Translation and adaptation of the Arabic version of the injustice experience questionnaire in patients with chronic musculoskeletal pain.

OBJECTIVE: The objectives of this study were to (1) translate the short version of the Injustice Experience Questionnaire (IEQ-SF) from English to Arabic and (2) test the validity and reliability of the translated Arabic version of the IEQ-SF. SUBJECTS AND METHODS: A cross-sectional study in which the original English version of the IEQ-SF was translated into Arabic was conducted in accordance with Beaton's translation process. Internal consistency, reproducibility (retest within 5 days), and validity of the translated Arabic version of the IEQ-SF were tested in Arabic-speaking participants (n = 20). Individuals with chronic pain (n = 99) completed the Arabic versions of the IEQ-SF and the Musculoskeletal Health Questionnaire (MSK-HQ) from June to August 2021. The main analyses included Cronbach's alpha (α), Intraclass Correlation Coefficients (ICC), and Spearman's rank correlations (ρ). RESULTS: The internal consistency (α = 0.74) and test-retest reliability (ICC = 0.88, 0.83-0.92 95% CI) for the translated Arabic version of IEQ-SF were high. There was also a high correlation between the translated Arabic version of the IEQ-SF and different health-related questionnaires such as the MSK-HQ (ρ = -0.738; p < 0.001), Hospital Anxiety and Depression Scale (ρ = 0.701-0.791; all, p < 0.001), and Pain Catastrophizing Scale (ρ = 0.762; p < 0.001). CONCLUSIONS: The Arabic version of the IEQ-SF demonstrated high reliability and validity and would be useful for clinicians and researchers studying Arabic-speaking individuals with chronic pain.

Association between COVID-19 exposure and autonomic nervous system dysfunction in apparently healthy adults: an observational study.

OBJECTIVE: Coronavirus disease (COVID-19) is a respiratory disease caused by SARS-CoV-2, which complicates the functioning of multiple systems, including the autonomic nervous system (ANS), causing dysautonomia. Investigation of dysautonomia and its association with exposure to COVID-19 is limited in healthy people. Therefore, the study aimed to investigate the relationship between ANS dysautonomia and coronavirus exposure and compare the ANS function between exposed and non-exposed to COVID-19. SUBJECTS AND METHODS: The study involved 141 participants, with a mean age of 18-24.5 years, 83% male (49.6% exposed to COVID-19). The ANS was measured using a composite autonomic symptom scale (COMPASS-31) questionnaire and heart rate variability (HRV) using photoplethysmography. Exposure to COVID-19 was investigated using two national health-status tracking and COVID-19 exposure applications, "Sehhaty" and "Twakkalna". RESULTS: A significantly inverse weak correlation between COMPASS-31 scores and COVID-19 exposure (r=-0.2, p=0.04). No significant association was found between HRV and COVID-19 exposure. COMPASS-31 scores for the exposed group (median=15, n=70) were significantly higher than those for the non-exposed group (median=12, n=71), U=1,913.5, p=0.03. Height (r=-0.4, p=0.002) and gender (r=0.3, p=0.001) were moderately correlated with COMPASS-31 among the exposed group. CONCLUSIONS: These findings indicated that exposure to COVID-19 was associated with poorer ANS scores measured via COMPASS-31. Additionally, exposure to COVID-19 resulted in higher dysautonomia symptoms than non-exposed. Height and gender differences contribute to the severity of dysautonomia among exposed people.

Virtual reality-based exercises' effects on pulmonary functions, cardiopulmonary capacity, functional performance, and quality of life in children with repaired congenital diaphragmatic hernia.

OBJECTIVE: The long-term consequences of congenital diaphragmatic hernia (CDH), which include altered lung functions and compromised cardiopulmonary capacity, impact functional performance and quality of life. This study investigates the effects of virtual reality-based exercise programs on pulmonary functions, cardiopulmonary capacity, functional performance, and quality of life in children with repaired CDH. PATIENTS AND METHODS: A randomized controlled clinical trial was performed. Fifty-two children with repaired CDH (aged 6-10 years) were enrolled and randomly allocated to virtual reality-based exercises plus traditional physical therapy (VR-EX group, n = 26) or traditional physical therapy alone (control group, n = 26). Interventions were conducted three times a week for 12 weeks. Pulmonary functions, cardiopulmonary capacity, functional performance, and quality of life were assessed before and after the intervention. RESULTS: The VR-EX group demonstrated significantly enhanced post-treatment pulmonary functions and cardiopulmonary capacity compared to the control group after accounting for the pre-treatment values (p < 0.05). In addition, the values in functional performance and quality of life measures showed significantly larger improvements in the VR-EX group (p < 0.05). CONCLUSIONS: Children with repaired CDH may benefit more from VR-based exercises when combined with traditional physical therapy than from traditional physical therapy alone regarding their pulmonary functions, cardiopulmonary capacity, functional performance, and quality of life.

Distinct effects of trampoline-based stretch-shortening cycle exercises on muscle strength and postural control in children with Down syndrome: a randomized controlled study.

