Article Synopsis
  • - The study investigates the impact of a 12-week stretch-shortening cycle exercise program on muscle strength, bone mineral density, and upper extremity function in children aged 10-16 with obstetric brachial plexus injury (OBPI).
  • - Fifty-six children with confirmed upper-arm OBPI were randomly assigned to either the exercise group or a control group, focusing on improving muscle and bone metrics over 24 sessions.
  • - Results showed the exercise group had significant improvements in muscle strength and bone mineralization, indicating that the SSC exercise program may be an effective intervention for enhancing physical abilities in these children.

Article Synopsis
  • The study investigates the effects of manual diaphragmatic release combined with respiratory training on cleaning laborers exposed to occupational hazards, comparing it to just respiratory training alone.
  • In a randomized controlled trial, 36 participants aged 35-45 were divided into two groups for a 12-week program, measuring various pulmonary functions and physical performance before and after the intervention.
  • Results showed significant improvements in respiratory function, chest mobility, and walking performance in the group that received diaphragmatic release therapy, suggesting it could help alleviate respiratory distress and enhance immune function in affected workers.

Objectives: To understand the prevalence and survival rates of preterm birth (PTB) is of utmost importance in informing healthcare planning, improving neonatal care, enhancing maternal and infant health, monitoring long-term outcomes, and guiding policy and advocacy efforts.

Methods: The medical records of preterm infants admitted to the Neonatal Intensive Care Unit (NICU) with a diagnosis of prematurity at the Maternity and Children's Hospital (MCH), Al Kharj, Saudi Arabia, were reviewed between January 2018 and December 2022. Data were collected on birth weight (BW), gender, number of live births, gestational age, mortality, nationality, APGAR score, length of stay in the NICU, and maternal details.

Purpose: Respiratory muscle function is compromised in children recovering from chest wall burns, which potentially leads to more impact on exercise capacity and quality of life. This study investigates the effects of an inspiratory muscle training intervention accompanied with a pulmonary rehabilitation program on respiratory muscle strength, lung function, functional capacity, and quality of life in chest burned children.

Methods: Forty children with burns, aged from 10 to 18 years old and total body surface area of 30% to 50%, were randomly allocated to the inspiratory muscle training group (IMT- G: n = 20) or control group (CG: n = 20).

Purpose: This study sought to find out if a 6-week accommodating variable-resistance (AcVR) training might enhance muscle architecture, peak torque, and functional performance in patients with juvenile idiopathic arthritis (Juv-IA).

Methods: Fifty-eight patients with polyarticular Juv-IA (aged 12-18 years) were involved in a randomized controlled trial. They were allocated into two groups: the AcVR group ( = 29; underwent AcVR training, and the control group ( = 29; received the usual exercise regimen).

Aim: To explore how plyometric-based hydro-kinesiotherapy (Plyo-HKT) would affect pain, muscle strength, postural stability, and functional performance in a convenience sample of children with hemophilic knee arthropathy (HKA).

Methods: Forty-eight children with HKA (age: 8-16 years) were randomly allocated to the Plyo-HKT group ( = 24; underwent the Plyo-HKT for 45 min, twice/week over 12 wk in succession) or the comparison group ( = 24; performed the standard exercise rehabilitation at an equivalent frequency and duration). Pain, peak concentric torque of quadriceps and hamstring (produced at two angular velocities: 120 and 180 /sec), dynamic limits of postural stability (DLPS), and functional performance [Functional Independence Score in Hemophilia (FISH) and 6-Minute Walk Test (6-MWT)] were assessed pre- and post-intervention.

The paradigm of comprehensive treatment approaches for children with cerebral palsy has gained traction, prompting clinicians to deliberate between independent and integrated treatment delivery. However, this decision-making process is often hindered by the dearth of empirical evidence available to inform optimal therapeutic strategies. This study, therefore, sought to compare the effects of Pilates-based core strengthening (PsCS), plyometric-based muscle loading (PlyoML), and their combination on postural control, balance, and mobility in children with unilateral cerebral palsy (ULCP).

