Denervation processes are strongly associated with the symptoms experienced in post-polio syndrome. Individuals with post-polio syndrome undergo a continuous cycle of denervation and reinnervation that occurs after acute poliomyelitis. Over time, this cycle leads to an increase in the size of motor units in skeletal muscle fibers. Eventually ...
There are several treatments for spasmodic torticollis, the most commonly used being botulinum toxin injections in the dystonic muscle of the neck. Other treatments include sensory trick for a mild occasional twinge, oral medications, and deep brain stimulation. Combinations of these treatments have been used to control spasmodic torticollis.

Dystonia is often intensified or exacerbated by physical activity, and symptoms may progress into adjacent muscles. [ 4 ] The disorder may be hereditary or caused by other factors such as birth-related or other physical trauma , infection , poisoning (e.g., lead poisoning ) or reaction to pharmaceutical drugs , particularly neuroleptics , [ 3 ...
Motor neuron diseases affect both children and adults. [5] While each motor neuron disease affects patients differently, they all cause movement-related symptoms, mainly muscle weakness. [6] Most of these diseases seem to occur randomly without known causes, but some forms are inherited. [2]
Symptoms of neuromuscular disease may include numbness, paresthesia, muscle atrophy, a pseudoathletic appearance, exercise intolerance, myalgia (muscle pain), fasciculations (muscle twitches), myotonia (delayed muscle relaxation), hypotonia (lack of resistance to passive movement), fixed muscle weakness (a static symptom), or premature muscle ...
Spinal and bulbar muscular atrophy (SBMA), popularly known as Kennedy's disease, is a rare, adult-onset, X-linked recessive lower motor neuron disease caused by trinucleotide CAG repeat expansions in exon 1 of the androgen receptor (AR) gene, which results in both loss of AR function and toxic gain of function.
Muscle weakness is a lack of muscle strength. Its causes are many and can be divided into conditions that have either 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.
Electromyographic studies and nerve conduction studies show normal motor conduction velocity and latency with decreased amplitude of compound muscle action potentials. Pathologically, it is a noninflammatory axonopathy without demyelination. [3] Antibodies attack the coating of the motor neurons without causing inflammation or loss of myelin ...
