Pilot study to assess the feasibility and initial efficacy of therapist-as-consultant, game-based CI therapy. Pre/post study design. Participant received a target of 30 hours game-based motor intervention, 100 hours constraint of the less affected upper extremity, and 5 hours therapist consultation (including completion of a behavioral contract at the first study visit).

• Can independently operate the gaming system (those with severe cognitive impairments can usually achieve this)
• Corrected vision of at least 20/70 as assessed by their ability to identify game objects on the monitor from 5 feet away

Exclusion Criteria:

• concurrent participation in other experimental upper extremity trials
• concurrent participation in other outpatient rehabilitation for their upper extremity
• Botox within the last 3 months (confound)
• near-normal motor function (9-hole Peg Test score above the 10th percentile of a normative sample)
• minimal nonuse (Motor Activity Log at baseline >2.5, Accelerometry > 60%)
• major medical issues that would interfere with study treatments or make intensive rehabilitation difficult to tolerate
