• Hyperreflexia

  OMIM : 58 Spastic paraplegia-12 is an autosomal dominant neurodegenerative disorder characterized by lower limb spasticity and hyperreflexia, resulting in walking difficulties. Some patients may have urinary symptoms and distal sensory impairment. [malacards.org]

  Neurologic examination revealed hyperreflexia and spasticity in the lower extremities, weakness of hip flexion and ankle dorsiflexion, extensor plantar response, diminished vibratory sense in the feet, and pes cavus. [neurology.org]

  People with this condition can also experience exaggerated reflexes (hyperreflexia), ankle spasms, high-arched feet (pes cavus), and reduced bladder control. [ghr.nlm.nih.gov]

  […] spasticity is increased at the hamstrings, quadriceps and ankles  Weakness is most notable at the iliopsoas, tibialis anterior, hamstring muscles  difficulty in walking, decreased vibratory sense at the ankles, and paresthesia  In lower extremities hyperreflexia [slideshare.net]

• Spastic Gait

  The original description of hereditary spastic paraplegia was made by Strümpell in 1880. He described “a pure spastic movement disorder of the legs” in 2 brothers who developed a spastic gait at the ages of 37 and 56 years. [medlink.com]

  Walking pattern described as “spastic gait” occurs in which the following elements are present, each to variable degree in different individuals: a) heel strike is shifted forward (landing on the mid-foot or even further forward on the balls of the feet [rarediseases.org]

  Diagnosis of SPG is established by the following clinical features 1, 2 : Typical clinical symptoms of spastic gait impairment and neurologic findings of spastic weakness, hyperreflexia, typically associated with bilateral extensor plantar responses A [centogene.com]

• Lower Extremity Spasticity

  Neurologic examination revealed hyperreflexia and spasticity in the lower extremities, weakness of hip flexion and ankle dorsiflexion, extensor plantar response, diminished vibratory sense in the feet, and pes cavus. [neurology.org]

  Clinical Features  Symptoms depend on the type of HSP inherited  Main feature >>> progressive spasticity in the lower limbs, due to pyramidal tract dysfunction  In the lower extremities, spasticity is increased at the hamstrings, quadriceps and ankles [slideshare.net]

  […] characterized by progressive, usually severe, lower extremity spasticity and weakness. [flybase.org]

  Different genetic loci for autosomal recessive, autosomal dominant, and x-linked forms of hereditary spastic paraplegia have been identified. Clinically, patients present with slowly progressive distal limb weakness and lower extremity spasticity. [icd10data.com]

  All forms of HSP, complicated and uncomplicated, share the primary symptom of lower-extremity spastic weakness. [invitae.com]

  Babinski sign was negative. Video gait analysis was performed, which showed internal rotation of the hips and feet while walking and running. When walking barefooted she dragged the upper side of her toes, this was more pronounced when running. [omicsonline.org]

Prognosis: predicting symptoms and course of HSP As noted above, there is significant variation in HSP symptoms and their severity. This limits the certainty of making predictions. [rarediseases.org]

Prognosis [ edit ] Although HSP is a progressive condition, the prognosis for individuals with HSP varies greatly. It primarily affects the legs although there can be some upperbody involvement in some individuals. [en.wikipedia.org]

Prognosis This varies widely, but most often HSP is compatible with a normal life expectancy. The rate of progression varies considerably and is influenced by the mode of inheritance. [encyclopedia.com]
