Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder.The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles and rigidity. [1]
Rigid spine syndrome, also known as congenital muscular dystrophy with rigidity of the spine (CMARS), is a rare and often debilitating neuromuscular disorder.It is characterized by progressive muscle stiffness and rigidity, particularly in the spine, which can severely limit mobility and impact quality of life.
Furthermore, muscle biopsy does not reveal any deficiency. [1] Walker–Warburg syndrome at the beginning a progressive weakness and low muscle tone at birth or during early infancy; small muscles; the majority of affected children do not live more than 3 years of age. Eye structure problems are present, with accompanying visual impairment.
Cerebral palsy (CP) is a group of movement disorders that appear in early childhood. [1] Signs and symptoms vary among people and over time, [1] [3] but include poor coordination, stiff muscles, weak muscles, and tremors. [1] There may be problems with sensation, vision, hearing, and speech. [1]
Postsynaptic symptoms in infants include severe muscle weakness, feeding and respiratory problems, and delays in the ability to sit, crawl, and walk. Synaptic symptoms include early childhood feeding and respiratory problems, reduced mobility, curvature of the spine, and weakness, which causes a delay in motor milestones.
For example, when learning a row, focus first on driving your elbows behind you rather than every component of the movement (like engaging the biceps muscle, activating the rhomboid, etc ...
Gowers's sign, toe walking, multiple contractures of the joints (especially the fingers: 'Bethlem sign'), skin abnormalities, and muscle weakness (proximal more than distal) are typical signs and symptoms of the disease. Initially, in early childhood, there may also be joint laxity.
Hypotonia is a state of low muscle tone [1] (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength. Hypotonia is not a specific medical disorder, but a potential manifestation of many different diseases and disorders that affect motor nerve control by the brain or muscle strength.
