UNASSIGNED: Moderate-to-severe intensity pain is reported on the first day following lower abdominal surgery. No study has compared transversus abdominis plane (TAP) block with retrolaminar block (RLB) in laparoscopic inguinal hernia surgery for postoperative pain relief.
UNASSIGNED: In this prospective, randomized trial, 42 male patients of American Society of Anesthesiologists (ASA) physical status I and II, aged 18-65 years, and having a BMI <40 kg/m2 received TAP or RLB following laparoscopic inguinal hernia surgery. A standard general anesthetic technique was performed. Patients were randomized into two groups: single-shot TAP block (group I) (n = 21) or the RLB (group II) (n = 21) with bilateral 20 ml of 0.375% ropivacaine. Postoperatively, IV paracetamol 1 g was administered as rescue analgesia. Postoperative cumulative Visual Analogue Scale (VAS) score 24 hours after surgery was considered as the primary outcome.
UNASSIGNED: Postoperative cumulative VAS score at rest at 24 h, represented as mean ± S.D (95% CI), in the TAP block group was 3.54 ± 3.04 (2.16-4.93) and in the RLB group was 6.09 ± 4.83 (3.89-8.29). P value was 0.112 and VAS on movement was 7.95 ± 3.41 (6.39-9.50 [2.5-15.0]) in TAP block group, whereas P value was 0.110 and VAS on movement was 10.83 ± 5.51 (8.32-13.34) in the RLB group.
UNASSIGNED: Similar postoperative cumulative pain score on movement at 24 h was present in patients receiving TAP block or RLB. However, VAS score at rest and on movement was reduced in patients receiving TAP block at 18 and 24 h postoperatively.

Background: Patellofemoral osteoarthritis (PF OA) is exceptionally predominant and limiting. However, little is known about the risk factors that contribute to its onset and progression. Purpose: The aim of this study was to decide if women with PF OA descend stairs using different muscular activation strategies compared to similarly aged healthy controls. Methods: Thirty-one women with isolated PF OA and 11 similarly aged healthy women took part in this study. The activation onset and duration of PF OA in vastus medialis oblique (VMO), vastus lateralis (VL), gluteus medius (GM), transversus abdominis (TrA), and multifidus muscles were evaluated during the stair descent task using surface electromyography (EMG). Results: There was a non-significant difference between women with PF OA and healthy controls regarding all tested variables, except for the GM activation onset that was significantly delayed in women with PF OA, with the p-value of 0.011. Conclusion: The causes of PF OA differ and might not always be due to a lack of quadriceps strength or VMO activation deficiency, and prospective longitudinal studies are required to confirm this assumption.

