Thesis (MScPhysio)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Introduction ACL injuries are among the most serious injuries that professional and amateur sports men and women sustain. More than 120 000 ACL injuries occur annually in the USA alone. The highest incidence of ACL injuries are seen in multi-directional and multi-factorial sports such as soccer, basketball, lacrosse, American football, rugby and Australian rules football. It is hoped that the proposed review will clarify issues relating to the effect of fatigue on knee control, as it will focus on multiple movements found in different sporting codes. By including both studies on healthy adults as well as subjects who have sustained ACL injuries, a clearer picture can be formed on the global effect of fatigue on knee control. Objective The objective of this review was to identify, collate and analyse the current evidence on the effect of fatigue protocols on knee control during functional tasks, such as side-stepping, bilateral jumping/landing and crossover-cutting. Methodology A comprehensive search of electronic databases was conducted between April 2013 and August 2013 (updated in April 2014) for eligible articles for inclusion in the review. Methodological quality was assessed using a modified Downs and Black checklist. Results Ten studies met the eligibility criteria and were included in the review. The included studies reported a wide variety of fatigue protocols. Several different test movements were utilised in the studies. The test movements included cutting movements, drop jumps, stop jumps, vertical jumps, bilateral drop landing and rotational movements. The overall results indicated that fatigue had a negative impact on knee control. There were however studies which reported conflicting results. Gender differences were also highlighted in the results of included studies where it became evident that females tend to be more susceptible to knee injuries due to altered kinematics as a result of fatigue. Conclusion Fatigue generally seems to affect knee control negatively across various fatigue protocols. Future research should investigate using a standardised fatigue protocol to achieve more accurate and consistent results during the different functional activities. / AFRIKAANSE OPSOMMING: Nie beskikbaar

It is possible that the demonstration using videotapes or photographs of movements that will be learned can assist the codification, classification and reorganization of the elements of the task in familiar diagrams and thus facilitate the process of motor rehabilitation. The aim of this study was to analyze the performance in the test of recognition of sequences of functional activities such as water drinking and hair combing presented partially (by photos) and completely (by video) to the patients with encephalic vascular accident . The sample was generated from 12 patients (62 ? 8 years) and 10 healthy subjects (53 ? 5 years), of both sex, divided in two groups for which 5 functional activities were presented partially and completely, in 4 sequences that varied between reached and not reached objectives and correct and incorrect movements, during 24 trials. The test t'Student was applied to verify differences in the recognition time between the groups, and to compare the performance between the tests carried through at 9:00 am and retests at 9:00 am and 4:00 pm. To compare the frequency between the types of reply, the test Qui-square was used. It was verified that the patients presented a greater recognition time and a lower number of correct answers than the healthy subjects, and had better performances in the recognition of the complete sequence than the partial one. Bigger frequency was observed in the reply that the objective and the movement were being presented correctly, however the healthy subjects had soon indicated the correct reply in the first trials. An improvement tendency was observed in the performance, when the stages of tests and retests had been carried through in the same schedule. According to the results, it is suggested that the patients with stroke can better recognize the correct movements of a functional activity when it is presented completely in video form, what can influence the choice of the therapeutical strategy during the process of motor rehabilitation / Durante a reabilita??o motora de pacientes com patologias neurol?gicas, existem muitos fatores que interferem no processo terap?utico. ? poss?vel que a demonstra??o utilizando videoteipes ou fotografias de movimentos a serem aprendidos possa auxiliar a codifica??o, classifica??o e reorganiza??o dos elementos da tarefa em esquemas familiares e assim facilitar o processo de reaprendizagem motora.

