Clinical Trial
Effect of Tai Chi Training on Plantar Loads during Walking in Individuals with Knee Osteoarthritis.
Tai Chi is an available method for the treatment of knee osteoarthritis (KOA). The impacts of Tai Chi on plantar loads of individuals with KOA are not fully understood. 46 participants with knee osteoarthritis were randomly assigned into the Tai Chi group (n = 23) or the control group (n = 23). The Tai Chi group attended a 6-month Tai Chi program, and the control group participated in a wellness education program. ⋯ However, there were significant declines in the peak pressure of the whole foot and the 2nd and 3rd metatarsophalangeal joints and maximum force of the heel in the control group. These results suggested that individuals with KOA might change the pattern of plantar loads during walking through Tai Chi, and plantar loads would be useful as a parameter to assess the effect of Tai Chi on knee osteoarthritis. This trial is registered with Clinical Trials: CHiCTR-TRC-13003264.

To evaluate the surgical efficacy of bone transport (Ilizarov technique) plus "shortening-lengthening," "flap surgery," and "open bone transport" as individualized treatments for traumatic composite tibial bone and soft tissue defects. ⋯ The Ilizarov technique yields satisfactory efficacy for composite tibial bone and soft tissue defects when combined with "shortening-lengthening technique," "flap surgery," and "open bone transport" with appropriate individualized treatment strategies.

Observational Study
Altered Gut Microbiota and Shift in Bacteroidetes between Young Obese and Normal-Weight Korean Children: A Cross-Sectional Observational Study.
Emerging data suggest that the gut microbiome is related to the pathophysiology of obesity. This study is aimed at characterizing the gut microbiota composition between obese and normal-weight Korean children aged 5-13. We collected fecal samples from 22 obese and 24 normal-weight children and performed 16S rRNA gene sequencing using the Illumina MiSeq platform. ⋯ Phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) analysis revealed that the functions related to carbohydrate and lipid metabolism in the microbiota were more enriched in the normal-weight group than in the obese group. Our data may contribute to the understanding of the gut microbial structure of young Korean children in relation to obesity. These findings suggest that Bacteroidetes may be a potential therapeutic target in pediatric obesity.

Randomized Controlled Trial
Efficacy of Combination Therapies on Neck Pain and Muscle Tenderness in Male Patients with Upper Trapezius Active Myofascial Trigger Points.
Myofascial pain syndrome, thought to be the main cause of neck pain and shoulder muscle tenderness in the working population, is characterized by myofascial trigger points (MTrPs). This study aimed to examine the immediate and short-term effect of the combination of two therapeutic techniques for improving neck pain and muscle tenderness in male patients with upper trapezius active MTrPs. This study was a pretest-posttest single-blinded randomized controlled trial. ⋯ The intergroup analysis revealed significant differences among groups A, B, and C in VAS and PPT at Po (VAS-Po: F = 13.88, p=0.0001; PPT-Po: F = 17.17, p=0.0001) and even after 2 weeks of follow-up (VAS-Fo: F = 222.35, p=0.0001; PPT-Fo: F = 147.70, p=0.0001). Cohen's d revealed a significant treatment effect size within all groups except group C (only significant for VAS-Po-VAS-Pr: mean difference = 1.33, p < 0.05, d = 1.09); however, it showed a maximum effect size in group A for its variables (VAS-Fo-VAS-Pr: mean difference = 5.27, p=0.01, d = 4.04; PPT-Fo-PPT-Pr: mean difference = 2.14, p < 0.01, d = 3.89). Combination therapies (MET plus ICT) showed immediate and short-term (2-week follow-up) improvements in neck pain and muscle tenderness in male patients with upper trapezius active MTrPs.

Observational Study
Translation and Validation of the Korean Version of the Postoperative Quality of Recovery Score QoR-15.
Quality of recovery after anesthesia is an important measure of the early postoperative health status of patients. The Quality of Recovery-15 (QoR-15) questionnaire is a self-rated questionnaire used to assess the quality of postoperative recovery. This study is aimed at translating and validating the Korean version of QoR-15 (QoR-15K). ⋯ The mean ± standard deviation time to complete QoR-15K was 138.1 ± 30.7 s. QoR-15K was rated more than adequate on the COnsensus-based Standards for the selection of health Measurement INstruments checklist. In conclusion, QoR-15K shows acceptable validity, reliability, responsiveness, and clinical feasibility and may help evaluate postoperative quality of recovery in Korean populations.
