Baduanjin is Better Balance Training Compared to Walking: A Cross-Sectional Study Based on Center of Gravity Trajectories.

Background:  It has already been demonstrated by previous studies that Baduanjin training can improve the body's balance. However, its biomechanical mechanism remains unknown. Center of gravity (COG) trajectory analysis is an essential biomechanical test to explore the balance ability of the human body.

Mechanical mechanism of suture passer needle break in rotator cuff repair.

Introduction: Suture passer needle, as one of commonly used instrument in the arthroscopic rotator cuff repair, often breaks at the notch of the needle, which originally was designed to facilitate suture with thread. Our study aimed to evaluate the suture failure rate and stitch success rate between intact suture needle and broken needle and explore the mechanism of the needle breakage and achieving better future designs.

Materials And Methods: From 2017 to 2021, consecutive 437 shoulders (11 cases were bilateral) underwent arthroscopic repair for full-thickness rotator cuff tear at the authors' institution.

The effect of hip abductor fatigue on knee kinematics and kinetics during normal gait.

Objective: To investigate the effect of hip abductor fatigue on the kinematics and kinetics of the knee joint during walking in healthy people to provide a new approach for the prevention and treatment of knee-related injuries and diseases.

Methods: Twenty healthy participants, ten females, and ten males, with a mean age of 25.10 ± 1.

Expert consensus on protocol of rehabilitation for COVID-19 patients using framework and approaches of WHO International Family Classifications.

Coronavirus disease 2019 (COVID-19) has widely spread all over the world and the numbers of patients and deaths are increasing. According to the epidemiology, virology, and clinical practice, there are varying degrees of changes in patients, involving the human body structure and function and the activity and participation. Based on the World Health Organization (WHO) International Classification of Functioning, Disability and Health (ICF) and its biopsychosocial model of functioning, we use the WHO Family of International Classifications (WHO-FICs) framework to form an expert consensus on the COVID-19 rehabilitation program, focusing on the diagnosis and evaluation of disease and functioning, and service delivery of rehabilitation, and to establish a standard rehabilitation framework, terminology system, and evaluation and intervention systems based the WHO-FICs.

Intestinal microbiota composition in patients with amyotrophic lateral sclerosis: establishment of bacterial and archaeal communities analyses.

Background: Emerging evidences have indicated that the composition of gut microbiota was significantly influenced by central nervous system diseases. The digestion and metabolism disturbances of patients with amyotrophic lateral sclerosis (ALS) might be strongly associated with ALS; however, this has rarely been evaluated in these populations. This study was to evaluate bacterial and archaeal composition of gut flora and the corresponding metabolism performance of these micro-organisms in fecal samples of patients with ALS.

Generation of a Movement Scheme for Positive Training.

Rehabilitation robots have been demonstrated to be an efficient tool in the field of rehabilitation training. Meanwhile, there are varieties of tasks designed for motion training. These tasks need to be transmitted to motion data for rehabilitation robots.

Heliangin inhibited lipopolysaccharide-induced inflammation through signaling NF-κB pathway on LPS-induced RAW 264.7 cells.

The heliangin is a natural agent mainly isolated from Helianthus tuberosus L. (Asteraceae). In order to investigate the anti-inflammatory effect of heliangin, several typical models in vivo and in vitro were performed.

Contribution of arm swing to dynamic stability based on the nonlinear time series analysis method.

It is human nature to swing their arms at the frequency of leg motion during walking, but the contribution of arm swing to dynamic stability of human motion segments was poorly understood. Based on the nonlinear time series analysis method, the objective of this study was to investigate the effects of arm swing in three conditions (natural, active and restricted arm swing) on the dynamic stability of spine and lower extremity joints, and to further assess the contribution of arm swing to the human dynamic stability in relation with age. Gait experiments were carried out for 10 young and 8 middle-aged healthy volunteers while walking with natural, active and restricted arm swing.

Effects of Baduanjin () exercise on knee osteoarthritis: a one-year study.

Objectives: Knee osteoarthritis (OA) is a major cause of pain and functional limitation. Short-term Baduanjin () exercise had been testified to be beneficial to the disease. This study conducted an initial assessment of the one-year Baduanjin exercise on knee OA.

New variables for measuring joint space width to evaluate knee osteoarthritis.

Background: Assessing the radiographic features of knee osteoarthritis (OA), especially joint space narrowing, is important for evaluating disease progression. The purpose of this study was to quantitatively analyze joint space narrowing by measuring 2 new variables: the average joint space width (aJSW) and the articulate angle (AA) on X-ray films, and to evaluate the relationship between the 2 variables, knee function and OA symptoms.

Methods: Using the web-based radiology viewer (Cedara I-Reach™ 4.

Berberine inhibits lipopolysaccharide- and polyethylene particle-induced mouse calvarial osteolysis in vivo.

Background: Wear particle-induced osteolysis could lead to the aseptic loosening of implants. Studies have suggested that endotoxins, such as lipopolysaccharides (LPS), may be the primary causes of wear particle-mediated osteolysis, and that osteolysis may originate from subclinical levels of bacterial infection. However, effective therapies against wear particles and gram-negative bacterial or LPS-induced bone resorption are limited.

Tetracyclines inhibit rat osteoclast formation and activity in vitro and affect bone turnover in young rats in vivo.

An experiment was designed to investigate whether systemic administration of tetracyclines (TCs) as bone fluorochrome labels could interfere with bone modeling in vivo and inhibit osteoclast formation and activity in vitro. Cell cultures of rat bone marrow macrophages revealed that TC and oxytetracycline inhibited osteoclastogenesis and bone resorption and stimulated apoptosis. Forty rats in five groups were treated with saline, calcein green, alizarin red S, TC, or oxytetracycline.

Baduanjin alleviates the symptoms of knee osteoarthritis.

Objectives: To assess the feasibility and safety of using the health-promoting traditional Chinese exercise, known as Baduanjin, in treating knee osteoarthritis (OA).

Subjects: Twenty-eight (28) female patients who met the American College of Rheumatology criteria for osteoarthritis of the knee signed the informed consent and were randomized into the Baduanjin group (n=14) and the control group (n=14). Eleven (11) patients in the Baduanjin group and 10 patients in the control group completed the trial.

[The creation of laosun yutie plaster and safety experiment].

Objective: To create an externally-applied TCD plaster (Laosun Yutie plaster) for the lumbar muscle strain (LMS).

Method: (1) The raw material such as angelica, safflower, frankincense, myrrh, clove and so on were turned into solid TCD plaster by a serial of modern treatment technology-distillation, extraction, condense, dehydration. Meanwhile, the naphtha from the distillation process and borneol were dissolved into ethanol solution and the dilution was thus made; (2) The solid TCD plaster and the dilution from the aboved-mentioned process were put together to form the TCD plaster and the corresponding safety experiments were applied to rabits' skin.
