The survival rate of children admitted in the neonatal intensive care unit (NICU) after birth is on the increase; hence, proper evaluation and care of their neurodevelopment has become an important issue. Neurodevelopmental assessments of individual domains regarding motor, language, cognition, and sensory perception are crucial in planning prompt interventions for neonates requiring immediate support and rehabilitation treatment. These assessments are essential for identifying areas of weakness and designing targeted interventions to improve future functional outcomes and the quality of lives for both the infants and their families. However, initial stratification of risk to select those who are in danger of neurodevelopmental disorders is also important in terms of cost-effectiveness. Efficient and robust functional evaluations to recognize early signs of developmental disorders will help NICU graduates receive interventions and enhance functional capabilities if needed. Several age-dependent, domain-specific neurodevelopmental assessment tools are available; therefore, this review summarizes the characteristics of these tools and aims to develop multidimensional, standardized, and regular follow-up plans for NICU graduates in Korea.

Objectives: The purpose of this study was to cluster long-term multifaceted functional recovery patterns and to establish prediction models for functional outcome in first-time stroke patients using unsupervised machine learning. Methods: This study is an interim analysis of the dataset from the Korean Stroke Cohort for Functioning and Rehabilitation (KOSCO), a long-term, prospective, multicenter cohort study of first-time stroke patients. The KOSCO screened 10,636 first-time stroke patients admitted to nine representative hospitals in Korea during a three-year recruitment period, and 7,858 patients agreed to enroll. Early clinical and demographic features of stroke patients and six multifaceted functional assessment scores measured from 7 days to 24 months after stroke onset were used as input variables. K-means clustering analysis was performed, and prediction models were generated and validated using machine learning. Results: A total of 5,534 stroke patients (4,388 ischemic and 1,146 hemorrhagic; mean age 63·31 ± 12·86; 3,253 [58.78%] male) completed functional assessments 24 months after stroke onset. Through K-means clustering, ischemic stroke (IS) patients were clustered into five groups and hemorrhagic stroke (HS) patients into four groups. Each cluster had distinct clinical characteristics and functional recovery patterns. The final prediction models for IS and HS patients achieved relatively high prediction accuracies of 0.926 and 0.887, respectively. Conclusions: The longitudinal, multi-dimensional, functional assessment data of first-time stroke patients were successfully clustered, and the prediction models showed relatively good accuracies. Early identification and prediction of long-term functional outcomes will help clinicians develop customized treatment strategies. [ABSTRACT FROM AUTHOR]

Orthostatic tremor (OT) is an uncommon progressive movement disorder that involves a leg tremor when standing or weight bearing. Additionally, OT can accompany other medical or neurodegenerative disorders. In this article, we report an unusual case of OT after trauma in an 18-year-old male patient whose symptoms of OT have been resolved after a multimodal therapeutic approach, including botulinum toxin injection. Surface electromyography, including a tremor recording, was used for the diagnosis of OT. The patient completely recovered after the rehabilitation. A comprehensive rehabilitative treatment is required in the management of OT as the patient's quality of life is greatly affected. [ABSTRACT FROM AUTHOR]

Objective To test the hypothesis that a longer duration of phase II cardiac rehabilitation is required to recover the exercise capacity of elderly patients compared to younger patients. Methods We retrospectively reviewed and analyzed the medical records of patients who were referred to our cardiac rehabilitation (CR) center and underwent percutaneous coronary intervention for acute myocardial infarction (AMI). A total of 70 patients were enrolled who underwent an exercise tolerance test (ETT) 3 weeks after the occurrence of an AMI (T0), 6 weeks after the first ETT (T1), and 12 weeks after the first ETT (T2). Patients older than 65 years were assigned to the elderly group (n=24) and those aged 65 years and younger to the younger group (n=46). Both groups performed center-based or home-based CR for 12 weeks (3 times per week and 1 session per day). Exercise intensity for each individual was based on the target heart rate calculated by the Karvonen formula. The change in maximal metabolic equivalents (METmax) of the two groups was measured at each assessment point (T0, T1, and T2) to investigate the recovery of exercise capacity. Results The younger group showed improvement in METmax between T0 and T1. However, METmax of the elderly group showed no significant improvement between T0 and T1. The exercise capacity, measured with METmax, of all groups showed improvement between T0 and T2. Conclusion Elderly patients with AMI need a longer duration of CR (>6 weeks) than younger patients with AMI. [ABSTRACT FROM AUTHOR]

