“…TC forms commonly used in prior studies were chosen without specifying a measurable and objective criterion [ 12 , 15 ], which may lead to inconsistent or sub-optimal effects in reducing the risk of falls. Our previous results showed that individual TC forms are associated with different levels of the range of stability, implying various challenges in maintaining body balance [ 6 ]. Such information provides us a valuable and objective framework to choose the best TC forms from the perspective of improving balance.…”

“…The collection and processing of the data used here can be found elsewhere [ 6 ]. Briefly, eight older adults with knee OA (mean ± standard deviation age: 62.8 ± 12.2 years; body height: 1.62 ± 0.17 m; and body mass: 81.3 ± 28.5 kg) learned how to correctly perform 24-form simplified Yang's TC under the instructions of an experienced TC instructor on an individual basis.…”

“…To address this knowledge gap, we recently conducted a study to examine dynamic stability of the human body when performing each simplified Yang's TC form among older adults with knee OA [ 6 ]. Dynamic stability is a comprehensive measurement of the relative kinematics between the human body's center of mass (COM) and base of support (BOS).…”

“…It has been broadly used to quantify the body's dynamic balance [ 7 , 8 ]. The results indicated that dynamic gait stability in the sagittal and frontal planes varies drastically among TC forms [ 6 ]. The range of dynamic stability is also significantly different between TC forms.…”

“…The unique coordinated movements of tai chi are associated with significant effects on improving strength and endurance of the skeletal muscle and ameliorating proprioception and neuromuscular control function in older adults [2][3][4]. Previous studies have found that implementation of the push hands and wild horse's mane techniques of tai chi could be an optimal strategy to improve balance and prevent falls [5][6][7]. Compared with high pose, low-pose tai chi can elicit greater energy consumption and muscle activity [8,9], thus leading to better exercise efficiency.…”

Background. Tai chi is recognized worldwide for its rehabilitation abilities and healthcare benefits. However, in recent years, some movements associated with tai chi have been shown to damage the lower limb joints. The purpose of this study was to investigate and compare the effects of different movements, postures, center of mass (COM) movements, and range of knee movement of tai chi exercises on knee joint load. Methods. Fourteen professional tai chi practitioners in two postures (high and low) were enrolled to perform the following four typical tai chi movements: wild horse’s mane (WHM), repulse monkey (RM), wave-hand in cloud (WHIC), and grasp the bird’s tail (GBT). Kinematic and kinetics data were synchronously collected using the Vicon infrared high-speed motion capture system and a three-dimensional (3D) force measurement platform. Variance analysis and partial correlation analysis were performed to investigate factors influencing peak knee joint moment and vertical ground reaction force (VGRF). Results. The results showed that the peak knee extension and abduction moment were larger in WHM and RM than those in WHIC and GBT ( p < 0.05 ). WHM was associated with greater rotation moment than the other typical movements ( p < 0.05 ). VGRF and joint moment among different poses were significantly different. Low-pose tai chi typical movements were associated with greater VGRF, knee joint extension and abduction, and rotation moments than high-pose movements ( p < 0.05 ). The anteroposterior and mediolateral COM displacements were strongly and positively associated with VGRF ( p < 0.001 ), while the mediolateral COM displacement was negatively associated with knee extension moment ( p < 0.001 ). The knee internal-external rotation ROM and anteroposterior and mediolateral COM displacements were positively associated with knee abduction moment ( p < 0.01 ). Conclusion. For long-term tai chi exercises, choosing a suitable posture based on an individual exercise level and reasonable control of knee ROM and COM displacement can reduce the risk of knee injury during exercise.

Knee joint osteoarthritis, a chronic condition resulting in considerable disability, particularly in later life, not only impacts life quality significantly and severely, but is also strongly associated with the persistence of intractable pain, depression, helplessness, and a high falls injury risk. This narrative overview synthesizes the knowledge base regarding painful knee osteoarthritis and what is known about Tai Chi exercise participation in the context of reducing knee joint disability and its associated risk of one or more injurious falls, as well as pain and depression. To this end, all relevant articles published in the English language on the topic were sought. While most reports rely on Eastern observations, rather than Western medicine studies, collectively, these data reveal that Tai Chi practiced widely in Asia for many centuries may have an enormous positive impact on reducing distress and increasing function and autonomy among older adults living in the community and diagnosed as having knee osteoarthritis. They specifically suggest the increasing numbers of older adults diagnosed as having knee osteoarthritis can safely practice selected Tai Chi exercises with the expectation that consistent applications will enhance mobility, reduce pain and depression, plus instability and possible injurious falls, while reducing fatigue, even if surgery is forthcoming.
