Clinical and economic burden of low back pain in low- and middle-income countries: a systematic review.

OBJECTIVES: Low back pain (LBP) is the leading cause of disability and work absenteeism globally, and it poses significant clinical and economic burden to individuals, health systems and the society. This study aimed to synthesise the clinical and economic burden of LBP in low-income and middle-income countries (LMICs). METHODS: A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed. PubMed, Medline, CINAHL, PsycINFO, AMED, Embase and Scopus databases were systematically searched for studies that examined the clinical and economic burden of LBP in LMICs, published from inception to 10 December 2021. Only studies with clearly stated methodologies and published in English were eligible for review. RESULTS: Nine studies met the inclusion criteria and were reviewed. Of these, three of them were clinical burden studies. The mean Newcastle-Ottawa Quality Assessment Scale (NOS) score of the included studies was 4, with an average from 3 to 6. The included studies were conducted in Argentina, Brazil, China, Ethiopia, Nigeria and Republic of Serbia. The rates of hospitalisation due to LBP ranged between 13.4% and 18.7%. Due to variation of methodological approaches, the reported cost estimates were inconsistent across the studies. A total cost of US$2.2 billion per population and US$1226.25 per patient were reported annually due to LBP. CONCLUSION: This systematic literature review suggests that LBP is associated with significantly high rates of hospitalisation and costs. As LBP is an important threat to the population, health professionals and policymakers are to put in place appropriate programmes to reduce the clinical and economic burden associated with LBP and improve the health outcomes of individuals with this condition in LMICs.

Patterns, facilitators and barriers to physical activity among Nigerian pregnant women.

Introduction: pregnancy is associated with sedentary behaviors and/or low levels of physical activity (PA). This study aimed to assess patterns, barriers, and facilitators of PA among pregnant women. Methods: a convergent parallel mixed method design study involving a concurrent collection of quantitative (n=198) and qualitative (n=36) data was carried out. Respondents were drawn from five selected health care facilities in Ile-Ife, Osun state, South-West, Nigeria. Physical activity was assessed using the pregnancy physical activity questionnaire. Focus group discussions were used to qualitatively explore barriers and facilitators of PA. Quantitative data were analyzed using descriptive and inferential statistics, while qualitative data were analyzed using thematic content analysis. Results: the mean total PA score for the population was 118.663±81.522 mets-min/wk. While it was 118.743±92.062 mets-min/wk, 113.861±72.854 mets-min/wk, and 25.429±87.766 mets-min/wk for the first, second, and third trimester respectively. The respondents engaged more in moderate (44.27±37.07) than vigorous (13.89±18.87) intensity PA. Respondents in the third trimester had the highest and the least scores for household-related PA (45.7±33.0) and vigorous-intensity PA (10.0±14.0) respectively. Major themes that emerged on enablers and barriers of PA engagement during pregnancy were related to intrapersonal, interpersonal, availability of specialized health personnel and policy for PA, good built environment/neighborhood factors, and pervading cultural beliefs and myths about pregnancy. Conclusion: moderate intensity and household-related PA were most common among Nigerian pregnant women. Contextual facilitators and barriers to PA during pregnancy were largely related to intrapersonal, interpersonal, environmental or organizational, policy, and cultural factors.

Cost effectiveness of virtual reality game compared to clinic based McKenzie extension therapy for chronic non-specific low back pain.

Background: Low-back pain (LBP) is a major public health problem globally and its direct and indirect healthcare costs are growing rapidly. Virtual reality involving the use of video games or non-game applications are alternatives to conventional face-to-face physical therapy for LBP. The purpose of this study was to assess the cost-effectiveness of Back Extension-Virtual Reality Game (BE-VRG) compared to Clinic-based McKenzie therapy (CBMT) for chronic non-specific LBP in Nigeria. Methods: Patients with chronic non-specific LBP were randomised into either BE-VRG or CBMT group. Patients' level of disability was assessed using Oswestry Disability Index (ODI) at week 4 and week 8. ODI was mapped to SF-6D to generate quality adjusted life years (QALYs) used for cost-effectiveness analysis. Resource use and costs were assessed based on rehabilitation services from a healthcare perspective. Cost-effectiveness analysis which included direct healthcare costs was conducted. Incremental cost per QALY was also calculated. Results: Forty-six patients (BE-VRG, n = 22; CBMT, n = 24) with the mean (±SD) age of 32.6 ± (11.5) years for BE-VRG and 48.8 ± (10.2) years for CBMT intervention completed in this study. The mean direct health costs per patient were USD100.67 and USD106.3 for BE-VRG and CBMT, respectively. The mean quality adjusted life years at week 4 and week 8 were (BE-VRG, 0.0574 ± (0.002); CBMT, 0.0548 ± (0.002)); and (BE-VRG; 0.116 ± (0.002); CBMT; 0.114 ± (0.004)), respectively. Incremental cost-effectiveness ratio showed that BE-VRG arm was less costly and more effective than CBMT. Conclusion: The findings of this study suggest that BE-VRG was cost saving for chronic non-specific LBP compared to CBMT. This evidence could guide policy makers, payers and clinicians in evaluating BE-VRG as a treatment option for people with chronic non-specific LBP.

