RESUMO

BACKGROUND: Abdominal Hypopressive Training (AHT) provides postural improvement, and enhances deep trunk muscle activation. However, until recently, there was a lack of scientific literature supporting these statements. The major purpose of this study was to investigate the effect of AHT on posture control and deep trunk muscle function. METHODS: 125 female participants aged 18-60 were randomly allocated to the Experimental Group (EG), consisting of two sessions of 30 min per week for 8 weeks of AHT, or the Control Group (CG), who did not receive any treatment. Postural control was measured with a stabilometric platform to assess the static balance and the activation of deep trunk muscles (specifically the Transverse Abdominal muscle (TrA)), which was measured by real-time ultrasound imaging. RESULTS: The groups were homogeneous at baseline. Statistical differences were identified between both groups after intervention in the Surface of the Center of Pressure (CoP) Open-Eyes (S-OE) (p = 0.001, Cohen's d = 0.60) and the Velocity of CoP under both conditions; Open-Eyes (V-OE) (p = 0.001, Cohen´s d = 0.63) and Close-Eyes (V-CE) (p = 0.016, Cohen´s d = 0.016), with the EG achieving substantial improvements. Likewise, there were statistically significant differences between measurements over time for the EG on S-OE (p < 0.001, Cohen´s d = 0.99); V-OE (p = 0.038, Cohen´s d = 0.27); V-CE (p = 0.006, Cohen´s d = 0.39), anteroposterior movements of CoP with Open-Eyes (RMSY-OE) (p = 0.038, Cohen´s d = 0.60) and activity of TrA under contraction conditions (p < 0.001, Cohen´s d = 0.53). CONCLUSIONS: The application of eight weeks of AHT leads to positive outcomes in posture control, as well as an improvement in the deep trunk muscle contraction in the female population.

RESUMO

Abdominal muscles may be both morphologically and functionally affected by pregnancy. Dysfunction of the muscles can lead to persistent postpartum low back pain. The recovery process of the abdominal muscles following childbirth is not well understood. This study aimed to demonstrate the changes in the thickness and contractile function of abdominal muscles during the first six months postpartum. Nine perinatal and 15 nulliparous females participated. The thicknesses and contraction/relaxation thickness ratios of the rectus abdominis (RA), external abdominal oblique (EO), internal abdominal oblique (IO), and transverse abdominis (TrA) were measured using ultrasound images from 36-39 weeks' gestation until six months postpartum. The RA, IO, and TrA muscles were thinner in perinatal females than controls at 36-39 weeks of gestation (4.8 vs. 9.47 mm (RA), 5.45 vs. 7.73 mm (IO), 2.56 vs. 3.38 mm (TrA), respectively). The thinner IO muscle persisted for six months after delivery. The decreased TrA thickness ratio persisted until four months post-delivery. Abdominal muscle thickness and contractile function decreased in the postpartum period. Therefore, abdominal muscle exercises might help prevent postpartum symptoms; however, because deterioration of muscle function is significant in the first four months, careful attention should be paid to exercise intensity. The study limitation was a relatively small sample size, thus future studies should involve more participants.

RESUMO

RATIONALE: An abdominal pseudohernia is a protrusion of the abdominal wall that there is no actual muscular disruption. This report presents a case in which abdominal muscle activities were accurately and quantitatively measured using ultrasonography (US) and surface electromyography in a patient with abdominal pseudohernia. PATIENT CONCERNS: A 62-year-old man presented with a marked protrusion on the left abdomen with increasing abdominal pressure. DIAGNOSES: First, the thickness of the abdominal muscle was measured with US while the patient constantly blew the positive expiratory pressure device. When the force was applied to the abdomen, the mean thickness of the muscle layer on the lesion site was found to be thinner. Second, the activities of the abdominal muscles were measured using surface electromyography by attaching electrodes to 8 channels at the same time. When the same pressure was applied on both sides of the abdomen, more recruitment occurred to compensate for muscle weakness at the lesion site. Through the previous 2 tests, the decrease in muscle activity in the lesion area could be quantitatively evaluated. Third, the denervation of the muscle was confirmed using US-guided needle electromyography. INTERVENTIONS: The patient in this case was wearing an abdominal binder. In addition, he had been training his abdominal muscles through McGill exercise and breathing exercises such as with a positive expiratory pressure device. OUTCOMES: The patient was able to understand his symptoms. A follow-up test will be performed to see if there is any improvement. LESSONS: By using these outstanding assessment methods, proper diagnosis and rehabilitation treatment strategies can be developed.

