  • 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] The patient’s neurological examination essentially is normal, except for absent ankle reflexes.[ahcmedia.com] Also, there may be decreased anal tone; sexual dysfunction; saddle anesthesia; bilateral leg pain and weakness; and bilateral absence of ankle reflexes.[urmc.rochester.edu]

  • Sciatic Neuropathy

    A person's reflexes may be abnormal, with weak or absent ankle-jerk reflex. Several different tests can be performed to find the cause of sciatic nerve dysfunction.[medlineplus.gov] The left ankle reflex was absent, but the knee jerk and plantar responses were normal. There were no petechiae or ecchymoses over the buttocks.[jamanetwork.com] The ankle reflex is depressed or absent on the involved side. This complete deficit is seen only in severe lesions or late in the course of sciatic neuropathy.[clinicalgate.com]

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]

  • Arsenic-Induced Polyneuropathy

    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.
