Hearing loss, gait and balance impairments and falls among individuals with sub-acute stroke: A comparative cross-sectional study

Background

The impact of hearing loss in stroke is less explored. This study aimed to compare hearing loss in patients with sub-acute stroke with healthy controls and evaluate its association with gait and balance impairments and falls.

Methods

This study involved 78 ambulant sub-acute stroke patients and 78 age-sex-matched controls. Hearing loss was assessed with pure tone average, while gait and balance impairments were assessed with the Timed Up and Go test, Berg Balance Scale, Functional Gait Assessment and 10-m walk test (gait speed). Fall occurrence was evaluated by a self-report questionnaire.

Results

The prevalence of hearing loss (pure tone average of >25 dB) was higher in stroke patients than in controls (64.1% vs. 35.9%; p < 0.001). The mean pure tone average of stroke patients showed a significant positive correlation with Timed Up and Go test (r = 0.357; p = 0.001) and fall occurrence (r = 0.253; p = 0.025), and a significant negative correlation with Berg Balance Scale (r = -0.299; p = 0.008) and Functional Gait Assessment (r = -0.452; p < 0.001). There was a non-significant negative correlation with gait speed (r = -0.166; p = 0.147). Multiple regression showed that mean pure tone average was associated with Timed Up and Go test (B = 0.096; 95%CI: 0.010, 0.183) and Functional Gait Assessment (B = -0.087; 95%CI: -0.157, -0.017), but not with gait speed (B = -0.003; 95%CI: -0.007, 0.001) and Berg Balance Scale (B = -0.058; 95%CI: -0.165, 0.049).

Conclusion

Hearing loss is more prevalent among patients with sub-acute stroke compared with age-sex-matched controls. Hearing loss is also associated with gait and balance impairments and falls among sub-acute stroke patients. We recommend that hearing screening and rehabilitation be incorporated into post-stroke rehabilitation programmes as part of strategies to improve balance and gait and reduce or prevent falls.

Missed Physiotherapy Appointment and Its Influence on Cost, Efficiency and Patients' Outcomes

Background

Missed appointments is a significant challenge to efficient running of physiotherapy departments and it has cost implications. In this study, wait time, and pattern, predictors and impact of Missed appointments (MAs) on cost, efficiency and recovery time was assessed among Nigerian patients receiving physiotherapy.

Method

In this retrospective study a total of 3,243 physiotherapy appointments were booked between 2009 and 2019 at an Outpatient Physiotherapy Clinic in Nigeria. Data were collected on Missed appointments, on costs of of treatment and on socio-demographic characteristics. The total revenue loss due to missed appointments was calculated as a product of the total of Missed appointments and cost per treatment; recovery time was also estimated.

Results

Missed appointments were 1,701 out of 3,243 booked (52.5%) and the average wait time for the first appointment was 9.6 ± 23.2 days. The proportion of Missed appointments was higher among females (50.2%), patients who were not resident of the same location as the clinic (45.3%), patients with orthopaedic conditions (56.2%) and patients referred from an orthopaedic surgeon (32.8%). Females, those who live within the city, and those with neurological/medical conditions were 1.68, 1.24, and 1.52 times more likely to have Missed appointments compared to males (OR = 1.68, Confidence intervals = 1.44 - 1.96, p = < 0.001), those who live outside the city (OR = 1.24, CI = 1.05 - 1.46, p = 0.01), and to those who have orthopaedic conditions (OR = 1.52, CI = 1.20 - 1.93, p = < 0.001), respectively. Using per treatment schedule cost of N1000 (an equivalent of $ 2.31), a 52.5% Missed appointments rate resulted in lower efficiency of 76.6% with an efficiency ratio of 0.23. Further, a 52.5% Missed appointments rate could potentially impact patient recovery time by 3402 days if Missed appointments slow a patient recovery process by 2 days.

Conclusions

Missed appointments for physiotherapy treatment pose a significant challenge in terms of costs, efficiency, and patient recovery time. Thus, an innovative reminder system may help reduce patients' non-attendance to physiotherapy and its consequences.

Development and Feasibility Testing of a Remote Support Application for Adherence to Home Exercise Programs: A Randomized Pilot Study

Objectives

Poor adherence to home exercise programs (HEPs) is a significant barrier to continuity of care and eventual outcomes, thus requiring innovative mitigating approaches. This study aimed to develop and test the feasibility of a remote support application (RSA) designed to encourage adherence to HEPs.

Methods

Using standard computer programing, an RSA with administrator and user interfaces was developed for mobile phone or tablet. Consenting patients receiving physiotherapy for musculoskeletal conditions (n=19) were randomly assigned into the experimental group (n=10) or the control group (n=9). The experimental group received their customized HEP reminders via the RSA, whereas the control group used conventional paper handouts for HEPs. Adherence to HEPs was assessed over 4 weeks. The feasibility of the RSA was assessed using the Mobile Application Rating Scale and System Usability Scale (SUS) questionnaires. Data were summarized using descriptive and inferential statistics.

Results

The adherence rate of patients in experimental group was significantly higher than that of patients in the control group after 2 weeks [median diff.=-6.0, 95% confidence interval (CI): -8.0 to -5.0; U=5.00; Z=-3.304; P=0.001; r=0.75] and 4 weeks (median diff.=-7.0, 95% CI: -8.0 to -5.0; U=0; Z=-3.695; P<0.001; r=0.84) of intervention. The RSA had a mean SUS score of 82.53±9.04 (out of 100) and a mean app quality rating score of 75.95±4.98 (out of 95).

Conclusions

The use of an RSA to improve adherence to HEPs is feasible for patients with musculoskeletal conditions.