RESUMO

The practice of regional anesthesia is in a state of progressive evolution, mainly due to the advent of ultrasound as an anesthesiologist's instrument. Alternative techniques for postoperative analgesia of abdominal surgeries, such as transversus abdominis plane block, oblique subcostal transversus abdominis plane block, rectus abdominis muscle sheath block, ilioinguinal and iliohypogastric nerve block, and quadratus lumborum plane block, have proven useful, with good analgesic efficacy, especially when neuroaxial techniques (spinal anesthesia or epidural anesthesia) are not possible. This review discusses such blockades in detail, including the anatomical principles, indications, techniques, and potential complications.

RESUMO

Background: Acute postoperative pain after myomectomy can impair patient function. Like all other postoperative pain, it is a challenge requiring solution, particularly in developing countries. Ultrasound-guided transversus abdominis plane (TAP) block and wound infiltration (WI) are both known to be effective in managing postoperative pain. It is not certain if transversus abdominis plain block would be superior to wound infiltration. Aims: It was hypothesized that the TAP block has similar analgesic effectiveness to wound infiltration. Subjects and Methods: This study was a randomized controlled trial involving, seventy-four (74) patients scheduled for myomectomy at the University of Benin Teaching Hospital Benin City, Nigeria under the subarachnoid block, which were randomized into TAP and WI group preoperatively. The ultrasound-guided bilateral TAP block group and wound infiltration group (subfascial and subcutaneous infiltration) each used 40 mL of 0.25% of plain bupivacaine to achieve postoperative analgesia. The time to first analgesic request, numerical pain rating scale (NRS) score at rest, and movement were assessed. Data were analyzed using SPSS version 16 (Chicago Il, USA). Results: The time to first analgesic request was significantly delayed in the TAP block group compared to the wound infiltration group [240 (131, 375) min vs 170 (128, 187) minutes. P = 0.006]. The proportions of patients with NRS score ≤3 at the time of first analgesic requests were significantly more in the TAP block group (P < 0.001). The analgesic consumed by the TAP block group was significantly low compared to the WI group. There were no incidences of complications due to TAP block or wound infiltration. Conclusion: TAP block provided a longer duration of analgesia and a clinically superior quality of analgesia to wound infiltration.

RESUMO

BACKGROUND: Transversus abdominis plane (TAP) blocks provide postoperative pain relief after various abdominal surgeries. Recently, erector spinae plane (ESP) block has obtained vast attention due to its simplicity and usage in truncal procedures. OBJECTIVES: This study aims to compare the ultrasound-guided bilateral ESP block versus bilateral TAP block on postoperative analgesia after open total abdominal hysterectomy. STUDY DESIGN: A prospective, double-blinded, randomized, controlled, clinical trial. SETTING: Zagazig University Hospitals. METHODS: After ending of surgical procedure and before reversing of the muscle relaxant, 48 women were randomly allocated into 2 equal groups: erector spinae (ES) group received bilateral ultrasound-guided ESP block with 20 mL of bupivacaine 0.375% plus 5 ug/mL adrenaline (1:200000) in each side at the level of T9, and transversus abdominis (TA) group received bilateral ultrasound-guided TAP block with the same volume of bupivacaine plus adrenaline. RESULTS: Visual Analog Scale scores at 30 minutes, 2, 4, 6, 8, 12, 16, 20, and 24 hours were statistically significantly lower in the ES group compared with the TA group. The time for requirement of first morphine was highly statistically significantly prolonged in the ES group (14.81 ± 3.52 hours) compared with the TA group (10.58 ± 2.35 hours). The total amount of morphine consumption in 24 hours postoperatively was statistically significantly decreased in the ES group; P = 0.01. Incidence of postoperative nausea and vomiting was higher but statistically insignificant in the TA group than the ES group. There were statistically significant numbers of unsatisfied patients (4) in the TA group compared with the ES group (no patient). LIMITATIONS: Sensorial evaluation of patients was not performed because both blocks had been done under general anesthesia but did not affect outcome. Therefore we recommend further studies comparing between both blocks. CONCLUSIONS: Bilateral ultrasound-guided ESP block provides more potent and longer postoperative analgesia with less morphine consumption than TAP block after open total abdominal hysterectomy. KEY WORDS: Abdominal hysterectomy, transversus abdominis plane block, erector spinae plane block, postoperative analgesia.

