Filter by:The objective of this research is to combine the use of inertial systems with virtual reality in pedalling exercises in a pilot study with subjects with ataxia or hemiparesis. In particular, it is intended to evaluate the validity of the system as a physical training tool for pedalling exercises aimed at providing motivational visual stimuli and biofeedback based on pedalling cadence to improve the exercise experience and promote adherence to the subject's treatment. Primary objectives: - To study the estimation of pedalling cadence performed by the system/platform in subjects with hemiparesis or ataxia.. - To study the usability, credibility and intrinsic motivation characteristics of the platform
Cerebellar ataxia with neuropathy and bilateral areflexia syndrome (CANVAS) is a late onset neurodegenerative disorder with a slowly progressive ataxia. It's genetic causative etiology with an autosomal recessive inheritance has a recent discovery. It is clinically characterized by impaired visually enhanced vestibulo-ocular reflex, although patients commonly present with imbalance as a main concern, associated with sensory complaints. It has been demonstrated that sensory impairment in CANVAS patients is due to degeneration of dorsal root with abnormal sensory nerve conduction. Previously defined diagnostic criteria included cerebellar atrophy on brain MRI, neuronopathy on electrophysiological studies and negative genetic testing for other inherited ataxia syndromes like Friedriech ataxia and spinal cerebellar ataxia (SCA). Peripheral nerve ultrasound is a noninvasive technique, able to identify abnormal peripheral nerves with underlying injuries and specific sonographic characteristics. Pelosi et al established that patients with CANVAS have a smaller nerve cross sectional area (CSA) compared to healthy individuals and/ or axonal neuropathies. The main objective of this study was to obtaine a detailed description of peripheral nerves in consecutive patients with CANVAS syndrome followed in theneurology department of the Universitary Hospital of Nimes (France), using conventional electrophysiology and peripheral nerve ultrasound.
Spinocerebellar ataxia type 3 (SCA3) is one of autosomal dominant hereditary ataxias. Standing imbalance, unsteady gait, dysmetria, fatigue, and depression would occur gradually. There are no effective treatment or palliative methods for patients in the present days. However, low-dose growth hormone, or its downstream product, insulin-like growth factor I (IGF-1), may deter the progress of SCA3 in transgenic mice. The main bioactive constituent among the Chinese medicine WT possesses neuroprotective function against glutamate-induced toxicity, which is one major pathology of SCA3. It promotes neurogenesis, and increases the protein expression of IGF-1 in ischemic brains of rats. Thus, we designed a randomized, double-blind trial for patients with SCA3, if WT is a possible neuroprotective medicine. All the subjects will be recruited from Changhua Christian Hospital. Diagnosis is confirmed by gene test and magnetic resonance image by a neurologist. They will be assigned in random and double blind, prescribed with 3 grams concentrated powder of WT or placebo, twice a day, for 12 weeks. After the washout period of 4 weeks, there will be a crossover of placebo or WT for another 12 weeks. After that, another 4-week rest will be followed by the end of trial. Check items in five check points include: 1. Blood examination (serum IGF-1, Neurofilament light chain, mitochondria copy number, 8_OHdG, delta-Ct), 2.Neurological exam (Scale for the Assessment and Rating of Ataxia), 3. Questionnaires (Modified Fatigue Impact Scale, Epworth Sleepiness Scale), 4. Handgrip strength test (which is correlated to IGF-1 value in elderly), and 5. serum metabolites, . All the data will be disclosed after the end of trial. Paired-T test or Wilcoxon Ranked Sign Test will be operated in SPSS.
To examine range of tissue frataxin (FXN) concentrations, specific ribonucleic acids, other proteins and specialized lipids in the buccal cells, blood, and skin cells of normal healthy volunteers without Friedreich's ataxia (FRDA).
This study investigated the effect of exercise using the Emil Jaques-Dalcroze's method on the postural stability of women over 65 years of age. The study model was based on a randomized controlled trial - parallel group design.
This project aims to analyse eye movements, their alterations and influence in reading performance in patients with acquired CNS diseases and compare them with people of the same age, without neurological or ocular pathology and with normal reading speed and pattern. The exploration is focused on the oculomotor system in patients with CNS diseases, even without involvement of the primary visual pathway, and reveals more involvement than the one obtained by a simple ophthalmological examination.
Medulloblastoma is a rapidly-growing tumor of the cerebellum, this area controls balance, posture and sophisticated motor functions like finer hand movements, speech, and swallowing. With the goal of, complete resection, major complications during tumor removal are usually caused by damage to the brain stem and injury to the lower cranial nerves.It has been reported that those children present Ataxia after resection. So the purpose of this study is to investigate the effectiveness of using a selected dual-task- training program to improve postural stability in those Children.
The primary aim is to show balance training improves DCD individual's ability to compensate for their activity limitations, but does not impact disease progression. The second aim is to demonstrate aerobic exercise improves balance and gait in DCD persons by affecting brain processes and slowing cerebellar atrophy.
Forty children with cerebellar ataxia ranged in age from five to nine years old, they were randomly assigned into two matched control and study groups. The control groups received the selected physical therapy program three times weekly one hour per session while the study group received core stability training for 30 minutes in addition to the selected physical therapy program. Both groups were evaluated by SARA Scale for the Assessment and Rating of Ataxia, Balance Error Scoring Systems scale, Bruininks-Oseretsky test of motor Proficiency 2ed subtest 4 (bilateral coordination), and subtest 7 (upper limb coordination), and HUMAC Balance System before and after two months of intervention.
The primary objective is to test the safety and tolerability of short-term therapy with a nicotinamide adenine dinucleotide (NAD+) precursor (MIB-626) in adults with Friedreich's Ataxia (FA) without overt heart failure and with a left ventricular ejection fraction ≥ 40%. A key secondary objective is to test the effects of MIB-626 on cardiac and skeletal muscle bioenergetics.
