Revista da Associação Médica Brasileira, 64(12), 1134-1138. https://doi.org/10.1590/1806-9282.64.12.11340104-4230http://hdl.handle.net/11268/7878The present quasi-experimental study aimed to assess the transversus abdominis (TrA), internal oblique (IO) and external oblique (EO) thickness in healthy subjects with the proprioceptive StabilizerTM training in abdominal wall muscles. A sample of 41 healthy participants (age: 31.9 ± 4.5 y; height: 1.7 ± 0.1 m; weight: 68.3 ± 13.1 kg; body mass index, BMI: 22.9 ± 2.7 kg/m2 ) were recruited to participate in this study. Ultrasound images of the EO, IO, TrA, rectus anterior (RA) and interrecti distance (IRD) were measured and analyzed by the ImageJ software. Measurements were made at rest and during the abdominal drawing-maneuver (ADIM) developed by the patients with the StabilizerTM located in the low back holding 40 mmHg for 10 seconds with a visual stimulus provided by a circular pressure marker. Ultrasound measurements for the abdominal wall muscles showed statistically significant differences (P < .05) for a thickness decrease of the EO, IO and a thickness increase of TrA. A proprioceptive StabilizerTM training produced a thickness increase in TrA muscle and a thickness decrease in EO and IO muscles in healthy subjects. These findings suggest that a proprioceptive StabilizerTM training could be useful in individuals with low back pain and lumbopelvic pain.engjournal article10.1590/1806-9282.64.12.1134open accessFisiología del ejercicioEntrenamiento deportivoFisiología humanaAtleta
