Brief Summary:
The overall objective of the proposed study is to carry out usability and design-evaluation assessments of the BURT robotic device for delivering long-term intervention in stroke survivors. The BURT is an upper extremity robotic device that enables the user to see and feel engaging games that encourage intensive therapy. The investigators intend to recruit up to 10 stroke survivors over the course of the study. Participants will train their arm with the BURT for 18 sessions over approximately 6 weeks then participate in a question/answer formatted discussion with research staff to discuss the usability of the device. The investigators will also assess participant's arm function at baseline and after the training sessions.

Arm Intervention/treatment
Experimental: Arm motor function retraining with BURT
All participants will receive 1 hour sessions, 2-3x/week for 6 weeks (total 18 sessions). Sessions will be organized with 30 minutes of robotic-assisted training and 30 minutes of hands-on training with a research therapist to work on the baseline goals of the subject. Hands-on training will be done with routinely employed techniques in therapy to transfer the skills gained with the robotic device in everyday life activities.
Device: Arm motor function retraining with BURT
Intervention will be focused on patients impairments to assess the feasibility of the BURT device to carry-on long interventions

Primary Outcome Measures :
  1. Fugl-Meyer Upper Extremity Scale [ Time Frame: Change from baseline scores at 6 weeks ]
    Assessment of upper extremity impairments. Individual items of the scale are summed for a total score ranking from 0 to 66. Higher scores indicate better outcomes.

Secondary Outcome Measures :
  1. Goal Attainment Scale [ Time Frame: Change from baseline scores at 6 weeks ]
    Standardized measure of goals selection and scaling to calculate the extend to which the participant's goals are met. Positive scores indicates goals are better than expected, score of 0 indicates goals are met and negative scores indicates goals aren't met.

Other Outcome Measures:
  1. Wolf Motor Function Test [ Time Frame: Change from baseline scores at 6 weeks ]
    Assessment of upper extremity function

  2. Motor Activity Log [ Time Frame: Change from baseline scores at 6 weeks ]
    Use of upper extremity in daily life

  3. Modified Ashworth Scale [ Time Frame: Change from baseline scores at 6 weeks ]
    Assessment of muscle tone for upper extremity muscles. Score rank from 0 (no tone) to 4 (no movement possible). Lower scores indicates a better outcome.

  4. Articulations range of motion [ Time Frame: Change from baseline scores at 6 weeks ]
    Assessment of arm range of motion with goniometry. Results are reported in degrees and higher ranges include better outcomes.

  5. Manual muscle testing scale [ Time Frame: Change from baseline scores at 6 weeks ]
    Assessment of arm muscle strength using the manual muscle testing scale ranking from 0 (no contraction) to 5 (maximal strength). Higher scores indicate better outcomes.
