- Description: Abstract: Subacromial impingement syndrome (SIS) is a condition commonly encountered in overhead athletes. Prolonged participation in overhead sporting activities such as cricket may create postural adaptations and muscle imbalances which could lead to altered scapular and glenohumeral kinematics. Altered scapular and shoulder girdle kinematics may result in narrowing of the acromiohumeral distance (AHD), leading to compression of the soft tissue structures passing inferior to the acromion. The aim of this study was to test the hypothesis that the ultrasound measurement of the AHD, at different angles of humeral abduction, in conjunction with the scapular assistance test (SAT), is able to identify SIS risk resulting from scapular dyskinesis before the clinical manifestation of the disease. A prospective quantitative comparative descriptive approach was utilized to collect data from asymptomatic overhead athletes (cricket players), recruited from the university squads of the North West University (NWU) Potchefstroom Campus. The dominant and non-dominant AHD differences, as well as the change in AHD with and without SAT application over selected humeral abduction angles were determined at baseline (N=47). The cricketers were then divided into an exercise intervention and control group to determine whether the application of SAT has the same effect on the AHD measures as a controlled shoulder stability exercise intervention program. Only 27 (intervention group, n=14 and control group, n=13) of the original 47 participants completed the intervention (six weeks), as well as washout period... , M.Tech. (Radiography)

- Description: Abstract:Purpose: The purpose of this study was to determine the most effective method of pre-event treatment for asymptomatic patients through comparing lumbar spine manipulation, lower extremity manipulation and a combination of both on the effect of explosive power and agility, as a measure of improvement. Method: Thirty asymptomatic athletes of moderate to high activity, indicated by the International Physical Activity Questionnaire (IPAQ) participated in this study. Participants were randomly allocated into three equal groups. Group 1 received lumbar spine and pelvis manipulation. Group 2 received lower limb manipulation only and Group 3 received a combination of lumbar spine, pelvis and lower extremity manipulation. Participants had to meet the inclusion and exclusion criteria to be part of the study. Procedure: The study consisted of six consultations over a three week period, with intervention on every consultation and objective data obtained before and after intervention. The intervention period consisted of motion palpation of the specific groups’ regions and manipulative therapy of the findings in each region. Results: All three groups showed improvements in jump height, jump pressure output and the Illinois test. Group 1 showed an average increase in jump height of 3.26 cm, 2.5 Pa average increase in pressure output and 1.32 seconds average increase for the run of the Illinois test. Group 2 showed an average increase in jump height of 3.10 cm, 1.7 Pa average increase in pressure output and 1.03 second average increase for the run of the Illinois test. Group 3 showed an average increase in jump height of 3.09 cm, 2.8 Pa average increase in pressure output and 1.86 second average increase for the run of the Illinois test. Analysis done on the immediate effect of Chiropractic Manipulative Therapy (CMT) on the hang time during the vertical jump test, displayed an overall statistically significant effect 33 %. Although some effect was achieved, the intervention had no constant improvement on the jump hang time. The minor result was attributed to the small changes in readings. Conclusion: Although results obtained were not statistically significant (p>0.05), it demonstrated from a clinical perspective that interventions caused an improvement in jump height, jump pressure output and the Illinois tests’ time in all three groups. Group 3 showed a greater improvement in every aspect, despite being the group with the least demographical advantage. Group 1 had the second best results...

- Description: M.Tech. (Chiropractic) , Purpose: Movement time is the time it takes an individual to perform an actual task. A faster and better movement can be invaluable in athletes using their upper limb. This study aims to see the immediate effect of a chiropractic adjustment on the segments innervating the upper limb, 05 to Ti spinal levels, to movement time in the upper limb, in athletes. Method: This study was a comparative study and consisted of two groups of fifteen. The participants were between the ages of eighteen and thirty five, with a half male to female ratio. The potential participants were examined and accepted according to the inclusion and exclusion criteria. The method of treatment administered to each participant was determined by group allocation. Group 1 received chiropractic adjustments to the segments innervating upper limb (C5-T1). Group 2 was the control group and did not receive treatment, only a rest period of ten minutes was given in between tests. Objective data findings were based on the above treatment protocols. Procedure: Treatment consisted of six treatment consultations with an additional follow up consultation over a three week period, with two consultations being performed per week interval. Objective data readings were taken at the beginning of the first, fourth and seventh consultations. Objective data was collected by the tapping task test and the movement time evaluator program. Analysis of collected data was performed by a statistician. The chiropractic adjustments used were based on restrictions identified during motion palpation and were applied on all the consultations. Results: Clinically significant results were found in group i, the treatment group. Showing a decrease in overall movement time, especially between visit i and visit 4, but also between visit 4 and visit 7. Group 2, the control group, showed a decrease in movement time before and after visit i, but this was only due to learning effect of performing the test for the second time. No statistical significance was found between visit 1 and visit 4 or visit 4 and visit 7.
