Design of active orthoses for a robotic gait rehabilitation system

A. C. VILLA-PARRA,L. BROCHE,D. DELISLE-RODRÍGUEZ,R. SAGARÓ,T. BASTOS,A. FRIZERA-NETO

Frontiers of Mechanical Engineering 2015, Volume 10, Issue 3, Pages 242-254 doi: 10.1007/s11465-015-0350-1

Abstract:

An active orthosis (AO) is a robotic device that assists both human gait and rehabilitation therapy. This work proposes portable AOs, one for the knee joint and another for the ankle joint. Both AOs will be used to complete a robotic system that improves gait rehabilitation. The requirements for actuator selection, the biomechanical considerations during the AO design, the finite element method, and a control approach based on electroencephalographic and surface electromyographic signals are reviewed. This work contributes to the design of AOs for users with foot drop and knee flexion impairment. However, the potential of the proposed AOs to be part of a robotic gait rehabilitation system that improves the quality of life of stroke survivors requires further investigation.

3D Printing Hip Prostheses Offer Accurate Reconstruction, Stable Fixation, and Functional Recovery for Article

Yongqiang Hao, Lei Wang, Wenbo Jiang, Wen Wu, Songtao Ai, Lu Shen, Shuang Zhao, Kerong Dai

Engineering 2020, Volume 6, Issue 11, Pages 1285-1290 doi: 10.1016/j.eng.2020.04.013

Abstract:

Complicated and large acetabular bone defects present the main challenges and difficulty in the revision of total hip arthroplasty (THA). This study aimed to explore the advantages of three-dimensional (3D) printing technology in the reconstruction of such acetabular bone defects. We retrospectively analyzed the prognosis of four severe bone defects around the acetabulum in three patients who were treated using 3D printing technology. Reconstruction of bone defect by conventional methods was difficult in these patients. In this endeavor, we used radiographic methods, related computer software such as Materialise's interactive medical image control system and Siemens NX software, and actual surgical experience to estimate defect volume, prosthesis stability, and installation accuracy, respectively. Moreover, a Harris hip score was obtained to evaluate limb function. It was found that bone defects could be adequately reconstructed using a 3D printing prosthesis, and its stability was reliable. The Harris hip score indicated a very good functional recovery in all three patients. In conclusion, 3D printing technology had a good therapeutic effect on both complex and large bone defects in the revision of THA. It was able to achieve good curative effects in patients with large bone defects.
