The effects of sacroiliac manipulation on arthrogenic muscle inhibition in the hip musculature in patients with sacroiliac syndrome

Morgan, Beverley January 2005 (has links)
Thesis (M.Tech.: Chiropractic)-Dept. of Chiropractic, Durban Institute of Technology, 2005 97 leaves ; 30 cm / In symptomatic sacroiliac syndrome, nociceptors located within the capsule and ligaments of the sacroiliac joint are said to be activated which in turn act on inhibitory interneurons that synapse with the motor neuron pool of the muscles of that joint (muscles responsible for hip flexion, extension, abduction and adduction fall within the sacroiliac motor neuron pool). These inhibitory interneurons relay information that decreases the recruitment ability of that motor neuron pool. This is termed Arthrogenic muscle inhibition (AMI) and it has been stated that the number of motor units innervating a muscle relates positively to the strength of that muscle and hence may have an effect on the functional ability of that muscle. However, it has been proposed that spinal manipulation activates mechanoreceptors (Wyke receptors) from structures in and around the manipulated joint causing changes in motor neuron excitability through the altered afferent input and thereby causing an increase in motor neuron recruitment and a decrease in AMI. Furthermore, it has been found that sacroiliac joint problems have often been related to reduced or asymmetric range of motion (ROM) of the hip and / or lack of proprioceptive ability in the ipsilateral limb. In light of the above, manipulation has been found to cause a re-establishment of normal muscle tone and joint kinematics, therefore relaxing the muscles in that area and restoring normal ROM of the involved joint. This study presents the results of sacroiliac manipulation on objective hip measures (including peak torques, ROM and proprioception).

The effect of a sacroiliac joint manipulation on hip rotation ranges of motion in patients suffering with chronic sacroiliac syndrome

Bisset, Gregory January 2003 (has links)
Thesis (M.Tech.: Chiropractic)-Dept. of Chiropractic, Durban Institute of Technology, 2003 1 v. (various pagings) / Mechanical low back pain is one of the most common clinical disorders that most people seek help for (Painting et al. 1998:110). Epidemiological studies indicate a lifetime prevalence of low back pain ranging from 60 to 80% with an annual incidence of approximately 30% (Mosheni-Bandepi et al., 1998). The Sacroiliac (S.I.) joint is a significant source of pain in patients with chronic low back pain and it therefore warrants further study (Schwarzer et al. 1995:31). S.I. syndrome is defined as pain over the S.I. joint in the region of the posterior superior iliac spine, which may be accompanied by referred pain over the buttock, greater trochanter, groin, posterior thigh, knee, and occasionally to the postero-lateral calf, ankle and foot (Kirkaldy-Willis, 1992:123). Research indicates that there seems to be a correlation between low back pain, more specifically S.I. pain and hip rotation (Ellison et al. 1990, Cibulka et al. 1999, Fairbank et al. 1984). Cibulka et al. (1998) found that patients with lower back pain who were classified as having signs suggestive of S.I. regional pain had significantly more external rotation than internal rotation on the posterior innominate side i.e. side of S.I. dysfunction (approximately a 20 difference). Manipulation is recognised as an effective means of treating mechanical low back pain, with respect to both Lumbar Facet Joint Syndrome and S.I. Joint Syndrome (Assendelft et al. 1992 and Koes et al. 1996). Kirkaldy- Willis (1992:123) states that manipulation is the most certain way of relieving the symptoms of S.I. syndrome. This investigation aimed to determine the effect of a sacroiliac joint manipulation on hip rotation ranges of motion (active and passive motion) in patients with chronic sacroiliac syndrome in terms of objective measures.

