Wearable robot arm and smart bracelet aim to boost movement in stroke and Parkinson's

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 18 years or older. * Able to understand the study procedures and follow study instructions. * Signed informed consent obtained before participation. * Adequate cognitive function, defined as Mini-Mental State Examination score ≥24 or equivalent clinical assessment. * Upper-limb functional limitation compatible with participation in the study. * QuickDASH score between 20 and 70. * Arm and forearm dimensions compatible with safe and appropriate fitting of the wearable device. Additional inclusion criteria for stroke participants * Clinically confirmed diagnosis of ischemic or hemorrhagic stroke, documented by computed tomography or magnetic resonance imaging. * Upper-limb motor impairment involving the proximal upper limb, including shoulder and/or elbow functional limitation. * Modified Ashworth Scale score \<3 in the affected upper limb. * Residual upper-limb motor function compatible with the assigned device-assisted experimental tasks. * Fugl-Meyer Assessment Upper Extremity score ≥15. Additional inclusion criteria for Parkinson's disease participants * Clinically confirmed diagnosis of idiopathic Parkinson's disease. * Modified Hoehn and Yahr stage II or III. * Upper-limb motor impairment such as bradykinesia, rigidity, tremor, or reduced dexterity. * Unified Parkinson's Disease Rating Scale Part III upper-limb motor items compatible with mild-to-moderate impairment. * Assessment performed in the "on" medication state, within two hours after levodopa intake. Exclusion Criteria: * Severe cognitive impairment, defined as Mini-Mental State Examination score \<24, or any condition preventing comprehension of study procedures or instructions. * Unstable medical condition that could increase risk during participation, including uncontrolled cardiovascular disease, severe respiratory failure, active systemic infection, or recent major surgery. * Dermatological disease, open wounds, skin lesions, or skin hypersensitivity in the areas where the wearable devices would be applied. * Contraindications to use of the study devices, including implanted pacemaker, relevant metallic implants near the application area, or known allergy to device materials. * Severe spasticity of the affected upper limb that would prevent safe device use, defined as Modified Ashworth Scale score ≥3. * Severe upper-limb pain that could be worsened by active or passive movement. * Participation in another interventional clinical study involving upper-limb rehabilitation or motor rehabilitation within 30 days before enrollment. * Use of investigational drugs or investigational treatments within 30 days before study participation. * Confirmed or suspected pregnancy. * Any condition that, in the investigator's judgment, could interfere with study procedures, affect participant safety, or expose the participant to undue risk. * Refusal or inability to provide signed informed consent.
