The maintenance of the postural balance is due to a set of reflexes that trigger responses based on visual, vestibular or somatosensory stimuli. the object is to find the correlation between the functional level and the quality of life in neurological problem patients. This study is a correlation study design, which intends correlate the sitting balance and functional performance (in activities of daily living like dressing. Transfers and forward wheeling) within the sample. The entire subject performed the modified functional reach test and the results were observed for correlation with pre-specified functional activities performed by the subjects. In my study I found that the quality of life is much more affected in the patients have sitting balance, this is may be the population of the different country. So we can say that all four domains are significantly different. All four have impact on patients. First domain has more impact on patients.
