Assessing Participation in Stroke Survivors: Psychometric Properties of the Participation Measurement Scale (PM-Scale) Brazil.

Initial evidence supports the reliability of the Participation Measurement Scale (PM-Scale) in Brazil, but further exploration of its psychometric properties is needed for Brazilian stroke survivors. The aim of the study is to analyze the reliability, convergent validity, internal consistency, and accuracy of the PM-Scale Brazil. A methodological study involved three assessments over intervals of 7-14 days. Reliability was evaluated through the Intraclass Correlation Coefficient. Convergent validity was assessed using Spearman's correlation coefficient to evaluate the alignment of the PM-Scale Brazil with the SATIS-Stroke. Internal consistency was assessed through Cronbach's α. Accuracy was estimated by calculating the area under the receiver operating characteristic curve. The study involved 110 stroke survivors, revealing adequate intra-rater and inter-rater reliability. A significant weak correlation was observed between the PM-Scale and SATIS-Stroke. Internal consistency and accuracy were adequate. The PM-Scale Brazil demonstrates good reliability, internal consistency, and sensitivity. However, its weak correlation with SATIS-Stroke suggests limited convergent validity.

Assessing Participation in Stroke Survivors: Reliability and Validity of the PM-Scale BrazilIn our study, we looked at how well the PM-Scale Brazil works for measuring participation after stroke. We found that it gives consistent and reliable results, meaning it can be trusted. Although it is sensitive to identifying participation issues, it did not strongly agree with another measure called SATIS-Stroke. This might be because the two tools measure different things: SATIS-Stroke looks at activities and participation broadly, while the PM-Scale focuses specifically on participation.

High-intensity interval training is feasible, credible and clinically effective in the early subacute stroke stage in the low-income country of Benin.

High-intensity interval training (HIIT) has been shown to benefit stroke patients when implemented three months post-stroke. This study examined HIIT's feasibility and clinical effectiveness in the early post-stroke stage in Benin. This was a prospective interventional study comprising an HIIT programme executed on a recumbent bike, three times/week, 20-30 min/session for 6 weeks, added to a conventional physiotherapy. The primary outcomes were feasibility, credibility and expectancy assessed with credibility and expectancy questionnaire. A maximal exercise test, 6-min walking test (6MWT), 10-m walking test (10mWT), Berg balance scale (BBS) and five repetitions sit-to-stand test (5 R-STS) were performed before and after the training programme. Ten outpatients, with a median age [P25-P75]: 63.5[56.7-71.2] years; time since stroke: 15.0[9.7-21.0] days, started and completed all training sessions without serious adverse events. High scores were observed on the Credibility subscale at admission (27.0[25.7-27.0]), which remained so after intervention (26.5[25.7-27.0]). Expectancy subscale scores were high at admission (25.5[24.0-27.0]) and post-training (25.5[24.5-27.0]). Peak workload (p < 0.001), BBS (p < 0.001), 6MWT (p < 0.001), 10mWT (p < 0.001) and 5 R-STS (p = 0.004) were all improved. HIIT is feasible and safe in the early subacute post-stroke stage and is perceived by patients as highly credible, meeting their expectations of recovery.

Effectiveness of mHealth Interventions to Improve Pain Intensity and Functional Disability in Individuals With Hip or Knee Osteoarthritis: A Systematic Review and Meta-analysis.

OBJECTIVE: This review aimed to investigate the effectiveness of mHealth-supported active exercise interventions to reduce pain intensity and disability level in persons with hip or knee osteoarthritis (OA). DATA SOURCES: Three databases (PubMed, Cochrane Library, and Web of Science) were systematically searched for randomized controlled trials (RCTs) published between January 1, 2012 and July 31, 2023. PROSPERO registration number of this review was CRD42023394119. STUDY SELECTION: We included only RCTs that were identified and screened by 2 independent reviewers (J.M. and G.N.). In addition, the reference lists of the identified studies were manually checked for further inclusion. Included studies had to provide mHealth-supported active exercises for persons with hip or knee OA, and evaluate pain intensity and disability using both questionnaires and performance tests. DATA EXTRACTION: From the included studies, the 2 independent authors extracted data using a predetermined Excel form. Characteristics of the interventions were described and a meta-analysis was performed. DATA SYNTHESIS: Twelve RCTs were included, representing 1541 patients with a mean age of 58.7±5 years, and a body mass index of 28.8±3.1 kg/m2; women being more predominant than men with a total female to male ratio of 2.2. The methodological quality of the included studies was moderate in 75% of the studies. There was no statistically significant difference between mHealth-supported active exercises compared with the interventions without mHealth in terms of pain reduction (standard mean differences [SMD]=-0.42; 95% CI, -0.91 to 0.07; P=.08) and disability mitigation (SMD=-0.36; 95% CI, -0.81 to 0.09; P=.10). However, a statistically significant difference was found between patient education combined with mHealth-supported active exercises compared with patient education alone in terms of pain (SMD= -0.42; 95% CI, -0.61 to -0.22; P<.01) and disability (SMD=-0.27; 95% CI, -0.46 to -0.08; P<.01) reduction. CONCLUSIONS: mHealth-supported exercises were found to be effective, especially when combined with patient education, in reducing pain and mitigating disability in patients with hip or knee OA.

