Obesity and overweight as risk factors for low back pain in children and adolescents: a meta-analysis.

BACKGROUND: Childhood obesity and overweight are associated with musculoskeletal pain, but the association between low back pain (LBP) and overweight/obesity in this population needs clarification. The objective of this meta-analysis is to ascertain the relationship between LBP and obesity/overweight in children and adolescents. METHODS: Various databases and specialized journals were queried from inception to October 2022. Encompassed were all studies examining the association between overweight or obesity and LBP among participants aged 6 to 18 years. The ROBINS-E tool was employed to assess bias. Random-effects models were used to pool results across studies, with location-scale models used to search for moderator variables where evidence of heterogeneity was found. RESULTS: In total, 34 studies were incorporated. Four studies had a low risk of bias, while the remaining studies had some concerns. Nine studies evinced an association between overweight and LBP, in contrast to normal weight, yielding an OR of 1.13 (95% CI 1.10-1.16) and no heterogeneity. Eight studies demonstrated a similar association between obesity and LBP compared to normal weight, with an OR of 1.27 (95% CI 1.20-1.34) and no heterogeneity. Ten studies established an association between overweight/obesity and LBP compared to normal weight, yielding an OR of 1.18 (95% CI 1.14-1.23) and no heterogeneity. Finally, nineteen studies showcased an association between body mass index (BMI) and LBP, with an OR of 1.19 (95% CI 1.03-1.39) with evidence of heterogeneity. For this last analysis, we compared the mean BMI in groups and transformed results to log OR, and then retransformed to OR. CONCLUSION: Overweight and obesity may be risk factors for LBP in children and adolescents. The association between LBP and obesity appears to be stronger than with overweight. However, the analysis revealed considerable heterogeneity and risk of bias across studies.

Treatment with robot-assisted gait trainer Walkbot along with physiotherapy vs. isolated physiotherapy in children and adolescents with cerebral palsy. Experimental study.

BACKGROUND: Improving walking ability is a key objective in the treatment of children and adolescents with cerebral palsy, since it directly affects their activity and participation. In recent years, robotic technology has been implemented in gait treatment, which allows training of longer duration and repetition of the movement. To know the effectiveness of a treatment with the robotic-assisted gait trainer Walkbot combined with physiotherapy compared to the isolated physiotherapy treatment in children and adolescents with cerebral palsy, we carried out a clinical trial. METHODS: 23 participants, were divided into two groups: experimental and control. During 5 weeks, both groups received their physiotherapy sessions scheduled, in addition experimental group received 4 sessions per week of 40 min of robot. An evaluation of the participants was carried out before the intervention, at the end of the intervention, and at follow-up (two months after the end of the intervention). Gait was assessed with the Gross Motor Function Measure-88 dimensions D and E, strength was measured with a hydraulic dynamometer, and range of motion was assessed using the goniometer. A mixed ANOVA was performed when the assumptions of normality and homoscedasticity were met, and a robust mixed ANOVA was performed when these assumptions were not met. Statistical significance was stipulated at p < 0.05. For the effect size, η2 was calculated. RESULTS: Significant differences were found regarding the time x group interaction in the Gross Motor Function Measure-88 in dimension D [η2 = 0.016], in the flexion strength of the left [η2 = 0.128] and right [η2 = 0.142] hips, in the extension strength of the right hip [η2 = 0.035], in the abduction strength of the left hip [η2 = 0.179] and right [η2 = 0.196], in the flexion strength of the left knee [η2 = 0.222] and right [η2 = 0.147], and in the range of motion of left [η2 = 0.071] and right [η2 = 0.053] knee flexion. CONCLUSIONS: Compared to treatments without walking robot, physiotherapy treatment including Walkbot improves standing, muscle strength, and knee range of motion in children and adolescents with cerebral palsy.

Cross-cultural validation and psychometric properties of the Spanish version of the quality of life in Childhood epilepsy Questionnaire (QOLCE-55).