Reference Values for 3-Meter Backward Walk Test among Apparently Healthy Adults

OBJECTIVE

The 3-meter backward walk (3MBW) test is an outcome performance measure to assess backward walking mobility, balance, and risk of fall. However, the lack of baseline values is a potential limitation for its use as a rehabilitation target value or predictor of outcomes. This study aimed at ascertaining a gender- and age-reference value of 3MBW and determining its correlation with sociodemographic and anthropometric variables.

METHODS

A total of 1,601 Nigerian healthy adults participated in this cross-sectional study. 3MBW was measured following standardized procedure on a marked 3-m floor. Anthropometric and sociodemographic parameters were taken. Data were summarized using the descriptive statistics of mean, standard deviation, and percentile (less than the 25th, between the 25th and 75th, and above the 75th percentiles were regarded as low, average, and high 3MBW, respectively).

RESULTS

From this study, less than 2.23 s and 2.60 s were regarded as low risk of fall for males and females, respectively; 2.23-3.00 s and 2.60-3.50 s were regarded as average risk of fall for males and females, respectively, while greater than 3.00-3.9 s and 3.50-3.90 s were regarded as high risk of fall for males and females, respectively. 3MBWT was significantly associated with age (r = 0.51, p = 0.001), sex (r = 0.315, p = 0.001), weight (r = 0.14, p = 0.001), BMI (r = 0.28, p = 0.001), but not height (r = -0.03; p = 0.250).

CONCLUSION

This study provided a reference set of values according to age and gender for 3MBW in healthy individuals. Males have shorter 3MBW than females, and the time taken to accomplish 3MBW increases with age.

Social presence and dynamics of group communication: An analysis of a health professionals WhatsApp group chats

WhatsApp has become a medium of communication with the potential of promoting collaborative environment with peers, patients and general population. Till date, no analysis of professional WhatsApp groups' activities exists in physiotherapy. The official WhatsApp group chats of the Association of Clinical and Academic Physiotherapists of Nigeria (ACAPN) was analyzed. A total of 20760 chats were gleaned from July 2020 to June 2021. Videos, audios and emoticons were excluded in the analysis. Administrative permission to conduct was obtained from ACAPN leadership. Two consenting physiotherapists who had never deleted their ACAPN group chats shared and exported all chats to a Gmail. The social presence theory for group communication was used as the framework of analysis. Thematic content analysis was used to analyze qualitative data. Descriptive statistics of frequency and percentages were used to summarize data. Based on social presence theory classifications, interactive messages (64.5%) followed by cohesive messages (30%) were predominant. Members used the platform more for expression of emotions affectively (100%), referring explicitly to others' messages interactively (56.6%) and for greetings (phatic and salutation) cohesively (61.8%). Qualitative themes indicate that all three categories of social presence theory communications were present sufficiently with interactive category being the most common, as members used the WhatsApp platform to interact, construct and share knowledge. Group WhatsApp platform is a veritable means of communication and an indicator of level of social presence among Nigerian physiotherapists. Communication among Nigerian physiotherapists is mostly interactive, then cohesive and affective in terms of dynamics.

Influence of well-being and quality of work-life on quality of care among healthcare professionals in southwest, Nigeria

The Nigerian healthcare industry is bedevilled with infrastructural dilapidations and a dysfunctional healthcare system. This study investigated the influence of healthcare professionals' well-being and quality of work-life (QoWL) on the quality of care (QoC) of patients in Nigeria. A multicentre cross-sectional study was conducted at four tertiary healthcare institutions in southwest, Nigeria. Participants' demographic information, well-being, quality of life (QoL), QoWL, and QoC were obtained using four standardised questionnaires. Data were summarised using descriptive statistics. Inferential statistics included Chi-square, Pearson's correlation, independent samples t-test, confirmatory factor analyses and structural equation model. Medical practitioners (n = 609) and nurses (n = 570) constituted 74.6% of all the healthcare professionals with physiotherapists, pharmacists, and medical laboratory scientists constituting 25.4%. The mean (SD) participants' well-being = 71.65% (14.65), QoL = 61.8% (21.31), QoWL = 65.73% (10.52) and QoC = 70.14% (12.77). Participants' QoL had a significant negative correlation with QoC while well-being and quality of work-life had a significant positive correlation with QoC. We concluded that healthcare professionals' well-being and QoWL are important factors that influence the QoC rendered to patients. Healthcare policymakers in Nigeria should ensure improved work-related factors and the well-being of healthcare professionals to ensure good QoC for patients.

Nigerian physiotherapists’ knowledge, attitude, and practice of digital physical therapy: a cross-sectional study

Background

The increasing demand for physical therapy services worldwide calls for innovations to be made to meet the challenges of service delivery. However, little is known about the knowledge, attitude, and practice (KAP) of digital physical therapy among Nigerian physiotherapists. Hence, this study aimed to evaluate the level of KAP of digital physical therapy among physiotherapists in Nigeria.

Methods

This cross-sectional study purposively recruited 150 Nigerian physiotherapists. Copies of modified and validated questionnaires on the KAP of digital physical therapy from a previous study were sent to registered and licensed physiotherapists via electronic survey to assess the KAP of digital physical therapy. Descriptive and inferential statistics were used to analyze the data. Alpha level was set at p < 0.05.

Results

The mean age of the respondents was 29.76 ± 6.95 years. Most participants (81.3%) have a knowledge level above average, while 18.7% have below average. Furthermore, most (76.0%) of the respondents had a positive attitude toward digital physical therapy. In addition, more than two-thirds, 69.3% uses digital physical therapy platforms for physical therapy practice. Knowledge, attitude, and practice were not significantly associated with sociodemographic characteristics (p > 0.05). Furthermore, there was no significant association between knowledge, attitude, and practice (p > 0.05).