The prevalence and demographic associations of headache in the adult population of Benin: a cross-sectional population-based study.

BACKGROUND: The Global Burden of Disease (GBD) study is increasingly well informed with regard to headache disorders, but sub-Saharan Africa (SSA) remains one of the large regions of the world with limited data directly derived from population-based studies. The Global Campaign against Headache has conducted three studies in this region: Ethiopia in the east, Zambia in the south and Cameroon in Central SSA. Here we report a similar study in Benin, the first from West SSA. METHODS: We used the same methods and questionnaire, applying cluster-randomized sampling in three regions of the country, randomly selecting households in each region, visiting these unannounced and randomly selecting one adult member (aged 18-65 years) of each household. The HARDSHIP structured questionnaire, translated into Central African French, was administered face-to-face by trained interviewers. Demographic enquiry was followed by diagnostic questions based on ICHD-3 criteria. RESULTS: From 2,550 households with eligible members, we recruited 2,400 participants (participating proportion 94.1%). Headache ever was reported by almost all (95.2%), this being the lifetime prevalence. Headache in the last year was reported by 74.9%. Age-, gender- and habitation-adjusted estimates of 1-year prevalence were 72.9% for all headache, 21.2% for migraine (including definite and probable), 43.1% for TTH (also including definite and probable), 4.5% for probable medication-overuse (pMOH) and 3.1% for other headache on ≥ 15 days/month. One-day (point) prevalence of headache was 14.8% according to reported headache on the day preceding interview. CONCLUSIONS: Overall, these findings are evidence that headache disorders are very common in Benin, a low-income country. The prevalence of pMOH, well above the estimated global mean of 1-2%, is evidence that poverty is not a bar to medication overuse. The findings are very much the same as those in a similar study in its near neighbour, Cameroon. With regard to migraine, they are reasonably in accord with two of three earlier studies in selected Beninese populations, which did not take account of probable migraine. This study adds to the hitherto limited knowledge of headache in SSA.

How Low Back Pain is Managed-A Mixed-Methods Study in 32 Countries. Part 2 of Low Back Pain in Low- and Middle-Income Countries Series.

BACKGROUND: The Lancet Low Back Pain (LBP) Series highlighted the lack of LBP data from low- and middle-income countries (LMICs). The study aimed to describe (1) what LBP care is currently delivered in LMICs and (2) how that care is delivered. DESIGN: An online mixed-methods study. METHODS: A Consortium for LBP in LMICs (n = 65) was developed with an expert panel of leading LBP researchers (>2 publications on LBP) and multidisciplinary clinicians and patient partners with 5 years of clinical/lived LBP experience in LMICs. Quantitative data were analyzed using descriptive statistics. Two researchers independently analyzed qualitative data using inductive and deductive coding and developed a thematic framework. RESULTS: Forty-seven (85%) of 55 invited panel members representing 32 LMICs completed the survey (38% women, 62% men). The panel included clinicians (34%), researchers (28%), educators (6%), and people with lived experience (4%). Pharmacotherapies and electrophysiological agents were the most used LBP treatments. The thematic framework comprised 8 themes: (1) self-management is ubiquitous, (2) medicines are the cornerstone, (3) traditional therapies have a place, (4) society plays an important role, (5) imaging use is very common, (6) reliance on passive approaches, (7) social determinants influence LBP care pathway, and (8) health systems are ill-prepared to address LBP burden. CONCLUSION: LBP care in LMICs did not consistently align with the best available evidence. Findings will help research prioritization in LMICs and guide global LBP clinical guidelines.

