The evaluation of a tennis groundstroke by qualitative examination of functional movement
Vojtěchovská, Karolína ; Oplatková, Lenka (advisor) ; Kolář, Jáchym (referee)
This bachelor's thesis describes the evaluation of the tennis groundstroke and the influence of postural stabilization on the resulting quality of activation of the trunk in the groundstroke. The theoretical part summarises the knowledge of the optimal performance of the forehand, as well as the method of evaluating the forehand. In the practical part of the bachelor's thesis, we qualitatively assessed postural stabilization of players according to the concept of DNS. We followed the process of qualitative movement diagnosis and we performer video analysis of the forehand from the Slow-motion recording. The specific parameters of the tennis groundstroke were objectified by using the program Tracker and Zepp Tennis 2 sensor, which gave us the values of angular displacement of the body segments, the angular velocity of hip and shoulder rotation, and the ball speed, the ball spin and the percentage success rate of impact location in the sweetspot of the racket. We made a table of qualitative movement that takes into account key features of the forehand, depending on each phase of the groundstroke. Then we made a complex evaluation of the player's forehand. We concluded that it is not possible to establish a uniform ideal angular alignment of body segments. It is always necessary to respect the...

Influence of compensatory mechanisms arising from violin playing using the DNS method
Hryzlíková, Eliška ; Oplatková, Lenka (advisor) ; Pelíšková, Pavlína (referee)
This thesis investigates compensatory mechanisms arising from playing the violin. It summarizes the existing literature on the topic of the influence of violin playing on the posture of violinists and proposes a compensatory exercise according to the DNS method. The theoretical part describes the "ideal" position for violin playing, the effect of ergonomic aids, kinesiology of playing, anatomy of the shoulder girdle, and finally the compensatory mechanisms stemming from holding and playing the violin while sitting and connected health problems. The experimental part presents the results of case studies of 8 non-professional violin players aged from 18 to 30 years, evaluation of their posture and musculoskeletal disorders, and the proposed compensatory exercise according to the DNS method. The anamnestic data were obtained through a survey and the health condition of the musculoskeletal system is investigated using a kinesiological examination (inspection and palpation, anthropometric measurements, and specific tests for deep stabilizing system and scapula). Inspection and palpation measurement cannot be objectively measured and therefore the obtained measurements serve only as a relative guide for the evaluation. The greatest muscle load is generally in the areas of cervical spine and shoulder...

The role of optical function and its influence to the posture
Terčová, Simona ; Oplatková, Lenka (advisor) ; Veselý, Viktor (referee)
This bachelor thesis deals with the optical function as one of the multisensory modalities in postural control. The theoretical part concerns the anatomy, physiology and pathophysiology of the visual system and their relationship to postural functions. It also includes a further indefinite weakening of neurophysiological principles, influencing other sensory perceptions and motor manifestations with the visually impaired, who belong to group with reduced postural control. The work describes the examination methods and training options for visual perception and its impact on postural control. These applications are applied in the practical sections in the case report of visually impaired patients, in whom the influence of the individual examination unit on postural function was investigated. For the assessment were used the Rehawalk pressure platform and the clinical test of dynamic postural stability Star-Excoursion Balance Test.

Utilization of biofeedback sensors for the activation of breathing and postural function of diaphragm in patients with chronic low-back pain
Macigová, Lucie ; Oplatková, Lenka (advisor) ; Bitnar, Petr (referee)
This thesis is focusing on objectifying the postural function of diaphragm with a biofeedback sensor in patients with low back pain (LBP). The theoretical part provides an overview of known facts about the postural function of the abdominal muscles and diaphragm and the connection between their activation and the change in intra-abdominal pressure and the origin of LBP. The thesis gives specifics of LBP, its etiology and possible methods of classification of non-specific LBP, as well as the methods of evaluating subjective disability. Other methods of objectifying postural functions other than the one used in this thesis are mentioned briefly. Methodology: In the experimental part, we used a capacitive force sensor to test 31 patients with non-specific chronic LBP (aver. age 25.25, SD ± 4.66, aver. height 176.77 cm, SD ± 9.97, aver. weight 77.93 kg, SD ±18.40) in 3 posturally different seated scenarios - resting breathing, with added external load when the subjects held a dumbbell of 20 % of their body weight) and with maximum voluntary increase in intra-abdominal pressure (the diaphragm test). The sensor position was on lumbar triangle and in the groin area. Oswestry Questionaire v2.1a was used to evaluate subjective disability. Results: An independent t-test analysis showes increase in the...

Kinematic analysis of patients with femoroacetabular impingement syndrom
Dinda, Ondřej ; Valouchová, Petra (advisor) ; Oplatková, Lenka (referee)
Bibliographic identification DINDA, Ondřej. Kinematic analysis of patients wiht femoroacetabular impingement syndrome. Prague: Charles University, 2nd Faculty of medicine, Department of Rehabilitation and Sports Medicine, 2017. 82 pages. Supervisor: Mgr. Petra Valouchová, Ph.D. Abstract The purpose of this master thesis was to find out, if there are objective changes in biomechanics of the gait and upstairs gait by objectives with diagnosed femoroacetabular impingement syndrome and by healthy objectives. The data were acquired using kinematic analysis Qualisys and processed using software Qualisys track manager and Visual3D. The subject of research was the range of motion in hip joint in frontal and sagittal plane, than the movement of pelvis in frontal plane, movement of pelvis against thorax in transversal plane and deviation of the axis of spine in frontal plane. These parameters were documented using angular deviation of the segments, deviation of the segments in the plane or shifting of the markers in coordinate system. The conclusions were than statistically evaluated. There were 20 objects with diagnosed femoroacetabular impingement syndrome in the age from 23 to 47 years of age included in the study. In the gait research, a significant difference in angular deviation of the pelvis against thorax in...

Locomat and its use in patients with the spinal cord injuries
Krulík, Jan ; Oplatková, Lenka (advisor) ; Spáčilová, L. (referee)
The improve of the care of patients attend with coming of modern technologies and developments of the medicine science. Concrete instance is Lokomat System, that have risen by multidisciplinary cooperation of a specialists from technical and medical branches. In this thesis will be in detail described not only Lokomat but also advantages and disadvantages of its use to patients and medical personnel. Powered by TCPDF (www.tcpdf.org)
