text: We argue that participants’ perceived bodily changes affected 
  their self-efﬁcacy for being physically active. Self-efﬁcacy involves 
  an individual’s perception of exerting control over his or her 
  own actions (37) and has been extensively reported to be 
  pertinent to PA engagement in pwMS (38, 39). However, self- 
  efﬁcacy is theoretically described according to social cognitive 
  theory (38). Our ﬁndings highlight how experiencing, expressing 
  and socially interacting through the body (embodied experiences) 
  shape individuals’ self-efﬁcacy and suggest a crucial role of bodily 
  perceptions in constituting self-efﬁcacy for PA.
