This article proposes a novel shift automation mechanism for an automated manual transmission (AMT). The development of an automated manual transmission is currently being paid considerable attention by vehicle manufacturers, with the prospects of combining the comfort of an automatic transmission and the high efficiency of a manual transmission. In order to automate the shift mechanism of a manual transmission, the proposed shift automation mechanism consists of two electric motors, cross shaped pinion gears, rack type shift rails, and a ball splined hollow shaft. First we describe the shift mechanism and operating principles of a manual transmission to investigate important design criteria for the shift automation device. And a new shift automation mechanism is described with its structure, elements, and operating principles in detail. Using a conventional manual transmission, we develop a full three-dimensional CAD model of an AMT which includes main components of the manual transmission and the designed shift automation mechanism. Finally we investigate the operating performances and feasibility of the designed AMT by a dynamic analysis.

Objectives : To evaluate the evidence supporting the effectiveness of Chuna manual therapy for functional dyspepsia. Methods : We conducted search across the 3 electronic databases (Pubmed, CAJ and Oasis) to find all of randomized controlled clinical trials(RCTs) that used Chuna manual therapy as a treatment for functional dyspepsia. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. Results : Thirteen RCTs met our inclusion criteria. The meta-analysis showed positive results for the use of Chuna manual therapy combined with medication treatments in terms of the efficacy rate when compared to medication treatments alone. Positive results were also obtained, in terms of the efficacy rate, when comparing Chuna manual therapy combined with medication plus specific electromagnetic therapy to medication treatments alone. Conclusions : Our systematic review found encouraging but limited evidence of Chuna manual therapy for functional dyspepsia. However, to obtain stronger evidence without the drawbacks of trial design and the quality of studies, we recommend sham-controlled RCTs or comparative effectiveness research to test the effectiveness of Chuna manual therapy.

Objectives : This study aimed to systematically and comprehensively review controlled clinical trials on the effectiveness and safety of Chuna Manual Therapy for stroke. Methods : By October 7, 2019, three core databases and three domestic databases were searched. Seven major academic journals on the related field were also hand-searched. Methodological quality of the included studies was evaluated using the Cochrane risk of bias tool. Meta-analysis was conducted and the quality of its evidence was assessed using the GRADE methodology. Results : Five articles met the eligibility criteria. The results of most of included studies were in favor of Chuna Manual Therapy. No study described any adverse events during or after the clinical trials. Meta-analysis of three eligible studies showed that the pre- and post-treatment scores on the Modified Barthel Index (mean difference 8.00, 95% confidence interval 0.26 to 15.74) and Berg Balance Scale (mean difference 3.57, 95% confidence interval 0.64 to 6.51) of the Chuna-treated group were significantly different, but only marginally higher than those of the non-treatment group. Thus, the level of evidence gathered from these studies was assessed to be low. Conclusions : Based on current available evidence, any confirmative conclusions cannot be made on the effectiveness and safety of Chuna Manual Therapy for stroke because of the small sample size, low methodological quality, presence of statistical heterogeneity, and missing safety information. More rigorously designed large-scale multi-center studies are needed to establish more specific and credible evidence to support or oppose the use of Chuna Manual Therapy for stroke.

Objectives This study aimed to assess the efficacy and safety of manual therapy in patients with failed back surgery syndrome (FBSS). Methods We searched eight electronic databases from October 2022 and only selected randomized controlled trials (RCTs) reporting outcomes for manual therapy in FBSS patients. Included studies were analyzed qualitatively. Results A total of twelve RCTs were included and three studies were meta-analyzed. Manual therapy combined with exercise demonstrated more favorable outcomes in terms of pain reduction compared to exercise therapy only (P<0.01). Some studies reported that manual therapy resulted in low efficacy, while some studies reported that specific manual techniques have a significant effect in pain relief. We, therefore, conclude that several studies have a high risk of bias. Conclusions Findings suggest that manual therapy is a safe and non-invasive, promising option for managing FBSS. However, manual therapy is not the best option in all circumstances; thus, this should be selectively applied by a well-trained practitioner. Further studies such as well-designed, risk-controlled RCTs are required to gain stronger evidence.
