and treated with escitalopram for approximately 4 weeks. Seventy-three partial responders to escitalopram continued to receive escitalopram daily and were randomly assigned to 10 weeks of adjunct use of either 1) TCC for 2 hours per week or 2) health education (HE) for 2 hours per week. All participants underwent evaluations of depression, anxiety, resilience, health-related quality of life, cognition, and inflammation at baseline and during 14-week follow-up.
Subjects in the escitalopram and TCC condition were more likely to show greater reduction of depressive symptoms and to achieve a depression remission as compared with those receiving escitalopram and HE. Subjects in the escitalopram and TCC condition also showed significantly greater improvements in 36-Item Short Form Health Survey physical functioning and cognitive tests and a decline in the inflammatory marker, C-reactive protein, compared with the control group.
Complementary use of a mind–body exercise, such as TCC, may provide additional improvements of clinical outcomes in the pharmacologic treatment of geriatric depression.

Effects of Tai Chi Chuan on physical function and health in breast cancer patients
Purpose
This study aims to explore the effects of Tai Chi Chuan (TCC) on physical function, hematological metabolic biomarkers, sleep quality, and mental health in breast cancer patients.
Methods
This was a prospective clinical trial that involved 37 breast cancer patients who had completed surgery treatment. Participants’ motor function, hematological examination, and self-rated questionnaire were assessed at the baseline and after the intervention.
Results
Through the 12-week TCC intervention, participants’ weights (
p
= 0.981), body mass index (BMI) (
p
= 0.913), and blood pressure (
p
= 0.374 for systolic BP,
p
= 0.299 for diastolic BP) remained stable; waist-hip ratio significantly decreased (
p
< 0.001); and post-intervention pulse rate (
p
= 0.011) and vital capacity (
p
= 0.062) slightly increased. In the aspect of motor function, the value of sit and reach (
p
< 0.001), grip strength of both hands (
p
< 0.001), and most active range of motion of neck and shoulder joint (
p
< 0.001 for anteflexion and both left and right lateroflexion of neck joint, both left and right adduction and rear protraction of shoulder joint) increased after intervention. Arm girth (
p
< 0.05 for arm girth in left styloid process of ulna, 5 cm below left cubital crease, left and right cubital crease, 10 cm above left and right cubital crease, and left axilla) showed a shrinking trend after intervention. According to the questionnaire of Pittsburgh Sleep Quality Index (PSQI) and the Hospital Anxiety and Depression Scale (HADS), participants’ sleep quality improved, and anxiety and depression remained stable after the trial (
p
= 0.021 for PSQI,
p
= 0.631 for anxiety,
p
= 0.182 for depression). Hematological examination of total protein (
p
= 0.016), albumin (
p
< 0.001), albumin-globulin ratio (A/G) (
p
< 0.001), high-density lipoprotein cholesterol (HDL-CH) (
p
= 0.002), and apolipoprotein A1 (APOA1) (
p
< 0.001) increased after intervention.
Conclusion
Motor function and sleep quality improved significantly after TCC intervention for 3 months in breast cancer patients. At the same time, some hematological metabolic biomarkers also changed better.
