What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether people with spinal cord injuries can reach a high-intensity heart rate while walking in a robotic exoskeleton. Eleven participants completed five training sessions using the Ekso device. Researchers measured heart rate, walking speed, and endurance before and after training to see if this approach could improve fitness and mobility.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Ekso exoskeleton (wearable robotic device)
What this could lead to
If this approach works, it could point toward a way to improve walking ability and cardiovascular fitness in people with spinal cord injury during inpatient rehabilitation.
What could go wrong
This is a very small, early feasibility study with only 11 participants and no comparison group. Results may not apply to all people with spinal cord injury, and the device may not be suitable for everyone.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

11 people

The number who actually took part.

Started

Oct 2021

Finished

May 2023

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Able to achieve adequate fit within the exoskeleton * Diagnosis of CVA or motor incomplete SCI (AIS C or D) * Sufficient range of motion to attain normal, reciprocal gait pattern, and transition from normal sit to stand or stand to sit * Intact skin on all surfaces in contact with device and load-bearing surfaces * Weight \<220 pounds Exclusion Criteria: * Pregnancy * Spinal instability * Unhealed limb or pelvic fractures or any condition restricting weight-bearing in limbs * Diagnosis of other neurological injuries other than CVA or SCI * Uncontrolled spasticity (≥3 on Modified Ashworth Scale) * Colostomy * Decreased range of motion or contractures in legs (\>10° at hips, knees, or ankles) * Uncontrolled autonomic dysreflexia * Unresolved deep vein thrombosis * Inability to tolerate standing due to cardiovascular issues or orthostatic hypotension * Inability to follow 3 step commands * Severe comorbidities: active infections, heart, lung, or circulatory conditions * Pressure sores, impaired skin integrity * Use of mechanical ventilation for respiratory support
