RESUMO
Introducción: En pacientes con artrosis de rodilla se ha identificado un 30% de asociación de dolor de sensibilización central (DSC). El objetivo es analizar la persistencia de DSC en pacientes tras artroplastia de rodilla y su correlación con la intensidad del dolor, funcionalidad y los factores determinantes asociados, además de evaluar la exploración física como instrumento de valoración. Material y métodos: Estudio cuasiexperimental antes-después de pacientes intervenidos de artroplastia total de rodilla. Se analiza la evolución de variables subjetivas (características del dolor, cuestionarios painDETECT, WOMAC y escala visual numérica) y de exploración física (hiperalgesia térmica, alodinia, hipoestesia, algometría y goniometría), tres meses antes y tres y seis meses después de la cirugía mediante el test de ANOVA de medidas repetidas para las cuantitativas y el Q de Cochran para las cualitativas. Se utilizó la prueba de Spearman para la correlación de los cuestionarios, del PD-Q y variables de exploración y para el modelo multivariante del PD-Q con determinantes clínicos. Resultados: Sesenta y siete pacientes completaron el estudio. La evolución de las variables cuantitativas y cualitativas fue significativa, con correlación entre cuestionarios. En el modelo multivariante lineal de PD-Q se obtuvo relación significativa de antecedentes de limitación movilidad en flexión, dolor musculoesquelético crónico y la asociación de depresión y tiempo. Conclusiones: Un porcentaje significativo de pacientes con artrosis de rodilla tras artroplastia persistieron con probable DSC, correlacionándose con intensidad y funcionalidad. La limitación de movilidad y comorbilidad crónica previas podrían ser determinantes de DSC, siendo la exploración y anamnesis, herramientas útiles en consulta.(AU)
IntroductionIn patients with knee osteoarthritis, a group of 30% has been identified with central pain sensitization (CPS). The aim is to analyze the persistence of CPS in patients after knee arthroplasty and its correlation with pain intensity, functionality, determining factors and to evaluate physical examination as an assessment instrument.Material and methodsQuasi-experimental beforeafter study of patients operated on total knee arthroplasty. The evolution of subjective variables (pain characteristics, painDETECT questionnaire, WOMAC and Numerical Rating Scale) and physical examination (thermal hyperalgesia, allodynia, hypoesthesia, algometry and goniometry) 3 months before and 3 and 6 months after surgery are analysed using repeated measures ANOVA test for the quantitative ones and Cochran's Q for the qualitative ones. Spearmen test was used for the correlation of the questionnaires, the PD-Q and exploration variables and for the multivariate model of the PD-Q with clinical determinants. Results: Sixty-seven patients completed the study. The evolution of the quantitative and qualitative variables was significant, with a correlation between questionnaires. In the linear multivariate model of PD-Q, a significant relationship was obtained from personal history of flexion limitation, chronic musculoskeletal pain and the association between depression and time. Conclusions: A significant percentage of patients with knee osteoarthritis after arthroplasty persisted with probable CPS, correlating with intensity and functionality. The limitation of mobility and previous chronic comorbidity could be determinants of CPS, with anamnesis and exploration being useful tools in consultation.(AU)

OBJECTIVE: To assess the efficacy of percutaneous tibial nerve stimulation and its effectiveness over time in urge urinary incontinence. MATERIALS AND METHODS: We performed a longitudinal, observational, prospective study without a control group that included patients diagnosed with urge urinary incontinence who met the inclusion/exclusion criteria. Patients were treated with 12 sessions of percutaneous tibial nerve stimulation by electroacupuncture. Baseline and post-treatment data were collected from medical records. Patients were assessed by a telephone interview after the treatment. The variables studied were sociodemographic variables, time until interview, the Sandvick and ICIQ-SF questionnaires, daytime urinary frequency, night-time urinary frequency, use of absorbent material and drug treatment. A descriptive analysis of the variables was performed and patient outcomes were analysed with generalised linear mixed models by SPSS v. 25 statistics software. RESULTS: A total of 32 women were included (mean age 58.69±8.96). All variables significantly improved after treatment: Sandvick by 4.38 points (95% CI: 2.68-6.08, P<.001), ICIQ-SF by 8.55 points (95% CI: 5.89-11.22, P<.001), daytime urinary frequency by 2.10 points (95% CI: 1.04-3.16, P<.001) and night-time urinary frequency by 1.31 points (95%CI: 0.58-2.04, P<.001). However, 16.34±9.72 months after treatment, these improvements diminished but without reaching baseline levels. CONCLUSIONS: Percutaneous tibial nerve stimulation by electroacupuncture is effective for the treatment of urge urinary incontinence. Although its effect diminishes over time, the improvement over the baseline situation is maintained during the follow-up period.
