“…Researches showed that the peak ground reaction force (GRF) during Brush Knee and Twist Step was 98% of body weight, which was smaller than the load experienced during walking (121%) and jogging (187%). (31) The GRF data are essential for quantifying joint movement and loading rate. Researches showed that Tai Chi movements generate lower peak GRF and loading rate compared with walking.…”

Osteoarthritis (OA) is the most prevalent form of arthritis, and the most commonly influenced appendicular joints are knees, hips and fi ngers. (1) The muscle atrophy, cartilage degradation, joint instability and synovial inflammation lead to compromised physical function and pain. (2) Tai Chi involves slow and gentle motions to be particularly suitable to arthritic individuals and is easy to persist since they are costeffective and commonly homebound.As an important part of traditional Chinese exercise (TCE), Tai Chi is a type of mind-body practice that consists of a series of graceful, fl owing movements combined with deep diaphragmatic breathing, relaxation and meditation. (3) With a history of over 400 years, Tai Chi has evolved into various styles and schools that share some basic principles. (4) The non-competitive and self-paced features of Tai Chi make it a unique, feasible way for people to nurture physical and mental well-being. Rigorous and objective evidence supported the mental and physical effi cacy of Tai Chi for patients with lower limb OA. (5)(6)(7)(8) The physical component promotes muscular strength, proprioception, flexibility, postural control, and gait performance, and the mind component improves psychological health and life satisfaction.Application of biopsychosocial model continues to be known as a useful way to understand the physical impairments, psychological distress and social factors for management of OA. (9) According to the World Health Organisation's International Classification of Functioning, Disability, and Health (ICF), body functions, activity and participation are important components of health condition. (10) The ICF core sets for the component "body functions" in OA include a list of categories such as muscle power functions, joint functions, sensation of pain and sleep functions. (10) Even if the domain "infl ammation" is not ICF based, it plays a critical role in the pathophysiological process of OA. The aims of this review are to present a biopsychosocial framework summarizing the health benefi ts of Tai Chi in lower limb OA patients and trying to disentangle the mechanisms that potentially underlie these favourable effects.

Tai chi is considered both a martial art and a series of low impact exercises. It is also a tool in the toolbox of traditional Chinese medicine (TCM) that has been in existence for hundreds of years. Qigong is also a set of low impact, gentle exercises that have been in existence for thousands of years and is also considered a tool in the TCM toolbox. The present article reviews some studies on the treatment of arthritis that have used tai chi or qigong exercises. The reference section includes an extensive list of publications for further research.

“…Inclusion criteria were 60-80 years of age, hip pain for 3 months or more, radiographically verified hip OA (Danielson criteria). Before the initiation of this study, a priori power analysis using the data from the previous study (Li et al, 2019; β = 0.20; α = .05) revealed that 12 subjects were needed to observe biomechanical differences between BKTS and walking. X-ray examination of the participants revealed mild hip OA (Kellgren Lawrence scale = 1, 2).…”

“…There is little research regarding the effects of Tai Chi on the contact stress inside the hip and knee joints. Recently, Li et al (2019) have studied the effect of typical Tai Chi movement on the contact stress in the knee joint using finite element (FE) method, while the contact stress inside the hip joint is still unknown.…”

“…The purpose of this study is to analyze the biomechanical effects of BKTS on the hip joint and provide some reference for the clinical trial of the effect of Tai Chi on hip OA. According to a recent study on the knee joint (Li et al, 2019), we hypothesize that BKTS would provide lower contact stress of the hip joint, a lower muscle force, a larger ROM, and lower joint reaction force than walking.…”

There is little research related to the biomechanical effects of Tai Chi on the hip joint. This study was aimed to analyze the biomechanical characteristic of a typical Tai Chi movement, Brush Knee and Twist Step. A total of 12 experienced older men voluntarily participated in this study. Each participant was requested to perform standard Brush Knee and Twist Step and normal walking. The scaled-generic musculoskeletal model of each participant was developed. A finite element model of the hip joint and pelvis was established and validated. Data from each trail were input to the model for simulation, and the biomechanics were compared between Brush Knee and Twist Step and walking. Compared with walking, Tai Chi may have better improvement in the range of motion of the hip joint and the coordination of the neuromuscular system under safer condition. It is suitable for patients with hip osteoarthritis and the older adults with severe muscle loss, and clinical studies are required to confirm it further.
