Abstract

Research Aim: According to research reports, compared to sighted people, energy consumption in simple activities such as walking is more in blind people. It can be said that the mechanical range is combined with the low level of physical fitness factors such as balance, strength, and besides that, the range is low. The movement of the joints increases their fatigue. The purpose of this research was to compare the effect of fatigue on the balance, strength and range of motion of the lower limbs of congenitally and acquired blind people.

Research method: The statistical sample of this research is a total of ۲۰ blind female students between the ages of ۱۴ and ۱۸, who were selected based on the entry and exit criteria and divided into two groups of ۱۰: congenital blind and acquired blind. First, a fatigue protocol for both The group was considered. Then, immediately after the implementation of the fatigue protocol, Romberg, Sharpendromberg, TUG, and FRT tests were used to measure static and dynamic balance, a hand-held dynamometer was used to measure the strength of the lower limb, and a goniometer was used to measure the range of motion of the lower limb, and the results of the tests It was recorded in two times before and after fatigue.

Findings: The results showed that there was a significant difference between the variables of balance, strength and range of motion of the lower limbs in the two groups of congenital and acquired blindness separately, but comparing the effect of fatigue between the two groups of congenital and acquired blindness, there was no significant difference.

Conclusion: The examination and interpretation of the data from this research showed that there was no difference between the two groups of congenital and acquired blindness after fatigue.

Keywords: Blind people, fatigue, balance, strength, range of motion