Prevalence, pattern and risk factors for work-related musculoskeletal disorders among Nigerian plumbers.

Plumbing work is more manually driven in low-and-middle income countries (LMICs), and the prevalence of work-related musculoskeletal disorders (WMSDs) among workers who engage in plumbing in LMICs may be worse than earlier reports from developed countries. This study aimed to assess the prevalence, pattern and risk factors for work-related musculoskeletal disorders (WMSDs) among Nigerian plumbers. A total of 130 consenting plumber participated in this cross-sectional study. The Nordic Musculoskeletal questionnaire and the Job Factor Questionnaire were used to assess information on prevalence and pattern of WMSDs; and perceptions regarding work-related risks factors for WMSDs. Descriptive (mean, frequency, range, percentage and standard deviation) and inferential (Chi-square) statistics were used to analyze data. Alpha level was set at p<0.05. The mean age of the respondents is 36.56 ± 10.418 years. The mean years of experience and working hours per day are 14.15 ± 9.161 years and 8.28 ± 2.512 hours. Job characteristics were mostly installation of pipes and fixtures (99.2%), equipment and fixtures prior to installation (96.9%), and testing of plumbing system for leaks (88.5%). 12-month and 7-day prevalence of WMSDS were 84.6% and 50.8%. Low-back (63.8%), neck (55.4%) and knee (50%) were the most affected body sites. Having WMSDs limits normal activities involving the low-back (32.3%), knee (25.4%) and neck (23.8%). There was significant association between 12-month prevalence of WMSDs and use of saws and pipe cutters (χ2 = 4.483; p = 0.034), while sites of affectation had significant association with 12-month and 7-day prevalence of WMSDs (p<0.05) respectively. Nigerian plumbers have a high prevalence of WMSDs affecting most commonly the low back, neck and knee. Plumbing job factors pose mild to moderate risk to developing WMSDs, and use of saws and pipe cutters significantly influence WMSDs.

Translation, Cross-Cultural Adaptation, and Psychometric Testing of Yoruba Version of the EQ-5D Questionnaire in Patients With Musculoskeletal Disorders.

Background: The EuroQol-5 Dimension (EQ-5D) is a generic self-administered questionnaire used for the measurement and economic valuation of a wide range of health conditions, which necessitates its existence and adaptation in different languages. Currently, the tool does not exist in any Nigerian language. This study aimed to translate, cross-culturally adapt, and determine the reliability and validity of the Yoruba version of the EQ-5D-5L questionnaire. Methods: The International Quality of Life Assessment (IQOLA) project guidelines, involving forward translation, reconciliation and harmonization, backward translation, and reconciliation of problematic items were used in the Yoruba translated version of the EQ-5D-5L (EQ-5D-Yor). A total of 113 and 109 persons with musculoskeletal disorders participated in the validity and 7-day test-retest reliability testing of the EQ-5D-Yor. Convergent and discriminant validity of the EQ-5D-Yor were determined using the Yoruba version of the 12-Item Short-Form Health Survey (SF-12) (SF-12-Y) and Visual Analog Scale (VAS). Data were analyzed using descriptive and inferential statistics of Spearman correlation, Intra-Class Correlation, Cronbach alpha, and multi-trait scaling analysis. Alpha level was set as p < 0.05. Results: The construct validity of the EQ-5D-Yor yielded Spearman rho ranging from 0.438 to 1.000, with the EQ-VAS having the highest co-efficient (r = 1.000; p = 0.001). The convergent validity of the EQ-5D-Yor index with scales and domains of the SF-12-Y yielded no significant correlations (p < 0.05), except for the physical functioning scale (r = -0.709, p = 0.001). On the other hand, the divergent validity of the EQ-5D-Yor index with VAS yielded a moderate negative correlation (r = -0.482; p = 0.001). The Intra-class Correlation Coefficient (ICC) and Cronbach's alpha for the test-retest reliability of the EQ-5D-Yor were 1.000 and 0.968. The confirmatory factor analysis showed the factor loadings were poor when including VAS in the model. Conclusion: The EQ-5D-Yor has acceptable validity and reliability and can be used as a valid tool among Yoruba speaking population with musculoskeletal disorders.

