A comparison between chiropractic adjustment and muscle stability exercise programme for chronic low back pain in former ballet and modern dancersKingon, Tarryn Frances 01 August 2012 (has links)
M.Tech. / Purpose: This study aims to compare the effects of chiropractic adjustment to the lumbar spine and/or pelvis, and chiropractic adjustment to the lumbar spine and/or pelvis in conjunction with a muscle stability exercise programme in the treatment of chronic low back pain in former ballet and modern dancers with regards to pain, disability and lumbar spine and pelvic range of motion. These effects were based on a questionnaire consisting of a Numerical Pain Rating Scale, and an Oswestry Low Back Pain and Disability Index, and on lumbar spine range of motion (ROM) readings taken using a digital inclinometer. The questionnaire was completed and the ROM readings taken prior to treatment on the first, fourth and seventh visits. Method: Thirty participants who met the inclusion criteria were randomly allocated to one of two different groups of fifteen participants each. One group received chiropractic adjustments to the lumbar spine and/or sacroiliac joints, with an added muscle stability exercise programme. The second group received chiropractic adjustments to the lumbar spine and/or sacroiliac joints alone. Treatment took place over a period of three weeks, and participants were treated six times out of a total of seven visits. Procedure: Subjective data was collected at the first and fourth consultations prior to treatment, as well as on the seventh consultation by means of a Numerical Pain Rating Scale (NPRS) as well as an Oswestry Low Back Pain and Disability Index to assess pain and disability levels. Objective data was collected at the first and fourth consultations prior to treatment, and at the seventh consultation by means of a digital inclinometer for assessing lumbar spine range of motion (ROM). Data collected was analysed by a statistician. Results: Clinically and statistically significant improvements in group 1 and group 2 were noted over the duration of the study with regards to pain and disability, however the lumbar spine range of motion results were inconsistent with regards to the expected outcome of increased range of motion. Conclusion: The results show that both chiropractic adjustment, as well as chiropractic adjustment in conjunction with a muscle stability exercise programme, are effective treatment protocols both clinically and statistically in decreasing pain and disability in former ballet and modern dancers with chronic low back pain, however, neither treatment protocol proved to be preferential over the other. The results also showed a larger decrease in lumbar spine range of motion than the expected increase in lumbar spine range of motion.

A study to compare the effect of lumbar spine adjustments, rectus femoris muscle stretches and a combination of both treatments on the flexibility of the rectus femoris musclesBoshoff, Anèe 27 March 2012 (has links)
M.Tech. / This unblinded, randomised pilot study was performed to determine and compare the effect of innervation specific lumbar spine adjustments and stretching on the flexibility of the rectus femoris muscles in asymptomatic subjects. Twelve asymptomatic subjects between the ages of 20 and 30 years were recruited by the use of advertisements placed around the University of Johannesburg, Doornfontein Campus. The inclusion criteria required that the patient had decreased rectus femoris muscle flexibility (testing positive on the rectus femoris contracture test) and no history of, or any current osteoarthritis or pathology of the hips or knees. The patients were randomly placed into one of three groups by drawing a group number from a closed bag. Group 1 consisted of four subjects receiving a single lumbar spine adjustment per treatment relating to the most restricted segment in the L2-L4 area as well as bilateral proprioceptive neuromuscular facilitation (PNF) of the rectus femoris muscles; Group 2 consisted of four subjects receiving bilateral rectus femoris muscle stretches (PNF); and Group 3 consisted of four subjects who received a single lumbar spine adjustment at the L2-L4 area to the most restricted segment found. One adjustment per treatment was performed. With the subject in the rectus femoris contracture test position, a goniometer was used to measure the knee range of motion bilaterally before and after treatments. These measurements were used as objective data. Each subject was treated twelve times over a four to six week period. The objective results indicated that there was a statistically significant improvement in rectus femoris muscle flexibility in both Group 1 and Group 3. In conclusion, it was shown that specific adjustments at the spinal level of the nerve innervation for the rectus femoris muscle resulted in an improvement of the flexibility of the rectus femoris muscle and with a greater effect on the leg ipsilateral to the side of the spinal adjustment. This gives support for the effectiveness of innervation specific spinal adjustments.

