537 Possible Causes for Clonus, Hyperreflexia

  • Spinal Epidural Abscess

    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[] […] and sphincter dysfunction Incomplete spinal cord syndromes Unilateral motor or sensory deficits [ 10 ] Gait ataxia [10] Reflexes may vary from absent to hyperreflexia with clonus[]

  • Myelopathy

    […] 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[] A characteristic physical finding of CSM is hyperreflexia. The biceps and supinator reflexes (C5 and C6) may be absent, with a brisk triceps reflex (C7).[] […] on the right, and no clonus on the left.[]

  • Cervical Myelopathy

    […] on the right, and no clonus on the left.[] Upper motor neuron signs elicited were: a positive Hoffman’s bilaterally and hyperreflexia bilaterally. Babinski sign was negative bilaterally.[] Thus these medical signs will become pathological: Increased tension in the leg muscles (Hyperreflexia) Accentuated reflexes of the knee and ankle Forced extension of the[]

  • Spinal Cord Injury

    Upper motor neurone signs in the lower limbs (Babinski's sign: up-going plantar reflex, hyperreflexia, clonus, spasticity).[] Complications The following medical disorders are common complications seen in spinal cord injury patients: Blood pressure fluctuation due to autonomic hyperreflexia Decubitus[] Another problem with circulatory control is a potentially life-threatening rise in blood pressure (autonomic hyperreflexia).[]

  • Spastic Paraplegia

    The knee-jerk is excessive and ankle-clonus is easily obtained.[] Hyperreflexia, extensor plantar response and increased muscle tone are the recognized UMN signs where as the weakness, muscle wasting, hyporeflexia, muscle cramps, and fasciculations[] Ankle clonus, and extensor plantar responses are uniformly present. 41. Hoffman sign may be observed. 42.[]

  • Cervical Spondylosis

    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[] Some myelopathic signs include hyperreflexia of deep tendon reflexes of the upper and lower extremities, increased muscle tone or clonus, and the presence of pathological[] A characteristic physical finding of CSM is hyperreflexia. The biceps and supinator reflexes (C5 and C6) may be absent, with a brisk triceps reflex (C7).[]

  • Spinal Cord Lesion

    (spinal cord concussion): - usually invovles 24-72 hour period of paralysis, hypotonia, & areflexia, and at its conclusion there may be hyperreflexia, hypertonicity, and clonus[] Hyperreflexia ( Babinski, clonus) HypertoniaMain Menu Content Menu Legend Exit 15. R L Lesion of the right lateral spinothalamic tract at L1 produces what impairment?[] Hyperreflexia From my perspective, I have no bladder or bowl problems but I do have leg and arm pain (was told I have fibromyalgia 2 years ago) and have Hashimoto's (thyroid[]

  • Spinal Cord Infarction

    His motor and sensory exams and reflexes are normal although he does exhibit mild finger clonus. The patient was referred for an MRI of the cervical spine.[] Initially areflexia is present due to spinal shock but, hyperreflexia and spasticity appear later The most common form is anterior spinal artery syndrome.[] Hyperreflexia may follow initial symptoms, and a positive Babinski reflex may be elicited.[]

  • Spinal Epidural Hematoma

    At the neurological examination, he was found to have tetra-hyposthenia with tetra-hyperreflexia.[] […] exhibited low-grade fever (oral 37.5 C) and severe cervical paraspinal muscle spasm accompanied by 4/5 quadriparesis (based on muscle strength grading 0–5), left upper limb hyperreflexia[] Tetra-hyperreflexia unchanged, but the patient’s mobility and sensory ability improved significantly.[]

  • Eclampsia

    […] oedema O right upper quadrant tenderness O recently developed hypertension or equal to 170/110 mmHg with proteinuria 1 gram/24 hours or a rapid rise in blood pressure O clonus[] (NICHD) Definition (MSH) Onset of HYPERREFLEXIA; SEIZURES; or COMA in a previously diagnosed pre-eclamptic patient (PRE-ECLAMPSIA).[] Signs & Symptoms Most commonly asymptomatic, but can cause: Flu-like symptoms Vomiting pulse Hyperreflexia and Clonus ( 3 beats) Seizures – indicated eclampsia Headache Visual[]
