We investigated motivational regulation involving adjustment of recovery goals in post‐stroke rehabilitation via standard in‐clinic physiotherapy and in‐home telerehabilitation (TR). We used a secondary dataset collected at 11 US sites as part of a clinical trial using video games and game control pads designed to induce certain arm movements required for recovery (n = 124; Mage = 61.44, SD = 13.30). Participants were randomly assigned to either the TR or in‐clinic condition and underwent 36 therapy sessions, reporting on their activity‐inherent enjoyment for 6–8 weeks. Compared with the in‐clinic patients and TR patients with high game performance, TR patients with lower game performance reported lower activity‐inherent enjoyment, which is an important motivational resource for successful recovery. The results suggest that these differences occur because TR patients become discouraged by low game score feedback, which may have signaled a poor prospect for recovery. However, the results also suggest that low game performers who successfully adjusted their recovery goals were resilient to the impact of low game score feedback on their motivational resources and satisfaction with therapy. The findings suggest that goal adjustment may be particularly beneficial when patients are discouraged by feedback indicating suboptimal recovery prospects.
