[Purpose] The aim of the present study was to seek evidence for the effectiveness of Tai
Chi for patients with knee osteoarthritis (KOA). [Subjects and Methods] Systematic
searches were conducted of the China Journals Full-text Database, Pubmed, Medline, Science
Direct-Online Journals and CINAHL for studies published between 2000 and 2012. Studies
were evaluated based on following inclusion criteria: 1) design: randomized control,
clinical trial; 2) subjects: patients with a knee osteoarthritis diagnosis; 3)
intervention: exercise involving Tai Chi; 4) studies published in English or Chinese.
[Results] Six randomized control studies involving Tai Chi and knee osteoarthritis were
found. [Conclusion] Tai Chi was an effective way of relieving pain and improving physical
function. Further randomized controlled trials with large sample sizes and long training
period are needed to compare groups who perform Tai Chi training with other groups who
undergo other forms of physical exercise in order to confirm the efficacy of Tai Chi.
Background: Knee osteoarthritis is a common disease affecting a large number of old individuals worldwide. This study aimed to explore the effects of Baduanjin Qigong in patients with knee osteoarthritis. Methods: Fifty participants with knee osteoarthritis were randomly assigned to either an experimental group (n = 25) or a control group (n = 25). Participants in the experimental group received Baduanjin Qigong training for 12 weeks, with three sessions per week lasting 40 min per session. Participants in the control group did not receive any additional physical training. All of participants completed outcome (proprioception, postural stability, and functional ability) assessments at three time points (baseline, Week 8, 12). Results: Proprioception and Western Ontario and McMaster Universities Osteoarthritis Index function were statistically improved at eighth and 12th week of the intervention in the Baduanjin Qigong group (p < 0.05), while the control group did not have any significant changes. For postural stability at the anterior-posterior direction with eyes closed, Baduanjin Qigong group showed significant improvement compared to controls after the 12 weeks of intervention (p < 0.05). Conclusions: Regular Baduanjin Qigong practice helped the improvement of knee joint proprioception and postural stability, and reduction of pain, stiffness, and functional impairments of old adults with knee osteoarthritis. Well-designed randomized controlled trials with long-term assessment are needed. The trial was registered in Chinese Clinical Trial Registry (ChiCTR-IOR-16010042).

The aim of this study is to estimate the long-term cost-effectiveness of two different rehabilitation trajectories after severe traumatic brain injury (sTBI). A decision tree model compared hospitalization costs, health effects, and incremental cost-effectiveness ratios (ICER) of a continuous chain versus a broken chain of rehabilitation. The expected costs were estimated by the reimbursement system using diagnosis-related group and based on point estimates of the Disability Rating Scale (DRS); the health effects were measured by means of area under the curve (AUC). The incremental health benefit was estimated as the difference in the AUCs between the chains. Lower values on the DRS scale indicate better health; thus, smaller AUCs were preferred. The modeled population was a cohort of 59 patients with sTBI (30 in continuous chain; 29 in broken chain) with 6-weeks, 1-year, and 5-year post-injury follow-ups. Regarding the DRS estimates, 5-year AUCs were 19.40 (continuous chain) and 23.46 (broken chain). Across 5 years, the continuous chain of rehabilitation had lower costs and better health effects. By replacing the broken chain with the continuous chain, NOK 37.000 could be saved and 4.06 DRS points gained. By means of probabilistic sensitivity analysis, the majority of ICER estimates (67% of the Monte Carlo simulations) indicated that a continuous chain of rehabilitation was less costly and more effective. These findings indicate that the trajectory of continuous rehabilitation represents a dominant strategy in that it reduces costs and improves outcomes after sTBI under reasonable assumptions.
Depression, an emotion regulation disorder, is a prevalent mental illness in the world. Meanwhile, traditional Chinese medicine (TCM) has been increasingly regarded as a promising and effective alternative therapy approach for patients with depression. Despite many years of research on depression, the current understanding of the pathological mechanism of depression based on TCM theories is still in its infancy. Due to the lack of scientific evidence in the past, TCM is not fully recognized by researchers around the world. This review firstly summarizes the pathogenesis and etiology of depression in terms of both Eastern and Western medical systems. Secondly, it adopts an integrated Eastern and Western approach to propose some plausible neurophysiological pathways linking the liver, spleen, and heart functions explicated in TCM theory. The aim of this theoretical review is to bridge the knowledge gap between Eastern and Western medicine, which may better explain the pathology of depression.
The purpose of this study was to explore the immediate effects of different frequencies of whole-body vibration (WBV) on the performance of trunk muscles of healthy young adults. A group of 30 healthy subjects (15 men; 15 women; age, 26.8 ± 3.74 years; body mass index, 21.9 ± 1.802) participated in the study. Each subject received 3 sessions of vibration exercise with different exercise parameters with frequencies of 25 Hz and 40 Hz and sham stimulation in a random order on different days. Before and after each WBV exercise session, subjects were assessed for trunk muscle strength/endurance tests and trunk proprioception tests. There was a significant increase in trunk extensor strength (p ≤ 0.05) after low-frequency (25 Hz) WBV exercise, but high-frequency (40 Hz) vibration exercise had resulted in a significant decrease in trunk extensor endurance (p ≤ 0.05). Statistical gender difference (p = 0.04) was found for trunk extensor endurance with lower WBV training. No change was noted in the trunk proprioception with different frequencies of WBV. In conclusions, the immediate response of the body to WBV was different for low and high frequencies. Low-frequency vibration enhanced trunk extensor strength, but high-frequency vibration would decrease endurance of the trunk extensor muscles. Males are more sensitive than females in trunk extensor endurance for lower frequency WBV exposure. These results indicated that short-term WBV with low frequency was effective to improve trunk extensor strength in healthy adults, and that could be helpful for relevant activities of trunk extensor performing and preventing sport injury.
