Os animais foram distribuídos em cinco grupos, cada grupo foi composto por quatro cavalos. O grupo controle não recebeu óleo e os demais foram suplementados com 6, 12, 18 e 24% de óleo. Os animais foram submetidos a sete semanas consecutivas de exercício em esteira rolante e trilha. Analisou-se a influência do treinamento e da suplementação com óleo sobre o peso e escore corporal, concentração de glicogênio muscular e características das fibras do músculo glúteo médio. Os resultados demonstraram que as diferentes concentrações de óleo na dieta não influenciaram as variáveis estudadas. Houve redução significativa do peso corpóreo após o treinamento, no entanto o escore corporal permaneceu constante. O músculo glúteo médio expressou três tipos de fibras puras: I, IIA, IIX. O treinamento não induziu hipertrofia das fibras do músculo glúteo médio. O treinamento ocasionou aumento na proporção e na área relativa das fibras tipo IIA em detrimento das fibras IIX, melhorando a capacidade oxidativa muscular. Tanto as dietas com óleo como o treinamento não aumentaram as concentrações de glicogênio muscular. / The aim of this study was evaluate the effects of supplementation with different concentrations of soy oil and endurance training on gluteus medius muscle adaptations in twenty Arabian horses. The horses were randomized in five groups (four horses each group). The control group did not receive the oil and the other groups were supplemented with 6%, 12%, 18% and 24% of soy oil. The animals were submitted to seven weeks of exercise on treadmill and track. The influence of training and oil supplementation on body weight, corporal score, muscular glycogen stores and characteristics of the gluteus medius muscular fibers were analyzed. The results showed that the supplementation of soy oil in diet was not significantly effective on the studied parameters. There was a significant reduction of the body weight after the end of training; however the corporal score showed no changes. The gluteus medius muscle expressed three types of pure fibers: I, IIA and IIX. The training induced a increase in the proportion and relative area of the type IIA fibers in detriment of type IIX fibers, improving the oxidative capacity muscular. No hypertrophy of the muscular fibers was observed. There were no significant changes in the values of the total glycogen after the training period.

M.Tech. / The aim of this study was to compare the effectiveness of two different treatment methods for myofascial pain and dysfunction syndrome of the Gluteus Medius muscle. This was done in order to determine whether or not a combined treatment of the integrated neuromuscular inhibition technique (INIT) and sacroiliac joint (SIJ) adjustive therapy was more effective than the INIT applied in isolation, in the treatment of the Gluteus Medius myofascial pain and dysfunction syndrome (GMMPDS). Participants were recruited using advertisement posters placed throughout the University of Johannesburg Doornfontein Campus and were treated at the University of Johannesburg Chiropractic Day Clinic. Thirty participants, between the ages of eighteen and fifty years, who were suffering from lower back pain and presented with Gluteus Medius myofascial trigger points (TrPs) and an SIJ dysfunction were selected for the study. They were randomly assigned into one of two groups, consisting of fifteen subjects each, as they entered into the study. Group one received the INIT to the affected Gluteus Medius muscle. Group two received a combination of the INIT to the affected Gluteus Medius muscle and an SIJ adjustment. Patients attended four sessions over a period of eight days and were treated on all of these sessions. Subjective and objective data were recorded on all sessions. Subjective data was recorded using the McGill Pain Questionnaire and the Numerical Pain Rating Scale. Objective data was recorded using the Universal Goniometer, to measure hip ranges of motion of the affected Gluteus Medius muscle, and the Wagner Pressure Algometer to measure pain-pressure threshold of the affected Gluteus Medius muscle TrPs. All of the data were statistically analyzed using Repeated Measures and Independent t-Tests. P-values were calculated to determine the statistical significance of the data. The results of the study indicate that both treatment methods are effective in treating GMMPDS, however a combined treatment approach of INIT and SIJ adjustive therapy was more effective in achieving a greater therapeutic response compared to INIT alone.

M.Tech. (Chiropractic) / Myofascial trigger points (MTrP’s) cause acute discomfort to intense pain and often lead to the use of pain medication as well as loss of man hours (Simons, Travell and Simons, 1999a; Tough, White, Cummings, Richards and Campbell, 2009). Dry needling is very effective and is widely used for the treatment of MTrP’s (Vulfsons, Ratmansky and Kalichman, 2012), but comes with various significant drawbacks, such as the experience of pain during or after treatment (post-needling soreness) or individuals with needle phobias (Unruh, Strong and Wright, 2002). More serious risks also exist, including damage to the viscera (Dommerholt and Fernández-de-las-Peñas, 2013). Low level laser therapy (LLLT) is a non-invasive technique and very little discomfort or pain is experienced by the patient during and after treatment. LLLT is effective in the short- and long-term relief of trigger points and myofascial pain syndrome. Therefore it can easily serve as an alternative to myofacial dry needling (Chow and Barnsley, 2005). This study aimed to determine whether LLLT or myofascial dry needling is more effective in the treatment of active MTrP’s, specifically those of the gluteus medius muscle. It also aimed to determine if LLLT could serve as an alternative treatment to dry needling in cases where dry needling is contraindicated or not desired. Thirty participants who complied with the inclusion criteria were divided into one of two groups. Group 1 (n=15) received dosages of LLLT directly to the active MTrP’s in the gluteus medius muscle and Group 2 (n=15) received myofascial dry needling to active MTrP’s in the gluteus medius muscle. Each participant attended 6 treatment sessions over a course of 2 weeks as well as a 7th measurements-only session.

