“…However, we observed a clear correlation between overweight and obese patients (average BMI of 30, mild obesity) and high activation in the abdominal musculature (81.5%). This correlates with that described by Jiménez et al, 24 who investigate factors that impact fusion in the treatment of lumbar spine stability, such as obesity, alcoholism, smoking, age, sex, and bone density, resulting in the patient's nutritional state affecting the satisfactory outcome, in patients submitted to a stabilization procedure of the lumbar spine, it being important to identify and correct metabolic values early, using supporting measures to achieve optimum fusion results, 24 since it increases the possibility of developing a thoracic deformity in kyphosis.…”

Objective: To integrate patients with lumbar instability in a multisensor platform in the process of assessment and diagnosis, assigning quantitative parameters for the sagittal balance (SB) and muscle function. Methods: Experimental study involving adult patients diagnosed with diseases that cause alterations in the SB, that were or were not submitted to surgery with posterior instrumentation and fusion. Each patient underwent anthropometric measurements in body composition scale; a kinesiological analysis using a multisensor platform consisting of depth camera to static/dynamic analysis for the quantitative measurement of SB, and surface electromyography to capture the level of abdominal and lumbar muscles activation and through flexion and extension. Results: Seven adult patients: five females (62.5%)and two men (37.5%) with a mean age 48 years. Images with depth cameras resulted in a SB of from -6.4 to +5.3cm (average -5.7cm). In individuals with positive sagittal balance the percentage of activation (PA) of the abdominal muscles was 58.5% and the lower back lumbar was 75.25%; patients with negative SB integrated the PA of the abdominal muscles of 70.25% and lumbar of 65%; the patient with neutral SB exhibited activation of the abdominal muscles of 87.75% and lumbar muscles of 78.25%. Conclusions: We observed a trend towards positive SB in patients with overweight and obesity by BMI, as well as increased activation of the abdominal muscles. The multi sensor platform is a useful tool for the diagnosis and prognosis of diseases involving sagittal imbalance.Keywords: Joint instability; Lumbosacral region; Postural balance; Electromyography. RESUMO Objetivo: Integrar os pacientes com instabilidade lombar em uma plataforma multissensor no processo de avaliação e diagnóstico, atribuindo parâmetros quantitativos para o equilíbrio sagital (ES) e função muscular. Métodos: Estudo experimental com pacientes adultos diagnosticados com doenças que causam alterações no ES, submetidos ou não à cirurgia com instrumentação RESUMENObjetivo: Integrar a pacientes con inestabilidad lumbar a una plataforma multisensor en su proceso de evaluación y diagnóstico, dando parámetros cuantitativos para el balance sagital (BS) y la función muscular. Métodos: Estudio de tipo experimental con pacientes adultos diagnosticados con patologías que causan alteraciones en el BS, unos no operados, y otros operados con instrumentación y fusión posteriores. Cada paciente fue sometido a mediciones antropométricas en báscula de composición corporal; un análisis kinesiólogo utilizando una plataforma multisensor constituida por cámara de profundidad para el análisis estático/dinámico para la medición cuantitativa del BS, y un electromiógrafo de superficie captó el grado de activación muscular en región abdominal y lumbar, mediante movimientos de flexión y extensión. Resultados: Siete pacientes adultos: cinco mujeres (62.5%), dos hombres (37.5%); media de edad de 48 años. Las imágenes con cámaras de profundidad resultaron en un BS de -6.4 a+5.3...
