The multifactorial etiology of the syndrome makes the clinical evaluation and synthesis of an effective treatment plan particularly demanding and difficult. The absence of a specific clinical trial for the diagnosis or rejection of PFPS leads to the diagnosis of the syndrome through the careful rejection of other conditions with similar symptoms. Physiotherapy is based on the management and immediate treatment of the patient’s pain, by combining active and passive means of treatment and address the fear of exercise and movement. Interventions for the treatment of patellofemoral pain present positive short-term but not as encouraging long-term results. Therefore we are posed with an interesting question: what is the most effective treatment plan for the management of PFPS? The purpose of the review is to present the necessary and most up-to-date data for the identification, clinical evaluation and etiology of the syndrome as well as to compose in the form of guidelines (Guidelines) the basis for building an effective treatment plan for the treatment of PFPS.展开更多
Density(p),speed of sound(u),viscosity(η),and refractive index(n_(D))were measured for pure acetonitrile,trichloroethene,and tetrachloroethene,as well as their binary mixtures at temperatures T=(293.15,298.15,303.15)...Density(p),speed of sound(u),viscosity(η),and refractive index(n_(D))were measured for pure acetonitrile,trichloroethene,and tetrachloroethene,as well as their binary mixtures at temperatures T=(293.15,298.15,303.15)K and at ambient pressure(81.5 kPa).From the experimental data,excess molar volume(V_(m)~E),thermal expansion coefficients(α),deviations in isentropic compressibility(Δκ_(S)),viscosity(Δ_η),and refractive index(Δn_(D))were calculated.These values were then correlated using the Redlich-Kister polynomial equation,with fitting coefficients and standard deviations determined.Additionally,the Prigogine-Flory-Patterson(PFP)theory and the Extended Real Associated Solution(ERAS)model were employed to correlate the excess molar volume,while the Perturbed Chain Statistical Associating Fluid Theory(PC-SAFT)was used to predict the density of mixtures.展开更多

Methods Sixty cases of PFP at different stages were divided into a treatment group and a control group according to the sequence for visit, and 30 patients were included in each group. The patients in the treatment group were treated by using drugs, acupuncture （shallow puncture and subexcite） and microwave therapy during the acute stage, and they were subjected to electroacupuncture （EA） （heavy stimulation and penetration needling）, acupoint injection, electrotherapy and massage during the convalescence stage. In contrast, the patients in the control group were treated simply with drugs, and the therapeutic methods during the convalescence stage were the same to those for the treatment group, and the therapeutic effect of the two groups was observed after three treatment courses. Results The total effective rate in the treatment group was 100.0% （30/30）, the cured rate after one treatment course was 48.2% （13/27）, the cured rate after two treatment courses was 44.4% （12/27）, and the cured rate after three treatment courses was 7.4% （2/27）. The total effective rate in the control group was 90.0% （27/30）, the cured rate after one treatment course was 5.5% （1/18）, the cured rate after two treatment courses was 27.8% （5/18）, and the cured rate after three treatment courses was 66.7% （12/18）. The therapeutic effect and the treatment courses for healing of the treatment group were significantly better than those in the control group （P0.05）. Conclusion the therapeutic effect of different therapeutic methods on PFP is remarkable.展开更多