UNASSIGNED: To determine feasibility of a randomized controlled trial (RCT) comparing postpartum rectus abdominis training with transversus abdominis training in reducing the inter-recti distance in patients with diastasis of the rectus abdominis muscles (DRAM).
UNASSIGNED: A pilot, randomized controlled trial with longitudinal assessment following vaginal delivery at 6 and 12 weeks postpartum was completed. Forty-four women with DRAM (inter-recti distance of ≥ 30mm as measured by digital calipers) were recruited from a regional public hospital in Australia. The standard treatment group (n = 21) was provided with a 5-second transversus abdominis activation exercise in crook lying. The experimental group (n = 23) was provided with a 1-second rectus abdominis crunch exercise. Dosage was between 1-10 repetitions at baseline and between 1-20 at 6 weeks, twice a day, at least 5 days per week, prescribed depending on individual participant ability. The primary outcome measure was inter-recti distance. Feasibility measures were recruitment rate, loss to follow-up, adverse events, and exercise adherence.
UNASSIGNED: The rectus abdominis group achieved greater reduction of the inter-recti distance at 6 weeks (at and below the umbilicus) and 12 weeks (above, below, and at the umbilicus). Recruitment rate was acceptable (45%) and there were no adverse events, but loss to follow-up was high due to COVID-19 impacts and participants did not return exercise adherence diaries.
UNASSIGNED: Prescription of rectus abdominis exercise during the early postpartum period following vaginal delivery resulted in a greater reduction of the inter-recti distance at 6 and 12 weeks when compared with transversus abdominis exercise. This pilot trial was impacted by high loss to follow up due to COVID-19 restrictions, but feasibility was otherwise acceptable. The findings of the study will inform future fully powered trials comparing these two exercise types in postpartum women with DRAM.
UNASSIGNED: déterminer la faisabilité d’une étude randomisée et contrôlée pour comparer l’entraînement des grands droits à l’entraînement des muscles transverses afin de réduire la distance intermusculaire chez les patientes ayant une diastase des grands droits (DGD).
UNASSIGNED: étude pilote randomisée et contrôlée comportant une évaluation longitudinale six et 12 semaines après un accouchement vaginal. Au total, 44 femmes ayant une DGD (distance intermusculaire d’au moins 30 mm, mesurée à l’aide d’une règle à coulisse numérique) ont été recrutées dans un hôpital régional public de l’Australie. Le groupe sous traitement standard (n = 21) a reçu un exercice d’activation des muscles transverses de cinq secondes en position allongée sur le dos, les genoux pliés. Le groupe expérimental (n = 23) a reçu un exercice de demi-redressement assis des grands droits d’une seconde. La posologie de une à dix répétitions pour commencer et de une à 20 répétitions deux fois par jour la sixième semaine, au moins cinq jours par semaine, dépendait de la capacité de chaque participante. La mesure d’issue primaire était la distance entre les muscles. Les mesures de faisabilité étaient le taux de recrutement, la perte au suivi, les événements indésirables et l’adhésion aux exercices.
UNASSIGNED: le groupe d’exercices des grands droits a réduit davantage la distance entre les muscles au bout de six semaines (à l’ombilic et sous l’ombilic) et de 12 semaines (au-dessus et au-dessous de l’ombilic et à l’ombilic). Le taux de recrutement était acceptable (45 %) et il n’y avait pas d’événements indésirables, mais la perte au suivi était élevée à cause des conséquences de la COVID-19, et les participantes n’ont pas remis leur journal d’adhésion aux exercices.
UNASSIGNED: la prescription d’exercices des grands droits au début de la période postnatale après un accouchement vaginal favorisait une plus grande réduction de la distance entre les grands droits au bout de six et 12 semaines que les exercices des muscles transverses. L’étude pilote a été touchée par une forte perte au suivi à cause des restrictions liées à la COVID-19, mais la faisabilité était autrement acceptable. Les résultats de l’étude éclaireront de futures études comportant un plein échantillonnage pour comparer deux types d’exercices postnatals chez des femmes présentant une diastase des grands droits.

The transversus abdominis (TrA) is a core muscle that contributes to functional mobility and lumbar stability. This study aimed to compare the changes in TrA thickness during different Pilates exercises, and to identify the exercise that elicited the greatest TrA activation. Forty-four healthy women were divided into two groups: young (25-35 years old) and middle-aged (36-55 years old). TrA thickness was assessed by ultrasound while the participants performed five Pilates exercises: basic position, hundred, hip roll, side plank, and dead bug. A repeated measures analysis of variance revealed that the dead bug exercise induced a significantly higher increase in TrA thickness (relative to rest) than the other exercises (p < 0.05). The young group also showed a significantly higher overall TrA thickness than the middle-aged group (p < 0.05). The findings suggest that the dead bug exercise is the most effective for enhancing TrA activation among the Pilates exercises tested. The basic position and the hundred exercises can be used as warm-up exercises before performing more challenging exercises such as the hip roll, the side plank, and the dead bug. The sequence of exercises can be similar for both young and middle-aged women.

The Transversus Abdominis Plane (TAP) block is a regional abdominal wall block that has been effectively used as an adjunct to alleviate postoperative pain. The ultrasound-guided TAP (USTAP) administered by anesthesiologists is the gold standard and has been effective for surgeries involving abdominal wall incisions. Recently, the TAP block has been administered by surgeons with the help of direct visualization during minimally invasive surgery. The surgeon-administered or laparoscopic-guided TAP block has been compared to the USTAP with no discernible difference in patient outcomes. Also, directly visualizing the injection in the surgeon-administered block can offset complications such as visceral injury and block failure (injectate in the wrong plane). This review explores the literature\'s surgeon-administered TAP blocks for minimally invasive surgery in the literature. In addition, the prerequisite anatomy of the anterolateral abdominal wall, various approaches, and other factors that influence the efficacy of the block are described to increase awareness of this analgesic tool among surgeons and achieve better postoperative pain management.

