About

Children's motor skills and physical performance increase with age due to the development of neuromuscular and cardiorespiratory systems. Sensory impairment seen in children with hearing loss can cause balance and coordination disorders, as well as decreased muscle strength and respiratory functions.

Anatomically, core stabilization is provided by the diaphragm, abdominal, hip, pelvic floor, and gluteal muscles. Training for these muscles is intended to improve strength, endurance, and neuromuscular control. This training can help to improve the control of intra-abdominal pressure, intersegmental control of the spine, and muscular control of trunk movement. It also helps in strengthening the respiratory muscles, especially the main inspiratory muscle, the diaphragm. In this study, the effects of core stabilization training on children with hearing impairments' thoracic mobility, functional ability, and trunk muscle endurance will be examined.

Full description

Children's motor skills and physical performance increase with age due to the development of neuromuscular and cardiorespiratory systems. Children with hearing loss can display impaired balance and coordination, as well as decreased muscle strength and respiratory functions. Thoracic mobility relates to the function of respiratory muscles that help expand and contract the ribcage. Exercise capacity, or functional capacity, refers to the individual's ability to perform submaximal activities that require the pulmonary, cardiovascular, and skeletal muscle systems to work together and be healthy. Chest wall expansion determines lung volume and functional capacity. A study in patients with chronic obstructive pulmonary disease showed that lung function was positively associated with reduced chest wall expansion.

Core stabilization is provided anatomically by the abdominal muscles in the front, the spinal and gluteal muscles in the back, the diaphragm above, and the pelvic floor and hip muscles below. Core (trunk) stabilization training is a training to increase strength, endurance, and neuromuscular control of the muscles mentioned above. Thus, intersegmental control of the spine, control of intra-abdominal pressure, and muscular control of trunk movement can be improved. It is also beneficial for strengthening the respiratory muscles, especially the diaphragm, which is the main inspiratory muscle.

When the literature was examined, no studies were found that evaluated the effects of exercise on thoracic mobility (chest expansion) and functional capacity in hearing-impaired children. Our planned study is important because it is the first study to evaluate both chest expansion and functional capacity in hearing-impaired children and also because it is the first study to show the effect of the core stabilization exercise program on chest expansion and functional capacity in these children.

26 participants in 2 patient groups

Study group

Experimental group

Description:

Isometric exercises of the abdominal muscles in the supine, prone, and squatting positions; isotonic exercises in the supine, prone, squatting, and side-lying positions; isotonic exercises in coordination with the extremity movements in the supine, prone, and crawling positions; and trunk rotation exercises in the sitting position will be performed. The Swiss ball will be used for dynamic exercises. It will include isometric and isotonic exercises of the abdominal muscles. Exercises will start with 3 sets of 20 repetitions, gradually increase in intensity on static and dynamic surfaces, and progress towards difficulty. Each exercise will be performed in coordination with breathing control.Breathing control will be coordinated with every exercise.

Treatment:

Other: Core stabilization training

Control group

No Intervention group

Description:

Since no training will be given to the control group during the study, we consider it ethically necessary to provide the same training to the control group if it proves effective after the study is over.
