The Comparison of Static Balance in Covid-19 Recovered Patients and Healthy Individuals

This study aimed to compare the static balance between healthy individuals and those affected by covid-19, considering the effect of this disease on the central nervous system and the related neurological disorders, as well as the effect of the central nervous system on balance. this descriptive and comparative study was conducted on healthy individuals and those with a history of covid-19 aged 20-40 years in hamedan, iran. the statistical sample of this research included 60 people infected with corona virus from hamadan city, whose balance was evaluated one month and three months after recovery (experimental group) and also 30 healthy people were selected as control group. balance indicators (anterior-posterior and medial-lateral) were examined in eight static positions: double legs stance, single-leg stance with eyes open, and eyes closed conditions, as well as a tandem stance with eyes open and closed by removing visual inputs using a kistler force plate. the results of the analysis of variance showed that there is a significant difference between the control group and the corona group in the sway and the range of cop in one and three months after recovery (p<0.05). the average scores in the control group were lower than one month after recovery and three months after recovery. also, three months after recovery, the average deviations, fluctuations, and range of changes in the foot pressure center were higher than in the control group. according to these results, the balance in people with corona virus approaches the condition of the control group three months after the symptoms disappear, but there are still significant differences in some variables.
