Hančová, Jana ; Pospíšilová, Mariana (advisor) ; Geržová, Eliška (referee)
The master's thesis "Lower extremity stabilization function assessment using inertial sensors and functional tests in women's american football players" adresses postural control assessment in terms of functional joint stability using inertial sensors. The theoretical part is devoted to matters of functional joint stability, its control and it provides review of assessment options. Also inertial measurement unit function and application for human motion tracking are discussed. The last chapter covers American football considering the research group in the study. The experimental part is in form of study, which uses inertial sensor-based parameters to evaluate functional joint stability that are placed on four body segments and the results are compared with functional test results. We evaluated one-legged stance and single-leg hop test. One-legged stance, bear position and squat were chosen for the functional tests. Obtained data were also discussed in the context of history of injury in the last two years. Results confirm applicability of inertial measurement units for lower extremity stabilization objectification. We proved correlation of thight, shin and instep time to stabilization (TTS) with one-legged stance score and similarly thight and shin TTS with bear position score.

Brázda, Jan ; Smolíková, Libuše (advisor) ; Pospíšilová, Mariana (referee)
Modern elements used in physiotherapy give us the opportunity to intervention and at first sight remote medical fields, such as phoniatry. This work deals with physiotherapy solutions singer and voice performance while preventing possible regular difficulties which have arisen in the course of his career. The aim was to demonstrate the effect of changes in posture and breathing training with incentive spirometers for various voice parameters. A study was conducted which was attended by total of 13 probands from the conservatory students. The probands were divided into two groups. All underwent examination phoniatrist a physiotherapy student and subsequently got a plan to target group assignments lasting six weeks. After this period, both groups repeated the tests and their results are processed. These results showed us improve flexible range of voice, spirometric parameters FVC and FEV1 compared to the control group.

System Microsoft Kinect in rehabilitation
Trněná, Gabriela ; Pospíšilová, Mariana (advisor) ; Zounková, Irena (referee)
System Microsoft Kinect is a commercial gaming device with a game console Xbox. Kinect monitors moves of a player who is controlling the device only by these moves. This system provides to the player visual biofeedback about the moves in a real time. Mentioned benefits might be useful also for rehabilitation tools. The aim of this thesis is to summarise the available findings concerning the usage of Kinect in rehabilitation. Part of the thesis includes practical research, where we were interested about Kinect's capability to evaluate a position of oblique sitting. This position might be used in home therapy of functional disorders of musculoskeletal system. Accessory to the practical part was to create a programme that would tell user if he performed the exercise correctly through the visual biofeedback. Powered by TCPDF (www.tcpdf.org)

The aspects of ga it stability and its assessment
Mišinová, Klára ; Pospíšilová, Mariana (advisor) ; Zounková, Irena (referee)
The bachelor thesis "The aspects of gait stability and its assessment" summarizes knowledge about influences on the gait pattern especially on its stability. The thesis focuses on the control of gait stability, the relationship between the stability of gait, the spatio-temporal measures of gait and COM movement. The part about assessment of gait stability introduces the dynamical systems theory and describes measures with convergent and predictive validity and measures derived from biomechanics. The experimental part studies the change of gait pattern as the reaction on higher head stability demands realized by walking with a book on the head and the reaction on plantar stimulation. The changes of the gait pattern were evaluated by spatio-temporal measures of gait. The interventions influenced the selection of the optimal strategy of gait stabilization. Some subjects narrowed down their step after stimulation by higher head stability demands. The step width of all subjects decreased in comparison with reference values after accomplishment of both interventions.

The effekct of one training of postural stability in patiens with spinocerebellar ataxia
Filipovičová, Jana ; Pospíšilová, Mariana (advisor) ; Jevič, Filip (referee)
We followed the immediate effect of sensorimotor training on postural stability in patients with spinocerebellar ataxia (SCA). We have tried to explain the possible mechanisms of adaptation to change COP, motor learning and neuroplasticity in the field of neurodegenerative changes in the cerebellum. Research Methods: A total of 10 patients with spinocerebellar ataxia (6 men, 4 women) aged 34-71 years, with an average disease duration of 11.6 years participated in the measurement of postural stability. First, we measured the patients with SCA before and after a 15-minute sensorimotor-training exercise, then this group underwent another day of the same measurement without sensorimotor training. As a second control group of 10 healthy subjects served a similar age, who also underwent sensorimotor training. Then we compared the results of posturographic measurement. Results: In the group of SCA patients, sensorimotor training was found significantly lower values in the monitored parameters LENGTH (t stat = 3,537731 > t krit = 2,262157), VELOCITY (t stat = 3,537731 > t krit = 2,262157) and energy to sustain COP (t stat = 2,715085 > t krit = 2,262157), measured on a foam pad with eyes closed. Measurement without making sensorimotor training produced no significant improvement in the results of monitored...

