太极拳治疗膝骨关节炎生物力学机制的范围综述OA

Objective:This review examines the application and mechanisms of Tai Chi(TC)in the treatment of knee osteoarthritis(KOA)from a biomechanical perspective,clarifying its effects on indicators such as gait,joint load,and muscle activity,with the aim of providing guidance for clinical practice.Methods:Following the PRISMA-ScR and JBI Scoping Review Methodology Framework,we searched PubMed,Embase,the Cochrane Library,Web of Science,China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP Information,and the Chinese Biomedical Literature Database for relevant literature on the biomechanical application of Tai Chi interventions for knee osteoarthritis.The literature was screened,summarized,extracted,and analyzed according to inclusion and exclusion criteria,with data extracted and a scoping review conducted.The Physical Therapy Evidence Database(PEDro)scale was used to assess the quality of the literature.Results:A total of 11 studies were included,with 9 from China,1 from the United States,and the remaining 1 from a collaborative study between the two countries.These studies involved 591 patients with knee osteoarthritis(KOA),with publication dates ranging from 2008 to 2024.The quality scores of the included studies were predominantly between 4 and 7 points.The study types included 7 randomized controlled trials(RCTs),3 mixed-method studies,and 1 self-controlled study.The intervention protocols primarily involved self-adapted or modified versions of Tai Chi,with two studies not specifying the specific style or form.The intervention frequency ranged from 2 to 14 sessions per week,with each session lasting over 20 minutes,and the total intervention duration ranged from 6 to 24 weeks.Biomechanical outcome measures varied significantly across studies,with a total of 32 different measures reported,and only a few studies monitored core indicators such as knee adduction moment(KAM).Intervention effects showed that Tai Chi interventions had varying degrees of positive impact on gait spatiotemporal parameters,joint kinematic parameters,muscle activity,plantar pressure,and quality of life in KOA patients.Conclusion:Tai Chi improves gait function and joint stability in patients with knee osteoarthritis by regulating lower limb biomechanical load and optimizing muscle coordination.It is recommended that clinical medical staff develop reasonable,personalized exercise intervention plans based on clinical situations and implement scientific,structured exercise management.
