“…First, we investigated a sample of young individuals (healthy university students); thus, our findings may not be generalized to older people (Goble et al, 2020 ) and those needing movement or postural rehabilitation. Second, because we applied a passive agent (without any active ingredient), it is still possible that placebo and nocebo instructions administered with an active placebo might have been more effective (de la Vega et al, 2017 ; Szabo et al, 2018 ). Third, we used an inert white cream, which in a previous study (Szabo et al, 2013 ) was perceived as less effective than ingestible fictive agents.…”

Placebo and nocebo effects could influence the perceived, actual, or both postural stabilities. Therefore, this experiment examined whether postural stability is susceptible to placebo and nocebo effects. Driven by expectations, these cognitions could influence the motor stability of people in physical rehabilitation and those with motion instability. We randomly assigned 78 participants to a placebo, nocebo, or control group. Then, we applied a sham sports cream with positive, negative, or neutral instructions about its impact on balance. Next, we tested postural stability with a modified version of the Modified Clinical Test of Sensory Interaction in Balance, including standard, proprioceptive, visual, and vestibular tests before and after the intervention. Further, we measured expected and perceived performance with visual analog scales and assessed trait anxiety, change in state anxiety, optimism, holistic thinking, persistence, and cooperation with questionnaires. The intervention did not affect actual test performances; similarly, trait and state variables and expectations did not have an impact. Furthermore, the experimental manipulation and trait and state variables did not significantly affect perceived performance. However, the association between expectation and perceived performance was strong (ϱ = 0.627, p < 0.001). These findings suggest that postural stability is not susceptible to placebo and nocebo influences. Still, there is a dissociation between objective and subjective performance, showing that expectations impact perceived but not actual performance, which could fuel motivation in rehabilitation settings.

“…For example, aging considerably deteriorates postural stability (Goble et al, 2020). Second, because we applied a passive agent (without any active ingredient), it is still possible that placebo and nocebo instructions can influence the effect of an active agent, such as the information-effect interaction (de la Vega Szabo et al, 2018). Third, to maintain a non-invasive protocol, we used an inert white cream, which in a previous study (Szabo et al, 2013) was less efficient than ingestible fictive agents.…”

Different aspects of motor performance were shown to be malleable to placebo and nocebo influences. However, there are equivocal findings too, and in some cases, only perceived but not actual performance was impacted. Therefore, the present laboratory investigation aimed to study if postural stability is susceptible to placebo and nocebo effects. Driven by expectations, these effects could affect the motor stability of the elderly and people with motion instability.Participants (N=78) were randomized to a placebo, nocebo, or control group. We applied a sham sports cream with different (positive, negative, or neutral) instructions about its impact on postural stability. A modified version of the Modified Clinical Test of Sensory Interaction in Balance was used to assess actual postural stability with four different test types (standard, proprioceptive, visual, vestibular) before and after the intervention. Expected and perceived performance was measured with visual analog scales. We also assessed trait anxiety, the change in the state anxiety, optimism, holistic thinking, persistence, and the motivation to cooperate with questionnaires. The experimental manipulation did not significantly affect actual performance, and the assessed psychological trait, state variables, and expectations did not have an impact. Similarly, the experimental manipulation and the assessed psychological trait and state variables did not significantly affect perceived performance. However, a strong association (rho=0.627, p<0.001) was found between expectation and perceived performance.Based on our findings, postural stability is not susceptible to placebo and nocebo influences. However, there is a dissociation between actual (objective) and perceived (subjective) performance, where expectations impact perceived, not actual performance.
