7 Possible Causes for Hyperactive Patellar Tendon Reflexes

  • Usher Syndrome Type 3B

    Definition A syndrome characterized by progressive vision and hearing loss during early childhood. Some patients have the so-called 'Charles Bonnet syndrome,' involving decreased visual acuity and vivid visual hallucinations. USH is a genetically heterogeneous condition characterized by the association of retinitis[…][uniprot.org]

  • Osteoma

    The biceps tendon reflex, patellar tendon reflex, and Achilles tendon reflex were hyperactive, and the Hoffman and Babinski reflex were positive bilaterally.[ncbi.nlm.nih.gov] The biceps, patellar, and Achilles tendon reflexes were hyperactive, and the Hoffman and Babinski reflexes were positive bilaterally.[ncbi.nlm.nih.gov]

  • Subacute Combined Degeneration of Spinal Cord

    Patient H had hyperactive reflexes of the upper limbs. Patellar tendon reflexes were hyperactive in patient A, reduced in patient H, and absent in patient I.[jnnp.bmj.com]

  • Muscular Fasciculation

    Deep tendon reflexes in the 4 limbs were asymmetrical that left limbs were hyperactive and right limbs brisk. Hoffman’s reflexes and patellar clonus were negative.[nnjournal.net]

  • Stingray Envenomation

    Patellar and Achilles tendon reflexes on the affected leg were hyperactive and there were no sensory changes.[toxinology.com]
