Abstract
Background and aim: Loss of balance events has been defined as a primarily contributory risk factor associated with construction workers’ fall injuries. It seems that the anatomical and morphological characteristics of the foot affect the motor fitness of individuals, including balance. So, the purpose of the current study was to the assessment of static and dynamic balance and its relationship with related anthropometric indices in construction worker. Materials and methods: This Descriptive-Analytical study was conducted on 114 construction workers in Qazvin province in 2019-2020. First, the construction workers were asked to complete the demographic questionnaire and the inclusion criteria were determined. Then anthropometric dimensions such as height, sitting height, weight, leg length, foot length, foot surface, ankle width, foot breadth, heel width, ankle circumference, thigh circumference, and hip breadth were measured for each subject. balance of participants was assessed with their open eyes and standing position using a Stabilometer device, Non-instrumental static balance was assessed by the Stork test. Instrumental dynamic balance was measured using a stabilometer and two wooden boards and non-instrumental dynamic balance was measured using a YBT kit in three directions. The obtained data were analyzed using Kolmogorov-Smirnov, Pearson and Spearman correlation, Paired sample t-test, Mann-Whitney U test, multiple nominal logistic regression, and multiple linear regression in SPSS software version 25. Results: Twenty-nine point eight percent of construction workers were in weak and very weak classes in terms of static balance. The Pearson and spearman's correlation coefficient showed a significant relationship between age, weight, and Sway Index of individuals. In addition, multiple linear regression showed that age, weight, and foot surface of construction workers can predict the percentage of the Sway Index from the static balance point among construction workers. The highest average normalized reach distances of YBT were in the anterior direction, and were 92.23 ± 12.43% and 92.28 ± 9.26% for right and left foot, respectively. Both maximal and average normalized composite reach in the YBT in each leg were negatively correlated with leg length and navicular drop and positively correlated with the ratio of sitting height to leg length. Conclusion: The results of the current study indicated that demographic information such as age, anthropometric parameters of weight, and foot surface are effective factors on static balance demographic information such as age, anthropometric parameters of navicular drop, leg length, and foot surface are effective factors on dynamic balance in a healthy construction workers’ community with a normal body mass index.