Patients' and physiotherapists' perspectives on implementing a tailored stratified treatment approach for low back pain in Nigeria: a qualitative study.

BACKGROUND: Stratified care has the potential to be efficient in addressing the physical and psychosocial components of low back pain (LBP) and optimise treatment outcomes essential in low-income countries. This study aimed to investigate the perceptions of physiotherapists and patients in Nigeria towards stratified care for the treatment of LBP, exploring barriers and enablers to implementation. METHODS: A qualitative design with semistructured individual telephone interviews for physiotherapists and patients with LBP comprising research evidence and information on stratified care was adopted. Preceding the interviews, patients completed the Subgroups for Targeted Treatment tool. The interviews were recorded, transcribed and analysed following grounded theory methodology. RESULTS: Twelve physiotherapists and 13 patients with LBP participated in the study (11 female, mean age 42.8 (SD 11.47) years). Seven key categories emerged: recognising the need for change, acceptance of innovation, resistance to change, adapting practice, patient's learning journey, trusting the therapist and needing conviction. Physiotherapists perceived stratified care to be a familiar approach based on their background training. The prevalent treatment tradition and the patient expectations were seen as major barriers to implementation of stratified care by the physiotherapists. Patients see themselves as more informed than therapists realise, yet they need conviction through communication and education to cooperate with their therapist using this approach. Viable facilitators were also identified as patients' trust in the physiotherapist and adaptations in terms of training and modification of the approach to enhance its use. CONCLUSION: Key barriers identified are the patients' treatment expectations and physiotherapists' adherence to the tradition of practice. Physiotherapists might facilitate implementation of the stratified care by communication, hierarchical implementation and utilisation of patients' trust. Possibilities to develop a consensus on key strategies to overcome barriers and on utilisation of facilitators should be tested in future research.

Infant-carrying techniques: Which is a preferred mother-friendly method?

Infant carrying is still trendy among African mothers than in other climes, however, carrying techniques vary mostly along cultural divides. Using a pretest-posttest quasi-experimental design, the authors evaluated the effect of three types of infant-carrying techniques on cardiopulmonary function, metabolic expenditure, fatigue demand, and locomotion. Front wrap infant-carrying technique led to a marginally higher cardiopulmonary demand. Hip sling technique resulted in greater metabolic expenditure and oxygen consumption with high rate of perceived exertion, while back wrap technique did not significantly decrease locomotion parameters. The authors recommend back wrap infant carrying technique based on its slightly lower effects on cardiopulmonary function, metabolic expenditure, fatigue demand, and locomotion.

Economic Impact of COVID-19 lockdown on households.

INTRODUCTION: this study evaluated the economic impact of the COVID-19 lockdown on individuals and households. METHODS: a cross-sectional online survey was used to collect data. Nigerian citizens who were domiciled or restricted from travelling abroad for no less than one month since the COVID-19 restrictions and lockdown were recruited into the study through focal persons purposively selected across the different states in Nigeria. Using WhatsApp® platform, the respondents completed the survey on household income and expenditure before and during the lockdown. Economic burden of COVID-19 lockdown on individuals and families was estimated using a prevalence-based cost of illness approach. RESULTS: four hundred and four (male = 242; female = 162) individuals have participated in the study. The mean (SD) age of the respondents was 30.98 (10.92) years. Monthly income showed no statistically significant difference (p = 0.73) before and during lockdown. The overall household expenditure before and during the lockdown periods were USD 320 and USD 290. The total mean monthly costs for COVID-19 and non-COVID-19 health related problems were ₦11746.25 (USD30.79) and ₦11784.9 (USD 30.89), respectively. Household expenditure for hand sanitizers, facemasks, hand gloves, and disinfectants increased significantly during the COVID-19 restriction lockdown (p < 0.05). However, expenditure on education, water, electricity, fuel, internet data, clothing and wears, toiletries decreased significantly during the lockdown period (p < 0.05). CONCLUSION: this study suggests that the costs of continuing COVID-19 restrictions could have huge economic consequences on households and health system.

