Test Analysis

The current study aimed to determine the effects of neuromuscular electrical stimulation (NMES) on equine rectus abdominis using surface electromyography (sEMG) and ultrasonographic muscle thickness evaluation. Five horses were trained with NMES for 12 weeks; muscle thickness and sEMG evaluations were obtained before and after the training period. Three different tests were carried out for sEMG evaluations: Test A tried to elicit a voluntary maximal isometric contraction (VMIC); Test B used NMES to elicit a muscular contraction; and Test C used 1 ms repetitive electrical impulses to elicit a series of M-waves. Muscle strength was evaluated from the root mean square (RMS; Tests A and B) and peak to peak (PP; Test C) values obtained from the sEMG data. Measures related to amplitude (RMSa; RMSm; RMSa; PP) were normalised with their pre-training values for every muscle prior to statistical analysis, leading to values as a proportion of the initial value. The evaluation of muscle fatigue was performed using a Fourier test analysis of the frequency range, obtaining the median frequency (MF) for all tests. Muscle thickness (MT) was measured by ultrasound of left and right sides of the rectus abdominis. Data were analysed using non parametric test of Wilcoxon (Test A RMSa; Test A RMSm; Test B RMSa; Test B RMSm; Test C PP; MT; P<0.05) and t-test (Test A MF; Test B MF; Test C MF; P<0.05). Statistical differences were observed between baseline and trained horses. Muscle force increase following NMES training in Test B (RMSa 2.50±0.69; RMSm 2.59±0.76) and Test C (PP 5.20±1.76). Fatigue of the rectus abdominis decreased in Test A (168.33±55.19 vs 232.63±44.15 Hz) and Test C MF (187.93±20.76 vs 236.98±52.39 Hz), but not in Test B (363.98±45.48 vs 327.95±50.84 Hz). The difference in muscle thickness between the two groups was not significant (10.96±0.64; 11.78±0.79 mm). The results suggest that NMES training could be used as an effective method to increase muscle force and fatigue resistance of the rectus abdominis muscle in the horse.

Abstract Background Ileostomy creation is an excellent approach to prevent leakage in patients undergoing low anterior resection for the treatment of rectal cancer. However, the two major complications of ileostomy are outlet obstruction and high-output stoma, and these complications remain unavoidable postoperative problems of ileostomy. Methods Risk factors associated with outlet obstruction and high-output stoma were retrospectively analyzed. The study included 83 patients with rectal cancer who underwent surgery. Of these patients, 34 underwent ileostomy creation. Results We found that outlet obstruction and high-output stoma were highly related (p = 0.03). Additionally, a thick rectus abdominis muscle and advanced T stage were the common risk factors of outlet obstruction (p = 0.0005 and p = 0.01, respectively) and high-output stoma (p = 0.04 and p = 0.03, respectively). Conclusions Our findings suggest that rectus abdominis muscle thickness and advanced T stage are predictive markers of outlet obstruction and high-output stoma.

Anterior Rectal Resection

Background: The outlet obstruction (OO) rate is 5.4-18.4% after defunctioning ileostomy (DI) following rectal cancer resection to reduce the incidence and severity of anastomotic leakage; OO affects a patient’s quality of life and prolongs hospitalization. Patients and Methods: A retrospective analysis was performed of patients who underwent anterior rectal resection and DI for rectal cancer. Results: Among 100 patients undergoing anterior rectal resection with DI for rectal cancer, 28 (28%) developed OO. Anastomotic leakage and a rectus abdominis muscle thickness ≥10 mm on preoperative computed tomography were significantly associated with the risk of OO in univariate analysis. Multivariate analysis also demonstrated that anastomotic leakage (odds ratio=4.320, 95% confidence interval=1.280-14.60, p=0.019) and rectus abdominis muscle thickness ≥10 mm (odds ratio=3.710, 95% confidence intervaI=1.280-10.70, p=0.016) were significantly risk factors for OO. Conclusion: When OO is observed, an anastomotic leakage should be suspected, especially if there is a high rectus abdominis muscle thickness.

Aim: The purpose of the present study was to establish which type of exercise is optimal for Rectus Abdominis (RA) muscle, by measuring thickness and length changes using the extended field of view ultrasonography (EFOV US) during different conditions. The second purpose was to estimate the reliability of EFOV US as a muscle morphology assessment tool.Material and methods: Segmental muscle thickness and length of 11 young healthy adults was assessed during 1) rest and isometric 2) trunk lifting, 3) leg lifting and 4) combined trunk and leg lifting exercises with the use of EFOV US.Results: RA muscle thickness was significantly greater during exercises compared to rest (p<0.05). It was also observed that proximal and proximal-middle segments showed significantly less thickness and length compared to distal-middle and distal segments (p<0.05). Even though no differences in thickness were observed between the exercises, leg lifting and combined trunk and leg lifting exercises affected more the distal segment of RA muscle (p<0.05). Moreover, no significant differences in length between exercises was found (p>0.05). Further, EFOV US displayed excellent reliability as the ICC values ranged from 0.82 to 0.97.Conclusions: According to our observations it seems that exercises that induce lifting of the legs might be more effective for the distal parts of RA muscle. EFOV appears to be a reliable diagnostic tool for measuring RA muscle thickness during rest and contracting states.
