Assessment of the financial gaps in cardiothoracic surgery in Africa.

Objectives: This study identified the challenges to financing cardiothoracic surgical care in Africa, highlighting the present state of funding and proffering probable solutions to adequate and effective funding in the region.

Methods: In a literature review, the authors elaborated key points, such as areas of financial funding in cardiothoracic surgery; barriers to appropriate allocation of financial resources for cardiothoracic surgery in Africa; and the needs and available resources for cardiothoracic surgery in Africa. Multiple search engines and databases were used, including but not limited to PubMed, Medline, Cochrane, Scopus and Google Scholar.

Active lower limb orthosis with one degree of freedom for people with paraplegia.

The main challenges of designing devices for paraplegic walking can be summarized into three groups, stability and comfort, high efficiency or low energy consumption, dimensions and weight. A new economical device for people with paraplegia which tackles all problems of the three groups is introduced in this paper. The main idea of this device is based on HALO mechanism.

Gait generation for powered Hip-Ankle-Linkage-Orthosis.

A hip-knee-ankle-foot orthotic system called `HALO'(Hip and Ankle Linked Orthosis) for paraplegic walking has been developed in our previous study. Each ankle joint of the HALO system is linked with a medial single joint via a wire which allows both feet of the orthosis to stay always parallel to the floor during walking and assists swinging the leg. The tests of the HALO system demonstrated that it allows smoother walking and easy don/doff.

A new powered orthosis with hip and ankle linkage for paraplegics walking.

Several types of hip-knee-ankle-foot orthotic systems have been proposed for paraplegic walking during these decades. Hip and ankle linked orthosis (HALO) is compact one in those orthoses, which seeks to achieve a smoother-movement and user-easiness on its don/doff in paraplegic walking. The idea of HALO is to link two ankle joints with medial single joint via wires so that the orthosis keeps both feet always parallel to the floor while walking and assist the swinging of the leg.

Robot-aided motion planning for knee joint rehabilitation with two robot-manipulators.

In this paper, we propose a simultaneous design method of motion and external force trajectories for knee joint rehabilitation based on the biomechanical analysis of the lower limb. In this method we assume to use two robots manipulators which provide forces and moments at shank and thigh. We developed a 7 degree of freedom musculoskeletal model of lower limb with 19 muscles.