The effectiveness of sacroiliac manipulation alone versus sacroiliac manipulation following ischaemic compression of gluteus medius trigger points in the treatment of sacroiliac syndrome

Thompson, Neil January 2002 (has links)
Thesis (M.Tech.: Chiropractic) -Dept. of Chiropractic, Durban Institute of Technology, 2002 1 v. (various pagings) / In recent years, sacroiliac syndrome has been widely accepted by many different health professions as one of the major contributors to mechanical low back pain. Manipulation to effect the relief of the condition has thus far proven to be one of the most effective methods. However, comparatively little research has been done on the different forms of physical therapy that can be used in conjunction with a manipulation so as to maximise its effect. This study focussed on the use of ischaemic compression (a well-accepted technique for the treatment of myofascial trigger points) of the gluteus medius muscle.

The efficacy of a toggle recoil drop piece adjustment technique in the treatment of sacroiliac dysfunction

Jacobs, Ronel C. January 2005 (has links)
Thesis (M.Tech.: Chiropractic)-Dept. of Chiropractic, Durban Institute of Technology, 2005. xiii, 115 leaves / One of the most common clinical disorders known is mechanical low back pain (Painting et al. 1998:110). A significant source of low back pain is the sacroiliac joint and therefore, according to Schwarzer et al. (1995:31), it warrants further study. With respect to treatment, Gatterman (1995) states that specific manipulative therapy is the treatment of choice for sacroiliac dysfunction. This is supported by clinical studies (Cassidy et al., 1992), which have shown significant improvement with daily manipulation over a 2-3 week period in 90% of the patients suffering from sacroiliac dysfunction. Different adjusting techniques for the sacroiliac joint include side posture adjustment and prone drop piece adjustments (Bergmann, 1993). With respect to side posture, Bergmann (1993) further states that the side posture adjustment is the most common position used. However, it has been noted that side posture can produce unwanted rotation in the lumbar spine. This may be detrimental to patients who have contra-indications to torsioning such as abdominal aortic aneurisms, nerve root entrapment or disc pathology. Patients, who experience anterior catching of the hip capsule or decreased flexibility with side posture adjustments, experience more discomfort and could therefore benefit from a different technique (Gatterman, 1995). Hence the need for an effective adjustment technique that does not rely on torsioning (e.g. drop piece technique). (White, 2003; Pooke, 2003; Hyde, 2003; Pretorius, 2003; Haldeman, 2003; Cramer, 2003; Engelbrecht, 2003). Although drop table thrusting techniques were rated as being effective for the care of patients with neuromuskuloskeletal problems (Haldeman et al., 1993) as cited by Gatterman et al., (2001), it is still unknown which specific drop piece technique is the most appropriate for sacroiliac dysfunction. Therefore this study was aimed at determining the efficacy of a toggle recoil drop piece adjustment technique.

The relative effectiveness of Kinesio® taping methods as an adjunct to a single sacroiliac joint manipulation in the treatment of chronic sacroiliac joint syndrome