Lumbar plexus block is often used as analgesia for adult hip surgery, but it is rarely used in pediatric patients. This study aimed to compare the efficacy and feasibility of ultrasound-guided lumbar plexus block versus transversus abdominis plane block for postoperative analgesia in children with hip dislocation. Eighty children undergoing unilateral hip dislocation surgeries at our hospital from October 2019 to February 2021 were randomized to the lumbar plexus block group (group L) and transversus abdominis plane block group (group T). Compared with group L, the regional block time in group T was lower (8.0 ± 2.5 vs 11.5 ± 2.3 min, P < 0.05), and the ultrasound image definition was better (P < 0.05). There were no significant differences in mean blood pressure and heart rate within 24 h (all P > 0.05). Children\'s Hospital of Eastern Ontario Pain Scale scores were lower in group L than in group T at 18-24 h only (all P < 0.05). The satisfying analgesia rate in group L was higher than in group T (87.5 vs 65%, P < 0.05). No regional block-related complications were found in both groups. Ultrasound-guided lumbar plexus block showed a longer postoperative analgesic effect in children with hip dislocation compared with transversus abdominis plane block.

UNASSIGNED: The transversus abdominis (TrA) and multifidus (MF) muscles are essential in preventing chronic low back pain (CLBP) recurrence by maintaining segmental stabilization and stiffness. Sling exercise is a high-level core stability training to effectively improve the activities of the TrA and MF muscles. However, the neural mechanism for sling exercise-induced neural plasticity change in the primary motor cortex (M1) remains unclear. This study aimed to investigate the role of sling exercise in the reorganization of the motor cortical representation of the TrA and MF muscles.
UNASSIGNED: Twenty patients with CLBP and 10 healthy individuals were recruited. For map volume, area, the center of gravity (CoG) location (medial-lateral location and anterior-posterior location), and latency, two-way ANOVA was performed to compare the effects of groups (the CLBP-pre, CLBP-post, and healthy groups) and the two muscles (the TrA and MF muscles). The Visual Analog Scale (VAS), the Oswestry Disability Index (ODI), and postural balance stability were assessed at baseline and at the end of 2 weeks of sling exercise. Linear correlations between VAS or ODI and CoG locations were assessed by Pearson\'s correlation test.
UNASSIGNED: 2 weeks of sling exercise induced both the anterior-medial (P < 0.001) and anterior-posterior (P = 0.025) shifts of the MF muscle representation at the left motor cortex in patients with CLBP. Anterior-medial (P = 0.009) shift of the TrA muscle representation at the right motor cortex was observed in patients with CLBP. The motor cortical representation of the two muscles in patients with CLBP after sling exercise (TrA: 2.88 ± 0.27 cm lateral and 1.53 ± 0.47 cm anterior of vertex; MF: 3.02 ± 0.48 cm lateral and 1.62 ± 0.40 cm anterior of vertex) closely resembled that observed in healthy individuals (TrA: 2.83 ± 0.48 cm lateral and 2.00 ± 0.43 cm anterior of vertex; MF: 2.94 ± 0.43 cm lateral and 1.77 ± 0.48 cm anterior of vertex). The VAS and the ODI were reduced following the sling exercise (VAS: P < 0.001; ODI: P < 0.001).
UNASSIGNED: This study provides evidence that sling training can drive plasticity changes in the motor system, which corresponds with the reduction in pain and disability levels in patients with CLBP. This study was registered in the Chinese Clinical Trial Registry (Clinical Trial Registration Number: ChiCTR2100045904, http://www.chictr.org.cn/showproj.aspx?proj=125819).

