19 Possible Causes for Clonus, Muscle Spasticity, Narrowing of Medullary Canal

  • Cervical Spondylosis

    […] of the medullary canal [14].[termedia.pl] Objective neurological deficit (upper motor neurone signs in the legs (eg, up-going plantars, hyperreflexia, clonus, spasticity); lower motor neurone signs in the arms (eg[patient.info] The main clinical features are localized wasting and weakness of the extrinsic and intrinsic hand muscles, but not accompanied by either sensory loss or spastic quadriparesis[ncbi.nlm.nih.gov]

  • Cervical Myelopathy

    This narrowing in the lower back (lumbar canal stenosis) produces only radiculopathy (pinched nerve) because the tip of the spinal cord called the conus medullaris is at the[necksolutions.com] Motor weakness in the extremities Gait difficulties ("spastic gait," hesitant and jerky) Myelopathic or "upper motor neuron" findings such as spasticity, hyperreflexia, clonus[emoryhealthcare.org] […] paresis, and spasticity; nerve root compression commonly causes early radicular pain, sometimes followed by weakness, hyporeflexia, and muscle atrophy.[merckmanuals.com]

  • Spinal Cord Compression

    Bilateral Babinski's sign and ankle clonus were positive. He had no bladder or bowel dysfunction.[ncbi.nlm.nih.gov] Muscle spasticity can cause spasms in the legs or make them more difficult to control.[livestrong.com] In a CT scan, a bony tumor rising from the posterior wall of the T3 body narrowing the spinal canal, and the MRI spinal cord compression at the same level and the hydrosyringomyelic[ncbi.nlm.nih.gov]

  • Myelopathy

    Physical examination revealed significant increase in deep tendon reflexes in the lower extremities and clonus. Hoffman's sign was positive in the left upper extremity.[ncbi.nlm.nih.gov] […] paresis, and spasticity; nerve root compression commonly causes early radicular pain, sometimes followed by weakness, hyporeflexia, and muscle atrophy.[merckmanuals.com] This narrowing in the lower back (lumbar canal stenosis) produces only radiculopathy (pinched nerve) because the tip of the spinal cord called the conus medullaris is at the[necksolutions.com]

  • Lower Motor Neuron Syndrome with Late-Adult Onset

    -progressive proximal limb weaknessweakness -bulbar-bulbar weaknessweakness  upper motor neuron diseasesupper motor neuron diseases - spasticity- spasticity  - clonus- clonus[slideshare.net] Doctors can prescribe medications for reducing fatigue, muscle cramps, muscle spasticity, and excessive saliva or phlegm, as well as pain, depression, sleeping problems or[livescience.com] The spinal cord terminates in the conus medullaris (L1), which then become lumbosacral roots (cauda equina) descending through the lumbar spinal canal.[consultant360.com]

  • Quadriplegia

    Clonus is another symptom that is characterized by alternating, rapid muscle contraction and relaxation. This presents itself as tremors and scissoring of the limbs.[en.wikipedia.org] We evaluated the adverse events, walking time and distance, and the difference in muscle spasticity before and after HAL-training using a modified Ashworth scale (mAs).[ncbi.nlm.nih.gov] The MR images show the spondyloarthrotic changes and a narrow canal and the secondary myelopathy, with signal changes in medullary area [Images courtesy of the Neuroradiology[neupsykey.com]

  • Camurati-Engelmann Syndrome

    Rarely, clonus [ Neuhauser et al 1948 ], sensory loss, slurred speech, dysphagia, cerebellar ataxia, and bowel and bladder incontinence are reported [ Carlson et al 2010 ][ncbi.nlm.nih.gov] […] laxa, autosomal dominant PMM2-CDG (CDG-Ia) Hereditary paraganglioma-pheochromocytoma Hereditary congenital facial paresis Crisponi syndrome Abetalipoproteinemia Rippling muscle[checkrare.com] Certain bone regions (specifically, the endosteal and periosteal surfaces) become abnormally thickened and hardened, which in turn narrows the medullary canal.[encyclopedia.com]

  • Radiculomyelopathy

    […] on the right, and no clonus on the left.[orthobullets.com] The small muscles of the hands and feet are usually first affected, but muscle spasticity is absent. Primary lateral sclerosis - this is another rare type of MND.[patient.info] The spinal cord terminates in the conus medullaris (L1), which then become lumbosacral roots (cauda equina) descending through the lumbar spinal canal.[consultant360.com]

  • Cervical Cord Compression

    Clonus . Upon forcing the ankle to extend, the patient's foot rapidly beats up and down. Babinski reflex .[spine-health.com] An increase of muscle tone during these passive movements is referred to as "spasticity."[neuroanatomy.wisc.edu] This narrowing in the lower back (lumbar canal stenosis) produces only radiculopathy (pinched nerve) because the tip of the spinal cord called the conus medullaris is at the[necksolutions.com]

  • Narrow Cervical Spinal Canal

    There may be clonus and spasticity in the legs. Pulses and vascularity of the legs should be normal.[uscspine.com] TORG's method proposes that the index, smaller or equal to 0.80 identify a significant narrowing of the cervical canal diameter.[scielo.br] Hoffman sign, if present, has been shown to positively correlate with CSM. 11 A Babinski sign, ankle clonus, and Lhermitte phenomenon should be documented, if present.[now.aapmr.org]