Validation of the Yoruba Version of the Pain Self-Efficacy Questionnaire in Patients with Chronic Low Back Pain.

STUDY DESIGN: Cultural adaptation and psychometric analysis. OBJECTIVE: This study determined the test-retest reliability, acceptability, internal consistency, divergent validity of the Yoruba pain self-efficacy questionnaire (PSEQ-Y). It also examined the ceiling and floor effects and the small detectable change (SDC) of the PSEQ-Y among patients with chronic low back pain (LBP). SUMMARY OF BACKGROUND DATA: There are various indigenous language translations of the PSEQ and none adapted to African language. However, translations of the PSEQ into Nigerian languages are not readily available. METHODS: The validity testing phase of the study involved 131 patients with LBP, while 83 patients with LBP took part in the reliability phase. Following the Beaton recommendation for cultural adaptation of instruments, the PSEQ was adapted into the Yoruba language. The psychometric properties of the PSEQ-Y determined comprised: internal consistency, divergent validity, test-retest reliability, and SDC. RESULTS: The mean age of the participants was 52.96 ±â€Š17.3 years. The PSEQ-Y did not correlate with the Yoruba version of Visual Analogue Scale (VAS-Y) scores (r = -0.05; P = 0.59). The values for the internal consistency and the test-retest reliability of the PSEQ-Y were 0.79 and 0.86, with the 95% confidence interval of the test-retest reliability ranging between 0.82 and 0.90. The standard error of measurement (SEM) and the SDC of the PSEQ-Y were 1.2 and 3.3, respectively. The PSEQ-Y had no floor or ceiling effect, as none of the respondents scored either the minimal or maximal scores. CONCLUSION: This is the first study in Nigeria to culturally adapt PSEQ. The PSEQ-Y showed adequate psychometric properties similar to existing versions. Therefore, the tool can be used to assess pain self-efficacy in clinical and research settings and help to improve the health outcomes of patients chronic LBP.Level of Evidence: 3.

Exploração qualitativa do itinerário terapêutico de crianças com deficiência física na Nigéria usando análise de conteúdo temática / Exploración cualitativa del itinerario terapéutico de niños con discapacidades físicas en Nigeria utilizando análisis de contenido temático / Qualitative exploration into therapeutic itinerary of children with physical disabilities in Nigeria using thematic content analysis

Resumo Objetivo Explorar o itinerário terapêutico na busca de cuidados para crianças com deficiências físicas pelos cuidadores. Métodos Um plano qualitativo descritivo que recrutou nove cuidadores de crianças com deficiência física, com consentimento, que frequentavam um Hospital Universitário Nigeriano. Foi utilizado um guia de entrevista semi-estruturado para coletar dados sobre o itinerário terapêutico, que foi definido como os caminhos percorridos pelos indivíduos para resolver o seu problema de saúde. As entrevistas foram gravadas em áudio e transcritas literalmente. Os dados foram analisados utilizando a análise do conteúdo temático. Resultados os temas emergentes revelaram que os cuidadores iniciaram o itinerário terapêutico para os respetivos filhos após a observação de quaisquer deficiências que vão para além de doenças casuais. A falta de capacidade dos hospitais privados, que servem como ponto inicial de entrada na busca de cuidados, encorajou a procura por cuidados nos hospitais públicos, lares espirituais, e clínicas tradicionais. A entrada na fisioterapia dependia de auto-referências, referências por parentes e médicos. Cuidar de crianças com deficiência física prejudicou de modo significativo a vida social, as finanças, o trabalho do cuidador; e expectativas não alcançadas de que a criança melhorasse o mais cedo possível encorajaram um pluralismo contínuo. Conclusão e implicações para a prática O fato de ter crianças com deficiências e de ter havido atraso nos progressos levou os cuidadores a práticas múltiplas e complexas na busca de cuidados de saúde.

