Knowledge, attitudes and beliefs on contributing factors among low back pain patients attending outpatient physiotherapy treatment in Malawi

BACKGROUND: Low back pain (LBP) affects many people globally. Its aetiology is not clear. Patients lack knowledge of its contributing factors and have negative perception about their LBP. This study aimed to identify knowledge, attitudes and beliefs regarding the perceived contributing factors to LBP among patients attending physiotherapy outpatient departments in Malawi. This information can possibly facilitate planning of a LBP education programme in Malawi. METHODS: A quantitative cross-sectional survey was conducted, using a six-part selfadministered questionnaire with questions on demographic information, participants’ attitudes and beliefs regarding their LBP, knowledge about the course and causes of LBP, beliefs regarding nine contributing factors to LBP (identified in a Delphi study) and the sources of the participants’ knowledge. Data were analysed descriptively using the Statistical Package for Social Sciences (version 19.0). A Chi-square test was used to determine any association between variables (alpha 0.05). All ethical procedures were strictly followed. RESULTS: Most participants (186, 91.2 %) did not manage to answer all six questions regarding knowledge correctly and were regarded as ‘partially knowledgeable’ about the course and causes of LBP. More than half (67%) portrayed negative attitudes and beliefs about LBP in general. The findings also showed a statistically significant relationship between knowledge, attitudes and beliefs (p = 0.04). CONCLUSION: This study highlighted that many patients with LBP in Malawi are not adequately knowledgeable about LBP and hold negative attitudes and beliefs regarding their LBP. Therefore, LBP management programmes in Malawi should include education programmes aimed at empowering patients with knowledge regarding LBP, as well as changing their negative attitudes and beliefs about their pain. Patients’ understanding of the cause and nature of their pain may enhance the achievement of treatment goals.DHE

Does the South African physiotherapy journal fulfill the needs of its constituency? a retrospective article review

Professional journals are used to disseminate the knowledge of scholars in the profession and to provide clinicians with guidance for best practice. This article aimed to retrospectively review the role of the South African Journal of Physiotherapy and its contribution to the profession. An archival research design was used to collect information from the archives of the South African Society of Physiotherapy website. The information was retrieved using a data capture sheet and descriptive statistics were used throughout to establish frequencies for the relevant information. During the identified period, 170 articles were published. The greatest number of papers originated in South Africa (81%), 8% from the rest of Africa and 11% written by international authors. Authors with a Masters degree contributed almost 50% of the papers and those with doctorates were responsible for at least 25% of the papers. Most of the papers presented original research (81%) with secondary research such as reviews and scholarly papers accounting for 19% of the total. The most common speciality area addressed through research was linked to musculoskeletal conditions. The journal appears to have provided an important platform for South African academics and emerging researchers to publish their findings. It is suggested that the journal should give preference to papers that deal with issues that are unique to South Africa and sub-Saharan Africa, as these are the least likely to be published elsewhere. In addition, the journal should emphasise papers that will advance the profession.Department of HE and Training approved lis

Accuracy of clinical neurological examination in diagnosing lumbo-sacral radiculopathy: a systematic literature review

