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.
A patient and doctor discuss congenital insensitivity to pain. For people with this disorder, cognition and sensation are otherwise normal; for instance, patients can still feel discriminative touch (though not always temperature [3]), and there are generally no detectable physical abnormalities.
There is no sensation of pain or discomfort, the muscle appears to simply ‘stop listening’ and gradually cease to move, often lengthening. As there is insufficient stress on the muscles and tendons, there will often be no delayed onset muscle soreness following the workout. Part of the process of strength training is increasing the nerve's ...
Weakness is a symptom of many different medical conditions. [1] The causes are many and can be divided into conditions that have true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy.
Acquired myasthenia gravis is the most common neuromuscular junction disease.(reference 7) Important observations were made by Patrick and Lindstrom in 1973 when they found that antibodies attacking the acetylcholine receptors were present in around 85% of cases of myasthenia gravis.(reference renamed form 13)(reference 36) The remaining ...
Since people with this condition are unable to sweat, they are unable to properly regulate their body temperature. [1] Those affected are unable to feel pain and temperature. [2] [3] The absence of pain experienced by people with CIPA puts them at high risk for accidental self-injury. Corneal ulceration occurs due to lack of protective impulses ...
DM2 preferentially affects muscles closer to or on the torso, including the neck flexors, hip flexors, and hip extensors. [5] Muscle pain is prominent in DM2. [5] Heart issues, while still potentially fatal, are less common and severe in DM2 than DM1. [2] Symptoms onset in early to late adulthood. [5]
This usually starts with the observation of bulk, possible atrophy or loss of muscle tone. Neuromuscular disease can also be diagnosed by various blood tests and using electrodiagnostic medicine tests [ 23 ] including electromyography [ 24 ] (measuring electrical activity in muscles) and nerve conduction studies .
