    Opis:
    Purpose: The aim of the study was to compare the results of six balance tests collected on AMTI AccuSway Plus ACS force platform between healthy female and male children and adolescents. We also searched for possible correlation of the balance measures with subjects’ age. Methods: 228 healthy 6- to 18-year-old subjects (111 boys and 117 girls) participated in the study. Six balance tests were performed with the use of AMTI AccuSway Plus ACS platform: quiet standing for 30s, maximal voluntary sways of the body in the sagittal plane (anterior-posterior – AP test) for 30 s, and in the frontal plane (left-right – ML test) for 30s. All tests were performed in two conditions: eyes open and eyes closed. Results: During quiet standing with eyes open, most balance measures were lower in girls ( p < 0.05). In AP and ML tests with eyes open, a few balance parameters were different between boys and girls ( p < 0.05). In quiet standing, AP and ML tests with eyes closed, there were no between-gender differences ( p > 0.05). In quiet standing with eyes open and closed most balance parameters were negatively correlated with age ( p < 0.05). Conclusions: Quiet standing postural sway characteristics depended on gender under normal visual conditions and it was similar in boys and girls under visual deprivation conditions. The vision was differently used by females and males in balance tasks. Static postural stability improved with age regardless of visual conditions.

    Opis:
    The aim of this study was to establish the reference values of spatiotemporal parameters, joint angles, ground reaction forces and plantar pressure distribution collected simultaneously on the same measurement path during normal gait in a homogenous group of young, healthy women. Methods: The studied group consisted of 28 healthy women aged 21 years on average. The motion capture system BTS Smart-D, 2 AMTI force platforms and Footscan pedobarographic platform were used in this research. The 14-metre measurement path and the 6-metre distance that examined women had to walk through before entering the measurement area ensured that a natural gait pattern was recorded. Statistical analysis was performed to evaluate differences between right and left lower extremities. Results: The applied method enabled collecting several parameters regarding normal female gait biomechanics such as: spatiotemporal parameters, angle-time characteristics as well as range of motion of pelvis, hip, knee and ankle joints in gait cycle, force-time characteristics and peaks of ground reaction force components in stance phase, peak pressure and time of loading of defined foot regions in stance phase. Conclusions: The results may be used by clinicians, physiotherapists or researchers as a reference in diagnosing gait disorders or evaluating patient’s walking pattern. In recent literature there are some disparities in gait parameters reference values even regarding similar research groups. These differences may arise from distinct method, slower or faster gait, other laboratory environment etc. This should be considered and more than one source of normative values should be checked when searching for reference data.

    Opis:
    This article presents data acquisition system developed for the use primarily in Remotely Piloted Aircraft Systems. The system consists of several modules which independently function as Air Data Computer, Attitude and Heading Reference System and Flight Data Recorder. Each module works independently from other modules and also provides capability of real time data transmission. The system is capable of wireless data transmission via ZigBee wireless data protocol. The research may be considered as important and valuable due to the fact that it describes innovative concept of “wireless sensors” system. These type of systems are currently only beginning to appear in commercial applications and such wireless systems appear to be a future of metrology in RPAS applications. Features of each module are stated in the article. The prototype device has been tested and confirmed to be operationally functional.
