Instantaneous center of rotation shifts in symptomatic anterior cruciate ligament deficient knee jointsSimmonds, Michael John January 1990 (has links)
The purpose of this investigation was to document the influence of the anterior cruciate ligament (ACL) in controlling the dynamic interaction between the femur and tibia. Twenty subjects were initially selected to participate based on the results of arthroscopic and proprioceptive tests which established the presence of a uni-lateral, third degree rupture of the ACL. A spline function established the best fitting curve of the instant center (IC) coordinates obtained throughout the ROM. Displacement variables were extrapolated from joint rotation profiles generated from these coordinates. Abnormal displacement migrations of the IC parameter were demonstrated to occur in extension. Migration displacements evaluated between 30$ sp circ$ and 0$ sp circ$ shifted anteriorly 5.07 $ pm$ 1.86 mm for intact knees and 6.97 $ pm$ 2.06 mm for involved knees. This was determined to be significant at the 0.05 level of confidence and correlated well with clinical findings. Mean migration displacements evaluated in flexion (between 100$ sp circ$ and 70$ sp circ)$ were not found to differ significantly between knee conditions.

The biomechanical risk factors associated with preventing and managing iliotibial band syndrome in runners : a systematic reviewAderem, Jodi 04 1900 (has links)
Thesis (MScPhysio)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Introduction: Iliotibial band syndrome (ITBS), an overuse injury, is the second most common running injury and the main cause of lateral knee pain in runners. Due to the increasing number of runners worldwide there has been an increase in its occurrence. Runners with ITBS typically experience symptoms just after heel strike at approximately 20°-30° of knee flexion (impingement zone) during the stance phase of running. A variety of intrinsic and extrinsic risk factors may be responsible for why some runners are more prone to developing symptoms during the impingement zone as opposed to others. Abnormalities in running biomechanics is an intrinsic risk factor which has been most extensively described in literature but little is known about its exact relationship to ITBS.
Objectives: The purpose of this systematic review was to provide an up to date evidence synthesis of the biomechanical risk factors associated with ITBS. These risk factors may need to be considered in the prevention or management of ITBS in runners. A clinical algorithm is also presented.
Methods: A systematic review with meta-analysis was conducted. An electronic search was performed in PubMed, PEDro, SPORTSDisc and Scopus of literature published up-until May 2014. Cross-sectional and cohort studies were eligible for inclusion if they evaluated the lower limb biomechanics of runners with ITBS or those who went onto developing it. All studies included in the review were methodologically appraised. Evidence was graded according to the level of evidence, consistency of evidence and the clinical impact. Data was described narratively using tables or narrative summaries where appropriate. A meta-analysis was conducted for biomechanical risk factors which were reported in at least two studies, provided that homogeneity in the outcomes and samples were present.
Results: A total of 11 studies were included (1 prospective and 10 cross-sectional). Overall the methodological score of the studies was moderate. Increased peak hip adduction and knee internal rotation during the stance phase may predict the development of ITBS in female runners. These biomechanical risk factors may need to be screened for ITBS prevention, despite the evidence base being limited to a single study. Currently there is no conclusive evidence that any of the biomechanical parameters need to be considered when managing runners with ITBS. Stellenbosch University https://scholar.sun.ac.za

Conclusion: Biomechanical differences may exist between runners with ITBS and those who may develop ITBS compared to healthy runners. Although a large variety of biomechanical risk factors were evaluated, the evidence base for screening or managing these risk factors for runners with ITBS is limited. This is due to a small evidence base, small clinical effect and heterogeneity between study outcomes and findings. Further prospective and cross-sectional research is required to ascertain if abnormalities in running biomechanics may be related to why runners develop ITBS or to ascertain which risk factors may be involved when managing these runners. / AFRIKAANSE OPSOMMING: Inleiding: Iliotibiale-band-sindroom (ITBS), ’n besering vanweë oormatige gebruik, is die tweede algemeenste hardloopbesering en die hoofoorsaak van laterale kniepyn by hardlopers. Namate die getal hardlopers wêreldwyd toeneem, neem die voorkoms van hierdie toestand ook toe. Hardlopers met ITBS ervaar tipies simptome ná die hakslag met die knie ongeveer 20-30° gebuig (die wrywingsone of “impingement zone”) gedurende die staanfase van hardloop. Verskeie intrinsieke en ekstrinsieke risikofaktore kan ’n rol speel in waarom sommige hardlopers meer geneig is as ander om gedurende die wrywingsone simptome te ervaar. Abnormaliteite in hardloopbiomeganika is ’n intrinsieke risikofaktor wat reeds omvattend in die literatuur beskryf is. Tog is weinig bekend oor presies hoe dit met ITBS verband hou.
