665 Possible Causes for Clonus, Hyperreflexia

  • Stroke

    Focal seizures were distinguished clinically from clonus, spasms, and recurrent strokes. 8 9 Electroencephalograms were not routinely performed.[doi.org] An examination showed decreased strength on the right side, with hyperreflexia and an up-going plantar response.[ncbi.nlm.nih.gov]

  • Chronic Kidney Insufficiency

    […] filtration rate [eGFR] 15 mL/min/1.73 m 2 ), neuromuscular symptoms may be present, including coarse muscular twitches, peripheral sensory and motor neuropathies, muscle cramps, hyperreflexia[merckmanuals.com]

  • Cervical Spondylosis

    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] Eleven patients (58%) had lower limb hyperreflexia or Babinski sign.[ncbi.nlm.nih.gov] On physical examination, you may find some or many of the following: clonus or spasticity of the lower extremities sensory changes (light touch, pinprick sensation, or temperature[americannursetoday.com]

  • 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] Clinical hyperreflexia was tested at the MCP joint, using a six-axis load cell.[ncbi.nlm.nih.gov] […] with radicular symptoms - 16% had pure myelopathic symptoms - 23% had a combination of myelopathic and radiculopathy - upper motor neuron findings such as hyper-reflexia, clonus[wheelessonline.com]

  • Cervical Myelopathy

    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] BACKGROUND: Gait dysfunction associated with spasticity and hyperreflexia is a primary symptom in patients with compression of cervical spinal cord.[ncbi.nlm.nih.gov] Increased tension in the leg muscles (Hyperreflexia) Accentuated reflexes of the knee and ankle Forced extension of the ankle may cause the foot to beat up and down rapidly (clonus[dr-bertagnoli.com]

  • Spastic Paraplegia

    This case showed spasticity and hyperreflexia with pathological reflexes and ankle clonus as well as muscle weakness in all extremities.[ncbi.nlm.nih.gov] The knee-jerk is excessive and ankle-clonus is easily obtained.[henriettes-herb.com] On neurological examination, he showed hyperreflexia, spasticity, and weakness in the lower extremities and bilateral Babinski reflexes.[ncbi.nlm.nih.gov]

  • Primary Progressive Multiple Sclerosis

    Affected individuals may have tremors, muscle stiffness (spasticity), exaggerated reflexes (hyperreflexia), weakness or partial paralysis of the muscles of the limbs, difficulty[icdlist.com]

  • Muscle Spasticity

    The presence of clonus can be a sign of neurologic problems but alone is not enough for diagnostic purposes.[pediatricservices.com] Spasticity is usually accompanied by HYPERREFLEXIA and variable degrees of MUSCLE WEAKNESS.[profiles.umassmed.edu] These address the degree of muscle tone, the frequency of spontaneous spasms and the extent of hyperreflexia.[bjmp.org]

  • Subacute Transverse Myelitis

    There was no clonus. Deep tendon reflexes were traced in the upper extremities, 2 at the knees, 2 at the ankles. Toe signs were silent. There was no spine tenderness.[egms.de] An areflexic cystometrogram tended to change to a low compliance bladder, followed by detrusor hyperreflexia or a normal cystometrogram.[nature.com] No ankle clonus was observed. Babinski’s sign was the plantar response. The anal sphincter tone was intact.[karger.com]

  • Pyramidal Tract Lesion

    In a patient with clonus, a muscle stretch elicits alternating contractions of agonist and antagonist muscle groups.[courses.washington.edu] […] decussation causes impairment of movement in the opposite body-half, which is especially severe in the arm and leg and is characterized by muscular weakness, spasticity and hyperreflexia[medical-dictionary.thefreedictionary.com] Symptoms include an increase in the muscle tone in the lower extremities, hyperreflexia, positive Babinski and a decrease in fine motor coordination.[sideeffects.embl.de]