Conclusion

Many Nigerian physiotherapists demonstrated adequate knowledge, positive attitude, and good practice of digital physical therapy. However, knowledge, attitude, and practice of digital physical therapy were not influenced by sociodemographic characteristics.

Pattern and perception of wellbeing, quality of work life and quality of care of health professionals in Southwest Nigeria

BACKGROUND

Personal wellbeing (PW) including quality of life and work life is a very complex concept that influences health professionals' commitment and productivity. Improving PW may result in positive outcomes and good quality of care. Therefore, this study aimed to assess the pattern and perception of wellbeing, quality of work life (QoWL) and quality of care (QoC) of health professionals (HPs) in southwest Nigeria.  METHODS: The study was a convergent parallel mixed method design comprising a cross-sectional survey (1580 conveniently selected participants) and a focus group interview (40 purposively selected participants). Participants' PW, quality of life (QoL), QoWL, and QoC were assessed using the PW Index Scale, 5-item World Health Organization Well-Being Index, QoWL questionnaire, and Clinician QoC scale, respectively. The pattern of wellbeing, QoWL and quality of care of HPs were evaluated using t-test and ANOVA tests. Binary regression analysis was used to assess factors that could classify participants as having good or poor wellbeing, QoWL, and quality of care of HPs. The qualitative findings were thematically analyzed following two independent transcriptions. An inductive approach to naming themes was used. Codes were assigned to the data and common codes were grouped into categories, leading to themes and subthemes.

RESULTS

Of 1600 administered questionnaires, 1580 were returned, giving a 98.75% response rate. Only 45.3%, 43.9%, 39.8% and 38.4% of HP reported good PW, QoL, QoC and QoWL, respectively; while 54.7%, 56.1%, 60.2% and 61.6% were poor. There were significant gender differences in PW and QoC in favor of females. With an increase in age and years of practice, there was a significant increase in PW, QoWL and QoC. As the work volume increased, there was significant decrease in QoWL. Participants with master's or Ph.D. degrees reported improved QoWL while those with diploma reported better QoC. PWI and QoC were significantly different along the type of appointment, with those who held part-time appointments having the least values. The regression models showed that participant's characteristics such as age, gender, designation, and work volume significantly classified health professionals who had good or poor QoC, QoWL, PW and QoL. The focus group interview revealed four themes and 16 sub-themes. The four themes were the definitions of QoC, QoWL, and PW, and dimensions of QoC.

CONCLUSION

More than half of health professionals reported poor quality of work life, quality of life and personal wellbeing which were influenced by personal and work-related factors. All these may have influenced the poor quality of care reported, despite the finding of a good knowledge of what quality of care entails.

Prevalence and pattern of work-related musculoskeletal disorders among Nigerian bricklayers

BACKGROUND: Typically, bricklayers in developing countries’ contexts manually lay bricks, concrete blocks and other similar materials to construct walls and buildings which make them susceptible to work-related musculoskeletal disorders (WRMSDs). The burden of WRMSDs among this high-risk group seems has not been well documented. OBJECTIVES: This study examined the prevalence of WRMSDs among bricklayers in Nigeria. METHODS: A cross-sectional survey of 118 consenting bricklayers from a Nigerian setting was carried out. The standardized Nordic musculoskeletal disorder questionnaire and a proforma were used to profile the prevalence of WRMSDs and socio-demographic information of the respondents. Data was analyzed using descriptive and inferential statistics. Alpha level was set at p < 0.05. RESULTS: The 12-months and 7-days prevalence of WRMSDs were 87.3% and 67.4%. Shoulder (61.0%) and the low-back (59.3%) were the two most affected anatomical sites based on 12-month prevalence. WRMSDs affecting the knees (6.8%) was the most disabling in carrying normal work routines. Working for less than 10 years was significantly associated with high prevalence of WRMSDs in the shoulder (odd ratio (OR) = 0.27, 95% confidence interval (CI) = 0.09 to 0.87) and wrist region (OR = 0.24, 95% CI 0.08 to 0.73). Having neck pain led to higher odds (OR = 0.29, 95% CI 0.13 to 0.68) of taking a break from work among the bricklayers. CONCLUSIONS: WRMSDs were high among Nigerian bricklayers. Years of work experience was associated with high prevalence of WRMSDs in the shoulder and wrist. In addition, taking work breaks was associated with neck pain.

Patients' satisfaction with physiotherapy management of chronic mechanical neck pain in physiotherapy departments of public hospitals in Ibadan, Nigeria: A mixed-method study

INTRODUCTION

The study was aimed at determining patients' satisfaction level with physiotherapy in the management of chronic mechanical neck pain (CMNP) in physiotherapy departments of the 3 public hospitals in Ibadan, Nigeria.

METHODS

A mixed-method design that involved 51 and five both purposively selected participants for the cross-sectional survey (CSS) and qualitative study, respectively. For the CSS, data was collected using the MedRisk instrument and analyzed using the Chi-square test at p ≤ .05. For the qualitative study, patients' satisfaction was explored through a focus group discussion (FGD) and analyzed using thematic analysis.

RESULTS

For CSS, 49.0% and 7.8% of the participants reported excellent and fair satisfaction, respectively, with physiotherapy in the management of CMNP. There was no significant association of patients' satisfaction level with: age (p = .588); sex (p = .851); and marital status (p = .409). For the FGD, three themes (patients' experience with physiotherapists; patient satisfaction with physiotherapy services; patient satisfaction with other health care services) that emerged further explained that participants were satisfied with physiotherapy management of their CMNP. However, they were not satisfied with the attitude of the record officers, constancy of the same treating physiotherapists, and unavailability of resources.

CONCLUSION

Patients with CMNP are satisfied with the physiotherapy care they received.