Oogmerke: Die doel van hierdie stelselmatige ondersoek was om ’n sintese te bied van die jongste bewyse van die biomeganiese risikofaktore van ITBS. Hierdie risikofaktore kan dalk oorweeg word om ITBS by hardlopers te voorkom of te bestuur. ’n Kliniese algoritme word ook aangebied.
Metodes: ’n Stelselmatige ondersoek is met behulp van meta-ontleding onderneem. PubMed, PEDro, SPORTSDisc en Scopus is elektronies deurgesoek vir literatuur wat tot en met Mei 2014 verskyn het. Deursnee en kohortstudies is ingesluit indien dit gehandel het oor die biomeganika in die onderste ledemate van hardlopers wat ITBS het of later ontwikkel het. Alle studies wat deel was van die ondersoek is metodologies geëvalueer. Bewyse is aan die hand van bewysvlak, bewyskonsekwentheid en kliniese impak beoordeel. Data is narratief beskryf met behulp van tabelle of narratiewe opsommings waar dit toepaslik was. ’n Meta-ontleding is onderneem waar biomeganiese risikofaktore in minstens twee studies aangemeld is, mits daar homogeniteit in die uitkomste sowel as die steekproewe was.
Resultate: Altesaam 11 studies is ingesluit (een prospektief en tien deursnee). Die metodologiese telling van die studies was oorwegend gemiddeld. Verhoogde spitsheupadduksie en interne knierotasie gedurende die staanfase kan op die ontwikkeling van ITBS by vrouehardlopers dui. Hierdie biomeganiese risikofaktore kan dalk nagegaan word vir ITBS-voorkoming, al was die bewysbasis beperk tot ’n enkele studie. Daar is tans geen afdoende bewys dat enige van die biomeganiese parameters oorweeg behoort te word in die bestuur van langafstandatlete met ITBS nie. Gevolgtrekking: Daar bestaan dalk biomeganiese verskille tussen hardlopers wat ITBS het of kan ontwikkel en gesonde hardlopers. Hoewel ’n groot verskeidenheid biomeganiese risikofaktore beoordeel is, is die bewysbasis vir die toets of bestuur daarvan by atlete met ITBS beperk. Dít is vanweë die klein hoeveelheid bewyse, die klein kliniese impak, en heterogeniteit tussen studie-uitkomste en bevindinge. Verdere prospektiewe en deursneenavorsing word vereis om te bepaal of abnormaliteite in hardloopbiomeganika ’n rol kan speel in waarom langafstandhardlopers ITBS ontwikkel, of om vas te stel watter risikofaktore ter sprake kan wees in die bestuur van hierdie hardlopers.

The state of current knowledge regarding evidence-based conservative management of iliotibial band syndrome : a systematic reviewHarris, Kelly Jayne 23 July 2014 (has links)
Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, 2013. / Background : It has become practically impossible for practitioners to remain current with clinical developments. Additionally the demand from patients and third party payors for quality evidence is increasing. A systematic review is one manner in which information can be graded, summarised and presented in a succinct format for use by practitioners, patients and third party payors.
Objectives : To identify the current knowledge available on the conservative management of iliotibial band syndrome (ITBS) and to evaluate the scientific and methodological rigor of that knowledge. The systematic review of these studies identified the level and type of evidence that currently exists in the support of conservative management of ITBS and the specific interventions and combinations of interventions currently employed.
Method : A systematic review of ITBS studies was conducted. ITBS studies were identified using key indexing terms (iliotibial band syndrome, treatment, conservative and intervention) on several databases (EBSCOhost, Google Scholar, Metalib, Pubmed, Science Direct and Springerlink), all studies were included up until the date of ethics approval (21st May 2012) . The gathered studies were screened for compliance with the inclusion criteria, and then reviewed by blinded independent reviewers (reviewer criteria included qualification, clinical experience, academic experience, research experience and discipline).
