Comparing and contrasting motor unit recruitment and activation for the same muscles for multiple versus single-joint exercise may provide a better understanding of neuromuscular fatigue. The purpose of this study, therefore, is to compare the slope and y-intercept terms for the three superficial quadriceps femoris (vastus lateralis, rectus femoris, and vastus medialis) muscles derived from the log-transformed EMG amplitude-power output relationship between the single-leg knee-extensor ergometry and the single-leg cycle ergometry...

Reproducibility of frequency content from surface electromyography (sEMG) signals has not been assessed and it is unknown if incremental load testing design could affect sEMG in cycling. The goals of this study were to assess the reproducibility of measures from sEMG frequency content between sessions and to compare these frequency components between a ramp and a step incremental cycling test. Eighteen cyclists performed four incremental load cycling tests to exhaustion. Two tests were performed using a step increment (load started at 100 W for 3 min followed by increments of 30 W every 3 min) and two were performed using a ramp increment (load started at 100 W for 1 min followed by increments of 30 W·min(-1))...

Abdominal tumors are one of the most common types of pediatric cancer. Therefore, they should always be included in the differential diagnosis of abdominal masses. Here, we present the case of a child whose initial hypothesis of diagnosis contemplated this possibility. Later, it was demonstrated that the abdominal mass found was secondary to a common parasitosis. A 2-year old, moderately malnourished and pale white boy was referred with a history of a rapidly growing, well-limited, middle abdominal mass. The mass was 10 by 3 cm, hard and poorly movable, apparently involving both abdominal rectus muscles...

RATIONALE: Numerous types of flap coverage have been reported to prevent or to repair bronchopleural fistulas. Most of the flaps were harvested from chest area. However, these pedicled flaps might not be optimal for the patient who has undergone previous radiotherapy on pulmonary parenchyma because the pedicle artery of the flap might have been injured by irradiation. Therefore, an alternative flap outside of the chest area is necessary. PATIENT CONCERNS: A 61-year-old male was diagnosed of squamous cell carcinoma in right upper lobe lung (cT3N2M0, stage IIIa)...

Review of the English orthopaedic literature reveals no prior report of endoscopic repair of rectus abdominis tears and/or prepubic aponeurosis detachment. This technical report describes endoscopic reattachment of an avulsed prepubic aponeurosis and endoscopic repair of a vertical rectus abdominis tear immediately after endoscopic pubic symphysectomy for coexistent recalcitrant osteitis pubis as a single-stage outpatient surgery. Endoscopic rectus abdominis repair and prepubic aponeurosis repair are feasible surgeries that complement endoscopic pubic symphysectomy for patients with concurrent osteitis pubis and expand the less invasive options for patients with athletic pubalgia...

BACKGROUND: Patients with symptomatic umbilical, trocar, and/or epigastric hernias and concomitant rectus abdominis diastasis represent a growing clinical problem. The optimal management of this complex hernia situation is the subject of debate in the literature. This paper reports the early results of an innovative surgical technique aimed at managing this hernia situation. METHODS: Endoscopic-assisted linea alba reconstruction (ELAR) with mesh augmentation is a surgical technique long known in the literature for its good outcome for incisional hernia repair (myofascial release, overlapping herniorrhaphy, Gibson's operation, shoelace repair, anterior rectus sheath repair, dynamic patch plasty) via a small access route...

Rectus sheath haematoma is a rare cause of abdominal pain. It can be easily confused for other causes of acute abdomen and may even lead to unnecessary laparotomies. Our patient has the rectus sheath haematoma because of violent coughing and on presentation had no obvious clinical sign pointing to the same. Diagnosis was made by a CT scan of the abdomen, and patient was treated conservatively. Rectus sheath haematomas are usually present on the posterior aspect of the rectus muscles and thus may not be clinically appreciable...

Trauma refers to the destruction of tissues or organs by external forces and it is the most common cause of mortality and morbidity in children (1, 2). Injuries of the genitourinary tract may be the result of blunt (falls, sport injuries, motor vehicle accidents and sexual abuse) or penetrating (stab wounds, gun shots, falling onto sharp objects) injuries. The genitourinary tract is significantly injured in 2.9% of paediatric trauma patients 4.In the paediatric population, the kidney is the most affected organ in the genitourinary tract (>60% of all genitourinary tract injuries) 4...

Background.: Safe and efficacious modalities of perioperative analgesia are essential for enhanced recovery after surgery. Truncal nerve blocks are one potential adjunct for analgesia of the abdominal wall, and in recent years their popularity has increased. Transversus abdominis plane block (TAPB) and rectus sheath block (RSB) have been shown to reduce morphine consumption and improve pain relief after abdominal surgery. These blocks typically require large volumes of local anaesthetic (LA)...

The abdominal muscle activity has been shown to be variable in subjects with chronic obstructive pulmonary disease (COPD) when respiratory demand increases and their recruitment pattern may change the mechanics, as well as the work and cost of breathing. The scientific evidence in subjects "at risk" for the development of COPD may be important to understand the natural history of this disease. This study aims to evaluate the effect of inspiratory and expiratory loads on the abdominal muscle activity during breathing in subjects "at risk" for the development of COPD and healthy...