Estimating the Prevalence of Cerebral Palsy in a Semi-Urban City in Benin: A Door-to-Door Community-Based Study.

INTRODUCTION: Cerebral palsy (CP) is the most common cause of pediatric motor disability. While epidemiological data are widespread in high-income countries, corresponding data in low-income countries in sub-Saharan Africa are still rare. This study aimed to estimate the prevalence of CP in Northern Benin, a French-speaking low-income country in sub-Saharan Africa. METHODS: This study was a community-based door-to-door study involving children younger than 18 years old, in Parakou, a semi-urban city in Benin. We used a two-stage procedure. The first one consisted on children screening to identify potential cases of CP. During the second stage, suspected children were examined by neurologists with high experience with CP. RESULTS: In total, 2,630 children were screened with 10 confirmed cases of CP, resulting in a crude prevalence (95% confidence interval) of 3.8 (1.4, 6.15) per 1,000 children. Of the 10 confirmed cases, six were younger than 5 years old, and five were male. Eight children over ten were spastic with six bilateral spastic subtype according to the Surveillance of Cerebral Palsy in Europe classification system. Seven children had a Gross Motor Function Classification System level III-V, and six were classified level III to V of the manual ability classification system. CONCLUSION: CP is highly prevalent in semi-urban area in Northern Benin. Large studies on potential risk factors are needed for the development of effective preventive strategies.

Bilateral versus unilateral upper limb training in (sub)acute stroke: A systematic and meta-analysis.

Background: Integrating high dosage bilateral movements to improve upper limb (UL) recovery after stroke is a rehabilitation strategy that could potentially improve bimanual activities. Objectives: This study aims to compare the effects of bilateral with unilateral UL training on upper limb impairments and functional independence in (sub)acute stroke. Method: Five electronic databases (PubMed, Scopus, PEDro, ScienceDirect, Web of Science) were systematically searched from inception to June 2023. Randomised controlled trials comparing the effect of bilateral training to unilateral training in stroke survivors (< 6 months poststroke) were included. The treatment effect was computed by the standard mean differences (SMDs). Results: The review included 14 studies involving 706 participants. Bilateral training yielded a significant improvement on UL impairments measured by FMA-UE compared to unilateral training (SMD = 0.48; 95% CI: 0.08 to 0.88; P = 0.02). In addition, subgroup analysis based on the severity of UL impairments reported significant results in favour of bilateral UL training in improving UL impairments compared to unilateral training in "no motor capacity" patients (SMD = 0.66; 95% CI: 0.16 to 1.15; P = 0.009). Furthermore, a significant difference was observed in favour of bilateral UL training compared to unilateral UL training on daily activities measured by Functional Independence Measure (SMD = 0.45; 0.13 to 0.78; P = 0.006). Conclusion: Bilateral UL training was superior to unilateral training in improving impairments measured by FMA-UE and functional independence in daily activities measured by Functional Independence Measure in (sub)acute stroke. Clinical implications: Bilateral upper limb training promotes recovery of impairments and daily activities in (sub)acute phase of stroke.

Relationships between cardiorespiratory fitness, physical activity practices, and functional outcomes one-year post-stroke in northern Benin: A case-control study.

BACKGROUND: Currently, little is known on the relationships between cardiorespiratory fitness (CF), physical activity (PA), and functional outcomes after stroke, especially in low- and middle-income countries. OBJECTIVES: We examine the relationships between CF, PA, and functional outcomes in one-year poststroke in Benin, a lower middle-income country. METHODS: A case-control study was carried out in northern Benin. Twenty-one participants with chronic strokes were matched to 42 controls according to sex and age. PA patterns and associated energy expenditure (EE) were assessed with a BodyMedia's senseWear armband. CF was evaluated with the Physical Working Capacity at 75% of the predicted maximal heart rate index. The functional outcomes were evaluated using the modified Rankin scale (mRS) and the ACTIVLIM-Stroke scale. RESULTS: Both people with stroke and the healthy pairs spent much time in sedentary behavior (median [P25; P75]: 672 [460; 793] min vs 515 [287; 666] min, p = 0.006). Although people with chronic stroke performed fewer steps compared to healthy controls (median: 2767 vs 5524, p = 0.005), results showed that total EE was not statistically significant in either group (median: 7166 Kcal vs 8245 Kcal, p = 0.07). In addition, the mRS score (r = 0.47, p = 0.033) and the ACTIVLIM-Stroke measure (r = 0.52, p = 0.016) were moderately associated with the CF index of people with chronic stroke. CONCLUSION: The study showed clear trends for lower levels of PA in both people with chronic stroke and health controls. A correlation exists between CF, disability, and functional outcomes among stroke patients.