OBJECTIVE: The aim of the study was to investigate the effect of a 3-month, trampoline-based stretch-shortening cycle (SSC) exercises on muscle strength and postural control in children with Down's syndrome (DS). PATIENTS AND METHODS: Thirty-two children with DS aged between 7-9 years were enrolled and randomly assigned into the control group (n = 16); received standard physical therapy (sPT) or SSC group (n = 16); received sPT in addition to a 15-minute, trampoline-based SSC training program twice per week for 12 successive weeks. Lower limb muscle strength and postural stability [anterior/posterior stability index (A/P-SI), medial/lateral stability index (M/L-SI)], and overall stability index (O-SI) were assessed pre- and post-treatment. RESULTS: Strength of hip extensor (p=0.034) and adductor (p=0.015), knee extensor (p=0.028) and flexor (p=0.01), and ankle dorsi (p=0.033) and plantar flexor (p=0.007) muscles increased significantly in the SSC group when compared with the control group. Also, the A/P-SI (p=0.019), M/L-SI (p=0.002), and O-SI (p=0.021) decreased significantly in the SSC group when compared with the control group, suggesting better postural control. CONCLUSIONS: Twelve weeks of trampoline-based SSC exercises are likely effective for enhancing muscle strength and postural control in children with DS and should consequently be included in the rehabilitation programs for these children.

Incorporation of Pilates-based core strengthening exercises into the rehabilitation protocol for adolescents with patellofemoral pain syndrome: a randomized clinical trial.

OBJECTIVE: The objective of this study was to evaluate how a Pilates-based core strengthening exercise program affected pain, lower limb muscle strength, functional status, and health-related quality of life in adolescents with patellofemoral pain syndrome (PFPS). MATERIALS AND METHODS: In this randomized controlled clinical trial, 34 teenagers with PFPS (ages 14-17) were randomly assigned to receive either a standard PT program (control group) or Pilates exercises plus the conventional program (study group). Both groups continued the treatment sessions for 3 months (3 sessions/week). Pain intensity, lower limb muscle strength (hip abductors and external rotators and knee extensors), functional status, and health-related quality of life were evaluated pre-and post-intervention. RESULTS: Pain intensity (p =.005) reduced significantly post-treatment in the study group as compared to the control group, when controlled for the pre-treatment value. Also, muscle strength of hip abductors (p =.002) external rotators (p < .001), knee extensors (p = .013), functional status (p = .002), and health-related quality of life (p < .001) increased significantly in the study group when compared to the control group. CONCLUSIONS: The results of this study show that Pilates-based core strengthening exercises can help adolescents with PFPS reduce pain, enhance muscle strength, and improve their functional status and quality of life.

Prospective analysis of physical activity levels and associated fitness factors amid COVID-19 pandemic and social-distancing rules. A special focus on adolescents.

Objective: Physical activity is a significant health determinant and is likely to be influenced by social-distancing rules imposed by authorities during the COVID-19 pandemic. This study explored gender-based differences in physical activity levels (PALs) and associated factors amid COVID-19 pandemic in adolescents. Methods: In this prospective analysis, 112 healthy adolescents (15.63 ± 1.21 years) participated. They were assessed at the baseline (before the announcement of COVID-19 as a global pandemic) for anthropometry, fitness status, and PALs (baseline-PALs), and next at the follow-up (three months of imposed social-distancing rules) for PALs (follow-up-PALs) over an internet-based platform through the Physical Activity Questionnaire for Adolescents. Results: A significant PALs decline was evidenced for the whole sample (P < .001) and such a decline was predominantly affected by significant PALs reduction among males (P < .001) rather than in females (P = .06). The fitness variables (explosive power, muscle endurance, flexibility, and aerobic endurance) were consistently positively correlated with the baseline- and follow-up-PALs in both genders with particularly prominent associations of PALs with explosive power and aerobic endurance. Conclusion: Physical literacy is necessary for PALs preservation, given the remarkable PALs decreases among adolescents during challenging circumstances such as the COVID-19 pandemic.

Objectif: L'activité physique est un déterminant important de la santé et est susceptible d'être influencée par les règles de distanciation sociale imposées par les autorités pendant la pandémie de COVID-19. Cette étude a exploré les différences basées sur le sexe dans les niveaux d'activité physique (PAL) et les facteurs associés au milieu de la pandémie de COVID-19 chez les adolescents. Méthodes: Dans cette analyse prospective, 112 adolescents en bonne santé (15,63 ± 1,21 ans) ont participé. Ils ont été évalués au départ (avant l'annonce du COVID-19 en tant que pandémie mondiale) pour l'anthropométrie, le statut de forme physique et les PAL (PAL de référence), et ensuite lors du suivi (trois mois de règles de distanciation sociale imposées) pour les PAL (suivi-PAL) sur une plate-forme internet via le questionnaire sur l'activité physique pour adolescents. Résultats: Une baisse significative des PAL a été mise en évidence pour l'ensemble de l'échantillon (p < ,001) et une telle baisse a été principalement affectée par une réduction significative des PAL chez les hommes (p < ,001) plutôt que chez les femmes (p = ,06). Les variables de forme physique (puissance explosive, endurance musculaire, flexibilité et endurance aérobie) étaient constamment corrélées positivement avec les PAL de référence et de suivi chez les deux sexes avec des associations particulièrement importantes de PAL avec la puissance explosive et l'endurance aérobie. Conclusion: La littératie physique est nécessaire pour la préservation des PAL, étant donné les diminutions remarquables des PAL chez les adolescents lors de circonstances difficiles telles que la pandémie de COVID-19.
