This study shows how concerted bodily movements and particularly intercorporeality play a central role in interaction, particularly in joint activities with people with late-stage dementia. Direct involvement of bodies in care situations makes intercorporeal collaboration the basic form for engaging with people with late-stage dementia. By detailed analysis of a videorecording of a joint activity involving a person with late-stage dementia as an example, we show that the process of concerted bodily movements includes not only an interactive bodywork but also a reconfiguration of the routine activities and actions in situ. Reconfigurations often require, and are the outcome of, particular practices for the systematic modification of the embodied conducts of the participants and their use of artifacts in the surrounding environment. These practices, that we highlight in our study, are (1) staging activities through organization and re-organization of body parts, as well as artifacts (rather than using verbal descriptions of activities); (2) decomposing (parsing) activities into smaller parts possible for the person with dementia to perform (rather than using verbal action descriptions); and (3) providing embodied directions and bodily demonstrations of actions (rather than using verbal directives). As a result, we point to these practices for their reflexive roles in the change of the use of modalities in interaction: from mainly using verbal language to the prominence of visual depiction and bodily demonstration as necessary methods to facilitate the participation of people with latestage dementia in joint activities