Mobile technologies for rehabilitation in non-specific spinal disorders: a systematic review of the efficacy and potential for implementation in low- and middle-income countries.

PURPOSE: The aim of this systematic review was primarily to identify the types of mHealth technologies for the rehabilitation of non-specific spinal disorders, second to evaluate their efficacy, and finally to determine their applicability in LMICs. METHODS: Three databases (Scopus, PubMed, and Web of Science) were searched for randomized controlled trials and clinical trials from January 2012 until December 2022. Studies were found eligible when using mHealth technologies for the rehabilitation of non-specific spinal disorders. To evaluate efficacy, the primary outcome was pain intensity, and the secondary outcomes were disability and quality of life. To evaluate the applicability in LMICs, information about financial and geographical accessibility, offline usability, and languages was extracted. RESULTS: Fifteen studies were included comprising 1828 participants who suffer from non-specific low back pain (86.05%) and non-specific neck pain (13.95%). Fourteen distinct smartphone-based interventions and two sensor system interventions were found, with a duration ranging from four weeks to six months. All mHealth interventions demonstrated efficacy for the improvement of pain, disability and quality of life in non-specific spinal disorders, particularly low back pain. Five of the evaluated smartphone applications were free of charge accessible and had language features that could be adapted for use in LMICs. CONCLUSION: mHealth interventions can be used and integrated into the conventional treatment of non-specific spinal disorders in rehabilitation. They have demonstrated efficacy and could be implemented in LMICs with minor adaptations to overcome language barriers and the absolute necessity of the internet.

Physiotherapy practices in acute and sub-acute stroke in a low resource country: A prospective observational study in Benin.

BACKGROUND AND OBJECTIVE: Physiotherapy is highly recommended for early recovery from stroke. This study aimed to document physiotherapy practices for people with acute and early sub-acute stroke in Benin. METHODS: In this prospective observational study, physiotherapists working with acute stroke people documented the content of their treatment from six hospitals in Benin during the first session, at 2-week, and 1-month post-stroke with a standardized physiotherapy documentation form. We used the motricity index (MI) and trunk control test (TCT) to assess impairments, and the 10-meter walk test (10mWT), functional independence measure (FIM), walking, stair climbing, and dressing upper body subscales were used for activity limitations. RESULTS: Fifteen physiotherapists (60 % male, mean±SD age=31.3±5.8 years) recorded treatment sessions for 77 stroke participants (53.2 % male, mean±SD age=57.7±12.5 years). Physiotherapists focused on conventional physiotherapy approaches, including musculoskeletal (67 % of pre-functional activity time) and neuromuscular (53 % of sitting activity time) interventions. A significant difference was found between the therapy time delivered for people with mild, moderate, and severe stroke (p < 0.001). The MI (p= 0.033) and TCT (p= 0.002) measures showed significant improvement at 2-week and 1-month (p< 0.001) post-stroke, while 10mWT, FIM walking, stair climbing, and dressing upper body items significantly increased at 1-month (p< 0.001) but not at 2-week post-stroke. CONCLUSION: Physiotherapists working with acute stroke patients in Benin mainly use conventional neuromuscular and musculoskeletal interventions. In contrast, aerobic exercises were rarely employed regardless of stroke severity. Furthermore, our findings showed that the volume of physiotherapy sessions varied by stroke severity.

Exploring Communication Practices in Italian Physiotherapy: Knowledge and Use of Effective Communication Strategies-A National Descriptive Study.

This study aimed to investigate the knowledge and use of effective communication strategies among Italian physiotherapists. We utilized a questionnaire consisting of 19 questions to collect data on the knowledge and use of effective communication strategies among Italian physiotherapists. The results revealed that only 35.8% of the respondents reported being aware of communication strategies related to physiotherapy, with their first exposure occurring during their three-year degree. Despite the majority of respondents agreeing that communication is an effective strategy for improving patient adherence, only about half reported making moderate use of open-ended questions and metaphors during treatment sessions. Furthermore, more than half of the respondents reported being unaware of Motivational Interviewing. The results of this study found that there is a consensus among Italian physiotherapists about the importance of effective communication in clinical practice, though the knowledge and application of some communication strategies remain limited. These findings suggest that there is room for improvement in the training and education of physiotherapists in Italy, with a need for greater emphasis on communication strategies in the university educational curriculum, starting from the bachelor's degree.

