H-reflex recovery, H-amplitude and H/M ratio were recorded in 54 mice aged 3-12 weeks to study the motoneuron excitability and changes in it during various stages of development. The H-reflex recovery curve at 12 wk showed 3 phases: an early, relative facilitation (before 10 ms), an almost total inhibition at 10 ms and a rapid recovery thereafter. At 3 wk,… (More)
The effect of cutaneous tactile stimulation on motoneuron excitability was studied in 20 normal subjects and in patients of hemiplegia (n = 14) and paraplegia (n = 15) by plotting H-reflex recovery curves during application of twin pulses alone ("basal" H-reflex recovery curve), and twin pulses synchronized with electrical stimuli evoking tactile sensation… (More)
Spinal somatosensory evoked potentials (SEP) were recorded in 58 normal mice (C3H strain) divided into 4 groups according to age (3-, 6-, 9- and 12 weeks). Monopolar recordings of spinal SEP were made by subdermal needle electrodes from 3 vertebral levels, "low-lumbar", "high-lumbar" and "mid-thoracic", by stimulating the tibial nerve bilaterally at the… (More)
The primary aim of this study is to compare, the cephalometric hard tissue profile values and analysis between Tamil and Caucasian population. The study also aims to create a better understanding in the facial proportions of Tamil Nadu population and to have better diagnosis and treatment planning for orthognathic surgery for Tamil population in Tamil Nadu.
INTRODUCTION The slope of the osteotomy used for the genioplasty dictates the vertical change. The horizontal bony changes after advancement genioplasty are not identical to the intercortical bony changes, because the variety of osteotomy slopes result in different vertical changes. MATERIAL AND METHODOLOGY Ten of these patients had additional osteotomies… (More)
Gracile axonal dystrophy (GAD) is an inherited neurodegenerative disease in the mouse with progressive sensory ataxia and motor paresis. Electromyographic examination was conducted in 25 unanaesthetized GAD mice and 24 controls of the same strain during 6, 9 and 12 wk of postnatal life. Among 9 and 12 wk old mice, about 75% showed resting spontaneous… (More)
H-reflex latency, proximal conduction velocity and distal proprioceptive conduction velocity were studied along with distal motor and sensory conduction in 38 patients of chronic obstructive lung disease grouped according to age and duration of the disease, as well as in 35 age-matched smoker controls and 14 non-smoker controls. The mean values of all the… (More)
H-reflex recovery by twin pulses was recorded serially in 10 paraplegics for 5 months and in 23 hemiplegics for 2 months after the lesion. Fifty-one normal subjects acted as controls. The effect of cutaneous tactile stimulation was also studied simultaneously by applying electrical stimuli synchronized with twin pulses to the skin over the lateral border of… (More)
