Dissertation submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, 2007. / The aim of this research was to investigate the relative effectiveness of manipulation versus core rehabilitation in the treatment of acute mechanical low back pain in sedentary patients. Recent research has found that dysfunction of the primary core stabiliser muscles is linked with an increasing number of the general population suffering from low back pain; this is thought to be due to the fact that people in general are living more sedentary lifestyles. The Aims and Objectives of this study were to determine the relative effect of manipulation and core rehabilitation in sedentary patients suffering from acute mechanical low back pain in terms of subjective findings, objective findings and to determine any correlations between these findings Thirty-two participants, with acute low back pain participated in the study. They received treatment over a period of three weeks, two treatments in the first week, two treatments in the second week and a follow up seven days later. Group A received a spinal manipulation while Group B received core rehabilitation exercises. Readings were taken at three time points, namely visit one, three and five before the treatment, they included the following readings: Numerical Pain Rating Scale, Algometer, Roland Morris Low Back Pain and Disability Questionnaire, Biofeedback Stabiliser and the Surface EMG. The results showed that there was no differential (p<0.05) treatment effect between the two Groups, and that both Groups showed a clinical improvement in their low back pain. In conclusion, it appears that even though both these treatment protocols have very different mechanisms of action, both can be effective treatment protocols and that core rehabilitation exercises when properly performed are as effective as manipulation in the treatment of acute low back pain.

The purpose of the present study was to assess the pressure distribution responses to three hour seating bouts in a standard car seat condition compared to a Comfort Motion Technology (CMT) car seat condition. Twelve males participated in the study. Subjects came in for two separate sessions no more than one week apart. Pressure distribution on the backrest and seat pan was assessed in a three hour seating bout. Pressure variables associated with increased seating comfort were collected across six distinct 28 minute cycles and then averaged across these six cycles. The pressure variables were contact area, peak contact pressure, and force. The CMT car seat condition exhibited greater back contact area (p= .003) and less back peak pressure (p= .003) than the standard car seat condition. In addition, the CMT car seat condition had greater seat peak pressure (p< .001) and greater back force (p< .001) than the standard car seat condition. In conclusion, the CMT car seat condition is more comfortable than the standard car seat condition. / School of Physical Education, Sport, and Exercise Science

Office chairs are becoming a modern status symbol in the workplace. Many individuals are seated on office chairs for most of the working day. As a result of using poorly designed chairs injury and discomfort are frequently experienced, most particularly lower back pain. Correct design of chairs is imperative, and must be user-centered. The aim of this investigation has been to gather anthropometric dimensions characteristic of the South African population, as this information has not been widely assimilated to date. Once collated, this information could be used in the design of an ergonomically correct office chair, suitable for the unique characteristics of the South African working population. Anthropometric dimensions were collected from 683 South Africans (comprising 448 South African females and 235 South African males) from pre-selected companies in major centres in South Africa (Johannesburg, Pietermaritzburg, Durban, East London, Grahamstown, Port Elizabeth and Cape Town). Measurements included participants’ personal information (age, sex, home language and ethnic group), basic anthropometric measures (stature, shoulder height, mass, and waist and hip circumference) as well as specific measures of fit of the individual to the specially designed, adjustable chair. Of the 448 females, 317 were Black females, 77 were White females, 35 were Coloured females and 19 were Indian/Asian females. Of the 235 males, 112 were Black males, 79 were White males, 26 were Coloured males and 18 were Indian/Asian males. Office chair dimensions for each ethnic group were represented and differences were noted. A comparison between a current office chair’s dimensions and the South African sample office chair’s dimensions indicated modifications that would need to be constructed to suit the South African sample. The conventional office chair is still the most widely accepted office chair due to its stability and support structures that maintain the correct sitting posture of the user. An ergonomic office chair needs to incorporate anthropometric dimensions worldwide.
