  • PURPOSE. This study aimed to evaluate the effect of two different implant-abutment connection structures with identical implant design on peri-implant bone level. MATERIALS AND METHODS. This clinical study was a patient-blind randomized controlled trial following the CONSORT 2010 checklists. This trial was conducted in 24 patients recruited between March 2013 and July 2015. Implants with internal friction connection were compared to those with external hex connection. One implant for each patient was installed, replacing the second molar. Implant-supported crowns were delivered at four months after implant insertion. Standardized periapical radiographs were taken at prosthesis delivery (baseline), and one year after delivery. On the radiographs, distance from implant shoulder to first bone-to-implant contact (DIB) and peri-implant area were measured, which were the primary and secondary outcome, respectively. RESULTS. Eleven external and eleven internal implants were analyzed. Mean changes of DIB from baseline to 1-year postloading were 0.59 (0.95) mm for the external and 0.01 (0.68) mm for the internal connection. Although no significant differences were found between the two groups, medium effect size was found in DIB between the connections (Cohen's d = 0.67). CONCLUSION. Considering the effect size in DIB, this study suggested the possibility of the internal friction connection structure for more effective preservation of marginal bone.

  • Background: The study investigated virtual reality (VR) immersion in alleviating procedure-related pain in patients with chronic pain undergoing fluoroscopy-guided minimally-invasive intervention in a prone position at an outpatient clinic. Methods: In this prospective randomized controlled study, 38 patients undergoing lumbar sympathetic ganglion block were randomized into either the VR or the control group. In the VR group, procedure-related pain was controlled via infiltration of local anesthetics while watching a 30-minute VR hypnotic program. In the control group, the skin infiltration alone was used, with the VR device switched off. The primary endpoint was an 11-point score on the numerical rating scale, indicating procedure-related pain. Patients' satisfaction with pain control, anxiety levels, the need for additional local anesthetics during the procedure, hemodynamic stability, and any adverse events were assessed. Results: Procedure-related pain was significantly lower in the VR group (3.7 ± 1.4) than in the control group (5.5 ± 1.7; P = 0.002). Post-procedural anxiety was lower in the VR group than in the control group (P = 0.025), with a significant reduction from pre-procedural anxiety (P < 0.001). Although patients' satisfaction did not differ significantly (P = 0.158) between the groups, a higher number of patients required additional local anesthetics in the control group (n = 13) than in the VR group (n = 4; P = 0.001). No severe adverse events occurred in either group during the study. Conclusions: VR immersion can be safely used as a novel adjunct to reduce procedural pain and anxiety during fluoroscopic pain intervention.

  • This study aimed to review clinical studies about Acupotomy used for Knee Osteoarthritis. We searched the following 12 online databases (KISS, NDSL, RISS, OASIS, Earticle, Kmbase, MEDLINE/Pubmed, Cochrane library, Ebscohost, Ovid, CNKI, Wanfang), to find randomized controlled trials that used Acupotomy for knee osteoarthritis. The methodological quality of randomized controlled trials were assessed by using the Cochrane risk of bias tool and meta-analyses were performed. 16 randomized controlled trials were included. Total number of patients was 1169. The average duration of treatment was 3.14 weeks and most of the patients were treated once a week. The major treatment sites were ligaments, muscles, and tender nodules and the most used evaluation tool was the efficiency. We selected 4 studies and meta-analyzed them. All of the studies performed Acupotomy+sodium hyaluronate injection as a treatment group, and sodium hyaluronate injection as a control group. Meta-analysis showed positive results for Acupotomy+sodium hyaluronate injection in terms of efficiency rate compared to sodium hyaluronate injection. Also Meta-analysis showed positive results for Acupotomy+sodium hyaluronate injection in terms of WOMAC (pain, stiffness, function) compared to sodium hyaluronate injection. In this study, we reviewed studies about Acupotomy used for knee osteoarthritis. The studies showed that Acupotomy can significantly effective on knee osteoarthritis. But according to Cochrane Risk of Bias (RoB) evaluation method, most of the study's risk of bias was unclear. Threrefore, more high-quality studies will be needed.

