Filter by:Exergame training might offer a novel treatment approach even in largely nonambulatory subjects with multisystemic degenerative spinocerebellar ataxia.
The purpose of this research study is to investigate how the brain and motor behavior changes both in individuals with spinocerebellar ataxia and healthy individuals, and to assess whether a therapeutic intervention reduces levels of uncoordinated movement and improves motor function in spinocerebellar ataxia (SCA).
Spinocerebellar ataxia (SCA) is a hereditary disorder with movement incoordination. The ataxia performed low intra-cortical facilitation mainly due to the degenerative cerebellum. Noninvasive sensory stimulations such as peripheral electrical stimulation were reported to modulate the excitability of the motor excitability. Neuromuscular electrical stimulation (NMES) was proposed as a neuromodulation tool for the aberrant motor excitability on the SCA. This study aims to investigate the effect of NMES on the motor excitability in the SCA, and the differentiation on the central or peripheral motor excitability changed by the NMES.
The Cerebellum contains ten percent of the total volume of the brain and receives brain, spinal cord and vestibular sensory input. The organization of vestibular and somato-sensory afferent informations are also reported to be impaired in patients with cerebellum dysfunctions. Ataxia and impaired balance control are common symptoms in individuals with spinocerebellar ataxia (SCA). Previous studies have shown that patient with cerebellar damage are usually agonist and antagonist muscle coordination problem. Past studies also found the regulation of reciprocal Ia inhibition was impaired in patients with spinaocerebellar ataxia. In chronic phase, weakness might be developed due to deconditioned. All deficits mentioned above might lead to a decrease functional ability. Therefore, increasing somato-sensory and vestibular input, normalizing the modulation of recriprocal inhibition, and improve muscle strength might be able to improve the functional abilities of individuals with SCA. Recently, whole body vibration (WBV) has been trained for health groups. Studies showed that WBV training were able to improve muscle strength, balance control, and functional ability. However, there is no evidence showed that whether the whole body vibration training can affect the brain and spinal cord for the regulation of neural circuits. Whether also can affect for maximal voluntary contraction and improve central fatigue. No previous studies that whole body vibration training for SCA. Therefore, the purpose of this research was to investigate the intracortical facilitation and inhibition, reciprocal Ia inhibition, low frequency depression, maximal voluntary contraction, interpolated twitch technique to compare the different between the SCA and health subject. Also to investigate the short term and long term effect of WBV.
This is a preliminary study to determine the safety and efficacy of intravenous immune globulin in treating Spinocerebellar Ataxia. The investigators aim to assess changes in clinical measures of disease severity before and after treatment.
Measuring the various difficulties patients with spinocerebellar ataxias (SCA) report in an accurate manner is important to be able to test any therapy that may be developed. As basic research identifies some therapy of this type, clinicians are planning studies that can either prove or disprove that such treatments actually have an effect. Walking problems and problems with eye movements that can give rise to visual complaints are common in the SCA's. Existing neurological scales such as the "SARA" are based on the usual neurological examination items that can carry a degree of subjective bias. Also the intervals between numbers on such scores often do not carry the same "weight" so that the difference between a score of 1 and 2 may not be equal to difference between 2 and 3. Lastly, such scales done in the clinic setting capture only a brief period of a patient's day. We propose that examination of home based gait monitoring, timed tests of motor function and quantitative measures of visual problems in patients with SCA are more useful in measuring the disability in these patients.
