BACKGROUND Muscle injury is the most common injury type in professional soccer players. Despite this, risk factors for common lower extremity injuries remain elusive. PURPOSE To evaluate the effects of various player- and match-related risk factors on the occurrence of lower extremity muscle injury in male professional soccer. STUDY DESIGN Cohort study; level of evidence, 2. METHODS Betwe...

The exact homologies of tetrapod jaw muscles remain unresolved, and this provides a barrier for phylogenetic analysis and tracing character evolution. Here, lepidosaur jaw muscles are surveyed using direct examination of species from 23 families and published descriptions of species from 10 families. A revised nomenclature is applied according to proposed homologies with Latimeria. Among lepido...

The individual rate of onset of action of tubocurarine and alcuronium has been examined with and without a priming dose of the same agent or the other agent, by measurement of changes in the evoked compound electromyogram of the adductor pollicis muscle. Priming was associated with acceleration of the onset of neuromuscular block.

De Ruiter, C. J., and A. De Haan. Shortening-induced depression of voluntary force in unfatigued and fatigued human adductor pollicis muscle. J Appl Physiol 94: 69–74, 2003. First published September 13, 2002; 10.1152/japplphysiol.00672.2002.—The goals of this study were to investigate adductor pollicis muscle (n 7) force depression after maximal electrically stimulated and voluntarily activate...

Wassel VI radial polydactyly is associated with metacarpal adduction and deviation of the metacarpophalangeal joint ulnar duplicate. The soft tissue abnormalities responsible for these deformities were characterized using preoperative multi-planar three-dimensional ultrasound intraoperative observation in four patients. In all patients, abductor pollicis brevis superficial head flexor inserted ...

Myosin from molluscan adductor muscle is regulated directly by Ca2+ binding. In the absence of Ca2+ the ATPase activity is greatly inhibited. We review the application of transient kinetic methods to this system and show how they can be simple to perform and less ambiguous than steady-state methods.

This report describes two cases of severe adductor muscle spasm during transurethral resection of bladder tumours and subsequent successful management with the help of obturator nerve block. Obturator nerve blocks are useful during surgery to remove large, advanced tumours in the distal lateral wall of the bladder.

BACKGROUND Skeletal muscle wasting in acute lung injury (ALI) patients increases the morbidity and mortality associated with this critical illness. The contribution of laryngeal muscle wasting to these outcomes is unknown, though voice impairments and aspiration are common in intensive care unit (ICU) survivors. We evaluated the intrinsic laryngeal abductor (PCA, posterior cricoarytenoid), addu...

OBJECTIVE To compare the pattern of pelvic girdle muscle activation in normal subjects and hemiparetic patients while stepping and maintaining standing balance. DESIGN Group comparison. METHOD Seventeen patients who had regained the ability to walk after a single hemiparetic stroke were studied together with 16 normal controls. Median interval between stroke and testing was 17 months. Ampli...

The isometric and isotonic contractile properties of the cross-striated adductor muscle of the bay scallop (Argopecten irradians) were measured in vitro at 10, 15 and 20 degrees C. The length at which twitch force was maximal as a function of the closed length in situ (L0/Lcl) averaged 1.38 +/- 0.01 (mean +/- S.E.M.) at 10 degrees C. This length is very close to the typical length at maximum ga...
