Context: Dorsiflexion range of motion (DFROM) is often limited in patients with chronic ankle instability (CAI). Whole-body vibration (WBV) may enhance DFROM by helping to reposition the talus and assisting with talocrural arthrokinematics. Objective: To determine if WBV can enhance DFROM in patients with ankle instability and determine if talar position is affected. Setting: Cohort study. Patients or Other Participants: A total of 25 subjects with CAI (17 women, 8 men; age = 22 ±2.101 years, mass = 72.4 ±17.9 kg, height = 171.2 ± 11.6 cm) participated. Intervention(s): Participants in the WBV group completed a 4-week (12 session) WBV program consisting of 6 sets of 30 s at 35 Hz High amplitude with 30 s rest in between standing on a 30° slant board. Participants in the dorsiflexion (DF) group completed a 4-week program without WBV consisting of 6 sets of 30 s standing on a 30° slant board with 30 s rest in between. Participants in the control (C) group did not receive any intervention. Main Outcome Measure(s): Lateral talus position via radiographic imaging, non-weight-bearing (NWB) DFROM, and weight-bearing (WB) DFROM were assessed preintervention, immediately postintervention, and 24 hours after the final intervention. Results: No significant change was detected in talus position measured by X-ray (F = 1.561; p < .05). NWB DFROM (F = 1.543; p < .05) and WB DFROM (F = .774; p < .05) measurements also did not result in significant changes after the WBV program. Conclusions: Four weeks of WBV treatments did not improve talus position or DFROM in ankle instability subjects.

Thesis (M Sport Sc (Sport Science))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: This study investigated the effect of a coordination-training programme on selected fundamental motor skills of children (ages 9 to 12) who were identified as having motor development delays. The group of participants identified included seven boys and one girl. The study followed an A-B-A reversal design. The intervention was a rhythm-based training programme. The dependent variables were the motor abilities of bilateral coordination, balance and upper-limb coordination, assessed using the BOT-2. The results of an ANOVA for dependent groups indicated a significant improvement in bilateral coordination and no change in balance. The improvement in upper-limb coordination was attributed to a familiarisation or learning effect on the test. A descriptive analysis of each child’s results revealed high variability in the effect of participation in the programme. The results of this study supported the conclusion that a rhythm-based coordination-training programme may help children with coordination problems improve their bilateral coordination, which will have a positive impact on the performance on many fundamental gross motor skills. / AFRIKAANSE OPSOMMING: Hierdie studie het die effek van ‘n koördinasie-inoefeningsprogram op die geselekteerde fundementele motoriese vaardighede van kinders (9-12 jaar) ondersoek wat geïdentifiseer is met vertraagde motoriese ontwikkeling. Die geïdentifiseerde groep deelnemers sluit sewe seuns en een dogter in. Die studie het ‘n A-B-A omgekeerde ontwerp gevolg. Die intervensie was ‘n ritmies-gebaseerde inoefeningsprogram. Die afhanklike veranderlikes was die motoriese vaardighede van bilaterale koördinasie, balans en boonste ledematekoördinasie wat geassesser is deur middel van BOT-2. Die resultate van ‘n ANOVA vir afhanklike groepe dui ‘n beduidende verbetering aan in bilaterale koördinasie en geen verandering in balans nie. Die verbetering in boonste ledemate-koördinasie kan toegeskryf word aan vertroudheid met of leereffek van die toets. ‘n Beskrywende analise van elke kind se resultate het ‘n hoë veranderlikheid aan die lig gebring op die effek van deelname in die program. Die resultate van hierdie studie ondersteun die gevolgtrekking dat ‘n ritmies-gebaseerde koördinasie-inoefeningsprogram kinders met koördinasieprobleme kan help om hulle bilaterale koördinasie te verbeter wat ‘n positiewe impak sal hê op prestasie tydens verskeie fundamentele groot motoriese vaardighede.

The thesis deals with the issue of protection of Prague's main train station as a soft target and it's regular operation, mainly by using evacuation model with emphasis on barrier-free issues. Mapping of the building was conducted by using Decree No. 398/2009 Coll. general technical requirements ensuring the barrier-free usage of buildings and their parts. Adapting the environment to people with reduced mobility is not always axiomatic, especially in terms of evacuation. For the movement of these persons it is necessary to take into account their needs and possibilities in normal traffic and during evacuation. The sociological and psychological aspects of crowd and individuals have also significant impact on evacuation. For identifying critical points of the main train station, it has been used knowledge of local research, knowledge of barrier-free buildings, sociology and psychology, and special simulation tools for modeling the movement of people. It has been found that space can be optimized by detailed analysis of simulation outputs to meet all expected requirements without negative impact on barrier-free domain. Thanks to this, it was possible to achieve a new design, which accomplishes higher safety of people with movement and orientation disabilities, especially during emergency situations in building of main train station Prague.