De Beer, Quintin Hardus 13 November 2013 (has links)
Dissertation submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, 2013. / The lifetime incidence of low back pain is between 48% to 79% in South Africa. Globally, chronic Sacroiliac Joint Syndrome occurs in 13% to 63% of the world’s population. Therefore, chronic Sacroiliac Joint Syndrome is a significant health problem that has the potential to have a major impact on quality of life. Chronic Sacroiliac Joint Syndrome is described as an alteration in normal motion or mechanics. The Sacroiliac Joint fibrous capsule contributes to proprioceptive and nociceptive output, which may be exacerbated when the joint is in a dysfunctional state. Chronic Sacroiliac Joint Syndrome may be effectively treated by spinal manipulative therapy. Spinal manipulative therapy is professed to have four therapeutic effects – mechanical correction, pain reducing effects, circulatory increase and neurobiologic effects. Similarly, Kinesio Tex® Tape therapy is professed to have comparable therapeutic effects – circulatory increase, pain reduction and stimulation of proprioceptive systems. Spinal manipulative therapy and Kinesio Tex® Tape therapy may, therefore, have similar therapeutic effects which, if used in adjunction, may produce enhanced therapeutic effects and accelerated results regarding reduction of symptoms in patients with chronic Sacroiliac Joint Syndrome. This investigation aimed to determine whether Kinesio ® Taping methods would have any relative effect on the Sacroiliac Joint, and whether it would be appropriate to use as an adjunct to spinal manipulative therapy in the treatment of chronic Sacroiliac Joint Syndrome. The study was a prospective stratified clinical trial with three intervention groups, twenty participants in each (n = 60). All participants were 18-50 years of age and suffering from chronic Sacroiliac Joint Syndrome. Subjective measurements included the Numerical Rating Scale and Oswestry Low Back Pain Disability Index. Objective measurements included the Algometer Scores. Numerical Rating Scale and Algometer measurements were taken before and immediately after treatment at the first consultation and at the second consultation. Oswestry Low Back Pain Disability Index measurements were taken at the first and second consultation. Group One underwent spinal manipulative therapy alone, Group Two underwent Kinesio Tex® Tape therapy alone and Group Three underwent both spinal manipulative therapy and Kinesio Tex® Tape therapy in combination. Comparisons were made using the Unpaired and Paired t-tests. The results for the Inter-group analyses suggested that most comparisons were statistically insignificant (p ≥ 0.05) which indicated that all treatment groups appeared to improve to a similar degree. The results for the Intra-group analyses suggested that most comparisons were statistically significant (p < 0.05) which indicated that Kinesio Tex® Tape therapy was effective as an adjunct to spinal manipulative therapy, however not statistically more or less effective that spinal manipulative therapy or Kinesio Tex® Tape therapy alone. In conclusion, it was found that some differences did occur, however these differences were not sufficient enough to conclude that one treatment was more effective than the other. Further research with a larger sample size, more frequent treatments and follow-ups, a more homogenous stratification of age, ethnic group, gender, side of diagnosis and categorizing participant occupation is needed in order for the power of the study to be amplified and, therefore, any results would carry more weight.

The effects of sacroiliac manipulative therapy versus functional and kinetic treatment with rehabilitation (FAKTR) on improving hamstring flexibility

Gouws, Estelle January 2015 (has links)
M.Tech. (Chiropractic) / Background: In sporting activity, especially rugby, soccer, cricket and hockey, re-occurring hamstring injuries are a common sight that suggests that there is an opening for an improvement in the treatment and management of these injuries. This can be debilitating to any sportsman as it results in recurrent time away from his/her sporting activity. A study by Fyfer, Yelverton and Sher (2005), found that sacroiliac manipulation alone had a positive effect in the treatment of recurrent hamstring injuries. Cibuklka, Rose, Delitto and Sinacore (1986), proposed a possible link between hamstring muscle injuries and sacroiliac joint dysfunction. A study conducted by Donahue, Docherty and Schrader (2010), on the effects of Graston technique on pressure pain threshold, revealed a significant improvement in the patient’s pain threshold due to the fact that the instrument assisted technique effectively broke down scar tissue and correct fascial restrictions. The FAKTR approach to soft tissue dysfunction combines instrument-assisted soft tissue mobilization (Graston Technique) with proprioceptive (functional) techniques to reduce pain and return to function (Hyde and Doerr, 2012). Objective: This blinded, randomised pilot study was done to investigate the effects of sacroiliac joint manipulative therapy versus functional and kinetic treatment with rehabilitation on hamstring flexibility in previously injured hamstring muscle. Design: The study consisted of 30 participants recruited from the University of Johannesburg by word of mouth and posters, which met the inclusion criteria. They were equally and randomly divided into 2 groups. Group 1 received chiropractic therapy of the sacroiliac joint. Group 2 received functional and kinetic treatment with rehabilitation. Objective measurements consisted of digital inclinometer which measured the flexibility and range of motion of the hamstring muscle. The pressure algometry was used to measure pain pressure threshold. Procedure: Both group participants hamstring flexibility and ranges of motion were tested. Group 1 participants were motion palpated to determine sacroiliac joint dysfunction and treated with a high velocity, low amplitude trust to restricted segment, group 2 received functional and kinetic treatment with rehabilitation. Results: The statistical results should be viewed with regards that this study only represent a small group of thirty participants and therefore no assumption can be made with respect to whole population. The p-value was set at 0.05 and represents the level of significance of the results. If the p-value was less or equal to 0.05 (p≤0.05) there was a statistical significance finding. If the p-value is greater than 0.05 (p>0.05) vi there was no statistical finding. Statistical significance only means that a given result is unlikely to have occurred by chance. Analysis included demographic data analysis of age and gender. Objective data were collected using Digital Inclinometer and Pressure Algometry. Intra-group and inter-group analysis was done on straight leg raise, passive knee extension, hip extension, lateral rotation of the hip and medial rotation of the hip. The Shapiro-Wilk test was performed to determine normality. As normality could not be assumed, non-parametric testing were used to do intra-group analysis. The Non-parametric Friedman test was used to determine if a change occurred over time. As change did occur over time the Wilcoxon Signed Rank Test was use to determined where the change within each group occurred. The Mann-Whitney U test was also used to determine if any difference between the groups were present at any given time. At the end of the study both test groups showed significant clinical as well as statistical improvement over the three week course of the study. Conclusion: The FAKTR treatment did clinically have the greatest improvement, however the changes seen was not statistically superior to those seen with the sacroiliac joint manipulation treatment. A statistical significant improvement was seen in both treatment protocols, concluding that both the spinal manipulative therapy and the functional and kinetic treatment with rehabilitation could be proficient protocols in treating hamstring flexibility.

