Most of probands had restriction of passive motion to segment in thoracic spine and hypermobility of shoulder. Often was present weakness of...

The aim of this study is to evaluate the effect of dynamic stabilizing strategy on handgrip and pinchgrip strength. Exercise utilized in this study was based on rehabilitative approach called Dynamic Neuromuscular Stabilization (DNS) - a developmental kinesiology approach. The exercise program consisted of four primal developmental positions (3½ month supine position, oblique sitting position with support on forearm, position on all fours, and the "bear" position). A study file consisted of ten females who were instructed in basic scheme of DNS exercise. They were instructed to exercise at home five times weekly for a 6- weeks period. One exercise lesson took about thirty minutes. Both handgrip and pinchgrip strength was measured using the digital dynamometer CITEC CT 3001 recording maximum voluntary isometric contraction (MVIC). Three-pinch grip strength and fist grip strength was measured for both upper extremities. Fist grip strength was measured in three positions of forearm (pronation, supination and neutral position). Overall eight variables (for each extremity, grip form and position of the forearm) measured before and after exercise program were compared using the paired t-test. Significant increase in muscle strength (p<0,05) was identified for all eight variables after a 6 weeks exercise...

Submitted in partial compliance with the requirements fo the Master's Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2017. / Background Competitive swimming, as with most other sports that are participated in at more than a recreational level, involves a substantial amount of training. Training excessively results in the overuse of muscles. The overuse of muscles commonly causes the production of myofascial trigger points (MFTPs) within the overworked muscles. The presence of MFTPs is a condition known as myofascial pain syndrome (MPS). Myofascial trigger points may be active or latent. Either way, they produce a wide range of effects. This study focuses on the effect of reduced muscle strength. Muscle strength is essential to athletes as it determines performance. Swimmers with MFTPs will not perform at their full ability. Dry needling is an effective form of treatment for MFTPs as it produces immediate relief from the effects of MFTPs. There is not enough information on the immediate effects of dry needling on athlete performance. Since dry needling brings about the immediate relief of MFTPs, this study aims to restore a swimmer’s muscle power and hence improvement of their swimming performance post-intervention. Aim The aim of this study was to determine the immediate effect of dry needling common myofascial trigger points (MFTP) found in four muscles of the shoulder girdle on competitive swimmers’ 100m freestyle lap-times. Methods The design was a pre-test post-test quasi-experimental study. Thirty five competitive swimmers between the ages of 16 and 30 years old participated in this study. Each participant underwent one assessment. Participants’ lap-times were taken using a Sportline Econosport Stopwatch. The pre- and post-intervention lap-times were compared to each other using statistical analysis. The intervention for the purpose of the study was trigger point dry needling. Myofascial trigger points were assessed using manual palpation and the Myofascial Diagnostic Scale (MDS). Results The median lap time was slightly longer post intervention (0:01:16.10) than pre-intervention (0:01:16.03), and was highly statistically significant (p=0.001). The results of the study were inconclusive, however, as there were too many confounding variables (for example, fatigue due to repeatedly swimming laps, swimmers of a lower caliber and hence quicker fatigue rate being included in the study)which negated the effect of dry needling and so the poorer performance of the participants post-intervention could not be attributed entirely to the intervention. A small number of participant’s lap-times decreased post-intervention i.e. they performed better post-intervention. These individualswere predominantly sprint-swimmers. Conclusion Dry needling negatively affects immediate lap-time performance. Future studies should reduce the number of variables affecting the study, for example, having a sprinter versus long-distance swimmer group, testing the outcome of dry needling after the swimmer has had sufficient time (for example, a day) to rest post-intervention. / M

Title: Corrected arm hang as a compensatory element in physioterapy Objective: The main objective of this master thesis is to measure and compare the level of engagement of muscles stabilizing the scapula during arm hang and supported exercise. Methods: Our study included nine probands whose measurement results were evaluated quantitatively. The age of probands at the time of measurement was from 18 to 25 years. A condition for inclusion in the investigated group was absence of subjective symptoms, functional impairment, traumatic injury, orthopedic defects or diseases of the upper limb. All probands were active athletes. Biomonitor ME 6000 manufacturer Mega Electronics Ltd. was used for recording the electrical activity of the muscles. The obtained data were processed by the Megawin software. All measurements for the purposes of the study took place in the laboratory of biomechanics FTVS UK. The resulting data were compared intraindividual and interindividual. Results: The results demonstrated that middle and lower portions of m. Trapezius is more active in the corrected arm hang. In contrast, the supported exercise leads to greater activity of m. Serratus anterior and lower activity of upper portion of m. Trapezius. Keywords: arm hang, supported exercise, surface electromyography, stabilization...

Title: Effect of the range of the shoulder joint rotation in volleyball players on the development of functional changes. Objectives: The aim of this thesis is to confirm the presence of the glenohumeral internal rotation deficit in beach volleyball players and to determine whether it affects the development of functional changes of the shoulder joint located in the dominant upper limb. Methods: The thesis was a quantitative study with the character of an experiment. There were 60 active volleyball players aged 18-30 years who were deliberately selected for the purposes of the study. The essence was to ascertain whether GIRD affects the pain in the shoulder joint of volleyball players and whether it was deemed positive for all participants of the study. In order to examine the range of motion, the goniometer in the external and internal rotation according to Janda and Pavla, Janda and Sachse was used, as well as hypermobility tests and a shoulder joint pain questionnaire. The statistical data processing was performed by Microsoft Excel 2010. The sum and average functions were used. Subsequently, graphs and tables were created from the results Results: The established hypotheses were confirmed in two cases. GIRD is determined positive for beach volleyball players. From the results of hypermobility...
