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.