Objective To compare a center-based cardiac rehabilitation (CR) program with a home-based CR program in terms of improving obesity related index and cardiopulmonary exercise capacity after the completing a phase II CR program. Methods In this study, there were seventy-four patients with acute myocardial infarction after percutaneous coronary intervention who were analyzed. Patients with mild to moderate risk (ejection fraction >40%) were included in the group. The patients underwent an exercise tolerance test by measurement of the modified Bruce protocol at three assessment points. Those in the center-based CR group participated in a 4-week training program with electrocardiography monitoring of the patient's progress and results, while those patients who were in the home-based CR group underwent self-exercise training. We measured the obesity related indices such as body mass index, fat free mass index (FFMI), and cardiopulmonary exercise capacity including peak oxygen consumption (VO2max), metabolic equivalents (METs), heart rate, resting systolic blood pressure and the diastolic blood pressure of the participants and noted the results. Results Of the 74 patients, 25 and 49 participated in the center-based and home-based CR programs, respectively. Both groups showed significant improvement in VO2max and METs at 1-month and 6-month follow-up. However, FFMI was significantly improved only in the center-based CR group after 1 month of the phase II CR. Conclusion Both groups identified in the study showed significant improvement of VO2max and METs at 1-month and 6-month follow-up. However, there was no significant difference in the intergroup analysis. A significant improvement of FFMI was seen only in the center-based CR group after phase II CR. [ABSTRACT FROM AUTHOR]

Objective To determine whether heart rate recovery (HRR) following an exercise tolerance test (ETT) is correlated with a changing ratio of peak oxygen consumption (VO2) and maximal metabolic equivalents (METmax). Methods A total of 60 acute myocardial infarction (AMI) patients who underwent ETT at both assessment points - 3 weeks (T0) after the AMI attack and 3 months after T0 (T1) were included. After achieving a peak workload, the treadmill was stopped with a 5-minute cooldown period, and the patients recovered in a comfortable and relaxed seated position. HRR was defined as the difference between the maximal heart rate (HRmax) and the HR measured at specific time intervals - immediately after the cool down period (HRR-0) and 3 minutes after the completion of the ETT (HRR-3). Results HRR-0 and HRR-3 increased over time, whereas VO2max and METmax did not show significant changes. There was a positive correlation between HRR at T0 and the exercise capacity at T0. HRR at T0 also showed a positive correlation with the exercise capacity at T1. There was no significant correlation between HRR measured at T0 and the change in the ratio of VO2max and METmax, as calculated by subtracting VO2max and METmax obtained at T0 from those obtained at T1, divided by VO2max at T0 and multiplied by 100. Conclusion Post-exercise HRR measured at 3 weeks after the AMI onset can reflect the exercise capacity 3 months after the first ETT. However, it may be difficult to correlate post-exercise HRR at T0 with the degree of increase in cardiopulmonary exercise capacity in patients with AMI. [ABSTRACT FROM AUTHOR]

Background: Scalp acupuncture (SA) and repetitive transcranial magnetic stimulation (rTMS) are effective for treating cerebral infarction. This study aims to examine the efficacy and safety of SA and electromagnetic convergence stimulation (SAEM-CS), which was developed through collaboration between conventional medical physicians and doctors who practice traditional Korean medicine. SAEM-CS was designed to improve function in patients with cerebral infarction, compared to the improvement after conventional stroke rehabilitation, SA, and rTMS therapeutic approaches. Methods/design: This study is a prospective, outcome assessor-blinded, randomized controlled clinical trial with a 1:1:1:1 allocation ratio. Participants with motion or sensory disabilities caused by a first-time cerebral infarction (n =60) that had occurred within 1 month of the study onset will be randomly assigned to control, SA, rTMS, or SAEMCS groups. All groups will receive two sessions of conventional rehabilitation treatment per day. The SA group will receive SA on the upper limb area of MS6 and MS7 (at the lesional hemisphere) for 20 min, the rTMS group will receive low-frequency rTMS (LF-rTMS) treatment on the hot spot of the M1 region (motor cortex at the contralesional hemisphere) for 20 min, and the SAEM-CS group will receive LF-rTMS over the contralesional M1 region hot spot while receiving simultaneous SA stimulation on the lesional upper limb area of MS6 and MS7 for 20 min. SA, rTMS, and SAEM-CS treatments will be conducted once/day, 5 days/week (excluding Saturdays and Sundays) for 3 weeks, for a total of 15 sessions. The primary outcome will be evaluated using the Fugl-Meyer Assessment, while other scales assessing cognitive function, activities of daily living, walking, quality of life, and stroke severity are considered secondary outcome measures. Outcome measurements will be conducted at baseline (before intervention), 3 weeks after the first intervention (end of intervention), and 4 weeks after intervention completion. Discussion: This study aims to explore the efficacy and safety of SAEM-CS on cerebral infarction. Collaborative research combined traditional Korean and conventional medicines, which can be useful in developing new treatment technologies. [ABSTRACT FROM AUTHOR]
