Agency is an important aspect of bodily self-consciousness, allowing us to separate own movements from those induced by the environment and to distinguish own movements from those of other agents. Unsurprisingly, theoretical frameworks for agency such as central monitoring are closely tied to computational models of sensorimotor control. Until recently agency research has largely focussed on goal-directed movements of the upper limbs. In particular, the influence of performance-related sensory cues and the relevance of prediction signals for agency judgements have been studied through a variety of spatio-temporal mismatches between movement and the sensory consequences of movement. However, agents often perform a different type of movement; highly automated movements that involve the entire body such as walking, cycling, and swimming with potentially different agency mechanisms. Here, we review recent work about agency for full-body movements such as gait, highlighting the effects of performance-related visual and auditory cues on gait agency. Gait movements differ from upper limb actions. Gait is cyclic, more rarely immediately goal-directed, and is generally considered one of the most automatic and unconscious actions. We discuss such movement differences with respect to the functional mechanisms of full-body agency and body-part agency by linking these gait agency paradigms to computational models of motor control. This is followed by a selective review of gait control, locomotion, and models of motor control relying on prediction signals and underlining their relevance for full-body agency.

“…Walking is a complex task involving the integration of locomotion, balance, and adaptation in an ever-changing environment (Armstrong, 1988;Blanc et al, 1999;Drew et al, 2004). However, the neuroscience of human upright gait is hampered by two main caveats.…”

“…On average participants' footsteps were separated by 613 ms, compatible with physiological data in healthy subjects (Blanc, Balmer, Landis, & Vingerhoets, 1999;Macellari et al, 1999). Figure 3 depicts that the gait period (walking speed) showed small variations as a function of the delay conditions.…”

“…Inspection of individual data ( Figure 2B) shows that agency judgments were as precise (and as elevated) as for the minimal delay of 16 ms in most participants, showing that variability does not account for dampening. Moreover, the sinusoidal pattern suggests that the cyclic nature of walking (Murray, 1967;Blanc Balmer, C., Landis, T., & Vingerhoets,, 1999) interfered with agency judgments. Gait agency may depend not only on delay, but also on gait cycle and gait speed.…”

Feeling in control of your footsteps: Conscious gait monitoring and the auditory consequences of footsteps

A fundamental aspect of the "I" of conscious experience is that the self is experienced as a single coherent representation of the entire, spatially situated body. The purpose of the present study was to investigate agency for the entire body. We provided participants with performance-related auditory cues and induced online sensorimotor conflicts in free walking conditions investigating the limits of human consciousness in moving agents. We show that the control of full-body locomotion and the building of a conscious experience of it are at least partially distinct brain processes. The comparable effects on agency using audio-motor and visuo-motor cues as found in the present and previous agency work may reflect common supramodal mechanisms in conscious action monitoring. Our data may help to refine the scientific criteria of selfhood and are of relevance for the investigation of neurological and psychiatric patients with disturbance of selfhood.

Objective. To determine the relationship between peak isometric muscle force and temporal characteristics of gait in individuals with sporadic inclusion body myositis (s-IBM).Methods. An observational study of 42 individuals with s-IBM (12 women; mean ؎ SD age 61.8 ؎ 7.3 years and mean ؎ SD disease duration 8.9 ؎ 4.3 years) was conducted at a federal hospital. Peak isometric force measurements for lower extremity (LE) muscle groups were obtained using quantitative muscle testing. Temporal characteristics of gait during habitual and fast walking conditions were measured using a portable gait analysis system. Results. All observed muscle force values were significantly lower than predicted values (P < 0.001). During habitual walking, the subjects' gait speed and cadence were <83% of normative literature values. During fast walking, total gait cycle time was 133% of normal, while gait speed and cadence were 58% and 78% of normative literature values, respectively. Scaled LE peak muscle forces showed significant moderate correlations with temporal gait variables. Weaker subjects had greater limitations in gait speed and cadence compared with stronger subjects (P < 0.05). Peak isometric force of the knee flexors and ankle plantar flexors was significantly correlated with most temporal features of habitual gait. Conclusion. Muscle weakness associated with s-IBM disease activity may contribute to diminished gait kinematics. Temporal features of gait were not substantially influenced by knee extensor weakness alone, considering the knee flexors and ankle plantar flexors played a compensatory role in maintaining the walking ability of individuals with s-IBM.