Resumen Objetivo Explorar el itinerario terapéutico para la búsqueda de cuidado de niños con discapacidad física por parte de los cuidadores. Métodos Un diseño cualitativo descriptivo que recluta a nueve cuidadores de niños con discapacidades físicas que asisten a un hospital universitario de Nigeria. Se utilizó una guía de entrevista semiestructurada para recopilar datos sobre el itinerario terapéutico que se definió como los caminos que recorren los individuos para abordar su problema de salud. Las entrevistas fueron grabadas en audio y transcritas textualmente. Los datos se analizaron mediante análisis de contenido temático. Resultados Los temas emergentes revelaron que los cuidadores iniciaron un itinerario terapéutico para sus hijos al observar cualquier impedimento que vaya más allá de las enfermedades casuales. La falta de capacidad en los hospitales privados, que sirve como punto inicial de entrada en la búsqueda de atención, fomenta la vacilación en los hospitales públicos, hogares espirituales y clínicas tradicionales. La entrada en fisioterapia dependía de las autorremisiones, las derivaciones de familiares y médicos. El cuidado de niños con discapacidad física afectó significativamente la vida social, las finanzas y el trabajo del cuidador; y las expectativas no satisfechas de que un niño se recupere lo antes posible fomentaron el pluralismo continuo. Conclusión e implicaciones para la práctica El hecho de que los niños presentaran discapacidades e hitos retrasados condujo a múltiples prácticas complejas de búsqueda de atención médica entre los cuidadores. Por lo tanto, estos cuidadores se vuelven médicos pluralistas y encubiertamente no se adhieren a las prescripciones de tratamiento hospitalario.

Abstract Objective To explore the therapeutic itinerary for seeking care for children with physical disabilities by caregivers. Methods A descriptive qualitative design recruiting nine consenting caregivers of children with physical disabilities attending a Nigerian Teaching Hospital. A semi-structured interview guide was used to collect data on therapeutic itinerary which was defined as the paths taken by individuals to address their health problem. Interviews were audio-recorded and transcribed verbatim. Data was analyzed using thematic content analysis. Results Emerging themes revealed that caregivers commenced therapeutic itinerary for their children upon observation of any impairments that go beyond casual illnesses. Lack of capacity in private hospitals, which serves as initial point of entry into care seeking, encourage vacillation into public hospitals, spiritual homes, and traditional clinics. Entry into physiotherapy was dependent on self-referrals, referrals by relatives, and physicians. Caring for children with physical disability significantly affected caregiver's social life, finances, work; and unmet expectations for a child to get well as soon as possible encouraged continuous pluralism. Conclusion and implications for the practice Having children presenting with impairments and delayed milestones led to complex multiple health care seeking practices among caregivers. Thus, these caregivers become medical pluralists and covertly non-adherent to hospital treatment prescriptions.

Itinerário terapêutico de sobreviventes de acidente vascular cerebral em um hospital terciário nigeriano / Therapeutic itinerary of stroke survivors in a Nigerian tertiary hospital

RESUMO Objetivo analisar o itinerário terapêutico de sobreviventes de acidente vascular cerebral, desde sua ocorrência até a reabilitação. Métodos itinerário terapêutico percorrido por 12 sobreviventes de acidente vascular cerebral para resolver seus problemas de saúde foi explorado usando entrevistas em profundidade e análise temática. Resultados as rotas dos sobreviventes foram influenciadas pelo tipo e estado do paciente no início do acidente vascular cerebral. A falta de capacidade contribuiu para indecisão entre buscar atendimento em hospitais privados ou públicos. A entrada na fisioterapia dependeu da demanda espontânea e de encaminhamentos realizados por médicos que atuam como sentinelas dos pacientes. O acidente vascular cerebral afetou significativamente a vida social dos sobreviventes. A extensão do comprometimento do acidente vascular cerebral e expectativas não atendidas promovem o pluralismo médico entre os sobreviventes. Conclusão sobreviventes de acidente vascular cerebral estão envolvidos em itinerários terapêuticos complexos e extensos, caracterizados pela prática de busca de múltiplos cuidados.

ABSTRACT Objective to analyze the therapeutic itinerary of stroke survivors from stroke occurrence to rehabilitation. Methods therapeutic itinerary - route taken by individuals to solve their health problems, of 12 stroke survivors was explored using in-depth interviews and was thematically analyzed. Results stroke survivors' routes were influenced by type of stroke and the state of the patient at onset of stroke. Lack of capacity facilitates vacillation from private to the public hospital settings. Entry into physiotherapy was dependent on self-referrals and referrals from physicians who often serve as gatekeeper of patients. Stroke significantly affected social life of stroke survivors, and the extent of stroke impairment and unmet expectations promotes medical pluralism among the survivors. Conclusion stroke survivors are involved in intricate and lengthy therapeutic itineraries that are characterized by multiple care seeking practice.

Prevalence and correlates of bullying in physiotherapy education in Nigeria.

