Study summary

This pilot feasibility study will evaluate a wearable soft elbow exosuit and a haptic forearm bracelet for upper-limb neurorehabilitation in people with stroke and Parkinson's disease. The soft elbow exosuit is designed to assist elbow flexion and extension during functional motor tasks while preserving comfort and natural movement, with the possibility of deploying vibrotactile stimuli. The haptic bracelet provides tactile and vibrotactile feedback to support sensorimotor engagement, movement guidance, and proprioceptive awareness.

The study will assess the feasibility, usability, comfort, acceptability, safety, and preliminary clinical impact of these devices in a real neurorehabilitation setting. Participants with stroke will be tested using either the soft elbow exosuit or the haptic bracelet, depending on their stage of recovery and residual upper-limb motor function. Participants with Parkinson's disease will be tested with the soft elbow exosuit combined with integrated haptic feedback, with specific interest in motor performance and tremor modulation.

Participants will undergo baseline clinical and functional assessment, followed by supervised experimental sessions involving upper-limb functional tasks such as reaching, grasping, releasing, pick-and-place exercises, elbow flexion-extension, forearm pronation-supination, and fine or gross motor activities. Sessions may be performed with and without device assistance. Non-invasive sensors, including inertial measurement units and electromyography, will be used to collect movement and muscle activity data. User experience will be assessed using standardized questionnaires addressing usability, satisfaction, perceived benefit, comfort, and musculoskeletal discomfort.

The study is intended to generate preliminary evidence on the safe and acceptable use of wearable soft robotic and haptic technologies in neurological rehabilitation and to inform the design of future larger clinical trials.

Read the detailed description

This clinical investigation is designed to evaluate the use of wearable assistive and haptic technologies for upper-limb rehabilitation in neurological populations. The study focuses on two non-invasive devices: a soft wearable elbow exosuit intended to assist elbow flexion-extension, and a wearable haptic forearm bracelet intended to provide tactile and vibrotactile feedback during upper-limb motor tasks. The technologies are intended to support motor practice, sensorimotor engagement, and task-oriented rehabilitation while maintaining comfort and allowing natural movement.

The rationale for the study is based on the persistent need for scalable, acceptable, and clinically usable technologies that can enhance upper-limb rehabilitation after stroke and in Parkinson's disease. Upper-limb motor impairment is common in both conditions and may limit independence, functional performance, and quality of life. Although intensive, repetitive, and task-oriented rehabilitation is associated with better outcomes, its delivery in routine clinical practice may be constrained by time, staffing, and physical workload. Wearable soft robotic and haptic systems may help address these limitations by providing movement assistance, sensory feedback, and objective measurement during supervised rehabilitation activities.

Participants will complete an initial clinical and functional assessment followed by supervised experimental sessions in which the devices will be used during standardized upper-limb tasks. These activities may include reaching, grasping, releasing, pick-and-place movements, elbow flexion-extension, forearm pronation-supination, and other functional exercises selected according to the participant's clinical condition and motor ability. Tasks will be performed in seated position under the supervision of qualified clinical staff, with rest periods provided as needed. Device-assisted and non-assisted conditions may be compared to explore feasibility, user experience, and preliminary effects on movement performance.

In participants with stroke, the soft elbow exosuit will be evaluated primarily as an assistive device for individuals requiring support during elbow movement, whereas the haptic bracelet will be evaluated in participants with sufficient residual voluntary motor control to interact with sensory feedback during active rehabilitation tasks. In participants with Parkinson's disease, the combined use of elbow assistance and haptic feedback will be explored, with particular attention to upper-limb motor performance and tremor-related movement fluctuations during functional tasks.

The study will collect both objective and subjective data. Objective assessments will include non-invasive biomechanical and physiological measures, such as kinematic data from inertial sensors and muscle activity from surface electromyography, recorded during standardized motor tasks. These data will be used to explore changes in movement quality, joint motion, smoothness, compensatory strategies, muscle activation patterns, and tremor-related features where applicable. Subjective assessments will address usability, comfort, perceived benefit, satisfaction, technology acceptance, and possible musculoskeletal discomfort associated with device use.

The primary purpose of the study is to determine whether these wearable technologies can be feasibly, safely, and acceptably integrated into supervised neurorehabilitation sessions. The study will also generate preliminary information on user experience, device performance, and short-term motor effects. The findings are expected to inform refinements of the devices, optimize future rehabilitation protocols, and support the design of larger controlled clinical studies evaluating wearable soft robotic and haptic technologies for upper-limb neurorehabilitation.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

MMSE and MoCA

Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. System Usability Scale score

    The usability of the wearable upper-limb rehabilitation devices will be assessed using the System Usability Scale. The scale provides a total score ranging from 0 to 100, with higher scores indicating better perceived usability.

    Time frame: After completion of the final device-assisted experimental session, up to 4 weeks after baseline

  2. Quest 2.0

    Participant satisfaction with the wearable device intervention will be assessed using the Quebec User Evaluation of Satisfaction with Assistive Technology 2.0 (QUEST 2.0). The questionnaire evaluates satisfaction (score from 1 to 5) with device characteristics such as comfort, ease of use, effectiveness, and overall acceptability. Higher scores indicate greater satisfaction.

    Time frame: After completion of the final device-assisted experimental session, up to 4 weeks after baseline

  3. Number of device-related adverse events and technical issues

    Safety and device performance will be assessed by recording the number, type, and severity of device-related adverse events, discomfort episodes, technical malfunctions, usability problems, or session interruptions occurring during use of the wearable upper-limb rehabilitation devices. The evaluation of this specific outcome will be based on counting issues (0 to N; higher = worse).

    Time frame: During each experimental session, up to 4 weeks after baseline

  4. Protocol completion rate

    Feasibility will be assessed as the proportion of enrolled participants who complete all protocol-defined experimental sessions and assessments. The scoring will be calculated as the proportion (%) of the completed protocol-defined sessions (0-100%). A higher completion rate will indicate greater feasibility of the study procedures and device use in the clinical rehabilitation setting.

    Time frame: During each experimental session, up to 4 weeks after baseline

  5. Musculoskeletal discomfort assessed by the Extended Nordic Musculoskeletal Questionnaire

    Musculoskeletal discomfort potentially associated with device use will be assessed using the Extended Nordic Musculoskeletal Questionnaire NMQ-E). The questionnaire will be used to identify discomfort, pain, or perceived physical burden in body regions potentially affected by the wearable devices. The outcome evaluates the number of body regions with new/worsened discomfort (0-9; higher = worse)

    Time frame: Before and after device-assisted experimental sessions, up to 4 weeks after baseline

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.
