BACKGROUND: Muscle co-contraction is a strategy of increasing movement accuracy and stability employed in dealing with perturbation of movement. It is often seen in neuropathological populations. The direction of movement influences the pattern of co-contraction, but not all movements are easily achievable for populations with motor deficits. Manipulating the direction of the force instead, may be a promising rehabilitation protocol to train movement with use of a co-contraction reduction strategy...

Upper tract urothelial carcinoma is a relatively uncommon malignancy. The gold standard treatment for this type of neoplasm is an open radical nephroureterectomy with excision of the bladder cuff. This systematic review compares the perioperative and oncologic outcomes for the open surgical method with the alternative surgical management options of laparoscopic nephroureterectomy and robot-assisted nephroureterectomy (RANU). MEDLINE, EMBASE, PubMed, and Cochrane Library databases were searched using a sensitive search strategy...

BACKGROUND: Wearable assistive devices have demonstrated the potential to improve mobility outcomes for individuals with disabilities, and to augment healthy human performance; however, these benefits depend on how effectively power is transmitted from the device to the human user. Quantifying and understanding this power transmission is challenging due to complex human-device interface dynamics that occur as biological tissues and physical interface materials deform and displace under load, absorbing and returning power...

BACKGROUND: A bulla is a marked enlarged space within the parenchyma of the lung. Bullae may cause dyspnea by compressing healthy lung parenchyma and can cause a pneumothorax. Also, bullae are associated with malignancy, therefore surgical bullectomy is indicated on preventive basis. This case is unique and therefore valuable because of the remarkable presentation, innovative treatment and the spectacular improvement of lung function and socio-economic performance of the patient. CASE PRESENTATION: In this case report we describe the presentation, minimally invasive surgical treatment by means of a robot-assisted lobectomy and postoperative outcome of a young patient with a giant congenital bulla of the left upper lobe...

PURPOSE: Most evaluations of surgical workflow or surgeon skill use simple, descriptive statistics (e.g., time) across whole procedures, thereby deemphasizing critical steps and potentially obscuring critical inefficiencies or skill deficiencies. In this work, we examine off-line, temporal clustering methods that chunk training procedures into clinically relevant surgical tasks or steps during robot-assisted surgery. METHODS: Features calculated from the isogony principle are used to train four common machine learning algorithms from dry-lab laparoscopic data gathered from three common training exercises...

For many women with endometrial and cervical cancers, minimally invasive surgery represents an alternative standard of care to open abdominal procedures, with fewer complications, better postoperative quality of life, and overall lower cost. At the NCCN 22nd Annual Conference, Amanda N. Fader, MD, reviewed several minimally invasive strategies for treating gynecologic cancers, including conventional laparoscopy, robotic-assisted laparoscopy, sentinel lymph node technology, and single-port surgery; highlighted some of the contemporary literature on the role of these procedures; and explored some of the challenges and barriers to their successful performance...

We introduce an implantable intracardiac soft robotic right ventricular ejection device (RVED) for dynamic approximation of the right ventricular (RV) free wall and the interventricular septum (IVS) in synchrony with the cardiac cycle to augment blood ejection in right heart failure (RHF). The RVED is designed for safe and effective intracardiac operation and consists of an anchoring system deployed across the IVS, an RV free wall anchor, and a pneumatic artificial muscle linear actuator that spans the RV chamber between the two anchors...

The objective of this study is to perform an economic analysis and examine the influence of procedural volume of our hospital, evaluating the accounting systems of Robotic radical hysterectomy (RRH) vs Laparoscopic radical hysterectomy (TLRH) in patients with cervical carcinoma, due to the costs widely variable and lack in literature. Costs were collected prospectively, from March 2010 to March 2016. Direct costs were determined by examining the overall medical pathway for each type of intervention. 52 patients with cervical carcinoma, which were matched by age, body mass index, tumor size, International Federation of Gynecology and Obstetrics (FIGO) stage, comorbidity, previous neoadjuvant chemotherapy, histology type, and tumor grade to obtain homogeneous samples...

In order to harmonize robotic devices with human beings, the robots should be able to perceive important psychosomatic impact triggered by emotional states such as frustration or boredom. This paper presents a new type of biocooperative control architecture, which acts toward improving the challenge/skill relation perceived by the user when interacting with a robotic multimodal interface in a cooperative scenario. In the first part of the paper, open-loop experiments revealed which physiological signals were optimal for inclusion in the feedback loop...

BACKGROUND: In a patient with severe hemiplegia, the risk of the knee giving way is high during the early stage of gait exercise with an ankle-foot orthosis. However, use of a knee-ankle-foot orthosis has many problems such as large amount of assistance and compensatory motions. To resolve these problems, we have engaged in the development of the Gait Exercise Assist Robot (GEAR). OBJECTIVE: To evaluate the improvement efficiency of walk with GEAR in a stroke patient...

BACKGROUND: Robotic driven treatment plans targeting isolated joints of the upper limb have improved the sensorimotor condition of patients with stroke. Similar intensive efforts to allay lower limb gait impairment have not been so successful. In patients with stroke, targeted robot assisted training of the ankle joint, in a seated position, has demonstrated significant alterations in ankle stiffness and foot-ankle orientation at foot strike which may provide a new treatment option for gait impairment...

This paper presents the vibration pattern measurement of two tower-typed holonomic mobile robot prototypes: one based on a rigid mechanical structure, and the other including a passive suspension system. Specific to the tower-typed mobile robots is that the vibrations that originate in the lower part of the structure are transmitted and amplified to the higher areas of the tower, causing an unpleasant visual effect and mechanical stress. This paper assesses the use of a suspension system aimed at minimizing the generation and propagation of vibrations in the upper part of the tower-typed holonomic robots...