BACKGROUND: Bullying is an unexpressed part and parcel of medical education but it is largely unexplored in physiotherapy. This study assessed the prevalence and socio-demographic correlates of bullying in physiotherapy education in Nigeria. METHODS: Two hundred and nineteen clinical physiotherapy students from three purposively selected Federal Universities in Nigeria participated in this study. Following a cross-sectional design, the Students Perception of Professor Bullying Questionnaire (SPPBQ) was used to obtain information on bullying. The SPPBQ includes a working definition of lecturer bullying followed by other sections inquiring about lecturers bullying experiences. Data was collected on socio-demographic characteristics, bullying experiences and availability of adequate policy and support on bullying. Descriptive and inferential statistics were used analyze data. Alpha level was set at p < 0.05. RESULTS: Lifetime and point prevalence of bullying in physiotherapy education were 98.6 and 99.1%. 94.5% of the respondents had witnessed physiotherapy students bullying and there was a 100% rate of 'no attempt' to stop a physiotherapy lecturer from bullying. 38.4 and 44.7% of the respondents believed there was adequate school policy and support available on bullying. There was no significant association between bullying and each of age (휒2 = 0.117, p = 0.943), gender (휒2 = 0.001, p = 0.974), level of study (휒2 = 0.000, p = 0.995) and any specific university (휒2 = 1.343, p = 0.511). CONCLUSION: There is high lifetime and point prevalence of bullying in physiotherapy education in Nigeria, which are largely unchallenged or redressed. Being a clinical physiotherapy student ordinarily predisposes to bullying without necessary contributions of intrinsic and extrinsic factors.

Cross-cultural adaptation and psychometric evaluation of the Yoruba version of Oswestry disability index.

INTRODUCTION: Low-Back Pain (LBP) is a common public health problem that is often worsened by maladaptive beliefs and disability. Thus, necessitating the need for availability of outcome measures to assess these sequelae among patients with chronic LBP. This study aimed to cross-culturally adapt and determine the psychometric properties of the Yoruba version of the ODI (ODI-Y). METHODS: The ODI-Y was cross-culturally adapted following the process involving forward translation, synthesis, backward translation, expert review, and pilot testing. Internal consistency and test-retest reliability of the ODI-Y were determined using the Cronbach's alpha and intra-class correlation. Other psychometric properties explored included the factor structure, convergent validity, standard error of measurement and the minimal detectable change. RESULTS: One hundred and thirty-six patients with chronic LBP took part in the validation of the ODI-Y; 86 of these individuals took part in the test-retest reliability (within 1-week interval) of the translated instrument. The mean age of the respondents was 50.5±10.6years. The ODI-Y showed a high internal consistency, with a Cronbach's alpha (α) of 0.81. Test-retest of the Yoruba version of the ODI within 1-week interval yielded an Intra-Class Correlation coefficient of 0.89. The ODI-Y yielded a three-factor structure which accounted for 61.56% of the variance. Correlation of ODI-Y with the visual analogue scale was moderate (r = 0.30; p = 0.001). The standard error of measurement and minimal detectable change of the ODI-Y were 2.0 and 5.5. CONCLUSIONS: The ODI was adapted into the Yoruba language and proved to have good psychometric properties that replicated the results of other obtainable versions. We recommend it for use among Yoruba speaking patients with LBP.

Cross-cultural adaptation and validation of the Igbo language version of the stroke-specific quality of life scale 2.0.

INTRODUCTION: availability of the Stroke-Specific Quality of Life scale 2.0 (SS-QoL(E)) in Yoruba and Hausa, two of the three major indigenous languages in Nigeria have the potential to promote its uptake among these population, however, its non-availability in the Igbo languages makes its use restrictive among the south-eastern Nigerians. This study was aimed at cross-culturally adapting and assessing validity and reliability of the Igbo version of the SS-QoL. METHODS: the SS-QoL(E) was cross-culturally adapted to Igbo following the American Association of Orthopaedic Surgeons' guideline. This involved forward and back-translations, expert committee review, pretesting and cognitive debriefing interview to produce the final Igbo version, SS-QoL(I). The validity and reliability test involved 50 consenting Igbo stroke survivors. The construct validity was assessed by administering SS-QoL(E) and SS-QoL(I) on all 50 respondents, while SS-QoL(I) was re-administered at 7-day interval to assess test-retest reliability. Each scale was administered in random order. Data were analysed using Spearman's correlation, Wilcoxon's signed-rank test, Cronbach's alpha, Intra-class Correlation Coefficient (ICC), independent t-test and one-way ANOVA at p<0.05. RESULTS: respondents' domains scores on SS-QoL(E) and SS-QoL(I) did not differ significantly except in mobility and work (r=0.58 to 0.87; p=0.001). Cronbach's alpha was 0.69 to 0.87 for domains scores. The ICC ranged from 0.48 to 0.84, while no significant differences was found across different age groups or gender for the domains or overall scores of SS-QoL(I). CONCLUSION: the Igbo version of the SS-QoL has limited alterations from the original version and has moderate to excellent validity and reliability values.