  • Objectives Domestic acupuncture research is being actively conducted in various fields. The aim of this study is to systematically analyze the current acupuncture randomized controlled trials (RCTs) conducted on healthy volunteers. Methods We searched RCTs by the search terms of (acupuncture & random & healthy) in 10 electronic databases and related journals. Then, we analyzed the characteristics and assessed the risk of bias by Cochrane tool. Results Finally, 49 acupuncture RCTs on health volunteers were included in our analysis. The purpose of research could be classified into five major categories: (1) checking the effects on physiological function, (2) comparing the effects of different acupuncture/acupuncture methods, (3) a study confirming improvement after inducing a specific condition, (4) a sham acupuncture study, and (5) a comparison of acupuncture sense. The Cochrane risk of bias was generally high, especially only 1 trial adopted allocation concealment (1/49, 2.0%) and 9 ones with assessor blinding (9/49, 18.4%). Conclusions Acupuncture RCTs in healthy subjects have confirmed various effects in various age/sex groups. However the research quality should be updated for future clinical research and to draw clear conclusion within rigorous methodology.

  • Objectives The objective of this study was to assess the effectiveness of acupotomy for carpal tunnel syndrome. Methods Based on seven domestic and foreign databases. We analyzed the randomized controlled trials using acupotomy for carpal tunnel syndrome. The treatment group was treated with acupotomy and the control group was no restrictions on treatment methods. Results In this study, the effect of acupuncture treatment for carpal tunnel syndrome was investigated. Each study reported that acupotomy could be an effective treatment for carpal tunnel syndrome. However, as a result of meta-analysis of Levine carpal tunnel syndrome questionnaire scores, visual analog scale, and sensory nerve conduction velocity, the results were more clinically significant than those of the control group. Due to the small number of randomized controlled trial studies and the nature of acupotomy treatment, blinding of interventions was impossible, resulting in a high risk of bias. Conclusions In this regard, it is thought that well-planned randomized controlled studies on patients with carpal tunnel syndrome are needed in the future to secure the clinical evidence for acupotomy treatment.

  • Background: The aim of this randomized controlled pilot study was to determine the effect of trunk training in wheelchair on fall efficacy, fall risk and activities of daily living in acute stroke patients. Design: Randomized controlled pilot trial. Methods: The study included 18 patients with acute stroke who were randomly allocated to an experimental group (EG) (n=9) and a control group (CG) (n=9). Patients in the EG group received general rehabilitation therapy combined with trunk training in wheelchair for 20min, whereas CG group received general rehabilitation therapy combined with bicycle training for 20min. Both groups performed the exercise 5 times a week for 3 weeks. Outcomes were assessed using Korean-Fall Efficacy Scale (K-FES), Fullerton Advanced Balance Scale (FAB) and Korean-Modified Barthel Index (K-MBI). Results: After 3 weeks of training, both groups showed significantly improved K-FES, FAB and K-MBI (p<.05 in both groups). However, the K-FES, FAB and K-MBI in the experimental group was significantly improving than in the control group (p<.05). Conclusion: These findings indicate that trunk training in wheelchair may be effective at decreasing fall risk and improving activities of daily living in acute stroke patients. Therefore, trunk training in wheelchair may be recommended as an intervention in reducing the incidence of fall risk in acute stroke patient.

  • Objectives : This study aims to review randomized controlled trials on acupuncture for shoulder pain according to Jadad Scale and revised STRICTA. Methods : Seven electronic databases including PUBMED, SCOPUS, RISS were searched for randomized controlled trials (RCT) of acupuncture for shoulder pain. Results : 16 RCTs were included: 14 were published in English and 2 were published in Korean. According to Jadad scale, 15 RCTs had high quality. However, most of the studies could not meet the double blindness criteria. All RCTs meet 12.9 items on average in STRICTA. Conclusions : This systematic review shows four conclusions as follows. Traditional Chinese Medicine is often used in style of acupuncture. Spots of LI15, TE14, GB21 and LI11, stainless steel needle($0.3mm{\times}40mm$), 20 retention time, manual stimulation, $Deqi$, and 2 times a week treatment (total 12) are often used. Double-blinded clinical trials needs to be conducted. It is controversial to use minimal acupunctures on controlled groups of RCTs on acupuncture for shoulder pain. Description about practitioner's background needs clarifying.
