Effect of Eccentric Exercises on Knee Function and Neuromuscular Control of Patellofemoral Pain Syndrome / 中国康复理论与实践

Objective:To investigate the effect of eccentric exercise training on knee function and neuromuscular control in patients with patellofemoral pain syndrome. Methods:From September, 2016 to September, 2019, 39 outpatients with patellofemoral pain syndrome visiting our hospital were randomly divided into control group (n = 19) and experimental group (n = 20). Both groups received routine rehabilitation, while the experimental group received eccentric training of quadriceps femoris in addition, for eight weeks. They were assessed with Visual Analogue Scale (VAS) of pain, Lysholm score, while the acceleration time was measured with Isokinetic Testing and Training System, and stability index with Dynamic Balance Tester. Results:The VAS score, acceleration time of all the muscles, and overall, anterior-posterior and medial-lateral stability indexes decreased (t > 2.521, P < 0.05), and the Lysholm score increased (|t| > 13.628, P < 0.001) in both groups after treatment, while the VAS score, acceleration time of all the muscles, overall and anterior-posterior stability indexes were less (|t| > 2.174, P < 0.05), and the Lysholm score was more (t = 11.947, P < 0.001) in the experimental group than in the control group. Conclusion:Eccentric exercise training of quadriceps femoris is effective on pain, knee function and neuromuscular control for patients with patellofemoral pain syndrome.

Effects of Proprioceptive Trainning on Knee Function and Postural Control for Patients after Anterior Cruciate Ligament Reconstruction / 中国康复理论与实践

Objective:To investigate the clinical effect of proprioceptive trainning on patients after anterior cruciate ligament reconstruction. Methods:From March, 2017 to September, 2018, 30 patients after anterior cruciate ligament reconstruction were randomly divided into control group (n = 15) and experimental group (n = 15). All the patients received routine rehabilitation for eight weeks after operation. Then, the control group received routine rehabilitation, while the experimental group received proprioceptive trainning in addition, for eight weeks. They were assessed with Lysholm score, Isokinetic Testing and Training System, and Dynamic Balance Tester eight and 16 weeks of training. Results:Lysholm score increased in both groups after treatment (t > 16.687, P < 0.001), with decrease of error of knee flexion in 15°, 45° and 75° (t > 2.433, P < 0.05), and speed of centre of gravity moving with eyes closed on stable and unstable floors (t > 2.444, P < 0.05). Compared with the control group, Lysholm score was more (t = 4.150, P < 0.05), errors of knee flexion in 15° and 45° were less (t > 2.710, P < 0.05), and speed of centre of gravity moving with eyes closed on unstable floors was less (P<0.05) in the experimental group. Conclusion:Proprioceptive trainning is effective on proprioception and function of knee after anterior cruciate ligament reconstruction, to improve postural control.

Analysis on the depression status and its associated factors of residents in Anting Town of Shanghai / 上海预防医学

Objective To analyze the depression status and its associated factors of residents in Anting Town of Shanghai.Methods By adopting a multi-stage random sampling method, 2 500 people were selected from among the residents in Anting Town.Questionnaires were independently completed by the residents surveyed and a total of 2 498 valid questionnaires were collected.The depression module for Patient Health Questionnaire (PHQ-9) was used to evaluate depression symptoms.Univariate and multivariate logistic regression analyses were used to analyze the depression status and its associated factors.Results The detection rate of depression symptoms was 4.60% and the main symptom was light depression.Lack of vitality, eating disorders, sleep disorders and loss of enjoyment were among the most frequently-selected items in the univariate evaluation for the depression status.The results of univariate analyses indicated that age, educational level, marital status, self-evaluated health status and average(per person) family monthly income were the factors associated with the depression status.The results of multivariateanalyses indicated that self-evaluated health status and average(per person) family monthly income were the main associated factors.Conclusion The prevalence of depression status for the residents in Anting Town is relatively low.Emphases should be focused on the residents with poor health condition and with the average(per person) family monthly income below 2 000 RMB yuan.