Cultural adaptation and psychometric evaluation of the Yoruba version of the Health Literacy Questionnaire

Background

Health literacy is an important multidimensional concept of public health concern and a determinant of health outcomes and access to healthcare which requires robust measurement. The objective of this study was to culturally adapt and establish the psychometric properties of the Yoruba version of the Health Literacy Questionnaire.

Methods

A cross-sectional survey of Nigeria Yoruba speaking adults was conducted with the Health Literacy Questionnaire following its translation and adaptation. Data were subject to psychometric evaluation (confirmatory factor analysis, composite reliability, Cronbach's alpha, intra class correlation) and association with sociodemographic variables.

Results

A total of 258 adults with mean age 26.7 years participated in the study. The easiest scale to score highly was 'Actively managing my health' and hardest was 'Ability to find good health information' and 'Navigating the healthcare system'. Six one-factor models fitted well without correlated residuals but the other three had a good fit after model modification. Composite reliability and Cronbach's α of ≥ 0.7 were observed for all scales, suggesting good internal consistency of the scales. Test-retest reliability of the Yoruba translation of the Health Literacy Questionnaire was moderate to good in all scales, intra class correlation ranging from 0.66 to 0.76.

Conclusion

The Health Literacy Questionnaire was successfully translated and culturally adapted and demonstrated good content and construct validity and high composite reliability. The Yoruba translation of the Health Literacy Questionnaire has the potential of being a useful clinical tool for the assessment of health literacy, especially among Yoruba speaking community of Nigeria. Thereby helping to improve the health outcomes through access to healthcare.

Factors associated with fatigue in hip and/or knee osteoarthritis: a systematic review and best evidence synthesis

Objective

The aim was systematically to identify and evaluate factors related to fatigue in individuals with hip and/or knee OA.

Methods

A systematic literature search was conducted using AMED, CINAHL, MEDLINE, ProQuest and Web of Science Core Collections databases. Inclusion criteria comprised cross-sectional, case–control or longitudinal studies on patients with a diagnosis of hip and/or knee OA that included self-reported fatigue measures. Study quality was assessed using the National Heart, Lung and Blood Institute quality appraisal tool, and factors were synthesized within a bio-behavioural framework. Study designs and quality were combined to determine current evidence levels using best evidence synthesis grading. The full review protocol is available from PROSPERO (PROSPERO 2019: CRD42019138571).

Results

Twenty-four studies were included, of which 19 were high, 4 moderate and 1 low quality. There was strong evidence of an association between poor self-reported physical function and high depressive symptoms with higher fatigue. Moderate evidence of an association was found between severe pain, high numbers of co-morbidities and low physical activity levels with higher fatigue. There was moderate or limited evidence of no association between most sociodemographic factors and radiographic OA severity with fatigue.

Conclusion

Targets for fatigue management might include improving physical function, reducing depressive symptoms, pain and co-morbidities, and increasing physical activity levels. There is a need for more rigorous longitudinal studies to understand the causal effect of fatigue determinants within the hip and knee OA populations.

Development and Feasibility Testing of Video Home Based Telerehabilitation for Stroke Survivors in Resource Limited Settings

Tele-physiotherapy has been shown to be valuable to improve clinical outcomes after stroke. Yet, home-based interventions for stroke survivors (SSVs) who speak indigenous African languages are sparse. This study developed a video-based home exercise programme (VHEP) for SSV speakers of Yoruba. A qualitative descriptive pilot study was conducted in two phases: development and feasibility testing. VHEP development followed the American Stroke Association's recommendations to include demonstrations of task-specific mobility-task and postural training; trunk exercises, and overground walking. The exercise instructions were presented in the Yoruba language. Each exercise was demonstrated for five minutes on video for a total of 30 minutes. The feasibility testing involved ten consenting chronic SSVs. Each imitated the VHEP twice per week for two weeks and thereafter completed a feasibility questionnaire. Criteria for feasibility were: cost of using VHEP, recruitment rate, retention of participants, adherence to the exercises, and intervention delivery. The ten SSVs were recruited within one week, had prior home access to a video player at no-cost, adhered to the exercises as recorded, completed the 30 minute-duration for two weeks, and confirmed intervention delivery of VHEP. Most participants liked the novel use of Yoruba as the language of instruction on VHEP. The VHEP was feasible and acceptable among the studied sample of SSVs. Video based home telerehabilitation for SSVs therefore has the potential to meet the growing need for tele-physiotherapy in resource limited settings.

The Clinical and Cost-Effectiveness of Telerehabilitation for People With Nonspecific Chronic Low Back Pain: Randomized Controlled Trial

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.

Cross-cultural adaptation and psychometric evaluation of the Yoruba version of the Back beliefs questionnaire among patients with chronic low-back pain

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 forward-backward 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, test-retest 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 test-retest 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.

Comparative Efficacy of Clinic-Based and Telerehabilitation Application of Mckenzie Therapy in Chronic Low-Back Pain

Studies on validation of telerehabilitation as an effective platform to help manage as well as reduce burden of care for Low-Back Pain (LBP) are sparse. This study compared the effects of Telerehabilitation-Based McKenzie Therapy (TBMT) and Clinic-Based McKenzie Therapy (CBMT) among patients with LBP. Forty-seven consenting patients with chronic LBP who demonstrated 'directional preference' for McKenzie Extension Protocol (MEP) completed this quasi experimental study. The participants were assigned into either the CBMT or TBMT group using block permuted randomization. Participants in the CBMT and TBMT groups received MEP involving a specific sequence of lumbosacral repeated movements in extension aimed to centralize, decrease, or abolish symptoms, thrice weekly for eight weeks. TBMT is a comparable version of CBMT performed in the home with the assistance of a mobile phone app. Outcomes were assessed at the 4th and 8th weeks of the study in terms of Pain Intensity (PI), Back Extensors Muscles' Endurance (BEME), Activity Limitation (AL), Participation Restriction (PR), and General Health Status (GHS). Data were analyzed using descriptive and inferential statistics. Alpha level was set at p< 0.05. Within-group comparison across baseline, 4^th and 8^th weeks indicate that both CBMT and TBMT had significant effects on PI (p=0.001), BEME (p=0.001), AL (p=0.001), PR (p=0.001) and GHS (p=0.001) respectively. However, there were no significant differences (p>0.05) in the treatment effects between TBMT and CBMT, except for 'vitality' (p=0.011) scale in the GHS where TBMT led to significantly higher mean score. Mobile-app platform of the McKenzie extension protocol has comparable clinical outcomes with the traditional clinic-based McKenzie Therapy, and thus is an effective supplementary platform for care of patients with low-back pain.