Comparative effectiveness of two stabilization exercise positions on pain and functional disability of patients with low back pain.

The study investigated the effects of two stabilization exercise positions (prone and supine) on pain intensity (PI) and functional disability (FD) of patients with nonspecific chronic low back pain (NSCLBP). The 56 subjects that completed the study were randomly assigned into stabilization in prone (SIP) (n=19), stabilization in supine (SIS) (n=20), and prone and supine (SIPS) position (n=17) groups. Subjects in all the groups received infrared radiation for 15 min and kneading massage at the low back region. Subjects in SIP, SIS, and SIPS groups received stabilization exercise in prone lying, supine lying and combination of both positions respectively. Treatment was applied twice weekly for eight weeks. PI and FD level of each subject were measured at baseline, 4th and 8th week of the treatment sessions. Data were analyzed using descriptive and inferential statistics. The alpha level was set at P<0.05. Within-group comparison indicated that PI and FD at the 4th and 8th week were significantly reduced (P<0.001) when compared with baseline in all the three groups. However, the result showed that there was no significant difference in the PI and FD at the 8th week (P>0.05) of the treatment sessions across the three groups when compared. It can be concluded that stabilization exercises carried out in prone, supine and combination of the two positions were equally effective in managing pain and disability of patients with NSCLBP. However, no position was superior to the other.

Cross-cultural Adaptation, Reliability, and Validity of the Yoruba Version of the Roland-Morris Disability Questionnaire.

STUDY DESIGN: A translation, cross-cultural adaptation, and psychometric analysis. OBJECTIVE: The aim of this study was to translate, cross-culturally adapt, and validate the Yoruba version of the RMDQ. SUMMARY OF BACKGROUND DATA: The Roland-Morris Disability Questionnaire (RMDQ) is a valid outcome tool for low back pain (LBP) in clinical and research settings. There seems to be no valid and reliable version of the RMDQ in the Nigerian languages. METHODS: Following the Guillemin criteria, the English version of the RMDQ was forward and back translated. Two Yoruba translated versions of the RMDQ were assessed for clarity, common language usage, and conceptual equivalence. Consequently, a harmonized Yoruba version was produced and was pilot-tested among 20 patients with nonspecific long-term LBP (NSLBP) for cognitive debriefing. The final version of the Yoruba RMDQ was tested for its construct validity and re-retest reliability among 120 and 87 patients with NSLBP, respectively. RESULTS: Pearson product moment correlation coefficient (r) of 0.82 was obtained for reliability of the Yoruba version of the RMDQ. The test-retest reliability of the Yoruba RMDQ yielded Cronbach alpha 0.932, while the intraclass correlation (ICC) ranged between 0.896 and 0.956. The analysis of the global scores of both the English and Yoruba versions of the RMDQ yielded ICC value of between 0.995 (95% confidence interval 0.996-0.997), with the item-by-item Kappa agreement ranging between 0.824 and 1.000. The external validity of RMDQ using Quadruple Visual Analogue Scale was r = -0.596 (P = 0.001). The Yoruba version of the RMDQ had no floor/ceiling effects, as no patient achieved either of the maximum or the minimum possible scores. CONCLUSION: The Yoruba version of the RMDQ has excellent reliability and validity and may be an appropriate outcome tool for clinical and research purposes among Yoruba-speaking patients with LBP.

Awareness and Knowledge of Occupational Therapy among Nigerian Medical and Health Sciences Undergraduates.

