The Hausa Northwick Park Neck Pain Questionnaire: translation, cross-cultural adaptation and psychometric assessment in patients with non-specific neck pain.

PURPOSE: To translate and cross-culturally adapt the Northwick Park Neck Pain Questionnaire (NPQ) into Hausa and assess its psychometric properties. MATERIALS AND METHODS: The NPQ was translated and cross-culturally adapted into Hausa using recommended guidelines. A consecutive sample of 92 Hausa-speaking patients with non-specific neck pain recruited from three tertiary hospitals in north-western Nigeria, completed the questionnaire to assess factorial validity (using confirmatory factor analysis), convergent validity (by correlating the Hausa-NPQ with the Numerical Pain Rating Scale [NPRS]), and internal consistency (using Cronbach's α). A subsample of 50 patients completed the questionnaire again 3 days after the first administration to assess relative reliability using intraclass correlation coefficients (ICC) and absolute reliability using standard error of measurement (SEM), smallest detectable change (SDC), and 95% limits of agreement (LOA). RESULTS: The factor analysis confirmed a single-factor structure with excellent internal consistency (α = 0.94). The questionnaire showed a strong positive correlation with the NPRS (rho = 0.68). The ICC was 0.86, with SEM and SDC of 6.32 and 17.5, respectively. The LOA was - 29.3 to + 37.1 with no evidence of proportional bias. CONCLUSIONS: The Hausa-NPQ is a valid and reliable measure of disability due to neck pain.

This study describes the translation, cross-cultural adaptation, and psychometric assessment of the Hausa-NPQ in Hausa-speaking patients with non-specific neck pain.The questionnaire demonstrated adequate psychometric properties in terms of factorial and convergent validity, internal consistency, and test-retest reliability.The questionnaire will be useful in clinical and research settings to assess disability due to neck pain for screening purposes, evaluation of treatment effectiveness, as well as cross-cultural comparisons involving Hausa-speaking individuals with neck pain.

Prevalence, pattern and impact of sleep disturbance on quality of life and exercise participation among children with cerebral palsy in Kano city.

INTRODUCTION: Sleep disturbance (SD) could have negative impact on the general well-being of children with cerebral palsy (CWCP). OBJECTIVES: The purpose of this study was to assess the prevalence of SD and its impact on quality of life and exercise participation among CWCP. MATERIAL AND METHODS: In the cross-sectional study, CWCP and their siblings were recruited from secondary and tertiary hospitals in Kano City. SD, gross motor function (GMF), spasticity and quality of life were assessed with SD scale, GMF classification system, modified Ashworth scale and pediatric quality of life inventory, respectively. Data was analyzed with Mann-Whitney U and chi-square tests, linear and hierarchical regressions using SPSS version 20.0. RESULTS: There were 200 CWCP (aged 4.35±8.03 years) and 200 siblings (aged 5.89±3.06 years). The prevalence of SD in CWCP was 31.5%. CWCP suffered more SD than their siblings (p<0.001). SD in CWCP is influenced by GMF level (ß=0.378, p<0.001) and gender (ß=0.16, p<0.05). SD has negative influence on quality of life (ß=-0.18, p<0.001), active participation in home-based (ß=-0.23, p<0.000), and clinic-based exercises (ß=-0.24, p<0.00). GMF levels (ß=-0.505, p<0.0001), hamstring spasticity (ß=-0.250, p<0.005), and age (ß=-0.207, p<0.001) also have influenced on quality of life. CONCLUSION: One-third of the CWCP suffered pathologic SD, which has negative impact on their quality of life and the ability to actively participate in both home and clinic-based exercises. Aside SD, other factors such as child's age, spasticity level and severity of motor impairment also affected their quality of life negatively. Enhancing the motor abilities of CWCP may improve their quality of sleep and quality of life.

Analysis of Direct Monthly Cost of Outpatient Hospital-Based Care for Children With Cerebral Palsy in Kano, Nigeria.