Comparative effects of burst mode alternating current and resisted exercise on physical function, pain intensity and quadriceps strength among patients with primary knee osteoarthritis

Background and objective: The benefi cial effect of Resisted Exercise (RE) in Knee Osteoarthritis (OA) rehabilitation is often hamstrung by the presence of other comorbidities affecting exercise implementation, hence the need for comparative alternative therapies. This study compared the effect of Burst Mode Alternating Current (BMAC) and RE in the management of patients with knee OA. Methods: Forty-seven consenting patients with primary knee OA participated in this study. The participants were recruited from the outpatient physiotherapy department of a Nigerian teaching hospital. The participants were randomly assigned into either RE plus BMAC (RBMAC) or RE Only (REO) groups. The effects of intervention were assessed in terms of physical function, pain intensity and quadriceps strength at the 4th and 8th week of intervention. Descriptive and inferential statistics were used to analyze data at p<0.05 alpha level. Result: RBMAC and REO led to signifi cant mean changes in physical function (RBMAC – p=0.001: REO – p=0.001), pain intensity (RBMAC − p=0.001: REO – p=0.001), and muscle strength (RBMAC − p=0.001: REO – p=0.001) scores. However, there was no signifi cant difference in the mean change in physical function, pain intensity or muscle strength scores between RE plus BMAC and RE only groups (p>0.05). Conclusion: In conclusion, resisted exercise alone had signifi cant effects on physical function, pain intensity and quadriceps strength in patients with knee osteoarthritis. However, burst mode alternating current did not show additional effects.

Self-reported physical activity versus physical function capacity: alternatives for energy expenditure estimation

The extent to which self-report activity measured by the International Physical Activity Questionnaire (IPAQ) can substitute performance-based functional capacity measured by the Six-Minute Walk Test (6MWT) remains inconclusive. This study assessed Physical Activity (PA) and Functional Exercise Capacity (FEC); and also determined the relationship between PA and FEC in apparently healthy young adults. A total of 342 (145 males and 197 females) undergraduates of Obafemi Awolowo University, Ile-Ile, Nigeria participated in the study. The IPAQ was used to assess PA, while FEC was assessed using the 6MWT, and expressed in terms of the Six-Minute Walk Distance (6MWD), Six-Minute Walk Work (6MWW), Maximum Oxygen Uptake (VO2max) and Metabolic Equivalent (METS). Anthropometric and cardiovascular parameters were measured following standardized procedures. Data was analyzed using descriptive and inferential statistics. The alpha level was set at 0.05. The mean age of the participants was 22.0±2.87 years. The mean IPAQ score of all participants was 1471.4±1086.93. The percentage for low, moderate and high PA was 19% (65), 41.2% (141) and 39.8% (136), respectively. The mean 6MWD, 6MWW, VO2max and METS were 639.47 ±66.6 m, 41805.0 ±8520.6 kg·m, 28.9 ±1.92 mlO2k-1min-1, 4.05 ±0.32 mL/kg, respectively. There were signifi cant positive correlations between PA and each of the 6MWD (r=0.268; p=0.001), 6MWW (r=0.219; p=0.001), VO2max (r=0.268; p=0.001), METS (r=0.268; p=0.001). Measures of exercise capacity were not signifi cantly correlated with the anthropometric variables (p>0.05).

Effective non-drug interventions for improving outcomes and quality of maternal health care in sub-Saharan Africa: a systematic review

BACKGROUND

Many interventions have been implemented to improve maternal health outcomes in sub-Saharan Africa (SSA). Currently, however, systematic information on the effectiveness of these interventions remains scarce. We conducted a systematic review of published evidence on non-drug interventions that reported effectiveness in improving outcomes and quality of care in maternal health in SSA.

METHODS

African Journals Online, Bioline, MEDLINE, Ovid, Science Direct, and Scopus databases were searched for studies published in English between 2000 and 2015 and reporting on the effectiveness of interventions to improve quality and outcomes of maternal health care in SSA. Articles focusing on interventions that involved drug treatments, medications, or therapies were excluded. We present a narrative synthesis of the reported impact of these interventions on maternal morbidity and mortality outcomes as well as on other dimensions of the quality of maternal health care (as defined by the Institute of Medicine 2001 to comprise safety, effectiveness, efficiency, timeliness, patient centeredness, and equitability).

RESULTS

Seventy-three studies were included in this review. Non-drug interventions that directly or indirectly improved quality of maternal health and morbidity and mortality outcomes in SSA assumed a variety of forms including mobile and electronic health, financial incentives on the demand and supply side, facility-based clinical audits and maternal death reviews, health systems strengthening interventions, community mobilization and/or peer-based programs, home-based visits, counseling and health educational and promotional programs conducted by health care providers, transportation and/or communication and referrals for emergency obstetric care, prevention of mother-to-child transmission of HIV, and task shifting interventions. There was a preponderance of single facility and community-based studies whose effectiveness was difficult to assess.

