What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.

Summary

This trial tests whether adding a robotic leg-training device (ZEPU-AI5) to standard rehab can safely improve walking, strength, and balance in adults aged 18–60 with lower-limb problems from stroke, incomplete spinal cord injury, or orthopedic surgery. Participants will receive either robot-assisted training plus usual rehab, or usual rehab alone, three times a week for 12 weeks. The study tracks safety issues like falls or joint pain, and measures improvements in walking distance and muscle strength.

What this could mean

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

Active substance
a robotic lower-limb strength training and evaluation device called ZEPU-AI5
What this could lead to
If it works, robot-assisted training could become a standard addition to rehab, helping people regain walking ability faster and more safely.
What could go wrong
This is a small early-stage trial with only 36 participants, so results may not apply to everyone. The device could cause falls, skin sores, or joint pain.

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

Inclusion Criteria: * Lower-limb motor dysfunction due to one of the following: (a) stroke (onset 2-24 months), (b) incomplete spinal cord injury (neurological level T12 or below, ASIA Impairment Scale C or D), or (c) orthopedic surgery (e.g., knee/hip replacement) with persistent gait impairment more than 3 months post-surgery * Age greater than 18 years and up to 60 years * Medically stable and able to provide informed consent * Able to meet device anthropometric criteria for use of the ZEPU-AI5 system Exclusion Criteria: * Complete spinal cord injury with inability to bear any weight * Severe cognitive impairment (Mini-Mental State Examination score less than 24) preventing safe participation * Severe spasticity of the lower limbs (Modified Ashworth Scale greater than 3) * Unstable fractures, severe hip/knee contractures (greater than 30 degrees fixed flexion), or severe osteoarthritis requiring imminent surgery * Uncontrolled cardiac arrhythmia, pacemaker incompatibility, or any implanted electronic device incompatible with the robot's sensors * Pregnancy
