    • Spinal Epidural Hematoma
      Hyperreflexia Clonus

      At the neurological examination, he was found to have tetra-hyposthenia with tetra-hyperreflexia.[] Tetra-hyperreflexia unchanged, but the patient’s mobility and sensory ability improved significantly.[] The examination showed marked tetra-hyperreflexia, motor deficit involving the left upper arm, and frank hyposthenia on both legs.[]

    • Cervical Myelopathy
      Hyperreflexia Clonus

      •Pathological long tract signs will be seen consisting of Hoffman's, Babinski, clonus, finger escape and L’hermitte’s signs, in addition to hyperreflexia.[] On physical examination upper motor neuron signs are present including hyperreflexia, clonus, spasticity, Lhermitte’s phenomenon, up-going plantar response, and Hoffmann’s[] Clonus sign: nonvoluntary sustained movement of the ankle muscles with from passive continuous stretch.[]

    • Myelopathy
      Hyperreflexia Clonus

      […] 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[] Clark suggested that sensory findings usually include preservation of touch, loss of pain and temperature, loss of proprioception and vibration below the level of lesion. 2 Clonus[] […] with special emphasis in oncology practice. - Babinski's sign: - may not be present until myelopathy becomes severe; - upper motor neuron findings such as hyper-reflexia, clonus[]

    • Spinal Epidural Abscess
      Hyperreflexia Clonus

      A patient’s reflexes may vary from being absent to hyperreflexia with clonus (rhythmic muscle spasms or contractions) and extensor plantar responses (a/k/a Babinski responses[] Massive Disc Herniation, Spinal Epidural Abscess or Bony Metastasis) Vertebral Fractures, Osteomyelitis Cauda Equina Syndrome (CES) Note - Cord Compression is a UMN lesion (Hyperreflexia[] Patellar clonus was present, with hypoesthesia below D 9 level.[]

    • Strychnine Poisoning
      Hyperreflexia Clonus

      Hyperreflexia occurs if the animal's back is tapped.[] Progression to extreme stiffness and hyperreflexia, sometimes with generalised trembling and muscle twitching.[] The ten main symptoms of strychnine poisoning: Initial symptoms are tightness and twitching of the muscles, agitation and hyperreflexia.[]

    • Primary Progressive Multiple Sclerosis
      Hyperreflexia Clonus

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

    • Spinal Cord Lesion
      Hyperreflexia Clonus

      , hypertonicity, and clonus; - return of reflex activity below level of injury indicates end of spinal shock; - sacral sparing : - diff dx of incomplete lesions: - central[] Autonomic hyperreflexia is a serious condition and needs immediate treatment.[] […] of spinal function; - spinal shock (spinal cord concussion): - usually invovles 24-72 hour period of paralysis, hypotonia, & areflexia, and at its conclusion there may be hyperreflexia[]

    • Cerebral Palsy with Spastic Diplegia
      Hyperreflexia Clonus

      Ankle clonus.[] CP spasticity is characterized by increased muscle tone, hyperreflexia and tone that increases with velocity.[] Unilateral ankle clonus (usually).[]

    • Thoracic Spinal Cord Tumor
      Hyperreflexia Clonus

      Other signs evident upon physical examination may include spine tenderness, stiffening of gait, trophic changes of extremity, sensory loss, hyperreflexia, clonus, and scoliosis[]

    • Spinal Cord Infarction
      Hyperreflexia Clonus

      His motor and sensory exams and reflexes are normal although he does exhibit mild finger clonus.[] Initially areflexia is present due to spinal shock but, hyperreflexia and spasticity appear later The most common form is anterior spinal artery syndrome.[] Initial areflexia changes to hyperreflexia with the presence of Babinski signs.[]
