Body ownership refers to the distinct sensation that our observed body belongs to us, which is believed to stem from multisensory integration. The rubber hand illusion (RHI) provides the most well-known evidence for this proposal: synchronous (but not asynchronous) stroking of a fake hand and a participant’s real hidden hand can induce a sense of ownership over the false limb. Whilst the RHI may interfere with object-directed action and alter motor cortical activity, it is not yet clear whether a sense of ownership over an artificial hand has functional consequences for movement production per se. As such, we performed two motion-tracking experiments (n=117) to examine the effects of the RHI on the reaction time, acceleration, and velocity of rapid index finger abduction. We also examined whether subjective components of the illusion and the associated changes in hand position sense (proprioceptive drift) were correlated with changes in the kinematic variables. We observed convincing evidence that the induction of the RHI did not alter any kinematic variables. Moreover, the subjective sensations of rubber hand ownership, referral of touch, and agency did not convincingly correlate with kinematic variables, and nor did proprioceptive drift, suggesting that changes in body representation elicited by the RHI may not influence basic movement. Whilst experiment 1 suggested that individuals reporting a greater sensation of the real hand disappearing performed movements with smaller acceleration and velocity following illusion induction, we did not replicate this effect in a second experiment, suggesting that these effects may be small or not particularly robust.

The rubber hand illusion describes a sense of embodiment over a fake hand induced by synchronous visuo-tactile stimulation. In Tourette Syndrome, the expression of involuntary tics and preceding premonitory sensations is associated with the perturbation of subjective feelings of self-control and agency. We compared responses to induction of the Rubber Hand Illusion in 23 adults with TS and 22 matched controls. Both TS and control participants reported equivalent subjective embodiment of the artificial hand: feelings of ownership, location, and agency were greater during synchronous visuo-tactile stimulation, compared to asynchronous stimulation. However, individuals with TS did not manifest greater proprioceptive drift during synchronous relative to asynchronous stimulation, an objective marker of embodiment observed in controls. We computed an ‘embodiment prediction error’ index from the difference between subjective embodiment and objective proprioceptive drift. This embodiment prediction error correlated with severity of premonitory sensations according to the Premonitory Urge for Tics Scale (PUTS). Feelings of ownership over the artificial hand also correlated with premonitory sensation severity, and feelings of agency with tic severity (YGTSS). Together our findings suggest that the subjective strength of bodily ownership, as measured by the rubber hand illusion, contributes to susceptibility to the premonitory sensations that are a precipitating factor in tics. These results also suggest that somatosensory neural pathways underpinning visuo-tactile integration are likely altered in TS and may interact with other sensory and motor systems to engender premonitory sensations and tics.
