Investigations of the Influence the Sleep Disorders on Postural Stability in Young Men

Lack of sleep is a factor that disrupts the receptors' reception of information from the environ-ment and contributes to the emergence of problems with maintaining balance. The main pur-pose of this study was to find out whether Computer Dynamic Posturography could be a useful tool in distinguishing between people who sleep well from people with insomnia. The study participants were 76 male students who were divided into groups based on the results obtained from the Pittsburgh Sleep Quality Questionnaire. In each group, postural stability had been tested using three main tests: Strategy Organization Test SOT, Motor Control Test MCT and Ad-aptation Test ADT. The results of the analysis show that the obtained results differ in the exam-ined groups under the SOT test. Among people with insomnia, higher values of the tested pa-rameters were noted, than with people who sleep well, which translates into a worse ability to maintain balance. The greatest impact is observed when using eyesight and a vestibular system to maintain a stable posture. It was confirmed that Computer Dynamic Posturography is used to differentiate between people who sleep well from people with insomnia in the group of men. Lack of sleep significantly disturbs postural stability.
