  Upper limb involvement is relatively uncommon and usually consists of mild hyperreflexia, which may be present early in the disease. A trace of terminal dysmetria may also be found in the upper limbs, but more florid cerebellar signs are not seen. [jnnp.bmj.com]

  All of them started with symptoms consisting of gait difficulties and weakness in the lower extremities, and their neurologic examination showed an upper motor neuron syndrome predominantly in the lower extremities with weakness, spasticity and hyperreflexia [ajnr.org]

  The essential clinical findings are slowly progressive and often include severe spasticity, hyperreflexia, and weakness in a pyramidal distribution, noticeably in both lower limbs, with extensor plantar responses. [emedicine.medscape.com]

• Abnormal Gait

  Furthermore, among the core symptoms of HSP are also included abnormal gait and difficulty in walking, decreased vibratory sense at the ankles, and paresthesia. [13] Initial symptoms are typically difficulty with balance, stubbing the toe or stumbling [ipfs.io]

  Furthermore, among the core symptoms of HSP are also included abnormal gait and difficulty in walking, decreased vibratory sense at the ankles, and paresthesia.[8] Individuals with HSP can experience extreme fatigue associated with central nervous system [en.wikipedia.org]

Prognosis 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. [ipfs.io]

This distinction is important for genetic counseling of family members and for the patient’s prognosis, in that HSP generally carries a more favorable prognosis. [2] Other components of the differential diagnosis of HSP are similar to those of PLS. [emedicine.medscape.com]

Disorders, the prognosis of which differs significantly from HSP, such as multiple sclerosis and familial motor neuron disease should also be excluded. The necessity for investigations will vary depending on the individual clinical picture. [jnnp.bmj.com]

Epidemiology Worldwide, the prevalence of all hereditary spastic paraplegias combined is estimated to be 2 to 6 in 100,000 people. [15] A Norwegian study of more than 2.5 million people published in March 2009 has found an HSP prevalence rate of 7.4/100,000 [ipfs.io]

Epidemiology The prevalence of HSP varies in different studies. Such variation is probably due to a combination of differing diagnostic criteria, variable epidemiological methodology, and geographical factors. [jnnp.bmj.com]
