Objective: To examine the relationship between learning behaviors and symptoms of office syndrome among 12th-grade students at Patumwan Demonstration School.

Methods: A cross-sectional descriptive study was conducted among 135 12th-grade students at Patumwan Demonstration School during August 2024. Data were collected through a structured questionnaire measuring study duration, break duration, and office syndrome symptoms. Associations between categorical variables were analyzed using the Chi-square test.

Results: A survey of 135 students, comprising 49.6% female, 47.4% male, and 3% who preferred not to specify their gender, aged between 16-19 years, revealed that students who studied continuously for more than 120 minutes reported a significantly higher prevalence of office syndrome symptoms compared to those who studied for less than 60 minutes (x² = 10.45, df = 2, p = 0.005). The most common symptoms were neck, shoulder, and upper back pain. Female students reported symptoms more frequently than male students.

Conclusion: Prolonged study duration was significantly associated with higher office syndrome symptom prevalence. Encouraging regular breaks and ergonomic posture during study sessions may help reduce musculoskeletal strain among students.

Maternal Factors Associated with Term Low Birthweight Infants in Inburi Hospital

Kullapas Juntanon — Tue, 30 Jun 2026 00:00:00 +0700

Low birth weight among newborns remains a major global public health problem, with a continuously increasing incidence. It is associated with increased mortality and both shortand long-term complications in infants. This study aims to identify maternal risk factors associated with term low birth weight infants at Inburi Hospital. A retrospective case–control study was conducted using data from term pregnant women who delivered at the hospital between January 1, 2022 and December 31, 2024. A total of 320 women were included and divided into two groups: the study group comprised 80 mothers who delivered low birthweight infants (< 2,500 g), while the control group comprised 240 mothers who delivered infants weighing ≥ 2,500 g.

The results showed that the incidence of term low birth weight infants was 7.63%. Most mothers were aged 20–34 years, had completed secondary school or vocational education, and were employed as laborers. Maternal factors including health behaviors, underlying diseases, antenatal care, and pregnancy complications were analyzed using multiple logistic regression. Four factors were found to be significantly associated with term low birth weight infants: gestational hypertension or preeclampsia (aOR = 11.32, 95% CI:3.00–42.70), fewer than five antenatal care visits according to quality criteria (aOR = 2.50, 95% CI: 1.38–4.52), primigravidity (aOR = 2.07, 95% CI: 1.18–3.64), and pre-pregnancy body mass index ≥ 30 kg/m² (aOR = 0.35, 95% CI: 0.13–0.95). Therefore, these factors should be considered together with preconception maternal health preparation, risk assessment during pregnancy, and adequate antenatal care according to quality standards.

Hip fractures in elderly are a common condition associated with complications, mortality, loss of mobility, and a substantial burden on healthcare systems. This study aims to compare clinical outcomes between patients who underwent surgery within 72 hours and those who underwent surgery after 72 hours following admission to Samutprakan Hospital.

This retrospective cohort study included patients aged 60 years and older who were diagnosed with intertrochanteric hip fractures and underwent internal fixation with Proximal Femoral Nail Antirotation (PFNA) at Samutprakan Hospital between January 1, 2019 and December 31, 2024. A total of 451 patients were enrolled and categorized into two groups according to time to surgery: surgery within 72 hours and surgery after 72 hours. The primary outcome was 1-year mortality from the date of hospital admission. Secondary outcomes included postoperative complications and length of hospital stay. Data were analyzed using descriptive statistics, Independent t-test, Mann–Whitney U test, Chi-square test, or Fisher’s exact test as appropriate. Risk Ratio (RR), 95% confidence intervals (CI), and p-values were reported.

The results showed that among 451 patients, most underwent surgery within 72 hours (60.3%). The overall 1-year mortality rate was 8.6%. There was no statistically significant difference in 1-year mortality between the two groups (p = 0.169). Patients who underwent surgery after 72 hours had a 1.60-fold higher risk of 1-year mortality compared with those who underwent surgery within 72 hours; however, the difference was not statistically significant (RR = 1.60; 95% CI: 0.88–2.91). Nevertheless, delayed surgery beyond 72 hours was significantly associated with higher rates of urinary tract infection (p < 0.001), higher rates of pressure ulcers (p = 0.017), and a longer median length of hospital stay (p < 0.001).

Effects of OTAGO Exercise and Conventional Balance Training on Balance in Stroke Patients

Siwaporn Srilou — Tue, 30 Jun 2026 00:00:00 +0700

Stroke patients commonly experience hemiparesis, resulting in impaired motor control of the affected side and balance deficits, which increase the risk of falls and limit functional mobility. Exercise interventions are widely used to improve balance and reduce fall risk. The Otago Exercise Program has been shown to enhance lower limb muscle strength, stimulate neuromuscular function, increase weight-bearing on the affected limb, and improve proprioception, thereby promoting balance performance.

This quasi-experimental study aims to compare the effects of the Otago Exercise Program and conventional balance training on balance performance in stroke patients at Samutprakan Hospital. Thirty participants were allocated into two groups using systematic alternating assignment. Fifteen participants in the experimental group received the Otago Exercise Program, while fifteen participants in the control group underwent conventional balance training. Both interventions were conducted for 8 weeks. Balance performance was assessed using the Berg Balance Scale (BBS) and the Functional Reach Test (FRT). Within-group comparisons before and after the intervention were analyzed using paired-sample t-tests, while between-group comparisons were performed using independent t-tests.

The results demonstrated significant improvements in both BBS and FRT scores in both groups following the intervention (p < 0.05). Comparison of post-intervention outcomes between the groups revealed no significant difference in BBS scores. However, the experimental group showed significantly greater improvement in FRT scores than the control group (p < 0.05). The findings suggest that the Otago Exercise Program is effective in improving balance and functional mobility in stroke patients.

A Comparative Study Outcome of William's Flexion Exercise and Core Stability Training Programs Combined with Back Traction on Lumbar Spinal Stenosis Patients Rehabilitate

Peanyanunt Rueanrudipirom — Tue, 30 Jun 2026 00:00:00 +0700

Background: Lumbar spinal stenosis (LSS) is a major cause of low back pain and functional limitations in older adults. Lumbar traction combined with exercise therapy is widely used in physical therapy practice; however, comparative evidence regarding different exercise approaches remains limited. This study aims to compare the effects of William's Flexion Exercise (WFE) combined with lumbar traction, Core Stability Training (CST) combined with lumbar traction, and lumbar traction alone on pain intensity, functional disability, and lumbar range of motion in patients with LSS.

Methods: A randomized controlled trial was conducted among 39 patients diagnosed with LSS. Participants were randomly allocated into three groups (n = 13 per group). The intervention groups received either WFE or CST under the supervision of a physical therapist in addition to lumbar traction and a home exercise program. The control group received lumbar traction alone. Outcomes were assessed after four weeks of intervention.

Results: After four weeks, all groups demonstrated significant within-group improvements in pain intensity and disability scores. The CST group showed the lowest mean Thai Roland Morris Disability Questionnaire (Thai RMDQ) score (5.92 ± 0.84), compared with the WFE group (7.43 ± 0.84) and the control group (8.88 ± 0.84), although the difference did not reach statistical significance (p = 0.056). Multivariable logistic regression analysis demonstrated that participants in the CST group (adjusted odds ratio [aOR] = 9.27, 95% confidence interval [CI]: 1.20–71.55, p = 0.033) and the WFE group (aOR = 7.97, 95% CI: 1.09–58.23, p = 0.041) had significantly higher odds of achieving an overall treatment response than those in the control group.