Data collection and analysis : The reviewers rated the methodological rigour of the ITBS studies utilising an appropriate scale (e.g. PEDro Scale). Feedback was collated and analysed for discordance. Studies were then analysed, ranked and followed by a discussion in the context of their clinical outcomes, thus formulating a structured summary of the known clinical data with regards to the clinical management of ITBS.
Results:
The identified citations (4130) were screened and sorted by study type. This resulted in 167 citations that were reviewed by abstract for compliance with the inclusion criteria. A final total of 23 studies meet eligibility criteria. Eight articles reported on a combination of interventions, four discussed biomechanical and causative factors, and the remaining eleven articles investigated individual interventions in the treatment of ITBS. After review and analysis, combination interventions were supported by the strongest level of evidence, thus advocating the use of a combination of interventions in the management of ITBS in providing better clinical outcomes. Moderate evidence favoured the use of customised orthoses, injectable corticosteroids, phonophoresis and addressing biomechanical and causative factors. However, there was moderate evidence against the use of deep tissue frictions, as no improvement was found. This outcome suggests a need for further evidence to advocate the appropriateness of these interventions in clinical care of ITBS. Hip abductor strengthening and stretch therapy were found to have limited evidence. However, no evidence was found to support the application of active release technique, corrective neuromuscular approach, custom dry floatation cushions and talar joint manipulation in the management of ITBS. This latter outcome indicated a need for studies to investigate their appropriateness or inappropriateness in clinical care.
Conclusion : The systematic review of ITBS studies revealed that use of a combination of conservative therapies was found to have the strongest level of evidence, which may indicate its appropriateness in the management of patients suffering from ITBS. Specific combinations of conservative therapies and the use of individual therapies require future research in order to better delineate their contribution to the management of ITBS. Randomised controlled trials are the gold standard for research, as they have the greatest level of methodological quality, and should be used where possible when investigating the efficiency of interventions in the treatment of ITBS. Studies, which were not randomised controlled trials, but adopted the principles of a randomised controlled trial structure, contributed positively towards the methodological rigor of these studies.

The effectiveness of three treatment protocols in the treatment of iliotibial band friction syndromeTurnbull, Grant S. D. January 2010 (has links)
Mini-dissertation submitted in partial compliance with the requirements for the Masters Degree in Technology: Chiropractic, Durban University of Technology, 2010. / Iliotibial Band Friction Syndrome (ITBFS) is an overuse injury induced by friction of the iliotibial
band (ITB) over the lateral epicondyle of the femur (LFE) with secondary inflammation. ITBFS is
a prevalent condition and is the most common cause of lateral knee pain in long distance
runners and cyclists.
There are a significant number of aetiological factors related to ITBFS. As a result of this the
general chiropractic approach to the treatment of ITBFS is multimodal and include interventions
such as joint manipulation, cryotherapy, orthotics, massage, electrical stimulation, acupuncture
type procedures and therapeutic exercise. Dry-needling is an effective therapy in the treatment
of active Myofascial Trigger Points (MFTP’s) that are associated with ITBFS. However, the
available literature suggests that to determine its efficacy, it should be performed in isolation.
The association of sacroiliac joint dysfunction in ITBFS has also been addressed and are
thought to co-exist and perpetuate one another. It is recommended that chiropractors include
pelvic manipulation in their treatment protocol for ITBFS however there is a paucity of literature
showing its effectiveness in the treatment of this condition.
There appears to be a need for further research in the form of randomized controlled clinical
trials with regard to chiropractic specific procedures, performed in isolation, in the treatment of
ITBFS. Therefore this study aimed to add to the literature by assessing the effect of the
sacroiliac joint manipulation and dry needling in the treatment of ITBFS.
Objectives
The study aimed to determine the comparative effectiveness of dry needling alone versus
manipulation alone, as well as a combination of the two interventions in the treatment of ITBFS.
