Exclusion criteria

Exclusion Criteria:

  1. The range of motion of the joints is severely limited and the walking action is limited
  2. Spinal fractures are not completely healed, the clinical situation is unstable; if not fully confirmed,please go department of orthopedics or other clinical departments for diagnosing
  3. Skin injury or infection of the lower extremities or the part of wearing robot
  4. Unstable angina, severe arrhythmia and other heart diseases
  5. Severe
  6. Unilateral neglect
  7. Severe cognitive or visual impairment
  8. Other or complications that may affect walking training
  9. Pregnant or lactating women
  10. The investigators find that patients with poor compliance, unable to complete the study in accordance with the requirements
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    AiLegs/AiWalker

    use of lower extremity rehabilitation training robot assisted walking (including AiLegs, AiWalker)

    Device: AiLegs, AiWalker and HKAFO

  • Active comparator
    HKAFO/RGO

    use hip and knee ankle foot orthosis (HKAFO) assisted walking

    Device: AiLegs, AiWalker and HKAFO

Interventions

  • DeviceAiLegs, AiWalker and HKAFO

    5 days. Using their own control method, each morning using AiLegs, AiWalker AiWalker and HKAFO for 6 minutes walk test, three kinds of appliance between at least 30 minutes to determine heart rate, blood pressure and breathing back to quiet level. Repeat the same procedure in the afternoon ,the order is also random. Each participant will complete 10 groups of lower limb exoskeleton rehabilitation Training robot (including AiLegs, AiWalker two models) and HKAFO 6 minutes walking test

What researchers measure

Primary outcomes

  1. Walking efficiency

    6 minute walk distance,measured by meters

    Time frame: 6 minute

  2. Walking efficiency

    average heart increasing rate,measured by times/min

    Time frame: 6 minute

Secondary outcomes

  1. Cardiovascular response

    heart rate during and after 6 minute walk test

    Time frame: during 6 minute walk test and right before the 6MWT

  2. efficiency of put on or take off the Ailegs/Aiwalker/HKAFO

    to measure the time of putting on or taking off the Ailegs/Aiwalker/HKAFO before or after 6 min walk test

    Time frame: immediately before beginning (pre-) and immediately after finishing (post-) each of 6 minute walk test

  3. RPE questionaire

    the RPE is recorded after the 6 min walk test

    Time frame: after 6 minute walk test

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2017 to primary completion in Jan 2018, 6 months.

Of 49 industry-sponsored interventional studies with no phase under Spinal Cord Injuries, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 28. This study's 6 months is below that.

Counting every sponsor, half of 839 studies reached it within 36 months; a quarter within 17 and three quarters within 64.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 30, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
