The goal of this clinical trial is to evaluate the DESC-Glove, an instrumented glove developed for sensorimotor rehabilitation in individuals recovering from a stroke, utilizing non-invasive vibrational feedback. The primary objective is to assess the technical functionality, safety, and reliability of the device during post-stroke rehabilitation, providing insights for future technical and functional improvements.
The secondary objectives are:
To meet the second objective, researchers will compare three groups:
an experimental treatment group (using the DESC-Glove during hand rehabilitation), a sham control group (using the DESC-Glove without vibration), and a conventional control group (receiving hand rehabilitation without the device).
The study is divided into two phases:
Phase 1: Preliminary Investigation of Device Functionality. This phase involves testing the DESC-Glove on 5 patients to assess its initial functionality. Each patient will complete four treatment sessions using the device, focusing on both fine motor exercises for the hand and gross motor exercises for the upper limb. This phase will also help evaluate patient compliance with the rehabilitation treatment on a smaller scale, allowing for a better understanding of the recovery process's duration. During the treatment, patients will wear the DESC-Glove on the affected hand, receiving vibratory stimuli synchronized with the exercises, following the device's operational guidelines.
Phase 2: Multicenter Randomized Controlled Trial (RCT).
In this phase, 42 participants will be recruited and randomly assigned to one of three parallel groups (1:1:1):
The experimental treatment group (using the DESC-Glove), The sham control group (using the DESC-Glove without vibration), and The conventional control group (not using the DESC-Glove). The sample size of 42 (14 participants per group) was chosen following Julious et al. [doi: 10.1002/pst.185], which recommends a minimum of 12 subjects per group for pilot studies. This number was increased to 42 to account for potential dropouts, ensuring robust data collection and analysis.

| For both the first and second phase of the study: baseline assessment (within 3 days before the first rehabilitation session) and final assessment (within 3 days after the last rehabilitation session). |
| Clinical outcome: Frenchay Arm Test | The Frenchay Arm Test (FAT) is an assessment tool designed to measure upper extremity proximal motor control and dexterity during activities of daily living (ADL) in patients with neurological impairments. It focuses on evaluating activity limitations specific to the upper extremities. Each of the test's five items is scored as either a pass (1) or fail (0), with total scores ranging from 0 to 5. | For both the first and second phase of the study: baseline assessment (within 3 days before the first rehabilitation session) and final assessment (within 3 days after the last rehabilitation session). |
| Clinical outcome: Thumb Localizing Test | The Thumb Localizing Test is an assessment used to evaluate proprioception and sensory awareness in the hand. During the test, the examiner places the participant's thumb in various positions, either passively or with minimal resistance, while the participant's eyes are closed. The participant is then asked to replicate the position of their thumb with their opposite hand or to indicate the position of their thumb using verbal or tactile cues. It ranges from 0 (normal) to 3 (severely impaired). | For both the first and second phase of the study: baseline assessment (within 3 days before the first rehabilitation session) and final assessment (within 3 days after the last rehabilitation session). |
| Clinical outcome: 5-level EQ-5D | The 5-level EQ-5D is a standardized instrument used to measure health-related quality of life. It consists of a descriptive system and a visual analogue scale (VAS). The descriptive system evaluates five dimensions of health - mobility, self-care, usual activities, pain/discomfort and anxiety/depression - each with five levels of severity. The result is calculated by assigning a numerical value to each response level and summing these values across the five items. | For both the first and second phase of the study: baseline assessment (within 3 days before the first rehabilitation session) and final assessment (within 3 days after the last rehabilitation session). |
| Instrumental Outcome: Pick and Lift test | The Pick and Lift Test (PLT) assesses the ability of participants to lift a sensorized object using a bi-digit grip with their thumb and index finger. During the test, participants repeatedly lift the object while the levels of force applied during the manipulation tasks are recorded. The PLT is conducted under three conditions: (a) with the DESC-Glove providing vibratory feedback, (b) with the DESC-Glove not providing vibrations, and (c) without the DESC-Glove altogether. This design allows for an evaluation of the impact of vibratory feedback on force application and manipulation skills. Such a system is not intended as a clinical validation tool but rather as a means of data acquisition to extract metrics considered standard in the scientific literature regarding motor coordination in manipulation. | For both the first and second phase of the study: Baseline (within 3 days before the first rehabilitation session); Weekly assessment (within 3 days after the last rehab session of each week). |
| Instrumental Outcome: Pick and Place test | The Pick and Place Test (PPT) with a fragile object involves performing a series of movements to transfer a fragile item from one side of a barrier to the other. This object walls collapse when the gripping force applied to these walls exceeds a certain threshold. It measures the participant's ability to regulate grip strength and dexterity. Such a system is not intended as a clinical validation tool but rather as a means of data acquisition to extract metrics considered standard in the scientific literature regarding motor coordination in manipulation. | For both the first and second phase of the study: baseline assessment (within 3 days before the first rehabilitation session) and final assessment (within 3 days after the last rehabilitation session). |
| Questionnaire: System Usability Scale | The system usability scale (SUS) is a simple, ten-item attitude Likert scale giving a global view of subjective assessments of usability. A SUS score can range from 0 to 100, with higher scores indicating better usability. This questionnaire will be evaluated exclusively within the experimental group. | For both the first and second phase of the study: final assessment (within 3 days after the last rehabilitation session). |
| Questionnaire: Gradibility of the Device | The Gradibility Questionnaire has been specifically designed to provide a thorough assessment of user experiences. It consists of 13 items that evaluate the usability, acceptability, and satisfaction of users testing the device. This questionnaire will be evaluated exclusively within the experimental group. | For both the first and second phase of the study: final assessment (within 3 days after the last rehabilitation session). |
| Questionnaire: Technology Acceptance Model | The Technology Acceptance Model is designed to identify the determinants influencing the acceptance of Robotic and Allied Technology. It comprises four sections: perceived usefulness, ease of use, compatibility, and intention to use. Each question utilizes a 7-point Likert scale, ranging from 1 (worst) to 7 (best). The scoring for each section is calculated as the average of the responses, with scores ranging from 1 (worst) to 7 (best). This questionnaire will be evaluated exclusively within the experimental group. | For both the first and second phase of the study: final assessment (within 3 days after the last rehabilitation session). |