Flexion distraction in conjunction with diversified lumbar adjustments in the treatment of chronic mechanical low back painMc William, Chase Ross 01 April 2014 (has links)
M.Tech. (Chiropractic) / 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.

The evaluation of normal radiographic measurements of the lumbar spine in young to middle aged Indian females in DurbanNaidoo, Melanee January 2008 (has links)
Thesis (M.Tech.: Chiropractic)-Durban University of Technology, 2008 / To evaluate the lumbar lordosis, lumbosacral angle, lumbosacral disc angle, lumbosacral
lordosis angle, intervertebral disc angles and heights, interpedicular distances, sagittal canal
diameters and the lumbar gravity line (selected radiographic parameters) in young to middle
aged Indian females in Durban.
To determine any association between the selected radiographic parameters and the age of
the subjects, weight, height and body mass index of the subjects, occupation, smoking,
previous pregnancy and leg length inequality (selected anthropometric and demographic
factors).
Methods:
Sixty healthy, asymptomatic, young to middle aged, Indian females were recruited for this
study. All subjects underwent a case history, a physical examination and radiographic
evaluation (AP and lateral views) of the lumbar spine. SPSS version 15.0 (SPSS Inc.,
Chicago, Ill, USA) was used to analyze the data.
Results:
The mean (± SD) of the lumbar lordosis, lumbosacral angle, lumbosacral disc angle and
lumbosacral lordosis angle was 49º (± 6º), 39º (± 8º), 12º (± 5º) and 143.2º (± 5º)
respectively. For the lumbar intervertebral disc angles at L1-L2, L2-L3, L3-L4, L4-L5 and L5-
S1 levels, the mean (± SD) was 6º (± 2º), 8º (± 2º), 10º (± 3º), 12º (± 4º) and 12º (± 5º)
respectively. The anterior and posterior intervertebral disc heights at the respective vertebral
levels were: L1-L2: anterior: 8 mm (± 2), posterior 5 mm (± 2); L2-L3: anterior: 10 mm (± 2),
posterior 5 mm (± 2); L3-L4: anterior: 12 mm (± 2), posterior 5 mm (± 2); L4-L5: anterior: 14
mm (± 3), posterior 5 mm (± 2) and L5-S1: anterior: 13 mm (± 4), posterior 6 mm (± 2). The
mean (± SD) of the interpedicular distance at the L1, L2, L3, L4 and L5 vertebral levels was
23 mm (± 2), 24 mm (± 2), 25 mm (± 2), 27 mm (± 2) and 31 mm (± 3) respectively. For the
sagittal canal diameter at the L1, L2, L3, L4 and L5 vertebral levels, the mean (± SD) was 20
mm (± 5), 21 mm (± 3), 21 mm (± 3), 21 mm (± 3) and 19 mm (± 3) respectively. The lumbar
gravity line intersected the sacrum in 67.3% of the subjects. In 29.1% of the subjects, the
lumbar gravity line passed anterior to the sacrum while in 3.6% of the subjects, it passed
posterior to the sacrum.
iv
A significant association was found between lumbar lordosis and the height of the subjects in
this study (p = 0.004). A decrease in the intervertebral disc height at L5-S1 was associated
with smoking (p = 0.005). A decrease in the intervertebral disc height at L4-L5 was
associated with previous pregnancy (p = 0.016). Body mass index of 26–30 kg.m-2 was
significantly associated with an increase in the intervertebral disc angles at L3-L4 (p = 0.028)
and L4-L5 (p = 0.031). A decrease in the L5-S1 intervertebral disc angle was also
significantly associated with smoking (p = 0.023). There was a significant association
between previous pregnancy and an increase in the intervertebral disc angle at L3-L4 (p =
0.016). A significant association was found between the age of the subjects and the L5-S1
intervertebral disc angle (p = 0.007). Specifically it was the 23–27 year group and 33–37 year
group who were significantly different from each other (p = 0.033).
Conclusion:
Similarities and differences were found in the mean values of the radiographic parameters
measured in this study and those reported in the literature. A number of the selected
anthropometric and demographic factors were associated with some of the lumbar
radiographic parameters. Further studies are required to establish the clinical significance of
these findings.
