|Parkinson's disease (PD) is a neurodegenerative disorder caused by progressive damage of dopaminergic neurons in the substantia nigra of the basal ganglia, which carries the classic tetrad of the disease: rigidity, resting tremor, bradykinesia and postural instability. Balance deficiency is refractory to treatment based on dopaminergic replacement, but rehabilitation is often shown to improve mobility and prevent falls. This is thought to be due to the complexity of the virtual tasks required within the games that involve cognitive process associated with motor performance. The objective of this study was to analyze the safety, feasibility and effectiveness of balance training through the Nintendo Wii Fit PlusTM performed over unstable surface on balance and gait of patients with PD.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity.The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
