Please assess the completion status of the following clinical trial:

Trial Title: Ankle Robotics Training After Stroke

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: None
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 3.0

Eligibility Criteria:
Inclusion Criteria:~* Ischemic or hemorrhagic stroke \>6 months prior in men or women aged between 18-80 years.~* Clear indications of hemiparetic gait by clinical observation.~* Completed all conventional physical therapy.~* Ability to walk on a treadmill with handrail support.~Exclusion Criteria:~* Cardiac history of (a) unstable angina, (b) recent (less than 3 months) myocardial infarction, congestive heart failure (NYHA category II); (c) hemodynamically significant valvular dysfunction.~* Major clinical depression: CESD score \> 16 and judgment of clinical depression~* Medical History: (a) recent hospitalization (less than 3 months) for severe medical disease, (b) symptomatic peripheral arterial occlusive disease, (c) orthopedic or chronic pain conditions that significantly alter gait function, (d) pulmonary or renal failure (e) active cancer~* History of non-stroke neuromuscular disorder restricting gait.~* Aphasia or cognitive functioning that confounds participation, defined as unable to follow 2 step commands. The Mini Mental State Exam will be administered with a cut-off of less than 23 (less than 17 if education level at or below 8th grade), or judgment of the medical officer.~* Hypertension that is a contraindication for a bout of treadmill training (greater than 160/100 on two assessments).~* Self-report of pregnancy

Study Arms:
- Arm 1 (Type: EXPERIMENTAL): Seated robot training group. Participants at least 6 mos. post-stroke will use the ankle robot in a seated visuo-motor training paradigm. They will train on the robot 3x weekly for 6-weeks (18 sessions) by playing videogames with the paretic ankle. They will be evaluated on outcomes at baseline, post-6 weeks training, and again after a 6-week retention period with no training.
- Arm 2 (Type: EXPERIMENTAL): Treadmill training with ankle robot group. Participants at least 6 mos. post-stroke will wear the ankle robot during treadmill locomotor training. They will walk on a treadmill with the ankle robot adjusted to promote paretic ankle engagement during 3 x weekly training sessions over 6 weeks (18 sessions). They will be evaluated on outcomes at baseline, post-6 weeks training, and again after a 6-week retention period with no training.
- Arm 3 (Type: ACTIVE_COMPARATOR): Treadmill only group. This group will consist of participants at least 6 mos. post-stroke who engage in treadmill training 3x weekly for 6 weeks without robotic support. They will be volunteers from another treadmill training study and evaluated on outcomes at baseline and post-6 weeks training. They will not receive retention testing at 12 weeks because they will be continuing with regular treadmill training beyond the 6-week period.

Based on this trial design, predict the completion outcome and termination type (if applicable).