CONCLUSIONS

Many non-drug interventions have been implemented to improve maternal health care in SSA. These interventions have largely been health facility and/or community based. While the evidence on the effectiveness of interventions to improve maternal health is varied, study findings underscore the importance of implementing comprehensive interventions that strengthen different components of the health care systems, both in the community and at the health facilities, coupled with a supportive policy environment.

Knowledge, attitude and techniques of breastfeeding among Nigerian mothers from a semi-urban community

BACKGROUND

Mothers' poor knowledge and negative attitude towards breastfeeding may influence practices and constitute barriers to optimizing the benefits of the baby-friendly initiative. This study assessed breastfeeding knowledge, attitude and techniques of postures, positioning, hold practice and latch-on among Nigerian mothers from a Semi-Urban community.

METHODS

Three hundred and eighty three consenting lactating mothers who have breastfed for 6 months and up to two years volunteered for this cross-sectional survey, yielding a response rate of 95.7%. A self-administered questionnaire that sought information on maternal socio-demographic variables, knowledge, attitudes and breastfeeding techniques of mothers was employed.

RESULTS

Based on cumulative breastfeeding knowledge and attitude scores, 71.3% of the respondents had good knowledge while 54.0% had positive attitude. Seventy one point three percent practiced advisable breastfeeding posture. Sitting on a chair to breastfeed was common (62.4%); and comfort of mother/baby (60.8%) and convenience (29.5%) were the main reasons for adopting breastfeeding positions. Cross-cradle hold (80.4%), football hold technique (13.3%), breast-to-baby (18.0%) and baby-to-breast latch-on (41.3%) were the common breastfeeding techniques. A majority of the respondents (75.7%) agreed that neck flexion, slight back flexion, arm support with pillow and foot rest was essential during breastfeeding. There was no significant association between breastfeeding posture practice and each of cumulative breastfeeding knowledge score levels (X2 = 0.044; p = 0.834) and attitude score levels (X2 = 0.700; p = 0.403).

CONCLUSION

Nigerian mothers demonstrated good knowledge and positive attitude towards breastfeeding. Most of the mothers practiced advisable breastfeeding postures, preferred sitting on a chair to breastfeed and utilized cross-cradle hold and baby-to-breast latch-on.

STATIC ENDURANCE OF THE BACK EXTENSOR MUSCLES: ASSOCIATION BETWEEN PERFORMANCE AND REPORTED REASONS FOR TEST TERMINATION

Purpose: Quite a few studies have reported previously on reasons for terminating tests of back muscles endurance. This study investigated the association between endurance performance and reported reasons for terminating back extensor muscle endurance test in apparently healthy adults. Methods: Three-hundred-and-seventy-six volunteers with the mean age of 38.9 ± 13.5 years participated in this study. All participants underwent modified Biering–Sørensen test of Static Muscular Endurance. Descriptive statistics of mean and standard deviation, Pearson's correlation and Chi-square, ANOVA and ANCOVA were used to analyze the data. The α level was set at 0.05. Results: It is found that 76.1% of the participants terminated the test due to fatigue in the low back, followed by low-back pain (LBP) (12.8%) and fatigue in the gluteal or hamstring muscles (7.4%) respectively. The magnitudes of the endurance time for each reason of termination — fatigue in the low back (121 ± 49.3 sec), fatigue in the gluteal or hamstring muscles (102 ± 44.0 sec), LBP (59 ± 27.4 sec), and behavioral factors (92 ± 34.7 sec) were found to be significantly different (p = 0.001). Test termination due to fatigue in the low back was on the average 62 seconds longer than that due to LBP. Conclusions: Fatigue was the most commonly reported reason for back extensor muscles' endurance test termination. Endurance time was least in those individuals who terminate the test due to complaints of LBP and greatest in those who end the task for fatigue only.

Endurance of low back musculature: normative data for adults

BACKGROUND AND OBJECTIVE

Lack of baseline values is a limitation in the quantification of physical performance testing of the low back muscles. The purpose of this study is to present an age and gender normative values for static back extensor muscles' endurance in adults.

SUBJECTS AND METHODS

Five hundred and sixty one healthy adults aged between 19 to 67 years volunteered for this study. Endurance of the low back musculature was assessed using modified Biering-Sørensen test of Static Muscular Endurance. The mean, standard deviation, and percentile scores for endurance time were determined for five gender / age groups classified on a range of 10 years.

RESULTS

The mean endurance time of all the participants was 113 ± 46 seconds. Men had higher mean endurance than women (t=3.309; p=0.001). Significant difference (F=32.702; p=0.001) was found in the endurance time across the age groups. There was an age and gender variation in the percentile values. The normative values demonstrate that a decrease in endurance time is expected with increasing age. The significant age and anthropometric differences across the age groups could contribute to the endurance differences.

CONCLUSION

These values could be used to compare a patient's score at intake and also serve as clinical target for which subsequent testing after treatment, at discharge and/or follow up can be compared, providing an indication of change in endurance capacity over time.

Quality of life and its correlates in caregivers of stroke survivors from a Nigerian population

PURPOSE

The study aimed at determining the quality of life (QOL) of caregivers of stroke survivors in a Nigeria population and some patient and caregiver-related variables that may be associated with it.

METHOD

A survey of the QOL of volunteering informal caregivers of stroke survivors in purposively selected tertiary health centres from South-Eastern Nigeria was done using the SF-12 questionnaire.

RESULT

Caregivers rated their QOL fairly well. Older age, female gender and closeness in relationship to survivor were caregivers' variables that were significantly related to poorer QOL scores. Being a woman close relative is associated with lower mental health scores while being an older close relative contributed to lower physical health score (P < 0.05). Caregivers' scores on the physical and mental health domains correlated moderately with each other (r = 0.52) and highly with their overall QOL scores (r = 0.81 and 0.88).