Exercise dosage to facilitate the recovery of balance, walking, and quality of life after stroke.

Background: Although aerobic training (AT) and resistance training (RT) are recommended after stroke, the optimal dosage of these interventions and their effectiveness on balance, walking capacity, and quality of life (QoL) remain conflicting. Objectives: Our study aimed to quantify the effects of different modes, dosages and settings of exercise therapy on balance, walking capacity, and QoL in stroke survivors. Method: PubMed, CINHAL, and Hinari databases were searched for randomised controlled trials (RCTs) evaluating the effects of AT and RT on balance, walking, and QoL in stroke survivors. The treatment effect was computed by the standard mean differences (SMDs). Results: Twenty-eight trials (n = 1571 participants) were included. Aerobic training and RT interventions were ineffective on balance. Aerobic training interventions were the most effective in improving walking capacity (SMD = 0.37 [0.02, 0.71], p = 0.04). For walking, capacity, a higher dosage (duration ≥ 120 min/week; intensity ≥ 60% heart rate reserve) of AT interventions demonstrated a significantly greater effect (SMD = 0.58 [0.12, 1.04], p = 0.01). Combined AT and RT improved QoL (SMD = 0.56 [0.12, 0.98], p = 0.01). Hospital located rehabilitation setting was effective for improving walking capacity (SMD = 0.57 [0.06, 1.09], p = 0.03) compared with home and/or community and laboratory settings. Conclusion: Our findings showed that neither AT nor RT have a significant effect on balance. However, AT executed in hospital-located settings with a higher dose is a more effective strategy to facilitate walking capacity in chronic stroke. In contrast, combined AT and RT is beneficial for improving QoL. Clinical implications: A high dosage of aerobic exercise, duration ≥ 120 min/week; intensity ≥ 60% heart rate reserve is beneficial for improving walking capacity.

Translation and cross-cultural adaptation of the Brazilian version of the PM-Scale: A specific measure of participation after stroke.

BACKGROUND: The PM-Scale was developed specifically to assess participation in individuals after stroke based on the concepts contained in the International Classification of Functioning, Disability and Health. However, this measure is only available in English and French. OBJECTIVE: To translate and cross-culturally adapt the PM-Scale to Brazilian Portuguese, followed by the validation and testing of reliability of the translated version. METHODS: The translation process followed standard guidelines. Preliminary test-retest reliability was determined using the intraclass correlation coefficient (ICC2,1). The Rasch model was employed to analyse the validity, unidimensionality, invariance, and internal consistency of the Brazilian version of the PM-Scale. RESULTS: The final translated version of the PM-Scale presented appropriate semantic, idiomatic, cultural, and conceptual equivalence. The preliminary analysis revealed excellent intra-observer and inter-observer reliability (ICC2,1 = 0.91; 95%CI: 0.83, 0.95 and ICC2,1 = 0.81; 95%CI: 0.64, 0.89, respectively). The analysis of the Rasch model revealed only one erratic item. An excellent overall fit was found for items (mean ± SD = 0.01 ± 1.02) and adequate fit was found for persons (mean ± SD = 1.16 ± 0.88). Internal consistency was considered adequate (person separation index = 1.77, reliability = 0.76). No significant invariance was found with regards to the personal characteristics of the sample (p > 0.05). CONCLUSION: The Brazilian version of the PM-Scale is a valid, unidimensional, linear, reliable scale for measuring participation in stroke survivors and can be administered in less than five minutes.

Physical Activity Level, Barriers, and Facilitators for Exercise Engagement for Chronic Community-Dwelling Stroke Survivors in Low-Income Settings: A Cross-Sectional Study in Benin.

