SUMMARY The 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 Stabilizer™ 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 Stabilizer™ 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 (Π < .05) for a thickness decrease of the EO, IO and a thickness increase of TrA. A proprioceptive Stabilizer™ 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 Stabilizer™ training could be useful in individuals with low back pain and lumbopelvic pain.

Objectives: Abdominal hypopressive gymnastics (AHG) is a little-researched method designed to train the muscles of the abdominal wall and pelvic floor under low stress. This study’s objective is to compare levels of muscle activation in AHG against prone bridge by surface electromyography (sEMG) of the abdominal wall muscles. Methods: Twenty healthy subjects were enrolled to measure the muscle activity of the rectus abdominis (RA), transversus abdominis/internal oblique (Tra/IO), and external oblique (EO) during three exercises: prone bridge (PB), orthostatic hypopressive (OH), and hypopressive bridge (HB). Root mean square values normalized to the PB (%PB) as a baseline were used to compare the PB against OH and HB. Results: The median PB ratio (%PB) for the Tra/IO showed –10.31% and +59.7% activation during OH and the HB, respectively, whereas the RA showed –77.8% and +19.3% and the EO –39.8% and +9.8%. Significant differences were found for all muscles except the Tra/IO during the OH. Conclusion: This study’s results suggest that hypopressive exercises facilitate the activation of the Tra/IO similar to bridge exercises while simultaneously reducing RA and EO activity. This suggests that hypopressive training is a valid alternative for activating the abdominal muscles, isolating the Tra/IO at low intra-abdominal pressure.

SUMMARY The purpose of this study was to assess and compare with rehabilitative ultrasound imaging (RUSI) the perimuscular connective tissue (PMCT) and interrecti distance (IRD) between elite and amateur basketball players. A sample of 22 healthy basketball players was included and divided into two groups: elite basketball players from Spanish 1st division (n = 11) and amateur basketball players from an entertainment Spanish division (n = 11). Ultrasound images of the external oblique (EO), internal oblique (IO), transversus abdominis (TrAb), rectus anterior (RA) and IRD PMCT were measured and analysed by the ImageJ software. Measurements of abdominal wall muscles PMCT present statistically differences (P < .05) for an increase of perimuscular connective tissue of external oblique (PMCTEO), perimuscular connective tissue of transversus abdominis (PMCTTA) of the left side and an increase of PMCTEO on the right side in favor of the elite group. Rather, the study showed statistically differences (P < .05) for a decrease of perimuscular connective tissue between the internal oblique and transversus abdominis (PMCTIO-TA), and a decrease in PMCT total summation of the left side with elite group in respect to amateur group. This study reported an increase of left PMCTEO, left PMCTTAA, right PMCTEO as well as a decrease of left PMCTIO-TA and in PMCT total summation on the left side.

Objective: To evaluate the effect of therapeutic exercises on pregnancy related low back pain in a tertiary care hospital of Karachi. Material & Methods: This was a quasi-experimental study with non-probability convenience sampling technique. Study was carried out at Liaquat National Hospital Karachi. Patients were divided into two groups (Experimental and Control). Inclusion criteria were age <30 years, 2nd and 3rd trimester, stable medical status and those who gave the informed consent. Exclusion were pregnancy induced hypertension (>140/90mmHg), Cardiac disease, diabetes mellitus, persistent vaginal bleeding, history of miscarriages, decreased foetal movement. Data was collected through assessment Modified Oswestry Low back pain disability questionnaire. SPSS version 23.0 was used to analyze the data. Results: A total of 30 samples were selected for the study. There were 15 respondents in experimental while 15 in control group. Disability levels were found to be significantly decreased after post treatment in experimental group with P-value= 0.002. It was seen that number of patients was increased from 1(6.7%) to 6(40%) in minimal disability group whereas crippled back pain group in pre-treatment group was totally shifted towards minimal or moderate pain 3(20.0%) and no case was seen in post-treatment. Conclusion: Low back pain in pregnancy can disturb daily life routine but exercise therapy and proper counselling will lead stress free life to female in gestation. After post treatment in experimental group showed decrease in pain as compare to control group who were not provided any exercise therapy. Working women in experimental group also showed decrease by crippled back pain to moderate pain after exercise. So in the end researcher suggest that physiotherapy exercises play a vital role in reducing Low Back Pelvic Pain (LBPP) during pregnancy.

Many experts in abdominal wall reconstruction believe that the combination of simultaneous ipsilateral anterior component separation (ACS) and posterior component separation (PCS) is contraindicated. We performed ipsilateral endoscopic ACS and either endoscopic or open PCS-transversus abdominis release (TAR) in 5 fresh cadaver models. The full length of the semilunar line and the lateral abdominal wall remained well reinforced by 2 complete layers, comprising the internal oblique (IO) and TA muscles and their investing fasciae. Myofascial releases occurred 4 cm (median) apart. Additionally, we reviewed computed tomography images at 1 month and 1 year after PCS-TAR in 17 patients (30 PCS-TARs). Lateral displacement of the TA relative to the rectus abdominis (RA) was significant only at the superior mesenteric artery level, where it was <1 cm (median). Muscle mass changed minimally over time. Several studies showed that abdominal wall reconstruction after PCS-TAR results in compensatory muscular hypertrophy of the RA, external oblique (EO), and IO muscles and provides better quality of life and improved core physiology. These changes did not occur when the midline was not restored. Theoretically, endoscopic ACS-EO may be added to PCS-TAR to avoid partially bridged mesh repair in patients in whom complete midline restoration is impossible via PCS-TAR alone. Nevertheless, we advise most surgeons to perform a small-bridged repair instead of risking increased morbidity by attempting a highly complicated procedure.

Background. Chronic low back pain (LBP) leads to long-term physical and psychological problems and may result in acute deterioration of the pain. It is hypothesized that size changes in selected limb and pelvis muscles during contracting movements are different between healthy individuals and LBP patients. Materials and methods. A case-control study including two groups of 30 female participants with and without LBP symptoms was designed. Participants were 20-45 years old (36.7±6.7, healthy subjects; 34.6±6.2 LBP subjects). Ultrasonography was used to estimate the thicknesses of the quadratus lumborum (QL), gluteus medius (GMed), transversus abdominis (TrA) and lumbar multifidus (MF). Thickness changes of the muscles in a submaximal contracting position compared to the rest position were measured. Statistical analysis included an independent t-test to determine the significance of differences, and the Kolmogrov-Smirnov two-sample test to evaluate the normality and reliability. Results. All muscles increased their thickness during contractions. The average increase in LBP subjects was lower than in the healthy subjects. The smaller increase in the muscle thickness of GMed in the LBP group may suggest a weakness because of imbalance in the GMed muscle of LBP patients. Conclusions. 1. Ultrasonography of local and global muscles is an appropriate device for clinical diagnosis of LBP. 2. Strengthening TrA, MF, and GMed muscles for pain prevention is effective in the prevention and treatment of LBP.
