Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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:

1. To evaluate the usability and acceptability of the device in clinical rehabilitation from the perspectives of both patients and healthcare professionals;
2. To assess the short-term effects of the DESC-Glove on sensorimotor performance and manual dexterity in post-stroke individuals.

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).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Experimental Group

Hand rehabilitation using the device

Group Type EXPERIMENTAL

DESC-Glove (active)

Intervention Type DEVICE

Rehabilitation treatment for the upper limb using the DESC-Glove device. The protocol includes 8 exercises, each lasting 2 to 3 minutes. The treatment is conducted daily under the supervision of a therapist and consists of two 20-minute sessions per day, with a 10-minute break in between for neuro-muscular and attentional recovery. The treatment is performed three times a week, totaling 24 sessions over a 4-week period. During each session, patients will wear the DESC-Glove on the affected hand, receiving vibratory stimuli that are synchronized with the exercises being performed.

Sham Group

Hand rehabilitation while wearing the device, without providing vibrations to the patients.

Group Type SHAM_COMPARATOR

DESC-Glove (sham)

Intervention Type DEVICE

Rehabilitation treatment for the upper limb using the DESC-Glove device. The protocol includes 8 exercises, each lasting 2 to 3 minutes. The treatment is conducted daily under the supervision of a therapist and consists of two 20-minute sessions per day, with a 10-minute break in between for neuro-muscular and attentional recovery. The treatment is performed three times a week, totaling 24 sessions over a 4-week period. During each session, patients will wear the DESC-Glove on the affected hand, but will not receive any vibratory stimuli.

Control Group

Hand rehabilitation without using the device

Group Type ACTIVE_COMPARATOR

Traditional rehabilitation

Intervention Type OTHER

Traditional rehabilitation treatment for the upper limb. The protocol includes 8 exercises, each lasting 2 to 3 minutes. The treatment is conducted daily under the supervision of a therapist and consists of two 20- minute sessions per day, with a 10-minute break in between for neuro-muscular and attentional recovery. The treatment is performed three times a week, totaling 24 sessions over a 4-week period. The DESC- Glove will not be used during this treatment.
