Microvascular Free Tissue Transfer of the Rectus Abdominis Muscle in Dogs
… assess donor site morbidity and survival of the rectus abdominis muscle with an overlying skin graft after free tissue transfer to a medial femorotibial defect in dogs. Study Design - Experimental study Sample Population: Phase one - six canine cadavers / Phase two - seven adult mixed breed dogs …

Investigação do início de ativação de músculos do tronco durante realização de tarefa motora em homens com e sem dor lombar.
… were statistically significant for the upper rectus abdominis, lower rectus abdominis and external oblique muscles at speeds of 120°/s and 90°/s; And only for the upper rectus abdominis at 60°/s. These results indicate the presence of co-contraction between the flexor and extensor muscles of …

Muscle-specific considerations for aging human skeletal muscle
… size via computed tomography of the quadriceps (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius), hamstrings (biceps femoris short and long heads, semitendinosus, semimembranosus), psoas, rectus abdominis, lateral abdominals (obliques and transversus abdominis), and …

Investigation and empirical evaluation of inputs to optimization-based biomechanical trunk models
… monitored were well predicted: left and right rectus abdominis, left external oblique, and left and right erector spinae. The left and right latissimus dorsi were poorly predicted by the models, which was due to the use of the muscle in shoulder Stability which was not accounted for in trunk …

INCREASE IN 1RM BACK SQUAT AFTER ABDOMINAL STABILIZING MANEUVERS
… Mean-normalized surface electromyography of the rectus femoris, biceps femoris, gluteus maximus, rectus abdominis, external oblique and erector spinae were analyzed in well trained individuals (n=13). A 1RM back squat protocol was performed under three conditions: control session, AB and AH. A …

The effect of idiopathic Parkinson's disease on seated trunk reactions
… which, bilateral electromyography (EMG) (rectus abdominis (RA), external oblique (EO), and erector spinae (EST9, L3)) and 3-D kinematic measures were recorded while participants were seated on a modified chair and received unexpected perturbations, 7° at 40°/sec, in four different …

Core stability of undergraduate collegiate dancers: an investigation of pilates on core stability and dance performance
… and found no significant differences in lower rectus abdominis engagement. However, pelvic alignment issues in the FGCT may have influenced results, as it does not consider dance-specific alignment. Study 2 explored the effects of a Pilates Mat routine on modern dance performance and core …

Kinetic studies of the spasmogenic effects of serotonin and isolates from Byrsonima crassifolia leaves on rat fundus
… and nicotinic effects on rat jejunum and frog rectus abdominis. Serotonin (5-HT) and HOAcE curves in fundus were parallel and 5-HT potency was 6,037 times that of HOAcE (95% confidence limits: 4,624-7,852). The pD<sub>2</sub> (affinity constant) for 5-HT was 7.96 (7.92-8.00) with pargyline …

Optical sensors for the in vivo assessment of flap perfusion in plastic surgery
… head and neck free flap surgery where a Vertical Rectus Abdominis Myocutaneous (VRAM) flap was used following total petrosectomy. Also, two patients undergoing reconstructive surgery of the oesophagus using jejunum free flaps were also recruited into the study. For this study a purpose build …

An investigation into the ultrastructural parameters of abdominal muscles in children and adolescents with spastic type cerebral palsy and the effect on postural muscle performance
… oblique (EO), internal oblique (IO), transversus abdominis (TrA) and rectus abdominis (RA) - were thicker in the STCP group than in the TD group. The EO, IO and TrA muscles in the STCP group were thicker at rest than in individuals with TD. The MAP's of EO, IO and TrA in the STCP group decreased …

The Validity and Reliability of Ultrasound as a Tool for Assessing Skeletal Muscle Characteristics in the Pediatric Population
… muscle thickness, (mT) of the psoas major and rectus abdominis (RA), two key trunk stabilizing muscles, obtained by a radiologist compared to a physical therapist (PT) (Aim1a) and the intra-rater reliability of the same measurements obtained at multiple timepoints by the PT (Aim1b). The second …

Biomechanical Assessment of Varied Lifting Tasks With and Without Passive Back Support Exoskeletons
… seen in the biceps femoris, longissimus, and rectus abdominis, with Bend Walk generally being the most taxing activity. Overall, there were minimal differences while rising up from any of these postures with most changes seen in the biceps femoris. Rising Up also generally had a higher peak …
