The primary objective of the study is to validate the safety and clinical performance of the ABLE Exoskeleton device in people with acquired brain injury during a 10-session gait training program in a clinical setting.
The secondary objective of the study focuses on obtaining preliminary data on the potential clinical and psychosocial benefits of the product.
This is a pre-post, multicenter, quasi-experimental study with an estimated duration of 17 weeks. The study will be conducted at the Centro Europeo de Neurociencias (CEN), Cefine NeurologÃa (CEFINE), and Fundación Step by Step Foundation, where a minimum of 15 participants (5 per center) are expected to be recruited within a period of 8 weeks.
After obtaining informed consent, through the Patient Information Sheet and the Informed Consent Form, the selection of the participants will be carried out to determine their inclusion in the study. Subjects who do not meet all the inclusion and exclusion criteria during the screening visit will be excluded from the study. At the latest, one week after the screening visit, the participants will undergo a baseline assessment without the medical device.
Participants will undergo a 10-session training program with the ABLE Exoskeleton device for a maximum duration of 6 weeks. Sessions will be conducted 2 times per week. Each session will last approximately 60 minutes. During the training period, session data will be taken to assess the safety and clinical performance of the device. At the latest, one week after the last training session, a post-training assessment will be performed. Finally, two weeks after the last training session, a follow-up assessment will be made to the participants via a telephone call to review any adverse events (AE) reported between the end of the training and the follow-up.

In each gait training session, the time spent upright (in minutes) and the time spent walking (in minutes) with the device will be automatically measured and registered by the device |
| Up to 6 weeks |
| Number of therapists assisting the session | In each gait training session, the number of therapists assisting will be recorded | Up to 6 weeks |
| Level of Assistance (LoA) during training | Four therapy activity tasks will be attempted every session by the participant. The therapist will record the level of assistance required to complete each task during the session, using a 6-item scale, from Total assistance to Independence, with Independence being the best outcome possible. The tasks are the following: sit-to-stand, walk 10 meters, turn 180 degrees, and stand-to-sit. | Up to 6 weeks |
The patient's walking ability is evaluated with the Functional Ambulation Category (FAC) scale. It has 6 categories, from 0 (patient who is not able to walk) to 5 (independent patient who does not need any help to walk) |
| At baseline(day 0) and post-training (up to 7 weeks) |
| 10-Meter Walking Test (10MWT) | The 10-Meter Walking Test (10MWT) test measures the time a person needs to walk 10 meters. This test will be performed in the pre-post evaluations without the device to assess the change in the walking function after the training. | At baseline(day 0) and post-training (up to 7 weeks) |
| 6-Minute Walk Test (6MWT) | The 6-Minute Walk Test (6MWT) measures the distance a person can walk in 6 minutes. This test will be assessed at baseline and at the end of the gait training program without the device to assess the change in the walking function after the training | At baseline (day 0) and post-training (up to 7 weeks) |
| Timed Up and Go (TUG) | The Timed Up-and-Go Test (TUG) measures the time it takes a person to get up from a chair, walk 3 meters, turn around, and sit down again. This test will be performed in the pre-post evaluations without the device to assess the change in the walking function after the training. | At baseline (day 0) and post-training (up to 7 weeks) |
| Trunk Impairment Scale (TIS) | The Trunk Impairment Scale (TIS) measures the motor impairment of the trunk through the evaluation of static and dynamic sitting balance as well as coordination of trunk movement. The total score ranges from 0 (minimal performance) to 23 (perfect performance). | At baseline (day 0) and post-training (up to 7 weeks) |
| Berg Balance Scale (BBS) | The Berg Balance Scale (BBS) is used to assess the patient's ability to safely stabilize while performing certain tasks. It consists of a list of 14 items. Each item is evaluated through an ordinal scale ranging from 0 (lowest level of functionality) to 4 (highest level of functionality). | At baseline and post-training (up to 7 weeks) |
| Modified Ashworth Scale (MAS) | The Modified Ashworth Scale (MAS) measures spasticity in patients with lesions to the central nervous system. The scale assigns a grade of spasticity from 0 (no increase in muscle tone) to 4 (affected part rigid in flexion or extension). | At selection, baseline and post-training (up to 7 weeks) |
| Location and level of pain | The location and level of pain using the numeric rating scale (NRS) will be assessed. Each value is scored on a 0 to 10 scale, where 0 represents no pain and 10 represents the worst pain imaginable. | From baseline to post-training (up to 7 weeks) |
| Borg Rating of Perceived Exertion | The Borg Rating of Perceived Exertion (RPE) scale is used to measure a person's perception of their effort and exertion, breathlessness, and fatigue during physical activity. Scores range from 6 (no exertion at all) to 20 (maximal exertion). | From baseline to post-training (up to 7 weeks) |
| Functional Independence Measure (FIM) | The Functional Independence Scale (FIM) is a widely used instrument to assess the patient's outcomes and progress in rehabilitation programs. It is an indicator of disability, which measures how much assistance the patient needs to perform activities of daily living . It includes 18 activities that are measured on a 7-level scale, with 1 being indicative of total assistance and 7 of complete independence. | At baseline and post-training (up to 7 weeks) |
| Level of motivation | Participants' perceptions on the level of motivation generated by the program with the ABLE Exoskeleton will be evaluated by the completion of a self-report questionnaire using a 7-point Likert scale. This questionnaire has been designed by the researchers. | At post-training (up to 7 weeks from baseline) |
| Self-perceived impact on general health status | Participants' perceptions of the impact on their general health will be evaluated by the completion of a self-report questionnaire on the perceived impact on general health. This questionnaire has been designed by the researchers and intends to identify to what extent participants feel that the ABLE Exoskeleton contributed to a change in their health. The questionnaire covers 7 categories (cardiovascular system, musculoskeletal pain, neuropathic pain, bladder and bowel, spasticity, and sleep quality) using a 7-point Likert scale to assess the change. | At post-training (up to 7 weeks) |
| Psychosocial Impact of Assistive Devices Scale (PIADS) score | The Psychosocial Impact of Assistive Devices Scale (PIADS) is a 26-item, self-reported questionnaire that provides a measure of user perception and other psychological factors associated with assistive technology devices. Scores range from -78 (maximum negative impact) to +78 (maximum positive impact). It will be used to assess the effects of the ABLE Exoskeleton on functional independence, well-being, and quality of life of participants after the training program experience | At post-training (up to 7 weeks) |
| Quebec User Evaluation of Satisfaction with assistive Technology (QUEST 2.0) score | The Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) is a 12-item outcome measure that assesses user satisfaction with two components (Device and Services) using a 5-point scale ranging from 1 (not satisfied) to 5 (very satisfied). Only the 8 items referred to the device will be evaluated from participants and the whole 12 items from the therapists to measure user satisfaction with the ABLE Exoskeleton after the training program experience | At post-training (up to 7 weeks) |
