Outcome Measures

Primary Outcomes (1)

  • Usability of the FRONTIER Soft Exoskeleton as Assessed by the System Usability Scale (SUS) Total Score

    Device usability will be measured using the 10-item System Usability Scale (SUS) following use of the FRONTIER soft exoskeleton prototype. Each item is rated on a 5-point Likert scale, and item scores are converted and combined to obtain a total score ranging from 0 to 100 points. Higher scores indicate greater perceived usability of the prototype. Device usability represents the primary feasibility-related outcome of the study and does not assess changes in participants' health status. SUS total scores will be reported separately for healthy volunteers and participants with chronic acquired brain injury.

    Day 1. Immediately after completion of the single testing session

Secondary Outcomes (5)

  • Difference in Mean Normalized Surface Electromyography (sEMG) Amplitude Between Robotic-Assisted and Unassisted Movements

    Day 1. During the single testing session

  • Mean Difference in Upper-Limb Range of Motion Between Robotic-Assisted and Unassisted Movements

    Day 1. During the single testing session

  • NASA Task Load Index (NASA-TLX) Overall Workload Score After Robotic-Assisted Testing

    Day 1. Immediately after completion of the robotic-assisted testing session

  • Mean Difference in Borg Category-Ratio 10 Fatigue Score Between Robotic-Assisted and Unassisted Movements

    Day 1. Immediately after each predefined movement performed with and without robotic assistance during the single testing session

  • Device-Related Adverse Events During the Single Testing Session

    Day 1. From device fitting through completion of the single testing session

Study Arms (1)

FRONTIER Soft Exoskeleton Testing

EXPERIMENTAL
Device: FRONTIER Soft Exoskeleton

Interventions

Each participant (both healthy volunteers and patients) will take part in one single testing session, structured as follows: 1. Unassisted condition: subjects will perform a set of standardized upper limb movements (shoulder, elbow, and hand) without robotic assistance. 2. Assisted condition (robot active): the same set of movements will be repeated with the support of the FRONTIER exoskeleton.
