“…For the haptic community, learning how these tools are integrated in the brain's body representation may aid the design of ergonomic and usable interfaces and could enable a more objective assessment of their usability (Lee et al 2005;Santos-Carreras et al 2011). The results of the present studies show that methodologies from cognitive neuroscience (i.e., the crossmodal congruency task) can be used to investigate whether and how visual and tactile cues are integrated when using robotic technology.…”

“…The results of the present studies show that methodologies from cognitive neuroscience (i.e., the crossmodal congruency task) can be used to investigate whether and how visual and tactile cues are integrated when using robotic technology. Up to now, human factors in robotics, especially in surgical robotics, have been quantified by means of questionnaires, surveys or performance-based studies (Prasad et al 2002;Lee et al 2005;Santos-Carreras et al 2011). These studies focused on performance measures, but they neglected the basic and quantifiable change of multisensory integration due to tool use (Tan et al 2010).…”

Force feedback facilitates multisensory integration during robotic tool use

In the first experiment it was found that tool-use training with force feedback facilitates multisensory integration of signals from the tool, as reflected in a stronger crossmodal congruency effect with the force feedback training compared to training without force feedback and to no training. The second experiment extends these findings by showing that training with realistic online force feedback resulted in a stronger crossmodal congruency effect compared to training in which force feedback was delayed. The present study highlights the importance of haptic information for multisensory integration and extends findings from classical tool-use studies to the domain of robotic tools. We argue that such crossmodal congruency effects are an objective measure of robotic tool integration and propose some potential applications in surgical robotics, robotic tools, and human-tool interaction.

“…These systems provide three-dimensional stereoscopic vision, increased degrees-of-freedom of movement at the tip of the instrument, the elimination of tremor, and selectable motion scaling. These features all combine to allow potentially more precision than either LAP or traditional open surgery [17]. LAP may also lead to an increased incidence of digital neuropraxia and other musculoskeletal injuries [18][19][20] to the surgeon due to pressure on the digital nerves at the handles of the instruments.…”

An assessment of the physical impact of complex surgical tasks on surgeon errors and discomfort: a comparison between robot‐assisted, laparoscopic and open approaches

ObjectivesTo evaluate, in a simulated suturing task, individual surgeons' performance using three surgical approaches: open, laparoscopic and robot-assisted. Subjects and MethodsSix urological surgeons made an in vitro simulated vesico-urethral anastomosis. All surgeons performed the simulated suturing task using all three surgical approaches (open, laparoscopic and robot-assisted). The time taken to perform each task was recorded. Participants were evaluated for perceived discomfort using the self-reporting Borg scale. Errors made by surgeons were quantified by studying the video recording of the tasks. Anastomosis quality was quantified using scores for knot security, symmetry of suture, position of suture and apposition of anastomosis. ResultsThe time taken to complete the task by the laparoscopic approach was on average 221 s, compared with 55 s for the open approach and 116 s for the robot-assisted approach (ANOVA, P < 0.005). The number of errors and the level of self-reported discomfort were highest for the laparoscopic approach (ANOVA, P < 0.005). Limitations of the present study include the small sample size and variation in prior surgical experience of the participants. ConclusionsIn an in vitro model of anastomosis surgery, robot-assisted surgery combines the accuracy of open surgery while causing lesser surgeon discomfort than laparoscopy and maintaining minimal access.

“…Multiplying the weighted scores gives a single figure: the strain index (71,72). Comparison of the index with RULA has shown a limited correspondence with respect to the identification of risks (62,73). The correspondence of the strain index with ACGIH HAL (see below) was moderate, but the former gave generally higher risk estimates than the latter (74,75).…”

Objectives This systematic review aimed to identify published observational methods assessing biomechanical exposures in occupational settings and evaluate them with reference to the needs of different users. MethodsWe searched scientific databases and the internet for material from 1965 to September 2008. Methods were included if they were primarily based on the systematic observation of work, the observation target was the human body, and the method was clearly described in the literature. A systematic evaluation procedure was developed to assess concurrent and predictive validity, repeatability, and aspects related to utility. At least two evaluators independently carried out this evaluation. ResultsWe identified 30 eligible observational methods. Of these, 19 had been compared with some other method(s), varying from expert evaluation to data obtained from video recordings or through the use of technical instruments. Generally, the observations showed moderate-to-good agreement with the corresponding assessments made from video recordings; agreement was the best for large-scale body postures and work actions. Postures of wrist and hand as well as trunk rotation seemed to be more difficult to observe correctly. Intra-and inter-observer repeatability were reported for 7 and 17 methods, respectively, and were judged mostly to be moderate or good.good. . ConclusionsWith training, observers can reach consistent results on clearly visible body postures and work activities. Many observational tools exist, but none evaluated in this study appeared to be generally superior. When selecting a method, users should define their needs and assess how results will influence decision-making.