O teste t`Student foi aplicado para verificar diferen?as no tempo de resposta entre os grupos e para comparar o desempenho entre os testes realizados ?s 9:00 h e retestes ?s 9:00 e 16:00 h. Para comparar a freq??ncia entre os tipos de resposta utilizou-se o teste de Qui-quadrado. Verificou-se que os pacientes apresentaram maior tempo de reconhecimento e menor n?mero de respostas corretas do que os saud?veis e tiveram melhor desempenho no reconhecimento da seq??ncia completa do que das partes. Maior freq??ncia foi observada para a resposta que o objetivo e o movimento estavam sendo apresentados corretamente, por?m os saud?veis indicaram a resposta correta logo nas primeiras tentativas. Observou-se uma tend?ncia a melhora no desempenho quando as etapas de teste e reteste foram realizadas no mesmo hor?rio. Diante dos resultados encontrados sugere-se que os pacientes com AVE podem reconhecer melhor os movimentos corretos de uma atividade funcional quando ela ? apresentada completa em forma de v?deo, o que pode influenciar a escolha da estrat?gia terap?utica durante o processo de reaprendizagem motora

Il est connu que les personnes ayant une hémiparésie à la suite d’un accident vasculaire cérébral (AVC) présentent une mise en charge (MEC) asymétrique lors de la station debout et lors du passage assis à debout (PAD). Par contre, peu d’études ont quantifié l’évolution de la MEC avec la réadaptation ou la précision avec laquelle ces personnes sont capables de la juger. L’objectif principal de ce projet était d’étudier l’évolution de la répartition et la perception de MEC en position debout et lors du PAD chez des personnes hémiparétiques en réadaptation fonctionnelle intensive (RFI). Un objectif secondaire était d’identifier les facteurs qui caractérisent les personnes hémiparétiques les plus asymétriques et les plus atteintes dans leur perception. Cette étude a été menée auprès de seize participants. Les résultats ont démontré qu’une asymétrie de répartition de l’appui en faveur du côté non parétique est présente dès les premiers mois après l’AVC et qu’elle persiste malgré la RFI. Chez les personnes avec une atteinte sévère de la fonction motrice, la MEC était plus symétrique pour le PAD que la station debout. En termes de perception, les personnes hémiparétiques étaient capables d’identifier le côté sur lequel ils mettaient plus d’appui mais ils avaient tendance à surestimer l’appui sur le côté parétique et donc à se juger moins asymétriques qu’ils ne l’étaient en réalité. Très peu de changements ont été observés lorsque les données au congé étaient comparées aux données à l’entrée dans l’étude. En réponse à l’objectif secondaire, la fonction motrice du membre inférieur parétique évaluée par le Chedoke et la différence de force des extenseurs entre les genoux étaient les facteurs les plus déterminants de l’asymétrie et de la perception de MEC. Les résultats obtenus constituent donc une étape supplémentaire vers la compréhension de la répartition asymétrique et les troubles de perception de MEC lors de la station debout et le PAD chez les personnes hémiparétiques. Il serait intéressant dans le futur d’explorer davantage les facteurs susceptibles d’influencer l’asymétrie et la perception de MEC et d’objectiver la relation de cause à effet entre ces deux variables en plus de préciser l’effet réel de l’asymétrie sur la stabilité posturale. / It is well known that people with hemiparesis after stroke have asymmetric weight bearing (WB) when standing and during sit-to-stand (STS). However, few studies have quantified the evolution of WB with rehabilitation or focused on the accuracy with which hemiparetic individuals are able to perceive their WB. The main purpose of this project was to assess the changes, with rehabilitation, in WB distribution and perception of WB during standing position and STS in hemiparetic individuals. A secondary objective was to identify the factors that characterize the most asymmetric hemiparetic individuals and the most affected in their perception. The study was conducted with sixteen participants. The results showed that asymmetric WB is present in the first months after stroke and persists despite rehabilitation. For individuals who had had severe impairment of motor function, WB was more symmetrical during STS than standing. In terms of WB perception, hemiparetic individuals were able to identify the side on which the loading was higher and they generally overestimated the weight under the paretic side. Overall, data at admission and discharge from the study were not different. Furthermore, the motor function of paretic lower limb evaluated by Chedoke and the strength of knee extensors were the most determinant factors of WB and perception. These results can thus be considered as a further step in order to understand the asymmetrical distribution and the impaired perception of WB. It would be interesting in the future to further explore the factors that may influence the perception and asymmetry of WB in order to identify the relationship between these two variables with a specific focus on the impact of WB asymmetry on the patient’s stability in both tasks.