After a stroke incident, physical inactivity is common. People with stroke may perceive several barriers to performing physical activity (PA). This study aimed to document the PA level and understand the barriers and facilitators to engaging in PA for community-dwelling stroke survivors in Benin, a lower middle-income country. A cross-sectional study was conducted in three hospitals in Benin. Levels of PA were recorded by means of the Benin version of the International Physical Activity Questionnaire long form (IPAQ-LF-Benin), which is validated for stroke survivors in Benin. The perceived exercise facilitators and barriers were assessed by the Stroke Exercise Preference Inventory-13 (SEPI-13). A descriptive analysis and associations were performed with a Confidence Interval of 95% and <0.05 level of significance. A total of 87 participants (52 men, mean age of 53 ± 10 years, mean time after a stroke of 11 (IQR: 15) months and an average of 264.5 ± 178.9 m as distance on the 6 min walking test (6MWT) were included. Overall, stroke survivors in Benin reached a total PA of 985.5 (IQR: 2520) metabolic equivalent (METs)-minutes per week and were least active at work, domestic, and leisure domains with 0 MET-minutes per week. The overview of PA level showed that 52.9% of participants performed low PA intensity. However, 41.4% performed moderate PA or walking per day for at least five days per week. Important perceived barriers were lack of information (45.3%), hard-to-start exercise (39.5%), and travelling to places to exercise (29.9%). The preference for exercise was with family or friends, outdoors, for relaxation or enjoyment (90.2%), and receiving feedback (78.3%). Several socio-demographic, clinical, and community factors were significantly associated with moderate or intense PA (p < 0.05) in stroke survivors in this study. Our findings show that the PA level among chronic stroke survivors in Benin is overall too low relative to their walking capacity. Cultural factors in terms of the overprotection of the patients by their entourage and/or the low health literacy of populations to understand the effect of PA on their health may play a role. There is a need for new approaches that consider the individual barriers and facilitators to exercise.

Effect of mixed and collective physical activity in chronic stroke rehabilitation: A randomized cross-over trial in low-income settings.

BACKGROUND: The prevalence of physical inactivity after stroke is high and exercise training improves many outcomes. However, access to community training protocols is limited, especially in low-income settings. OBJECTIVE: To investigate the feasibility and efficacy of a new intervention: Circuit walking, balance, cycling and strength training (CBCS) on activity of daily living (ADL) limitations, motor performance, and social participation restrictions in people after stroke. METHODS: Forty-six community-dwelling individuals with chronic stroke who were no longer in conventional rehabilitation were randomized into an immediate CBCS group (IG; initially received CBCS training for 12 weeks in phase 1), and a delayed CBCS group (DG) that first participated in sociocultural activities for 12 weeks. In phase 2, participants crossed over so that the DG underwent CBCS and the IG performed sociocultural activities. The primary outcome was ADL limitations measured with the ACTIVLIM-Stroke scale. Secondary outcomes included motor performance (balance: Berg Balance Scale [BBS], global impairment: Stroke Impairment Assessment Set [SIAS] and mobility: 6-minute and 10-metre walk tests [6MWT and 10mWT] and psychosocial health [depression and participation]). Additional outcomes included feasibility (retention, adherence) and safety. RESULTS: ADL capacity significantly improved pre to post CBCS training (ACTIVLIM-stroke, +3,4 logits, p < 0.001; effect size [ES] 0.87), balance (BBS, +21 points, p < 0.001; ES 0.9), impairments (SIAS, +11 points, p < 0.001; ES 0.9), and mobility (+145 m for 6MWT and +0.37 m/s for 10mWT; p < 0.001; ES 0.7 and 0.5 respectively). Similar improvements in psychosocial health occurred in both groups. Adherence and retention rates were 95% and 100%, respectively. CONCLUSION: CBCS was feasible, safe and improved functional independence and motor abilities in individuals in the chronic stage of stroke. Participation in CBCS improved depression and social participation similarly to participation in sociocultural activities. The benefits persisted for at least 3 months after intervention completion.

Relationships between walking speed, activities and participation in people with chronic stroke in Burundi.