BACKGROUND: Lumbar radiculopathy remains a clinical challenge among primary care clinicians in both assessment and diagnosis. This often leads to misdiagnosis and inappropriate treatment of patients resulting in poor health outcomes, exacerbating this already debilitating condition. This review evaluated 12 primary diagnostic accuracy studies that specifically assessed the performance of various individual and grouped clinical neurological tests in detecting nerve root impingement, as established in the current literature. METHODS: Eight electronic data bases were searched for relevant articles from inception until July 2016. All primary diagnostic studies which investigated the accuracy of clinical neurological test (s) in diagnosing lumbar radiculopathy among patients with low back and referred leg symptoms were screened for inclusion. Qualifying studies were retrieved and independently assessed for methodological quality using the ‘Quality Assessment of Diagnostic tests Accuracy Studies’ criteria. RESULTS: A total of 12 studies which investigated standard components of clinical neurological examination of (sensory, motor, tendon reflex and neuro-dynamics) of the lumbo-sacral spine were included. The mean inter-observer agreement on quality assessment by two independent reviewers was fair (k = 0.3 – 0.7). The diagnostic performance of sensory testing using MR imaging as a reference standard demonstrated a sensitivity (confidence interval 95%) 0.61 (0.47-0.73) and a specificity of 0.63 (0.38-0.84). Motor tests sensitivity was poor to moderate, ranging from 0.13 (0.04-0.31) to 0.61 (0.36-0.83). Generally, the diagnostic performance of reflex testing was notably good with specificity ranging from (confidence interval 95%) 0.60 (0.51-0.69) to 0.93 (0.87-0.97) and sensitivity ranging from 0.14 (0.09-0.21) to 0.67 (0.21-0.94). Femoral nerve stretch test had a high sensitivity of (confidence interval 95%) 1.00 (0.40-1.00) and specificity of 0.83 (0.52-0.98) while SLR test recorded a mean sensitivity of 0.84 (0.72-0.92) and specificity of 0.78 (0.67-0.87). CONCLUSION: There is a scarcity of studies on the diagnostic accuracy of clinical neurological examination testing. Furthermore there seem to be a disconnect among researchers regarding the diagnostic utility of lower limb neurodynamic tests which include the Straight Leg Raise and Femoral Nerve tests for sciatic and femoral nerve respectively. Whether these tests are able to detect the presence of disc herniation and subsequent nerve root compression or hyper-sensitivity of the sacral and femoral plexus due to mechanical irritation still remains debatable.IS

Comparison of Terminology in Patient Education Booklets for Lumbar Surgery

Abstract Purpose: To compare the usage of 'provocative' terms in two patient education booklets for lumbar surgery. Background: The recently completed FASTER trial failed to support the use of an evidence-based educational booklet to significantly improve postsurgical outcomes over rehabilitation and usual care. The use of a different booklet in another recently completed trial resulted in a significant saving in healthcare utilization; earlier return to work; and greater patient satisfaction with surgery. We propose that the terminology used in these booklets may account for the differing results. Methods: An expert review panel was identified and tasked with identifying and highlight 'provocative' words within two patient educational booklets -Booklet A 'Your Back Operation' and Booklet B'Your Nerves are Having Back Surgery'. Reviewers were blinded to title and authorship of the booklets. Data Analysis: Descriptive statistics including means, total scores. Results: Seventeenreviewers from 7 different countries participated and found that Booklet A had almost 3 times as many provocative terms as Booklet B. Booklet A had an average of 67.2 provocative terms per reviewer compared to only 22.6 terms for Booklet B. Conclusions: The findings of this study suggest that use of an educational booklet that minimizes the use of provocative terminology may have the potential to decrease fear, anxiety and patient pain experiences following lumbar surgery. Further research is warranted

Accuracy of magnetic resonance imaging in detecting lumbo-sacral nerve root compromise: A systematic literature review

Background: MRI is considered to be the diagnostic tool of choice in diagnosing nerve root compromise among patients presenting with clinical suspicion of lumbo-sacral radiculopathy. There exists controversy among researchers and clinicians regarding the diagnostic utility and accuracy of MRI in detecting nerve root compromise and radiculopathy. This review evaluated 4 primary diagnostic accuracy studies that specifically assessed the accuracy of MRI in detecting nerve root compromise, as established in the current literature. Methods: Eight electronic data bases were searched for relevant articles from inception until January 2014. All primary diagnostic studies which investigated the accuracy of MRI in diagnosing nerve root compromise among patients with low back and referred leg symptoms were screened for inclusion. Qualifying studies were retrieved and independently assessed for methodological quality using the 'Quality Assessment of Diagnostic tests Accuracy Studies' criteria. Results: Four studies qualified for inclusion in this review. The sensitivity of MRI in detecting lumbar nerve root compromise was very low at 0.25 (95 % CI) while the specificity was relatively high at 0.92 (95 % CI). Conclusions: There is lack of sufficient high quality scientific evidence in support or against the use of MRI in diagnosing nerve root compression and radiculopathy. Therefore, clinicians should always correlate the findings of MRI with the patients' medical history and clinical presentation in clinical decision making.IS

Development of a Preoperative Neuroscience Educational Program for Patients with Lumbar Radiculopathy

