Infant Floppy Clinical Trial
Official title:
Causes of Peripheral Hypotonia in Children Attending Assiut University Children Hospital
Hypotonia is a common manifestation in infants and children.It includes several clinical
conditions that do not always lead to a favorable outcome .Thus, it is important to make
early diagnosis to decide on the treatment and follow up of these cases. Hypotonia is a state
of low muscle tone (The amount of tension or resistance to stretch on a muscle), often
pointing to reduced muscle strength.
Hypotonia is not a specific medical disorder, but a potential manifestation of several
diseases and disorders, that affect motor nerve control by the brain or muscle strength.
Criteria of peripheral hypotonia are : absent or depressed tendon reflexes , failure of
movements on postural reflexes ,fasciculation with or without muscle atrophy .A sequential
scheme of localization would begin with the anterior horn cell (AHC), and progress to the
peripheral nerve , neuromuscular junction (NMJ) and the muscle itself.
Electroneuromyography (ENMG) provides useful information on many neuromuscular diseases. In
addition nerve conduction study is also helpful to identify the most common peripheral
disorders causing hypotonia in these children.
The initial approach to hypotonia is to determine whether the problem is due to central or
peripheral origin.This is of crucial importance when forming a plan for diagnostic
investigations and management.
Many muscle diseases share common clinical features that may lead to laboratory diagnosis by
using enzyme levels that are affected in some of these diseases(e.g creatine phosphokinase ).
However the use of serum creatine phosphokinase level may not possibly differentiate between
various muscle diseases . The selective involvement of certain muscles is a key to the
diagnosis of muscle disease].
High resolution ultrasound allows visualization of the muscle, nerve and adjacent structures
and can offer real-time information regarding neuromuscular diseases. It can be used as a
helping tool to electrodiagnosis with estimation of the serum creatine phosphokinase levels
of these cases.
The aim of this work :is to give a profile of the causes of peripheral hypotonia in infant
and children attending Assiut University Children Hospital during one year of the study .
Besides full clinical assessment of the cases including birth history , developmental
history, age, sex, and duration of illness as well as age of onset of observed weakness will
be recorded. Full neurological examination will be done in all cases .Cases will have serum
creatine phosphokinase levels, electromyography and nerve conduction studies done as
indicated.Cases will also have real time muscle ultrasonography done.
- Our results will be compared with the results obtained by other investigators .
- Statistical analysis : correlation studies will be done between the various methods of
investigations used .Chi2 test will be used to indicate the prevalence of the various
causes of hypotonia found in the study .
