Brief Summary

The loss of the ability to walk and the associated restriction of mobility presents a major challenge to people with spinal cord injury in an everyday environment designed for pedestrians. Exoskeletal technology has the potential to help people with impaired leg function to regain ambulation and thus improve their independence. This technology is not completely new, but due to their high access price (\~120k€/unit), high size and weight (\~25 kg), and need for trained physiotherapist supervision, commercially available exoskeletons are only found in large hospitals and only in very few cases get into patients' homes. The company ABLE Human Motion S.L. (Barcelona, Spain) has developed a novel exoskeleton to overcome these disadvantages, which is more compact, lighter and easier to use. The primary objective of this study is to determine the feasibility and usability of the ABLE Exoskeleton for persons with SCI to perform skills in home and community environments.

Outcome Measures

Primary Outcomes (7)

  • Time and Level of Assistance (LoA) to don/doff the device [Usability/Feasibility]

    Level of Assistance (LoA) and time taken to don/doff the device will be measured in every session. LoA will be measured using a 6-item scale, from Total assistance to Independence. Different assistance levels are defined taking into account the degree of participation of the patient and the therapist in performing the activity.

    Up to 11 weeks

  • LoA to complete skills for home and community environments [Usability/Feasibility]

    The participant will attempt a set of skills for home and community environments every session to assess the device's usability. The therapist will record the LoA required to complete each task during every session. The best LoA-Score of all 15 tasks within 3 consecutive training sessions will be recorded and analysed (sessions 2-4, sessions 5-7, sessions 8-10, sessions 11-14, sessions 15-17, sessions 18-20).

    Up to 11 weeks

  • Tme to complete Home-Skills-Test and LoA for each task and ti [Usability/Feasibility]

    A Home-skills-test will be performed by all participants and will consist of 10 of the skills for home and community environments, set out in a sequence to simulate daily life situations. The test will be attempted twice with a 5 min break in between, the best result will be documented. To assure safety, participants will attempt the test with assistance from the therapist as required. For all skills of the Home-skills-test, the LoA to complete each task and the time to complete the test will be documented.

    Up to 11 weeks

  • Number of steps taken with the device [Usability/Feasibility]

    The ABLE Exoskeleton device will record the number of steps, walking time, standing time, and walking distance every session. This information will allow insight into the proportion of time spent training per session.

    Up to 11 weeks

  • Distance walked with the device [Usability/Feasibility]

    The ABLE Exoskeleton device will record the number of steps, walking time, standing time, and walking distance every session. This information will allow insight into the proportion of time spent training per session.

    Up to 11 weeks

  • Walking time with the device [Usability/Feasibility]

    The ABLE Exoskeleton device will record the number of steps, walking time, standing time, and walking distance every session. This information will allow insight into the proportion of time spent training per session.

    Up to 11 weeks

  • Standing time in the device [Usability/Feasibility]

    The ABLE Exoskeleton device will record the number of steps, walking time, standing time, and walking distance every session. This information will allow insight into the proportion of time spent training per session.

    Up to 11 weeks

Secondary Outcomes (10)

  • BORG Scale [Perceived rate of exertion]

    Up to 11 weeks

  • 6-Minute Walk Test (6 MWT) [Gait and function]

    Up to 11 weeks

  • 10-Meter Walking Test (10 MWT) [Gait and function]

    Up to 11 weeks

  • Timed up and go test (TUG) [Gait and function]

    Up to 11 weeks

    Up to 11 weeks

  • +5 more secondary outcomes
