15 Possible Causes for Absent Ankle Reflex, Decreased Deep Tendon Reflexes in Both Legs

  • Peripheral Neuropathy

    Most people with PN have reduced or absent ankle reflexes (involuntary responses to a stimulus).[thebody.com] Classically, ankle jerk reflex is absent in peripheral neuropathy.[en.wikipedia.org] A physical examination will involve testing the deep ankle reflex as well as examining the feet for any ulceration.[en.wikipedia.org]

  • Diabetic Polyneuropathy

    The ankle tendon reflex was absent in almost half of our patients (40.4 %).[em-consulte.com] reflexes: Absent Associated with foot ulcers in chronic DM 7x increase Age: Middle-aged & elderly Location: Soles of feet Neuropathic osteoarthropathy : Frequency increased[neuromuscular.wustl.edu] In prospective studies, the three main independent predictors for foot ulceration have been shown to be absent ankle tendon reflex, impaired monofilament pressure sensation[em-consulte.com]

  • Cauda Equina Syndrome

    .  Physical Exam:  Right plantar flexor weakness, absent right ankle reflex, and decreased anal sphincter tone.  Findings consistent w/ CES  Referral:  Medically evacuated[slideshare.net] Sciatica-type pain on one side or both sides, although pain may be wholly absent Weakness of the muscles of the lower legs (often paraplegia) Achilles (ankle) reflex absent[en.wikipedia.org] The patient’s neurological examination essentially is normal, except for absent ankle reflexes.[ahcmedia.com]

  • Lumbosacral Plexus Disorder

    […] patellar reflex L4 Medial lower leg/foot Knee extensors and ankle dorsiflexors Diminished or absent patellar reflex L5 Lateral leg/foot Hallux extension and ankle plantar[physio-pedia.com] Patellar tendon reflex and ankle jerk were absent on the right leg. Sensory function could not be examined properly.[austinpublishinggroup.com] There is an absent or reduced knee jerk reflex, although ankle jerks are commonly preserved.[patient.info]

    Proximal lower limb muscles were affected in 40% patients, rare upper limb involvement and ankle reflexes were absent in all with evidence of axonal degeneration and reinnervation[annalsofian.org] .  Tendon reflexes: Absent or Preserved except at ankles  Recovery: With delay after removal of toxin  Progression ("coasting") for 1 to 4 months  Improvement: Months[slideshare.net] ankle reflexes, and postural tremor with mild motor involvement [93] and generally resolve after removal from exposure although there may be a residual tremor.