Methods
This study was a randomised, open label trial. 47 participants with ITBFS were divided into
three groups, each group receiving a different intervention i.e.: group one received dry needling
of the active MFTP’s in the Tensor Fascia Lata (TFL) and ITB, group two received sacroiliac
joint manipulation, group three received a combination of the two interventions. Subjective
measurements, in the form of the Numerical Pain Rating Scale-101 (NRS-101), and objective
measurements, in the form of algometer readings in the TFL, ITB and Nobles Compression test
as well as digital inclinometer readings of Modified Obers test, were utilised to determine the
effects of the respective interventions. These measurements were recorded twice, once prior to
commencing the treatment programme. These values were then evaluated to compare the
efficacy of the different treatment interventions. Each participant received four treatments over a
two week period.
Results
There were no statistically significant differences between the three treatment groups as they all
seemed to parallel one another with regards to overall improvement in subjective and objective
measurements (P<0.5). However on closer examination subtle differences between the groups
were noted. An interesting endpoint is that the combination group did not fair the best
throughout the study, which was contrary to the original hypothesis. The groups receiving only
the single intervention appeared to fair marginally better over the combination group. A
secondary endpoint that became evident during the study and on analysis of the data, was that
hip joint instability must also be considered when treating ITBFS when there is concomitant
sacroiliac joint dysfunction.
Conclusion
A decision needs to be made with regard to which intervention best suits the individual at the
time. A combination therapy, which originally was thought to be the best treatment option,
should possibly be reconsidered. Perhaps a single intervention of manipulation or dry needling
should be decided upon. In totality, all intervention proved to be effective in the treatment of
ITBFS.

The role of plain film radiography in the diagnosis and management of knee painDamon, Chantelle Ann January 2012 (has links)
Dissertation submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, 2012. / Background:
Attempts to determine the association between the radiographic and clinical findings of knee
pathology have produced conflicting results. It is also not yet known how knee radiographs
influence the conservative management of patients with knee pain.
Objectives:
1. To determine the association between the clinical and radiographic diagnoses of knee pain.
2. To record the consultation at which a radiograph of the knee was requested by the student
or clinician and the reasons thereof.
3. To record the suspected clinical diagnoses and management of the patients prior to referral
for radiographs of the knee.
4. To determine the number of incidental radiographic findings in the selected radiographs.
5. To determine any change in the clinical diagnoses and management following radiographic
reporting of the selected radiographs.
Method:
Radiographic and clinical data from 1 January 1997 to 31 December 2010 were retrospectively
collected from knee radiographs and corresponding patient files from the archives of the
Chiropractic Day Clinic (CDC). Statistical analysis included the use of percentages, mean,
standard deviation, range and frequency counts for the descriptive objectives. Diagnoses were
categorized into specific groups and to construct two-by-two tables of absence or presence of
radiographic vs. clinical diagnosis for each specific diagnosis to determine the association
indicator variables were used.
Results:
The overall agreement between the clinical and radiographic diagnoses was 85.5%. For
degenerative joint disease there was a 97.8% agreement while in Osgood Schlatter’s disease
the agreement was 100%, and in chondromalacia patella the agreement was 50%. However,
there was no agreement between the clinical and radiographic diagnoses for each of the other
specific conditions. Degenerative changes were the most common radiographic findings. The
iv
majority of the knee radiographs were requested at the initial consultation and as the length of
treatment increased, the frequency of radiograph requests decreased. The most common
reasons for referral for radiographs were to identify degenerative changes (47.5%) and to
assess for unspecified pathology (37.4%). Of the 146 patients in this study, 125 patients did not
have a change in diagnosis after radiographs were obtained which means that 85.6% of the
diagnoses remained the same after radiographic examination. There was a wide range of
treatment modalities utilized in the management of patients with knee pain, including soft tissue
therapy, electrotherapeutic modalities and manual therapy (manipulation and mobilization). The
use of manual therapy increased from 67.8% prior to radiographs being taken to 82.9% after
radiographs were obtained.
Conclusion:
Knee radiographs were over-utilized at the CDC and the findings on radiography did not have
much influence on the diagnosis and the management of the patient presenting with knee pain.
The majority of the clinical diagnoses were degenerative causes of knee pain. / Durban University of Technology Research Fund