CONCLUSION

Caring for stroke survivors in Nigeria seems to have adverse effects on the QOL of closer relatives who are either women or older. There is a need for clinicians to help those caregivers at risk find ways of improving and optimizing their QOL.

Isometric endurance of the back extensors in school-aged adolescents with and without low back pain

BACKGROUND AND OBJECTIVE

Studies on back extensor endurance in adolescents are scarce. This study sought to establish reference data and pattern of back extensor endurance in school-aged adolescents with and without low-back pain (LBP) from Nigeria.

SUBJECTS AND METHODS

This study recruited 625 adolescents aged 11 to 19 years from eight randomly selected secondary schools. The modified Biering-Sørensen test of Static Muscular Endurance (BSME) was used to assess isometric endurance of the back extensors. Demographic and anthropometric data were collected. A modified LBP questionnaire was used to assess the presence of LBP. Descriptive and inferential analyses were used to analyze data. Significance was set at 0.05 alpha-level.

RESULTS

The mean isometric holding time (IHT) of all the participants was 132.9 $\pm$ 65.6. Males had significantly higher significant (p=0.026) IHT than females. Adolescents without LBP had a higher significant IHT (p=0.042) than those with reported history of previous LBP and those with present LBP (p=0.000) respectively. Using percentile values, poor endurance was defined as IHT that is < 90.0 s and < 67 s for males and females respectively; medium endurance was defined as IHT that ranged between 90 and 193 s and 67 and 170 s for males and females respectively while good endurance was defined as IHT that is > 193 s and > 170 s for males and females respectively. IHT was significantly related to each of body mass index, hip circumference and waist-to-hip ratio (p < 0.05).

CONCLUSION

Isometric back extensors endurance in Nigerian adolescents was comparable to the original Biering-Sørensen mean value. Majority of the participants had medium endurance performance with the back endurance pattern in the ratio 1:2:1. Male had higher isometric back extensors endurance than females. Decreased isometric back extensors endurance was associated with the presence of LBP in adolescents.

Work-related musculoskeletal disorders among nurses in Ibadan, South-west Nigeria: a cross-sectional survey

Background

Musculoskeletal disorders represent a significant occupational problem among nurses; however, data on musculoskeletal health of nurses in Sub-Sahara Africa are sparse. This study sought to determine the lifetime, 12-months period and point prevalence of work-related musculoskeletal disorders (WMSDs); the associated job risk factors and the coping strategies toward reducing the risk among nurses from selected hospitals in Ibadan, South-west Nigeria

Methods

A previously validated self administered questionnaire which sought information on demographics, prevalence and pattern of WMSDs, associated job risk factors and coping strategies was employed as the survey instrument. A total of 160 questionnaires were distributed to nurses in the different hospitals but 128 questionnaires were returned yielding an 80% response rate. 10 of the returned questionnaires were excluded because of incomplete data.

Results

Eighty-four point four percent of the nurses have had WMSDs once or more in their occupational lives. The 12-months period and point prevalence rate of WMSDs at any body region was 78% and 66.1% respectively. WMSDs occurred mostly in low back (44.1%), neck (28.0%), and knees (22.4%). 30.3% treated themselves or had visited other health practitioners for care. Nurses with > 20 years of clinical experience are about 4 times more likely to develop WMSDs (OR 3.81; CI 1.08-13.4) than those with 11-20 years experience. Working in the same positions for long periods (55.1%), lifting or transferring dependent patients (50.8%) and treating an excessive number of patients in one day (44.9%) were the most perceived job risk factors for WMSDs. Getting help in handling heavy patients (50.4%), modification of nursing procedures in order to avoid re-injury (45.4%), and modifying patient's/nurse position (40.3%) were the top three coping strategies.

Conclusions

A high proportion of Nigerian nurses reported WMSDs at some body site in their occupational lives with the low back being injured most often. Education programmes on prevention and coping strategies for musculoskeletal disorders are recommended for nurses in order to reduce the rate of occupational hazards and also promote efficiency in patient care.

Socioeconomic status and obesity among semi-urban Nigerians

OBJECTIVE

The relation between socioeconomic status (SES) and obesity in Sub-Saharan Africa (SSA) has been inconsistent.

METHODS

This study examined the prevalence of obesity and SES/obesity relations in 1,067 adults aged 30-60 years from a semi-urban Nigerian population. A structured questionnaire validated by a pictorial selfrating ladder was used to determine the participants' SES.

RESULTS

SES was found to be inversely related (p < 0.010) to weight and BMI, respectively. The odds ratio (OR) and 95% confidence interval (CI) for obesity among lower SES individuals were OR 2.4 and CI 1.91-2.88 compared with OR 2.9 and CI 2.42-3.39 in those of the middle and higher socioeconomic strata. Among males, the OR and 95% CI for obesity among lower SES individuals were OR 1.9 and CI 1.21-2.59 compared with OR 1.7 and CI 1.00-2.39 in those of the middle and higher socioeconomic strata. Among females, the OR and 95% CI for obesity among lower SES individuals were OR 3.0 and CI 2.32-3.68 compared with OR 4.7 and CI 4.02-5.38 in those of the middle and higher socioeconomic strata.

CONCLUSION

SES was inversely associated with the risk of obesity, with a higher prevalence of obesity in the lower socioeconomic stratum of the semi-urban Nigerian population.

Prevalence and pattern of hypertension in a semiurban community in Nigeria

BACKGROUND

Hypertension has been reported to be a major problem of the blacks. There is a paucity of studies, however, on community-based surveys on the prevalence and pattern of hypertension in Nigeria in the recent time. This study sought to investigate the prevalence and pattern of hypertension in the adult population living in the ancient semiurban community of Ile-Ife, southwest Nigeria.

