简要总结
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.
详细描述
The primary objective of this study is to determine the feasibility and usability of the ABLE Exoskeleton for persons with SCI to perform skills for home and community environments during a training programme of up to 8 weeks. Results will be used to assess the potential of the device to be used in a home and community setting by persons with SCI, while providing meaningful insights to develop future features to improve its performance in those environments.
The secondary objectives are as follows:
- Assess the impact of ABLE Exoskeleton training on gait and function.
- Assess the effect of the ABLE Exoskeleton on the patients' perceived rate of exertion.
- Assess the impact of the ABLE Exoskeleton on the quality of life and general health of the participants.
- Assess the level of user satisfaction from participants and therapists of the ABLE Exoskeleton.
- Assess the psychosocial impact of the ABLE Exoskeleton for participants.
The primary hypothesis of this study is that the ABLE Exoskeleton is feasible to be used by persons with SCI to perform skills for home and community environments.
The secondary hypothesis is that the device will have a positive impact on the perceived rate of exertion, mobility and psychosocial health, and quality of life and general health of the study participants with SCI.

结局指标
主要结局
Tme to complete Home-Skills-Test and LoA for each task and ti [Usability/Feasibility]
时间窗: Up to 11 weeks
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.
Time and Level of Assistance (LoA) to don/doff the device [Usability/Feasibility]
时间窗: Up to 11 weeks
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.
LoA to complete skills for home and community environments [Usability/Feasibility]
时间窗: Up to 11 weeks
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).
Number of steps taken with the device [Usability/Feasibility]
时间窗: Up to 11 weeks
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.
Distance walked with the device [Usability/Feasibility]
时间窗: Up to 11 weeks
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.
Walking time with the device [Usability/Feasibility]
时间窗: Up to 11 weeks
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.
Standing time in the device [Usability/Feasibility]
时间窗: Up to 11 weeks
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.