RESUMO

BACKGROUND: No preoperative risk assessment tool is available to predict postoperative bulge formation after abdomen-based breast reconstruction. The authors evaluated the association between clinical variables and morphometric measurements on preoperative computed tomographic (CT) angiography and postoperative abdominal wall morbidity. METHODS: The authors evaluated all cases of postoperative bulge/hernia and normal controls in patients who underwent preoperative CT angiography and abdomen-based microsurgical breast reconstruction between July 2009 and January 2018. CT-based abdominal wall profiles, including abdominal wall protrusion, abdominopelvic cavity cross-sectional area (CSA), and abdominopelvic cavity-to-total body CSA ratio, were obtained and analyzed. A novel risk stratification scoring system to stratify the risk of bulge/hernia was developed. RESULTS: Among 463 patients who underwent abdomen-based breast reconstruction, 23 were diagnosed as having a bulge/hernia. Age (OR 2.912; 95% CI 1.157-7.333), lateral row perforator (OR 5.065; 95% CI 1.834-13.986), and abdominal wall protrusion (OR 3.687; 95% CI 1.494-9.100) were significant risk factors associated with postoperative bulge/hernia in the multivariate analysis. Using the risk stratification scoring system, the incidence rates of postoperative bulge/hernia were 1.7%, 4.8%, and 19.0% for low-, intermediate-, and high-risk patients, respectively (p<0.001). CONCLUSIONS: Age, lateral row perforator, and abdominal wall protrusion were significantly associated with postoperative bulge/hernia formation after abdomen-based microsurgical breast reconstruction. The authors' risk score based on the three variables may help predict and minimize donor-site morbidity.

RESUMO

BACKGROUND: The goal of our study was to compare results in patients with large midline incisional hernia using modified anterior component separation versus preoperative botulinum toxin and following Rives repair, with a focus on surgical site occurrences, possibility of fascial closure, duration of hospital stay, and hernia recurrence rate. METHODS: From to March 2016 to June 2019, a prospective comparative study was performed in 80 consecutive patients with large midline incisional hernias and hernia transverse diameters between 11 and 17 cm under elective hernia repair at our tertiary center. Two groups were analyzed prospectively: 40 patients with preoperative botulinum toxin administration and following open Rives repair (botulinum toxin group) were compared with 40 patients who underwent open component separation during that period (component separation group). RESULTS: All large midline incisional hernias were classified W3, with mean transverse and longitudinal defect diameters of 14.9 cm (11.8-16.5) and 24 cm (11-28), respectively. Complete fascial closure was possible in all patients in the preoperative botulinum toxin group. No complications occurred during the administration of preoperative botulinum toxin, but surgical site complications were most frequent in the component separation group, especially skin necrosis (12.5%, P = .020). At a median of 19.6 months (range, 11-35) of postoperative follow-up, 2 cases of hernia recurrence (8.9%) were reported, all of them in the component separation group. CONCLUSION: Botulinum toxin allows getting a successful downstaging from surgical repair to Rives technique in patients with large midline incisional hernia, especially with hernia transverse diameters between 11 and 17 cm. These results contribute to minimize disadvantages associated to the anterior component separation.