DESIGN AND METHODS

Two thousand and ninety-seven adults of above 20 years of age were recruited into the door-to-door survey through a multistage cluster sampling technique. Diagnosis of hypertension was based on blood pressure (BP) threshold of 160/95 mmHg and the World Health Organization /International Society of Hypertension guidelines (Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure guidelines) definitions. Resting blood pressure was taken using electronic sphygmomanometer.

RESULTS

The mean age and BP of the participants were aged 44.2 +/- 11.6 years and 127/77 mmHg, respectively. The participants (36.6%) had a BP of greater than or equal to 140/90 mmHg whereas 13.3% had BP of greater than or equal to 160/95 mmHg. 22.1% had isolated systolic hypertension whereas 14.5% had isolated diastolic hypertension using the BP of greater than or equal to 140/90 mmHg cut off-point. Using the BP of greater than or equal to 160/95 mmHg, isolated systolic hypertension and isolated diastolic hypertension were 6.63%, respectively. A male-to-female ratio of 1.7 : 1 and 1 : 5 was observed for BP greater than or equal to 140/90 mmHg and BP greater than or equal to 160/95 mmHg, respectively. Hypertension prevalence increased across age gradient from young to old adults.

CONCLUSION

The prevalence estimates of hypertension obtained in this study was higher than those found in most earlier studies from Nigeria, other West Africa nations and for African-Americans.

Obesity prevalence in adult residents of Ile-Ife, Nigeria

BACKGROUND

Few data on obesity exist on Sub-Sahara population in Africa. This study investigated the prevalence of obesity and Body Mass Index (BMI) percentile and quartiles in accordance with sex and age in adult residents of the historic ancient semi-urban community of Ile-Ife, South-West, Nigeria.

METHODS

2097 adults aged 21 years and above were recruited into the door-to-door survey through a multistage cluster sampling technique. The World Health Organization (WHO) criteria based on BMI was used in the definition of overweight and obesity. Height and weight were measured using standardized procedures.

RESULTS

The mean age and BMI of the participants were 44.2 years and 24.2 Kg/m2 respectively. Although age-matched; the females had higher BMI values compared to males (23.8 vs. 24.5 Kg/m2). The overall crude prevalence of overweight (25.0-29.9 Kg/m2) and obesity (>30 Kg/m2) were 20.3% and 12.5% respectively. The rates of overweight (17.9 vs. 22.1 Kg/m2) and obesity (9.7 vs. 14.5 Kg/m2) were both higher in women than men. Obesity increased across age gradient from young to old adults; peaking in the 60-69-year age group. The first to fourth BMI quartiles were = 20.4 Kg/m2, 20.5-24.1 Kg/m2, 24.2-25.2 Kg/m2, = 25.3 Kg/mr respectively in the study population. At all ages; more females (32.4%) than males (24.7%) were placed within fourth BMI quartile. The 95th percentile BMI in the study population was 33.4 Kg/m2.

CONCLUSION

Overweight and obesity are common in Nigerians, particular among females and elderly. The prevalence estimates of overweight and obesity in Nigerians is comparable with prevalence among Blacks in other populations.

Relationship of anthropometric indicators with blood pressure levels and the risk of hypertension in Nigerian adults

BACKGROUND AND PURPOSE

Studies on cardiovascular risks in relation to anthropometric factors are limited in Sub-Sahara Africa. The aims of this study were to examine the relationship between anthropometric parameters and blood pressure; and to evaluate body mass index (BMI) across the range of underweight and obesity as a primary risk factor of hypertension in adult Nigerians.

MATERIAL AND METHODS

2097 adults aged between 20 and 100 years consented and participated in this door-to-door survey. All participants underwent blood pressure and anthropometric measurements using standard procedures. The population study was separated in normotensive and hypertensive males and females and the possible risk for hypertension were categorized into different classes of value based on BMI definition.

RESULTS

The relative risks (odds ratio [OR] and 95% confidence interval [CI]) of developing hypertension among the obese compared with the underweight, normal weight, and overweight persons were (OR 5.75; CI 5.67-5.83), (OR 1.73; CI 1.65-1.81), and (OR 1.54; CI 1.46-1.62) for all the participants, respectively. Among obese (BMI >/= 30.0 Kg/m(2)) males, the OR for hypertension was three times (OR 2.78; CI 2.76-2.80) that of normal weight (BMI >/= 18.5-24.9 Kg/m(2)) males. Females with obesity had a risk of hypertension three times (OR 3.34; CI 3.33-3.35) that of normal weight females.

CONCLUSION

Our results indicated that the there was a significant positive correlation of obesity indicator with blood pressure. In Nigeria, we found a strong gradient between higher BMI and increased risk of hypertension among all ages. Approaches to reduce the risk of hypertension may include prevention of overweight and obesity.

The influence of socio-economic status on casual blood pressures of the adult Nigerians

BACKGROUND

Studies into social inequalities in health tend to focus more on parental socio-economic status (SES) as it affects the children. We aimed to test the hypothesis that socio-economic inequalities would not affect the casual blood pressure among Nigerian adults.

METHODS AND RESULTS

Resting blood pressure (BP) and pulse rate of 1067 sedentary adults were measured. Rate pressure product and pulse pressure were later calculated. Second, a structured questionnaire, which objectively assessed the SES of the subjects, was administered. Subsequently, a self-rating SES ladder was employed to classify the subjects into different socio-economic groups. This was used as a check for the structured questionnaire. A Pearson product correlation coefficient comparing the two outcome measures revealed a high correlation (r=0.951, P<0.01). Socio-economic status was found to have an inverse significant (P<0.05) effect on systolic pressure, heart rate and pulse pressure. The 95th centile blood pressure obtained was 154/91 mmHg.

CONCLUSION

Low SES is associated with development of hypertension among the Nigerian adults.