M.Tech. / The aim of this research study was to determine the most effective way of treating sacroiliac joint dysfunction with associated gluteus medius trigger points, using adjusting of the sacroiliac joint or needling of the gluteus medius muscle or both. The participants were recruited randomly and placed in 3 different groups. Participants in group 1 were treated with an adjustment of the sacroiliac joint, as well as needling of the most prominent gluteus medius trigger point. Participants in group 2 were adjusted only and participants in group 3 were needled only. The treatment of the participants took place at the University of Johannesburg’s chiropractic day clinic. The objective data was acquired using a Digital Inclinometer to measure the ranges of motion at the spinal levels of the 5th lumbar vertebra and the first sacral vertebra (L5/ S1). An Algometer was used to measure the amount of pressure required to evoke pain, within the most prominent trigger point being treated. The subjective data was acquired using the Oswestry Pain and Disability Questionnaire, as well as the Numerical Pain Rating Scale. The results of the trial were of no statistical significance, but clinical improvement in both objective and subjective data was found. Group 2’s mean value percentage improvement was the greatest, when looking at range of motion. Group 1’s mean value percentage improvement was the greatest, with the Algometer and the subjective readings. The outcome of this study was that overall all three treatment protocols had a positive effect on the participants. Group 1 and group 2 had a slightly greater overall improvement. Thus it is suggested that when treating sacroiliac joint dysfunction with associated gluteus medius trigger points, the doctor can use an adjustment or adjusting with needling, both are effective. It is important to take the patients preference into account in order to make them feel at ease with the treatment they are receiving.

M.Tech. / This study aimed to determine the difference between the standard dry needling technique versus the rapid dry needling technique with regards to which technique would provide quicker relief of symptoms, as measured by an increase in participant’s pressure tolerance and range of motion and a decrease in subjective pain. Subjectively it was seen that both groups had a statistical decrease in the participants perceived pain with the Oswestry Disability Index, the McGill’s Pain Questionnaire and the Numeral Pain Rating Scale. Both groups showed significant changes over the two time variables (pre-Treatment one and post-Treatment four) with regards to all the questionnaires. Group 2 showed the most significant change when comparing the two groups with regards to the Oswestry Disability Index and the Numeral Pain Rating Scale. From these results it is seen that subjectively all the participants felt relief with respect to their perceived pain. However, objectively the rapid dry needling technique proved to improve pain faster and more consistently throughout the treatment period over the standard intra-muscular dry needling technique. Therefore the rapid dry needling technique is more effective in treating active Gluteus medius muscle trigger points.

Bakgrund: Trochanterrelaterad smärta anses bero på en bursit eller tendinopati i musklerna gluteus medius eller minimus. Smärtan uppstår när gluteal muskulatur pressas samman mot trochanter major av tractus iliotibialis när höften förs i en adduktion. Konservativ behandling är den primära behandlingsformen. Syfte: Syftet med studien var att genomföra en litteraturöversikt av aktuell litteratur (från 2018 och framåt) som undersökte konservativ behandling vid trochanterrelaterad smärta. Denna studie riktade in sig på interventionerna träning, inflammationsdämpande kortisoninjektion och stötvågsbehandling.Metod: Litteratursökningen genomfördes primärt i två elektroniska databaser: PubMed och Cochrane Library och kompletterades med sökningar i Google sholar samt skolans bibliotek. Sökorden togs fram via MeSH-termer (Medical Subject Headings) från Karolinska Institutet samt fritext. Sju studier mötte inklusionskriterierna och kvalitetsgranskades enligt en utvald mall för randomiserade studier. Evidensgradering utfördes på varje enskild originalstudie enligt en evidensmall. Resultat: Samtliga behandlingsformer; träning, kortisoninjektion och stötvågsbehandling, har visat på signifikanta skillnader i minskad smärta mellan grupperna utvärderat med NRS (Numeric rating scale) eller VAS (Visuell analog skala) och kortisoninjektioner och stötvågsbehandling har även visat på signifikanta minskningar i smärta inom grupperna. VISA-G (Victorian Institute of Sport Assessment – gluteal) uppvisar två signifikanta skillnader i ökad funktion i vardagen och ökad effektstorlek där träning och stötvågsbehandling har högre värde jämfört med kortisoninjektion. En signifikant skillnad i ökad livskvalitet ses hos deltagare som fått stötvågsbehandling. Evidensstyrkan uppmättes till måttligt stark. Konklusion: En oklarhet råder kring vilken behandlingsmetod som har den mest effektiva behandlingsstrategin. Forskningen visar på att en intervention, oavsett om den är aktiv eller placebo, är mer fördelaktig för personer med trochanterrelaterad smärta jämfört med vila.

