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]
He described “a pure spastic movement disorder of the legs” in 2 brothers who developed a spasticgait at the ages of 37 and 56 years.[medlink.com]
Walking pattern described as “spasticgait” 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 spasticgait impairment and neurologic findings of spastic weakness, hyperreflexia, typically associated with bilateral extensor plantar responses A[centogene.com]
If symptoms begin during the teenage years or later, then spasticgait disturbance usually progresses over many years.[en.wikipedia.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 lowerextremities, spasticity is increased at the hamstrings, quadriceps and ankles[slideshare.net]
Clinically, patients present with slowly progressive distal limb weakness and lowerextremityspasticity. Peripheral sensory neurons may be affected in the later stages of the disease.[icd10data.com]

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]

The identification and molecular characterization of additional HSP genes is key to improve our understanding of the underlying pathophysiology.[grantome.com]
Pathophysiology [ edit ] The major feature of HSP is a length dependent axonal degeneration. [21] These include the crossed and uncrossed corticospinal tracts to the legs and fasciculus gracilis.[en.wikipedia.org]
. - Not having an iron core in the rotor prevents cogging caused by magnetic induction; hence the rotation is smooth, with minimum noise and vibration. - By utilizing rare earth magnet with high magnetic properties together with a rotor in basket configuration[namikisingapore.com.sg]