OBJECTIVE: The aims of the present study were to translate and validate the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) into Spanish. METHODS: A backtranslation procedure was used to translate the English version of QOLCE-55 to Spanish, and subsequently, parents of 88 children (aged four to 12 years), completed the Spanish version of three self-reported questionnaires: the QOLCE-55, the Pediatric Quality-of-Life Inventory (PedsQLTM 4.0), and the Pediatric Sleep Questionnaire (PSQ). Seven to 10 days later, parents completed the questionnaires again under the same conditions. RESULTS: Internal consistency was between 0.669 and 0.968 for the four subscales: cognitive (CF), emotional (EF), social (SF) and physical functioning (PF); and 0.954 for the total score. The test-retest reliability assessed with the intraclass correlation coefficient obtained values from 0.683 for SF to 0.962 for CF. The standard error of measurement for the total score was 5.776, and the minimal detectable change was 16.01. Spearman correlations between the total score of the Spanish version of the QOLCE-55 with the subscales was 0.760 for the CF, 0.776 for the EF, 0.799 for the SF, and 0.682 for the PF (p < 0.001). Convergent validity of QOLCE-55 with the PedsQLTM 4.0 scale was -0.962 (p < 0.001), and the discriminant validity of the QOLCE-55 with PSQ was 0.154 (p = 0.272). This version presented a correlation with maximum lifetime consumption of anti-epileptic drugs (0.500; p < 0.001), and current consumption (0.448; p < 0.001). CONCLUSIONS: The Spanish version of the QOLCE-55 has demonstrated adequate psychometric properties, indicating that it can be confidently used to measure the health-related quality-of-life (HRQoL) in children with epilepsy in a Spanish-speaking population. These results corroborate the instrument's cross-cultural validity.

Effect of a physical exercise program supported by wearable technology in children with drug-resistant epilepsy. A randomized controlled trial.

PURPOSE: to investigate the effects of a physical exercise (PE) program, supported by wearable technology (WT), in children with drug-resistant epilepsy (DRE). METHODS: 29 children with DRE were randomized to experimental (EG) and control (CG) groups. To encourage PE, the EG performed one hour of aerobic activity three days a week for six months, outside the school setting. Compliance was monitored using activity wristbands, with data reported weekly by parents. Health-related quality of life (HRQoL), seizure frequency, physical activity (PA), physical fitness (musculoskeletal, motor, and Cardiorespiratory Fitness), and body composition, were assessed at baseline, at three and six months. RESULTS: Seizure frequency in the last six months evolved from 10.5 seizures/week at baseline, to 4.5 at the end of the study in the EG, and from 5.2 seizures/week to one in the CG. Significant differences were found in weekly hours-PE (η2= 0.49); motor fitness (η2= 0.08); Cardiorespiratory Fitness (η2= 0.19); weight (η2= 0.003); Triceps skinfold thickness (η2= 0.05); lower limb muscular strength (η2= 0.03); HRQoL (η2= 0.02); and PA (η2= 0.22). Post-hoc ANOVA revealed that EG improved significantly (p < 0.05) between baseline and six months. Negative correlations were observed between PA and seizure frequency. CONCLUSION: Supported by WT, children with DRE increased the weekly hours of PE at three and six months, with no increase in seizure frequency. Our study provides evidence of the effectiveness of PE for improving HRQoL.

Assessment of the Effects of Physiotherapy on Back Care and Prevention of Non-Specific Low Back Pain in Children and Adolescents: A Systematic Review and Meta-Analysis.

Non-specific low back pain (NSLBP) in children and adolescents has increased in recent years, and the evidence of the physiotherapy interventions in back care needs to be updated. Our main goal was to quantify the effects of preventive physiotherapy interventions on improving behavior and knowledge related to back care and prevention of NSLBP in children and adolescents. Based on two previous meta-analyses, Cochrane Library, MEDLINE, PEDro, Web of Science, LILACS, IBECS, PsycINFO, and IME databases and several journals were searched. Two researchers independently extracted data and assessed the risk of bias in the studies using the RoB2 tool. Data were described according to PRISMA guidelines. A total of 24 studies (28 reports) were included. In the posttest, the behavior variable obtained an overall effect size of d+ = 1.48 (95%CI: 0.40 to 2.56), and the knowledge variable obtained an effect size of d+ = 1.41 (95%CI: 1.05 to 1.76). Physiotherapy has demonstrated beneficial impacts on behavior and knowledge concerning back care and to prevent NSLBP in children and adolescents. Interventions focusing on postural hygiene and exercise should be preferred, especially those that are shorter in number of weeks, more intense, and incorporate as many intervention hours as possible.

High Medial Longitudinal Arch of the Foot and Latent Trigger Points in Lower Limb Muscles.

