The purpose of this single-subject, concurrent mixed methods study is to investigate the relationship between the effect of the CIMT protocol on gait and mobility and participants` and caregivers` expectations and perceptions regarding the treatment. The goal of the quantitative strand is to assess changes in quality of movement and functional use of the paretic lower limb after the treatment and investigate the participants` expectations in regards the intervention using the Participant Opinion Survey (POS). The qualitative strand (participant interviews) will determine perspectives of caregiver and participant perspectives regarding protocol acceptability. Both quantitative and qualitative data will be collected and analyzed concurrently, through triangulation and complementarity rationales; both data will be equally prioritized.
