The effects of muscle hypotonia and weakness on balance: A study on Prader–Willi and Ehlers–Danlos syndrome patients

Research in Developmental Disabilities, 2011
Prader-Willi syndrome (PWS) and Ehlers-Danlos syndrome (EDS) are two different genetical disorders both characterized, among other features, by muscular hypotonia. Postural control seems to be impaired in both conditions. The aim of the present study was to quantitatively compare postural control in adult PWS and EDS using stabilometric platform to ...

[Tonus of respiratory muscles in acetycholine hypotonia (author's transl)].

Zeitschrift fur Erkrankungen der Atmungsorgane, 1976
The importance of respiratory muscles in relation to circulation and ventilation was investigated in acute hypotonia after acetylcholin injection. The tonus of respiratory muscles was assessed by measuring the circumference of chest and abdomen. Changes of volume of the body cavities were examined by body plethysmography. A significant relation between

Restructuring of sleep and reversal of REM-induced supraspinal hypotonia of respiratory muscles following bilateral phrenicotomy

Neuroscience Letters, 1992
The long-term effect of diaphragm paralysis on respiratory system function is still not clear. We monitored changes in breathing pattern and the sleep/wake cycle in a dog before and after bilateral phrenicotomy. The post-operative observation extended over 6 months.

D-2-Hydroxyglutaric Aciduria: Hypotonia, Cortical Blindness, Seizures, Cardiomyopathy, and Cylindrical Spirals in Skeletal Muscle

Journal of Child Neurology, 1997
An infant girl was demonstrated to have D-2-hydroxyglutaric aciduria, the fifth case described and the first with muscle biopsy of this rare organic aciduria that differs clinically and genetically from the more common L-2-hydroxyglutaric aciduria.

[Control of isometric muscle contraction in muscle hypotonia of central origin: EMG mapping analysis].

EEG-EMG Zeitschrift fur Elektroenzephalographie, Elektromyographie und verwandte Gebiete, 1993
Electromyographic and mechanographic investigations in patients with muscular hypotonia, which is, for instance, a side-effect after stereotactic treatment of tremor syndromes, permit the presumption that in this sensomotor open-loop situation the decreased muscular resistance to stretching during isometric contraction (initial stiffness) is caused by ...

LIGHT AND ELECTRON MICROSCOPIC STUDIES OF "MYOGRANULES" IN A CHILD WITH HYPOTONIA AND MUSCLE WEAKNESS.

Canadian Medical Association journal, 1996
Examination by light and electron microscopy of more than 100 muscle biopsies revealed one very unusual case. A 4-year-old boy with non-progressive muscle weakness and hypotonia was found to have small particles, termed "myogranules", in many muscle fibres from two gastrocnemius biopsies.

Fiber density in congenital muscle fiber type disproportion. II. Congenital muscle hypotonia and hip dislocation.

Electromyography and clinical neurophysiology, 1991
Our previous paper presenting electromyographic findings in patients with congenital fiber type disproportion myopathy, confirmed the myogenic character of the disease process. That group of patients was however fairly heterogenous regarding both the clinical features and the morphological changes in muscle fibers (e.g. cases with central cores).

[Effect of low-molecular nonelectrolytes and hypotonia on the contractile responses of frog sartorius muscles].

Tsitologiia, 1980
The potentiation of contractile responses during prolonged incubation of frog sartorius muscles in a conventional Ringer solution and in a calcium-free Ringer solution which contained 400 mM of urea, acetamide or ethylene glycol was observed when stimulation with single electric impulses and with caffeine was carried out.