OBJECTIVE/BACKGROUND: Consequent to the introduction of occupational therapy (OT) training programmes in Nigeria in the past decade, this study sought to assess the awareness and knowledge of Nigerian medical and other health career undergraduates about OT. METHODS: Three hundred and eighty-one undergraduates and students of other health disciplines from the College of Health Sciences, Obafemi Awolowo University (OAU), Ile-Ife, Nigeria responded to a validated three section questionnaire assessing their awareness and knowledge about OT. The collected data were analysed using descriptive statistics of mean and percentages and inferential statistics of chi-square test of association. RESULTS: The mean age of the respondents was 20.96 ±2.88 years. Over 80% of the respondents were aware of the OT profession, with higher rates among male respondents (83.7%), students in the 2nd year of study (94.7%), and those in the medical rehabilitation programme (99.1%). Amongst the respondents, < 40% had good knowledge of OT while a majority had knowledge ranging from poor to moderate (62.7%). Respondents' course of study and level of study were significantly associated with awareness and knowledge about OT. CONCLUSION: Nigerian medical and health sciences undergraduates had high awareness, but poor to moderate knowledge about the OT profession, roles, and work settings. Level of awareness and knowledge about OT were significantly influenced by the rehabilitation-related course of study and lower level of study. Replication of similar studies in countries with different cultural backgrounds is suggested.

Translation, cross-cultural adaptation and psychometric evaluation of yoruba version of the short-form 36 health survey.

BACKGROUND AND OBJECTIVE: The Short-Form Health Survey (SF-36) is a valid quality of life tool often employed to determine the impact of medical intervention and the outcome of health care services. However, the SF-36 is culturally sensitive which necessitates its adaptation and translation into different languages. This study was conducted to cross-culturally adapt the SF-36 into Yoruba language and determine its reliability and validity. METHODS: Based on the International Quality of Life Assessment project guidelines, a sequence of translation, test of item-scale correlation, and validation was implemented for the translation of the Yoruba version of the SF-36. Following pilot testing, the English and the Yoruba versions of the SF-36 were administered to a random sample of 1087 apparently healthy individuals to test validity and 249 respondents completed the Yoruba SF-36 again after two weeks to test reliability. Data was analyzed using Pearson's product moment correlation analysis, independent t-test, one-way analysis of variance, multi trait scaling analysis and Intra-Class Correlation (ICC) at p < 0.05. RESULTS: The concurrent validity scores for scales and domains ranges between 0.749 and 0.902 with the highest and lowest scores in the General Health (0.902) and Bodily Pain (0.749) scale. Scale-level descriptive result showed that all scale and domain scores had negative skewness ranging from -2.08 to -0.98. The mean scores for each scales ranges between 83.2 and 88.8. The domain scores for Physical Health Component and Mental Health Component were 85.6 ± 13.7 and 85.9 ± 15.4 respectively. The convergent validity was satisfactory, ranging from 0.421 to 0.907. Discriminant validity was also satisfactory except for item '1'. The ICC for the test-retest reliability of the Yoruba SF-36 ranges between 0.636 and 0.843 for scales; and 0.783 and 0.851 for domains. CONCLUSION: The data quality, concurrent and discriminant validity, reliability and internal consistency of the Yoruba version of the SF-36 are adequate and it is recommended for measuring health-related quality of life among Yoruba population.

Prevalence and modes of complementary and alternative medicine use among peasant farmers with musculoskeletal pain in a rural community in South-Western Nigeria.

BACKGROUND: Anecdotally, use of Complementary and Alternative Medicine (CAM) for Musculoskeletal Pain (MSP) is common in Nigeria; however, there seems to be a dearth of empirical data on its prevalence and mode of use. This study investigated the prevalence and modes of use of CAM for MSP among farmers in a rural community in South-western Nigeria. METHODS: This cross-sectional survey employed multistage sampling technique guidelines for conducting community survey by the World Health Organization among rural community farmers in Gudugbu village, Oyo State, Nigeria. A questionnaire developed from previous studies and validated by expert reviews was used to assess prevalence and modes of CAM use. Data was analyzed using descriptive and inferential statistics. Alpha level was set at p < 0.05. RESULTS: A total of 230 consenting rural farmers volunteered for this study with a valid response rate of 93.9 % (n = 216). The lifetime, 12-month and point prevalence of CAM for MSP was 96.8 % respectively. Herbal therapy and massage were the predominant types of CAM therapies among previous (83.8 and 80.1 %) and current CAM users (37.5 and 37.5 %). CAM was largely used as sole therapy for MSP (75.5 %) and also in combination with orthodox medicine (23.6 %), and it is consumed on daily basis (21.8 %). CAM was perceived to be very good in maintaining a healthy life (87.1 %) and has less side effects (74 %) and more healthy than taking doctors' prescriptions (63.4 %). CONCLUSION: There is a high prevalence of CAM among Nigerian rural farmers. The most commonly employed CAM for MSP were herbal remedies and massage which are attributable to beliefs on their perceived efficacy.
