Clarinet Thumb-rest Function: The Pedagogy of Positioning and Electromyography Evidence
… effect of rest position in the biceps brachii, abductor pollicis brevis, abductor pollicis longus, extensor carpi radialis and flexor carpi ulnaris. There was no main effect of hand size in the muscles. Because opposing muscles had contrasting patterns of activation regardless of hand size, …

Sensory re-weighting for balance control and the effects of ankle foot orthoses and stance width: A comparison of people with diabetic peripheral neuropathy and healthy participants
… stimulation induced by vibration of the hip abductors in healthy participants. Study 2 investigated the effect of an acute reduction of somatosensory information induced by cooling in healthy participants on the response to ankle evertor and hip abductor vibration. This provided a model of …

Effects of foot placement on resultant joint moments in the lower extremity joints during the squat
… In terms of stance width, the largest hip abductor moment (HAB), knee abductor moment (KAB), and ankle everter moment (AE) were produced in the narrow stance, followed by the medium stance, and the wide stance revealed the smallest values. In terms of toe angle, the toe out condition was …

Cursorial Adaptations in the Forelimb of the Giant Short-Faced Bear, <em>Arctodus simus</em>, Revealed by Traditional and 3D Landmark Morphometrics
… and provide additional evidence for reduced abductor/adductor and supinator/pronator musculature, more restricted parasagittal motion, increased stride length, and lighter and more packed distal elements. Forelimb skeletal morphology therefore supports the hypothesis that <i>A. simmus</i> …

Motor control and directional accuracy of phonotaxis in female field crickets
… the antenna towards the median line, and the abductor muscle that abducts it laterally. The activity of the adductor muscle is coupled to the adduction movement of the antenna during the contralateral presentation of the calling song, while the activity of the abductor muscle is coupled to the …

Ultraschalldiagnostik am Karpalgelenk des Rindes
… distally one step at a time. Only the musculus abductor pollicis longus had to be examined in an oblique direction. The examination procedure was applied to 11 carpal joints of healthy cattle of all ages and sexes. The carpal flexor and extensor tendons, partially their tendon sheaths, the …

The Effect of Natural Running on Human Foot Strength
… significantly increased muscle volume in the abductor digiti minimi (25%, p= 0.009) and reduced stiffness in the longitudinal arch (p= 0.013). The abductor in flexing the fifth digit metatarsal phalangeal joint enhances the tie-rod function (windlass mechanism) of the plantar aponeurosis. …

A qualitative holographic study of hemipelvic and acetabular deformation caused by different hip prostheses
… the models included tensioning of the simulated abductor muscles for the hemi-pelvic and femoral loading for the prosthesis/cement/bone interface study. The experimental method employed was real-time holographic interferometry, a stress analysis technique recently used in the biomechanical field, …

Phylogenetic Analysis of the Australian Genus <em>Pseudophryne</em> (Myobatrachidae) using Morphological Characters.
… (2) wide frontoparietal fontanelle, (3) m. abductor indicis longus arising from the humerus and radioulna, and (4) neopalatine in contact with the maxilla. The columella is shown as a relatively plastic characteristic, present ancestrally but lost in the common ancestor to …

Investigation of Upper Limb Kinematics and Corticospinal Pathway Activity Early After Stroke
… biceps, extensor carpi radialis (ECR), and abductor pollicis brevis (APB) in neurologically intact adults. The results demonstrate variable reliability; the lower end of the confidence interval was below acceptable reliability (ICC < 0.70) for many measures. The 95% confidence intervals (CI) …

The Level of Antiacetylcholine Receptor Antibodies in the Patients with Myasthenia Gravis
… was checked in the orbicularis oculi and the abductor digiti minimi muscles. Twenty six among 33 included patients were taken steroids or other immunosuppressants. The levels of the acetylcholine receptor antibody correlated with the maximal decremental rate score of RNS tests (r = 0.5, P < …

An examination of age-related differences in lower extremity joint torques and strains in the proximal femur during gait
… be sensitive to muscle forces, particularly hip abductor forces. Strains in the sub-trochanteric region tended to be larger than those in the femoral neck, and less sensitive to muscle forces. These results increase our understanding of neuromuscular changes that occur with age, and the effects …

ADAPTATIONS FOLLOWING UPPER EXTREMITY RESISTANCE TRAINING IN OLDER ADULTS
… and shoulder adductor volume (p=0.009). Shoulder abductor and adductor muscle volumes (R2>0.40, p<0.008 for both) and maximum isometric joint moments at the shoulder (R2>0.59, p<0.11) were significant predictors of functional strength. Eight of the 12 muscles identified using simulation as having …