Background: The objective was to evaluate the prevalence of latent trigger points (LTrPs) in lower limb muscles in participants with a high medial longitudinal arch (MLA) of the foot compared to controls. Methods: Participants with a navicular drop test of 4-9 mm were included in the control group; the high MLA group included navicular drop test values of ≤4 mm. The presence of LTrPs was assessed by palpation techniques. The muscles evaluated were medial gastrocnemius (LTrP1), lateral gastrocnemius (LTrP2), soleus (LTrP1), peroneus longus, peroneus brevis, tibialis anterior, extensor digitorum longus, flexor digitorum longus, rectus femoris, vastus medialis (LTrP1 and LTrP2), and the vastus lateralis of the quadriceps (LTrP1 and LTrP2). Results: Thirty-seven participants with high MLA and thirty-seven controls were included in the study. Twenty-nine (78.4%) participants in the high MLA group had at least 1 LTrP, compared to twenty-three (62.2%) in the control group. No statistical difference (p < 0.05) was found in the total number of LTrPs between groups (4.46 ± 3.78 vs. 3.24 ± 3.85). There were more participants (p < 0.05) with LTrPs in the tibialis anterior, extensor digitorum longus, and vastus lateralis (LTrP1 and LTrP2) in the high MLA group than in the control group. Conclusion: Although no differences were found in the number of total LTrPs between groups, the prevalence was statistically significantly higher in the tibialis anterior, extensor digitorum longus, and vastus lateralis of the participants with high MLA of the foot.

Actividad física, tabaquismo y consumo de alcohol, en un grupo de estudiantes universitarios / Physical activity and tobacco and alcohol use in a group of university students

Objetivo Determinar la prevalencia de actividad física, tabaquismo y consumo de alcohol, en un grupo de estudiantes universitarios. Metodología Con una muestra de 548 estudiantes del área socio-sanitaria (431 mujeres y 117 hombres, edad media: 20 años DT: 2,3) se aplicó la versión abreviada del Cuestionario Internacional de Actividad Física y una encuesta sobre hábitos de vida, para obtener información relacionada con el consumo de alcohol y tabaquismo. Se calcularon el índice de actividad física, los niveles de actividad, porcentaje de tabaquismo y consumo de alcohol. Se aplicó la prueba V de Cramer para establecer asociación entre variables, la prueba t para evaluar las diferencias de actividad física en función del género y la prueba Brown Forsythe en función de la titulación. Resultados El 80 % de los estudiantes se clasificaron como regularmente activos. Se encontraron diferencias significativas entre Índice de Actividad Física, género (p=0,0) y titulación (p=0,038). La prevalencia de tabaquismo fue del 33 % y de consumo de alcohol fue del 58 %; sin diferencias significativas entre género. No se encontraron asociaciones significativas entre actividad física, tabaquismo y consumo de alcohol. Conclusiones Un porcentaje alto de estudiantes practican actividad física de forma regular. Sin embargo, una parte de ellos no alcanza el parámetro mínimo para obtener beneficios en la salud. El porcentaje de consumo de alcohol y tabaquismo fue elevado. Se requiere implementar programas de promoción de hábitos saludables en universitarios, específicamente hacia la optimización de la práctica deportiva, la prevención y disminución del tabaquismo y consumo de alcohol.

Objective Determining the prevalence of physical activity, smoking and drinking alcohol in a group of university students studying in the social-health sciences' area. Methodology A shortened version of the International Physical Activity Questionnaire was used with a sample of 548 students from the social-health sciences area (431 females and 117 males, average 20 years old: 2.3 SD) and a survey about living habits for obtaining information related to drinking alcohol and smoking. The physical activity index, activity levels, percentage of smoking and drinking alcohol were all calculated. The Cramer's V coefficient was used for establishing an association between variables, the t-test for evaluating differences in physical activity regarding gender and the Brown Forsythe test concerning qualifications. Results 80 % of the students were classified as being regularly active. Significant differences were found between the Physical Activity Index, gender (p=0.0) and qualifications (p=0.038). Smoking prevalence was 33 % and drinking alcohol 58 %, no significant differences being found regarding gender. No significant associations were found between physical activity, smoking and drinking alcohol. Conclusions A high percentage of students regularly took part in physical activity. However, some of them did not reach the minimum parameters for obtaining health-related benefits. The percentage of students consuming alcohol and smoking was high. Programs must be implemented for promoting healthy habits in university students, specifically aimed at optimizing taking part in sports and preventing and reducing smoking and drinking alcohol.