RESUMO

Intravital microscopy (IVM) is widely used to monitor physiological and pathophysiological processes within the leukocyte recruitment cascade in vivo. The current protocol represents a practical and reproducible method to visualize the leukocyte endothelium interaction leading to leukocyte recruitment in skeletal muscle derived tissue within the intact organism of the mouse. The model is applicable to all fields of research that focus on granulocyte activation and their role in disease. We provide a step by step protocol to guide through the method and to highlight potential pitfalls and technical difficulties. The protocol covers the following aspects: experimental settings and required material, anesthesia of the mouse, dissection of the cremaster muscle as well as tracheal and carotid cannulation, IVM recordings and offline analysis. Data formats like adherent leukocytes, rolling flux (RF) and rolling flux fraction (RFF) are explained in detail and appropriate applications are discussed. Representative results from dystrophin deficient mdx mice are provided in the results section. IVM is a powerful tool to assess leukocyte recruitment in an in vivo setting; however, delineating for example endothelial and leukocyte function may require a combination with ex vivo setups like flow chamber experiments. Furthermore, the genetic background of animals of interest may greatly influence baseline recruitment, requiring individual fine tuning of the protocol provided. Despite its limitations, IVM may serve as a platform to readily translate in vitro findings into a living vertebrate organism.

RESUMO

BACKGROUND: The use of Pilates in various fields of sport sciences and rehabilitation is increasing; however, little is known about the muscle adaptations induced by this training method. HYPOTHESIS: A standardized Pilates training program for beginners (9 months; 2 sessions of 55 minutes per week) will increase the muscle volume and reduce potential side-to-side asymmetries of the quadratus lumborum, iliopsoas, piriformis, and gluteus muscles (gluteus maximus, medius, and minimus). STUDY DESIGN: Controlled laboratory study. LEVEL OF EVIDENCE: Level 3. METHOD: A total of 12 inactive, healthy women (35.7 ± 5.4 years) without previous experience in Pilates were randomly selected to participate in a supervised Pilates program (36 weeks, twice weekly). Muscle volume (cm3) was determined using magnetic resonance imaging at the beginning and end of the intervention program. Side-to-side asymmetry was calculated as [(left - right volume) × 100/right volume]. RESULTS: Small, nonsignificant (P > 0.05) differences in the volume of the quadratus lumborum, iliopsoas, piriformis, and gluteus muscles were observed between pre- and post-Pilates program timepoints. Before and after Pilates, side-to-side asymmetry was less than 6% and nonsignificant in all muscles analyzed. CONCLUSION: Modern Pilates performed twice weekly for 9 months did not elicit substantial changes in the volume and degree of asymmetry of the selected lumbopelvic muscles in inactive women. CLINICAL RELEVANCE: The benefits of Pilates in rehabilitation or training are likely elicited by neuromuscular rather than morphological adaptations. Pilates has no significant impact on muscle volume and does not alter side-to-side ratios in muscle volume (degree of asymmetry) of the lumbopelvic muscles.

RESUMO

OBJECTIVE: There is a lack of consensus on which abdominal or pelvic floor muscle (PFM) exercises to recommend for the treatment of diastasis recti abdominis (DRA). The objective of this study was to investigate the immediate effect of abdominal and PFM exercises on interrecti distance (IRD) in women with DRA who are parous. METHODS: In this cross-sectional study, 38 women who were parous, with a mean age of 36.2 years (SD = 5.2), diagnosed with DRA participated. IRD was assessed with 2-dimensional real-time ultrasonography during rest and during 8 randomly ordered different exercises. A paired t test was used to compare the IRD at rest with the IRD recorded during each exercise as well as the differences between exercises. Means with 95% CI are reported. RESULTS: Head lift and twisted curl-up exercises significantly decreased the IRD both above and below the umbilicus. Above the umbilicus, the mean IRD difference from rest during head lift was 10 mm (95% CI = 7 to 13.2), whereas during twisted curl-up it was 9.4 mm (95% CI = 6.3 to 12.5). Below the umbilicus, the corresponding values were 6.1 mm (95% CI = 3.2 to 8.9) and 3.5 mm (95% CI = 0.5 to 6.4), respectively, but PFM contraction, maximal in-drawing, and PFM contraction + maximal in-drawing increased the IRD (mean difference = -2.8 mm [95% CI = -5.2 to 0.5], -4.7 mm [95% CI = -7.2 to -2.1], and - 5.0 mm [95% CI = -7.9 to -2.1], respectively). CONCLUSIONS: Head lift and twisted curl-up exercises decreased the IRD both above and below the umbilicus, whereas maximal in-drawing and PFM contraction exercises only increased the IRD below the umbilicus. A randomized controlled trial is needed to investigate whether head lift and twisted curl-up exercises are effective in permanently narrowing the IRD. IMPACT: To date there is scant scientific knowledge of which exercises to recommend in the treatment of DRA. In-drawing and PFM contraction leads to an acute increase in IRD, while head lift and twisted curl-up leads to an acute decrease in IRD in postpartum women. There is a need for high-quality randomized controlled trials to investigate if there is a long-term reduction in IRD by doing these exercises over time. The acute IRD increase and decrease during the different exercises is also present in a sample of women with larger separations.

