Purpose:
The purpose of this study is to compare scapular alignment, muscle strength around the scapula and neck according to the classification of forward head posture (FHP), round shoulder posture (RSP) and forward head with round shoulder posture (FHRSP).
Methods:
Scapular alignment, muscle strength around the scapula, and neck strength were measured according to the FHP and RSP alignment classification for male college students. Scapular alignment was confirmed by measuring acromial depression, scapular lateral displacement, and scapular acromion distance. Muscle strength was measured during isometric contraction of upper trapezius (UT), middle trapezius (MT), lower trapezius (LT), and neck muscles.
Results:
Acromial depression was significantly greater in the FHP (7.20±1.02 cm) than in the RSP group (5.60±1.26 cm) and FHRSP (5.26±1.75 cm) (p<0.05). The strength of the UT was significantly greater in the FHRSP (1.12±0.12 N/BW) than in the FHP (0.87±0.19 N/BW), and the strength of the LT was significantly greater in the control group (0.20±0.04 N/BW) than in the FHP (0.15±0.03 N/BW) and RSP (0.15±0.04 N/BW) (p<0.05). The LT:UT ratio was significantly greater in the control group (0.20±0.05) than in the FHRSP (0.15±0.02) (p<0.05).
Conclusion
UT strength was higher in RSP subjects with scapular elevation accompanied by FHP than in those with FHP alone. And LT strength and the LT:UT ratio were higher in subjects withno abnormalities in postural alignment. We suggest that these results can serve as a reference for evaluation and intervention according to postural alignment in clinical practice.

Journal of Clinical Neurology 2024;20(1):86-93
Background:
and Purpose Patients with cluster headache (CH) exhibit impaired health-related quality of life (HRQoL). However, there have been few studies related to the HRQoL of patients with CH from Asian backgrounds. This study aimed to determine the impact of CH on HRQoL and to identify the factors affecting HRQoL in patients with CH during cluster periods.
Methods:
This prospective study enrolled patients with CH from 17 headache clinics in South Korea between September 2016 and February 2021. The study aimed to determine HRQoL in patients with CH using the EuroQol 5 Dimensions (EQ-5D) index and the time trade-off (TTO) method. Age- and sex-matched headache-free participants were recruited as a control group.
Results:
The study included 423 patients with CH who experienced a cluster period at the time. EQ-5D scores were lower in patients with CH (0.88±0.43, mean±standard deviation) than in the controls (0.99±0.33, p<0.001). The TTO method indicated that 58 (13.6%) patients with CH exhibited moderate-to-severe HRQoL deterioration. The HRQoL states in patients with CH were associated with current smoking patterns, headache severity, frequency, and duration, and scores on the Generalized Anxiety Disorder 7-item scale (GAD-7), Patient Health Questionnaire 9-item scale (PHQ-9), 6-item Headache Impact Test, and 12-item Allodynia Symptom Checklist. Multivariable logistic regression analyses demonstrated that the HRQoL states in patients with CH were negatively correlated with the daily frequency of headaches, cluster period duration, and GAD-7 and PHQ-9 scores.
Conclusions
Patients with CH experienced a worse quality of life during cluster periods compared with the headache-free controls, but the degree of HRQoL deterioration varied among them. The daily frequency of headaches, cluster period duration, anxiety, and depression were factors associated with HRQoL deterioration severity in patients with CH.

Objective:
This study aimed to evaluate the prevalence of urinary incontinence (UI) and its associated risk factors among pregnant Korean women, as UI significantly impacts their quality of life.
Methods:
A cross-sectional study involving singleton pregnant women was conducted between April and December 2023. Data were collected using a questionnaire assessing demographic information and UI symptoms. The International Consultation on Incontinence Questionnaire-UI short form was used to diagnose UI.
Results:
A total of 824 pregnant women from three centers participated, with an overall prenatal UI prevalence of 40.2% (331/824). Stress UI was most common (77.1%), followed by mixed UI (16.9%), and urgency UI (6.0%). Risk factors for UI included prior delivery mode, specifically vaginal delivery (adjusted odds ratio [aOR], 5.61; 95% confidence interval [CI], 1.40-22.50; P=0.015) and combined vaginal and cesarean delivery (aOR, 23.14; 95% CI, 1.77-302.74; P=0.017). Additionally, second trimester (aOR, 1.99; 95% CI, 1.19-3.32; P=0.009) and third trimester (aOR, 4.44; 95% CI, 2.65-7.40; P<0.001) were associated with increased UI risk. Conversely, drinking alcohol before pregnancy was a protective factor (aOR, 0.72; 95% CI, 0.53-0.99; P=0.046).
Conclusion
Approximately 40% of Korean pregnant women experience prenatal UI. Prior delivery mode and advanced gastrointestinal age are significant risk factors. Further research with postpartum and long-term follow-ups is needed.