Purpose: To determine whether a 12-week supervised dose-graded aerobic exercise (D-GAE) training, when implemented in conjunction with traditional rehabilitation, could help pediatric survivors of acute lymphoblastic leukemia (ALL) enhance their cardiopulmonary capacity and improve their physical performance.

Methods: Fifty-eight pediatric survivors of ALL (age 13.78 ± 2.

  • This study looked at how common falls are among adults in Riyadh, Saudi Arabia, and aimed to find risk factors and establish thresholds for fall risk assessments.
  • A total of 276 Arabic-speaking Saudi citizens aged 40 and above shared their fall histories and health information, revealing that 10.14% were classified as fallers.
  • Findings showed that those who fell were more likely to have conditions like arthritis and back pain, and higher depressive symptoms; specific cut-off scores for predicting falls were also identified for these factors.

Background: Individuals with rheumatoid arthritis (RA) are at a high risk of cardiovascular diseases (CVD). A reduced chronotropic response (CR), which produces exercise intolerance, is known to be a contributing factor to CVD and mortality. Studies have shown that patients with RA have a reduced CR.

Aim: To investigate the effects of a 12-week split-belt treadmill walking (Sb-TW) practice using an error augmentation strategy on temporospatial gait asymmetries, dynamic balance, and locomotor capacity in adolescents with unilateral cerebral palsy (ULCP).

Methods: Fifty-two adolescents with ULCP (age: 10-16 years) were randomized into either the Sb-TW group ( = 26; underwent repeated Sb-TW practice, with exaggeration of the initial step-length asymmetry, three times/week, for 12 sequential weeks) or control group ( = 26; received equivalent dosages of traditional single-belt treadmill training). Step-length and swing-time asymmetries, directional (LoS) and overall (LoS) limits of stability, and locomotor capacity [6-minute walk test (6-MWT), Timed Up and Down Stair test (TUDS), and 10-m Shuttle Run Test (10mSRT)] were assessed pre- and post-intervention.

To investigate how plyometric exercise (PLYO-Ex) affects mechanics and morphometrics of the plantar flexor musculotendinous unit in children with unilateral cerebral palsy, 38 participants (aged 10-16 years) were allocated at random to either the PLYO-Ex group ( = 19; received 24 sessions of plyometric muscle loading, conducted 2 times a week for 3 months in succession) or the control group ( = 19; underwent traditional physical therapy for the same frequency and duration). Measurements were taken pre- and post-intervention. Standard ultrasound imaging was applied to evaluate morphometrics of the gastrocnemius muscle and Achilles tendon unit and an isokinetic dynamometer was used to evaluate maximum voluntary isometric plantar flexors contraction (IVC).

Adolescents with unilateral cerebral palsy (U-CP) experience an asymmetrical posture because the less-affected lower limb is preferred for bodyweight support as a strategy of compensating for the paretic side’s muscular weakness. This study was designed to compare the effect of 12 weeks of paretic-limb-only plyometric training (PLPT) and volume-matched double-limb training (DLPT) on balance capability and gait symmetry in adolescents with U-CP. Sixty-nine adolescents with U-CP were randomly assigned to PLPT, DLPT, or a control group (n = 23 each).

Objective: Even though positive implications of inspiratory muscle training (In-MT) have been established in children and adolescents with bronchial asthma (C/AwBA), the role of combined inspiratory and expiratory muscle training (Ex-MT) within the same respiratory cycle (In/Ex-SC) is still unknown. This study was, therefore, set out to explore the effect of In/Ex-SC on respiratory muscle strength, pulmonary functions, and control of asthma symptoms in C/AwBA.

Methods: This was a placebo-controlled randomized clinical investigation that included 51 C/AwBA (12-18 years).