Background: Reduced walking speed because of a stroke may limit activities of daily living (ADLs) and restrict social participation. Objectives: To describe the level of balance impairment, activity limitations, and participation restrictions and to investigate their relationship with walking speed in Burundians with chronic stroke. Methods: This cross-sectional study involved adult stroke survivors. Walking speed, balance, ADLs and social participation were assessed with the 10-meter walk test (10 mWT), the Berg balance scale (BBS), the activity limitation stroke scale and the participation measurement scale, respectively. In order to determine ambulatory independence status, participants were stratified into three walking speed groups (household ambulation, limited ambulation and full-community ambulation), based on the Perry classification. Results: Fifty-eight adults (mean age 52.1 ± 11.4 years) with chronic stroke were included in our study. Most participants had severe balance impairments (median BBS score, 27). Their mean (± standard deviation [SD]) walking speeds, ADL levels and social participation levels were 0.68 ± 0.34 m/s, 50.8% ± 9.3% and 52.8% ± 8.6%, respectively. Walking speed correlated moderately with balance (rho = 0.5, p < 0.001) and strongly with ADL level (r = 0.7, p < 0.001) but not with participation level (r = 0.2, p = 0.25). Conclusion: Using socio-culturally suitable tools, our study showed that walking speed correlates robustly with balance and ADL ability, but not with social participation, in Burundi, a low-income country. Clinical implications: Exercises targeting walking speed would be very useful for people with chronic stroke living in low-resource countries, in order to promote their functional independence.

Biopsychosocial factors associated with chronic low back pain-related activity limitations in Burundi.

Background: Chronic low back pain (CLBP) is an increasing burden worldwide. The biopsychosocial factors associated with CLBP-related activity limitations have not yet been investigated in Burundi. Objective: The aim of our study was to investigate the biopsychosocial factors that influence the CLBP-related activity limitations in a Burundian sample population. Method: We carried out a cross-sectional study of 58 adults with nonspecific CLBP from Bujumbura city. Univariate and bivariate analyses were used to investigate the association between biopsychosocial factors and CLBP activity limitations. Sequential multiple regression analyses were subsequently used to predict CLBP activity limitations. Results: Fifty-eight individuals with a mean age of 41.3 ± 10.20, 58.6% of female gender, were recruited. The univariate and bivariate analyses demonstrated that educational level, gender, healthcare coverage, profession, height, pain intensity, depression and physical fitness were significantly associated with CLBP-related activity limitations (p range, < 0.001 to < 0.05). The multivariate regression analysis showed that the significant biopsychosocial factors accounted for 49% of the variance in self-reported activity limitations. Predictors of activity limitations were education level (ß = -0.369; p = 0.001), abdominal muscle endurance (ß = -0.339; p = 0.002) and depression (ß = 0.289; p = 0.011). Conclusions: Our study provides evidence of biopsychosocial factor associations with CLBP-related activity limitations in Burundi. Evidence-based management and prevention of CLBP in Burundi should incorporate a biopsychosocial model. Clinical implications: Biopsychosocial factors should be regularly evaluated in people with chronic low back pain and efforts to improve the burden of chronic low back pain in Burundi should take these factors into account.

Prevalence and biopsychosocial factors associated with chronic low back pain in urban and rural communities in Western Africa: a population-based door-to-door survey in Benin.

PURPOSE: This study aimed to assess the prevalence of chronic low back pain (CLBP) and related biopsychosocial factors in urban and rural communities in Benin. METHODS: This is a population-based observational cross-sectional survey. An interviewer-administered electronic questionnaire was used to collect information on demographic, socio-economic, behavioral, and psychological factors relating to CLBP risk factors and medical history of participants. The numeric pain rating scale and the Beck Depression Inventory were used to assess pain intensity and the level of depression, respectively. Bivariate analyses were performed to investigate the association between sociodemographic, behavioral, and psychological factors and CLBP. Sequential multiple regression analyses were subsequently performed to predict the occurrence of CLBP. RESULTS: A total of 4320 participants, with a mean age ± SD of 32.9 ± 13.1 years, of which 40.7% were females and 50.1% from an urban area, were enrolled in the study. We found a global prevalence rate of CLBP of 35.5% [95% CI 34.1-36.9%]. The prevalence in urban areas was 30.68% [95% CI 28.9-32.8%]) while 40.2% was found in rural areas [95% CI 38.1-42.2%]). Age (p < 0.001), level of education (p = 0.046), marital status (p < 0.001), working status (p < 0.003), tobacco use (p < 0.016) and regular physical activity (p < 0.011) were associated with CLBP. In urban areas, only the level of education was able to predict the prevalence of CLBP (R2 = 61%). In rural areas, CLBP was predicted by age, marital and working status (R2 = 89%). CONCLUSIONS: This study showed a high prevalence of CLBP among urban and rural communities in Benin. Age, level of education, marital status, and working status were significantly associated with CLBP in Benin.
