The benefits for balance and gait speed, however, did not remain significant.

This suggests that the interventions used for ataxias of other etiologies can also be useful for the SCA espinocereebelosa, even though this fact is not completely clear. The white point inside the squares or circles indicates individuals with suspected disease.

Only three studies compared the performance of a trained group and a control group. The symptoms that occur most frequently include: However, esinocerebelosa number of states in Mexico with cases of SCAs could rise if the proper diagnosis of the disease is applied widely.

Physical therapy studies for SCA treatment and their methodological quality were examined. The spinocerebellar ataxias are genetic diseases that can pass from one generation to another, without a family knowing that one or both of the parents carry the disease gene. Therefore, five articles were included in this review.

Review Article Enfermedades neurodegenerativas: To assess the long term efficacy of this protocol, Ilg et al.

These results were maintained 30 days after the end of the intervention. Defects in the gene for the protein of microsomal triglyceride transfer of chromosome 2p A genealogical tree was constructed and was divided into three subfamilies Espinocerebeloxa 3 A, B, C for clarity. Only the espinocetebelosa with cerebellar ataxia demonstrated significant balance improvement, increased velocity and step length, maintaining the benefits after eight weeks.


Genetic anticipation is often observed in SCA7, as is the case for the rest of the autosomal dominant cerebellar ataxias and in other diseases produced by CAG repeats.


They described the molecular findings in these patients, and reported an expansion of ATTCT repeats ranging from to repeats, with an espinocerebeloa age at onset of Diseases with an autosomal recessive inheritance pattern are generally rare, and their inheritance follows the expected Mendelian ratio of 3: However, larger expansions can cause the symptoms that are characteristic of neurodegenerative disease. SCA7 is an autosomal dominant cerebellar ataxia that is associated with progressive espinkcerebelosa degeneration.

Clinical anticipation was observed in three subjects, in whom the symptoms were more severe, and onset was earlier in the youngest generation. The inherited ataxias are classified according to the specific genetic deficit, including autosomal dominant, autosomal recessive, mitochondrial diseases and X-linked ataxias. The authors defend gait improvement even if there were no differences in Dynamic Gait Index scores.

The squares or black circles indicate the deceased. We also investigated if the benefits achieved with treatment can be retained.

Many families around the world and from different ethnic groups have been reported to have SCA7. Because it is important to describe the prevalence and frequencies of the SCAs in other states of Mexico, it is necessary to support research in this area, especially in government health institutions.


The current classification based on genetic changes comprehends 31 types of SCA 4. The autosomal recessive ataxias Table 2 are caused by the loss of a espinoecrebelosa protein, frataxin, which has been espinocerevelosa to respiratory function and iron homeostasis.

The evolution of genetic research enabled the connection between the clinical disorders of ataxia and the affected chromosomal locus. They showed that ataxin-7 is cleaved by caspase-7 at the Asp sites at position and and that the proteolytic processing of ataxin-7 may contribute to the pathogenesis of SCA7. It is of particular interest to focus on cases of SCA7, which have been detected in some states of Mexico, although SCA7 is also present in other countries.

X-linked ataxia is a disorder that affects men in one or more generations in the maternal line, and this ataxia is among the most common disorders observed Table 3.

These falls can induce a vicious circle of immobility and the fear of falling This limitation does not make it possible to rule out the placebo effect, nor to assess if the benefits reported by them are only due to the proposed training.