BACKGROUND: Children with cerebral palsy require effective, accessible and affordable medical and rehabilitation care. OBJECTIVE: The aim of this study was to evaluate the direct monthly cost of outpatient hospital-based care for children with cerebral palsy (CP) in Kano City, Nigeria. METHODS: The study was a cross-sectional survey. Consenting participants were recruited using the purposive sampling technique. Data on cost of medical and physiotherapy consultations, number of consultations per month, cost of diagnostic investigations, and out-of-pocket expenditures were captured using a researcher-designed questionnaire. Data were analyzed with descriptive statistics using Microsoft Excel and SPSS version 20. RESULTS: A total of 106 children with CP and their caregivers participated in this study. The mean age of the children was 3.18 ± 1.90 years and that of their caregivers was 27.32 ± 4.63 years. The average direct cost of outpatient care per month was ₦14 295.38 (Nigerian naira) ($46.87) ± ₦13 211.52 ($43.32). The average monthly cost of physiotherapy was ₦503.77 ($1.65) ± ₦220.79 ($0.72), whereas those for transportation and radiological investigations were ₦1861.49 ($6.10) ± ₦1435.06 ($4.71) and ₦3771.46 ($12.37) ± ₦5135.32 ($16.84), respectively. CONCLUSION: The average direct monthly cost of providing outpatient hospital-based care for children with CP in Kano City, Nigeria may not be affordable because most of the participants earned very meager monthly incomes. The highest medical cost was incurred from radiological investigation, whereas transportation was the most important out-of-pocket cost. The Nigerian government should make a policy decision for the automatic enrollment of all children diagnosed with CP into the National Health Insurance Scheme.

Effectiveness of a structured circuit class therapy model in stroke rehabilitation: a protocol for a randomised controlled trial.

BACKGROUND: Currently, the key advocacy in neuroscientific studies for stroke rehabilitation is that therapy should be directed towards task specificity performed with multiple repetitions. Circuit Class Therapy (CCT) is well suited to accomplish multiple task-specific activities. However, while repetitive task practice is achievable with circuit class therapy, in stroke survivors repetitive activities may be affected by poor neurologic inputs to motor units, resulting in decreases in discharging rates which consequently may reduce the efficiency of muscular contraction. To accomplish multiple repetitions, stroke survivors may require augmented duration of practice. To date, no study has examined the effect of augmented duration of CCT in stroke rehabilitation, and specifically what duration of CCT is more effective in influencing functional capacity among stroke survivors. METHODS/DESIGN: Using a randomised controlled trial with blinded outcome assessment, this study is aimed at determining the effectiveness of structured augmented CCT in stroke rehabilitation. Sixty-eight stroke survivors (to be recruited from a tertiary health institution in Kano, Northwest, Nigeria) will be randomised into one of four groups: three intervention groups of differing CCT durations namely: 60 min, 90 min, and 120 minuntes respectively, and a control group. Participants will take part in an 8-week structured intensive CCT intervention. Participants will be assessed at baseline, post-intervention, and six-month follow-up for the effectiveness of the varied durations of therapy, using standardised tools. Based on the WHO-ICF model, the outcomes are body structure/function, activity limitation, and participation restriction measures. DISCUSSION: It is expected that the outcome of this study will clarify whether increasing CCT duration leads to better recovery of motor function in stroke survivors.

Correlates of Selected Indices of Physical Fitness And Duration of Incarceration among Inmates in Some Selected Nigeria Prisons.

BACKGROUND: Incarceration has been associated with reduced physical activity. However, physical inactivity is a major cause of morbidity and mortality. The aim of the present study was therefore, to evaluate the incidence and relationship between the measures of physical fitness and the duration of incarceration in of inmates in Kano-Nigeria prisons. METHOD: A cross-sectional study was done to determine the relationship between the measures of physical fitness and the duration of incarceration of inmates in Kano prisons. Subjects' physical fitness level (cardio-respiratory fitness, body mass index and waist circumference) was assessed using standardized protocols. Simple percentage, Pearson moment correlation test and student's t-test were used to analyze variables of interest. RESULT: One hundred and sixteen inmates; 108 (93.1%) males and 8 (6.9%) females participated in the study. The study revealed high (93.1%) prevalence of low cardio-respiratory fitness among inmates and significant correlation between the selected indices of physical fitness (cardio-respiratory fitness, body mass index and waist circumference) and duration of incarceration. CONCLUSION: The prevalence of low cardio-respiratory fitness was high among inmates and long period of inadequate physical activity may be implicated as causative factor of low physical fitness among inmates in Kano prison. Prison administration and staff should encourage healthy inmate behavior. Provision of adequate facilities to encourage physical activity and sports participation is highly needed.
