The cognitive advantage of imagined spatial transformations of the human body over that of more unfamiliar objects (e.g., Shepard-Metzler [S-M] cubes) is an issue for validating motor theories of visual perception. In 6 experiments, the authors show that providing S-M cubes with body characteristics (e.g., by adding a head to S-M cubes to evoke a posture) facilitates the mapping of the cognitive coordinate system of one's body onto the abstract shape. In turn, this spatial embodiment improves object shape matching. Thanks to the increased cohesiveness of human posture in people's body schema, imagined transformations of the body operate in a less piecemeal fashion as compared with objects (S-M cubes or swing-arm desk lamps) under a similar spatial configuration, provided that the pose can be embodied. If the pose cannot be emulated (covert imitation) by the sensorimotor system, the facilitation due to motoric embodiment will also be disrupted.

Background: Early detection and response to patient deterioration influence patient prognosis. Nursing education is therefore essential. The objective of this randomized controlled trial was to compare the respective educational value of simulation by gaming (SG) and a traditional teaching (TT) method to improve clinical reasoning (CR) skills necessary to detect patient deterioration. Methods: In a prospective multicenter study, and after consent, 2nd year nursing students were randomized into two groups: Simulation by gaming “SG”: the student played individually with a serious game consisting of 2 cases followed by a common debriefing with an instructor; Traditional Teaching “TT”: the student worked on the same cases in text paper format followed by a traditional teaching course with a PowerPoint presentation by an instructor. CR skill was measured by script concordance tests (80 SCTs, score 0–100) immediately after the session (primary outcome) and on month later. Other outcomes included students’ satisfaction, motivation and professional impact. Results: One hundred forty-six students were randomized. Immediately after training, the SCTs scores were 59 ± 9 in SG group (n = 73) and 58 ± 8 in TT group (n = 73) (p = 0.43). One month later, the SCTs scores were 59 ± 10 in SG group (n = 65) and 58 ± 8 in TT group (n = 54) (p = 0.77). Global satisfaction and motivation were highly valued in both groups although significantly greater in the SG group (p < 0.05). The students declared that the training course would have a positive professional impact, with no difference between groups. Conclusions: In this study assessing nursing student CR to detect patient deterioration, no significant educational difference (SCT), neither immediate nor 1 month later, was observed between training by SG and the TT course. However, satisfaction and motivation were found to be greater with the use of SG. Trial registration: ClinicalTrials.gov; NCT03428269. Registered 30 january 2018.

Although there is evidence that spinal manipulative therapy (SMT) can reduce pain, the mechanisms involved are not well established. There is a need to review the scientific literature to establish the evidence-base for the reduction of pain following SMT.
