Study summary

The loss of lower limb strength that occurs after an Acquired Brain Injury (ABI) limits the patient's autonomy in participating in activities of daily living, including gait performance. In the sub-acute phase, it is difficult to implement a strengthening program, as weakness prevents exercise being performed with the recommended parameters. This limit can be exceeded by using specific robotic devices, which allow the effort provided to be adapted according to the patient's capacities. In addition, motivation can be improved by the use of feedback or incentive games. The aim of this pilot study is to obtain data on the effect of lower limb strength training with a seated robotic device in subacute ABI patients for a future larger randomised study. In addition, it aims to evaluate the recruitment rate, applicability, resources for implementation and patient tolerance to the training program.

Study arms

  • Experimental
    intervention group

    group focus on lower limb strength training with a seated robotic device

    Device: Group of strength training

  • Active comparator
    control group

    physiotherapy group as usual, not focused on strength training

    Other: Group of physiotherapy not focus on strength training

Interventions

  • DeviceGroup of strength training

    2x a week during 5 weeks, strengthening of weak muscles with the intensity recommended in the literature, i.e. 3-4x15 repetition at an intensity of 50 to 80% of the maximum force combined with serious games to stimulate patient involvement in strength training

  • OtherGroup of physiotherapy not focus on strength training

    2x a week during 5 weeks, active physical therapy treatment based on movement

What researchers measure

Primary outcomes

  1. change from study inclusion to end of intervention at 5 weeks in strength of knee extensor's

    measure with a manuel dynamometer, in newton

    Time frame: Study inclusion to end of intervention at 5 weeks

Secondary outcomes

  1. change from study inclusion to end of intervention at 5 weeks in Motricity index legs

    clinical manuel strength test, seating on a chair. From 0 to 33, 33 is normal strength.

    Time frame: Study inclusion to end of intervention at 5 weeks

  2. change from study inclusion to end of intervention at 5 weeks in timed up and go

    Mobility test: standing from a chair, walking 3 meters, turn around, returning and seat. in seconds

    Time frame: Study inclusion to end of intervention at 5 weeks

  3. change from study inclusion to end of intervention at 5 weeks in 10 meters walk test

    measure of mean gait speed on 10 meters, at comfortable and maximum gait speed. In meters/second.

    Time frame: Study inclusion to end of intervention at 5 weeks

  4. change from study inclusion to end of intervention at 5 weeks in Ashworth Scale (spasticity)

    measure of the resistance of a muscle to passive stretch according to REsistance to PASsive movement protocol. From 0 to 4, 4 is high spasticity.

    Time frame: Study inclusion to end of intervention at 5 weeks

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 May 3, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
