Passive muscle-tendon amplitude may not reflect skeletal muscle functional excursion.
PURPOSE To quantify the gain in muscle mobility with progressive release of surrounding connective-tissue structures and to compare this property with the known architecture of each muscle. METHODS Each of 5 different muscle tendon units (extensor carpi radialis brevis, extensor carpi radialis longus, flexor carpi ulnaris, flexor digitorum superficialis, pronator teres) was released from its ...
متن کاملSpastic wrist flexion in cerebral palsy. Pronator teres versus flexor carpi ulnaris transfer
OBJECTIVE Analize data on patients submitted to transfer of the pronator teres (PT) or the flexor carpi ulnaris (FCB) to the extensor carpi radialis longus/brevis (ECRL/B) in order to correct flexed wrist deformity in patients with cerebral palsy. METHOD Patients were divided into two groups: PT group and FCU group to ECRL/B. The results were evaluated by goniometry and by the functional hand...
متن کاملModulation of brachioradialis motoneuron excitabilities by group I fibers of the median nerve in humans.
Group I fibers from muscle spindles and Golgi tendon organs modulate motoneuron excitabilities to coordinate smooth movements. In this study, to elucidate the effects of group I fibers of the median nerve (MN) on the excitabilities of the brachioradialis (BR), we evaluated the changes in the firing probability of a BR motor unit after electrical conditioning stimulation (CS) to MN with a post-s...
متن کاملThe effect on forearm and shoulder muscle activity in using different slanted computer mice.
BACKGROUND Frequently using non-slanted computer mice will cause musculoskeletal discomfort and symptoms in forearms and shoulders. Ergonomic mice with different slanted angles may have various effects on forearm and shoulder muscle activity. METHODS All of the twelve subjects performed the same text-editing task with the five different slanted mice. The muscle activity of extensor carpi ulna...
متن کاملA pilot study to measure upper extremity H-reflexes following neuromuscular electrical stimulation therapy after stroke.
Upper extremity (UE) hemiparesis persists after stroke, limiting hand function. Neuromuscular electrical stimulation (NMES) is an effective intervention to improve UE recovery, although the underlying mechanisms are not fully understood. Our objective was to establish a reliable protocol to measure UE agonist-antagonist forearm monosynaptic reflexes in a pilot study to determine if NMES improve...