Master of Science / Department of Animal Sciences and Industry / Michael E. Dikeman / The longissimus lumborum (LL) muscle from 117 steers and the LL, gluteus medius (GM), and triceps brachii (TB) from 132 heifers were obtained to evaluate the effects of feeding zilpaterol hydrochloride (Zilmax®; ZH) (7.56g/907kg on a 100% DM basis) on tenderness. Both genders were blocked by initial weight into 6 blocks of 4 pens. Pens were assigned to treatments of either 0, 20, 30 or 40 d on ZH, with a 3 d withdrawal. One steak was removed from each muscle for proximate analysis and three 2.54 cm thick steaks were vacuum aged for either 7, 14 or 21 d. Steaks were cooked to 70 ˚C and six 1.27 cm diameter cores were removed for Warner-Bratzler shear force (WBSF) determinations. All muscles from steers and heifers fed 30 and 40 d with ZH, had higher (P < 0.05) WBSF compared with controls. The WBSF of steer LL and heifer TB from the 20 d treatment was higher (P < 0.05) than controls. There were no treatment by aging interactions (P > 0.05) for WBSF of steaks from steer LL, heifer LL or heifer TB, but there was a treatment by aging interaction (P < 0.05) for WBSF of steaks from heifer GM. There were no differences (P > 0.05) in percent intramuscular fat for any muscle due to treatment. When using percent intramuscular fat as a covariate, differences in WBSF of steer LL and heifer TB were not altered, but there were slight differences in heifer LL and GM WBSF due to treatment when compared with not using percent fat as a covariate. Percentages of steaks with WBSF ≥ 5 kg increased as days on ZH increased and decreased as days of aging increased. Warner-Bratzler shear force values among the three aging times for steer LL control, 20 and 40 d treatments; all heifer LL treatments, and heifer TB 20 d were all positively correlated (P < 0.01) with each other. Feeding ZH for 20 d generally increased WBSF values, but means were still acceptable. Feeding ZH for 40 d was very detrimental to tenderness.

Dissertation submitted in partial compliance with the requirements for the Masters Degree in Technology: Chiropractic, Durban University of Technology, 2011. / Background: Myofascial pain is a disorder, characterized by the presence of trigger points (MTrP). It is recognised by unique features which include a tender point in a taut band of muscle, a local twitch response (LTR), a characteristic referred pain pattern, and the reproduction of the patient’s usual pain upon examination. A debate exists as to the precise diagnostic criteria used in identifying trigger points. This has hampered the standardized assessment and treatment of Myofascial Pain Syndrome and has led to contradictory findings being reported by various authors due to the lack of a reliable diagnostic tool. Objectives: The first objective was to determine the inter-examiner reliability of palpation of MTrPs in the trapezius and gluteus medius muscles. The second objective was to determine whether training and standardization in palpation techniques would improve inter-examiner reliability of palpation of MTrPs. Methods: This study was designed as a quantitative pre and post intervention interexaminer reliability study. Three examiners (one qualified Chiropractor, one senior chiropractic intern from the CDC and the researcher) were used to examine sixty patients (thirty symptomatic and thirty asymptomatic) for MTrPs. This study was conducted in two phases. During the myofascial examination of patients examiners were required to determine whether a MTrP was present or absent, differentiate whether the MTrP was active or latent and determine the presence or absence of the five characteristics of MTrP (tender point in a taut band of muscle, a local twitch response (LTR), a pain characteristic referred pain pattern, the reproduction of the patient’s usual pain and a jump sign) however, in phase one the researchers were blinded to the characteristics being investigated. Subsequent to phase one, examiners had to attend two, one hour discussion sessions to reduce individual variation in the application of palpation techniques. Results: Inter-examiner reliability was assessed using Fleiss Kappa statistic, percentage agreement and confidence intervals. The results show that three examiners are able to attain acceptable agreement in the palpation of MTrPs, since the features (described above) were shown to improve considerably in phase two after the training session in which standardization of techniques was emphasized. Conclusion: This study provides preliminary evidence that MTrP palpation is reliable and therefore, useful diagnostic tool in the identification of MTrPs and the diagnosis of Myofascial Pain Syndrome.
