• Registration Number: NCT03487757
• Lead Sponsor: Bezmialem Vakif University

Brief Summary

In this study the investigators will examine the effects of core stabilization exercises on respiratory muscle strength, respiratory functions and postural control in hearing-impaired children.

Detailed Description

Hearing organs develop together with the vestibular system and work with close cooperation. Because of this close neuro-anatomic relationship; cochlear, semicircular canal, or both may cause damage to the vestibular dysfunction, resulting in imbalance. Sensory impairment in children with hearing loss may lead to decreased muscle strength and respiratory function with balance and coordination disorders. Core stabilization is provided anatomically with abdominal muscles at the front, spinal and gluteal muscles at the back, diaphragm at the top and pelvic floor and hip muscles at the bottom. Core stabilization training is a training to increase the strength, endurance and neuromuscular control of the aforementioned muscles.

When the literature is checked, the invetigators find that postural control is being evaluated in children with hearing impairment, but there are few studies evaluating respiratory functions. However, they did not encounter a study in which respiratory muscle strength was assessed in these children. In this study the investigators will examine the effects of core stabilization exercises on respiratory muscle strength, respiratory functions and postural control in hearing-impaired children.

Arm && Interventions

Group	Intervention	Description
Control Group	No Intervention	After recording the demographic and clinical information at the beginning of the study and after 8 weeks, respiratory muscle strength, respiratory functions and postural control evaluations will be performed to the children. They won't receive any intervention by this time. At the end of 8 weeks, they may be included in the 8-week physiotherapy program, which will be once a week and 45-60 minutes by supervision of physiotherapist and 4 days a week home exercise program. The program will include core stabilization exercise training.
Training Group	Core Stabilization Exercises	After recording the demographic and clinical information at the beginning of the study, respiratory muscle strength, respiratory functions and postural control evaluations will be performed to the children. They will be included in the 8-week physiotherapy program, which will be once a week and 45-60 minutes by supervision of physiotherapist and 4 days a week home exercise program. The program will include core stabilization exercise training. After the eight week training program the evaluations will be repeated.
