Motor disorders are disorders of the nervous system that cause abnormal and involuntary movements. They can result from damage to the motor system. [1]Motor disorders are defined in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) – published in 2013 to replace the fourth text revision – as a new sub-category of neurodevelopmental disorders.
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]
A neuromuscular disease is any disease affecting the peripheral nervous system (PNS), [a] the neuromuscular junctions, or skeletal muscles, all of which are components of the motor unit. [4] Damage to any of these structures can cause muscle atrophy and weakness. Issues with sensation can also occur. Neuromuscular diseases can be acquired or ...
Symptoms of locomotive syndrome include limitations in joint mobility, pain, balance disorder, malalignment and gait abnormality. [2] Locomotive syndrome is commonly caused by chronic locomotive organ diseases. Diagnosis and assessment of locomotive syndrome is done using several tests such as the stand-up and two-step tests.

Cerebellar degeneration can result in disorders in fine movement, posture, and motor learning in humans, due to a disturbance of the vestibular system. This condition may not only cause cerebellar damage on a temporary or permanent basis, but can also affect other tissues of the central nervous system, those including the cerebral cortex ...
NMT is a diverse disorder. As a result of muscular hyperactivity, patients may present with muscle cramps, stiffness, myotonia-like symptoms (slow relaxation), associated walking difficulties, hyperhidrosis (excessive sweating), myokymia (quivering of a muscle), fasciculations (muscle twitching), fatigue, exercise intolerance, myoclonic jerks and other related symptoms.
Peripheral neuropathy is a general term that indicates any disorder of the peripheral nervous system. [2] The name of the disorder itself can be broken down in order to understand this better; peripheral: in regard to peripheral neuropathy, refers to outside of the brain and spinal cord; neuro: means nerve related; -pathy; means disease. [1]
Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is an autosomal recessive late-onset heredodegenerative multisystem neurological disease. The symptoms include poor balance and difficulty walking. Chronic cough and difficulty swallowing may also be present.
