Robotic Exoskeleton Assisted Gait Post Stroke

This study is looking at whether using a robotic exoskeleton device, called EksoGT™, can help people who have recently had a stroke improve their walking. It will compare the walking abilities of people who use the EksoGT™ as part of their rehabilitation to those who receive standard physical therapy. The study also aims to understand how walking with the EksoGT™ affects brain activity. You might be able to join if you are between 21 and 80 years old, had a stroke less than 4 weeks ago, and have weakness on one side of your body. The researchers will measure your functional independence and brain activity to see if the EksoGT™ helps. The study plans to enroll 75 participants, but its current status is unclear.

Study design
This interventional study plans to enroll 75 participants. It compares the EksoGT™ device to standard care and a group that only undergoes testing.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for changes in functional independence and brain activity at 10 weeks.

Eligibility criteria

Inclusion

Stroke survivors \< 4 weeks from most recent stroke.
Age: 21- 80 years
Unilateral hemiparesis
Medical clearance by the Medical Director
Be able to physically fit into the exoskeleton device.
Have joint range of motion within normal functional limits for ambulation.
Have sufficient strength to use the hemiwalker, cane or walker (etc. assistive device) while wearing the RE.
Patient cognitive status and ability to communicate in English must be at a level consistent with that required to participate in standard motor rehabilitation, e.g. can follow directions.
Adequate cognitive function to give informed consent, understand the training, instructions, use investigational devices and give adequate feedback.
No history of injury or pathology to the unaffected limb.
physically fit within the RE: Height below 60" or above 76" and weight above 220 lbs.

Exclusion

Any medical issue that precludes full weight bearing and ambulation (e.g. orthopedic injuries, pain, severe spasticity).
Skin issues that would prevent wearing the device.
Pre-existing condition that caused exercise intolerance.(Documented uncontrolled hypertension, coronary artery disease, cardiac arrhythmia, or congestive heart failure)
Hospitalization for heart attack, heart surgery or acute heart failure within 3 months of enrollment in study.
Severe cognitive or psychiatric problems as well as incontinence might be contraindications to start training with a RE.
History of severe cardiac disease such as myocardial infarction, congestive heart failure
Uncontrolled seizure disorder.
Uncontrolled spasticity or joint contracture that would interfere with walking in the RE and limits normal ROM during ambulation with assistive devices.
Neuromuscular or neurological pathologies (e.g., Parkinson's disease, spinal cord injury, or traumatic brain injury with evidence of motor weakness and multiple sclerosis) that will interfere with neuromuscular function, ambulation, or limit the range of motion of the lower limbs
Orthopedic pathologies or history that will interfere with ambulation or limit the ROM of the lower limbs (e.g., knee replacement, fixed contractures, inflammation)
Any metal implants that are NOT MRI-compatible
