he objective of the present study was to assess the isokinetic, cardiovascular and psychophysical responses of young adult males (N=30) during valve turning exercises. It aimed to evaluate the variables in relation to changes in control design and working posture. Isokinetic testing and ergonomics have not been widely linked and it was an aim of this study to show the advantages to the field of ergonomics. Furthermore, the “work-simulation” package used in the present study has not been widely exploited and it was believed that this study could thus contribute significantly to the literature. Testing was carried out using a CYBEX ® 6000 isokinetic dynamometer, a polar heart watch, an Omron M1 semi-automatic blood pressure monitor and various perceptual rating scales. Testing involved the subjects having to perform 4 maximal turning efforts in 18 different conditions. These conditions were made up by using 6 different control designs in 3 varying positions. Subjects were required to attend two sessions, each approximately one hour long, in which nine randomised conditions were tested in each session. During these sessions, isokinetic responses: peak torque (Nm), total work (J) and average power (W); cardiovascular responses: heart rate (bt.min[superscript -1]) and blood pressure (mmHg); and psychophysical responses: RPE and discomfort, were observed. The results of the tests showed that in general significant differences were encountered for isokinetic, cardiovascular and psychophysical responses in relation to changes in the control design. However, significant differences were far less evident, and in most cases non existent, in relation to changes in the spatial orientation of the control types. The essence being that operator position with respect to the control is not as crucial as the control design.

M.Tech. / This study aimed to compare either separately or in combination the effects of chiropractic manipulation and ergonomic advice on cervical and thoracic pain and discomfort in those working at computer workstations or in desk bound professions. Three groups were chosen. Group A was treated with chiropractic manipulation only. Group B received ergonomic advice only, which they were required to adhere to for the duration of the study. Group C received a combination of chiropractic manipulation and ergonomic advice. Subjects within each group were attended to over a period of three weeks. It was anticipated that a combination of the therapies would yield the most favorable results in comparison to either of the therapies alone. The study was a clinical trial involving three groups of ten subjects of women only. Volunteers responded to posters placed throughout the University of Johannesburg, Doornfontein campus and at companies in and around Johannesburg. Objective data was collected using the Cervical Range of Motion (CROM) Instrument and the Digital Inclinometer to measure cervical and thoracic spine range of motion. Subjective data was obtained by participants recording their progress on the Vernon Mior Neck Pain and Disability Index and the Numerical Pain Rating Scale. Both the objective and subjective data was collected prior to the commencement of the first, third and sixth treatments for Groups A and C and at the first, second and third consultations for Group B. All the collected data was statistically analyzed using the One Way and the Repeated Analysis of Variance tests. Data obtained from cervical and thoracic ranges of motion testing showed some significant differences for the three groups throughout the treatment however no consistent pattern was revealed to determine which treatment group was favored. Statistical analysis of the data obtained from the questionnaires indicated that all three groups responded with statistical significance to the treatments. All three groups responded with a reduction in the subject‟s perceived pain and disability and the Combination group responded most favorably followed by the Advice/Ergonomics group and then lastly the Adjustment group. This study concluded that a combination of the therapies resulted in a quicker response to treatment with regards to the subject‟s pain and disability. All of the three treatments however provided some improvement therefore also reiterating the effects of ergonomic advice and chiropractic treatment alone.

M. Tech. / Repetitive Strain Injury (RSI) of the shoulder is a condition that results because of poor posture, stress and a lack of sufficient rest periods between working schedules. This study attempts to demonstrate the effect of the homoeopathically prepared complex remedy Spascupreel® S in the treatment of RSI. Thirty participants were selected for the study and completed the study. The study was conducted over a period of five weeks. Fifteen participants formed part of the control group, and fifteen participants formed part of the experimental group. The control group received placebo (saline solution) injections, and the experimental group received Spascupreel® S injections for the duration of the study. All the participants were assessed by means of questionnaires, algometer readings and physical examinations throughout the study. The results were statistically analysed using the independent-samples t-test, Chi-square test, Mann-Whitney U test, Wilcoxon Signed Rank test, Friedman test and McNemar test. The results showed that treatment with Spascupreel® S indicated a tendency towards statistical significance in improving the symptoms of RSI.

Since a significantly greater percentage of body weight is supported by the non-paretic limb following stroke, a greater amount of fatigue may be present during daily activities. This may affect the ability of these individuals to maintain a stable upright posture. The presence of falls following a stroke has been attributed in part to this asymmetrical stance post-stroke. Therefore the purpose of this study was to assess the effect of quadriceps muscle fatigue on bi-pedal posture in individuals who had a stroke and an age-matched control group. Although individuals after stroke displayed greater postural sway under the paretic limb than the non-paretic limb or control subjects, results of this study show that sustaining an isometric knee extension of the non-paretic limb induces changes in postural control for individuals after stroke, but that these changes do not markedly differ from those of healthy age-matched controls.
