Lower Extremity Spasticity
  • Spastic paraplegias are a diverse group of disorders in which the autosomal dominant forms are characterized by progressive, lower extremity spasticity caused by axonal degeneration in the terminal portions of the longest descending and ascending corticospinal[genecards.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]
  • All forms of HSP, complicated and uncomplicated, share the primary symptom of lower-extremity spastic weakness.[invitae.com]
  • “Complicated” HSP is the diagnosis given to an individual who suffers with lower extremity spasticity along with such neurological problems as peripheral neuropathy, seizures, ataxia, optic neuropathy, retinopathy, dementia, mental retardation, and deafness[medschool.lsuhsc.edu]

  • Given these findings, along with prior negative workup, a neurology consult was obtained, and the patient was diagnosed with HSAN. The blisters were unroofed, and local wound care resulted in ultimate improvement of these lesions ( Figure 2 ).[avensonline.org]
  • Our findings confirm that this is indeed not an uncommon presentation of this disorder and we suggest that SPG7 gene analysis should be included in the diagnostic workup of autosomal recessive PEO, especially if spasticity is present.[journals.plos.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]
  • The disease has a fairly good prognosis, but the prominent weakness and spasticity may cause disability later in life. [6] In CMT-5 patients, NCV studies, usually, show a homogeneous reduction in NCV in the common peroneal nerve. [7] , [8] Our patient[sudanmedicalmonitor.org]
  • As there is a continual increase in WES-generated data on genetic variants, the pool of modifier genes likewise grows and diagnostic inferences will become more accurate, thus providing the grounds for a more precise prognosis.[wjgnet.com]
  • 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]