RESUMO

BACKGROUND: Due to the opposing cardiovascular risk profiles of CAC volume and density, we tested the hypothesis that increased abdominal muscle area (AMA) and density (AMD) were significantly associated with lower coronary arterial calcium (CAC) volume and higher CAC density. METHODS: Using data from 787 participants from the Multi-Ethnic Study of Atherosclerosis, Ancillary Body Composition Study, we analyzed abdominal and chest computed tomography (CT) scans. Abdominal scans were scored for muscle area, muscle density (attenuation) and visceral and subcutaneous fat. Chest scans were scored for CAC volume and Agatston values, which were used to derive CAC density scores. RESULTS: The mean (SD) age and BMI of the participants was 67.8 (9.0) years and 27.9 (4.8) kg/m2, respectively. Forty-one percent were female, 46% were Caucasian, 60% had hypertension, 17% had diabetes, and 46% had dyslipidemia. AMA was positively associated with CAC volume (p < .001) and inversely associated with CAC density (p < .001). Conversely, AMD was inversely associated with CAC volume and positively associated with CAC density in minimally adjusted models (p < .001), but not significant in confounder adjusted models. CONCLUSION: AMA and AMD had differing associations with CAC volume and density, with AMA significantly associated with a higher risk CAC profile (high volume, low density) and AMD not significantly associated with CAC volume or density. Future research needs to account for the unique components of both muscle composition and CAC.

RESUMO

Bridging exercises with abdominal hollowing are often used as a regimen for improving spinal stability. Lately, this type of training has become very popular among elite athletes, creating a need for more demanding exercises. The purpose of this study was to investigate whether the use of additional external resistance is beneficial for abdominal muscle recruitment during bridge exercise. Tissue movement of the transversus abdominis (TrA) and the rectus abdominis (RA) was recorded with the use of two synchronized ultrasonic devices, in 20 healthy college students. From the hook-lying position participants were examined in eight different exercise conditions: a) rest, b) abdominal drawing-in maneuver (ADIM), c) bridge, d) bridge- ADIM, e) bridge with 10KG, f) bridge- ADIM with 10KG, g) bridge with 20KG and h) bridge-ADIM with 20KG. Analysis of variance (ANOVA) showed a statistically significant increase in TrA thickness when performing the bridge exercise combined with ADIM compared to rest mode (p < .05). RA thickness decreased when the ADIM was performed, compared to rest (p < 0.05). No significant difference in TrA and RA thickness when exercising with and without external resistance was observed (p > 0.05). The main outcome of this study was that external loading provided some extra level of difficulty, yet it was not beneficial for abdominal muscle recruitment, when performing a supine bridge exercise.

