Objective To determine the effects of Taijiquan practice on knee proprioception in patients with knee osteoarthritis (OA). Methods We conducted a randomized controlled trial comparing Taijiquan with a control condition (wellness education) in patients with knee OA. The patients participated in either a 60-min Taijiquan session three times weekly or a 60-min weekly educational session, for 24 consecutive weeks. The primary outcomes were changes in knee proprioception. Secondary outcomes were changes in the Western Ontario and McMaster University Osteoarthritis Index (WOMAC). Results After 24 weeks, compared with the control group, the Taijiquan group demonstrated better improvements in the joint position sense in knee flexion (left: −2.12°; right: −2.02°), and knee extension (left: −2.22°; right: −1.54°). In addition, the Taijiquan group showed significantly greater improvements in the WOMAC scores (P Conclusion A 24-week Taijiquan practice resulted in a significant improvement in knee proprioception in patients with knee OA. The present findings add increasing evidence regarding the clinical benefits of Taijiquan as a therapeutic modality for patients to improve the reflex protection of knee joints against potentially harmful forces.

Objective Chinese massage (Tui Na) is one of the most popular Traditional Chinese Medicine remedies for knee osteoarthritis (OA). Several studies have subjectively evaluated the effect of Chinese massage on knee OA through self-assessment questionnaires; however, very few studies have objectively assessed the effect by measuring knee muscle strength. The purpose of this study was to assess the efficacy of Chinese massage in improving knee extensor and flexor muscle strength in patients with knee OA. Methods Thirty patients with knee OA received Chinese massage therapy three times per week for 2 weeks. Patients completed pre- and post-treatment Visual Analogue Scale (VAS) pain questionnaires, and pre- and post-treatment knee muscle strength was evaluated using the Biodex Multi-Joint System 3. Isokinetic muscle strength measurements were performed at 60 degrees/s and 180 degrees/s. The peak torque (PT), peak torque/body weight (PT/BW), total work (TW), average power (AP), hamstring/quadriceps (H/Q), and range of motion (ROM) values were recorded separately for flexors and extensors. Results Chinese massage therapy significantly improved knee pain as assessed by the VAS in patients with knee OA (P < 0.05). Post-treatment values were significantly greater than pre-treatment values in the extensor muscles for PT (right P = 0.013, left P = 0.001), PT/BW (right P = 0.008, left P = 0.001) and TW (right P = 0.036, left P = 0.004) at 60 degrees/s. The AP increased significantly after treatment in the flexor muscles in the right knee (P = 0.009) and the extensor muscles in the left knee (P = 0.001). There were no significant differences in pre- and post-treatment ROM and H/Q at 60 degrees/s and 180 degrees/s. Conclusion Chinese massage therapy decreased pain and may improve extensor muscle strength in patients with knee OA, but does not appear to improve ROM.

The objective of this study was to evaluate the effectiveness of Chinese massage therapy in patients with knee osteoarthritis (OA) by measuring lower-limb gait parameters. We recruited 20 women with knee OA, who then underwent Chinese massage therapy three times per week for 2 weeks. The patients underwent gait evaluation using a six-camera infrared motion analysis system. They completed Western Ontario and McMaster Universities Osteoarthritis Index questionnaires before and after treatment. We calculated the forward speed, step width, step length, total support time percentage, initial double support time percentage, and single support time percentage. We also measured the angles at the knee, hip, and ankle during the stance phase of walking. The results showed statistically significant mean differences in knee pain relief, alleviation of stiffness, and physical function enhancement after therapy (P < 0.05). The patients gained significantly faster gait speed, greater step width, and increased total support time percentage after the Chinese massage therapy (P < 0.05). There were no significant differences in the range of motion or initial contact angles of the knee, hip, or ankle during the stance phase of walking. We concluded that Chinese massage is a beneficial complementary treatment and an alternative therapy choice for patients with knee OA for short-term pain relief. Chinese massage may improve walking ability for these patients.
