Cancer of the oral cavity is a most devastating disease that causes a significant disfigurement of the patient with severe morbidity and mortality. It is a challenging disease in its nature and management affecting not only the function but also the cosmesis of the afflicted patients. Despite improvement in the diagnostic and management methods, the prognosis of oral cancer is still unpredictab...

1. Certain muscles in the hind foot of rats were partially paralysed by applying tetrodotoxin to part of their motor innervation. In these muscles motor nerve sprouting occurred from the terminals of the unblocked axons. The extent of sprouting was compared with that seen in totally paralysed and in partially denervated muscles. 2. Action potentials were blocked in the medial and lateral planta...

Purpose: A proper warm-up method can be used as a strategy to improve performance of athletes in various sport fields. The aim of present study was to compare the effect of two traditional and post-activation potentiation warm-up methods on electromyographic variables of lower extremity muscles during squat jump. Methods: Fourteen trained male athletes were randomly performed three different p...

Masticatory and tongue muscle activity was examined polysomnographically in 14 patients with sleep apnea syndrome and six snorers. The all-night polysomnographic recordings included electromyograms (EMG) of the genioglossal, the masseter and the inferior head of the lateral pterygoid muscles, nasal airflow and thoracoabdominal respiratory effort. The apneas were defined and classified into thre...

Purpose To investigate changes in volumes of extraocular muscle (EOM) compartments in unilateral superior oblique (SO) palsy using magnetic resonance imaging (MRI). Methods High-resolution, surface-coil MRI was obtained in 19 patients with unilateral SO palsy and 19 age-matched orthotropic control subjects. Rectus EOMs and the SO were divided into two anatomic compartments for volume analysis...

Weight training is an integral part of most athletic conditioning programs; yet, the effect of these programs on neuromuscular function remains unclear. To examine the neuromuscular effects of training and conditioning at the knee joint, 32 volunteers (16 men and 16 women; average age, 25.4 years) were placed into one of four groups: isokinetic, isotonic, agility, or control. Each group trained...

The present study was designed to explore how the interaction between the fascicles and tendinous tissues is involved in storage and utilization of elastic energy during human walking. Eight male subjects walked with a natural cadence (1.4 +/- 0.1 m/s) on a 10-m-long force plate system. In vivo techniques were employed to record the Achilles tendon force and to scan real-time fascicle lengths f...

Children with cerebral palsy frequently walk with excessive internal rotation of the hip. Spastic medial hamstrings or adductors are presumed to contribute to the excessive internal rotation in some patients; however, the capacity of these muscles to produce internal rotation during walking in individuals with cerebral palsy has not been adequately investigated. The purpose of this study was to...

The activity of the biceps brachii and lateral head of the triceps brachii were compared during the contact placing reactions elicited by tactile stimuli applied to the lateral, medial or dorsal aspects of the forepaw to verify the hypothesis that common movement strategy was used in all these reactions. Similar latencies and patterns of muscle activation have been found for the medial and dors...
