THE EFFECT OF A CXWORX TRAINING ON BALANCE, UPPER LIMB FUNCTION AND LOWER LIMB PROPRIOCEPTION OF ABSOLUTE DEAF ADOLESCENT GIRLS

Children with hearing loss are at risk for vestibular dysfunction and a defect in this part can affect postural stability. Balance control is a dynamic stage that causes the body to remain in a state of stillness and balanced motion, which is controlled by the visual, atrial, and profound systems(۲, ۳). Proprioception is an important part of the sensory input of the sensory-motor system, which is known as conscious perception of the position of limbs in space, and having a good proprioception is one of the most basic factors involved in maintaining balance. This study investigated the effect of a CXWORX training on balance, upper limb function and lower limb proprioception of absolute deaf adolescent girls. This research method was Semi-experimental study with a pre-test and post-test design and its statistical population consisted of ۶۳ completely deaf adolescent girls of Urmia city. Among them, ۳۰ persons based on G-Power method(۵) with mean age (experimental group ۱۹.۰۷ ± ۲.۴ and control group ۱۷.۹۳ ± ۳.۰۶), height (experimental group ۱.۶۸ ± ۰.۰۵ and control group ۱.۷۰ ± ۰.۰۷), weight (experimental group ۵۸.۴۶ ± ۷.۵۱ and control group ۵۹.۷۰ ± ۵.۵۵) were selected. The subjects were divided into control and experimental groups (۱۵ subjects in each group). Y test was used to measure dynamic balance and upper limb function and Kinovea software was used to measure lower limb proprioception. Shapirovilk test was used to evaluate the normality of data distribution and dependent t-test and analysis of covariance were used to analyze the hypotheses. It was done in SPSS software at a significant level of ۰.۰۵. The results of the present study showed that CXWORX exercises improved dynamic balance, upper limb function and lower limb proprioception of absolute deaf adolescent girls (P≤۰.۰۵) in both intra-group and inter-group comparisons. Therefore, this exercise program can be used to achieve various goals, including increasing the proprioception of the ankle and knee by eliminating visual input, and also to increase the upper limbs function and thus improve the performance and balance function in this group of absolute deaf girls.
