RESUMO

Accurate evaluation of physical function in patients undergoing haemodialysis is crucial in the analysis of the impact of exercise programs in this population. The aim of this study was to evaluate the reproducibility of several physical functional tests, depending on the timing of their implementation (before the HD session vs. non-HD days). This is a prospective, non-experimental, descriptive study. Thirty patients in haemodialysis were evaluated twice, 1 week apart. The test session was performed before the haemodialysis session started and a retest was performed in non-dialysis day. The testing battery included the short physical performance battery, sit-to-stand tests, 6 min walk test, one-leg stand test, timed up and go, and handgrip strength with and without forearm support. The intra-rater reproducibility was determined by the intraclass correlation coefficients and the agreement was assessed by Bland-Altman analysis. The intraclass correlation coefficients values ranged from 0.86 to 0.96, so that all tests showed good to very good relative reliability. The mean differences between trials of sit to stand 10 and 60, timed up and go and all the handgrip tests were close to zero, indicating no systematic differences between trials. Large range of values between trials was observed for the 6 min walk test, gait speed, one-leg stand test and short physical performance battery, indicating a systematic bias for these four tests. In conclusion,  the sit to stand 10 and 60, timed up and go and handgrip tests had good to excellent test-retest reliability in measuring physical function in different dialysis days of patients undertaking haemodialysis. The minimal detectable change values are provided for this population. Bias were found for the 6 min walk test, gait speed, Short physical performance battery or one-leg stand test when the testing day changed.

RESUMO

Introducción: Cada vez es más frecuente promocionar programas de ejercicio físico en pacientes en hemodiálisis. Se puede valorar la condición física de estos pacientes y el resultado de dichos programas con diferentes pruebas funcionales. Objetivo: Valorar la fiabilidad en términos de concordancia interobservador de las mediciones de capacidad funcional y fuerza muscular en pacientes en hemodiálisis. Material y Método: 30 pacientes en hemodiálisis realizaron una batería de pruebas funcionales en dos fases: Short Physical Performance Battery, equilibrio estático monopodal, Timed Up and Go, Test Sit-to-stand-To-Sit-5, Sit-to-stand-To-Sit-10, Sit-to-stand-To-Sit-60, fuerza de tríceps sural, 6 minutos marcha y dinamometría de la mano. Resultados: El índice de correlación intraclase para la fiabilidad interobservador fue para el test Sit-to-stand-To-Sit-5: 0,779; velocidad en 4 metros: 0,820; puntuación total Short Physical Performance Battery: 0,807; Sit-to-stand-To-Sit-10: 0,908; Sit-to-stand-To-Sit-60: 0,865; 6 minutos marcha: 0,897; Equilibrio monopodal: 0,925; Timed Up and Go: 0,918; Fuerza de tríceps sural derecho: 0,702; Fuerza de tríceps sural izquierdo: 0,995; dinamometría mano derecha con apoyo: 0,952; dinamometría mano izquierda con apoyo: 0,897; dinamometría mano derecha sin apoyo: 0,973; dinamometría mano izquierda con apoyo: 0,964. Conclusiones: La fiabilidad interobservador en la mayoría de las pruebas es alta, por lo que se puede aceptar que la valoración del estado funcional del paciente y de los resultados de los programas destinados a promocionar el ejercicio lo lleven a cabo diferentes observadores experimentados, lo que facilitaría el seguimiento de los pacientes


Introduction: It is increasingly common to promote physical exercise programs in hemodialysis patients. The physical condition of patients and the result of these programs with different functional tests can be assessed. Objective: To assess the reliability in terms of interobserver reliability of functional capacity and muscle strength measurements in hemodialysis patients. Material and Method: 30 patients on hemodialysis performed several functional tests in two phases: Short Physical Performance Battery, static monopodal equilibrium, Timed Up and Go, Test Sit-to-stand-To-Sit-5, Sit-to-stand-To-Sit-10, Sit-to-stand-To-Sit-60, strength of triceps sural, 6 minutes walking and dynamometry of the hand. Results: The intraclass correlation coefficient for interobserver reliability was for the Sit-to-stand-To-Sit-5 test: 0.779; speed in 4 meters: 0.820; Total score Short Physical Performance Battery: 0.807; Sit-to-stand-To-Sit-10: 0.908; Sit-to-stand-To-Sit-60: 0.865; 6 minutes march: 0.897; Monopodal equilibrium: 0.925; Timed Up and Go: 0.918; Right triceps sural force: 0.702; Left triceps sural force: 0.995; Right hand dynamometry with support: 0.952; Left hand dynamometry with support: 0.897; right hand dynamometry without support: 0.973; left hand dynamometry with support: 0.964. Conclusions: The interobserver reliability, in most tests is high, so it can be accepted that the assessment of the patient’s functional status and the results of the programs designed to promote the exercise is carried out by different experienced observers, which would facilitate the follow-up of patients

