OBJECTIVE: The aim of this study was to determine the effectiveness of a single treatment approach of flexion distraction or diversified lumbar adjustments, compared to the combined treatment of flexion distraction in conjunction with diversified lumbar adjustments.
STUDY DESIGN: A total of 30 participants were used, they all presented with chronic low back pain (LBP) of mechanical origin.
SETTING: University of Johannesburg Chiropractic Clinic, Johannesburg, South Africa.
SUBJECTS: The participants were divided randomly into one of 3 groups: Group 1 was treated with diversified lumbar adjustments. Group 2 was treated with flexion distraction directed at the lumbar spine. Group 3 was treated with a combination of diversified lumbar adjustments and flexion distraction. Each participant was treated 6 times over a 3 week period, with a 7th consultation where subjective and objective measurements were taken with no treatment.
METHODS: Group 1 was adjusted on a chiropractic table in a seated or side lying posture. Group 2 was treated lying prone on the Cox Flexion Distraction Table. Group 3 was treated with a combination of the above treatments. Flexion distraction was applied to all participants in group 2. It was applied over the segments that were found to be restricted during motion palpation. One set of 10 repetitions was performed under distraction in each range of motion (ROM). Mobilisation of the restricted joints was executed until full and complete ROM was detected. To ensure that the participant was comfortable and received the best treatment possible Velcro straps were used to secure them onto the flexion distraction table. Diversified chiropractic adjustments were done on the flexion distraction bed or the chiropractic tables in the University of Johannesburg Chiropractic Day Clinic. Spinous Hook (Pull), Thigh-Transverso-Deltoid, Transverso-Deltoid and Push-Pull Technique were the names of the adjustments used to treat participants in group 1 or group 3.
PROCEDURE: Subjective data was collected using the Oswestry Low Back Pain and Disability Questionnaire (ODQ) and the Numerical Pain Rating Scale (NPRS), which were completed by the participants prior to the 1st and 4th consultations and then again on the 7th consultation. Objective data was collected using the Digital Inclinometer. The ROMs measured were forward flexion, extension, left lateral flexion, right lateral flexion left rotation and right rotation of the lumbar spine. This data was collected by the researcher prior to the 1st and 4th consultations and then again on the 7th consultation.
RESULTS: This study was done to try and establish the most effective approach in the management of chronic mechanical LBP using the different treatment approaches.
When comparing the results obtained from the study it can be seen that all 3 groups were effective at reducing pain levels using the NPRS. There was a significant change that occurred on the 7th consultation when looking at the NPRS values. The statistics were then further analysed and a statistically significant difference was shown to have occurred between groups 1 and 3. This indicates that the chiropractic adjustment used alone, was the best treatment protocol compared to groups 2 and 3.
The ODQ values showed that the treatments for all 3 groups were effective at getting the participants back to normal activities of daily living over the treatment protocol, with no preference between any of the treatment protocols.
Statistically significant changes were found to have occurred in only some ranges of motion of the lumbar spine within certain groups. Clinical improvements regarding ROM were evident in group 1 concerning flexion, left rotation and right rotation. A clinical decrease was found in extension, left and right lateral flexion with group 1. Clinical improvements concerning group 2 were found in extension, left rotation and right rotation. Flexion showed a clinical decrease in ROM values of group 2. Statistically significant improvements were found with left and right lateral flexion in group 2. Group 3 showed positive clinical results with left and right rotation. Flexion and left and right lateral flexion ROM showed decreased values clinically in group in group 3. Extension showed a statistically significant decrease in group 3.
These results indicate that chiropractic adjustments used alone, were the best treatment protocol compared to group 2 and 3 when using the NPRS. The ODQ values showed that there was no preference between either of the treatment protocols with regards to normal activities of daily living.