Pelvic floor muscle training is recommended as first line treatment for urinary incontinence in women based on three proposed theorized mechanisms: \'Enhanced Pelvic Floor Muscle Strength,\' \'Maximized Awareness of Timing,\' and \'Strengthened Core Muscles\'. The purpose of this scoping review was to systematically map evidence for and against theorized mechanisms through which pelvic floor muscle training interventions work to reduce urinary incontinence in women.
The scoping review is based upon a comprehensive search of relevant literature published from 1990 to 2020 in PubMed, CINAHL, PsycINFO, ClinialTrials.gov, reference lists from review articles, and hand searches of articles by known researchers in the field. We included English-language, peer-reviewed articles on pelvic floor muscle training as an intervention for adult women if they provided empirical evidence to testing the theorized intervention mechanisms. Two independent reviewers screened articles for inclusion and extracted data to describe details of each study (author, year, country, design, sampling), measures of pelvic floor muscle strength and urinary incontinence, statistical analysis of linkage between changes in the measures, and pelvic floor muscle training regimens. Data were summarized to facilitate the integration of diverse evidence to draw conclusions on supporting or refuting the three proposed theorized mechanisms for managing urinary incontinence in women.
Of the 278 articles identified with the search, 13 (4.7%) met inclusion criteria. There was weak to no evidence for the mechanism of enhanced pelvic floor muscle strength, equivocal support for maximized awareness of timing, and no evidence for strengthened core muscles.
This review revealed extremely limited data supporting the proposed theorized mechanisms underlying pelvic floor muscle training programs to manage urinary incontinence in women. Such evidence is needed to help women and clinicians understand how, why and when a woman benefits from pelvic floor muscle training. Future studies should specifically state and report statistical analysis that relates the theorized mechanisms to the training outcomes observed.

UNASSIGNED: The expiratory muscles are an indispensable component of respiratory function in critically ill patients, yet is often overlooked. We evaluated the association of abdominal expiratory muscles thickness pattern with weaning.
UNASSIGNED: This was a single-center, prospective observational study done on 81 adult mechanically ventilated patients who underwent the weaning process.
UNASSIGNED: Sixteen patients had simple weaning and 65 patients had either difficult or prolonged weaning. The mean and standard deviation (SD) of the thickness of expiratory abdominal muscles-rectus abdominis (RA), internal oblique (IO), external oblique (EO), and transversus abdominis (TA) were significantly more in patients with simple weaning than those with difficult or prolonged weaning. The receiver operating curve (ROC) of expiratory muscles showed RA, IO, EO, TA cut-offs 0.638, 0.492, 0.315, and 0.253 cm, respectively, to predict simple weaning. The pattern of expiratory muscle thickness RA > IO > EO > TA was maintained in both simple and difficult/prolonged weaning groups (p = 0.362). The ROC of diaphragmatic excursion (DE) for predicting simple weaning had cut-off 1.79 cm. The lung ultrasound score (LUS) was 5.75 ± 3.32 in the simple weaning group, compared to 9.71 ± 5.18 in the difficult/prolonged weaning group (p = 0.005).
UNASSIGNED: Abdominal expiratory muscles were significantly thicker in patients with simple weaning compared to those with difficult or prolonged weaning. The pattern of expiratory muscle thickness followed the pattern of RA > IO > EO > TA in both simple weaning and difficult or prolonged weaning groups. DE >1.79 cm predicted simple weaning and LUS was significantly lesser in patients with simple weaning (CTRI/2020/11/028895).

UNASSIGNED: The aim of this study was determination of the effect of the transversus abdominis plane block (TAP block) with ropivacaine 0.5% in relieving postoperative pain after laparoscopic gynecologic surgery.
UNASSIGNED: The population of the double-blinded clinical trial study included 200 women candidates for elective laparoscopic gynecologic surgery who referred to Al-Zahra and Beheshti hospitals in Isfahan during 2016-2018. In the TAP block group in addition to standard general anesthesia, an anesthetic drug Ropivacaine (Naropin, 0.5%) was injected at a dose of 0.5 mg/kg between transverse abdominal muscle and internal oblique muscle facia. And in control group just received standard general anesthesia. Hence, the severity of pain and nausea and vomiting is recorded at the time of recovery, at 30 min, 2, 4, 6, 12, and 48 h after the surgery.
UNASSIGNED: The results of this study showed that in all periods of time (30 min, 2, 4, 6, 12, 24, 36, and 48 h after the surgery), mean pain score in TAP block group was lower than control group (P < 0.001). Hence that, in the 48 h after the surgery, the pain score in the TAP block group with a mean of 0.46 ± 0.50 was significantly lower than the control group with a mean of 1.06 ± 0.68 (P < 0.001). Nausea and vomiting between the two groups were no significant differences. There was no decrease in narcotic use or length of stay among those who received the TAP block.
UNASSIGNED: TAP block with ropivacaine 0.5% had a significant role in reducing postoperative pain of laparoscopic surgery.
