HSP clinical syndromes may be limited to difficultywalking due to lower extremity spastic weakness (“uncomplicated HSP”) or may include other neurologic or systemic disturbances (“complicated HSP”).[mhmedical.com]
An early feature is difficultywalking due to spasticity and weakness, which typically affect both legs equally.[ghr.nlm.nih.gov]
The primary symptom of HSP is difficultywalking due to weakness and tightness (spasticity) in the legs. Both legs are affected, usually to a relatively similar degree. The term “paraplegia” means severe weakness in both legs including paralysis.[rarediseases.org]

One caveat however: although early childhood-onset forms of HSP may be “non-progressive”, the degree of spasticity may increase slowly if adequate range-of-motion is not maintained through stretching exercises and musclespasticity reduction.[rarediseases.org]
To date, treatment of HSPs is primarily directed symptomatically towards reducing musclespasticity.[els.net]
Treatment for HSP is presently limited to symptomatic reduction of musclespasticity, reduction in urinary urgency, and strength and gait improvement through physical therapy.[link.springer.com]

Neither ankle nor knee clonus was observed. He had no involuntary movements, rigidity or bradykinesia. Truncal and limb ataxia appeared exacerbated. He showed a marked staggering and could not walk without holding on to something.[nature.com]
There was no voluntary movement of either leg, spontaneous clonus was present, planter responses were extensor bilaterally, and sensation was normal. His feet had pes cavus deformity.[jnnp.bmj.com]

HSP clinical syndromes may be limited to difficulty walking due to lowerextremityspastic weakness (“uncomplicated HSP”) or may include other neurologic or systemic disturbances (“complicated HSP”).[mhmedical.com]
Diagnosis HSP is diagnosed by the following: 1) typical symptoms (lowerextremityspastic weakness that may be non-worsening (early childhood onset) or slowly progressive over many years; 2) findings on neurologic examination (lower extremity hyperreflexia[rarediseases.org]
Pure HSPs are characterized by slowly progressive lowerextremityspasticity and weakness, corticospinal tract signs, variable hypertonic urinary disturbances, and mild reduction of lower extremity vibration sense and proprioception.[ng.neurology.org]
Given that both of these disorders are treatable, dopa-responsive dystonia should be excluded in a child with progressive gait disturbance and lower-extremityspasticity of unknown etiology, whereas arginase deficiency should be considered in a young[emedicine.medscape.com]
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]

Standard Therapies Treatment: management of symptoms Despite encouraging progress in many research laboratories (see reference 7 for example), treatment for HSP is presently limited to reducing symptoms of muscle weakness, spasticity, and urinary urgency[rarediseases.org]
Treatment [ edit ] No specific treatment is known that would prevent, slow, or reverse HSP. Available therapies mainly consist of symptomatic medical management and promoting physical and emotional well-being.[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]

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]
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]
[…] inversely correlated with quality of life in a previous study. 31 As the majority of patients in our cohort who met the clinical criteria for HSP did not have a genetic diagnosis, this illustrates the need for studies of clinical parameters which influence prognosis[ng.neurology.org]