ABSTRACT Louw A, Butler DS, Diener I, Puentedura EJ: Development of a preoperative neuroscience educational program for patients with lumbar radiculopathy. Am J Phys Med Rehabil 2013;92:00Y00. Postoperative rehabilitation for lumbar radiculopathy has shown little effect on reducing pain and disability. Current preoperative education programs with a focus on a biomedical approach feature procedural and anatomical information, and these too have shown little effect on postoperative outcomes. This report describes the development of an evidence-based educational program and booklet for patients undergoing lumbar surgery for radiculopathy using a recently conducted systematic review of neuroscience education for musculoskeletal pain. The previous systematic review produced evidence for neuroscience education as well as best-evidence synthesis of the content and delivery methods for neuroscience education for musculoskeletal pain. These evidence statements were extracted and developed into patient-centered messages and a booklet, which was then evaluated by peer and patient review. The neuroscience educational booklet and preoperative program convey key messages from the previous systematic review aimed at reducing fear and anxiety before surgery and assist in developing realistic expectations regarding pain after surgery. Key topics include the decision to undergo surgery, pain processing, peripheral nerve sensitization, effect of anxiety and stress on pain, surgery and the nervous system, and decreasing nerve sensitization. Feedback from the evaluations of the booklet and preoperative program was favorable from all review groups, suggesting that this proposed evidence-based neuroscience educational program may be ready for clinical application

The development of a multidimensional instrument to assess the severity, functional limitation and psychosocial restriction in individuals with chronic headache

Philosophiae Doctor - PhDHeadache disorders constitute a public-health problem which impacts on individuals and society. The functional limitation and psychosocial restriction, caused by chronic headache, may be a more reliable indication of the severity of the disorder than the pain intensity and temporal headache pattern itself. Evaluation of all these parameters may improve health care for individuals suffering from chronic headache. The ultimate purpose of this study was to develop and validate a multidimensional questionnaire to assess the severity and impact of headache in individuals suffering from chronic headache. The study was carried out in six phases, each stage building on the previous ones. A quantitative retrospective review of 450 patients' clinical files was executed to identify the elements of complaint of these patients. This was followed by a literature review of existing headache-related health measures and construction of a theoretical framework for the study. A questionnaire was developed based on these findings. This questionnaire was then tested for face and content validity in a chronic headache population sample (n=60) and physiotherapists working with these patients (n=18). The questionnaire was further refined by a small qualitative study, making use of small group discussions (n=10). After the suggested modifications were made, the Multidimensional Chronic Headache Questionnaire (MCHQ) was tested for stability in a group of chronic headache patients (n=21), who completed the questionnaire twice with a one-week intervening period with no intervention. It was then tested for responsiveness, where patients completed the questionnaire prior to, and after, an episode of treatment. The Wilcoxon Signed Rank Sum Test was used to detect significant differences (and hence responsiveness). Lastly, all the MCHQ's (n=148) that were completed during the course of the study were analised to establish the homogeneity of item content (Chronbach alpha values), and the construct validity of the instrument in terms of item structure (exploratory factor analysis). The retrospective review of patients' perceptions of the severity and impact of their chronic headache indicated that many of the patients experienced moderate to severe limitation of function and psychosocial restriction. Although many domains of headache-related health were represented in published questionnaires reviewed for this study, no instrument that assesses both the perceived severity and a wide range of impact was found. The MCHQ was developed from this study to measure these parameters. The items in the questionnaire were based on the retrospective study and existing questionnaires utilised in the chronic headache population. The face and content validity of the first draft of the instrument was found to be good. The stability of the questionnaire was very good, with Pearson's correlation coefficients of greater than 0.9334 for all repeated items. Responsiveness was very good, with all items found to be responsive to change (with probability values of p0.6647), and preliminary construct validity was suggested by demonstration of eight distinct factors that were clearly interpretable (one in the severity and seven in the impact domain). These suggested that severity is unidimensional, and that seven dimensions of impact are assessed in the MCHQ (functional limitations, two emotional dimensions, relationship restrictions, and three headache trigger dimensions). Positive linear correlations between severity and impact suggested that the higher the severity, the more severe the impact on the individual's quality of life (r=0.5183; p<.OOOI). These tests suggested preliminary construct validity for the questionnaire. The researcher concluded that severe and frequent headache has a considerable impact on the individual and that the multiple facets of headache-related health can be measured appropriately using this instrument. The Multidimensional Chronic Headache Questionnaire is a new instrument to assess headache-related health in terms of both severity and multidimensional impact on individuals, which can be utilised in a once-off health assessment as well as an outcome measure for therapy
