Gait Training of Healthy Older Adults in a Sitting Position using the Wearable Robot to Assist Arm-swing Rhythm, WALK-MATE ROBOT.

Although various walking training robots have been developed and their effectiveness has been recognised, operating these robots requires the implementation of safety measures to avoid the risk of falling. This study aimed to confirm whether arm swing rhythm training in the sitting position using an arm swing rhythm-assisted robot, WMR, improved subsequent walking. Healthy older adults (N = 20) performed arm swing rhythm training in a sitting position for 1 min three times while being presented with tactile stimulation synchronised with the arm swing rhythm from a robot.

Electromigration Analysis for Interconnects Using Improved Graph Convolutional Network with Edge Feature Aggregation.

Electromigration (EM) is a critical reliability issue in integrated circuits and is becoming increasingly significant as fabrication technology nodes continue to advance. The analysis of the hydrostatic stress, which is paramount in electromigration studies, typically involves solving complex physical equations (partial differential equations, or PDEs in this case), which is time consuming, inefficient and not practical for full-chip EM analysis. In this paper, a novel approach is proposed, conceptualizing circuit interconnect trees as a graph within a graph neural network framework.

From materials to clinical use: advances in 3D-printed scaffolds for cartilage tissue engineering.

Osteoarthritis caused by articular cartilage defects is a particularly common orthopedic disease that can involve the entire joint, causing great pain to its sufferers. A global patient population of approximately 250 million people has an increasing demand for new therapies with excellent results, and tissue engineering scaffolds have been proposed as a potential strategy for the repair and reconstruction of cartilage defects. The precise control and high flexibility of 3D printing provide a platform for subversive innovation.

[Case-control study on poking closed reduction cannulated screw fixation and small incision reduction plate fixation for the treatment of calcaneal fractures].

Objective: To compare poking closed reduction cannulated screw fixation and small incision reduction plate fixation in treating calcaneal fractures.

Methods: Clinical data of 98 patients with calcaneal fractures were retrospectively analyzed from June 2015 and June 2018. According to fracture classification and treatment methods, the patients were divided into poking closed reduction cannulated screw fixation (group A) and small incision reduction plate fixation(group B).

Risedronate reduces postoperative bone resorption after cementless total hip arthroplasty: A systematic review and meta-analysis.

Objective: To examine the effects of risedronate for reducing periprosthetic bone loss after total hip arthroplasty (THA).

Methods: Two reviewers performed an electronic literature search for randomized controlled trial (RCTs) evaluating the risedronate in the management of periprosthetic bone loss after primary THA. The electronic databases include PubMed, Medline, Embase, Web of Science and the Cochrane Library from inception to January 2018.

[Clinical outcomes of total hip arthroplasty using Wagner SL revision stem in femoral intertrochanteric fractures for patients with old fracture or painful arthritis before injury].

Objective: To retrospectively study the clinical results of total hip arthroplasty(THA) using Wagner SL revision stem for patients with femoral intertrochanteric fracture.

Methods: From 2006 January to 2009 December, 29 consecutive patients with femoral intertrochanteric fractures were performed THA using Wagner SL revision stem and intertrochanteric reconstruction, including 18 males and 11 females with an average age of 49 years old ranging from 43 to 58. Among them, 8 cases were oboslete femoral intertrochanteric fractures and 21 cases were the intertrochanteric fractures with painful arthritis before injuries.

GSTP1 A>G polymorphism and chemosensitivity of osteosarcoma: A meta-analysis.

The association between GSTP1 A>G polymorphism and chemosensitivity of osteosarcoma is controversial according to previously published studies. We conducted this meta-analysis to further investigate the role of GSTP1 A>G genetic variation in response to chemotherapy resistance in patients with osteosarcoma. Using the electronic databases of Pubmed, Wanfang and CNIK were searched to find the studies related to the GSTP1 A>G polymorphism and chemosensitivity of osteosarcoma.

[EFFECTIVENESS OF COMBINED TENODESIS FOR PROXIMAL LESIONS OF BICEPS TENDON WITH MASSIVE ROTATOR CUFF TEAR BY ARTHROSCOPY].

Objective: To evaluate the effectiveness of the combined tenodesis for proximal lesions of biceps tendon with massive rotator cuff tear by arthroscopy.

Methods: Between January 2011 and June 2013, 48 patients with massive rotator cuff tear and proximal lesions of biceps tendon underwent combined tenodesis under arthroscopy, and the clinical data were retrospectively analyzed. Of 48 cases, 22 were male and 26 were female with an average age of 46 years (range, 35-59 years); 12 cases had clear history of trauma.

[MRI ainalysis of the pseudo-tears of the lateral meniscus of the knee and its clinical significance].

Objective: To determine the mechanism of pseudo-tears of the lateral meniscus caused by the transverse geniculate ligament (TL) and the miniscofemoral ligament(MFL) and to investigate a method to differentiate pseudo-tears from true tear of the lateral meniscus.

Methods: Form June 2012 to February 2014, MR examinations of 72 knees (44 left knees and 28 right knees) without tear of the lateral meniscus verified by arthroscopy were performed in the sagittal and coronal plane. There were 41 males and 31 females in the group, with an average age of 33.

[Diagnostic value of 3D-indirect magnetic resonance arthrography in detecting meniscal tears of the knees].

Objective: To explore the diagnostic value of 3D-indirectmagnetic resonance (MR) arthrography in detecting meniscustears of the knees.

Methods: Form January 2013 to January 2014, routine plain MR of the knees followed by the 3D-indirect MR arthrography was performed in 42 patients with suspected meniscal tears clinically. There were 31 males and 11 females, with an average age of 38.
