What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a robot called BURT (Barrett Upper Extremity Robot) to aid arm movement recovery after a stroke. The study compares BURT therapy with regular therapy to determine if BURT improves strength and coordination more effectively. It also evaluates whether patients enjoy using BURT and find it helpful. Individuals who have experienced a stroke with weakened arm movement and are staying at Sunnyview Rehabilitation Hospital might be suitable candidates for this trial. As an unphased trial, this study provides a unique opportunity to explore innovative rehabilitation technology.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the Barrett Upper Extremity Robot (BURT) is safe for stroke rehabilitation?

Research has shown that the BURT robotic arm is safe for arm therapy. Studies have found that patients comfortably handle sessions lasting 30 to 60 minutes. The FDA has approved the BURT device, confirming it meets safety standards for therapy use. Patients using BURT have experienced few negative side effects, indicating it is well-tolerated. Overall, the safety evidence supports using BURT to improve arm strength and movement in stroke recovery. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about BURT therapy for stroke recovery because it introduces a novel approach to neuroeducation by using advanced robotics to assist with upper extremity rehabilitation. Unlike conventional occupational therapy, which focuses on traditional exercises and might include tools like electrical stimulation and arm bikes, BURT therapy leverages robotic technology to provide precise and consistent movement assistance. This innovative method aims to enhance the effectiveness of therapy by offering tailored support based on each patient's needs, potentially accelerating recovery and improving outcomes.

What evidence suggests that BURT therapy is effective for stroke rehabilitation?

Research has shown that the BURT robotic arm can enhance arm and hand function in stroke patients. In this trial, some participants will receive BURT therapy, which studies have found leads to greater improvement in strength, fine motor skills, and daily activities compared to regular therapy. One study noted that BURT therapy improved arm recovery by enhancing movement. Another study highlighted that BURT therapy allows for more practice, which helps build strength and coordination. Meanwhile, other participants in this trial will receive conventional upper extremity neuroeducation. Overall, these findings suggest that BURT therapy effectively improves arm and hand movement after a stroke. ^{1 5 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• BURT
• Occupational Therapy

Trial Overview The study tests if using the Barrett Upper Extremity Robot (BURT) during rehab after a stroke improves arm strength and function more than standard therapy. BURT offers high-repetition exercises through video games that adapt to patient fatigue. Participants will either receive this new robotic therapy or conventional occupational therapy.

How Is the Trial Designed?

Group I: BURT Upper Extremity Experimental Treatment 2 Interventions

As part of routine therapy, 74 patients will receive up to 5 sessions per week of BURT UE therapy in place of conventional neuro re-education. Patients in this arm of the study will receive any conventional therapy during the remainder of their treatment sessions. When using BURT, therapists will track the activity, level of assistance and time provided in a tracking sheet, as well as document any adverse events that may occur.

Group II: Conventional Upper Extremity Neuroeducation Active Control 1 Intervention

74 patients will receive the standard occupational therapy sessions that they would normally receive during their IRF stay. UE neuroeducation sessions are typically focused on improving strength and mobility of the upper arm. Clinicians will not be given instructions on how to run their sessions, however they will not be allowed to use BURT. Other devices that would normally be used during neuro-educational sessions (including X-cite, electrical stimulation and RT-300) will be allowed for use in this group. The therapists will track the activity, level of assistance and time provided in a tracking sheet, as well as document any adverse events that may occur

In a study involving 10 sub-acute stroke patients, the Reo Therapy System, a robotic device for upper extremity rehabilitation, was well-accepted and resulted in high patient satisfaction after 15 training sessions.

Significant improvements in arm impairment and functionality were observed, as measured by the Fugl-Meyer test and the Manual Function Test, indicating the efficacy of the robotic therapy in enhancing rehabilitation outcomes.

In a one-year study involving 50 post-stroke patients, robotic training combined with occupational therapy significantly improved upper limb function and independence-related quality of life compared to traditional occupational therapy alone.

While robotic-assisted training showed large treatment effects on upper limb movement and daily living activities, it did not fully achieve complete functional independence or significantly enhance overall quality of life.

In a study involving 30 tetraplegic spinal cord injury patients, combined upper limb robotic therapy (RT) showed beneficial effects on upper limb motor function, particularly in specific tasks like bathing and grooming, after 5 weeks of treatment.

While both robotic therapy and conventional occupational therapy (OT) improved upper limb function, the RT group had significant enhancements in certain strength and functional measures, indicating that robotic therapy can be an effective alternative to traditional methods.

Endovascular treatment (ET) for patients with basilar artery occlusion (BAO) significantly improves functional outcomes at 90 days compared to standard medical treatment (SMT), with 45.1% of ET patients achieving a good functional outcome versus 29.6% in the SMT group.

While ET reduces mortality at 90 days (35.6% vs 45.4% for SMT), it also increases the risk of symptomatic intracranial hemorrhage (sICH) (5.4% vs 0.5%), indicating a trade-off between improved outcomes and safety risks.

Robot-assisted upper limb therapy (RT-UL) remains a sustainable and regularly used intervention for stroke survivors in rehabilitation, with consistent engagement in therapy sessions over a two-year period.

Despite a reduction in the total number of RT-UL sessions due to fewer stroke admissions, the average number of sessions per patient and session duration remained stable, indicating effective integration into routine therapy practices.

The inter-rater reliability of the PEDro scale, used to assess the quality of randomized controlled trials in occupational therapy, was found to be 'good to excellent' both before and after revising the rating guidelines, indicating its effectiveness as a reliable assessment tool.

Revising the guidelines improved the reliability of certain items on the PEDro scale, particularly for 'less than 15% dropout' and 'point measures and variability', while the item 'groups similar at baseline' still showed moderate reliability, suggesting areas for further improvement.

A study involving 44 stroke patients found that both robot-assisted therapy (RT) and conventional therapy (CT) significantly reduced upper extremity spasticity and improved muscle strength and function after 2 weeks of treatment.

The results indicated that RT is as effective as CT in managing spasticity, suggesting it could be a valuable tool for providing consistent and precise rehabilitation exercises for stroke patients.