RESUMO

Introducción: La capacidad funcional disminuida y la importante atrofia muscular caracterizan a los pacientes en hemodiálisis (HD). El ejercicio físico intradiálisis y recientemente la electroestimulación neuromuscular (EMS), representan dos serias opciones terapéuticas para mejorar esta deteriorada condición física. Actualmente, no existen estudios publicados sobre el papel de la EMS y la composición corporal en los pacientes en HD. Objetivo: Analizar que efecto produce un programa de EMS sobre la fuerza muscular, capacidad funcional, parámetros nutricionales y composición corporal en nuestros pacientes en HD. Material y Métodos: Estudio unicéntrico, prospectivo de 12 semanas de duración. Los pacientes incluidos realizaron un programa adaptativo de EMS en ambos cuádriceps intradiálisis mediante el dispositivo Compex R Theta 500i. Analizamos: 1.- Parámetros nutricionales (Albumina, pre albúmina, triglicéridos, colesterol total y fracciones, ferritina y Proteína C reactiva). 2.- Datos musculares: Composición muscular cuadriceps, Fuerza extensión máxima cuádriceps (FEMQ) y handgrip (HG) brazo dominante. 3.- Test funcionales: “Sit to stand to sit” (STS10) y “six- minutes walking test” (6MWT). 4.- Composición corporal mediante biompedancia electrica (BIA). Resultados: 13 pacientes incluidos: (69.2% hombres). Edad media: 65.7 años y 33.9 meses en HD. I.Charlson medio 9.1. La principal etiología de la ERC fue la DM ( 38.5%). Al final del estudio se observó una mejoría en (*p<0.05): FEMQ* ( 11.7±7.1 vs 13.4±7.4 Kg), STS10 (39.3±15.5 vs 35.8±13.7 seg), 6MWT* (9.9%, 293.2 vs 325.2 m). En relación a la composición corporal, se observó únicamente un aumento significativo del área muscular (AMQ*: 128.6 ± 30.2 vs 144.6 ± 22.4 cm2) y una disminución del área grasa (AGQ*: 76.5 ± 26.9 vs 62.1 ± 20.1 cm2) a nivel quadricipital, sin cambios en el resto de datos analizados (% grasa abdominal, peso graso, peso magro, agua corporal total). No se objetivaron cambios relevantes en los parámetros nutricionales y de adecuación dialítica. Conclusiones: 1.- La electroestimulación neuromuscular intradialísis mejoró la fuerza muscular, la capacidad funcional y la composición muscular del cuadriceps de nuestros pacientes en HD. 2.- Nuestros resultados remarcan el carácter local de la electroes-timulación neuromuscular, dada la ausencia de cambios relevantes en el resto de los parámetros nutricionales y datos corporales analizados. 3.- No obstante, son necesarios futuros estudios mejor diseñados, de cara a discernir si la electroestimulación neuromuscular podría ser una nueva alternativa terapéutica para evitar la atrofia muscular y el deterioro progresivo de la condición física de éstos pacientes (AU)


Background: The reduced functional capacity and significant muscle atrophy characterized patients on hemodialysis. Intradialytic exercise and recently neuromuscular electrostimulation (EMS) represent two serious therapeutical options to improve the deteriorated physical condition. Until date, there are no published studies about the role of EMS and body composition in HD patients. Objectives: Analyze the effect a program of EMS on muscle strength, functional capacity, nutritional parameters and body composition in our HD patients. Methods: A 12 weeks single-center, prospective study. Patients included in the study performed an intradialysis EMS adaptive program in both quadriceps using the Compex R Theta 500i device. We analyzed: 1.- Nutritional parameters (albumin, pre-albumin, triglycerides, total cholesterol and fractions, ferritin and C-reactive protein). 2.- Muscular data: Muscular composition, Maximum length quadriceps strength (MLQS) and “hand-grip” (HG) dominant arm. 3.- Functional capacity test: “Sit to stand to sit” (STS10) and “six- minutes walking test” (6MWT). 4.- Body composition. Results: 13 HD patients included: 69.2 % men. Mean age 65.7 years and 33.9 months on HD. A significant (* p < 0,05) improvement was observed in MLQS* (11.7±7.1 vs 13.4±7.4 Kg), STS10* (39.3±15.5 vs 35.8±13.7 seg), 6MWT* (9.9%, 293.2 vs 325.2 m). There was a signi-ficant increase in the quadriceps muscular area (QMA*: 128.6 ± 30.2 vs 144.6 ± 22.4 cm2) and decrease of fat quadricipital area (FQA*: 76.5 ± 26.9 vs 62.1 ± 20.1 cm2). No significant changes were observed in nutritional parameters, body composition (body fat percentage, lean and fat mass, total body water) or dialysis adecuacy data. Conclusions: 1.- Intradialysis quadriceps EMS improved muscle strength, functional capacity and the quadriceps muscle composition in our HD patients. 2.- Our results underline the local aspects on EMS, given the absence of relevant changes on nutritional parameters and body composition. 3.- Future studies are manadatory in order to establish if EMS could be a new alternative to prevent muscle atrophy and the progressive deterioration of the physical condition of these patients (AU)
