Abstract
Abstract:
Introduction:
Restriction on the range of motion of the ankle and knee joints is one of the most important causes of movement and balance disorders in the lower limbs that can affect and disrupt the Neuromuscular control of the structures around the ankle and knee. Therefore, the research question is whether the limitation in the range of motion of the ankle and knee is related to the level of quality of life of blind people or not?
Materials and Methods:
The present study was correlational. The statistical sample includes 32 blind boys with an average age of 23.93 years, weight of 75.62 kg and height of 169.34 cm, University of Tehran, who were purposefully selected. To evaluate the quality of life, the Persian version of the Health-Related Quality of Life Questionnaire (SF = 36) was used. Lunge and hamstring flexibility (SLR) tests were used to measure the range of motion of the ankle and knee joints, respectively. The normality of the data was used using Shapiro-wilk test and Pearson correlation coefficient test was used to investigate the relationship between the research variables at a significance level of 0.05.

Results:
The results of Pearson correlation test showed that between the total score of quality of life level with Lunge test (ankle movement limit) dominant leg (r = 466, P = 0.007), with hamstring flexibility test (knee mobility limit) dominant leg (R = 0.726, P = 0.001) and non-dominant foot (r = 0.961, P = 0.001) there is a significant relationship (P <0.05). Also, there is no significant relationship between the overall score of quality of life level and non-dominant ankle movement limitation tests (P> 0.05).
Conclusion:
Due to the significant relationship between the range of motion of the lower knee and ankle joints and its effect on the quality of life, the use of stretching exercises and flexibility can be an effective factor on the range of motion of the ankle and knee. Which improves the muscular function of the joints and ultimately leads to an increased quality of life in the blindness.