RESUMO

BACKGROUND: Neuromuscular electrical stimulation (NMES) devices for abdominal muscles are being marketed to the general public to improve physical appearance. Abdominal muscles play an important role in lumbopelvic stability for optimizing performance. We investigated the effects of NMES training of abdominal muscles on muscle size, muscle strength, endurance, and lumbopelvic stability. METHODS: Twenty-three subjects (12 females, 11 males) performed abdominal muscle NMES training for 8 weeks. Before and after NMES training, we measured muscle size (cross-sectional area [CSA] of the rectus abdominals [RA] and lateral abdominal wall [LAW]) by magnetic resonance imaging, muscle strength (trunk flexor and side bridge strength), endurance (trunk flexor and side bridge endurance time), and lumbopelvic stability (one-leg loading test). RESULTS: There were significant increases between pre- and post-NMES training differences in the size (CSA of RA 21.7-25.4%, P<0.001; CSA of LAW 9.00-9.71%, P<0.001), strength (trunk flexor 14.9%, P<0.05; side bridge 33.7-53.6%, P<0.05), and endurance (trunk flexor 29.1%, P<0.05; side bridge 24.6-28.9%, P<0.05) of abdominal muscles and lumbopelvic stability (37.2-37.4%, P<0.05). CONCLUSIONS: NMES training could be applied to increase muscle size and muscle performances of abdominal muscles in sports and fitness fields.

RESUMO

Eosinophilic ascites, owing to serosal involvement, is a very rare manifestation of eosinophilic gastroenteritis in children, especially when it occurs with muscular involvement in the absence of mucosal disease, which may be confirmed by endoscopic ultrasonography. An 11-year-old girl, presenting with massive eosinophilic ascites and colicky abdominal pain with peripheral eosinophilia, raised IgE levels and positive skin prick test, had such investigation which confirmed the presence of muscle layer thickening of both stomach and small bowel. She responded well to steroids and montelukast.

RESUMO

Extracorporeal shockwave lithotripsy (ESWL) is widely used for the treatment of urinary tract calculi; however, the vast majority of the patients does not tolerate the procedure without analgesia and sedation. Pain control in ESWL has been crucial for process success and patient comfort. Systemic drugs, such as non-steroid anti-inflammatory drugs, opioids, alfa-2 agonist and various local and regional anesthesia methods (transversus abdominis plane block, paravertebral block, infiltration) have been applied to control ESWL pain. Quadratus lumborum block (QLB) is performed as one of the regional anesthetic techniques for abdominal surgery. This block provides anesthesia and analgesia on the anterior and lateral wall of the abdomen. In this report, we presented the analgesic efficacy of QLB in 15 patients, which included nine renal and six ureter stones for ESWL. The mean of the VAS scores ranged from 0.20±0.41 to 2.73±1.22, and mean fentanyl consumption was 15.00±15.08 mcg during the procedure. No opioid-related side effects were observed in any of the patients. Full fragmentation was obtained in nine of the 15 patients, and partial fragmentation was obtained in five patients.

RESUMO

BACKGROUND: Avulsion injuries of the pelvis and hip region are typical injuries in adolescent athletes but can be found in adults as well. Typical sites for avulsion injuries include the origin/insertion of tendons and ligaments. Among adolescents, the not yet ossified apophysis is also frequently involved. The pelvis and hip are especially prone to such injuries due to their complex musculotendinous anatomy. Clinical history and physical examination in combination with the recognition of typical imaging findings are essential for correct diagnosis of these mostly acute, but sometimes also chronic injuries. METHODS: This review article describes typical avulsion injuries of the pelvis and hip and illustrates common radiological findings. Taking current literature into account, there is a special focus on the trauma mechanism, clinical examination, typical imaging findings and clinical management. RESULTS AND CONCLUSION: Detailed knowledge of musculotendinous anatomy and typical injury mechanisms allows a correct diagnosis of avulsion injuries often only based on clinical examination and radiographic findings. Further imaging with ultrasound and MRI may be necessary to evaluate tendon retraction in non-osseous avulsion injuries and extent of soft-tissue damage. Knowledge of potential complications of acute/chronic injuries can help to avoid unnecessary examinations or invasive interventions. Conservative management of avulsion injuries usually leads to functionally good results. However, in the case of competitive athletes, relatively wide bone fragment dislocation or marked tendon retraction, operative re-fixation may be considered in order to expedite the rehabilitation process. KEY POINTS: · Avulsion injuries are common injuries at the pelvic region especially in adolescent athletes, due to not yet ossified apophysis.. · Excellent anatomical knowledge is essential for proper diagnostic evaluation and predicting the mechanism of injury.. · Imaging plays a crucial role in diagnosing avulsion injuries starting from X-Ray and using MRI and CT for anatomical details by utilizing multiplanar capabilities..