A study to determine the efficacy of chiropractic manipulation combined with Kinesio® taping in the treatment of chronic lower back pain

07 November 2012 (has links)
M.Tech. (Chiropractic) / Chronic lower back pain is a very common condition affecting 60-80% of the worlds’ population at sometime in their lives. Manual therapy, including chiropractic manipulation, has been proven to be very successful in the treatment of chronic lower back pain and reduction in muscle tension. Although chiropractic treatment alone is effective in the treatment of chronic lower back pain, chiropractors often search for adjunctive modalities to enhance the positive outcomes of their treatment. Kinesio® tape application to the lumbar para-spinal muscles has been proven to be effective in increasing lumbar range of motion and in decreasing lower back pain. The purpose of this study was to determine whether the combination of Chiropractic manipulation and Kinesio® taping of the lumbar para-spinals is a more efficient, and possibly effective, treatment protocol in the treatment of chronic lower back pain. Method: This study was a comparative study and consisted of three groups of ten participants. The participants were between the ages of eighteen and forty years of age, with a male to female ration of 1:1. The potential participants were examined and accepted according to the inclusion and exclusion criteria. Group 1 received chiropractic manipulative therapy to the lumbar spine and sacroiliac joints. Group 2 only received the application of Kinesio® tape to the lumbar para-spinal muscles. Group 3 was the combination group, and received chiropractic manipulative therapy to the lumbar spine and sacroiliac joints together with the application of Kinesio® tape to the lumbar para-spinal muscles. Subjective measurements consisted of the Numerical Pain Rating Scale and the Oswestry Pain and Disability Index and objective measurements was range of motion of the lumbar spine. Procedure: Treatment consisted of seven consultations over a three week period. Objective and subjective readings were taken at the beginning of the first, fourth and seventh consultations before treatment. Subjective readings were taken from the Numerical Pain Rating scale and the Oswestry Pain and Disability index.Objective Readings were taken from measurements taken from the Digital Inclinometer device measuring lumbar range of motion. At the first to sixth consultation participants each received their groups’ specific treatment protocol, the seventh consultation consisted of data collection only.

The effect of a sacroiliac joint manipulation on hip rotation ranges of motion in patients suffering with chronic sacroiliac syndrome
