Background Telerehabilitation can facilitate multidisciplinary management for people with nonspecific chronic low back pain (NCLBP). It provides health care access to individuals who are physically and economically disadvantaged. Objective This study aimed to evaluate the clinical and cost-effectiveness of telerehabilitation compared with a clinic-based intervention for people with NCLBP in Nigeria. Methods A cost-utility analysis alongside a randomized controlled trial from a health care perspective was conducted. Patients with NCLBP were assigned to either telerehabilitation-based McKenzie therapy (TBMT) or clinic-based McKenzie therapy (CBMT). Interventions were carried out 3 times weekly for a period of 8 weeks. Patients’ level of disability was measured using the Oswestry Disability Index (ODI) at baseline, week 4, and week 8. To estimate the health-related quality of life of the patients, the ODI was mapped to the short-form six dimensions instrument to generate quality-adjusted life years (QALYs). Health care resource use and costs were assessed based on the McKenzie extension protocol in Nigeria in 2019. Descriptive and inferential data analyses were also performed to assess the clinical effectiveness of the interventions. Bootstrapping was conducted to generate the point estimate of the incremental cost-effectiveness ratio (ICER). Results A total of 47 patients (TBMT, n=21 and CBMT, n=26), with a mean age of 47 (SD 11.6) years for telerehabilitation and 50 (SD 10.7) years for the clinic-based intervention, participated in this study. The mean cost estimates of TBMT and CBMT interventions per person were 22,200 naira (US $61.7) and 38,200 naira (US $106), respectively. QALY gained was 0.085 for TBMT and 0.084 for CBMT. The TBMT arm was associated with an additional 0.001 QALY (95% CI 0.001 to 0.002) per participant compared with the CBMT arm. Thus, the ICER showed that the TBMT arm was less costly and more effective than the CBMT arm. Conclusions The findings of the study suggested that telerehabilitation for people with NCLBP was cost saving. Given the small number of participants in this study, further examination of effects and costs of the interventions is needed within a larger sample size. In addition, future studies are required to assess the cost-effectiveness of this intervention in the long term from the patient and societal perspective.

Purpose: To translate, culturally adapt and conduct a psychometric evaluation of the Yoruba version of the Back Beliefs Questionnaire (BBQ) among patients with chronic low-back pain. Methods: The English version of the BBQ was translated into the Yoruba language through a process of forwardbackward translation, reconciliation and harmonization of the reconciled items sequentially. Thereafter, Cronbach's Alpha, Intra-Class Correlation (ICC), Bland-Altman's analysis were used to determine the internal consistency, testretest reliability and limits of agreement of the Yoruba version of the BBQ (BBQ-Y). Other psychometric properties of the BBQ-Y explored comprised acceptability, standard error of measurement (SEM), minimal detectable change (MDC), convergent validity and floor and ceiling effects. While 119 respondents participated in the validity testing, only 51 of them were involved in the reliability testing of the BBQ-Y. Data were analysed using descriptive and inferential statistics. Alpha level was set at p < 0.05. Results: The mean age of the respondents all the respondents was 56.8 ± 8.5 years. The BBQ-Y had excellent acceptability with a global Cronbach Alpha score of 0.71. The SEM and MDC of the BBQ-Y were 2.3 and 6.4. The BBQ-Y ICC score for testretest was 0.89, while the Bland-Altman analysis showing limits of agreements for the test-retest reliability were − 6.84 and 5.70. The convergent validity of the BBQ-Y showed a weak correlation (r = 0.273, p = 0.001) with pain intensity using the visual analogue scale. Conclusion: This is the first study to culturally adapt the BBY-Y and determined its psychometric properties. The BBQ-Y has adequate psychometric properties and it is an appropriate outcome measure for use among Yoruba speaking 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 AE 17.3 years. The PSEQ-Y did not correlate with the Yoruba version of Visual Analogue Scale (VAS-Y) scores (r ¼ -0.05; P ¼ 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.

The younger generations are labeled "digital native" among whom smartphone penetration and adoption is high. However, the health consequences of intense utilization of smartphones as a contributor to the increasing prevalence of musculoskeletal disorders in young adults are less explored. This study investigated patterns of musculoskeletal pain, postural abnormalities, and smartphone usage among undergraduate university students.

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.
