Purpose. The study evaluates the effect of task-oriented sensorimotor exercise on visual feedback control of body position and parameters of static and dynamic balance. Basic procedures. A group of 20 PE students (aged 21.5 ± 1.6 years, height 178.2 ± 10.6 cm, and weight 74.5 ± 11.8 kg) performed task-oriented sensorimotor exercise (20 sets of 60 stimuli with 2 min rest in-between). They had to hit the target randomly appearing in one of the corners of the screen by horizontal shifting of COM in appropriate direction. Response time, distance, and velocity of COP trajectory were registered during standing on unstable spring-supported platform equipped with PC system for feedback monitoring of COM movement. Postural stability was evaluated under both static and dynamic conditions (wobble board). The COP velocity was registered at 100 Hz by means of the posturography system FiTRO Sway Check based on dynamometric platform. Main findings. Mean response time significantly (p ≤ 0.01) decreased from 3100.5 ± 1019.8 ms to 1745.8 ± 584.5 ms. Substantial share of the improvements took place during initial 6 trials. At the same time also mean distance of COP movement significantly (p ≤ 0.05) decreased from 0.767 ± 0.340 m to 0.492 ± 0.190 m within initial 12 trials and then slightly increased up to 0.591 ± 0.247 m. On the other hand, mean COP velocity significantly (p ≤ 0.05) increased from 0.285 ± 0.142 m/s to 0.395 ± 0.182 m/s. However, there were no changes in the COP velocity registered in static (from 12.4 ± 1.8 mm/s to 11.9 ± 1.5 mm/s) and dynamic conditions (from 108.0 ± 22.3 mm/s to 101.3 ± 18.1 mm/s). Conclusions. Task-oriented sensorimotor exercise acutely enhances visual feedback control of body position but not static and dynamic balance.

Introduction: Proper development of postural control in children is connected with the maturation of the central nervous system, development of sensory organisation with appropriate use of proprioceptive, visual, vestibular information as well as reactions and postural strategy which allow the maintenance of balance in changeable environmental conditions. Developmental disturbances in this particular area is reflected in postural disfunctions and the assessment of these disfunctions and disturbances needs referring to normative values of the healthy population of children. Aim: Examination of postural control development in children aged 6–17 years. Material: 127 healthy children were tested (65 girls and 62 boys) aged 6–17 years. Method: Laryngological investigation, medical history interview, audiometry and tympanometry were conducted in all children. In the evaluation of postural control (mCTSIB-modified Clinical Test For The Sensory Interaction On Balance) a computer posturography system was used (Balance Master Neurocom). R esults: Further development of postural control was found in healthy children up to the age of 13 years of age. The development was not linear but showed transient characteristics with a faster development stage between the age of 6–7 and 8–9. Better postural control in girls, particularly the youngest, in comparison with boys was noticed. C onclusions: 1. The values of norm postural control in posturographic test mCTSIB in children aged 6–17 was established. In this test postural control development was completed in children before 13 year and it was not linear. 2. Due to gender differences it seems appropriate to use separate norms in order to evaluate the development of postural control in boys and girls.

Introduction: The ability to Reach quickly to changing external stimuli, to move the body quickly and precisely in any direction and to maintain the centre of gravity above the support base, all contribute to maintaining balance in dynamic conditions. The Limits of Stability Test (LOS) provides information on the state of dynamic equilibrium in a standing position. Aim : Assessment of dynamic postural control in developmental age. Material : 127 healthy children (65 girls and 62 boys) aged 6 – 17years. Methods: All children underwent LOS test (posturograph NeuroCom) with registration of reaction time (RT), movement velocity (MVL), directional control (DCL) , maximum excursion (MXE) and endpoint excursion (EPE). Results: At the age of 6-7 years, not fully developed jumping strategy and visual feedback mechanism in the control of movement were observed. All tested parameters were significantly worse in children aged 6 – 9 years. After this period, a significant improvement in TR and MVL was observed, with no significant changes in subsequent age groups while significant improvement in MXE up to 12 , EPE and DCL up to 13 years of age was noted. No significant gender differences were fund in the LOS test parameters. Conclusions: 1 The LOS test showed significantly lower dynamic balance development in children aged 6 – 7 years. 2 The study showed a significant improvement in all parameters of the LOS test up to 13 years of age, which supports the termination of the function at that time.
