[en] Objective. To know the avaliable evidence on the neuromuscular alterations in the gluteus muscles in adults with chronic low back pain. Material and methods. Searchs were performed in the data bases Pubmed, Scopus, Web of Science and SportDiscus. The selection criteria were determined according to types of participants, types of studies, neuromuscular alterations, language and chronological coverage. Key words were grouped in 3 blocks: a) back pain: "Low Back Pain"; b) gluteus muscles: "Buttocks", "Gluteus maximus", "Gluteus medius"; c) neuromuscular alterations: "Electromyography", "Feedback, Sensory", "Muscle Strength", "Muscle Weakness", "Muscular Diseases", "Proprioception", "Musculoskeletal and Neural Physiological Phenomena", "altered muscular activation", "neuromuscular patterns", "motor control". Study variables were classified according to type of study, participants characteristics, neuromuscular alterations of gluteus muscles and the type of tool used to identify alterations. The RefWorks program was used for bibliographic management. Methodological quality assessment of articles was performed according to Oxford scale criteria and the magazines impact factor was performed according to JCR/SJR. Outcomes. 12 items were selected, of which 11 were cross-sectional case-control studies and 1 cross-sectional study of a cohort. Most of studies used EMG as a recording tool to measure neuromuscular dysfunctions. The outcomes of the déficits of activation, delay in activation and fatigue of gluteus muscles in patients with chronic low back pain are inconclusive. On the contrary, it has been demonstrated that the gluteus medius has a weakness in these patients. Discussion/ conclusions. In general, studies that analyze the neuromuscular dysfunctions of the gluteous muscles give heterogeneous and inconclusive results.

[gl] Obxetivo. Coñecer a evidencia dispoñible sobre as alteracións neuromusculares que se presentan na musculatura glútea nos adultos con dor lumbar crónico. Material e métodos. Se realizaron búsquedas nas bases de datos PubMed, SportDiscus, Scopus e Web of Science. Os criterios de selección se determinaron según o tipo de participantes, tipo de estudos, alteracións neuromusculares, idioma e cobertura cronolóxica. As palabras clave utilizadas foron agrupadas en 3 bloques: a) dor lumbar: "Low Back Pain"; b) musculatura glútea: "Buttocks", "Gluteus maximus", "Gluteus medius"; c) alteracións neuromusculares: "Electromyography", "Feedback, Sensory", "Muscle Strength", "Muscle Weakness", "Muscular Diseases", "Proprioception", "Musculoskeletal and Neural Physiological Phenomena", "altered muscular activation", "neuromuscular patterns", "motor control". As variables de estudo se clasificaron segundo o tipo de estudo, as características dos participantes, as alteracións neuromusculares da musculatura glútea e o tipo de ferramenta utilizada para identificar as alteracións. Para a xestión bibliográfica empregouse o programa Refworks. A valoración da calidade metodolóxica dos artígos realizouse en base aos criterios da escala Oxford e se evaluou o factor de impacto das revistas segundo o JCR/SJR. Resultados. Foron seleccionados 12 artigos, dos cales 11 eran estudos transversales de casos e controis e 1 transversal de una cohorte. A mayoría dos estudos utilizan a EMG como ferramenta de rexistro para medir as disfuncións neuromusculares. Os resultados sobre os déficits de activación, retraso na activación e fatiga na musculatura glútea en pacientes con dor lumbar cronico son inconclusos. Polo contrario, demostrouse que o glúteo medio presenta debilidade nestos pacientes. Discusión/conclusións. En xeral, os estudos que analizan as disfuncións neuromusculares da musculatura glútea presentan resultados heteroxéneos e inconclusos.