Slackline as a therapeutic possibility to influence postural stability
Komárková, Klára ; Čakrt, Ondřej (advisor) ; Pospíšilová, Mariana (referee)
Objectives: To summarize knowledge about a control of posture, a balance training and a testing on balance platform. I investigate in experimental part of my thesis if slackline training will affect stabilography and differences in quantitative parameters will be found in a training group or a control group. Hypothesis: A specific slackline training positively affects stability which was measured in posturographic selected tests done by the training group. Methods: We test postural stability in control (10 persons) and training (10 persons) group in selected tests of stability. We used a balance platform for testing. The data were statistically analysed. Results: 4 weeks of intense slackline training result in improvement of postural control. That is support by the data of stabilometric examination. The results were just below statistical significance (p > 0.05). Conclusion: The results testify that slacklining can improve postural control in healthy subjects. The results were on the boundary of statistical significance in our intervention group.

Effect of deep foot massage on postural stability in patients with spinocerebellar ataxia
Hlaváčková, Tereza ; Pospíšilová, Mariana (advisor) ; Čech, Zdeněk (referee)
Introduction: Spinocerebellar ataxia (SCA) is currently defined as a group of diseases with progressive cerebellar syndrome, which manifests distinctively by ataxic stance and gait. In patients with SCA, deterioration of postural control occurs due to changes of pathophysiological degenerative nervous system. Control of postural stability is significantly influenced by somatosensory afferentation of soft tissue of foot. The work objective is to determine the effect of deep foot massage on postural stability in the group of patients and to compare obtained results with experiments without deep foot massage. Methods: Seven patients of the Clinic Rehabilitation at the Faculty Hospital, Prague Motol (average age 51.9 ± 13.9 years, 5 men, and 2 women) with SCA and clinical signs of cerebellar ataxia were participated in this study. All patients were examined using posturography before and after application of deep foot massage. Measurements were conducted on a firm surface, foam pad with open and closed eyes. Length of COP trajectory, COP area and COP velocity were measured. Results: Significantly lower values of the length and COP velocity were found on the foam pad with closed eyes, when the deep foot massage was applied. Experiments without applications of the deep foot massage did not show any...

Swimming as an indicator of normal and altered development of the rat
Vítová, Šárka ; Mareš, Pavel (advisor) ; Pospíšilová, Mariana (referee)
Swimming is an inborn reflex in rats. It represents a complex motor behaviour, which changes significantly throughout the postnatal developmental period. In the current study, development of swimming behaviour was studied using a group of rat pups aged between P5 - P21. A protocol for assessment of swimming in the rat was developed based on literature studies and the results of our own observation on rat swimming. The experiments were conducted using a tank 50x15x30cm, filled with water at 24řC, in which each pup is left for 1 minute or less, if it sinks to the bottom. Swimming was assessed using the following developmental markers: sinking, floating, nose position and swimming movements of the limbs. To study the effect of GABAB receptors ligands on the development of swimming behaviour, three groups of pups aged between P12 - P32 were injected intraperitoneally either physiological solution or 3 mg/kg GABAB receptors antagonist CGP 46381 or 3 mg/kg GABAB receptors agonist baclofen, daily between P7 and P11. Results showed that neither CGP 46381, nor baclofen, alters the development of swimming behaviour compared to a control group. Powered by TCPDF (www.tcpdf.org)

Compensation of the subjective visual vertical in patients after surgery of the vestibular schwannoma
Kmeť, Jan ; Čakrt, Ondřej (advisor) ; Pospíšilová, Mariana (referee)
In patients with the vestibular schwannoma balance disorders are common symptom. Problems can appear before a surgery, because of an oppression of the nerve the afferents from vestibular system of affected side is aborted. But it is often that patients have no problems with balance until the operation. After the operation they have a balance disorder, a vertigo and a change in the perception of the vertical. Thanks to the rest of the afferent systems and the otherside vestibular system it comes to a slowly compensation and to a new setting of the verticality in the central nervous system. This bachelor thesis studies our sense of the verticality and a function of each receptor, which participate in modelation of this sense. In practical part we handle the subjective visual vertical, which is a result of the vestibular function. We also observe progress and velocity of SVV compensation in patients after a removal of the vestibular schwannoma and we compare it with the state before the operation.
