Abstract: BACKGROUND: Existing treatments for patellar tendinopathy need to be further improved. It is of positive significance to explore universal exercise training for patellar tendinopathy in clinical practice. OBJECTIVE: To explore the clinical effect of Baduanjin training combined with shockwave therapy for patellar tendinopathy. METHODS: Patients with patellar tendinopathy were randomly divided into two groups, followed by 4 weeks clinical intervention: shockwave therapy was given in the control group, while Baduanjin training combined with shockwave therapy was given in the trial group. Pain, muscle flexibility, and motor function were assessed using several observational indicators, including Visual Analogue Scale score, time of standing on one foot with closed eyes, knee flexion angle in modified Thomas test, vertical jump state and three-dimensional gait. All the patients were followed up for 1 month in terms of pain assessment. Clinical efficacy of Baduanjin training for patellar tendinopathy was compared between two groups. RESULTS AND CONCLUSION: Findings from the 1-month follow-up showed that Baduanjin training could significantly decrease the Visual Analogue Scale scores of patients patellar tendinopathy (t=-2.744, P < 0.05). After 4 weeks of intervention, Baduanjin training could significantly increase the knee flexion angle in the modified Thomas test (t=2.738, P < 0.05). The standing time of patients with closed eyes was significantly prolonged after Baduanjin training as compared with the shockwave therapy (z=-4.544, P < 0.05). Baduanjin training could increase the hip joint flexion angle (t=2.584, P < 0.05) and the knee joint flexion angle (t'=2.053, P < 0.05). Baduanjin training could decrease the knee extension angle during walking (t=-3.081, P < 0.05). To conclude, Baduanjin training could relieve the pain of patients with patellar tendinopathy, increase the balance stability and muscle flexibility of the lower limbs, improve the power and buffer ability of the lower limbs, reduce the abnormal knee extension during walking, and shorten the time of whole rehabilitation.
